Embodiment 1

[0025] This embodiment is a high-precision broadcast control system of a channel packaging control machine, and the connection relationship inside the system is as follows: figure 1 As shown: the system includes a channel packaging control machine and a channel packaging rendering server; the channel packaging control machine includes an instruction compilation module, an instruction processing module and a serial communication interface; the instruction compilation module is connected to the instruction processing module, The instruction processing module is connected with the serial communication interface; the channel packaging control machine is connected with the channel packaging rendering server through the serial control interface and the corresponding communication cable; the instruction compilation module is provided with multiple compilation Object processing unit. in:

[0026] The channel packaging rendering server is responsible for receiving the scenes and templ...

Embodiment 2

[0032] This embodiment is a high-precision broadcast control method of a channel packaging control machine. The hardware system used in the method described in this embodiment includes: a broadcast control machine, the play control machine is connected to the rendering server through a serial port control link, and an instruction compiling module and an instruction processing module are arranged in the broadcast control machine. There can be multiple compilation objects in the command compilation module, and the connection relationship inside the system is as follows: figure 1 shown. The procedure of this method is as follows figure 2 shown.

[0033] The broadcast control machine described in this embodiment is a channel package broadcast control machine, which may be a standard server with various broadcast software and video boards. The rendering server is a workstation with rendering software or a server with strong computing capability. The serial port can be a serial...

Embodiment 3

[0056] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment regarding the control relationship between the channel packaging controller and the rendering server.

[0057] Theoretically, in the broadcast control system, one channel packaging control machine can control one rendering server to complete the packaging and broadcasting requirements of one channel. At this time, a single serial port point-to-point control can be used. However, in the actual application of the broadcast control system, in order to meet the high-definition and standard-definition simultaneous broadcasting requirements of channels, and to increase the reliability of channel packaging and broadcasting, one channel packaging controller is usually used to correspond to one channel, and control multiple rendering and broadcasting servers at the same time . These rendering and broadcasting servers correspond to different formats and functions of the channel,...

Abstract

The invention relates a control system and a control method of high-accuracy broadcasting of a channel packaging control machine. A hardware system used in the control method comprises a broadcasting control machine which is connected with a render server through a serial port control link, and an instruction compiling module and an instruction processing module are arranged in the broadcasting control machine. The control method includes the step of instruction differentiating, the step of instruction pre-sending, the step of sequencing and the step of instruction transmitting. Due to the measures of instruction importance differentiating, priority of important instruction, instruction pre-sending and avoiding, the serial port link which can not rapidly transmit high-accuracy instructions originally can meet the requirements of the instructions for a render controller by the transmission broadcasting control machine, and high-accuracy instruction transmitting is achieved through the existing serial port. The control method of the high-accuracy broadcasting of the channel packaging control machine can enable the channel packaging control machine to control the render server to broadcast accurately.

Description

technical field [0001] The invention relates to a high-precision broadcast control system and method of a channel packaging control machine, and is a system and method for realizing high-precision broadcast control by a digital broadcasting system of a TV station. It is a system and method for ensuring the broadcasting time accuracy and broadcasting safety of TV programs. Background technique [0002] The channel packaging and broadcasting system is a computer application system that combines templates, text, real-time information and other content on the broadcasting line in real time during the program relaying process in the broadcasting computer room, rendering and broadcasting. In the work flow of overall TV packaging and broadcasting, channel packaging is an important part of the overall application design and implementation, and is a part of broadcasting. It serves the same purpose as the overall packaging: it is to establish and maintain the brand image of the TV cha...
