Abstract: A video reproduction apparatus includes audio data reading unit for reading audio data in a second file; video data reading units for reading video data in a first file; audio decoding unit for generating an audio signal from the audio data read by the audio data reading unit; video decoding unit for decoding the demultiplexed video data; and read controlling unit for controlling the audio data reading unit and the video data reading unit. The read controlling unit reads the first file using a band other than a band required to read the second file, and instructs to output skipped video data.

Abstract: A video recording device comprises an input unit, an encode unit, and an output unit. A plurality of channels of video data is inputted to an input unit. An encode unit is configured to adjust the GOP structure and frame size to be the same in the plurality of channels of video data to the input unit, and compress and encode the plurality of channels of video data inputted at a variable bit rate. An output unit is configured to output the plurality of channels of video data compressed and encoded by the encode unit.

Abstract: In recording materials of a video program or the like, the video materials are efficiently and optimally acquired so that processing steps in and after an editing step subsequent to a recording step can be reduced. A recording support information (metadata) on a schedule of and a performer for an imaging operation, and the like, which are determined in advance is recorded in a first recording medium 16 by a program constitution input device 100. The first recording medium 16 is inserted in to an imaging device 200, materials to be recorded are classified and confirmed based on the metadata, and the materials which can constitute a desirable program as potentially as possible are acquired in the recording operation.

Abstract: An object of the present invention is to reduce a possibility of existence of a plurality of identical file names in files which are created by a plurality of apparatuses. This is accomplished using a file name generation apparatus having an UMID generation unit (12) generating a globally unique identifier, and a file name generation unit (14) generating a file name including the globally unique identifier generated by the UMID generation unit (12).

Abstract: A camera recorder that is capable of recording and reproducing a large volume of image data at a high speed and a data recording medium that can be used for the camera recorder are provided. The camera recorder includes a camera portion 1 and a recording portion 2 for recording image data picked up by the camera portion 1. The recording portion 2 includes an interface portion 3 for receiving the image data from the camera portion 1, a plurality of memory cards 50 to 53 for storing the image data, and a controlling portion 4 for controlling writing of the image data to the memory cards 50 to 53. The memory cards 50 to 53 are constituted by a flash memory, and the controlling portion 4 divides the image data received from the camera portion 1 via the interface portion 3 into blocks having a data size that is an integral multiple of a recording block of the flash memory, and records the image data to the memory cards 50 to 53 in parallel.

Abstract: A program distribution system stores compressed program information created by compressing a plurality of consecutive frame images. Then, after receiving segment information that indicates a specific segment of frame images to be distributed, the system produces a plurality of decompressed frame images by decompressing a section of the compressed information that corresponds to the segment of frame images indicated by the segment information. Next, the system performs inter-frame compression on the plurality of decompressed frame images, thus producing a new stream of compressed information that is then transmitted as distribution program.
