Envivio 4Caster C42 encoder

0

Multichannel encoder Envivio 4Caster C42 is designed to encode the MPEG-2 TS streams (received at IP-input) to different output formats, thus enabling the efficient delivery of content to receiving equipment of different types: PC, IPTV set-top boxes, and mobile devices. In addition, the encoder can be equipped with one analog input module – to encode the channels from the air or other analog sources.

Envivio 4Caster C42 is a hardware platform with software encoding core. It ensures the opportunity for increased output and extended functionality of the device – by SW update, without any additional cost. At the moment, 4Caster C42 supports multichannel encoding of standard-definition streams. In addition, "Picture in Picture", Internet TV coding (up to VGA resolution), and 3G Mobile TV functions are supported.

 

For IPTV applications, C4 is supplied in two configurations: “Extreme Compression” and “Premium Compression”. Content for Internet TV applications (provided by 4Caster encoder) can be viewed by popular media players, such as: Windows Media Player, QuickTime, and VLC. For mobile applications, the content can be delivered in 3GPP and 3GPP2 format – for viewing at various mobile devices.
