Overview

The 3G+4+ Tiler has a built-in command to allow a single source to be displayed on top of a primary source and specify the level of opacity/transparency of the video pop-up. This allows the effect of "seeing through" one source to another, giving an enhanced picture-on-picture viewing experience.

 

The size and position of the pop-up source are configurable, as well as the level of opacity or transparency of the pop-up.

 

Requirements

  1. 3G+4+ Tiler running version firmware A6.5.5
  2. Download and apply the patch file attached to this Knowledge Base aerticle as a firmware update to the Transmitter in the 3G+4+ Tiler
    (A6.5.5 3G+4+ TX - PoP Patch.bin)

Setup

  1. Switch RX1 of the Tiler to the source you want as the background
  2. Switch RX2 of the Tiler to the source you wish to appear as the popup

 

Command

_4in1_pop.sh hpos:A vpos:B width:C height:D (opacity:E || transparency:E)

 

Where:

A = a number from 0-1920

The horizontal position of the popup (offset from the left) relative to a 1920x1080 canvas

B = a number from 0-1080

The vertical position of the popup (offset from the top) relative to a 1920x1080 canvas

C = a number from 0-1920

The width of the popup in pixels relative to a 1920x1080 canvas

Not to exceed the total width (1920) less the horizontal position

D = a number from 0-1080

The height of the popup in pixels relative to a 1920x1080 canvas

Not to exceed the total height (1080) less the vertical position

E = a number from 0-100

For opacity, the relative opacity of the popup in percent

Where 100 is completely opaque and 0 is completely transparent

For transparency, the relative transparency of the popup in percent

Where 100 is completely transparent and 0 is completely opaque

 

Examples

Set the Popup to be 640 pixels wide by 320 pixels high, offset 100 pixels from the left and 100 pixels from the top, with 75% opacity: 

_4in1_pop.sh hpos:100 vpos:100 width:640 height:320 opacity:75

Result:

Set the Popup to be 1920 pixels wide by 1080 pixels high, offset 0 pixels from the left and 0 pixels from the top, with 75% transparency:

_4in1_pop.sh hpos:0 vpos:0 width:1920 height:1080 transparency:75

Result:
