Please read the following table in Markdown format and then answer the question according to the table. Table cells in one row are seperated by '|', and different rows are seperated by '
'.

Table:
| Abbr. | Name | Picture Coding Types | Chroma Format | Aspect Ratios | Scalable modes | Intra DC Precision |
| --- | --- | --- | --- | --- | --- | --- |
| SP | Simple profile | I, P | 4:2:0 | square pixels, 4:3, or 16:9 | none | 8, 9, 10 |
| MP | Main profile | I, P, B | 4:2:0 | square pixels, 4:3, or 16:9 | none | 8, 9, 10 |
| SNR | SNR Scalable profile | I, P, B | 4:2:0 | square pixels, 4:3, or 16:9 | SNR (signal-to-noise ratio) scalable | 8, 9, 10 |
| Spatial | Spatially Scalable profile | I, P, B | 4:2:0 | square pixels, 4:3, or 16:9 | SNR- or spatial-scalable | 8, 9, 10 |
| HP | High profile | I, P, B | 4:2:2 or 4:2:0 | square pixels, 4:3, or 16:9 | SNR- or spatial-scalable | 8, 9, 10, 11 |
| 422 | 4:2:2 profile | I, P, B | 4:2:2 or 4:2:0 | square pixels, 4:3, or 16:9 | none | 8, 9, 10, 11 |
