DIRECTV taps Harmonics for MPEG-4 delivery

Harmonic’s 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 has selected Harmonic's DiviCom MV 100 SD encoder for new MPEG-4 AVC (H.264) based video services.

DIRECTV is also using Harmonic’s DiviTrackXE statistical multiplexing solution and NMX Digital Service Manager, a service-oriented video infrastructure monitoring and control system.

The architecture of the MV 100 permits operators to select from a range of compression cores — MPEG-2, MPEG-4 AVC or SMPTE VC-1 — according to their technical requirements. Field-installable software modules allow a transition from one compression technology to another.

Harmonic’s DiviTrackXE closed-loop statistical multiplexing system dynamically allocates bandwidth to each channel based on the complexity of the video being encoded, making it possible to achieve a significant scaling of channel density.

NMX Digital Service Manager offers a set of tools designed to streamline problem detection, analysis and resolution, implement redundancy architectures, automate service and resource scheduling, as well as to facilitate system installation and configuration.
