Description
The Cisco D9859 platform (Figures 1 and 2) extends the distribution options for MPEG-4 Advanced Video Coding (AVC) HD from MPEG-4 only environments to existing MPEG-2 networks. Support for up to eight simultaneous high-definition or standard-definition (SD) channels of decryption and transcoding provides the advantage of density for locations requiring more than just a single channel.
