Abstract
A virtual desktop can be remoted to a client device by transmitting a video stream using a video coding format, such as H.264, where higher resolution video can be streamed than natively supported by the encoder or decoder. The encoder framebuffer is divided into a plurality of equal size child buffers, each child buffer is assigned an identifier for identifying the child buffer. Padding pixels can be added to the child buffers to make the child buffer size acceptable for the video coding format. The child buffers are encoded using the video coding format and the encoded frames are transmitted to a client. On the decoder side, the encoded child frames are decoded, padding pixels are removed, and the data is used to update corresponding child buffers in a framebuffer on the client display system.
