CSI-DEC Serial Digital 용 Control Signal 디코더 입력 : 1 x SDI 출력 : 2 x SDI  Control Signal Decoder  GPI outputs  LCD Display  RS232 / 422 Microvideo are able to offer systems for sending and decoding basic control data within a digital video signal. These systems utilise the Vertical Blanking Interval (VBI) within the video signal. Data is decoded by a digital PLL, and while the encoding scheme allows for some deterioration of signal, it is assumed that the link between encoder and decoder will be of broadcast quality. It is also assumed that any video compression applied to the signal after encoding will pass the VBI lines through as video. The deoder has a realtime clock and any changes to the data are logged and also sent to the serial port. This data sheet describes the Control Signal Decoder. The encoder has part number INS-CSI, the specifications of this are available on a seperate data sheet. Specifications Video Input: SDV(270Mb/s) as per SMPTE259M Video Output: 2 x SDV(270Mb/s) - Program and AUX n.b: Program and AUX outputs are the same, but a power-fail bypass relay connects SDV In to only the Program output when no power is applied. Control Data Outputs: Four GPI outputs (open collector, active on connection to ground) on 9 way D-type. Front Panel Controls: GPI output enable/disable (when disabled GPI outputs are not driven) Test mode (Allows GPI outputs to be set from front panel) Status (shows whether signal is valid, invalid or not present) Physical: 1U rack mounting frame with integral PSU.
