Patent number: 7012964Abstract: Data indicative of a transfer mode of a transmission packet may be inserted into a payload portion contained in a serial digital transfer interface (SDTI) transmission packet. Also, data indicative of a timing mode of the transmission packet may be inserted into this payload portion. As the transfer mode, there may be provided a synchronous transfer mode and an isochronous transfer mode in addition to an asynchronous transfer mode. A timing mode may prescribe a timing mode in which a transmission packet may be transferred in synchronism with a field of a transmission frame. There may be provided a normal mode using a first field, an advanced mode using a second field and a dual mode using both fields. Depending upon the manner in which the timing mode is set, a system delay between the transmission and the reception can be minimized.Type: GrantFiled: April 16, 1999Date of Patent: March 14, 2006Assignees: Sony Corporation, Sony United Kingdom LimitedInventors: Hiroshi Nakano, Yasuo Iwasaki, Yoshihiro Murakami, Tetsuya Iwamoto, Katsumi Tahara, Hitoshi Sakamoto, James Hedley Wilkinson

Patent number: 6308007Abstract: A recording and reproducing device comprises a plurality of hard disks H1 through Hp, an error checker 12 for detecting write errors produced in the respective hard disks H1 through Hp, a memory 13 for storing therein a logical address for the hard disk H3 from which the write error is detected, and a computing unit 14 for recovering data to be recorded on the write error-detected hard disk H3, based on data recorded on other hard disks H1, H2 and Hp from which no write errors are detected. When the logical address for the write error-detected hard disk H3 is designated, the post-recovery record data is outputted. According to this, since the write error of each hard disk, which has occurred upon writing, can be automatically corrected, the present device can be continuously activated without missing continuity for a request for recording and reproduction of video/audio data.Type: GrantFiled: December 4, 1998Date of Patent: October 23, 2001Assignee: Sony CorporationInventor: Yasuo Iwasaki

Patent number: 6259386Abstract: This invention relates to data input/output apparatus and the like, which are suitable to be applied to an AV server. As nonlinear accessible storage medium, there is provided with HDD array device (13). When a controller (11) of an AV server (10) receives a command for reproducing data from a minimum of two discontinuous areas in the HDD array device (13) in a first order, the HDD array device (13) then puts the command in an order such that a period of time for access is minimal to reads the data so that the read data are rearranged in the first order to be outputted through decoders (15) to (18). Thereby, the efficiency of data transfer is improved without complications.Type: GrantFiled: April 10, 2000Date of Patent: July 10, 2001Assignee: Sony CorporationInventors: Hiroyuki Miyawaki, Takanobu Kondo, Yasuo Iwasaki, Hisao Tanaka

Patent number: 6198876Abstract: A data recording/reproducing apparatus in which plural disc-shaped recording/reproducing means are run in parallel. The apparatus is designed for avoiding the risk of the write/readout unit being changed in size to lower the transfer rate to raise the cost brought about by changing the number of the disc-shaped recording/reproducing means. A disc array unit 11 accesses video data of 163840 bytes equal to 40 times as many as 4096 bytes and audio data of 8192 bytes equal to twice as many as 4096 bytes to a data driving unit 11D made up of seven HDDs with a size of, for example, 3584 bytes. An accessing control unit 12 controls data accessing to the disc array unit 11. A data adjustment unit 25 appends a volume of nonsensical data (padding data) equal to a multiple of 3584 bytes at the time of recording, while taking out data excluding the padding data during reproduction in terms of 4096 bytes as a unit.Type: GrantFiled: May 30, 1997Date of Patent: March 6, 2001Assignee: Sony CorporationInventors: Yasuo Iwasaki, Shogo Suzuki, Makoto Ogura
