[M4IF Technotes] About Advanced Simple Profile tools

[Xue Xuhong]

Hi,
I am doing some work about Advanced Simple Profile(ASP), I know three tools
are used in ASP,they are:
1)Interlace
2)GMC
3)1/4-pel MC
I wonder if there are bitstream files that only used Interlace tool, only
GMC tool, or only 1/4-pel MC tool?
That is, should the three tools must be used together to implement ASP, they
can not be used separately?
Thank you.
Regards,
