CableLabs has specified voice quality technology from Global IP Sound as a mandatory codec in its recently released PacketCable 1.1 Audio/Video Codec Specification for multimedia terminal adapters (MTAs) and media gateways.
Global IP Sound’s iLBC (internet Low-Bitrate Codec) is a 13.3 kb/s and 15.2 kb/s codec that will enable equipment manufacturers to satisfy the PacketCable requirement for toll-grade or superior voice quality in Voice-over-Cable systems. Additional PacketCable 1.1 requirements include support for both 20ms and 30ms frame size modes and multi-vendor support.
In addition, GIPS iLBC is already in the final stages of a standardization process as part of the IETF Audio Visual Transport (avt) Working Group.
Texas Instruments has been collaborating with Global IP Sound for more than a year on the implementation of iLBC onto TI DSPs. The companies have recently completed successful interoperability testing in preparation for market launch. http://www.globalipsound.com
- Earlier this month, Broadcom announced that CableLabs had chosen its BroadVoice16 voice compression codec as one of two royalty-free voice codecs for all future PacketCable 1.1 and 1.0 certified and qualified embedded multimedia terminal adapters (EMTAs) and PSTN media gateways beginning in April of 2005, pending successful conclusion of certain conditions such as demonstration of multi-vendor interoperability.
