Claim Text:
1. A video transferring system comprising: a transmission apparatus that transmits a video stream as a scalable encoded data including a base layer and a first base quality extension layer in real-time; and a reception apparatus that receives the video stream via a network, wherein the transmission apparatus comprises: a transmitter that transmits, in response to receiving a rewind signal, a second base quality extension layer instead of the first base quality extension layer with the base layer within a limited bandwidth, wherein the reception apparatus comprises: a receiver that receives the video stream and divides the scalable encoded data into each layer; a memory that stores the real-time transmitted base layer and the first base quality extension layer; a layer synthesizer that synthesizes the real-time transmitted base layer and first base quality extension layer to create a base quality video signal at normal times, and synthesizes the pre-stored base layer and first base quality extension layer, and the real-time transmitted second base quality extension layer to create a high quality rewind video signal in response to the rewind signal; and a display that displays the created high quality rewind video signal at the same time as displaying the base layer.
