Video Output
These fields determine how the card should process the incoming SDI
video data. These fields are set by the user.
Format
Indicates how the card should format the video data prior to
transferring it into host system memory.
YCrCb - 20 bit
Use the 20 bit YCrCb 4:2:2 data received from the SDI
receiver as is.
YCrCb - 16 bit
Use the 20 bit YCrCb 4:2:2 data received from the SDI
receiver but truncate the 4 LSBs to form 16 bit data.
RGB - 24 bit
Use the 20 bit YCrCb 4:2:2 data received from the SDI
receiver, translate it to 30 bit YCrCb 4:4:4 data using a
chroma resampler function, then generate 30 bit RGB data
using a color space converter function and finally truncate
the 2 LSBs from each component to form 24 bit RGB data.
Transfer as
Indicates how the card should transfer the video data into host
system memory when the mode is ‘interlaced’. Note that when the
mode is ‘progressive’ then the ‘frames’ option is automatically
selected.
Frames
Interlaced:
Transfer as a complete frame consisting of
an odd field followed by an even field.
Progressive: Transfer as a complete frame with odd and
even fields interlaced ( i.e. as received from
the camera ).
Fields
Transfer each field individually.
Audio Input
These fields describe the attributes of the currently connected SDI audio
source. The fields are automatically populated by the application program.
Present
Indicates that the received signal contains embedded audio data.
Audio Output
These fields determine how the card should process the incoming SDI
audio data. These fields are set by the user.
Enable Preview
Instructs the card to process and play, through the PC’s speakers,
the received audio data.
Format
Indicates how the card should format the audio data prior to
transferring it into host system memory.
