| =====Dirty Little Box=====
| |
| | |
| Dirty, in this case, because it's not very sophisticated. This will convert a 50Hz, interlaced RGB video signal (like the output of a Comodore / Acorn / BBC computer) to a composite video signal. It doesn't do any resolution changing or frame rate conversion, so if your input video isn't at the right rate (and most PC VGA cards won't do the right rate) then the output will go to pieces. As a result this isn't the most useful piece of kit in the station.

| =====VGA to Composite Dongle=====
| |
| ([[User:Malcolm.chambers|Malcolm.chambers]] 03:31, 2 January 2010 (UTC)I don't think I've ever seen this)
| |
| | |
| A rather nasty widget that converts a VGA output from a PC (at any sensible low resolution) to composite and S-video outputs. It's powered from a USB plug (to get 5V), which can if necessary be put in another PC's USB port. It should be noted that as there is no USB data connection, the PC doesn't know that any power is being drawn from the port.

| | |
| =====S-Vid switcher=====
| |
| | |
| * 4-to-1 or 1-to-4 passive switcher(although it can also be used on composite with the relevant adaptors).
| |
| * No syncing, and no framestore.
| |
| * Not clear whether the inputs are terminated when not selected or not.
| |
| | |
| =====S-Vid to Composite exchange=====
| |
| | |
| * Composite into S-video.
| |
| * S-video into composite.
| |
| * Active.
| |
| * Avoids the signal loss and resolution loss by actually extracting the relevant signals and sending them down the required cores, and actively combining the s-video signals to the composite output.
| |
| * One channel one way, 1 channel the other.
| |
| | |
| =====S-Vid DA=====
| |
| | |
| * Splits an S-video input into three identical outputs.
| |
| * Also provides gain and HF boost controls for the chroma channel, to correct for colour loss on long cables.
| |
| * Can be used on composite video through the S-video luma channel as a 3-ouput DA (chroma channel is a bit oddly behaved).
| |
| | |
| =====VT C-E switch=====
| |
| | |
| * A metal box
| |
| * Three BNC connectors and a switch in it.
| |
| *Shove two sources in, and the switch chooses what come out.
| |
| *Also supposed to do appropriate termination for unused source.
| |
| *C-E switch? why? - originally used to swap between VTC (Umatic) and VTE (VHS) due to a shortage of mux inputs.
