Patent number: 8077258Abstract: An image display apparatus includes the following elements. An IP converter performs signal conversion processing for converting an interlace signal into a progressive signal including information on interpolated pixels. A frame controller temporally divides an input image frame to generate a plurality of sub-frames. A high-frequency-enhanced sub-frame generator and a high-frequency-suppressed sub-frame generator perform filtering processing on the sub-frames to generate high-frequency-enhanced sub-frames and high-frequency-suppressed sub-frames, respectively. A first output controller alternately outputs the high-frequency-enhanced sub-frames and the high-frequency-suppressed sub-frames. A gain controller adjusts an output level of the sub-frames.Type: GrantFiled: May 7, 2007Date of Patent: December 13, 2011Assignee: Sony CorporationInventors: Masahiro Take, Shoji Kosuge

Patent number: 7266751Abstract: In a data recording method and a data recording apparatus relating to the present invention, ECC blocks using 36 product codes are recorded on 12 tracks through scanning operations performed three times. First of all, first sync-blocks each constituted by adding a C1 parity to the data string of video data constituting an internal encoding calculation data stream are sequentially recorded. When the first sync-blocks are completely recorded, second sync-blocks each constituted by adding the C1 parity to the data string of C2 parity constituting the internal encoding calculation data stream are sequentially recorded. By recording the C2 parity at one time in a later stage, the system delay can be minimized.Type: GrantFiled: April 2, 2004Date of Patent: September 4, 2007Assignee: Sony CorporationInventors: Kaoru Urata, Shoji Kosuge

Patent number: 6507695Abstract: Input terminals to which two types of serial data with similar formats are sent are disposed. Video data sent to the normal dubbing input terminal is data that has not been compressed/encoded. Data sent to the straight dubbing input terminal is data that has been compressed and encoded. Data received from the input terminal includes a sync error flag (error flag for each sync block) that is OR output data of data added by a reproducing VTR and transmission error information. The sync error flag is sent to an ECC encoder through a format converter not through an BRR encoder. An output signal of an ECC encoder is recorded to a magnetic tape by recording heads through a recording driver.Type: GrantFiled: March 19, 1998Date of Patent: January 14, 2003Assignee: Sony CorporationInventors: Fumiaki Henmi, Tetsuo Kani, Yoshihiro Murakami, Takao Inoue, Shoji Kosuge, Minoru Kawahara, Makoto Toyoshima

Patent number: 6438316Abstract: A line number LN is extracted from serial data corresponding to BTA S-004 standard. The line number LN is placed as LN0 and LN1 to each of a luminance signal Y and color difference signals Pr/Pb of a 4:2:2 signal. The 4:2:2 signal is converted into a 3:1:1 signal by a bandwidth-compressing means. In addition, the 3:1:1 signal is re-arranged to two-channel signals Ch0 and Ch1 with the same format at a transmission rate of 46.40625 MHz. Thereafter, the, signals are processed at the transmission rate of 46.40625. The line number LN is placed as LN0 and LN1 at the beginning of one horizontal interval.Type: GrantFiled: December 1, 1998Date of Patent: August 20, 2002Assignee: Sony CorporationInventors: Fumiaki Henmi, Tetsuo Kani, Yoshihiro Murakami, Takao Inoue, Shoji Kosuge, Minoru Kawahara, Makoto Toyoshima, Kenji Uehara

Patent number: 6192182Abstract: A digital video signal of one frame is recorded as diagonal tracks on a magnetic tape by four recording heads. One frame is recorded as six segments (twelve tracks). Adjacent tracks is reverse azimuths. In each track of even segments, an auxiliary data sync block is recorded at the last position of a video sector v1. In each track of odd segments, an auxiliary data sync block is recorded at the beginning position of a video sector v1. Since an auxiliary data sync block is recorded at spaced positions on a tape, it can be prevented that an auxiliary data cannot be read at all on a tape scrached in the longitudinal direction.Type: GrantFiled: November 27, 1998Date of Patent: February 20, 2001Assignee: Sony CorporationInventors: Minoru Kawahara, Shoji Kosuge, Kenji Yamasaki
