Embodiment 1

[0029] In this embodiment, the display area of ​​the broadcast screen is as figure 2 As shown, it is required to broadcast the K-line chart of each stock in the Shanghai stock market in area 1, and the K-line chart of each stock in Shenzhen stock market in area 2, and the content in area 1 and area 2 is simultaneously scrolled .

[0030] To achieve the above requirements, the following three tasks are required:

[0031] Task (Shanghai stock market): Responsible for the broadcast of all Shanghai stock K-line charts, set to not automatically turn the screen;

[0032] Task (Shenzhen): Responsible for the broadcasting of all Shenzhen stock K-line charts, set to not automatically scroll;

[0033] Script plug-in: responsible for controlling when the first two tasks start broadcasting, when they stop broadcasting, and when they turn the screen.

[0034] For tasks (Shanghai Stock Market) and tasks (Shenzhen Stock Market): When the command is received, the K-line chart of the firs...

Embodiment 2

[0039] In this example, in figure 2 The stock prices of the Shanghai stock market and the Shenzhen stock market are broadcast in the display area 5 shown. It is required to turn the screen to broadcast the prices of all Shanghai stock stocks, then broadcast all the stock prices of the Shenzhen stock market, and then broadcast the Shanghai stock market, so Repeatedly.

[0040] To achieve the above requirements, the following three tasks are required:

[0041] For tasks (Shanghai Stock Market) and tasks (Shenzhen Stock Market), it is set to automatically flip the screen at 2000 milliseconds, and after playing all the data once, it will automatically stop and send a command to the script plug-in. The instruction queue in the script plugin is as follows Figure 4 shown.

[0042] When the script plug-in receives the "start command", set m_nCurIndex to 1, and return after waiting for 1 millisecond.

[0043] After waiting for 1 millisecond, read the m_nCurIndex inst...

Abstract

The invention relates to a method for controlling the execution of a broadcast task by using a script plug-in, and belongs to the technical field of information automatic broadcasting. The present invention uses a script plug-in to control the execution of the broadcast task, and the script plug-in includes an instruction queue for controlling the execution mode of the broadcast task, and the instruction types include label-type instructions, delay-type instructions, operation-task-type instructions and jump-type instructions ; Start running when the playbook plugin receives the start command. Take instructions from the instruction queue, perform corresponding operations according to different instruction types, and execute the last instruction. The invention greatly reduces the workload and the number of tasks for creating and broadcasting tasks, and is beneficial to the maintenance of tasks. At the same time, it is very convenient to realize the cooperative work requirements among multiple tasks, such as precisely controlling the synchronous operation of two tasks.

Description

technical field [0001] The invention belongs to the technical field of automatic broadcasting of information, and specifically relates to a method for controlling the execution of broadcasting tasks by using a script plug-in, which is suitable for occasions requiring automatic broadcasting of information, such as television stations, airports, and stock exchanges. Background technique [0002] In the field of information automatic broadcast technology, the demand for graphic information broadcast is very large, and the demand is varied. At present, for each individual requirement, it is necessary to program and write program codes to achieve specific functions, that is, the method of controlling tasks is fixed by writing program codes, which requires a lot of work, and the programs are not easy to modify and maintain. Moreover, in specific work, some needs still cannot be met. For example, precise control over the simultaneous operation of two tasks. Contents of the inven...
