Detailed Description
The present invention will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
Example 1
The invention provides an ultra-low time delay image coding system, which is shown in figure 1 and comprises a transmitting end and a receiving end.
The sending end is used for encoding and compressing the image and then transmitting the image through a network; and the receiving end is used for receiving the coded and compressed image data through a network and coding and decompressing the coded and compressed image data to obtain an image.
Specifically, when each frame image is encoded and compressed at a transmitting end, the frame image is firstly divided to obtain a plurality of block images, then each block image is encoded and compressed, and finally each encoded data after the encoding and compression is transmitted through a network.
The invention divides a frame of image to form a plurality of small block images, so that the small block images have small data volume relative to the original image, occupy less resources during image coding compression and transmission, and are beneficial to improving transmission efficiency and reducing transmission delay.
More preferably, when the invention divides a frame of image, the frame of image is divided into a plurality of block images with equal size, so as to ensure the size balance of data packets corresponding to each block image, and avoid the impact of oversized data packets on a network.
In order to ensure that several block images are integrated into the original image later, the order of each block image needs to be recorded when each block image is subjected to encoding compression. The order of block images refers to the order of block images when dividing the images.
Meanwhile, when each block image after encoding and compression is packed, the size balance of each data packet needs to be ensured, the impact of the oversized data packet on a network is avoided, and the stability of the network can be effectively ensured by balanced data transmission.
For the receiving end, after each data packet is received, each data packet is parsed to obtain encoded data. Meanwhile, since each frame of image is segmented at the transmitting end, all data packets of each frame of image need to be received and analyzed at the receiving end to obtain all encoded data of each frame of image, namely, the encoded data of each block of image after each frame of image is segmented.
In this way, the encoded data of all the block images of each frame image are integrated and decompressed to obtain the corresponding frame image. Meanwhile, when the receiving end integrates and decompresses all the coded data of one frame of image, the GPU is adopted to replace a CPU, so that the coding and decompressing efficiency is further improved, the CPU is released, and the overall performance is improved. That is, the invention divides the image to form small images at the transmitting end, then encodes each small image, thus improving the encoding efficiency of the image, shortening the encoding time, avoiding the impact of large data packet to the network when compressing and packing the encoded data, ensuring the stability of the network, improving the efficiency of data transmission, reducing the time of data transmission, greatly improving the decoding speed and releasing the CPU and improving the overall performance when using GPU decoding at the receiving end compared with traditional CPU decoding.

step S11, a frame image is acquired and divided to form a plurality of block images.
In this embodiment, each time an image of one frame is received, processing is performed respectively, that is, when an image of one frame is received, the image of one frame is divided into a plurality of block images, and processing is continued after processing of the image of the previous frame is completed.
And step S12, encoding and compressing each block image according to the sequence of a plurality of block images of one frame image to obtain corresponding encoded data.
The invention divides the image to be transmitted with large data volume to form the block image with small data volume, and then respectively codes and compresses each block image, thereby improving the coding efficiency and shortening the coding time. For a person skilled in the art, for an image, the larger the data amount, the more time it takes to encode the image, which is significantly longer than the encoding time of a plurality of small images of the same data amount. Therefore, the invention can greatly improve the coding efficiency and shorten the coding time by dividing the large image into small images and then coding.
Meanwhile, in the practical application process, for example, a plurality of parallel processes are adopted to encode each block image, so that the encoding efficiency can be further improved.
In addition, in order to ensure the integration of several block images later, when each block image is encoded, the order of each block image needs to be recorded.
Step S13, each coded data is packed to form a corresponding data packet, and each data packet is sent out through a network.
When data is sent out through a network, the data is required to be packaged according to a transmission protocol to form a data packet and then sent out.

Further, in the dividing step: when the current frame image is divided when there are a plurality of block images, the current frame image is divided into a plurality of block images with equal size.
Further, the processor, when executing the image encoding program, implements the steps of: judging: and returning to the segmentation step to continuously receive the next frame image and recording the next frame image as the current frame image after the current frame image is successfully encoded.
