Patent number: 8626966Abstract: Systems and methods and computer program products are disclosed to determine the source data rate even in cases where the sink device is not directly coupled to the source device. A method includes, forming a logical channel from a source device to a sink device where the logical channel is configured to carry the source data stream and one or more rate parameters. The rate parameters relate a data rate of the source data stream to a data rate of the logical channel. Another method includes, detecting a logical channel in a received data stream where the logical channel includes the source data stream, recovering one or more rate parameters from the received data stream, determining a data rate of the logical channel, and determining the data rate of the source data stream based on the data rate of the logical channel and the one or more rate parameters.Type: GrantFiled: March 23, 2012Date of Patent: January 7, 2014Assignee: ATI Technologies ULCInventors: Nicholas J. Chorney, Collis Q. Carter

Patent number: 8589770Abstract: Control symbols taking the form {k1-k2-k2-k1} are inserted in a serial stream including m bit data words. k1 and k2 are each predefined m bit control words differing from the m bit data words. The Hamming distance between k1 and k2 is at least 2. Such control symbols may be robustly detected in the presence of a one bit error in the symbol, or a data word immediately preceding or following the symbol. The m bit words may be 8B/10B encoded data, or defined control words. The control symbols may be used for data delineation, stream synchronizaiton, transmitter/receiver synchronization or for other control signalling.Type: GrantFiled: February 26, 2008Date of Patent: November 19, 2013Assignee: ATI Technologies ULCInventors: Collis Q. Carter, Nicholas J. Chorney, James R. Goodman

Publication number: 20120314777Abstract: A method and apparatus are described for generating a display data stream for transmission to a remote display. A display control unit in a processor is configured to multiplex the outputs of a plurality of display controllers to generate a video data stream. A video compression engine (VCE) in the processor receives the video data stream directly from the display control unit without having to go through an external memory or an external display interface. The VCE compresses the video data stream, and optionally encrypts the video data stream. In one embodiment, audio and video data streams may be synchronized into a multiplexed, (and optionally encrypted), audio/video stream before being forwarded for transmission to a remote display. In another embodiment, separate audio and video streams (optionally encrypted) may be forwarded for transmission to the remote display.Type: ApplicationFiled: June 13, 2011Publication date: December 13, 2012Applicant: ATI TECHNOLOGIES ULCInventors: Lei Zhang, Collis Q. Carter, David I. J. Glen

Publication number: 20120047526Abstract: System and method for mapping audio and video streams from an audio/video (AV) source to respective ones of a plurality of AV sinks. In accordance with one or more embodiments, the audio and video playback and content protection capabilities of each one of the AV sinks are determined based on AV data received via a video channel interface from each one of the AV sinks. Also determined are the audio and video streams available from the AV source. Respective ones of the audio and video streams available from the AV source are mapped to each one of the AV sinks in accordance with their audio and video playback and content protection capabilities.Type: ApplicationFiled: August 20, 2010Publication date: February 23, 2012Applicant: ATI Technologies ULCInventors: Syed A. Hussain, Collis Q. Carter, Gabriel L. Abarca

Publication number: 20100260296Abstract: Systems and methods for synchronizing a source and sink device are disclosed. A sink device can efficiently determine the source data rate even in cases where the sink device is not directly coupled to the source device. A method for transmitting a source data stream from a source device to a sink device includes, forming a logical channel from a source device to a sink device, where the logical channel is configured to carry the source data stream, and one or more rate parameters. The rate parameters relate a data rate of the source data stream to a data rate of the logical channel.Type: ApplicationFiled: April 12, 2010Publication date: October 14, 2010Applicant: ATI Technologies ULCInventors: Nicholas J.
