Patent number: 9906817Abstract: Coding circuitry may implement an indexed set of color values that stores color values for a neighbor pixel group. The coding circuitry may obtain a current pixel group for coding. The coding circuitry may code the current pixel group using the indexed set of color values when an indication that there is a compression advantage to coding using the indexed set of color values is present within an input stream. When the indication is not present, the coding circuitry may code the current pixel group using another coding technique.Type: GrantFiled: May 25, 2016Date of Patent: February 27, 2018Assignee: AVAGO TECHNOLOGIES GENERAL IP (SINGAPORE) PTE.

Patent number: 9883180Abstract: A system adjusts the quantization parameter used to encode an image sample (e.g., pixel component). The system accesses a quantization parameter for encoding a current image pixel from an implicit rate control and obtains a measure of another image sample within a particular distance from the sample. When the measure meets a predetermined criterion, the system adjusts the quantization parameter, encodes the pixel after adjusting the quantization parameter, and explicitly indicates the adjusting of the quantization parameter to a decoding system.Type: GrantFiled: October 2, 2013Date of Patent: January 30, 2018Assignee: AVAGO TECHNOLOGIES GENERAL IP (SINGAPORE) PTE.

Patent number: 9813711Abstract: A system implements a hybrid coding mode. The hybrid coding mode may implement a transform to decompose an input stream into frequency components. The frequency components may include frequency bands such as those resulting from a wavelet transform. The frequency components may have associated coefficients which may be determined via the transform. The hybrid coding mode may also implement a predictor-based coding mode. A predictor-based coding mode uses a set of values as predictors for another set of values. The hybrid mode may be implemented by using predictor-based coding to code a portion of the coefficients. For example, a coefficient may be used as a predictor for another coefficient of same frequency component. In some implementations, dynamic selection between a hybrid coding mode and a point coding mode may be used.Type: GrantFiled: June 12, 2014Date of Patent: November 7, 2017Assignee: AVAGO TECHNOLOGIES GENERAL IP (SINGAPORE) PTE.

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.

Patent number: 9363517Abstract: An encoder may implement an indexed color history that stores color values for previously encoded pixels. The encoder may obtain a current pixel or current group of pixels for encoding and determine whether to encode the current pixel using the indexed color history. In doing so, the encoder may compare a color value of the current pixel with color values of the previously coded pixels to determine whether the current pixel is sufficiently similar to a previously coded pixel color value, e.g., by satisfying one or more similarity criteria. When the similarity criteria are satisfied, the encoder may encode the current pixel as an index value referencing the entry in the indexed color history storing a color value that satisfies the similarity criteria. When the similarity criteria are not satisfied, the encoder may encode the current pixel using another encoding method or technique.Type: GrantFiled: February 17, 2014Date of Patent: June 7, 2016Assignee: Broadcom CorporationInventors: Alexander Garland MacInnis, Frederick George Walls

Publication number: 20150143450Abstract: A system for compositing images in a compressed bitstream can include memory and first and second modules. The first module can be configured to receive images and corresponding position information that indicates positions of the images in a composite image, determine pixels of the images that will be occluded in the composite image, and store, at memory locations of the memory, pixels of the images that will be visible in the composite image. The second module can be configured to receive the position information, retrieve, from the memory locations, the visible pixels of the images, determine the images corresponding to the visible pixels based at least on the memory locations, and generate the composite image by arranging the visible pixels based at least on the position information. In one or more implementations, the visible pixels can be compressed before being stored in memory and decompressed after being retrieved from memory.Type: ApplicationFiled: January 3, 2014Publication date: May 21, 2015Applicant: BROADCOM CORPORATIONInventors: Jaewon SHIN, Brian Francis SCHONER, Frederick George WALLS

Patent number: 8879896Abstract: A method and apparatus are disclosed for facilitating efficient operation of trick modes in a personal video recording (PVR) system. Stream-navigation data from a data stream is captured and pre-processed to generate a frame-correlated NAV table comprising one entry for each frame within the data stream, during recording of the data stream. The stream-navigation data comprises start code data, content rating data, and conditional access data that is embedded in the data stream. During playback of the data stream in a user-selected trick mode, the frame-correlated NAV table is used to generate command packets that are sent to a data decoder along with selected frames of the data stream. The selected frames are decoded based on information in the command packets and certain selected frames may be displayed as part of the trick mode.Type: GrantFiled: July 30, 2010Date of Patent: November 4, 2014Assignee: Broadcom CorporationInventors: Frederick George Walls, David M.
