Embodiment 1

[0030] In this embodiment, the video data output devices are the first video monitor and the second video monitor.

[0031] The output control device receives a control command input by the user through the application software interface on the display itself, and the control command specifies that the first video data to be played is simultaneously output to the first video monitor and the second video monitor. According to the above instructions input by the user, the output control identifier is determined to be a two-digit string "11", wherein the number of digits of the output control identifier expresses the number of video output devices, and each bit of the output control identifier describes the corresponding video output The output status of the device, for example, the first digit "1" in the output control identifier "11" indicates that the output status of the first video monitor is normal output; the second digit "1" in the output control identifier "11" indicates ...

Embodiment 2

[0043] In Embodiment 1, when the first video monitor outputs the second video data to be played, and the second video monitor finishes playing the black field data corresponding to the second video data to be played, the output control device needs to output a 2. The output size of the video data to be played is the same as the information of the number of data bits corresponding to each pixel. The 3rd video data to be played is received at this time by the user through the application software interface input on the display. Output the third video data to be played to the first video monitor and the second video monitor, and determine the output control identifier as "00" according to the above-mentioned control instruction input by the user;

[0044] The output control device copies the third video data to be output to the first buffer; at the same time, according to the output control identifier "00", it is determined that the first video monitor and the second video monitor...

Abstract

The embodiment of the invention provides a video data output system, a video data output method and an output control device, which are used for solving the problems of troublesome user operation and poor feeling during browsing TV program contents in the prior art. The system comprises the output control device and at least one video output device, wherein the output control device is used for receiving a control command which is input by a user and is used for appointing a video output device needing to output video data, and controlling the video output device needing to output the video data to synchronously play video data to be played with the output control device according to the control command; and the video output device is used for playing the video data to be played under the control of the output control device.

Description

technical field [0001] The invention relates to the technical field of multimedia information output, in particular to a video data output system, method and output control device. Background technique [0002] When the technicians in the field of radio and television browse or review the content of TV programs, they need to selectively output the video data corresponding to the TV programs to be browsed or reviewed to multiple video monitors, and often need to control them according to the actual situation. The output status of video data on each video output device, such as controlling the stop or normal play of video data on a specified monitor. Please refer to the attached figure 1 , the basic principle of the prior art scheme is: [0003] The input terminal of the video distributor reads the video data to be output, and when the video data is output, the video signal in the video data to be output is equally divided into multiple output video signals by the video dist...
