Meaning of JSVM in COMPUTING
JSVM is a video compression technology that combines the advantages of Discrete Cosine Transform (DCT) and Wavelet Transform (WT) coding to achieve high compression efficiency. It employs a hierarchical coding structure that allows for the efficient scalability of encoded bitstreams. This scalability enables the adaptation of video content to different network conditions and display devices.
Functionality
- DCT-based Coding: JSVM utilizes DCT to compress the residual signal obtained from subtracting the predicted values from the original video signal.
- WT-based Coding: WT is applied to the prediction residue to further enhance compression efficiency.
- Hierarchical Coding Structure: The compressed video is organized into a hierarchy of layers. Each layer contains a subset of the video information, allowing for progressive decoding and adaptation to varying bandwidth and device capabilities.
Advantages
- High Compression Efficiency: JSVM achieves significant compression gains compared to previous video coding standards.
- Scalability: It supports both spatial and temporal scalability, enabling the adaptation of video content to different screen sizes and transmission rates.
- Error Resilience: JSVM incorporates error resilience techniques to mitigate the effects of transmission errors and ensure robust video delivery.
