This chapter describes the optional HDMI input card, for other input or output boards, please see the introductory chapter.

There is one HDMI 2.0 card available with two inputs (HDMI Type A).

The card allows to input HDMI signals to be used within the Pandoras Box render engine.

Supported Video Formats

The HDMI 2.0 capture card supports on both inputs simultaneously any HDMI format, including 4K @ 60Hz with a color depth of 24bit/px.

Note that HDMI is backward compatible with DVI (single-link DVI-D, but not DVI-A). It is possible to use DVI to HDMI adapters and keeping the video quality as no signal conversion is required .

The following table lists the maximum framerate for some standard 16:9 video formats. Please note that HDCP-protected signals can not be processed! Audio formats are also not supported.

Frame rates from 23.98Hz to 120Hz depending on formats

Driver

The card drivers are preinstalled on your Server or Player hardware. All drivers can be found locally under C:\system and in the Download-Center where you can also check for updates. The driver installer searches automatically for existing cards and installs the appropriate version.

Working with Video Inputs in Pandoras Box

Video Inputs in Pandoras Box are managed by the Pandoras Box Master, that is responsible for the entire show control. Only if you use the Master in stand-alone mode, you would connect the video device to the Master's input board. In case you work in a Master-Client-setup and you like to use the stream on a Client, the Client must be equipped with an input board (not the Master). In other words, the physical signal input happens on the same machine which should render and output the image. The video stream only "exists" on the Client, it is not distributed to the Master nor to another Client. If you like to display the stream on several Clients, all of them must be connected to the video source.

Follow this step-by-step description after having connected the video source to the input card.

Master-Client-setup:
- start the Master and Client computer and make sure that Pandoras Box runs on both in the correct Master or Client mode and the same revision
- then go to the Master, Asset tab > your Client > folder "Live Inputs"
- drag the according card into the Project tab; this initializes the card
(- it is not necessary to configure the card, as known from the SDI or DVI card)
- assign the live input to a layer in the Device Tree the same way as using common image or video files

It is also possible to record the incoming signal. However, the Client computer must then be started in stand-alone mode, that is with the Pandoras Box Master software. Please see the chapter " Video Recording" for more information.

Stand-alone setup:
- start the Master computer and Pandoras Box in Master mode
- then go to the Master, Asset tab > your Client > folder "Live Inputs"
- drag the according card into the Project tab; this initializes the card
(- it is not necessary to configure the card, as known from the SDI or DVI card)
- assign the live input to a layer in the Device Tree the same way as using common image or video files
