Method to play a video data stream, device and computer program

摘要

the present disclosure relates to a method to play a video data stream, to a device and to a computer program. The device (102) has an input circuit (114) to receive a stream of video data, which includes intra-frames (I-frames) and inter-frames. A video frame parser (124) separates the I-frames and inter-frames from the stream of video data. Memory (120) has a file system thereon, and a processor (116) is arranged to process the video data. The processor stores the I-frames in an I-frame file (178) and stores the inter-frames in an inter-frame file (180). The processor also stores an index file (182), which includes information to coordinate a pre-parsed position of each I-frame with at least one adjacent inter-frame.
