Publication number: 20090304352Abstract: 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.Type: ApplicationFiled: April 15, 2009Publication date: December 10, 2009Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Akihiko NAKAO, Kenshi Dachiku

Patent number: 7506221Abstract: An output coding apparatus includes a coder for coding an inputted bitstream to an error correction and/or detection code composed of information bits and check bits; and a bitstream assembling section for assembling an outputted bitstream by inserting a synchronization code at any one of a plurality of synchronization code insertion positions previously determined in the outputted bitstream, arranging the information bits at any desired positions of the bitstream, and by arranging the check bits at positions other than the synchronization code insertion positions in the bitstream. Therefore, when the coding apparatus is combined with a resynchronization method using both an error correction and/or detection code and a synchronization code, it is possible to solve a problem caused by pseudo-synchronization or synchronization-loss pull-out or step-out due to erroneous detection of the synchronization code.Type: GrantFiled: May 5, 2006Date of Patent: March 17, 2009Assignee: Kabushiki Kaisha ToshibaInventors: Yoshihiro Kikuchi, Toshiaki Watanabe, Kenshi Dachiku, Takeshi Chujoh, Takeshi Nagai

Patent number: 7487410Abstract: Methods and systems are provided for decoding. In one exemplary embodiment, the method may include detecting a synchronization code at a position selected from a plurality of synchronization code inserting positions. The plurality of synchronization code inserting positions may be positioned at periodic intervals in an input code string, and the input code string may include a multiplexed code string and information indicative of a delimiter of the multiplexed code string. The information may be arranged just after the multiplexed code string or between the multiplexed code string and a subsequent synchronization code. The method may also include demultiplexing the input code string on the basis of the position of the synchronization code detected by the detecting, to produce kinds of compressed codes. The method may further include decoding the compressed codes to output a reconstructed signal, each of the kinds of compressed codes being a variable length code.Type: GrantFiled: May 12, 2005Date of Patent: February 3, 2009Assignee: Kabushiki Kaisha ToshibaInventors: Yoshihiro Kikuchi, Toshiaki Watanabe, Kenshi Dachiku, Takeshi Chujoh, Takeshi Nagai
