SCANNING ORDERS FOR NON-TRANSFORM CODING

摘要

Non-transform blocks of video content may be coded by selectively changing a scanning order. In some implementations, an encoder or decoder may perform a scanning process on a block according to a scanning order. When the block has not been transformed, the encoder or decoder may selectively change the scanning order to a different order. For example, if the block is associated with a particular type of prediction, the scanning order may be changed to a different order. In another example, if the non-transform block has a size that is smaller than a predetermined size, the scanning order may be changed to a different order.

主权项

1. A method comprising:
identifying, by a computing device, a scanning order for scanning a first block, the first block being associated with a transform coding mode; identifying, by the computing device, a second block that is associated with a non-transform coding mode, the second block having at least one characteristic that is the same as a characteristic of the first block; determining to scan the second block according to a different scanning order than the scanning order for scanning the first block, the determining being based on at least one of a prediction mode associated with the second block or a size of the second block; and scanning, by the computing device, the second block according to the different scanning order.
