ASVC010 - BALBOX Analogue Component to Serial Video Converter.

The ASVC010 provides conversion of analogue component video signals to serial digital video at 270Mb/s. The user may select the analogue input format to be YPbPr or GBR. The user may also select Syncs to be taken from the Y/G input or a separate composite sync input. Analogue to digital conversion is at 10-bits and the analogue processing and filtering has been matched to preserve the analogue component quality. Although primarily aimed at compact or temporary installations, the unit is suitable for studio and outside broadcast applications. Four 270Mb/s serial digital outputs are provided, removing the need for separate SDI distribution amplifiers in many instances. The user may select to pass or blank VITS present on the analogue input, may select to blank the serial video outputs and may select an internally generated digital colour bar signal for test purposes. The unit has an integral mains power supply.
