Open Mobile Video Coalition
The Open Mobile Video Coalition (OMVC) is a consortium founded to advance free broadcast mobile television in the United States. It was created by TV stations to promote the ATSC-M/H television standard to consumers, electronics manufacturers, the wireless industry, and the Federal Communications Commission. The OMVC set-up the first real-life beta tests for ATSC-M/H on WATL and WPXA in Atlanta, and on KOMO and KONG in Seattle. Most recently, it has also advocated to the FCC, trying to keep it from taking even more of the UHF upper-band TV channels for wireless broadband. The OMVC commissioned a study to emphasize the fact that broadcasting is a far more efficient use of bandwidth than unicasting the same live video stream hundreds of times to every mobile phone that wants to watch local television. As of January 1, 2013 the OMVC became integrated in the National Association of Broadcasters The National Association of Broadcasters (NAB) is a trade association and lobby g ...

Mobile Television
Mobile television is television watched on a small handheld or mobile device. It includes service delivered via mobile phone networks, received free-to-air via terrestrial television stations, or via satellite broadcast. Regular broadcast standards or special mobile TV transmission formats can be used. Additional features include downloading TV programs and podcasts from the Internet and storing programming for later viewing. According to the ''Harvard Business Review'', the growing adoption of smartphones allowed users to watch as much mobile video in three days of the 2010 Winter Olympics as they watched throughout the entire 2008 Summer Olympics, a five-fold increase. However, except in South Korea, consumer acceptance of broadcast mobile TV has been limited due to lack of compatible devices. Early mobile TV receivers were based on old analog television systems. They were the earliest televisions that could be placed in a coat pocket. The first was the Panasonic IC TV MODEL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ATSC-M/H
ATSC-M/H (''Advanced Television Systems Committee - Mobile/Handheld'') is a U.S. standard for mobile digital TV that allows TV broadcasts to be received by mobile devices. ATSC-M/H is a mobile TV extension to preexisting terrestrial TV broadcasting standard ATSC A/53. It corresponds to the European DVB-H and 1seg extensions of DVB-T and ISDB-T terrestrial digital TV standards respectively. ATSC is optimized for a fixed reception in the typical North American environment and uses 8VSB modulation. The ATSC transmission method is not robust enough against Doppler shift and multipath radio interference in mobile environments, and is designed for highly directional fixed antennas. To overcome these issues, additional channel coding mechanisms are introduced in ATSC-M/H to protect the signal. As of 2021, ATSC-M/H is considered to have been a commercial failure. Evolution of mobile TV standard Requirements Several requirements of the new standard were fixed right from the beginning: * ...

Federal Communications Commission
The Federal Communications Commission (FCC) is an independent agency of the United States federal government that regulates communications by radio, television, wire, satellite, and cable across the United States. The FCC maintains jurisdiction over the areas of broadband access, fair competition, radio frequency use, media responsibility, public safety, and homeland security. The FCC was formed by the Communications Act of 1934 to replace the radio regulation functions of the Federal Radio Commission. The FCC took over wire communication regulation from the Interstate Commerce Commission. The FCC's mandated jurisdiction covers the 50 states, the District of Columbia, and the territories of the United States. The FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries of North America. The FCC is funded entirely by regulatory fees. It has an estimated fiscal-2022 budget of US $388 million. It has 1,482 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beta Test
A software release life cycle is the sum of the stages of development and maturity for a piece of computer software ranging from its initial development to its eventual release, and including updated versions of the released version to help improve the software or fix software bugs still present in the software. There are several models for such a life cycle. A common method is that suggested by Microsoft, which divides software development into five phases: Pre-alpha, Alpha, Beta, Release candidate, and Stable. Pre-alpha refers to all activities performed during the software project before formal testing. The alpha phase generally begins when the software is feature complete but likely to contain several known or unknown bugs. The beta phase generally begins when the software is deemed feature complete, yet likely to contain several known or unknown bugs. Software in the production phase will generally have many more bugs in it than completed software, as well as speed/performan ...

WPXA-TV
WPXA-TV (channel 14) is a television station licensed to Rome, Georgia, United States, broadcasting the Ion Television network to the Atlanta area. The station is owned and operated by the Ion Media subsidiary of the E. W. Scripps Company, and maintains offices on North Cobb Parkway (US 41) in Marietta; its transmitter is located on Bear Mountain, near the Cherokee– Bartow county line. Despite Rome being WPXA-TV's city of license, the station maintains no physical presence there. The station's broadcast range extends into parts of Alabama and Chattanooga, Tennessee and even the southwest corner of North Carolina. However, terrain shielding not accounted for in radio propagation models prevents this from regularly occurring, due to the north Georgia mountains. History The station was issued a construction permit in 1984 on Channel 14 as WZGA, but never made it to air. The station went on-air February 29, 1988 as WAWA, with studios on Shorter Avenue in Rome and transmitter on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Band V
Band V (meaning ''Band 5'') is the name of a radio frequency range within the ultra high frequency part of the electromagnetic spectrum. It is not to be confused with the ''V band'' in the extremely high frequency part of the spectrum. Sources differ on the exact frequency range of ''UHF Band V''. For example, the ''Broadcast engineer's reference book'' and the BBC define the range as 614 to 854 MHz. The '' IPTV India Forum'' define the range as 582 to 806 MHz and the '' DVB Worldwide'' website refers to the range as 585 to 806 MHz. Band V is primarily used for analogue and digital (DVB-T & ATSC) television broadcasting, as well as radio microphones and services intended for mobile devices such as DVB-H. With the close-down of analog television services most countries have auctioned off frequencies from 694 MHz and up to 4G cellular network providers. Television Australia In Australia UHF channel allocations are 7 MHz wide. Band V includes channels 36 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
