Abstract

The invention relates to a safe broadcast monitoring method based on video and audio comparison, which comprises the following steps: (a) receiving two paths of signals, wherein the two paths of signals are broadcasted by the same broadcast signal source; (b) aligning the two paths of signals according to a time stamp mechanism; (c) accumulating video and audio data of the two paths of signals; (d) extracting the video and audio data, and comparing the signals; and (e) processing the comparison results. By introducing the method of comparing two paths of signals, the automatic objective analysis of the technical index of the last-stage broadcast signal is realized in a broadcast channel sub-control system. When the signal difference exceeds the limited threshold range, a warning message is automatically released to the related workstation in the system to prompt the related personnel to carry out the necessary processing operation, thereby finishing the quick processing of faults. The invention is not limited by the subjective judgment capability of the personnel, greatly relieves the workload and the mental pressure of the broadcast personnel in a television station, effectively avoids the occurrence of broadcast accidents, and greatly improves the broadcast safety.

Description

technical field

[0001] The invention relates to a safe broadcast monitoring method based on video and audio comparison, which is a method for analyzing, comparing and alarming the final signal by the broadcast channel sub-control system under the computer network environment. It is a method of analyzing, comparing and alarming the transmitted signals, which is a safe broadcasting monitoring technology for the broadcasting system of the TV station. Background technique

[0002] Usually, when TV stations design and build broadcast control systems, broadcast security is the primary consideration, and safe broadcast is the ultimate goal of every TV station's broadcast system. For the broadcast sub-control system, the security of the broadcast system can be realized in various ways, such as adopting a redundant backup structure for the core equipment inside the system to avoid a single failure point; optimizing the broadcast by improving the application program The control logic...
