Abstract: An encoding method includes controlling recording of frame-position information representing the position of a frame in a video stream, and controlling recording of unit-region-position information representing the position of a unit region serving as a processing unit used when the video stream is decoded.

Abstract: With a decoding method for decoding an encoded stream using a predetermined storage region where input of reproduction information indicating an reproduction state of the encoded stream is received, reference picture information indicating a reference picture necessary for performing decoding processing of a relevant picture in the encoded stream is obtained, based on the reproduction information input by the reproduction information input processing, whether the reference picture is stored in a predetermined storage region is determined, based on the reference picture information obtained by the reference picture information obtaining processing, the reference picture not stored in the storage region is obtained from the encoded stream and decoded, and storage thereof to the storage region is controlled, and the reference picture stored in the storage region is used to perform decoding processing of the relevant picture in the encoded stream, thereby generating image data which is stored in the storage regio

Abstract: An apparatus to be controlled has a storage and information relating to the free storage space of the storage. A control apparatus for recording information in the storage of the apparatus to be controlled by controlling the apparatus to be controlled acquires the information relating to the free storage space of the storage.

Abstract: With an information processing method for generating information utilizable for decoding a bit stream, a forward prediction encoded frame of the bit stream is decoded, the decoded forward prediction encoded frame is subjected to intra-frame encoding, the bit stream is analyzed, and attribute information is generated that is utilizable for decoding the bit stream based on the encoded information relating to the encoded data generated by encoding and the analysis results obtained by the analyzing.

Abstract: A control command attaching the same identifier to related commands is input from an application to an AV data processing control device. Further, a command for linking this identifier and a trigger generated by a contact input-1 is input. When the contact input-1 is generated, all control commands containing the identifier are executed. Further, when the link of the contact input-1 and the identifier of the control command is invalidated, even if the contact input-1 is generated, none of the linked control commands are executed. The execution of the control commands is carried out by controlling the controlled devices by the IDCs.

Abstract: A system for compiling a computer program to implement parallel image processing on a computer having a plurality of arithmetic processors. The program is analyzed to determine whether it contains a parallel image processing identifier, and if so, a plurality of parallel image processing execution codes are generated for use by the arithmetic processors. Thereby, allowing image processing to be conducted at an increased speed.

Abstract: A system for performing parallel processing of images. The image data to be processed is supplied to multiple arithmetic processors by a data supply control unit. Each of the processors operates on a portion of the data to produce a multiple of partial image processing results, and the partial results are integrated to form a final result. Thereby, allowing image processing to be conducted at an increased speed.

Abstract: An information signal transmission device in which information signals are transmitted to requesting parties responsive to requests made by plural requesting parties. The signals of the leading end of the information signals are pre-stored in a versing-up memory and, when a request is made by a requesting party, an output signal of a buffer memory unit for time axis expansion is transmitted to such requesting party after an output signal of the versing-up memory unit is transmitted to such requesting party.
