Stereo lossless transmission system

Abstract

The invention relates to a stereo lossless transmission system. The transmission system at least comprises a mobile terminal, a signal receiver, a data processor, a first sound box and a second soundbox. According to the system, the data processor finishes carrying out sound channel identification on audio data and carrying out location allocation on the audio data of corresponding sound channelsaccording to sound channel information, so the defect that for each sound box in the existing wireless transmission sound box system, a sound channel data identification device needs to be set to carry out sound channel identification and location matching on the data sent to the sound channel data identification device is avoided, and the device cost is reduced. In a process that the data processor sends second data to the first sound box and / or the second sound box, extraction and compression of the audio data of different sound channels are not carried out on the data, so the possibility of reducing the sound quality due to data damage is avoided.

Description

technical field [0001] The invention relates to the field of signal transmission, in particular to a stereo lossless transmission system. Background technique [0002] The birth of the phonograph in the 1870s ushered in the first monophonic sound system. However, in that era, the phonograph was a luxury that only the nobles could enjoy, and it could not be popularized by the public. Later, tube radios and transistor radios gradually entered people's daily life, but what people can hear is still the same monophonic sound system. Since the 1920s, stereo systems have been used in commercial operations in developed countries such as the United States, Britain, and France. Stereo technology began to be adopted on a large scale in 1957 when the Radio Corporation of America (RCA) first introduced stereo recordings into commercial applications. In 1977, Dolby Laboratories successfully developed a multi-channel surround system—Dolby Stereo (Dolby Stereo), so far, audio officially ...

Problems solved by technology

The wiring of general home theaters is complicated and unsightly, but with the emergence of wireless home theaters, life has changed since then. The wireless local area network transmission method can not only beautify the living room, but also enjoy high-quality audio-visual. In the data process, each speaker receives the audio data extracted for the channel, but in the process of extracting the data corresponding to each channel in the audio data, data corruption is prone to occur, thereby reducing the audio quality; or wireless Each speaker in the transmitted speaker system needs to be equipped with a channel data identification device to complete the channel identification and position matching of the data sent to it, thus increasing the equipment cost and greatly increasing the data processing capacity of each device, reducing the data processing efficiency
