Abstract: This application relates to video encoding and decoding, and specifically to tools and techniques for using and providing supplemental enhancement information in bitstreams. Among other things, the detailed description presents innovations for bitstreams having supplemental enhancement information (SEI). In particular embodiments, the SEI message includes picture source data (e.g., data indicating whether the associated picture is a progressive scan picture or an interlaced scan picture and/or data indicating whether the associated picture is a duplicate picture). The SEI message can also express a confidence level of the encoder's relative confidence in the accuracy of this picture source data. A decoder can use the confidence level indication to determine whether the decoder should separately identify the picture as progressive or interlaced and/or a duplicate picture or honor the picture source scanning information in the SEI as it is.

Abstract: A method of converting 10-bit pixel data (e.g. 10:10:10:2 data) into 8-bit pixel data involves converting the 10-bit values to 8-bits using a technique that is selected dependent upon the values of the MSBs of the 10-bit values and setting the value of an HDR flag dependent upon the values of the MSBs. The HDR flag is appended to the 3-bit channel.

Abstract: Disclosed are systems and methods for the out-of-order predictive streaming of elements from a three-dimensional (“3D”) image file so that a recipient device is able to produce a first visualization of at least a first streamed element from a particular perspective, similar to the instant transfer of two-dimensional (“2D”) images, while the additional elements and perspectives of the 3D image are streamed. The sending device prioritizes the 3D image elements based on a predicted viewing order, streams a particular element from a particular perspective with a priority that is greater than a priority associated with other elements and other perspectives, determines a next element to stream after the particular element based on the next element being positioned adjacent to the particular element and having a priority that is greater than adjacent elements, and streams the next element to the recipient device.
