Description
Technical Field
The invention relates to the technical field of audio and video transmission, in particular to a low-code-stream high-definition video processing terminal and a video monitoring system.
Background
With the high-speed development of computer technology, the information age gradually comes, audio and video data are gradually digitalized in the application process, and the development of digitalized audio and video promotes the rapid development of the video media industry; however, in practical situations, due to the increasing parameters of digital audio and video, the amount of data formed is huge, and the storage capacity and channel capacity required by digital audio and video transmission are also greatly increased, for example, a DVD can only store uncompressed digital video of several seconds, and a megabyte of digital television video with bandwidth of one second requires about 4 minutes, which leads to significant increase of communication cost. The advent of compression technology has attracted world attention, received much attention, and has a significant effect on solving the above-mentioned problems. For example, it has been found that at least 4:1 compression can be performed on sound under lossless conditions, leaving all information with only 1/4 digital quantities; in the video field, researches find that the compression ratio can reach hundreds of times, and the storage capacity of the digital audio and video and the channel capacity during transmission are greatly reduced.
The current remarkable application of the digital audio and video is a video communication technology, the video communication integrates a network, video and audio, and the network is also required to be considered in the communication process except for adopting a compression technology to obtain clear and flow field pictures. The network bandwidth is the basis for realizing video communication, because different network bandwidths are configured according to different data volume transmission requirements, and the larger the data volume is, the larger the generated flow is, resulting in the larger bandwidth required for transmission. Therefore, if there is not enough network bandwidth, the phenomena of picture jitter and sound noise will occur during video communication, and it is not possible to ensure that video communication is clear and synchronous. In order to guarantee the video communication, some enterprises adopt a private network to guarantee the network bandwidth required by the video communication, but the private network has high cost. In order to carry out video communication or remote control clearly and smoothly, the contradiction between real-time high-definition audio and video and the network bandwidth is solved by means of the latest video coding technology, and high-definition smooth pictures in the video communication or video monitoring process are realized by reducing transmission flow and data volume.

Based on the network bandwidth in the limited area when some existing enterprises and public institutions work, the monitoring system arranged in the limited area or the network crystal type video communication is adopted, data traffic exceeding the limitation of the network bandwidth cannot be transmitted, and otherwise, the phenomena of picture jitter, sound noise, video delay and the like can occur. The invention aims to reduce the flow of the acquired audio and video in the transmission process on the premise of ensuring the acquisition of high-definition video images by means of the latest video coding technology, and is suitable for the application environment with limited bandwidth.
The low-bit-stream high-definition video processing terminal and the video monitoring system disclosed by the invention are further specifically described below with reference to specific embodiments.
With reference to fig. 1, the low-bit-stream high-definition video processing terminal disclosed by the present invention includes the following program modules: the device comprises a dividing module, a video acquiring module, a judging and generating module, a first compression acquiring module and a sending module; the above modules are respectively used for realizing the following functions, including: the dividing module is used for dividing the monitoring area into a plurality of monitoring blocks; the video acquisition module is used for acquiring wireless field intensity information of a monitoring area and video stream data of all monitoring blocks, and recording the acquired video stream data of any monitoring block as a first video stream; the judgment generation module is used for respectively judging the image states of the continuous video frames of the first video stream according to the edge filtering algorithm and the video optical flow algorithm to generate a second video stream; the first compression obtaining module is used for recompressing the second video stream according to the wireless field intensity information and the H.264 or H.265 standard to obtain a third video stream; and the sending module is used for sending the third video stream to the remote control center so that the remote control center can call the third video stream, decode the third video stream according to the H.264 or H.265 standard and display the monitoring video of each monitoring block according to the first identifier, the second identifier or the third identifier.
Specifically, the image states of the consecutive video frames determined by the determination generation module in the specific implementation include motion and relative stillness, that is, two states may exist in the first video stream of any monitoring block; that is, when the continuous video frames of any first video stream are motion change videos, the current first frame of any first video stream is stored as a high-definition image, and other continuous video frames are encoded according to the H.264 or H.265 standard and then are added with a first identifier to generate a second video stream; when continuous video frames of a first video stream are repeated images, storing the current first frame of the first video stream as a high-definition image, and adding a second identifier after other continuous video frames are coded according to the H.264 or H.265 standard to generate a second video stream; when continuous video frames of at least two first video streams are repeated images, merging the first video streams according to a frame sequence corresponding mode, storing the first frames of the merged video streams as high-definition images, and adding a third identifier after other continuous video frames are encoded according to the H.264 or H.265 standard to generate a second video stream; the first video stream, which is determined to be motion change video in the latter two cases, still employs the first identification tag. Namely, the judgment generation module carries out primary coding compression on the continuous video frames of the first video stream except for storing the first frame of high-definition pictures, and removes redundant data. Due to the fact that the mode of processing the monitoring blocks respectively is adopted, videos of the relative static monitoring blocks are combined, transmission of repeated image data is reduced, the detection blocks in the motion state are screened and displayed, and data volume of the videos is greatly reduced.
In the process of recompression executed by the first compression acquiring module, due to the limitation of the wireless field strength information of the monitoring area network, such as the network bandwidth, the second video stream with the overlarge flow rate cannot be transmitted in the flow field under the network bandwidth, so that the first compression acquiring module encodes and compresses the second video stream by adopting the h.264 or h.265 standard, and the third video stream output by the first compression acquiring module is a video which meets the requirement of smooth and high-definition playing under the network bandwidth.
When the low-code-stream high-definition video processing terminal is used specifically, the low-code-stream high-definition video processing terminal further comprises a mobile phone and a compression processing module for monitoring the audio in a region, and therefore the low-code-stream high-definition video processing terminal at least comprises an audio acquisition module and a second compression acquisition module.
