Mobile TV Format
Mobile TV Format is a colloquial and collective name for technology standards set out for broadcasting TV services to mobile devices, mostly mobile handsets for now. Currently, there are four prevalent formats known as DMB, DVB-H, OneSeg and MediaFLO. As of December 2007, ITU approved T-DMB, DVB-H, OneSeg and MediaFLO as the global standard for real-time mobile video and audio broadcasting. Thus far, none of the four formats has secured a dominant position in the global market, except in their respective home markets. History Samsung and LG were the first to tout new generation mobile phones that would allow users to watch live multi-channel TV on the move during International Broadcasting Convention (IBC) in Amsterdam in September 2005. South Korea's top mobile operator SK Telecom SK Telecom Co., Ltd.

DVB-H
DVB-H (Digital Video Broadcasting - Handheld) is one of three prevalent mobile TV formats. It is a technical specification for bringing broadcast services to mobile handsets. DVB-H was formally adopted as ETSI standard EN 302 304 in November 2004. The DVB-H specification (EN 302 304) can be downloaded from the official DVB-H website. From March 2008, DVB-H is officially endorsed by the European Union as the "preferred technology for terrestrial mobile broadcasting". The major competitors of this technology are Qualcomm's MediaFLO system, the 3G cellular system based MBMS mobile-TV standard, and the ATSC-M/H format in the U.S. DVB-SH (Satellite to Handhelds) now and DVB-NGH (Next Generation Handheld) in the future are possible enhancements to DVB-H, providing improved spectral efficiency and better modulation flexibility. DVB-H has been a commercial failure, and the service is no longer on-air. Ukraine was the last country with a nationwide broadcast in DVB-H, which began trans ...

OneSeg
is a mobile terrestrial digital audio/video and data broadcasting service in Japan, Argentina, Brazil, Chile, Uruguay, Paraguay, Peru and the Philippines. Service began experimentally during 2005 and commercially on April 1, 2006. It is designed as a component of ISDB-T, the terrestrial digital broadcast system used in those countries, as each channel is divided into 13 segments, with a further segment separating it from the next channel; an HDTV broadcast signal occupies 12 segments, leaving the remaining (13th) segment for mobile receivers, hence the name, "1seg" or "One Seg". Its use in Brazil was established in late 2007 (starting in just a few cities), with a slight difference from the Japanese counterpart: it is broadcast under a 30 frame/s transmission setting (Japanese broadcasts are under the 15 frame/s transmission setting). Technical information The ISDB-T system uses the UHF band at frequencies between 470 and 770 MHz (806 MHz in Brazil), giving a to ...

MediaFLO
MediaFLO was a technology developed by Qualcomm for transmitting audio, video and data to portable devices such as mobile phones and personal televisions, used for mobile television. In the United States, the service powered by this technology was branded as FLO TV. Broadcast data transmitted via MediaFLO includes live, real time audio and video streams, as well as scheduled video and audio clips and shows. The technology could also carry Internet Protocol datacast application data, such as stock market quotes, sports scores, and weather reports. In October 2010, Qualcomm announced it was suspending new sales of the service to consumers. In December 2010, AT&T announced that it will purchase Qualcomm's FCC licenses in the 700 MHz band. FLO TV discontinued service on March 27, 2011. Overview The "FLO" in MediaFLO stood for ''Forward Link Only'', meaning that the data transmission path is one way, from the tower to the device. The MediaFLO system transmitted data on a frequ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Head Start (positioning)
A head start is a start in advance of the starting position of others in the competition, or simply toward the finish line or desired outcome. Depending on the situation, a head start may be inherent, obtained by special privilege, earned through one's accomplishments, or granted mercifully by an opponent. While not guaranteeing success, a head start will increase such chances. In sports In competitive sports, such as a race, a head start refers to a start ahead of other competitors, allowing a shorter distance to the finish line. The idea of a head start may seem unfair. But in some cases, a head start is an advantage that may be earned by one more of the competitors. Also, adults who are racing against children may provide children with a head start, knowing the children are slower, and wanting to allow them a chance to win. In multiple-event or multiple-day competitions, such as the modern pentathlon, the final event may use a head start where the leader of the competition ...
