OMVC
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 Industry trade group, trade ...

Mobile Television
Mobile television is television watched on a small handheld or mobile device, typically developed for that purpose. 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 a 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 ... [...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 the 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 have been fixed since the beginning ...

Beta Test
The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public. Pre-alpha refers to the early stages of development, when the software is still being designed and built. Alpha testing is the first phase of formal testing, during which the software is tested internally using white-box techniques. Beta testing is the next phase, in which the software is tested by a larger group of users, typically outside of the organization that developed it. The beta phase is focused on reducing impacts on users and may include usability testing. After beta testing, the software may go through one or more release candidate phases, in which it is refined and tested further, before the final version is released. Some software, particularly in the internet and technolo ... [...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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
