Problems solved by technology

For example, someone may have a movie that cannot be fully displayed, and the media terminal will only find that it cannot display the movie correctly when unknown SEI messages are involved

Embodiment 1

[0030] Embodiments relate generally to media content processing, and in particular, to the provision and use of supplemental processing information that can be used by media terminals and players to process and / or render decoded media content.

[0031] Embodiments provide efficient ways of delivering such supplemental processing information to media terminals. Communication of the supplemental processing information allows media terminals aware of the supplemental processing information to retrieve it and use it for processing the media content prior to or during rendering. However, the supplemental processing information is advantageously communicated in such a manner that legacy media terminals that do not recognize the supplemental processing information will not render the media content. This is preferred because such media content rendering will result in visual and / or audio artifacts perceived by the user, while legacy media terminals will not perform post-decoding proce...

Abstract

Supplemental processing information (52, 54) defining post-decoding instructions for processing decoded media content is co-organized in a file (1) 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 (210) that does not recognize the pseudo-identifier but enables decoding of the media content by a media terminal (200) that recognizes the pseudo-identifier to thereby enable post-decoding processing of the decoded media content using the supplemental processing information (52, 54). The co-organization thereby prevents legacy media terminals (210) that cannot use the supplemental processing information from decoding the media content and rendering the media content in a media presentation.

Description

technical field [0001] Embodiments relate generally to media content processing, and in particular to providing supplemental processing information useful in conjunction with media content processing. Background technique [0002] H.264 / MPEG-4 Part 10 or Advanced Video Coding (AVC) is the latest technological development video coding standard. It is a hybrid codec which takes advantage of eliminating redundancy between frames and within a frame. The output of the encoding process is Video Coding Layer (VCL) data, which is further encapsulated into Network Abstraction Layer (NAL) units before transmission or storage. [0003] Supplemental Enhancement Information (SEI) is provided to aid in post-decoding related processes such as display. Examples of SEI messages include defining filter cues and tone mapping. SEI messages are designed in such a way that they are not mandatory for the decoding process. Compliant decoders can discard SEI messages they do not understand. SEI...
