Video decoding method/device of detecting a missing video frame

摘要

Video decoding device is disclosed. The video decoding device comprises a demultiplexer, a first decoder and a controller. The demultiplexer receives a Transport Stream to recover video Packetized Elementary Stream (PES) to determine a presentation time stamp (PTS) and a decoding time stamp (DTS) in a PES header of the PES. The first decoder retrieves a video frame from the video PES to determine temporal reference of the video frame. The controller receives the PTS, the DTS, and the temporal reference to determine whether there is a missing video frame.

1. A video decoding method, comprising:
recovering video Packetized Elementary Stream (PES) to determine a presentation time stamp (PTS) and a decoding time stamp (DTS) in a PES header of the PES; retrieving a video frame from the video PES to determine temporal reference of the video frame; and determining that there is no missing video frame when the temporal reference of a current video frame is consecutive to the temporal reference of a previous video frame in display order, the DTS of the current video frame does not exceed the DTS of the previous video frame by a predefined time interval, and the PTS of the current video frame does not exceed the PTS of the previous video frame by the predefined time interval.
