Abstract

The invention provides a signal real-time monitoring method for a coder. The method can process the input/output signal of the coder and then perform real-time monitoring. Specifically, the method comprises: the video output signal of a capture card is processed by minification in image size and reduction in image frame rate, and the processed video/audio signals are transmitted to a display; or the coded signal is decoded and then processed by minification in image size and reduction in image frame rate; and finally the processed video/audio signals are transmitted to the display. The monitoring signal is displayed on a small window of the display, so that the operator can judge whether the output signal of the coder is correct or wrong by the observation through the small window. The invention can reduce the complexity of system application and the cost as well, and is convenient to operate.

Description

technical field [0001] The invention relates to the field of digital audio and video, in particular to a method for real-time monitoring of signals of an encoding device. Background technique [0002] The encoding device is a device that encodes and compresses the initial data and source of digital audio and video, that is, various input signals input by the acquisition card, such as: composite video signal (composite), serial digital interface (SDI) and S terminal input (S-Video) and other encoded signals into code streams that conform to source standards such as Mpeg2, H.264 / MPEG-4 AVC or AVS. When the encoder is working, in order to ensure the correctness and validity of the receiving terminal signal, it is often necessary to monitor whether the encoder is working normally at the signal transmitting end and whether the encoder has a predetermined output signal. At present, the usual practice is to connect the output signal of the encoder to a terminal device capable of d...
