METHOD FOR GENERATING VIDEO- AND AUDIENCE-SPECIFIC ENCODING LADDERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240015302 titled 'METHOD FOR GENERATING VIDEO- AND AUDIENCE-SPECIFIC ENCODING LADDERS
Simplified Explanation
The patent application describes a method for optimizing video encoding based on the properties of a video segment and the distribution of audience bandwidths. Here are the key points:
- Extracting a set of video features that represent properties of a video segment.
- Generating a set of bitrate-resolution pairs based on the video features. Each pair defines a bitrate and a resolution that maximizes the quality score of the encoded video segment.
- Accessing a distribution of audience bandwidths.
- Selecting a top bitrate-resolution pair that represents the highest quality option.
- Selecting a bottom bitrate-resolution pair that represents the lowest quality option.
- Selecting a subset of bitrate-resolution pairs based on the distribution of audience bandwidths. This subset includes bitrates lower than the top bitrate and higher than the bottom bitrate.
- Generating an encoding ladder for the video segment, which includes the top bitrate-resolution pair, the bottom bitrate-resolution pair, and the subset of bitrate-resolution pairs.
Potential applications of this technology:
- Video streaming platforms can use this method to optimize video quality based on the available bandwidth of the audience.
- Content creators can ensure their videos are encoded at the optimal quality for different bandwidth conditions.
- Video conferencing systems can dynamically adjust the video quality based on the network conditions of the participants.
Problems solved by this technology:
- Ensures that video encoding is optimized for different bandwidth conditions, providing the best possible quality to viewers.
- Eliminates the need for manual adjustment of video encoding settings based on audience bandwidth.
Benefits of this technology:
- Improved video quality for viewers, as the encoding is optimized based on the available bandwidth.
- Efficient use of network resources, as the encoding ladder includes a range of bitrates that cater to different bandwidth conditions.
- Simplifies the video encoding process for content creators and streaming platforms.
Original Abstract Submitted
a method including: extracting a set of video features representing properties of a video segment; generating a set of bitrate-resolution pairs based on the set of video features, each bitrate-resolution pair in the set of bitrate-resolution pairs defining a bitrate and defining a resolution estimated to maximize a quality score characterizing the video segment encoded at the bitrate; accessing a distribution of audience bandwidths; selecting a top bitrate-resolution pair in the set of bitrate-resolution pairs; selecting a bottom bitrate-resolution pair in the set of bitrate-resolution pairs; selecting a subset of bitrate-resolution pairs in the set of bitrate-resolution pairs based on the distribution of audience bandwidths, the subset of bitrate-resolution pairs defining bitrates less than the top bitrate and greater than the bottom bitrate; and generating an encoding ladder for the video segment comprising the top bitrate-resolution pair, the bottom bitrate-resolution pair, and the subset of bitrate-resolution pairs.
