APPARATUS, A METHOD AND A COMPUTER PROGRAM FOR VIDEO CODING AND DECODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18492501 titled 'APPARATUS, A METHOD AND A COMPUTER PROGRAM FOR VIDEO CODING AND DECODING
Simplified Explanation
The abstract describes a method for encoding a bitstream with multiple layers and different prediction types between layers.
- Encoding a bitstream with a base layer, a first enhancement layer, and a second enhancement layer.
- Indicating both the base layer and the first enhancement layer used for prediction for the second enhancement layer in the bitstream.
- Encoding an indication of a first set of prediction types applicable from the base layer to the second enhancement layer, which is a subset of all available prediction types between layers.
- Encoding an indication of a second set of prediction types applicable from the base layer or the first enhancement layer to the second enhancement layer, which is a subset of all available prediction types between layers.
Potential applications of this technology:
- Video encoding and decoding systems
- Multimedia streaming services
- Virtual reality and augmented reality applications
Problems solved by this technology:
- Efficient encoding and decoding of multi-layered video content
- Improved prediction accuracy between layers
- Enhanced video quality and compression ratios
Benefits of this technology:
- Better utilization of available prediction types
- Reduced bandwidth and storage requirements
- Enhanced user experience with high-quality video playback
Original Abstract Submitted
A method comprising encoding a bitstream comprising a base layer, a first enhancement layer and a second enhancement layer; encoding an indication of both the base layer and the first enhancement layer used for prediction for the second enhancement layer in the bitstream; encoding, in the bitstream, an indication of a first set of prediction types that is applicable from the base layer to the second enhancement layer, wherein the first set of prediction types is a subset of all prediction types available for prediction between layers, and encoding, in the bitstream, an indication of a second set of prediction types that is applicable from the base layer or the first enhancement layer to the second enhancement layer, wherein the second set of prediction types is a subset of all prediction types available for prediction between layers.
