Publication number: 20080145021Abstract: In a video recording apparatus which records and reproduces digital TV broadcasting, an I-picture extraction processor that extracts packets containing I-pictures by analyzing a transport stream is arranged. Then, packets containing I-pictures is output, by reading predetermined amount of recorded data from an HDD in which recorded data is stored and by detecting start information and end information of the I-pictures. A stream for special reproduction is output by repeating the above-stated processes. With such arrangement, it is possible, even if data does not contain position information of I-picture, to execute special reproduction such as fast-forwarding reproduction for TV program data that is recorded as an MPEG-formatted transport stream.Type: ApplicationFiled: December 18, 2007Publication date: June 19, 2008Inventors: Satoru Takashimizu, Mitsunobu Watanabe, Satoshi Iimuro
