ENCODER, A DECODER AND CORRESPONDING METHODS USING COMPACT MV STORAGE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18483175 titled 'ENCODER, A DECODER AND CORRESPONDING METHODS USING COMPACT MV STORAGE

Simplified Explanation

The disclosed patent application describes a method for compressing motion vectors in video coding. Here is a simplified explanation of the abstract:

  • The method involves obtaining a temporal motion vector, which represents the motion of objects between consecutive frames in a video sequence.
  • A compressed motion vector is determined using a binary representation of the temporal motion vector. This compressed representation includes an exponent part and/or a mantissa part.
  • The exponent part consists of N bits, and the mantissa part consists of M bits. N is a non-negative integer, and M is a positive integer.
  • The compressed motion vector is then used for performing a temporal motion vector prediction (TMVP), which helps in predicting the motion of objects in subsequent frames.

Potential applications of this technology:

  • Video compression: This method can be used in video coding standards to compress motion vectors, reducing the amount of data required to represent motion information in videos.
  • Video streaming: By compressing motion vectors, the method can help in reducing the bandwidth required for streaming videos, allowing for smoother playback and faster transmission.

Problems solved by this technology:

  • Efficient compression: The method provides a way to compress motion vectors, which are essential for accurate motion estimation in video coding. By compressing these vectors, the method helps in reducing the storage and transmission requirements for video data.
  • Bandwidth optimization: Compressed motion vectors can help in optimizing bandwidth usage during video streaming, making it more efficient and reducing buffering times.

Benefits of this technology:

  • Improved video coding efficiency: By compressing motion vectors, the method allows for more efficient representation of motion information in videos, leading to better compression ratios and higher video quality.
  • Reduced storage and transmission requirements: Compressed motion vectors require less storage space and bandwidth, making it easier to store and transmit video data, especially in bandwidth-constrained environments.
  • Enhanced video streaming experience: By optimizing bandwidth usage, the method can improve the streaming experience by reducing buffering times and enabling smoother playback of videos.
