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: An information reproducing apparatus reproduces one type of information (for example, video information) in synchronous with a plurality of channels of other type of information (for example, audio information) with high copyright protection, and includes a decryption section that decrypts multiplexed stream reproduced from a recording medium, a stream analyzer that analyzes the multiplexed stream which is decrypted to detect first information (video information) contained in the multiplexed stream, a stream conversion section that alters the first information contained in the multiplexed stream which is decrypted, based on an analysis result by the analyzer. The multiplexed stream with altered video information is distributed to second to n-th stream decoders (for example, for achieving a multilingual system).

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 reproduced signal processor comprising sync block detecting means (100), data information generating means (106), first memory means (105), memory writing means (104), memory reading means (109) for parallel reading data of n frames (n is an integer of 2 or more satisfying ?<n) stored in the first memory means (105), and transferring means (112, 1504) for transferring n pieces of transfer data after restructuring n pieces of frame data read out by the memory reading means (109) according to the data information or not restructuring them.

Abstract: A digital signal processing method comprising the steps of: (a) composing, a plurality of first encoded video data and a plurality of second encoded video data; (b) dividing, each of high quality M bits audio channel into audio data of upper L bits and audio data of lower M-L bits; (c) composing a plurality of first basic data and a plurality of second basic data, wherein each of the first basic data have respective audio data of upper “L” bits, and wherein the second basic data have respective audio data of audio data of lower “M-L”; and (d) transmitting the first basic data in a first data bus, and the second basic data in a second data bus.

Abstract: To enable interlacing edge-generating means to be used for a progressive image signal that is separated into lines as two sequences of signals, the present invention comprises a pre-edge processing circuit (11) that executes appropriate pre-edge processing on the progressive image signal separated into lines depending on the condition of each of the two signals, and an edge generating circuit (18, 19) that executes on the two signals after pre-edge processing pre-edge generation processing similar to that for interlacing.
