Video Processing

For many years Harmonic has been at the forefront of variable bit-rate encoding and statistical multiplexing with the goal of consistently maximizing the number of channels per transport stream while maintaining superior picture quality. For both ASI and IP based headend environments, Harmonic offers the most advanced, scalable multiplexing solutions that support either standard definition (SD) or high definition (HD) video pools as well as mixed SD/HD pools.

Harmonic’s DiviTrackIP™ distributed statistical multiplexing further enhances bandwidth efficiency of Electra variable bit-rate (VBR) encoders by allowing bandwidth to be dynamically allocated among geographically dispersed encoders according to complexity of the content.

DiviTrackMX™ statistical multiplexing technology is integrated with the ProStream 1000 stream processing platform and the Ion MPEG-2 encoders, allowing operators to deliver highly efficient VBR services without the need for any additional equipment.
