Picture output management in video applications with fixed picture rate

摘要

In one embodiment, a video bitstream is received at a video processing device. The bitstream may be decoded by the video processing device to produce a first picture data and a second picture data. The decoded first picture data and decoded second picture data may be stored in a decoded picture buffer. The first decoded picture data has a corresponding first picture rate and the second decoded picture data has a corresponding second picture rate. Auxiliary information corresponding to the bitstream may be received for the first picture data and second picture data at the video processing device. The decoded first picture data stored in the decoded picture buffer may be processed by the video processing device based on the received auxiliary information. The decoded first picture data may be processed based on the auxiliary information to produce a version of the first picture data at the second picture rate, the second picture rate being different from the first picture rate.

1. A method for video processing comprising:
decoding by a video processing device a video stream to produce a first picture data; storing the decoded first picture data in a decoded picture buffer, the first decoded picture data corresponding to a first picture rate; receiving auxiliary information corresponding to the video stream, the auxiliary information comprising a first flag indicative of a rate change and a second flag indicative of a presence of a picture output index table that specifies a value corresponding to a number of repetitions of at least one picture stored in the decoded picture buffer; and processing the decoded first picture data stored in the decoded picture buffer based on the received auxiliary information, wherein processing the first picture data based on the auxiliary information comprises repeating the first picture data based on the value corresponding to the number of repetitions of the at least one picture to produce a second picture data having a second picture rate different from the first picture rate.
