Abstract
Aspects of a system and method for processing video data may comprise, for each line of a field of an image, generating noise based on a current seed, inserting the generated noise in a current line of the field, and generating a new seed for processing a subsequent line of the field by shifting the current seed. The current seed may be used to generate a random number and the generated noise may be produced using this generated random number.
Claims30
A method for processing video data, the method comprising:
- for each line of a field in an image:
- generating noise based on a current seed;
- inserting said generated noise in a current line of said field;
- and
- generating a new seed for processing a subsequent line of said field by shifting said current seed.

A system for processing video data, the system comprising:
- at least one processor that:
- for each line of a field in an image:
- generates noise based on a current seed;
- inserts said generated noise in a current line of said field;
- and
- generates a new seed for processing a subsequent line of said field by shifting said current seed.
