Introduction
flagging up faulty signals, especially in multi-channel applications. Amongst the status
indications available are - video not present, video frozen, video black and both audio
not present and audio silent on all four groups. The
Q-Down-ATG 3G
will transport
timecode and closed captions with the ability to convert ATC to VITC when down
converting. It is also possible to select the insertion lines adding to Q-Down-ATG
3G’s
flexibility.
The Q-Down 3G range is a space-saving 100mm x 266mm module, with up to 12
boards fitting in a 2U frame alongside the rest of the Crystal Vision Indigo product
range. The inputs and outputs are accessed by using the RM41 and RM57 frame rear
modules, with the RM34 rear module additionally used to access the optional top
board outputs. Control options include VisionWeb web browser control software,
VisionPanel remote control panel, SNMP or an active front panel on the frame. Card
edge control was also available prior to 2018. The Q-Down 3G range is ideal for use
in mixed 3Gb/s, HD and SD environments, or for any areas being converted to HD or
3G.
