METHOD AND APPARATUS FOR DETERMINING REFERENCE PICTURE SET OF IMAGE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17956203 titled 'METHOD AND APPARATUS FOR DETERMINING REFERENCE PICTURE SET OF IMAGE
Simplified Explanation
The patent application describes a method for determining a set of reference pictures used in predictive decoding of a current picture. Here are the key points:
- The method can determine the reference picture set (RPS) based on either the picture order count (POC) values of the current and previous pictures, or based on an index of a reference RPS.
- The reference RPS is a pre-defined set of reference pictures that is used to determine the RPS.
- The method also considers a delta RPS, which is the difference between the POC value of a reference picture included in the reference RPS and the POC value of a reference picture included in the RPS.
- The RPS is determined based on the value of a flag, which indicates whether the RPS is determined using POC values or an index of a reference RPS.
Potential applications of this technology:
- Video compression and encoding: The method can be used in video codecs to improve the efficiency of predictive decoding, resulting in better compression and reduced bandwidth requirements.
- Video streaming: By optimizing the reference picture selection, this method can enhance the quality and smoothness of video streaming services.
Problems solved by this technology:
- Efficient reference picture selection: The method provides a systematic approach to determine the reference picture set, which helps in improving the accuracy and efficiency of predictive decoding.
- Reduced decoding complexity: By selecting the most appropriate reference pictures, the method can reduce the computational complexity of the decoding process.
Benefits of this technology:
- Improved video quality: By selecting the most suitable reference pictures, the method can enhance the quality of decoded video frames, resulting in a better viewing experience.
- Reduced bandwidth requirements: The optimized reference picture selection can lead to better compression, allowing for reduced bandwidth usage in video transmission.
- Lower decoding complexity: The method helps in reducing the computational complexity of decoding, making it more efficient and faster.
Original Abstract Submitted
A method of determining a reference picture set (RPS), which is a set of reference pictures used in predictive decoding of a current picture that is to be decoded includes: obtaining a flag indicating whether the RPS is determined based on picture order count (POC) values of the current picture and a previous picture or whether the RPS is determined based on an index of a reference RPS, which is an identification value of the reference RPS that is one of pre-defined RPSs and is referred to in determining the RPS, and a delta RPS that is a difference value between a POC vale of a reference picture included in the reference RPS and a POC value of a reference picture included in the RPS; and determining the RPS according to a value of the flag.
