Abstract
A method for decoding pictures from a digital video bit-stream includes providing a first buffer and a second buffer being overlapped with the first buffer by an overlap region; decoding a first encoded picture from the bit-stream and storing a corresponding first picture into the first buffer; and decoding a second encoded picture from the bit-stream according to the first picture being stored in the first buffer, and storing a corresponding second picture into the second buffer. By overlapping the first buffer and the second buffer, overall buffer memory requirements when decoding the pictures are moderated.

A method for decoding pictures from a digital video bit-stream, the method comprising:
- providing a first buffer and a second buffer being overlapped with the first buffer by an overlap region;
- decoding a first encoded picture from the bit-stream and storing a corresponding first picture into the first buffer;
- and
- decoding a second encoded picture from the bit-stream according to the first picture being stored in the first buffer, and storing a corresponding second picture into the second buffer.
A digital video decoder system comprising:
- a first buffer;
- a second buffer being overlapped with the first buffer by an overlap region;
- and
- a picture decoder for decoding a first encoded picture from the bit-stream and storing a corresponding first picture into the first buffer;
- and decoding a second encoded picture from the bit-stream according to the first picture being stored in the first buffer, and
- storing a corresponding second picture into the second buffer.
A method for decoding pictures from a digital video bit-stream, the method comprising:
- providing a first buffer;
- providing a second buffer being overlapped with the first buffer by an overlap region;
- receiving bits from the digital video bit-stream;
- decoding a first encoded picture from the bit-stream and storing a corresponding first picture into the first buffer;
- storing bits from the bit-stream corresponding to at least a portion of the first encoded picture;
- decoding a second encoded picture from the bit-stream according to the first picture being stored in the first buffer, and storing a corresponding second picture into the second buffer;
- redecoding the stored bits to restore at least a portion of the first picture in the first buffer;
- and
- decoding a third encoded picture from the bit-stream according to the first picture being stored in the first buffer.
