Block Vector Difference (BVD) Coding - A simplified explanation of the abstract
This abstract first appeared for US patent application 18491465 titled 'Block Vector Difference (BVD) Coding
The abstract of the patent application describes a method for encoding video parameters using an entropy code, where a codeword consists of a prefix part indicating a range of values and a suffix part indicating a specific value within that range. Efficient coding is achieved by reducing the lengths of suffix parts associated with selected prefix parts, based on the maximum possible value of the video parameter.
- Video parameters are represented as codewords encoded using an entropy code.
- Codewords consist of a prefix part indicating a range of values and a suffix part indicating a specific value within that range.
- Efficient coding is achieved by reducing the lengths of suffix parts for selected prefix parts.
- Prefix parts are selected based on the maximum possible value of the video parameter.
Potential Applications: - Video compression technologies - Image processing applications - Data transmission systems
Problems Solved: - Efficient encoding of video parameters - Reduction of data size in video processing - Improved compression techniques
Benefits: - Enhanced video quality - Reduced data transmission bandwidth - Improved storage efficiency
Commercial Applications: Title: Enhanced Video Compression Technology for Data Transmission Systems This technology can be used in video streaming services, surveillance systems, and video conferencing platforms to improve data compression and transmission efficiency.

Frequently Updated Research: Ongoing research in video compression algorithms and entropy coding techniques may further enhance the efficiency and performance of this technology.
Original Abstract Submitted
A video parameter (e.g., a block vector difference (BVD)) may be represented as a codeword encoded using an entropy code. The codeword may comprising a prefix part and a suffix part. A prefix part may indicate a range of values, and a suffix part may indicate a specific value within the range. Efficient entropy coding may be achieved by reducing lengths of suffix parts associated with one or more selected prefix parts. The prefix parts may be selected based on a maximum possible value of the video parameter.
