Patrick,
Got your email and just left you a voice mail.
I now have another HDP set up at my place with a G90 to test this out and am having the same results at 720P using Comcast.
Sorry if this isn't he place to talk about this, but I would be interested to see if any other CRT users are having these results.
Stopdog, no question DVD scaling either component or SDI in are awesome on the HDP. I don't know why 1080P looks better and my viewing is somewhat limited. Testing at my place really doesn't count because I don't hink that Comcast does as good a job with 1080i as voom or dish.

Chuchuf,

Does this update add film mode to 1080i ?

BTW, your description of the problem seems vaguely familiar to Macrovision artifacts, don't you think?

Cheers,

In case anyone missed the post done by 1st on the block...

Lumagen is happy to announce production release of the VisionDVI, VisionHDP and the VisionPro HDP – with a couple of changes. This release-candidate software is now available, and includes a much nicer “all-in-one†update program that is a Windows application rather than a DOS app.

There are two significant changes in feature release strategy at production-release date from previous postings. We have had a lot of people wanting us to release to production, even though we are not yet done with the HD inverse-telecine or the 10-bit math pipeline. We agree it’s time. So, we have worked hard to complete other aspects of the product and to clean up known bugs. We will still do both the HD inverse-telecine and 10-bit pipeline for both the VisionHDP and the VisionPro HDP, but these will be in later production releases. We are planning to release HD inverse-telecine in January and the 10-bit pipeline in February.

Here are some areas we are placing at highest priority to continue improvement after this release, in approximate priority order:

- HD “passthrough-plus†mode. This is a pass-through (i.e. no scaling) but with calibration features.

- 480i digital input mode (psuedo “HDMI†mode).

- Improved PAL deinterlacing for SD sources.

- HDCP compatibility. Still have a couple of issue here, but have fixed most of them.

- HD inverse telecine

- 10-bit datapath

And of course we will fix bugs as quick as we can when they are reported.

Jim, as you know, I LUV my Lumagen VisionPro HDP and your support. There is no company in the industry that does better tech support and prompt innovation.

Question re the upcoming HD pass through plus mode for those of us with analog CRT projectors? Do I assume correctly that this feature will still convert incoming analog video to digital, and then permit calibration (color, black level, tint, etc.)? Will it then permit size and timing adjustments?
Will it transcode? And assuming its still converts incoming analog video to digital, then what is the advantage of this mode vs just using the regular mode and setting your output to the same as the incoming scan rate, which I do now with my Dwin HD-700 CRT projector?

Or is this an analog pass through?

Thanks.

May i know what exactly the 10-bit pipeline does?

It helps to reduce noise because the calculations are more exact.

Also we had a couple of quick last minute bugfixes so we just reposted our production sw release--the black level adjust was not working correctly in releases 120304 & 121504.

Hi Patrick

Any chance you could just have a quick look at my thread on the official beta forum, here

I've just updated the firmware and have come across a problem, hopefully you can help..

Thanks

Ryan

Edit: Problem solved now that I've used the very latest firmware...

This passthrough-plus mode allows all calibration features, but disables scaling for DVI out and disable vertical scaling (still has analog output oversampling) for analog out. So all normal features such as transcoding analog in to digital out, color of gray, color, hue, color offsets for red and green, black, contrast, etc. will still function.

No sizing adjustments will function since the intent of the mode is to disable scaling.

So, this is not analog-passthrough, but a direct path for digital in, and a direct path for analog in after the A-to-D stage, but with access to all the calibration features if desired.
