Abstract
The present invention is directed to system(s), method(s), and apparatus for accurate fast forward rate when performing trick play with variable distance between frames. In one embodiment, there is presented a circuit for providing a fast forward video sequence. The circuit comprises a system time clock for providing a time reference, said time reference incremented at a predetermined fast forward rate; a comparator for comparing the time reference with timing information associated with a picture; and a controller for determining whether to display the picture based at least in part on the comparison between the timing information and the time reference.
Claims17
A method for fast forwarding a video sequence, said method comprising:
- incrementing a time reference at a predetermined fast forward rate;
- and
- determining whether to display a picture again from the video sequence based at least in part on a comparison between the time reference and timing information associated with the picture.
A circuit for providing a fast forward video sequence, said video decoder comprising:
- a system time clock for providing a time reference, said time reference incremented at a predetermined fast forward rate;
- a comparator for comparing the time reference with timing information associated with a picture;
- and
- a controller for determining whether to display the picture again based at least in part on the comparison between the timing information and the time reference.
A circuit for providing a fast forward video sequence, said circuit comprising:
- a controller;
- a memory connected to the controller, said memory storing a plurality of instructions executable by the controller, wherein execution of the instructions by the controller causes:
- incrementing a time reference at a predetermined fast forward rate;
- and
- determining whether to display a picture again from the video sequence based at least in part on a comparison between the system clock and the time reference and timing information associated with the picture.
