| 20090304352 | VIDEO RECORDING AND PLAYBACK EQUIPMENT, VIDEO RECORDING METHOD, VIDEO PLAYBACK METHOD, AND VIDEO RECORDING AND PLAYBACK METHOD - 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. | 12-10-2009 |
| 20100290760 | MOVING IMAGE PLAYBACK APPARATUS - 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. | 11-18-2010 |
| 20110221958 | VIDEO SENDING APPARATUS AND CAPTION REPLACING METHOD - 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. | 09-15-2011 |
| 20110222838 | VIDEO PLAYBACK DEVICE AND VIDEO PLAYBACK 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. | 09-15-2011 |
