METHOD AND DEVICE FOR SEAMLESS-DECODING VIDEO STREAM INCLUDING STREAMS HAVING DIFFERENT FRAME RATES

摘要

A decoding apparatus (VDA) for decoding a mixed video stream (STv) of a plurality of streams (interlace scheme, progressive scheme) of different frame rates in predetermined decode timing (Vmc) for seamless playback, the apparatus including a stream analyzer (Ddv, 2) for extracting each frame rate before the plurality of streams (IS, PS) are decoded and a video decode controller (CDV) for determining the timing (Vmc) for decoding a slice layer (SL) of the video stream (STv) based on the extracted frame rate. The video stream (STv) is decoded in the determined timing (Vmc). Even if the video stream (STv) is switched between the streams (IS, PS) of different frame rate, seamless playback can be carried out. <IMAGE>
