Abstract
A method and video decoder system using the method are provided for identifying video frames in an encoded or encrypted video stream without performing decoding or decryption. The method includes: receiving a video data stream comprised of a plurality of transport stream (TS) packets; detecting a first video frame in the video data stream, wherein detection of the first video frame includes registering a last checked position at the start of the video data stream, examining bytes in a next TS packet to identify a predetermined pattern indicating a network abstraction layer (NAL) unit, repeating the examining step until two TS packets have been identified that include an NAL unit, wherein the last checked position is updated after each examining step, and identifying a video frame based on a position of the NAL unit identified in the two TS packets; and repeating the detecting step for a plurality of additional video frames in the video data stream.
