METHOD AND APPARATUS FOR SMOOTH STREAM SWITCHING IN MPEG/3GPP-DASH

摘要

a method and apparatus for providing a seamless stream switching at the time of the video and / or audio encoding and decoding may be provided. Seamless switching stream may include at least one transition of the generated frames and / or a display which may be used in between the streams of the media content encoded at different rates. After the transition frame is to use a cross-fading and overlap, cross-fading and transcoding, filtering techniques, and the like may be generated through the post-processing techniques that use a re-quantization. Seamless stream switching may include the step of receiving the second data stream of media content, characterized by a first data stream and the second SNR of media content that is characterized by the first signal-to-noise ratio (SNR). Transition frames may be generated using at least one of the frames of the first data stream and a second data stream of the frame. Transition frames may be characterized by one or more SNR value between the first SNR 1 and SNR claim 2.
