Abstract
Methods, apparatus, systems, and articles of manufacture are disclosed that distribute video data encoded with scalable video coding. A remote data source analyzes the graphics system of one or more client device(s), generates a full video frame data and a base-layer video frame, encodes an auxiliary-layer bitstream, and transmits the bitstream to the client device(s). The remote data source does not need to encode or transmit a base-layer bitstream. The client device(s) generates a base-layer frame data, decodes the auxiliary-layer bitstream into an auxiliary-layer frame data, and reconstructs a full video frame based on the second base-layer frame data and the auxiliary-layer frame data. The methods, apparatus, systems, and articles of manufacture disclosed herein save bandwidth by transmitting only the auxiliary-layer bitstream to one or more of the client device(s) without a base-layer bitstream. The client device(s) graphics system is utilized to generate its own base-layer frame data.
