Patent number: 9852771Abstract: Disclosed are various embodiments that facilitate recording to a storage medium in a personal video recorder (PVR) system. In one embodiment, a transport stream is received. The transport stream is stored into a memory. An index table is generated that provides information for locating particular frames recorded in the memory.Type: GrantFiled: February 28, 2014Date of Patent: December 26, 2017Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Jason Demas, Marcus Kellerman, Sandeep Bhatia, Srinivasa Mogathala Prabhakara Reddy, Xuemin Chen, Vijayanand Aralaguppe, Girish Raghunath Hulmani, Pramod Chandraiah, Ghanashyam Ananthamurthy Bailwal

Patent number: 9380337Abstract: Command packets for a personal video recorder that provides for a transport stream (TS) that contains data and also includes a transport packet (TP)/TS formatted command packets. The TP/TS formatted command packet may be communicated between any number of devices, including multiple chips, multiple boards, and multiple processors. A decoder is able to decode the TP/TS formatted command packet and to perform the appropriate operation on data portions of the TS. When a TS is provided to a device not having the capability to perform the proper decoding of the TP/TS formatted command packet, that particular packet may be deemed as being unidentified (or unknown) adaptation field data. Alternatively, the packet may be identified as being corrupted data and/or irrelevant data.Type: GrantFiled: September 24, 2010Date of Patent: June 28, 2016Assignee: Broadcom CorporationInventors: Jason Demas, Sandeep Bhatia, Marcus Kellerman, Girish R. Hulmani, Srinivasa Mogathala Prabhakara Reddy, Arun Gopalakrishna Rao, Xuemin Chen, Frederick George Walls

Patent number: 9344725Abstract: Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. Error concealment of MPEG data may take place within various components within playback, recording, reading and writing data systems. The error concealment may be provided within existing systems whose components may not be capable of accommodating errors within MPEG data. In certain embodiments, the available data that contain no errors is maximized to conceal those portions of the data that do include errors.Type: GrantFiled: May 20, 2013Date of Patent: May 17, 2016Assignee: BROADCOM CORPORATIONInventors: Jason C. Demas, Sandeep Bhatia, Xuemin “Sherman” Chen, Srinivasa Mogathala Prabhakara Reddy, Girish Raghunath Hulmani, Marcus Kellerman, Ramanujan Valmiki, Lakshmikanth Pai, Pramod Chandraiah, Mahadevan Sivagururaman, Glen A.

Patent number: 8488665Abstract: Presented herein is a system and method for reducing the total size of the frame buffer portion of a decoding circuit. The reduction in size is possible because first portions of B-pictures are displayed while second portions occurring later in the raster order are decoded. The foregoing allows the second portions occurring later in the raster order to overwrite third portions of the picture that have already been displayed. As a result, the frame buffer for providing the frame from a decoder to the display engine need only store the portion that is being displayed and the portion that is being decoded.Type: GrantFiled: June 25, 2003Date of Patent: July 16, 2013Assignee: Broadcom CorporationInventors: Srinivasa Mogathala Prabhakara Reddy, Sandeep Bhatia, Srilakshmi Dorarajulu

Patent number: 7508874Abstract: Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. The present invention is operable to perform error concealment of MPEG data within various components within playback, recording, reading and writing data systems. The present invention is operable within existing systems whose components may not be capable of accommodating errors within MPEG data. Whereas prior art systems typically cannot deal with any corruption without either losing the data or suffering some operational failure, the present invention is able to conceal these errors and to continue decoding and presentation of the MPEG data. In certain embodiments, this involves maximizing the available data that contain no errors to conceal those portions of the data that do include errors. The present invention is operable to accommodate various layers while performing error concealment, including the MPEG transport stream layer, the video layer, and the audio layer.Type: GrantFiled: January 29, 2002Date of Patent: March 24, 2009Assignee: Broadcom CorporationInventors: Jason C.
