DTV Audio Group Sets Agenda for AES Show

Tue, 02 Sep 2014 15:36:51 -0400

The DTV Audio Group has announced the agenda for its annual Forum at the Audio Engineering Society (AES) Convention, which takes place Oct. 9-12 at the Los Angeles Convention Center in downtown L.A.

The event, titled “The Implications of Streamed Content Delivery on the Evolution of Television Audio Services,” will take place on Friday, Oct. 10 from 1 p.m. to 6 p.m. and will include panel discussions and presentations on these timely topics:

This Is Not Your Father’s MVPD — A look into how the transition to IP infrastructure and streamed content is transforming cable and how this facilitates advanced audio codecs
So Long, SDI and MADI — IP infrastructure for audio and video contribution within the broadcast plant and in the field
Interactivity, Objects, and Spatially Immersive Audio — Mixers and technologist on the migration of object audio from cinema to the small screen and mobile
Object Audio Toolbox — What are the essential monitoring and authoring tools required for object audio production?
It’s All in Your Head — The state of headphone virtualization for immersive audio formats.

“Content delivery is converging on a streamed model whether for mobile, over the public Internet, within the walled garden of the MVPD, or over next-generation broadcast services,” observes Roger Charlesworth, executive director, DTV Audio Group. “Virtualized-delivery infrastructure for streamed content allows new services to be deployed with very short lead times. The rapidity of this transition to streaming has significantly accelerated the time frame for adoption of advanced object-based audio services offering spatially immersive sound, enhanced personalization, greater bandwidth efficiency, and improved audio quality.

“It is likely we will begin seeing these new features in our homes and mobile devices in months rather than years,” he continues. “This forum explores some of the tools and workflow approaches required to manage and exploit the capabilities of next-generation audio standards. It takes a look at the convergence around streamed-content delivery and transition to IP distribution and contribution that makes this rapid deployment possible.

“The explosive growth in streamed-content delivery over mobile and fixed devices has re-written the playbook for television media distribution. Streaming-delivery models are also inexorably finding their way into existing cable services and are being written into next-generation advanced television standards. The migration from traditional broadcasting to an IP stream-based model greatly simplifies implementation and, combined with tablet-empowered UI, frees distributors to pursue a range of formats and encoding solutions with sophisticated interactive and object-oriented audio services.”

Energy Efficient Set-Top Boxes Saving Consumers Hundreds of Millions of Dollars

Fri, 29 Aug 2014 10:28:13 -0400

A new report released today shows that the voluntary set-top box energy conservation agreement between the pay-TV industry, consumer electronics manufacturers and energy efficiency advocates has saved American consumers approximately $168 million in energy bills. According to the Voluntary Agreement for Ongoing Improvement to the Energy Efficiency of Set-Top Boxes 2013 Annual Report, the improved energy efficiency of set-top boxes also represents a savings of nearly 842,000 metric tons of carbon dioxide (CO2) per year. This is equivalent to the output of one-half of a large (500MW) power plant.

Eighty-five percent of set-top boxes purchased by pay-TV providers in 2013 met the U.S. Environmental Protection Agency (EPA) ENERGY STAR 3.0 efficiency levels. New set-top boxes use approximately 14 percent less energy than those previously issued by the service providers.

In 2012, the pay-TV industry initiated a Voluntary Agreement that would eventually result in annual electricity savings of $1 billion or more, as the energy efficiency of set-top boxes is increased by up to 45 percent. Agreement signatories include 11 cable, satellite, and telco video companies and all major equipment vendors serving 91.9 million U.S. video subscribers, accounting for 91.3 percent of the total market in 2013. In 2013, leading energy-efficiency advocates joined with the pay-TV industry in an expanded version of the Voluntary Agreement.

One of the requirements of the Voluntary Agreement is the publication of an annual report, which was conducted by D&R International. The Independent Administrator, hired and funded by the Voluntary Agreement Steering Committee following a competitive bidding process, collected data directly from service providers before aggregating and incorporating the data in the report.

“These collective efforts of the cable, satellite, and telephone industries demonstrate a commitment to delivering innovative video services while at the same time saving energy in our customers’ homes,” said Michael Powell, President & CEO, NCTA. “A big part of innovation is making sure we are good stewards of the environment, so these providers and device manufacturers will continue to look for new ways to conserve energy in delivering services.”

Time Warner Cable to Pay $1.1M to Resolve Outage Reporting Violations

Thu, 28 Aug 2014 10:05:43 -0400

By the Acting Chief, FCC Enforcement Bureau:

The Enforcement Bureau of the Federal Communications Commission has resolved its investigation into whether Time Warner Cable, Inc. (TWC) complied with the Commission’s network outage reporting requirements. Under these rules, communications providers must report certain disruptions to their networks. The Commission has determined that prompt access to accurate information regarding the operation and security of crucial segments of the national telecommunications infrastructure would enable it to prevent disruptions in service that could threaten homeland security, public health and safety, as well as our nation's economic well-being, and would facilitate alternative means of communicating. Depending upon the nature of the network outage, communications providers must file certain reports with the Commission within defined timeframes. By requiring communications providers to report certain disruptions to their networks, these rules provide the Commission with the means to quickly analyze communications vulnerabilities and share aggregate information with industry to help prevent future outages and preserve network integrity. Here, TWC failed to file a substantial number of reports with respect to a series of reportable wireline and Voice over Internet Protocol network outages. TWC admits that its failure to timely file the required network outage reports violated the Commission’s rules. To resolve the investigation, TWC will pay a civil penalty of $1.1 million and implement a three-year compliance plan to ensure future compliance with the Commission’s network outage reporting rules.

Grass Valley to Host Webinar on Maximizing ROI For Automated Production

Wed, 27 Aug 2014 10:50:12 -0400

On August 28, Grass Valley will host a free webinar that will take a look at how the current state of the art in automated production goes farther than ever before in minimizing cost and maximizing production value — and serves as a portal for digital media content delivery that can substantially increase revenue.

The webinar, which will begin at 11 a.m. ET, will tackle:

Sizing the system – It’s smaller than you think
Operational staffing models
Moving the work upstream – prepare more, do less during the live broadcast
Adding digital publishing cues to the live production

According to Grass Valley, sophisticated device control and event-sequencing software are increasingly becoming the norm in automated production systems. While originally used almost exclusively in news operations, these systems are rapidly gaining acceptance in other types of television production. Although it has been shown to improve on-air quality, the decision to implement automated production remains rooted in ROI considerations based on cost savings.

A duplex communication system is a system composed of two connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for a communication "two-way street" between two connected parties or to provide a "reverse path" for the monitoring and remote adjustment of equipment in the field.
Systems that do not need the duplex capability include broadcast systems, where one station transmits, and everyone else just "listens". A half-duplex system provides for communication in both directions, but only one direction at a time (not simultaneously). Typically, once a party begins receiving a signal, it must wait for the transmitter to stop transmitting, before replying. A full-duplex, or sometimes double-duplex system, allows communication in both directions, and, unlike half-duplex, allows this to happen simultaneously. Land-line telephone networks are full-duplex, since they allow both callers to speak and be heard at the same time.

Black Box Explains...The difference Between SurgeArrest and Power Strips

It says UL listed, so it must be okay, right?

Not necessarily.

UL listed means that a product has been submitted to Underwriter’s Laboratories for safety testing in certain categories. The strip protector you just bought is most likely listed in the extension cord category. It won’t stop harmful surges from destroying equipment data.

The UL listing for surge suppressors is UL 1449. APC SurgeArrest products received the best UL 1449 rating. Some vendors rate surge protection on the basis of joule energy. But let-through should be compared.

APC surge protectors undergo stringent testing by IEEE, and are awarded "let-through ratings", which indicate the maximum voltage level that can possibly reach your equipment after a surge or voltage spike has passed through an electric surge protector. Lower IEEE let-through ratings indicate better protection and performance.

While most other surge suppressors continue to let power through even after their circuits have been damaged - leaving your equipment exposed to future surges, APC's SurgeArrest uses a fail safe design, which means that once the circuit of an APC SurgeArrest has been compromised the unit disconnects equipment from the power supply ensuring that no damaging surges reach your equipment.
