Abstract
Official abstract text for this publication.
In one example, a video coder is configured to code a value for a syntax element indicating whether at least a portion of a picture order count (POC) value of a picture is to be reset to a value of zero, when the value for the syntax element indicates that the portion of the POC value is to be reset to the value of zero, reset at least the portion of the POC value such that the portion of the POC value is equal to zero, and code video data using the reset POC value. Coding video data using the reset POC value may include inter-predicting a block of a subsequent picture relative to the picture, where the block may include a motion parameter that identifies the picture using the reset POC value. The block may be coded using temporal inter-prediction or inter-layer prediction.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of decoding video data, the method comprising: determining whether a value for a syntax element indicates that at least a portion of a first picture order count (POC) value of a first picture is to be reset to a value of zero; when the value for the syntax element indicates that the portion of the first POC value is to be reset to the value of zero; resetting at least the portion of the first POC value such that the portion of the reset first POC…
