NAB2005: Envivio Rolls Out HD MPEG-4 Encoding Systems
is also introducing two new series of MPEG-4 encoding systems for mobile and HD applications this week (see Tandberg item in this issue). The 4Caster Mobile and the 4Coder HD product families are designed to power high quality video services at the lowest possible bit rates. 4Caster Mobile series is a product family of real-time MPEG-4 encoders that optimally distribute audio and video to mobile phone and mobile television subscribers. (The encoding systems are compliant with international mobile delivery standards including 3GPP, DVB-H and ISDB-T.)
Optimized processing produces relatively low bit-rate content, a factor typically sought by mobile operators wanting to enrich their services beyond voice to offer HD and SD, as well as VOD. 4Coder Broadcast series consists of offline MPEG-4 encoders for either HD or SD programming. The systems feature dual-pass encoding with preview and batch modes, MPEG-4 HE AAC audio, and an optimized codec for multiprocessor platforms. The 4Coder series incorporates pre-processing and pre-filtering to deliver optimum audio-video quality at the lowest possible bit rate.
Key features of Envivio encoders also include IP networking, and the ability to deliver interactive multimedia presentations.
