Cord-Cutting: Answers for a Friend

Streaming Devices5

I got a message from a friend on Facebook saying she had cut the cord. I never thought of her as impulsive, so I was a little surprised that she waited until she cancelled her cable to ask, “what do I do for TV now?” The truth was, she didn’t care. She just knew she wasn’t going to pay her cable bill any longer.

I wrote up some thoughts and shot them over to her. She then suggested that I write a blog post because she has so many friends that are also considering making the move. Now that we have Broadcast Blog, I’ll share a redux of those thoughts.

The big thing most cord-cutters want is continued access to their favorite channels and shows, which typically air on local broadcast television affiliates of ABC, CBS, FOX, NBC, Univision, PBS, ION and others. They also want on-demand access to other shows or movies. Good news: all of these channels are available for free via over-the-air (OTA) wireless broadcast signals, and there are a variety of over-the-top (OTT) streaming services that will provide access to on-demand programming.

OTA

To start, you need an antenna to pick up the OTA broadcast stations. As an added benefit, the OTA signal will often give you the best quality high-definition (HD) picture as the image hasn’t gone through the additional compression of the cable systems.

When trying to determine the correct antenna type for your location and viewing preferences, check out AntennaWeb.org. This site gives you the distance and directions of nearby towers as well as advice on what antenna might be best for you, based on your home address. I entered the zip code for my home address and you can see that I can get up to 76 channels from 29 OTA broadcasters.

If possible, I recommend buying an outdoor antenna and placing it on a rotor (this can be very useful if your home is situated between a number of towers) and then simply tie it into where your cable line used to enter your home; that way all of your TVs will benefit from this good outdoor antenna reception. With that being said, in many cases all you need is an antenna in the attic or something simple near your TV for indoor reception. When purchasing, I recommend taking a look at the manufacturers Antennas Direct and Channel Master.

Now, if you’d like to record some shows from your OTA feeds you can do that too. The Tivo Roamio has a honkin’ hard drive and it also has a program guide ($15/month subscription) for scheduling and recording your shows. The subscription is only necessary if you want to schedule a TV recording. Channel Master’s DVR+ has two different storage size options and a free program guide. Plus, it has two tuners, so you can watch one show while you are recording another. Tablo DVR comes with four tuners.

The nice thing about these units is they also provide access to OTT streaming services like Amazon, Netflix, YouTube, VUDU, and more. More about that below.

OTT 

Streaming services like Amazon, Netflix, Hulu, VUDU and  are all examples of OTT solutions that have a lot to offer at a fraction of the price of the average cable package. There are a wide variety of devices that enable access to these services as well as original content from these companies.

In addition to the Tivo Roamio, Channel Master DVR+ and Tablo DVR  mentioned above, some other popular OTT devices include:

For me personally, I start with Amazon because they include lots of content with my Prime membership. I love that 2-day shipping, and giving me instant access to video makes it even cooler. Plus, it is already built into many devices listed above. Next on my list is Netflix. I also use AppleTV, because it frequently has the best picture quality in my opinion and I can download and playback later on my laptop, tablet or phone.

I should qualify all of this by saying I still have a robust video subscription with Verizon FIOS, so I’m not currently a cord-cutter (though I have been in the past). I enjoy the convenience of my FIOS subscription, but there is no doubt that cord-cutting is more than a fad. PBS reports that in the past five years, 3.8 million households have already cut the cord. According to USA Today, perhaps another 7% of households are expected to drop their cable subscription and rely on over-the-air broadcast television and online streaming services.

FCC and Broadcasters Focusing on Field Enforcement

FCC field office map

Last March the FCC put forth what turned out to be a controversial plan to modernize and reduce the Commission’s field enforcement activities, resulting in significant review and comment by industry stakeholders as well as members of the U.S. Congress. In the midst of these discussions about Field Offices, the Commission in June hosted a “Pirate Radio Roundtable” focusing on strategies to combat illegal pirate radio operations. These activities recently culminated in the release of an FCC Order on reorganization of the Enforcement Bureau’s field operations and a letter from NAB to FCC Chairman Wheeler summarizing ideas from the Pirate Radio Roundtable for possible actions to combat Pirate Radio.

The FCC’s Order, released July 16, 2015, outlines several actions to realign the mission and resources of the FCC field offices and Equipment Development Group. Most notably, the Order closes completely eight of the 24 current field offices and closes an additional three offices with plans to still maintain a “local presence” in these cities (Anchorage, Kansas City, and San Juan). The table and map shown here summarize these office closure actions.

LOCATION OFFICE TYPE STATUS
Anchorage, AK Resident Agent CLOSED – LOCAL PRESENCE MAINTAINED
Atlanta, GA District RELOCATED NEARBY
Boston, MA District OPEN
Buffalo, NY Resident Agent CLOSED                                                       
Chicago, IL District OPEN
Columbia, MD District RELOCATED NEARBY
Dallas, TX District OPEN
Denver, CO District OPEN
Detroit, MI District CLOSED                                                       
Honolulu, HI Resident Agent OPEN
Houston, TX Resident Agent CLOSED                                                       
Kansas City, MO District CLOSED – LOCAL PRESENCE MAINTAINED
Los Angeles, CA District OPEN
Miami, FL Resident Agent OPEN
New Orleans, LA District OPEN
New York, NY District OPEN
Norfolk, VA Resident Agent CLOSED                                                       
Philadelphia, PA District CLOSED                                                       
Portland, OR Resident Agent OPEN
San Diego, CA District CLOSED                                                       
San Francisco, CA District RELOCATED NEARBY
San Juan, PR Resident Agent CLOSED – LOCAL PRESENCE MAINTAINED
Seattle, WA District CLOSED                                                       

More generally, the Order directs the field offices to embark on a program to update equipment and employee skillsets to address the likely issues that will accompany new and expanded uses of spectrum. The Commission wants this program to include the expanded use of remotely operated monitoring equipment to supplement field staff, as well as the identification and use of portable devices capable of assessing interference issues in bands expected to experience heavy spectrum use.  The Order also stipulates that:

  • all Bureau field agents shall have electrical engineering backgrounds;
  • within six weeks of release of the Order, the Bureau will establish procedures for industry and public safety complainants to escalate their complaints within the Field organization;
  • the Commission will continue to work with outside stakeholders to develop a comprehensive policy and enforcement approach to the issue of unlicensed radio broadcasting;

the Commission will implement a nationwide outplacement effort to assist all displaced employees to find positions in the public or private sectors, including other vacancies within the Commission for which they are qualified and selected.

In an NAB news release on the FCC Order, NAB Executive Vice President of Communications Dennis Wharton said that “NAB appreciates the work of both the FCC and Congress in forging a compromise FCC field office proposal that keeps open many more enforcement offices than was originally proposed. We also thank both Republican and Democratic commissioners for expressing a need to better enforce prohibition against pirate radio stations. NAB looks forward to working with all stakeholders to police the airwaves against these illegal operations.”

In a separate but related matter, on July 17, 2015, NAB General Counsel and Executive Vice President Rick Kaplan sent a letter to FCC Chairman Wheeler with a list of ideas resulting from the FCC’s “Pirate Radio Roundtable” focusing on strategies to combat illegal pirate radio operations. At the Roundtable discussion it was noted that pirate radio operations erode the advertising and membership base of legitimate broadcast stations (both full- and low-power), and undermine investment in legitimate stations, particularly minority-owned stations. They also threaten the health and safety of radio listeners and local residents. Pirate radio operations disrupt the Emergency Alert System (EAS), interfere with aviation frequencies and often transmit from residential buildings where unchecked RF radiation can cause health problems.

Some of the suggestions generated at the Roundtable discussion are summarized in the NAB letter and include the following:

  • Significantly increase the number of enforcement actions, including Notices of Apparent Liability, Forfeitures and equipment seizures issued by the FCC against pirate operators. This effort should begin immediately as the number of pirate radio stations often increases during the summer months. While the Enforcement Bureau has issued hundreds of Notices of Unlicensed Operation, it has issued relatively few fines or equipment seizures;
  • Develop a Commission policy statement to share with private and law enforcement groups and help channel Commission resources towards pirate radio enforcement;
  • Implement a dual strategy that increases pirate enforcement effort in the short term using all existing enforcement tools while working on changes in the Communications Act and other federal laws to improve enforcement against pirate radio. This will include a legislative strategy for expanding the Commission’s authority to prosecute pirate radio operators, including coordination with the Federal Aviation Authority and the Federal Emergency Management Agency;
  • Raise the awareness of entities (e.g., concert venues, building owners and managers, advertisers) that may unknowingly aid and abet pirate radio operators. Develop best practices with representative trade associations and organizations;
  • Enlist law enforcement entities that can serve as partners in education efforts;
  • Enhance the Commission’s ability to identify and prosecute pirate operators, including the continued assistance of broadcasters in locating illegal radio transmitters and studios;
  • Further examine the impact of pirate radio on the nation’s EAS system;
  • Create a permanent liaison between the Commission, U.S. Attorney’s Offices, US Marshal’s service, and state and local law enforcement agencies to facilitate pirate radio enforcement;
  • Explore using private sector engineers to help FCC offices work with local law enforcement in a more efficient manner.

Media Monitoring with Big Data: Opportunities and Challenges

What would marketing strategists do if every second of all broadcast television, broadcast radio, and social media posts were available in real time for analysis? How would advertisers react if the transcripts of all the TV and radio broadcast information were available in addition to video and audio for every second anywhere in the nation in real time? Big Data analytics provides a means to digest this copious amount of information and to make ad buying decisions on the fly.

Big Data analytics means not only processing very large amounts of data but also attempting to coherently connect the unstructured nature of the data. For example, the data could be a combination of radio and TV transmissions converted into speech by a speech coder, closed caption text of TV programs, Twitter and Facebook posts, financial data and spreadsheets, and news articles. Another advantage of Big Data analytics is that the system is self-learning; once the initial analytical model has been created, additional new data and information can be easily integrated into the knowledge base. Big Data analytics has been creating a buzz in the industry for a number of years, and many companies are already offering tools and services to reap the benefits.

An example of a company that archives broadcast content for media monitoring is Critical Mention. Critical Mention captures and indexes 40 hours of broadcast content every 60 seconds from more than 2,000 unique broadcast sources. The users thus have access to a database of more than 16 million searchable segments, all available in broadcast quality and near-real time. The users can search TV/radio/online news, watch video, edit and share coverage, receive real-time alerts, and create reports. The system also offers analytic tools to gain insight into the data, to benchmark against competitors, to analyze viewer sentiment, and to visualize density of coverage on maps. The following picture is an example of the analysis tool output.

Figure: Critical Mention Analytics

Integration of Big Data analytics with archived media information would open up many new possibilities in the future. For example, the single string-based search provided by Critical Mention can be augmented to perform searches based on different combinations of groups of words. Grouping of related words and inclusion/exclusion combinations of many different groups are known as dictionaries and rules in Big Data jargon, and these well known techniques are used to isolate relevant information and validate hypotheses. The natural language processing (NLP) capabilities of big data can also help make inference about the context in which the key words are used, making the results more reliable and relevant. Yet one can envision that image processing and pattern matching algorithms could be used to detect and quantify product placement in broadcast video. For example, the Coke logo can be identified in time-stamped video frames across all the broadcasters of all the DMAs in real time. These capabilities are computationally intensive, but the algorithms are fairly well understood. Cloud services, which offer scalable computational resources, can make this kind of analysis available in the future.

Recognizing some of these potential business opportunities, broadcasters and consumer electronics manufacturers are developing a next-generation television system with dynamic ad insertion and targeted advertising capabilities. If ad buyers can identify a need – in real-time if they wish – to maintain their brands’ share of voice (SOV) in certain geographically segmented markets, broadcasters will have the technical means to deliver the ads to the intended audience in the future. As a consequence, programmatic advertising and ad exchange might become more dynamic in terms of balancing demand and supply.

This kind of individualized targeting might also raise challenges to traditional advertising models in the broadcast industry. With access to all the real-time and personalized information of the audience, an ad buyer will have the option to use different means to reach the audience, even when the audience is consuming broadcast content. For example, armed with the knowledge of a consumer’s state of mind at a certain location at a certain instant, the ad buyer might reach the targeted customer through a smartphone, thus totally bypassing the broadcasters. Proliferation of the Internet of Things (IoT) will provide more outlets for targeted advertising, and the situation might become even more challenging for the traditional broadcasting model.

Media monitoring along with Big Data analytics has tremendous potential for targeted and contextual advertising. The advertising industry is changing rapidly, revealing both opportunities and challenges for broadcasters. Broadcasters will need to be vigilant of this fundamental paradigm shift in advertising and adapt to new market challenges.

Is Broadcast Part of the Solution to Internet Traffic Congestion?

Akamai’s Chief Architect Will Law talked about the trends of Internet connectivity at the ATSC Broadcast Television Conference held on May 14, 2015 in Washington DC. He identified that delivering high quality video will be a challenge to the Internet infrastructure in the future, and that integration of broadcast and Internet could be a solution to that problem.

Akamai’s Intelligent Platform™ is a leading cloud platform that delivers secure, high-performing user experiences. The platform is a globally distributed network of servers and intelligent software, and it handles over two trillion interactions daily. Through this platform Akamai has gathered insightful metrics such as connection speed, network availability, traffic patterns, etc. over different geographical regions. Akamai’s Chief Architect shared some of the data and statistics with the ATSC Broadcast Television Conference audience.

Although average connection speed is increasing across the US, there are significant disparities among the states. It is generally accepted among Internet providers that OTT delivery of a 4K UHD signal would require about a 15 Mbps internet pipe. The following figure shows that many states are not yet ready to support a widespread 4K UHD OTT service.

Akamai also showed that peak bandwidth demand varies with time and coincides with big events.  Moreover, the peak bandwidth demand also increases year by year. The following figure shows that the peak bandwidth demand is spiky and that the envelope of the peaks is growing.

pic2

Factors that are driving the demand for higher Internet speed are 4K/UHD video, OTT services, catch-up TV, device-based video playback outside the living room, and increasing user expectations of quality. There are a few potential solutions to the bandwidth challenge: better compression (HEVC), growth in average throughput, backbone fiber improvements, hybrid UDP protocols, possibility of IP multicast, P2P, HTTP2, standards such as MPEG-DASH, decreasing cost of storage, and broadcast integration.

Akamai’s solution to the bandwidth problem is to place edge servers near the end user, as shown in the following figure. The edge server, marked as an orange box, is physically near the end user; this kind of placement reduces the burden of fetching the content from distant sources and thus reduces overall internet traffic.

Broadcasters have several opportunities in this environment. First, they could form a partnership with CDN providers and collaborate with caching content on the edge servers.  Second, using new technologies such as ATSC 3.0, broadcasters could reach many of the end users directly over the air, especially during the large bandwidth demand spikes associated with big events. If terrestrial broadcasts are integrated with broadband networks, service to consumers will be optimized from the combination of the inherent flexibility of the Internet and the high spectrum efficiency of broadcast delivery.

HDR2

First HDR/WCG Television Ecosystem Established

At the 2015 NAB Show, Dolby Laboratories announced that it had established the first video high dynamic range and wide color gamut television ecosystem, combining content creators with a content distributor and TV display manufacturer, all deployed around its proprietary video format called Dolby Vision.

The Ultra High-Definition (UHD) video space continues to develop its extensions beyond HDTV, along the multiple axes of greater spatial definition, higher luminance dynamic range (HDR), wider color gamut (WCG), and higher frame rate (HFR). Numerous proposals have been put forward in this environment by a number of organizations, and standards are under development in various SDOs, including ATSC (as part of the ATSC 3.0 next-generation TV standard) and SMPTE. To date, however, there have been no comprehensive decisions made on precisely what constitutes a complete UHDTV delivery format. The only real agreement to date has been on spatial resolution for first-generation UHD, at 3840 x 2160 pixels (“4K”).

Although a participant in these standardization processes, Dolby has simultaneously put forward its proprietary format, albeit in a limited manner, via the over-the-top (OTT) Internet TV environment. The partners in the ecosystem to date include Warner Bros. (which has developed a few items of feature-film content in the format), Walmart’s VUDU OTT service, and TV manufacturer Vizio. At the initial announcement on April 13, 2015, Vizio planned to offer Dolby Vision support on both HD and 4K televisions of up to 120 inch display size, although availability dates and prices have not yet been specified.

There have been hints that this initial consortium of players may expand, but even in its currently limited arrangement, the Dolby announcement is a shot across the bow to the standards development players, indicating that proprietary, end-to-end alliances are possible in the UHD space. This implies that if true de jure standards are not developed soon, there is risk that a number of de facto“standards” could emerge and dilute any effort for a singular industry format to attain critical mass around HDR and/or WCG. Thus even such a limited grouping as the current Dolby Vision initiative puts pressure on broader standards initiatives to accelerate their activities. Meanwhile, the process also may generate valuable learning for SDOs as to what elements of UHD appeal most strongly to consumers.

(Incidentally, in an attempt to avoid divergence and possible balkanization among UHD formats, two industry groups recently have been formed—the UHD Alliance and the UHD Forum. The former allies content creators with display manufacturers for the proper and uniform realization of producers’ intent, while the latter and more nascent group intends to coalesce common practices for distribution and transmission of UHD content.)

Technically, the Dolby Vision approach sets a dynamic range that extends the maximum luminance capability of the HDR display from its current level of 100 candela per square meter (cd/m2, generally referred to as “nits”) in television to 10,000 nits. (The latter extreme is expected to be used only for adding small highlights, while more typical bright picture elements might range around 1,000 nits.) Dolby cites subjective testing of viewers that it conducted in determining this range (see figure below), and although the current Vizio displays only reach 800 nits, the resulting images are noticeably improved to most viewers when compared with standard luminance displays. This had led many industry observers to the belief that HDR and WCG (and perhaps also HFR) may be more important than spatial resolution (4K) alone for broad adoption of UHDTV.

The Dolby Vision format also includes an adaptation of WCG tailored to its extended luminance range. Rather than simply adapting current practice in the electro-optical transfer function (EOTF), Dolby proposes a perceptually based quantization method (PQ), allowing what might require up to 15 bits for each video sample to be reduced to 12 bits, and still deliver perceptually effective HDR and WCG images.

Another key issue is backward compatibility. For example, given that new TV screens are required to display HDR content (even at HD resolutions), will the same content display properly on standard dynamic range (SDR) screens, or will two discrete versions of the content be required? Naturally, it would be preferred if a single content format could be developed that provides HDR quality to HDR-capable displays but still renders acceptable pictures to SDR displays, similar to how HD content is handled by SD displays today. Experts have noted, however, that such HDR-to-SDR compatibility and the management of multiple color spaces are more challenging than simply rescaling spatial resolution across multiple display types. Said another way, HDR and WCG are about the quality of pixels, not the quantity of them.

Although obviously quite active in the UHD space, Dolby is not alone, with substantial effort and prototype formats or hardware also being developed by Sony, Samsung, Technicolor, LG and others. And while not as mature as development in the spatial resolution area, it has become generally acknowledged that HDR and WCG (and possibly HFR) are important elements that should be included in any initial UHDTV delivery standard. Developers in these areas are therefore under pressure to bring their work to a point at which it can be considered for standardization, so developments like the Dolby Vision announcement can have significant impact upon the progress of next-generation TV standards like ATSC 3.0.
