According to one embodiment, a video server includes an analyzer and a storage. The analyzer detects a sequence parameter set (SPS) and a picture parameter set (PPS) in a stream of a data file includes picture slices, SPSs and PPSs. The analyzer stores the detected SPS and PPS. When the analyzer detects a first picture slice in a random access unit (RAU) in the stream, the analyzer generates an additional header including all SPSs and PPSs in the stream of the data file, which are stored before detection of the first picture slice. The analyzer inserts the additional header immediately before the RAU. The storage stores the data file in which the additional header is inserted.

Video server and data recording and playback method

A multi-format output device includes decoders to decode first encoded data and second encoded data to generate a first video data having a first-type format with first caption data also having the first-type format, and second video data having a second-type format with second caption data also having the second-type format. A conversion unit converts video data of one format type into video data video data having another format-type. A buffer holds the first video data by the period of time needed for the video data conversion processing. A caption conversion unit delays the caption data for the video data conversion processing time and also converts the caption data of one format type to another format type. A multiplexer outputs the first video data with the first caption data followed by the converted video data with the third caption data having the first-type format.

Multi-format output device, control method for multi-format output device

According to one embodiment, a controller of a multiformat video playback device creates control information including a conversion instruction intended for an input processor, size specification intended for a scaler, and format specification intended for an output processor, and supplies the created control information to the input processor. A first delay section delays the control information supplied to the input processor by one frame, and supplies the delayed control information to the scaler. A second delay section delays the control information supplied to the scaler by one frame, and supplies the resultant control information to the output processor.

Multiformat video playback device and control method thereof

A moving image playback apparatus includes two decoders and one output buffer. In standby, using I-picture in a specified GOP as a reference, a controller causes a storage device to sequentially read first coded image data of the pictures in a first GOP preceding a specified GOP and the pictures up to I-picture in the specified GOP, and causes a first decoder to decode the first coded image data, during which the controller causes the storage device to sequentially read second coded image data of the pictures in the specified GOP and the pictures up to I-picture in a second GOP following the specified GOP, and causes a second decoder to decode the second coded image data. Thereafter, outputs from the first and second decoders are written to the output buffer, and outputted from the output buffer immediately upon start of reverse playback, and moving images are played back.

A reception processor converts an MXF file to internal content data pieces, and converts replacement caption data to internal caption data pieces and then stores the internal content data pieces and the internal caption data pieces in a memory. A separator separates a video data piece, an audio data piece and an ANC data piece from the internal content data piece received from the memory. When a caption replacer receives synchronously the internal caption data piece outputted from the memory and the ANC data piece outputted from the separator, the caption replacer replaces a caption data piece included in the ANC data piece with a replacement data piece in the internal caption data piece. Subsequently, the multiplexer multiplexes the video data piece and the audio data piece outputted from the separator, and the ANC data piece outputted from the caption replacer, and thus outputs an SDI signal.

Video sending apparatus and caption replacing method

A multi-decoder includes a plurality of decoders for different types of coding, an output buffer which stores and outputs the decoded output signal output from the decoders, an output switcher which selectively outputs the decoded output signal of the output buffer, and a controller which determines a coding scheme of the stream based on data of the header area of a stream inputted to each of the decoders, and outputs the stream to the corresponding decoder based on the determination result, and controls the output switcher to switch a decoded output signal of a sender to another decoded output signal, when inputting a stream switching signal.

Multi-decoder and method

A moving image playback apparatus capable of starting within a short time to play back reverse direction moving images is provided. The apparatus includes two decoders and one output buffer. In standby, using I-picture in a specified GOP as a reference, a controller causes a storage device to sequentially read first coded image data of the pictures in a first GOP preceding a specified GOP and the pictures up to I-picture in the specified GOP, and causes a first decoder to decode the first coded image data. Moreover, during the decoding of the first decoder, the controller causes the storage device to sequentially read second coded image data of the pictures in the specified GOP and the pictures up to I-picture in a second GOP following the specified GOP, and causes a second decoder to decode the second coded image data. Thereafter, the controller causes the outputs from the first and second decoders to be written to the output buffer. Thereby, the decoded image data are outputted from the output buffer immediately upon start of reverse playback, and moving images are played back.

According to one embodiment, a data storage apparatus including memory chips includes an error correction encoder, a RAID controller, error detectors and memory units. Each of the memory chips includes a semiconductor memory. The error correction encoder adds an error correction code to an encoded data stream. The RAID controller divides the encoded data stream from the error correction encoder into data blocks. The RAID controller generates a parity data block based on the data blocks. The RAID controller outputs the data blocks and parity data block to the error detectors, respectively. The error detectors add an error detection code to the data blocks and parity data block output from the RAID controller. Each of the memory units includes the memory chips. The memory units write the data blocks and parity data block from the error detectors to the memory chips.

Data storage apparatus and data writing/reading method

According to an embodiment, a memory creates first packet data and second packet data which are identical to the first packet data, and adds the same serial number to the first packet data and the second packet data. The first packet data is supplied to one port of a decoder through one switch unit, while the second packet data is supplied to the other port of the same decoder through the other switch unit. The decoder checks on the first packet data and the second packet data provided with the same serial number, and thereby monitors whether or not an error occurs in the first packet data and the second packet data. Then, the decoder decodes normal packet data selected from the first packet data and the second packet data, and outputs the decoded data to a video switch.

A video recording and playback equipment which plays video data of a program memorized in an MXF file without playback delay is provided. It has a receiver, an analyzer, a playback information table, a program data memory and a decoder. The receiver receives the MXF file which includes the video data and metadata including information about an identification tag to identify the video data and data size of the video data. The analyzer judges whether the data contained in the file is the video data. If it is the video data, the analyzer analyzes a memory location where the video data is memorized in the file and memorize it on the playback information table as playback information, and also memorize the file to the program data memory. Only the video data is played by the decoder from the file based on the playback information.

An input image signal is coded by an encoder to be outputted as a basic code string, and the basic code string is delayed by a code-string delay circuit for a predetermined period of time to be outputted as an additional code string. The basic code string is synthesized with the additional code string by a code-string synthesizer to be outputted as an output code string. Thus, there is provided an image data coding system which can quickly restore data even if the data is lost due to error and in which the increased code amount is less than the cycle refresh and the error correction.
