Hi,
        What is the difference  between CIF target and SIF target? What is the related applications 
for them? If I get the decoded frames with 25fps, but the TV system is NTSC, 30fps, how to convert
the video from 25fps to 30fps? Or how to convert between 25fps system and 30fps system?
Regards,
Jefferson

Dear Hans Juergen,
Thanks much for the tip!
Please note that we implemented this feature some months ago:
http://www.m4if.org/index_search.php
This link can always be found under 'Qiuck Links' in the 
right-hand column of the website.
Kind Regards,
Rob

The trouble with that link is that it uses the old domain lists.m4if.org  
instead of lists.mpegif.org, so it doesn't work, at least not for me  
when I tested it today.

Yes, I found it by chance today when visiting the homepage again, but in  
my opinion a search function should be placed either on the left side  
with the main navigation links or on the bottom in the navigation bar,  
because it's too important to be overlooked.
By the way, this method (using site: plus domain in Google) is also  
useful for other related websites without an own search engine, e.g.:
the MPEG homepage: site:mpeg.telecomitalialab.com (offline at the  
moment)
or the MPEG Audio Subgroup: site:www.tnt.uni-hannover.de
ZZee ya, Hans-J|rgen

  Hi Harish,
    MPEG-4 Reference Software (both Microsoft's and Momosys's) for "Advanced Simple Profile" implements "quarter-pel motion compensation".
  Best Regards,
  Parag.

Thanks Hans-Juergen,
the site name has been corected in the archive search.
Note that the MPEG home page has moved to www.chiariglione.org/mpeg (also
updated on MPEGIF's home page)
Best,
Rob

Levels in AAC have been defined in terms of PCU and RCU.
PCU is defined in terms of MOPS. But what do you consider as an
operation?
Also RCU is defined in KWords. What is the length of an word in this
case?
Thanking you,
Apala Guha

Hi,
	I built some tools for the MP4/3GPP files. You can download them from the
	http://members.xoom.it/catrambone/Streaming/CatraStreamingPlatform.htm
	site.
	See the "Download -> MP4 Tools" section.
	Let me know if you have problems to run it.

Subject: [Mp4-tech] Hinting of Mpeg-4 file
Hi all,
Does any one know if I can use QuickTime Pro API to do
hinting of an encoded Mpeg-4 file, such that I can
stream the file with DSS? 
If so, could you tell me how to do it? If not, then is
there anyway I can hint a Mpeg-4 file instead of using QuickTime Export function, as I need to embedded the function into my own program? Actually, I've tried MP4Box to hint the mp4 file, though the resulting file can be streamed by DSS, the video is freezed at the first frame. 
Plz Help
Derek
