ABSTRACT:
A system and method for personal video recording (PVR) is provided for recording digitally encoded streams, and for playing back and decoding the recorded streams. The PVR system may receive the digitally encoded streams from a digital cable box or a network server. The system enables trick modes including fast forward and reverse mode displays at various speeds. The system an method for PVR may also be applied to digitally encoded streams without I-pictures, such as, for example, progressive refresh streams or HITS streams. Reverse decode and display may be implemented by starting at a suitable entry point, decoding quickly up to the point of the desired picture, and displaying the result, and repeating the process. Index tables of entry points may be used for proper operation in some modes where the entry points are entry pictures (E-pictures) which start a pattern of progressively refreshing I-slices.
