    摘要： The network unit includes a signaling unit and a video transmitting unit. The signaling unit is configured to receive a request from a decoding device requesting transmission of the video channel. The video transmitting unit is configured to transmit the video channel towards the decoding device, initially as a dedicated multimedia stream dedicatedly supplied to the decoding device and including an anchor frame as a first transmitted video frame, and further in time as a common multimedia stream commonly supplied to a plurality of decoding devices. The video transmitting unit is further configured to transmit the video channel within the dedicated multimedia stream having an earlier time frame with respect to transmission of the video channel within the common multimedia stream, and the video channel is to be initially played at an averagely slower motion speed than the nominal motion speed that the common multimedia stream is to be played.
