Problems solved by technology

When the encoder accepts data for encoding, due to various reasons, the data received by the encoder will cause delay due to buffer overflow, or due to the slow encoding speed, it will inevitably cause image loss during encoding. The problem of frame and blurred screen, and this image problem is irrecoverable, affects the quality of monitoring, loses the original intention and effect of video monitoring, and makes real-time monitoring an empty talk

Embodiment Construction

[0016] The invention provides a method for processing image coding frame loss and blurred screen delay of an H.264 video encoder using video (television) as a display terminal, especially the case of multi-channel CIF format coding delay.

[0017] By adopting the method of the present invention, the following steps can be taken: 1. Reserving the latest normal I frame as a P frame encoding reference to correct image frame loss and blurred screen. 2. If in the first method, the last normal I frame is retained for too long, then use the latest YUV data in the cache to recompose the I frame, and use this latest I frame as the P frame encoding reference frame, and convert the generated The blurred screen, frame loss and delay are controlled within an acceptable range to ensure the normality and work efficiency of real-time video surveillance.

[0018] The embodiment that the present invention adopts is:

[0019] Step 1. Set up a buffer on the encoder side to receive image data.

Abstract

The invention provides a processing method for splash screen caused by picture coding frame loss, mainly comprising the following steps: firstly, keeping the nearest normal frame I as a frame P coding reference to correct the frame loss and the splash screen of a picture, and secondly, In the first method, if the normal frame I is kept for too long, the frame I is reconstructed by utilizing the newest YUV (luma and chroma) data in a buffer memory, and the newest frame I is used as a frame P coding reference frame. In the invention, the generated splash screen, the frame loss and time delay are controlled in an acceptable range, so as to ensure the normal working and working efficiency of real-time video monitoring.

Description

technical field [0001] The invention relates to a method for processing image coding loss of frames and artifacts of an H.264 video encoder using a video (television) as a display terminal, in particular to the processing of multi-channel CIF format image encoding loss of frames and artifacts. Background technique [0002] With the rapid development of Internet and multimedia technology, the network real-time transmission of video has become one of the research hotspots of network application. The H.264 standard has become the main format and standard for multimedia transmission on the Internet at present and in the next generation due to its high compression rate, high quality and low bit rate. Real-time video transmission requires a small transmission delay and a low packet loss rate. As a H.264-based video server, after the front-end hardware encoding, the image data packets are transmitted through the network to the terminal for encoding and displaying. When the encode...
