Data Transmission and Processing of DTTV USB Testing Receiver in China |
| |
| Abstract: | Analysis and processing of bit stream have great meaning in signal coverage testing during construction of DTTV network. With high speed and universality of the USB2.0 interface, data stream created by receiving terminal is transmitted to a computer to be analyzed and post-processed. And that is helpful to development of a DTTV testing system. This article introduces how to combine USB2.0 and DirectShow to develop data transmission and processing system of DTTV USB testing receiver. |
