We just had our best webcast to date using Wirecast and YouTube Live. The name & calling of each speaker faded in and out near the beginning and end of each talk; the chorister had a webcam dedicated for her with the words to the hymns showing on the lower third of the screen; the Single Adult choir had both a wide angle shot and a bit of close-up panning; all done as discretely as we could with consumer video cameras mounted on tripods.
To keep in the spirit of the thread's subject, I've attached a PDF of our setup. The PDF has 2 pages, the first would be a typical setup if we were to use the VidiU encoder, and the second page is what we used for this past conference with Wirecast. The VCR is used as a crutch until we can get the A/V feeds from the satellite cabinet working properly. The "HDMI to SD box" converts the 1080i from the main video camera to 480i anamorphic (squished), then injected into the stake center's video distribution system via the RCA jack in the back of the chapel. The cultural hall projector and cry-room TV (not shown) are adjusted so the image is shown in the (un-squished) 16:9 format. It obviously doesn't have 1080i quality, but it's really not too bad.
Unfortunately, none of our cabling is hard-wired into the building, so they all had to be laid out in advance and taped down. This requires a bit of work and our stake president asked if we could permanently install some (or all) of it.
This brings me to my question. If we got permission from our FM group to run some cables through the walls and overhead (yes, they would be plenum rated and installed according to local building codes), it would make sense to make them as obsolete-proof as possible, without breaking the bank. For video, SDI is a proven way to have long A/V cable runs without any degradation, but the cost of the converters to & from SDI are quite pricey.
Has anyone looked into the HDBaseT
standard for our buildings? It uses CAT6a cables to transmit uncompressed ultra-HD 4K video up to 100M (328'). 1080p can be delivered using CAT5e cables. At the same time, it can also deliver 100Mb Ethernet functionality, Power over HDBaseT (PoH) up to 100W, and control signals emulating RS232/USB, and IR. Sets of HDBaseT Tx/Rx boxes for 1080p are selling on Amazon in the sub $50 range.
I wish I knew what standard the church is using for new stake centers. I would much rather follow their lead rather than come up with a totally different solution.
