Abstract

The embodiment of the invention discloses a video processing device, and the device comprises a control unit which is used for transmitting a mixed superposed processing signal; a zooming unit which is used for carrying out the image zooming of received multipath video signals, and obtaining multipath video data after zooming; a mixed superposing unit which is used for carrying out the image mixed superposing of the multipath video data after zooming and the receiving of the mixed superposed processing signal, and obtaining multi-window mixed superposed video data; and an output interface which is used for outputting multi-window mixed superposed video data through a single channel. Therefore, the device can achieve the multi-window frame display on a display screen. In addition, the embodiment of the invention also provides a multi-window frame display method, so as to make the display information of the display screen abundant.

Description

technical field [0001] The present invention relates to the technical field of display control, in particular to a video processing device and a multi-window image display method. Background technique [0002] The display system can display a single-channel video input image, and can also display multiple sets of video input images simultaneously, and these video input images can be tiled to form a multi-grid, or can be overlapped and displayed in layers. This display effect is mostly used in application scenarios such as monitoring systems, outdoor or indoor screen advertisements, and stage screen displays. [0003] The traditional single output port-multi-window display system generally only has two scaler (Scaler) algorithm modules inside the dedicated processor chip. If more than two windows are output and displayed on a single output port, multi-chip dedicated processing is required. The processor chips are cascaded and it is also necessary to configure image mixing an...
