Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and several embodiments. It should be noted that, in the case of no conflict, the features in the embodiments of the present application can be combined arbitrarily with each other.

[0036] In the channel broadcast system, according to the existing broadcast execution order, control the signal source equipment and switching equipment, and output the designated program signal at the designated time. If you want to ensure the accuracy of broadcast control, you must not only achieve independent control accuracy for the signal source device and switching device, but also need to coordinate the timing relationship between the two to achieve "zero frame" control accuracy.

[0037] In this embodiment, the signal source equipment includes: a video server and a media video rec...

Abstract

The invention discloses a multi-equipment cooperative control method and equipment and belongs to the technical field of television broadcasting. The method comprises the steps of when a field interrupt signal of a channel broadcast system is received, triggering a synchronizing signal of a plurality of pieces of cooperative work equipment in the channel broadcast system; simultaneously starting a plurality of concurrent threads according to the synchronizing signal, inquiring whether an instruction to be executed exists in an instruction execution queue of the cooperative work equipment, if so, confirming whether the instruction to be executed reaches execution time, if the instruction to be executed reaches the execution time, triggering the threads of the cooperative work equipment to send the instruction to be executed. A mode that a plurality of equipment control threads independently control the equipment is adopted, the concurrent real-time control of multiple pieces of equipment is supported, the synchronizing signal is introduced, the synchronous trigger effect of an independent thread control mode is realized, all instructions are enabled to be sent after the field interrupt signal reaches, and the precision control on a plurality of cooperative work equipment is realized.

Description

technical field [0001] The invention relates to the technical field of television broadcasting, in particular to a multi-device cooperative control method and device. Background technique [0002] In the channel broadcasting system, it is often necessary to control the cooperative work of multiple devices at the same time, such as controlling the system work of the signal source device and the switcher device. These devices may have different timing requirements. If the commands received by these devices are coordinated Time misalignment, even a very small error, may lead to a decrease in broadcast accuracy. [0003] The current automatic broadcast control system generally adopts VDCP (Video Disk Communications Protocol, video disk communication protocol), controls the video server through the serial port (422), and controls the server to play by sending a suitable command sequence to the server at a specified time point. At the same time, in the process of control, it is n...
