I have a mobile stage. FOH is usually about a 75' run from the stage. Have a cat5e from FOH to stage running a small Dante setup. 16 Channels to a QL1. Have two screens that I want to display video content on each side of the stage. Can I stream H-264 along with the Dante? Mostly SD 4:3 but may want to run HD at some point.
Any thoughts? I am trying to get away from running SDI cable and multiple converters (HDMI-SDI-HDMI)
I'll likely come down to bandwidth and latency. How many channels of audio at what bitrate are used by Dante, and what bitrate is the SD video you're using (H.264 is a compressed video format, so the bitrate is adjustable on most encoders). Note while that Cat5e can handle 1000 Mbps, that is theoretical in many cases and it's worth testing your cables and switches to verify their actual field performance.
Also note that H.264 takes much more time to encode than decode, so if you have any live video sources (i.e. IMAG) it'll likely show a large amount of latency and not work very well. Uncompressed video formats (e.g. SDI and HDMI) are typically better suited for live video because of this, in addition to being higher quality.
