Title: USB-BASED DATA TRANSMISSION METHOD AND SYSTEM THEREOF
Abstract:
The present invention relating to a USB-based data transmission method and a system thereof. The method comprises: defining transmission priorities of different data; sequentially transmitting video data in a defined order of high priority, medium priority, and low priority; counting the data which are being transmitted currently, and calculating the instantaneous bandwidth demands of various channels; and carrying out corresponding adjustments to the transmission loads and bandwidths of different channels. By means of predefining the transmission priorities of different data, different types of data transmission are performed according to the different transmission priorities; moreover, the loads and bandwidths of different channels are adjusted to achieve the transmission of real-time ultra-high-definition audio and video data, and also transmit multi-path high-definition audio and video data simultaneously. During the transmission of the audio and video data, communication control, state information exchange, file upload and download operations of both sides of the communication are achieved, thus facilitating a user expanding custom communication functions.
