CHINESE PATENT FOR SALE – Method for coding video by using long-term reference frame, electronic equipment and system
his patent introduces a video coding method that uses long-term reference frames (LTRFs) to improve video compression efficiency and quality.
The method operates as follows:
- Acquiring a Video Frame
- The system captures a video frame for processing.
- Caching and Marking a Long-Term Reference Frame (LTRF)
- The video frame is stored and marked as a potential long-term reference frame.
- Comparing the Effectiveness of LTRF vs. Short-Term Reference Frames
- The system checks whether the LTRF is more relevant for encoding than a short-term reference frame.
- Encoding with the Best Reference Frame
- If the LTRF is more relevant, the system uses it for encoding.
- Otherwise, a short-term reference frame is used.
- Sending the Encoded Data to a Decoder
- The encoded data is transmitted to the decoding terminal.
- Receiving Feedback and Updating the LTRF
- The system updates the active LTRF based on feedback from the decoder.
