Hi Tom,
I just found your posting of the ITU-R BT.1729 colour bar test pattern.
This is great!
Does this fully implement the ITU-R BT.1729 colour bar test pattern?
** BOUNCING BALL: I couldn't find anything in the standard that
mentions a bouncing ball, but I like the feature and one could argue
that this might catch some problems missed without it.
** ZONE 12 MOVING BAR: Page 6 of the standard states that "Zone 12
contains a bar which moves horizontally from
left to right and then starts again from the left. This is used for
checking audio-video synchronization and to establish that the channel
is active. The bar travels horizontally across its zone in 1 s. The
audio sync signal is given when the bar passes the centreline." There is
more description to the zone 12 in the standard, but the above quote is
sufficient to say that I don't see anything moving in zone 12 of your
application.
Do you have plans to fix the zone 12?
I am definitely looking for something I can use to test monitors for
CISPR32 using the ITU-R BT.1729 colour bar test pattern.
For all, the ITU-R BT.1729 standard is available online for free at:

Thanks.

Hello,
We used to use scrolling-Hs test pattern for CISPR 22 and ANSI C63.4,
but CISPR 32 requires ITU-R BT.1729 colour bar with small moving element
for computer displays and similar devices.
Now, I made web pages which will display the test pattern on web browsers.
