2.3 Content source
The viewer is built around a smart phone LCD display having the resolution that
varies depending on the type of LCD panel you ordered.
The choice of a content sources, cancels out devices which are unable to deliver this
the native resolutions that the LCD requires! So check chapter 3.2 for video input
requirements. Computer systems having a more advanced video processing output
(separate video cards or graphic processors) are often automatically able to address
portrait oriented
LCD’s trough the EDID information.
Simple small single board computers, depending on the operating system, require
more knowledge to configure the vertical display.
Be aware that there are a number of professional multimedia players having fixed
output resolutions to select from, they do not match with portrait displays!
Using a single board computer like the Raspberry pi
De Wijs offers a simple solution as content source; the Raspberry pi. The choice for
this device has several reasons:
- affordable and very good available.
- The graphical output can be set to the required LCD configuration of the 3D
viewer up to QHD resolution.
- The General Purpose IO header on this board allows push buttons to control a
slide show or start a video.
- Open source software that can be adapted for your application.
We use Pi-presents that gives a good solution for an interactive slide show
with acceptable performance.
