20100290537 | DYNAMIC IMAGE STREAM PROCESSING METHOD AND DEVICE, AND DYNAMIC IMAGE REPRODUCTION DEVICE AND DYNAMIC IMAGE DISTRIBUTION DEVICE USING THE SAME - There are included: an extraction unit that extracts a first bit stream of a picture that is decodable by itself and a second bit stream of a picture whose image data part is decodable by itself but a part other than the image data part is not decodable by itself from a coded bit stream of a moving image; and a conversion unit that converts the second bit stream extracted by the extraction unit into a third bit stream of a picture that is decodable by itself, the first bit stream of the picture extracted by the extraction unit and the third bit stream being arranged and output in order of extraction or in reverse order to that of extraction. | 11-18-2010 |
20110268192 | MOVING IMAGE DECODING DEVICE, MOVING IMAGE DECODING METHOD, AND PROGRAM - There are provided an analysis unit that analyzes an input bit stream to output first intermediate data and analysis information, a conversion rule storage unit that stores a conversion rule, according to which an error-detected bit stream included in the analysis information output from the analysis unit or a bit stream including reference information to an image used for a method not supported by a decoding unit is converted into a bit stream decodable by the decoding unit, and a conversion unit that converts the analysis information into second intermediate data according to the conversion rule, as well as the decoding unit that decodes the first intermediate data and the second intermediate data output from the analysis unit and the conversion unit. Thus, even when the decoding unit does not cope with specific information included in the analysis information, the decoding unit is able to stably perform a decoding procedure. | 11-03-2011 |
20130083858 | VIDEO IMAGE DELIVERY SYSTEM, VIDEO IMAGE TRANSMISSION DEVICE, VIDEO IMAGE DELIVERY METHOD, AND VIDEO IMAGE DELIVERY PROGRAM - A transmission device includes: a bit stream storage unit for transforming video signals into a plurality of bit streams having different bit rates in advance and storing those; a receiving device information acquisition unit which acquires information pertaining to a receiving device from the receiving device; a selection control unit which determines the bit rate and the variable-length encoding method for the bit stream transmitted to the receiving device; and a transmission unit which transmits, to the receiving device, the bit stream having the bit rate and the variable-length encoding method determined by the selection control unit. The selection control unit determines the bit rate and the variable-length encoding method so that the amount of the video image data before being subjected to variable-length encoding is at the maximum and so that the bit rate is within the maximum bit rate which can be processed by the receiving device. | 04-04-2013 |
