(continued)
• Insertion Sync Byte Control
Allows use of a sync byte from card receiver back to sending source to
synchronize communication between card receive and sending source as
follows:
• Disabled: No special synchronization.
• Field Number at SOF: The card sends a single byte telling sending
source when start of field 1 or field 2 is occurring.
• Ack on Insertion: Card sends a single byte back to sending source
when data has been inserted.
• Extraction Mode Control
Where data is being extracted from input video, sets the data to be sent
as follows:
• Payload Only: Sends payload only (for example, for closed
captioning this would be only the ASCII character string
representing the CC content).
• Full Anc Data Packet: Sends the entire packet, including payload,
DID, SDID, and any handling or marking characters.
• Extraction Flow Control
Allows communication between card transmit and receiving destinations
to regulate data receive as follows:
• No Flow Control: Data is transmitted without buffering or checking
to see if data is being transmitted faster than it can be received.
• XON / XOFF: The card UART Rx will acknowledge from the
receiving system whether it can or cannot accept data at current bit
rate.
• Hold Break: Card, if receiving notification from the receiving
system that it is close to not being able to accept new data, tells the
card to hold. Card releases this hold when the receiving system
removes the break command, indicating destination is now ready
again to accept new data.
• Bit Rate/ Parity Gen Control
For both Rx and Tx, sets UART for bit rate and parity as follows:
• Bit Rate: Sets Tx/Rx bit rate from 1 of 5 speeds ranging from 9600
to 230400 Baud.
• Parity: Sets card Rx to expect odd or even parity from incoming
data, and sets card Tx to generate a parity bit to satisfy selected
parity. Where parity is set, incoming data not conforming to parity
selection is rejected.
