Increasing decoding throughput of intra-coded blocks

A method of encoding video data, the method comprising:

• setting, by one or more processors implemented in circuitry, a picture size of a picture, wherein setting the picture size comprises applying a picture size restriction to set a width of the picture and a height of the picture to each be a respective multiple of a maximum of 8 and a minimum coding unit size for the picture;
• partitioning, by one or more processors implemented in circuitry, the picture into a plurality of blocks;
• generating, by the one or more processors, a prediction block for a block of the plurality of blocks;
• generating, by the one or more processors, a residual block for the block based on differences between the block and the prediction block;
• and
• encoding, by the one or more processors, the residual block.

A device for decoding video data, the device comprising one or more processors implemented in circuitry and configured to:

• determine a picture size of a picture according to a picture size restriction so as to determine a width of the picture and a height of the picture to each be a respective multiple of a maximum of 8 and a minimum coding unit size for the picture;
• determine a partition of the picture into a plurality of blocks;
• generate a prediction block for a block of the plurality of blocks;
• decode a residual block for the block;
• and
• combine the prediction block and the residual block to decode the block.
