Hi All,
Just wanted to give you two bits of information on some things I saw in the testcards (and I promise to post some of mine soon!)
Circles in cards are used to help identify the correct aspect ratio, and those where the circle appears to rotate are used for lip sync purposes, when the leading edge of the moving circle reaches TDC (top-dead-centre) there should be a either a short 1KHz tone, or a break in a continuous 1KHz tone. Sometimes its accompanied by crosshairs flashing in the centre of each quadrant of the picture. Sometimes the break in tone only occurs on either the left or right channel to ensure the correct channels are mapped in the encoder and decoder.
"FAC-LINE" is an abriviation for Facility Line, a BT provided circuit in the UK to push, in this case, video over the "Telco Network" (IIRC Facility Line for video is ASI over ATM). So the card you are seeing that says that, is almost certainly an occasional coming in to a teleport over a BT Facility line for uplink, rather than a "traditional" OB where the uplink is on the truck.
Thanks,
James.
