Abstract

The invention discloses a Bluetooth sound controlling video-on-demand system which comprises a sending module and a receiving module. The sending module comprises a voice collecting part, a pre-treating part which is connected with the voice collecting part and a Bluetooth modulating and sending part which is connected with the pre-treating part; the receiving module comprises a Bluetooth receiving part, a modulating and converting part, a digital signal processor and an external interface part which is connected with the digital signal processor. The Bluetooth sound controlling video-on-demand system of the invention is no longer controlled manually when choosing video or audio programs, thus greatly reducing the trouble of key-pressing operation, is convenient, quick and reliable, provides the easier and more convenient selection of the programs, with high stability and low power consumption and is applicable to video on demand of KTV, Kara OK televisions and films, etc.

Description

【Technical field】 [0001] This creation relates to the technical field of on-demand control of audio and video programs, in particular to a bluetooth voice-controlled on-demand system. 【Background technique】 [0002] At present, as people spend more and more time for leisure and entertainment activities, their requirements are also getting higher and higher, especially when performing audio-visual entertainment programs, it is required to be able to broadcast programs conveniently, quickly and accurately and switch. However, the video-on-demand systems currently on the market are all operated manually through remote controllers or directly on the keyboard, which is cumbersome and inconvenient for consumers, and consumers cannot perform other activities simultaneously during the operation control process. In order to improve the reliability, convenience and ease of use of the on-demand system, it is necessary to develop a Bluetooth voice-activated on-demand system, which can b...
