METHOD AND APPARATUS FOR SMOOTH STREAM SWITCHING IN MPEG/3GPP-DASH |
摘要 |
A method and apparatus for providing smooth stream switching in video and/or audio encoding and decoding may be provided. Smooth stream switching may include the generation and/or display of one or more transition frames that may be utilized between streams of media content encoded at different rates. The transition frames may be generated via crossfading and overlapping, crossfading and transcoding, post-processing techniques using filtering, post-processing techniques using re-quantization, etc. Smooth stream switching may include receiving a first data stream of media content characterized by a first signal-to-noise ratio (SNR) and a second data stream of the media content characterized by a second SNR. Transition frames may be generated using at least one of frames of the first data stream and frames of the second data stream. The transition frames may be characterized by one or more SNR values that are between the first SNR and the second SNR. |
