Abstract
Official abstract text for this publication.
A video coding apparatus may be configured to utilize media extractors in a media extractor track that reference two or more non-consecutive network access layer (NAL) units of a separate track. An example apparatus includes a multiplexer to construct a first track including a video sample comprising NAL units, based on encoded video data, wherein the video sample is included in an access unit, construct a second track including an extractor that identifies at least first one of the NAL units in the video sample of the first track, and wherein the extractor identifies a second NAL unit of the access unit, wherein the first identified NAL unit and the second identified NAL unit are non-consecutive, and include the first track and the second track in a video file conforming at least in part to ISO base media file format. The identified NAL units may be in separate tracks.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for encoding video data, the method comprising: constructing, by a source video device, a first track including a video sample comprising a plurality of network access layer (NAL) units based on encoded video data, wherein the video sample is included in an access unit; constructing, by the source video device, a second track including a plurality of extractors, the plurality of extractors including an extractor that identifies a plurality o…
