Abstract

Supplemental processing information defining post-decoding instructions for processing decoded media content is co-organized in a file together with a pseudo-identifier of a media codec employed for encoding the media content. The co-organization trigger abortion of decoding of the media content by a legacy media terminal that does not recognize the pseudo-identifier but enables decoding of the media content by a media terminal that recognizes the pseudo-identifier to thereby enable post-decoding processing of the decoded media content using the supplemental processing information. The co-organization thereby prevents legacy media terminals that cannot use the supplemental processing information from decoding the media content and rendering the media content in a media presentation.
