April 23, 2001--Thomcast introduces
Optimux, a revolutionary and patented technology, which enables
bandwidth optimization for the broadcast of live transport streams
with the insertion of interactive data. With this new technology, the
broadcaster is able to offer a bandwidth-on-demand service to its
customers, by guaranteeing a fixed bandwidth or a variable bandwidth
per service.
Optimux permits management of each constant guaranteed data
components and variable guaranteed bandwidth even in a pure variable
statistical multiplex environment. When interactive data - e.g. IP
data, OpenTV(TM), Mediahighway(TM) MHP, ATVEF or private data is
injected into the bandwidth, the remultiplexing of the data may
therefore be optimized to prevent the slow or the too rapid-
downloading of the interactive application.
Before the Optimux technology was made available by Thomcast,
injecting data within a Transport Stream was a compromise between the
desire for guaranteed rates and loosing bandwidth, and saving
bandwidth (with opportunistic injection for instance) and losing
guaranteed rates. Like a classical statistical multiplexer, Optimux
merges the best of the two possibilities by using a min-max window for
each data component. All the bandwidth can then be used with the
guarantee of minimum rates for critical applications.
"This is all about enabling broadcasters to convert bit streams
into dollar streams," states Eric Gourmelen, Manager of the Multimedia
Department at Thomcast. "With our innovative Optimux technology,
broadcasters will be able to offer, and therefore to bill different
type of services to their customers. The services can be for instance
managed between a fixed guaranteed bandwidth, a variable guaranteed
bandwidth or a pure variable without loosing any bits from the
Transport Stream. With Optimux we can really say: Every bit matters!"
Supported Platforms
Optimux is available on existing Thomcast Multimedia products such
as Opal (IP-MPEG2 gateway) or Coral (OpenTV, Mediahighway, DVB-MHP
data broadcast) and the new Multimedia Router platform. It relies
above the OpenMux(R) software remultiplexing kernel.
