NeTV local UI is entirely rendered by Webkit browser, running in a chromeless/fullscreen fashion. The UI is written in JavaScript & HTML. Hardware integration is supported by submitting POST/GET request to http://localhost/bridge. See NeTV_web_services.

The starting point for playing with the UI is to edit files found in /usr/share/netserver/docroot This is translated to http://localhost

The overlay effect is done using chroma key compositing.
Any color that is (240,0,240 or #F000F0) will take on the color of the background video stream.

The browser executable is located at /usr/bin/NeTVBrowser To start/stop/restart the browser, use a helper script

/etc/init.d/chumby-netvbrowser start/stop/restart



To point the browser at a different URL
Note that, however, a keep-alive timer will kick in within 1 minute and switch it back to http://localhost/

NeTVBrowser -qws SetUrl http://www.yoururl.com

The correct way to keep a page on screen is to use the browser's multi-tab feature

NeTVBrowser -qws Tab 1 http://www.yoururl.com
NeTVBrowser -qws Tab 1 Hide

Where '1' is the index of the tab. Maximum 10 tabs are supported (index 9).
Tab 0 is reserved for NeTV UI.
A keep-alive timer is responsible to keep it pointing to http://localhost at 1 minute interval.



To call or inject JavaScript function from SSH console (remember to escape special characters):

NeTVBrowser -qws JavaScript "console.log('hello console');"
NeTVBrowser -qws JavaScript "my_function();  function my_function() { console.log('hello console'); }"



Night mode (Tab 0 only)

NeTVBrowser -qws InvertColor on
NeTVBrowser -qws InvertColor off



Make the browser fullscreen / NOT fullscreen

NeTVBrowser -qws Fullscreen
//NeTVBrowser -qws SetBox xx yy width height
NeTVBrowser -qws SetBox 100 100 400 300
