Abstract: A server device, a client device and a dynamic image transmission method for a virtual desktop infrastructure are provided. The dynamic image transmission method for the virtual desktop infrastructure includes the following steps. A region information of a dynamic image displayed on a server device is detected by the server device. The region information is transmitted to a client device by the server device. The dynamic image is rendered on the client device according to the region information. The dynamic image is obtained from an Internet by the client device according to a network link information obtained from the server device, or the dynamic image is obtained by decompressing a compressed data provided from the server device.

Abstract: A method for frame memory compression divides each of a plurality of image frames in a frame memory into a plurality of blocks and quantizes a plurality of pixel values inside each block according to a predefined parameter, thereby generating a quantized block and a plurality of removed bits from the binary representation of the plurality of pixel values. A predictor is used to produce a residual block for the quantized block. A variable length encoder takes the residual block as an input and produces a coded bitstream. A packing unit is used to take the coded bitstream and the number of removed bits generated by the quantizer as inputs, so as to produce an entire codeword sequence of the block that meets a target bit rate by using a structure called group of blocks (GOB) to flexibly share available spaces of the blocks in the same GOB.
