Abstract
Presented herein are system(s), method(s), and apparatus for determining the presentation time for a picture without a presentation time stamp. A first and second picture are decoded. The first picture is a reference picture for the second picture. The presentation time for the second pictures is computed as a function of a presentation time and a decode time for the first picture.
Claims15
A method for determining a presentation time for pictures, said method comprising:
- decoding a first picture;
- decoding a second picture, the first picture being a reference picture for the second picture;
- and
- computing a presentation time for the second picture based on a presentation time and a decode time for the first picture.
A circuit for determining a presentation time for pictures, said circuit comprising:
- a processor;
- and
- a memory connected to the processor, said memory storing a plurality of executable instructions, wherein execution of the instructions by the processor causes:
- decoding a first picture;
- decoding a second picture, wherein the first picture being a reference picture for the second picture;
- and
- computing a presentation time for the second picture based on a presentation time and a decode time for the first picture.
A system for determining a presentation time for pictures, said system comprising:
- a video decoder for decoding a first picture and decoding a second picture, the first picture being a reference picture for the second picture;
- a frame buffer for storing the first picture;
- a buffer descriptor structure for storing a presentation time and a decode time for the first picture;
- wherein the video decoder computes a presentation time for the second picture based on a presentation time and a decode time for the first picture.
