摘要： Improved scanning of digital video programs is provided for by adjusting scanning rates according to the length of the video program and/or the length of the remaining portion of the video program to be scanned. Shorter video programs are scanned at a slower speed, and longer video programs at a faster speed. In alternate embodiments, scanning speed is based in part on the length of the portion of the video program remaining to be scanned. Thus, when scanning in a video program a forward direction (“fast forward”) when only a given amount of the program remains to be scanned, the scanning speed is slowed. The amount of the program may be determined either according to a fixed length or relative to the length of the entire program. Additionally, in some embodiments, different scanning techniques are used based on the length of the video program being scanned or the length of the video program portion remaining to be scanned.
