Method and apparatus for generating encoded content using dynamically optimized conversion

摘要

An initial content is encoded a first time to obtain a first encoded content. One or more parameters obtained from the first encoding are used to generate an encoding coefficient. The initial content is encoded a second time to obtain a second encoded content. The second encoding is performed using encoding coefficients, at least one of which is derived from the parameter associated with the first encoding. The two encodings can be implemented using a single encoder or two separate encoders.

1. An apparatus for generating encoded content in an output format from an initial content in an initial format, said initial content having been used by an earlier encoder to generate a first encoded content using at least one first encoding coefficient, said first encoded content having a first format compatible with a first content player, said apparatus comprising:
an analyzer receiving said first encoded content and being configured to generate a first parameter based on said first encoded content; a current encoder receiving said initial content and a second encoding coefficient and encoding said initial content into a second encoded content in accordance with at least said second encoding coefficient, said second encoded content having a second format, said second format being different than said first format; and a coefficient generator including a mapping member, said coefficient generator receiving said first encoding coefficient from a parameter log derived from said initial encoder, said coefficient generator receiving said first parameter and generating said second encoding coefficient by mapping said first parameter with said mapping member.
