Abstract
A method of processing media data. The method includes determining, for a conversion between the media data and a media data file, whether a preselection element includes an indicator, wherein the indicator indicates that video data units representing a target picture-in-picture region of a main video are able to be replaced by corresponding video data units of a supplementary video; and performing the conversion between the media data and the media data file based on the indicator. A corresponding video coding apparatus and non-transitory computer-readable recording medium are also disclosed.
Claims20
A method of processing media data, comprising:
- determining, for a conversion between the media data comprising a main video and a supplementary video and a media data file under Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH), whether a DASH preselection element includes an indicator, wherein the indicator included in the DASH preselection element indicates that whether video data units representing a target picture-in-picture region of the main video of the media data are able to be replaced by corresponding video data units of the supplementary video of the media data, and wherein the indicator included in the DASH preselection element comprises an attribute of the DASH preselection element;
- and
- performing the conversion between the media data and the media data file based on the determining.
An apparatus for processing media data comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
- determine, for a conversion between a media data comprising a main video and a supplementary video and a media data file under Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH), whether a DASH preselection element includes an indicator, wherein the indicator included in the DASH preselection element indicates that whether video data units representing a target picture-in-picture region of the main video of the media data are able to be replaced by corresponding video data units of the supplementary video of the media data, and wherein the indicator included in the DASH preselection element comprises an attribute of the DASH preselection element;
- and
- performing the conversion between the media data and the media data file based on the determining.
A method for storing a media data file under Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH), comprising:
- determining, for a media data comprising a main video and a supplementary video, whether a DASH preselection element includes an indicator, wherein the indicator included in the DASH preselection element indicates that whether video data units representing a target picture-in-picture region of the main video of the media data are able to be replaced by corresponding video data units of the supplementary video of the media data, and wherein the indicator included in the DASH preselection element comprises an attribute of the DASH preselection element;
- generating the media data file based on the determining, and storing the media data file in a non-transitory computer-readable recording medium.
