DM8168 encode/decode capability in DVRRDk 4.0 NVR specifications:8ch 1080P30 decode?

I read a doc,<DVRRDk V4.1 NVR Spec>.It says:

decode performance:

8ch 1080P30 or

16ch 720P30.

It exceeds 3ch 1080P60 capability.

What's the case?

    Only 6 channel of 1080p30 decode is possible. The 8 channel mentioned is a mistake. It is possible to decode 8 channel 1080p30 for low complexity streams if tiler is enabled for decoder output buffers but enabling tiler imposes some restrictions. Maximum of only 128MB luma buffers is possible for allocation when using tiled memory. Also deleting and creating tiled memory causes more memory fragmentation and can result in decoder create failing due to memory allocation issues.
