LOW- DELAY VIDEO ENCODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18573578 titled 'LOW- DELAY VIDEO ENCODING
The technology described in the patent application enables low-delay encoding of live video streams in multi-adapter systems. This involves encoding I-frames and subsets of P-frames of a live video signal using multiple graphics adapters and combining them into an output video bitstream.
- Frames of the live video signal are divided into subsets of P-frames on an alternating frame basis.
- The I-frame is copied from the first graphics adapter to the second graphics adapter before encoding the second subset of P-frames.
- Encoding of the subsets of P-frames occurs essentially in parallel using the two graphics adapters.
Potential Applications: - Live video streaming services - Video conferencing systems - Security surveillance systems
Problems Solved: - Reduced delay in encoding live video streams - Efficient utilization of multiple graphics adapters for encoding tasks
Benefits: - Improved video quality with reduced delay - Enhanced performance in multi-adapter systems - Increased flexibility in video encoding processes
Commercial Applications: - Video streaming platforms - Telecommunication companies - Security and surveillance industry
Questions about the technology: 1. How does the technology improve the efficiency of encoding live video streams? 2. What advantages does using multiple graphics adapters bring to the encoding process?
Original Abstract Submitted
Technology for low-delay encoding of live video streams in multi-adapter systems can include a host processor and memory comprising instructions which, when executed, cause a computing system to encode, via a first graphics adapter, an I-frame of a live video signal and a first subset of P-frames of the live video signal, encode, via a second graphics adapter, a second subset of P-frames of the live video signal, and combine the encoded video frames from the first adapter and the encoded video frames from the second adapter into an output video bitstream. Frames of the live video signal are divided into the first and second subsets of P-frames on an alternating frame basis, and the I-frame copied from the first graphics adapter to the second graphics adapter prior to encoding the second subset of P-frames, such that encoding the first and second subsets of P-frames occurs essentially in parallel.
