Vehicle information entertainment product lossless audio frequency play method, vehicle information entertainment product, mobile terminal and vehicle

Abstract

The embodiment of the invention provides a vehicle information entertainment product lossless audio frequency play method, a vehicle information entertainment product, a mobile terminal and a vehicle,belonging to the technical fields of vehicle information entertainment products. The vehicle information entertainment product lossless audio frequency play method is used for vehicle information entertainment products. The method comprises the steps of: establishing data connection with a mobile terminal through a communication interface; receiving lossless audio frequency data from the mobile terminal through the communication interface; and playing the received lossless audio frequency data. According to the technical scheme, when the vehicle information entertainment product communicateswith the mobile terminal through the communication interface, and communication of lossless audio frequency data is performed through the communication interface to achieve high-quality audio frequency output of the vehicle information entertainment product terminal.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular, to a method for playing lossless audio in vehicles, vehicles, mobile terminals and vehicles. Background technique [0002] At present, with the rapid development of car-machine technology and smart phone technology, there are more and more interconnection solutions between car-machine and smart phone. Generally, compared with smart phones, car phones have a larger display screen, which is convenient for drivers to watch, while smart phones have more functions than car phones. Therefore, interconnecting the car machine and the smartphone through a communication interface can bring a better user experience. [0003] Audio data is generally provided in the form of audio files. Common audio file formats such as MP3 and WMA are lossy compression formats. Compared with WAV files as the source, they all have a considerable degree of signal loss, which is why they can achieve a ...

Problems solved by technology

When the car machine, such as a navigator, is in the process of realizing the interconnection between the car machine and the smart phone, due to the bandwidth limitation of the Bluetooth and USB interface, the car machine cannot obtain high-quality lossless audio content with a high bit rate from the smart phone. The interconnection between car and smartphone brings limitations
