Title:
METHOD AND APPARATUS FOR DATA TRANSMISSION OVER AN AC-97 PROTOCOL LINK
Document Type and Number:
WIPO Patent Application WO2002030083
Kind Code:
A3
Abstract:
An audio Encoder/Decoder (AC)-97 protocol link is used for concurrent data communication between AC-97 protocol devices and non-AC-97 protocol devices. The tag data 502 in an AC-97 data frame is used to select specific CODECs 203, 204, 205 and to determine which data time slors to ignore or accept. Since telephone voice and data communication uses only the Tag data 502 and one other of the data frame time slots, eleven slots are available for communication using non-Ac-97 protocol devices concurrent with telephony communications. Ethernet, Home Phoneline Network Alliance (HPNA), Attachment Unit Interface (AUI) are some of the data communication protocols that may be employed using embodiments of the present invention. An AC-97 data communication controller 201 may modified with addtional logic and control lines to support additional features of non-AC-97 protocol devices.
