| 27:16 | MEMSIZEY | R/W | 0h | Number of lines of the video picture Encoded value [from 1 to 4096] to specify the number of lines of the video picture in memory [program to value minus one] When predecimation is set, the value represents the size of the image after predecimation but the max size of the unpredecimated image size in memory is still bounded to 2exp[11] |

| 11:0 | MEMSIZEX | R/W | 0h | Number of pixels of the video picture Encoded value [from 1 to 4096] to specify the number of pixels of the video picture in memory [program to value minus one]. The size is limited to the size of the line buffer of the vertical sampling block in case the video picture is processed by the vertical filtering unit [program to value minus one]. When predecimation is set, the value represents the size of the image after predecimation but the max size of the unpredecimated image size in memory is still bounded to 2exp[11] |
