METHOD AND DEVICE FOR PROCESSING VIDEO SIGNAL BY USING INTER PREDICTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18224481 titled 'METHOD AND DEVICE FOR PROCESSING VIDEO SIGNAL BY USING INTER PREDICTION

Simplified Explanation

This patent application describes methods and devices for decoding video signals using inter prediction. The goal is to improve compression performance and reduce computation time. Here are the key points:

  • The method involves constructing a reference picture list for a current picture in the video signal.
  • The reference picture list is used for performing prediction for the current picture.
  • If the first entry in the reference picture list is a short-term reference picture (STRP), the method obtains the picture order count (POC) difference between the first entry and another picture.
  • If the second entry in the reference picture list is a long-term reference picture (LTRP), the method obtains the POC modulo value of the picture related to the second entry.
  • By generating the reference picture list in this simplified and effective manner, the compression performance of the video signal can be increased.
  • Additionally, the computation time required for decoding the video signal can be decreased.


Original Abstract Submitted

Embodiments of the disclosure provide methods and devices for decoding video signals using inter prediction. According to an embodiment of the disclosure, a method for processing a video signal comprises constructing a reference picture list of a current picture in the video signal and performing a prediction for a current picture by using the reference picture list, wherein constructing the reference picture list comprising, if a first entry of the reference picture list corresponds to a short-term reference picture (STRP), obtaining a picture order count (POC) difference between a picture related to the first entry and another picture, and if a second entry of the reference picture list corresponds to a long-term reference picture (LTRP), obtaining a POC modulo value of a picture related to the second entry. A reference picture list for identifying a picture may be generated in a simplified and effective manner. Thus, the compression performance may be increased, and the computation time may be decreased.
