Problems solved by technology

At present, in the process of receiving audio data from the speakers, 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 and the audio quality will be reduced. or each speaker in the wireless transmission 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 cost of equipment and greatly increasing the cost of each device. The amount of data processing reduces the efficiency of data processing

Embodiment

[0015] A multi-channel lossless transmission system, such as figure 1 shown. The multi-channel lossless transmission system includes an audio data collection end, an audio data processing end and at least two sound boxes. Preferably, the sound boxes include the first sound box, the second sound box and up to the nth sound box.

[0016] The audio data collection terminal is used to realize audio data collection. The audio data processing terminal is used to implement channel division and playback position allocation for the collected audio data.

[0017] Preferably, the audio data collection terminal includes, but is not limited to, smart phones, tablet computers and notebook computers. The audio data collection terminal completes the collection of audio data through wired and / or wireless means, that is, the collection and acquisition of audio data can be realized through wired cables, 4G, Bluetooth, WiFi, and the like.

[0018] Preferably, the audio data processing end div...

Abstract

The invention relates to a multi-channel lossless transmission system. The multi-channel lossless transmission system comprises an audio data collection end, an audio data processing end and at leasttwo sound boxes. In the system provided by the invention, in the process when the audio data processing end sends playing audio data to a first sound box, a second sound box to the nth sound box, thedata are not extracted or compressed for the audio data of different channels, thereby avoiding the possibility of reducing the sound quality due to data corruption.

Description

technical field [0001] The invention relates to the field of audio data transmission, in particular to a multi-channel 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 the multi-channel surround system - Dolby Stereo (Dolby Stereo), so far the...
