Television in Hong Kong has two broadcast television networks, TVB and ATV. Launched in 29 May 1957 as Rediffusion Television (RTV), aTV is the first Chinese television station in the world. TVB, launched in 1967, is the territory's first free-to-air commercial station, and is currently the predominant TV station in the territory. Paid cable and satellite television are also widespread. Hong Kong's soap drama, comedy series and variety show productions reach mass audiences throughout the Cantonese-speaking, and even Mandarin-speaking, world. Broadcast media and news is provided by several companies, one of which is government-run. Television provides the major source of news and entertainment for the average family. == Digital television == Although Hong Kong is not required to follow Mainland China's standard, Hong Kong government nevertheless opted to use DMB-T/H (now known as DTMB) as the digital television broadcast standard and the official commencement of digital TV broadcasting began at 7pm on 31 December 2007 as the first digital TV signal transmitter in Tsz Wan Shan went online earlier in December. In October 2007, both broadcasting companies agreed to utilise the MPEG2 video format for simulcasting channels (TVB Jade, ATV Home, TVB Pearl and ATV World); the H.264 format will be implemented for all digital-broadcasting-only channels. For the audio codec, usual DTMB set-top boxes will support MPEG-1 Audio Layer II (MP2) for stereo audio tracks, and Dolby AC-3 for surround sound audio tracks. TVB will also implement the use of MHEG-5 technology for providing interactive features, named "TVB Interactive", and providing a logo for consumers to identify set-top boxes with MHEG-5 middleware support.〔(TVB Interactive logo ).
