Statistical Multiplexing Solution

Flextream 2.0

Harmonic's Flextream statistical multiplexing solution lets you deliver more channels within the same fixed-bandwidth satellite, cable, or terrestrial connection.

Flextream gives you the unique capability to dynamically share a mixed pool of SD and HD channels using MPEG-2 and MPEG-4 formats, making it an ideal solution for terrestrial as well as satellite networks. With Flextream 2.0, Harmonic has achieved greater efficiency by integrating ancillary services within the multiplexing pool. Flextream 2.0 frees up bandwidth provisioned for the processing of service components such as audio, teletext, subtitling, and closed captioning, allowing it to be reallocated to improve video quality and enables to boost overall statistical multiplexing system performance as well as efficiency while simplifying operations through easier configuration and monitoring.

Flextream 2.0 delivers better bit rate performance and allows greater flexibility of architecture for system deployments involving hybrid statistical multiplexing for all-embracing service delivery, including multi-language audio and multichannel subtitling. Flextream 2.0 addresses most architectures — in particular, those that carry the communication within the statistical multiplexing pools on the video backbone infrastructure itself — to serve as a highly fault-tolerant system.

Flextream 2.0 Features

A Complete Solution

The full featured Flextream supports LAN and WAN architectures, hybrid SD/HD, and a mix of videos encoding standards. And to push performance even further, Flextream 2.0’s capabilities have been extended to include audio, subtitles and data components.

Simplified Operations

Because bitrate is allocated and reclaimed in real time, there is no more need for complex scheduling of multiplexer
configuration changes. Subtitles, audio description and other data components can be simply and automatically inserted when available.

Maximizing Bandwidth Investment

Many satellite transponders or terrestrial multiplexes include a high ratio of null packets simply because fixed provisioning ensures allocation of sufficient bandwidth for data. With Flextream 2.0, fixed bandwidth provisioning is no longer needed. The unused bandwidth is automatically and dynamically reclaimed to improve video quality and potentially add extra channels to the Transport Stream.
