Abstract
The present disclosure provides a display control method and a display control apparatus, a video processing apparatus and a display system. The display control method includes the following steps: determining whether a received switching instruction is a multi-image display instruction; extracting a plurality of video identifiers from the multi-image display instruction in a case where the switching instruction is the multi-image display instruction; multiplexing input videos of a plurality of channels corresponding to the plurality of the video identifiers to generate a first video; and sending the first video to a display apparatus for multi-image display.
Claims6
A display control method performed by a display control apparatus, comprising:
- determining whether a received switching instruction is a multi-image display instruction;
- extracting a plurality of video identifiers from the multi-image display instruction in a case where the switching instruction is the multi-image display instruction;
- multiplexing input videos of a plurality of channels corresponding to the plurality of the video identifiers to generate a first video;
- sending the first video to a display apparatus for multi-image display;
- reading a pre-stored configuration file in a case where the display control apparatus is started, wherein the pre-stored configuration file corresponds to a display mode of the display control apparatus before a latest shutdown;
- detecting whether a current video input status is consistent with a video input status before the latest shutdown;
- determining whether there is currently an input video of only one channel in a case where the current video input status is inconsistent with the video input status before the latest shutdown;
- determining whether a display mode before the latest shutdown is a full-screen display mode in a case where there are currently input videos of a plurality of channels;
- multiplexing the current accessed videos to generate a second video in a case where the display mode before the latest shutdown is a preview mode, wherein resolution of the second video is smaller than a preset threshold;
- and
- sending the second video to a display apparatus for previewing.
