DirecTV has selected the DiviCom MV100 SD encoder from Harmonic for its new MPEG-4 AVC (H.264) based video services.
DirecTV is also using Harmonic's DiviTrackXE statistical multiplexer to dynamically allocate bandwidth to each channel based on the complexity of the video being encoded, allowing the operator to scale channel density. DirecTV will also use Harmonic's NMX Digital Service Manager, a service-oriented video infrastructure monitoring and control system. NMX offers a set of tools to streamline problem detection, analysis and resolution, implement advanced redundancy architectures, automate service and resource scheduling, as well as to facilitate system installation and configuration.
The MV 100 allows operators to select from a range of compression cores--MPEG-2, MPEG-4 AVC or SMPTE VC-1 according to their technical requirements.
DirecTV is currently deploying MPEG-4 compression gear from Tandberg Television as part of its nationwide local HD broadcast channel rollout.
