Description of the invention (, /), the invention relates to a computerized multi-channel digital sound signal transmission method and device thereof, especially-a method applied to multiple The sound card of the sound channel allows the sound card to be connected with multiple taste bars through a single-transmission medium, so as to achieve a structured stereo surround sound field. With the rapid development of the electronics and semiconductor industries, early computers only had text day and day functions, and gradually evolved to have multimedia audio and video playback functions. The support for audio and video playback functions was nothing more than adding a video interface card or sound card. At present, there are also Launched a product that integrates sound card circuits on the motherboard to reduce the size of the host. In addition, with the technological breakthroughs in the related audio and video industry, whether it is the device used to store sound and video or the compression processing of sound and video, it is said to be advanced and innovative. For example, recent VCDs and DVDs have exhibited quite iconic symbols. Products, and DVDs with high day quality and high sound quality, which are matched with the computer's DVD PLAYER and screen can only play pictures with better picture quality, and the sound effect part, the general computer often uses only the right and left channel sound effects Card, with two hundreds of watts of La alpha eight to form a broadcasting device, however, because only two-channel 70 can not play stereo surround sound, even with PLAYER still can not get high-quality enjoyment, so the sound effects are quite required Users will replace the multi-channel sound card together with at least five sets of speakers to build a set of theater sound sets with surround sound effects. Due to the size of the computer desk, general electric users, if multiple groups of ports are set up, and in addition to the power supply line, please refer to the sixth figure, you still need to use an additional sound power cable (70).
