Zoran Datasheets?

I'm trying to find a datasheet and programming manual for a Zoran
ZR36966

Zoran do not put their datasheets on the web, and none of the usual
suspects seems to have them either.

An email to 'general support information' yielded nothing. An email to
the 'company contact' listed in their press releases yielded a curt
'who are you and why do you want it?' But I obviously failed with my
answer as the contact went silent. :-(

A clue may be found in the footnote of the 'product brief's :-

"Copyright 2005 Zoran Corporation's Vaddis 888 incorporates
Macrovision, Dolby and CSS Technologies. To obtain Vaddis 888, the
recipient must have the appropriate licenses with these entities. Due
to the
programmability of the Vaddis 888, other licenses may be required."

Well, given I've already got one at home, and you probably have too,
I've already obtained one, I just want to know a bit more about it ;-)

Any help would be appreciated.


Re: Zoran Datasheets?


You got it as part of DVD player, which is different.

They are right, though. To get the complete info, you most likely have to
sign an NDA with Zoran and other parties. I am afraid, Zoran is the only one
who can help you.

Try telling them you are considering using it in a new design.

other parties.

I'd be happy to sign an NDA, but it never even got that far.

Unless you are a company, e.q. "legal entity", they will not talk to you.

It is all down to how good you can b@@@@t them. Seriously, what is the point
for them do deal with you? Absolutely nothing. Unless they can see a case
for more sales, they will not.

I look at it in a different way. What is the point of *not* releasing
information about how your chips work? If Zoran, or any other chip
manufacturer, wants maximum market penetration, surely they should
welcome the thousands of programmers and enthusiasts who would develop
applications for their chips at no cost to Zoran. For example, if
Zoran were to release the programming details for their chips, I'm
sure that the entire Linux community would be interested. As it is
now, the Chinese manufacturers take a reference design, layout a PCB,
and tick the checkboxes for the various firmware options. Zoran does
virtually all the hard work.

Yes,

But if one  big DVD manufacturer produces a million DVD players, Zoran only
have to provide technical support to a handfull of engineers. The support
can be deep focused.

Rather than,  support a 1000 engineers  for very few sales per engineer
support.

Sure, one or two designs may take off,  but if Zoran may have already
targeted them  (with proper marketing).

It's the ratio of support costs / number of chips sold.

Anyone with a brain will put all the info on the internet so it's
available to everyone. Siemens is a good example, you can find
everything ever published by them on the net, and it's free to us. If a
company won't give you support you don't buy their product, it doesn't
get much simpler than that.

Hey all, my $0.02 worth from a little experience.

The Zoran and other chips that contain macrovision and CSS hardware
modules and are prevented from releasing technical details under the
license terms for incorporating the aforementioned technologies.

In order for them to release the full data, you need to get a
macrovision license and a CSS license from the relevant licensing
bodies. Then you can show these to Zoran and they can release the
datasheet that contains confidential (proprietary) data about these
technologies.

Neither of these licenses are cheap or easy to get. Unless you're
planning on making lots of units (10,000+) with these chips, the cost of
obtaining the licenses is prohibitive.

Zoran have their hands tied on this issue by legal (BS) stuff.

Then why not just withhold the CSS and Macrovision stuff and release
the rest? In any case, what prevents PC motherboard chipset
manufacturers and graphics chipset manufacturers from releasing their
info?

Re: Zoran Datasheets?


The only pleasant experience I had was with Philips.
Needed to use one of their USB host contrroller IC in a design. To get the
info, all I needed to do is to submit an application on their web site. Next
day I received acecss to all the info including sample drivers and source
code application software. Fair enough, they have to protect their IP, but
they have an efficient system to release stuff.

Rudolf
P.S. Many chip manufacturers will not release the info in fear of
competition. Try to get any info on WiFi chip sets, like PRISM.

Tell me about it! I wish, Zoran were the only ones.

I am an engineer and this is a constant pain in the a@@@.
Sometimes it is difficult, if not impossible to get information for the
commercial projects. I can understand things like specialised micros, like
Zoran, but currently I am trying to get manuals (hell, even datasheets) for
integrated network switches from Marvell and for SLIC chips from Legerity.
And those are the things that we plan to use in the commercial products
(thouthands of chips).
