CableLabs Requires Broadcom's BroadVoice16 for PacketCable VoIP

8/5/2004 - Broadcom Corporation (Nasdaq: BRCM), a leading provider of highly integrated semiconductor solutions enabling broadband communications, announced that CableLabs has chosen the Broadcom® BroadVoice16TM voice compression codec as one of two royalty-free voice codecs for all future PacketCableTM 1.1 and 1.0 certified and qualified embedded multimedia terminal adapters (EMTAs) and public switch telephone network (PSTN) media gateways beginning in April of 2005, pending successful conclusion of certain conditions such as demonstration of multi-vendor interoperability. A mandatory voice compression codec in PacketCable products provides cable operators with universal toll-quality voice compression for Voice over Internet Protocol (VoIP) telephony services over cable.

The BroadVoice16 solution was selected in response to a request for proposal (RFP) and an exhaustive analysis by CableLabs to specify a required toll-quality voice compression codec for PacketCable VoIP systems. Prior to the new codec requirements, toll-quality voice compression codecs within the PacketCable specification were optional, due mostly to relatively complex and expensive royalty agreements frequently associated with the use of ITU-based voice compression codecs.

The BroadVoice16 solution is a low-bit rate voice compression codec designed for toll-quality VoIP networks. A codec is a compression/decompression algorithm that reduces the number of bytes consumed by large files and multimedia traffic. In VoIP applications, a codec minimizes the data rate of a voice call over an IP network. The BroadVoice16 solution's advanced compression techniques reduce the bandwidth requirements of VoIP service by over 50 percent, providing cable operators with up to double the call capacity while simultaneously decreasing network infrastructure costs.

"We are very pleased with the performance and voice quality that can be achieved by using the BroadVoice16 voice codec," said Steve Craddock, Senior Vice President of New Media Development at Comcast and Chairman of the CableLabs PacketCable business team. "We believe that the BroadVoice16 solution will be used extensively by cable operators as new cable VoIP services roll out."

"BroadVoice16 is the culmination of over four years of research and development in perfecting the ideal advanced voice compression solution for VoIP applications, thereby aiding cable operators in increasing their respective market share in the rapidly growing VoIP telephony market," said Dan Marotta, Group Vice President of Broadcom's Broadband Communications Business Group. "With CableLabs selecting the BroadVoice16 solution for all PacketCable certifications and qualifications, Broadcom is poised to develop advanced and uniquely competitive silicon solutions along with reference designs that will enable higher voice quality services for the cable VoIP marketplace."

PacketCable is a CableLabs-led initiative aimed at developing interoperable interface specifications for delivering advanced, real-time multimedia services over two-way cable systems. Built on top of the industry's highly successful cable modem infrastructure, PacketCable networks use IP technology to enable a wide range of multimedia services, such as VoIP telephony, multimedia conferencing, telecommuter services and other integrated multimedia applications.

About BroadVoice Voice Compression Codec
The BroadVoice voice compression codec is the industry's first IP telephony codec engineered from the ground up, offering low complexity, small size, short delay and very high toll-grade voice quality. These advantages of BroadVoice translate into more cost-effective VoIP products since the amount of silicon hardware required to provide advanced VoIP services can be greatly reduced.

Broadcom offers the BroadVoice solution in two versions: BroadVoice16 and BroadVoice32, supporting standard and enhanced telephony services respectively. BroadVoice16 is a 16 Kilobit per second (Kbps) voice codec that provides standard toll-quality telephone service at a greatly reduced 16 Kbps rate versus the standard 64 Kbps G.711. This reduced bit rate increases the number of lines a broadband cable VoIP telephony network can service by more than 100 percent. BroadVoice32 is a 32 Kbps voice codec that provides enhanced quality telephone service approaching natural voice or CD quality.
