[M4IF Technotes] Downsample and Upsample filters

[Yossi Shain]

Hello,
I am trying to find information on downsample and upsample filters for YUV.
The mpeg4 verification model (WG11/N3908) Section 2.2.2 "Filtering Process"
provides a table of filter taps for downsampling.
The references given are the document MPEG95/0322 and an ftp site
'drop.chips.ibm.com:Tampere/Contrib/m0896.zip'
How can I locate these two sources?
Does anyone have pointers to more reference material on upsampling and
downsampling filters?
Kind regards,
Yossi Shain
