NeTV application for digital signage application

[nitrous]

Hi there,

I just spotted the NeTV hardware on the sales site.

If I understand the limited amount of information correctly, I can use this to put a digital sign across the bottom of an HDTV, using HDMI feed from a digital cable box. Is this correct?

Next question is, what software exists that would let me put messages down at the bottom of the screen or do I have to write this application myself?

Is there a webpage with more details available somewhere? It's a bit difficult to decide if this hardware will meet my needs.

Thanks guys,
Doug

Not even some feedback from the designer?
It would be helpful to get a little input from those who actually know.

yes, you are correct, you can put a digital sign across the bottom of the TV screen if you wanted.

The device comes out of the box with a demo app that can absorb messages from twitter feeds, or you can use http POST to send events to the box from a remote or local source that can cause "event" messages to scroll across the screen using the demo framework (see http://www.kosagi.com/w/index.php?title ... b_services). Note that it is a demo framework so you'll probably have to customize it for your specific application.

However, keep in mind that *everything* on NeTV is just a webkit web page. The video is just "magic pink", i.e., chroma key, in your web page art, so if you know javascript and html you can write your own apps.

Thanks Bunnie,

Does the device come with any documentation that might help with ths or is it pretty much DIY?

For example, if I had a java script based ticker application, that put a ticket tape at the bottom of my computer screen, could that be displayed on the HDTV via the NeTV box?

Thanks again for your reply. Given the 90+ views of this post, there might be some interest in this subject.

Hi Doug

Sorry -- I'm terrible about following up on forum posts.

All the docs that exist are at http://kosagi.com/w/index.php?title=NeTV_Main_Page
pay particular attention to
http://kosagi.com/w/index.php?title=NeT ... evelopment

It is pretty much DIY, but the idea was to make it so that it ran a base set of HTML/javascript so that you can dev your apps on your desktop and then point NeTV at it. Make sure you turn off the keepalive timer.

The UI is just a browser, with the only trick being that "magic pink" color (240,0,240 or #F000F0) is replaced with video pixels. So if you set up your CSS to be correct (turn off anti-aliasing so you don't get pink rings around your graphics) you can pretty much just dev your pages on your machine and bounce them over to NeTV.

Thanks Bunnie,

I'm going to try a Java scripted info ticker application to start. Unfortunately, Adafruit doesn't have any in stock right now.

I appreciate your response. "Real life" can have a funny way of getting in the way of things like forum activity!

Take care,
Doug
