First Claim
Patent Images
1. A method of processing a multimedia frame comprising a first section received in error, comprising:
- obtaining temporal prediction data corresponding to a first reference frame in a processor;
determining whether the first reference frame is reliable for estimating the first section; and
estimating the first section received in error based on one or more sections other than the first section of the multimedia frame and the first reference frame, if it is determined that the first reference frame is reliable.

Abstract
A method and apparatus of processing a multimedia frame comprising a first section received in error are disclosed. The method comprises obtaining temporal prediction data corresponding to a first reference frame. The method further comprises determining whether the first reference frame is reliable for estimating the first section. The method further comprises estimating the first section received in error based on one or more sections other than the first section of the multimedia frame and the first reference frame, if it is determined that the first reference frame is reliable.
