Abstract: A supporting rack for supporting a thin screen at least comprising a base, a supporting rod set and a screen positioning set, the supporting rod set is provided at a position higher than the top of the screen positioning set with a connecting member, a supporting arm and two supporting seats to support and fix a plate for placing articles, the plate for placing articles thus can form a platform, thereby the supporting rack can be used for placing peripheral devices or other articles for documentary works in addition to supporting the screen; and the space above the screen can be effectively used.

Abstract: A method for transporting data is provided. The method can manage the buffer and communicate between a sender and a receiver by protocol to improve the performance of data transportation and real-time data playing. Moreover, the size of the buffer in the sender equals to that of the pre-buffer in the receiver, and the total amount of data held therefore is constant, thereby fixes the delay period to keep the real-time data played at a steady speed.

Abstract: A method for representing the items of a data, especially an audio data, by using fixed bits, is provided. The method can improve the speed to compress and decompress the data and reduce the load of the processor.

Abstract: A method for transporting real-time audio and video data is provided, wherein a partial encryption method merely encrypts some packets or some segments thereof in the data stream thereby improve the speed of data process and reduce the load of the processor. Especially for audio data, the malicious interceptor cannot hear the audio data clearly although it is merely partially encrypted.
