ADAPTIVELY DERIVING RICE PARAMETER VALUES FOR HIGH BIT-DEPTH VIDEO CODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18334308 titled 'ADAPTIVELY DERIVING RICE PARAMETER VALUES FOR HIGH BIT-DEPTH VIDEO CODING
Simplified Explanation
The abstract describes a device for binarizing video data using a specific technique called Rice parameter selection. Here are the key points:
- The device includes a memory to store video data and one or more processors to perform calculations and operations.
- The device calculates the sum of absolute values of neighboring coefficients to a current coefficient in a block of video data.
- It derives a shift value from this sum and normalizes it.
- The device determines a Rice parameter using the normalized sum.
- Finally, it binarizes or inverse binarizes the current coefficient using the Rice parameter.
Potential applications of this technology:
- Video compression: The device can be used in video compression algorithms to efficiently encode high bitdepth video data.
- Video streaming: By improving the binarization process, the device can enhance the encoding and decoding of video streams, leading to better quality and reduced bandwidth requirements.
- Video editing: The device can be utilized in video editing software to optimize the processing of video data during editing operations.
Problems solved by this technology:
- Inefficient binarization: Traditional binarization techniques may not be suitable for high bitdepth video data, leading to suboptimal compression and encoding results.
- Inaccurate Rice parameter selection: Selecting an inappropriate Rice parameter can result in inefficient encoding and decoding of video data.
Benefits of this technology:
- Improved compression efficiency: By selecting the Rice parameter more accurately, the device can achieve better compression ratios for high bitdepth video data.
- Enhanced video quality: The device's binarization technique can help preserve the quality of video data during compression and decompression processes.
- Reduced bandwidth requirements: Efficient encoding and decoding of video data can lead to lower bandwidth requirements for video streaming and transmission.
Original Abstract Submitted
An example device for binarizing video data includes a memory configured to store video data; and one or more processors implemented in circuitry and configured to: calculate a local sum of absolute values (locSumAbs value) of neighboring coefficients to a current coefficient of a current block of video data; derive a shift value from the locSumAbs value; normalize the locSumAbs value using the shift value; determine a Rice parameter using the normalized locSumAbs value; and binarize or inverse binarize the current coefficient using the Rice parameter. In this manner, these techniques may allow for more appropriate Rice parameter value selection when binarizing high bitdepth data in conjunction with performing context-adaptive binary arithmetic coding (CABAC).
