4View Decoder Product Description

Professional MPEG-4/H.264 Decoder with Digital Output for Media Transport Solutions

Envivio 4View™ D1 is a professional standard definition (SD) MPEG-4 AVC/H.264 Main Profile decoder. The system also supports AVC Baseline Profile as well as ASP and SP video decoding, and MPEG-4 AAC/HE-AAC audio decoding. 4View D1 is ideal for all fixed and mobile professional video contribution and primary distribution applications.

The decoder includes dual Ethernet inputs with optional support for DVB-ASI. The system also offers a choice of transport protocols with support for MPEG-2 TS over IP and Pure IP. Both transport mechanisms can be delivered over UDP and RTP/UDP. For store and forward capabilities the decoder includes an internal hard drive which can be used to receive content files transferred from any standards-based MPEG-4 encoder. Once the files have been stored they can be decoded on command. The 4View D1 is controlled using a comprehensive and intuitive web-based system management interface.

4View D1 is a key component of Envivio media transport solutions and is a companion product to the 4Caster™ Broadcast and Mobile Series of encoders. The professional decoder may also be deployed with any open standards-based SD MPEG-4 encoding system. In addition to high-resolution broadcast applications, 4View D1 supports a non-scaled output option allowing mobile video streams to be displayed in their native resolution. Combined with the Envivio encoders, 4View D1 provides low latency and high network resilience and offers superior video quality at half the bandwidth required by MPEG-2.
