Abstract
Methods for transmitting and receiving multimedia video data and a device thereof are disclosed to improve multimedia video data playout quality. The transmitting method comprises: configuring different data channels for key frame data and non-key frame data, and configuring a larger bandwidth for the key frame data channel than that for the non-key frame data channel; when transmitting the data to a receiving end, bearing the key frame data and the non-key frame data on different data channels to transmit according to the configuration. The receiving method comprises: sending a resource request to a source end; establishing multiple data channels with the source end according to the configuration content fed back by the source end; receiving the key frame data and the non-key frame data on different data channels; merging and outputting the received key and non-key frame data.
