Patent number: 8170118Abstract: Encoding parameters of picture and higher layers of importance to a number of applications, and encoding parameters of slice and lower layers of no importance to all applications are converted into auxiliary packets inserted respectively into a V-blanking area and an H-blanking area of a video-data signal output by a history-information-multiplexing apparatus employed in a video-decoding system. On the other hand, a video-encoding system extracts back the auxiliary packets superposed on the V-blanking area and the H-blanking area from an input base-band video signal. As a result, a technique of superposing information on data can be changed in accordance with the importance of the information and required information can be fetched with ease.Type: GrantFiled: August 28, 2006Date of Patent: May 1, 2012Assignee: Sony CorporationInventors: Takuya Kitamura, Mamoru Ueda, Katsumi Tahara

Publication number: 20090010334Abstract: A slice decoder control circuit sequentially supplies the parameter of the picture layer and the write pointer of a first slice to a first slice decoder, the parameter of the picture layer and the write pointer of a second slice to a second slice decoder, and the parameter of the picture layer and the write pointer of a third slice to a third slice decoder, and causes the slice decoders to decode the respective parameters and write pointers. On the basis of the input of signals indicating the completion of decoding processing inputted from the slice decoders, the slice decoder control circuit supplies the write pointer of a fourth slice to the second decoder and causes the second slice decoder to decode the write pointer at timing A, and supplies the write pointer of a fifth slice to the third decoder and causes the third slice decoder to decode the write pointer at timing B. Subsequently, the similar processing is repeated until the last slice is decoded.Type: ApplicationFiled: August 25, 2008Publication date: January 8, 2009Inventors: Mamoru Ueda, Koki Kanesaka, Takumi Ohara, Takeshi Yamamoto, Kazuhiro Mizuno, Toshikazu Morita

Patent number: 7292772Abstract: A video decoder reproduces an MP@ML/MPEG-2 video bit stream at an arbitrary speed. When a slice decoder control circuit receives parameters, the slice decoder control circuit sequentially supplies parameters of a picture layer and a write pointer associated with a first slice to a first slice decoder, the parameters of the picture layer and a write pointer associated with a second slice to a second slice decoder, the parameters of the picture layer and a write pointer associated with a third slice to a third slice decoder, so that the slices are decoded by the respective slice decoders. On the basis of signals indicating completion of decoding, received from the first to third slice decoders, the slice decoder control circuit gives commands the first to third slice decoders to decode particular slices.Type: GrantFiled: May 25, 2001Date of Patent: November 6, 2007Assignee: Sony CorporationInventor: Mamoru Ueda
