Harmonic Releases ProMedia Xpress
May 16, 2012
SAN JOSE, CALIF.:
Harmonic announced the release
of the ProMedia Xpress file-based transcoder, the newest addition to the company’s
ProMedia family of software and appliances.
uses Harmonic’s H.264 codec and its new MicroGrid parallel-computing technology.
MicroGrid’s use of multi-core computing eliminates the bottlenecks associated with
traditional transcoding approaches. Combined with the ProMedia Package stream packager,
ProMedia Xpress allows multirate H.264 assets to be encapsulated for target ecosystems
including Apple HTTP Live Streaming, Microsoft Smooth Streaming, Adobe HTTP Dynamic
Streaming, and MPEG-DASH. Because ProMedia Xpress and Package separate the transcoding
and packaging processes, users can transcode an asset once and package it multiple
times, thereby reducing repetitive processor-intensive tasks and easing the need
to accommodate changing delivery standards and protocols.
between ProMedia Xpress and Harmonic’s Omneon MediaGrid shared storage system allows
content to be stored and accessed on the network at high speed, eliminating the
latency associated with copying content to the transcode nodes before transcoding,
and instantly making available transcoded content for downstream operations such
as QC, distribution, delivery or archive.
