Example Embodiment

[0011] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other if there is no conflict.

[0012] figure 1 Shown is a flowchart of a multi-picture synthesis method according to a preferred embodiment of the present invention. Such as figure 1 As shown, the multi-picture synthesis method provided by the preferred embodiment of the present invention includes steps 101-106.

[0013] In step 101: the controller sends the to-be-obtained video stream information to the input stream control device.

[0014] Among them, the video stream information to be obtained carries video stream address information, video stream format information, and video stream size information.

[0015] Among them, the video stream format includes RGB32, RGB24, Y8, YUY2, NV12, AYUV, YV12, I420, Y41P, VYUY, YUYV, ...

Abstract

The invention provides a multipicture synthesizing method and system. The method comprises the following steps that input stream control equipment obtains video streams; a controller sets initial input parameter data and target output parameter data, sends the initial input parameter data to the input stream control equipment and sends the target output parameter data to output stream control equipment, wherein the initial input parameter data and target output parameter data correspond to the video streams ; the input stream control equipment packages the obtained video streams and the obtained initial input parameter data, a first data package is obtained and the first data package is sent to image processing equipment; the output stream control equipment packages the target output parameter data, a second data package is obtained and the second data package is sent to the image processing equipment; after the image processing equipment receives the first data package and the second data package, image processing is conducted and an image processing result is obtained.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a multi-picture synthesis method and system. Background technique [0002] With the continuous development of display technology, there are various requirements for displaying images. In particular, displaying multiple input video signals on one display makes it possible to display multi-screen image information on limited display devices. [0003] The existing multi-channel video signal picture synthesis needs to process the format, size, resolution and other parameters of each video signal separately, and then display the multiple video signals in the corresponding areas of the picture. The processing and output of the video are independent, and a large amount of resources are required in the process of processing and outputting multiple videos, so the performance requirements of the hardware device are relatively high. At the same time, when it is necessary to chan...
