The invention discloses an adaptive audio output method, an adaptive audio output device, an audio transmitting end and an adaptive audio output system. The adaptive audio output method comprises the steps of determining whether an audio receiving end supports decoding to the audio format of an audio by an audio transmitting end; if yes, outputting the audio to the audio receiving end, and otherwise decoding the audio and outputting decoded audio data to the audio output end. According to the adaptive audio output method, whether the audio receiving end supports decoding to the audio format of the audio to be displayed is determined through the audio transmitting end, and furthermore a decoded audio flow or source code after decoding is automatically output according to a determination result, thereby enabling a user to hear the high-quality audio without any operation setting, preventing a problem of complicated setting in switching output equipment by the user each time, and improving user experience.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device, audio sending end and system for adaptive audio output. Background technique [0002] With the improvement of living standards and the rapid development of multimedia technologies, using terminal devices to watch videos or play games has become more and more popular in people's lives. People pay more and more attention to the sensory quality of audio and video, especially the higher and higher requirements for sound quality and stereo effects. Based on this requirement, many high-quality audio coding formats have been developed, such as Dolby Digital (DD, DD+), digital cinema system format, and audio coding data in advanced audio coding format to meet people's requirements for audio effects. [0003] Since the general digital video / audio interface (High Definition Multimedia Interface, HDMI) sender (such as smart TV box, etc.) needs to connect to...
