CableLabs Seeks More Sound for PacketCable
By Karen Brown -- Multichannel News, 5/15/2002 8:29:00 AM
Cable Television Laboratories Inc. is putting out a call to add more sound to the PacketCable interface specifications.
The Louisville, Colo.-based cable-technology consortium has issued a request for proposals for a royalty-free audio codec as an addition to the PacketCable specification.
Audio codecs convert analog voice into packets for digital transmission, then reconvert them back into analog for input into voice and media receivers.
So far, PacketCable recognizes three audio codecs for device manufacturers to use --G.711, which is mandatory, and optional G.728 and G.729E.
The PacketCable initiative seeks to create guidelines for interoperable Internet-protocol-based multimedia devices -- ranging from gaming devices to voice and videoconferencing systems -- that can tap into two-way cable networks.
Companies answering the codec call will have until June 7 to notify CableLabs of their intent, with final submissions due June 28.
Interested companies can contact Venkatesh Sunkad at 303-661-3887 or electronic mail, v.sunkad@cablelabs.com.
