Envivio's 4Caster C4 encoders are being used in trials in Shanghai that combine AVS video encoding with China's standard for digital terrestrial television broadcasting for set-top boxes.

This is the first large scale evaluation of AVS with the DTMB (GB 20600-2006) Digital Terrestrial Media Broadcasting standard to take place in China. Full commercial roll out of digital terrestrial TV services based on a combination of the two standards is expected to begin later this year.

The three month long trial broadcasts were organized and managed by Shanghai Oriental Pearl Company Limited. AVS streams encoded using the Envivio 4Caster C4 were broadcast using the DTMB standard and then decoded by set-top boxes powered by Shanghai Longjing AVS chipsets. The Chinese government has made the roll out of these services a priority in its 11th Five-Year Plan for the development of broadcast and entertainment technology.
