VIDEOCODIERUNG MIT HYBRIDER TEMPORELLER UND SNR- BEZOGENER FEINGRANULARER SKALIERBARKEIT |
摘要 |
<p>A method for streaming enhancement layer video frame data on a variable bandwidth network involves coding original uncoded video data with a non-scalable codec to generate I and P base layer frames; generating residual temporal B frames and SNR I and P frames from the original uncoded video data and the base layer frames; coding the temporal and SNR frames with a scalable codec; determining an available bandwidth of the variable bandwidth network; transmitting at least portions of the scalable coded temporal frames when the available bandwidth is a first bandwidth ranging between a minimum bit-rate allocated for transmitting only base layer frames and a predetermined bit-rate which is below a maximum bit-rate of the network; and additionally transmitting remaining portions of the scalable coded temporal frames and at least portions of the scalable coded SNR frames when the available bandwidth is a second bandwidth extending between the predetermined bit-rate and the maximum bit-rate of the network.</p> |
