Patent Images

1. A computer-implemented method of video coding with post-processing indication comprising:

  • obtaining image data of at least one image;

    encoding the image data in conformance with a video coding profile having a profile_tier_level syntax comprising profile syntax elements indicating conformance parameters of a video coding standard and for decoded video;

    using one of the profile syntax elements of the profile_tier_level syntax that is a general context interpretation code associated with alternative values and to indicate that the image is to be post-processed after decoding to modify the image data of the image to affect a display of the image, wherein a value of the general context interpretation code is one of three available alternatives of;

    a first value to indicate decoding without required post-processing,a second value to indicate post-processing is necessary after decoding, andany other value to indicate decoding may be skipped for the image data, andwherein the general context interpretation code is an existing profile syntax element originally established for reasons other than post-processing and used without modifying the video coding standard by adding codes for the post-processing; and

    providing the image data and profile_tier_level syntax settings in a bitstream to be transmitted to a decoder to have the image data decoded, post-processed after decoding depending on a setting of the general context interpretation code, and available to display images.
