METHODS PROVIDING ENCODING AND/OR DECODING OF VIDEO USING REFERENCE VALUES AND RELATED DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18524498 titled 'METHODS PROVIDING ENCODING AND/OR DECODING OF VIDEO USING REFERENCE VALUES AND RELATED DEVICES

Simplified Explanation

The abstract describes a method for decoding an encoded video sequence by calculating reference values based on adjacent blocks of an image and using interpolation to generate filtered pixel values for a line of pixels between the blocks.

• First and second adjacent blocks of an image are provided.
• A line of pixels across the boundary between the blocks is defined.
• A first reference value is calculated based on a pixel from the first block.
• A second reference value is calculated based on a pixel from the second block.
• Filtered pixel values for each pixel on the line are calculated using interpolation.
• Filtered blocks are generated using the filtered pixel values.
• A decoded video sequence is generated based on the filtered blocks.

Original Abstract Submitted

An encoded video sequence including a plurality of images may be decoded. First and second adjacent blocks of an image of an encoded video sequence may be provided. A line of pixels including pixels of the first and second blocks may be defined extending across a boundary between the first and second blocks. A first reference value may be calculated based on a first pixel of the pixels from the first block. A second reference value may be calculated based on a second pixel of the pixels from the second block. Filtered pixel values for each pixel of the line of pixels between the first pixel and the second pixel may be calculated using interpolation based on the first and/or second reference values. Filtered blocks may be generated using the filtered pixel values, and a decoded video sequence may be generated based on the filtered blocks.
