  • Page 8: Basic Functionality

    Inputs and Outputs Figure 1–1 illustrates the basic inputs and outputs of the HDCC-200A. In the event of a power failure, or when the system is powered down, the bypass relays engage and the outputs on O/P 1 and O/P 2 are identical to the input signals on I/P 1 and I/P 2 respectively.

    I/P 1 and a clean video stream would come in on I/P 2. In this scenario, the HDCC-200A would copy the closed caption text data coming in on I/P 1 and embed it into the video stream of I/P 2.

  • Page 13: Using The Card

    Us i n g the C a rd Using the Card Using the HDCC-200A card amounts to little more than setting the switches, attaching the I/O cables, and connecting a PC through either an Ethernet or a serial port to encode or analyze. (But a PC connection is not needed for bridging.)

  • Page 16: Encoding And Decoding

    Engineering Registers on page 17 for more information. Encoding and Decoding Because the HDCC-200A is a true, dual-channel card, it can simultaneously encode one input and decode the other. I m p o rt a n t : You cannot decode the captions you are currently encoding. To decode, the captions must already be on the incoming data stream.

    Typically the GPI data is encoded on Line 9 of the HD-SDI signal and on line 19 of the SD-SDI signal. However, the HDCC-200A is flexible enough to allow you to assign the lines on which you want the GPI data.

    The GP outputs are optically isolated and “open collector” so the user must provide the appropriate pull-up resistor for each GP output. See Figure 3–3 below. The HDCC-200A provides four GP outputs. (See Connector Pin Assignments on page 57 in Chapter 4 for connectivity.)

  • Page 51: Alternate Uses

    In addition to the standard functionality, the GP inputs can be re- assigned to perform specific pre-defined tasks. W A R NI N G! EXERCISE EXTREME CAUTION when modifying register values. Improper configuration of the registers can cause the HDCC-200A to behave in unexpected ways. These functions include: •...
