Embodiment Construction

[0034] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The present invention aims at the development of display devices in the existing video monitoring system towards high-definition display devices, while the existing video decoder can only decode one SD video stream, and display one SD image or one SD image after zooming in on the HD display device Due to the shortcomings of high-definition images, a video decoding method is provided for simultaneously decoding multiple channels of standard-definition video streams and combining them into one output channel of high-definition video images. Using this video decoding method, one video decoder can correspond to multiple video encoders, and multiple video images can be displayed simultaneously by using one high-definition display device, which not only improves the utilization rate of the display device, bu...

Abstract

The invention discloses a video decoding method, a video decoder and a video monitoring system. The video decoding method comprises the following steps: judging the type and the quantity of received video streams; identifying each path of the video streams when the received video streams are a plurality of paths of standard definition video streams; decoding each path of the video streams in a parallel way; and combining the plurality of paths of decoded standard definition video images into a path of high definition video image for outputting. By using the video decoding method of the invention, one decoder can process the plurality of paths of the standard definition video streams at the same time and combine the plurality of paths of the standard definition video images into a path of the high definition video image for outputting; and high definition display equipment is sufficiently used for improving the definition of displayed video images and a video display effect on the premise of avoiding image distortion to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video decoding method, a video decoder and a video monitoring system. Background technique [0002] The video surveillance system is an important part of the security system widely used in various industries, and it is also an important part of the intelligent transportation system. A video surveillance system with powerful functions and excellent performance can not only effectively monitor the scene and record evidence, but also help users analyze events with the help of video analysis technology. A video surveillance system generally includes a camera, a video encoder, a video decoder, and a display device. Wherein, the video image collected by the camera is compressed and encoded by the video encoder, and then transmitted to the video decoder; the video decoder decodes the received video stream, and then outputs the video image to the display device for display. ...
