Picture in Picture, Embedding External Video
RevelDigital provides a simple means to achieve this functionality without breaking the bank. The only requirement is an Android based PC with HDMI input. Compatible devices are available through us, so just contact us for more information. Enabling live TV in your digital signage template is as easy as adding a TV zone and selecting HDMI as the input type. Most any HDMI source will work including output from DVD players, Cable/Satellite boxes, CCTV, etc.
