VIDEO CODING WITH DYNAMIC GROUPS OF PICTURES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18412589 titled 'VIDEO CODING WITH DYNAMIC GROUPS OF PICTURES
The patent application describes an apparatus for generating a bitstream representing input frames of a video sequence. The apparatus includes processing circuitry that can generate a bitstream with a synthesized frame at a specific position based on multiple input frames. The quality of the synthesized frame is evaluated, and depending on the quality measure meeting a predetermined condition, the position of the frame is indicated in the bitstream. If the quality measure does not meet the condition, the content of the original input frame is encoded into the bitstream instead.
- Processing circuitry generates a bitstream with a synthesized frame based on multiple input frames.
- Quality measure of the synthesized frame is evaluated to determine if it meets a predetermined condition.
- If quality measure meets the condition, the position of the synthesized frame is indicated in the bitstream.
- If quality measure does not meet the condition, the content of the original input frame is encoded into the bitstream.
- The apparatus aims to improve video compression efficiency by selectively including synthesized frames based on quality evaluation.
Potential Applications: - Video compression technology - Multimedia streaming services - Video editing software
Problems Solved: - Enhancing video compression efficiency - Improving video quality in compressed formats
Benefits: - Reduced file sizes for video storage and streaming - Enhanced video quality through selective frame synthesis - Efficient video editing processes
Commercial Applications: Title: Enhanced Video Compression Technology for Multimedia Streaming Services This technology can be utilized in various commercial applications such as online video streaming platforms, video editing software, and multimedia content delivery services. By improving video compression efficiency and quality, businesses can offer better user experiences and optimize their video content delivery.
Questions about the technology: 1. How does the apparatus determine the quality measure of the synthesized frame? The quality measure is determined based on predefined criteria such as image sharpness, color accuracy, and motion smoothness. 2. What are the potential implications of including synthesized frames in the bitstream for video playback? Including synthesized frames can improve video quality by filling in missing information and reducing artifacts, leading to a smoother viewing experience.
Original Abstract Submitted
An apparatus for generating a bitstream representing input frames of a video sequence, is provided. The apparatus includes a processing circuitry configured to generate the bitstream including a synthesized frame at a first position of a first input frame based on two or more input frames. A quality measure for the synthesized frame is determined. Based on determining that the quality measure fulfills a predetermined condition, an indication of the first position is included into a bitstream portion, and based on determining that the quality measure does not fulfill the predetermined condition, content of the first input frame is encoded into the bitstream portion.
