video/audio output
the video and audio inputs can be monitored via the connectors on the output breakout cable. the cable includes connectors for:
video outputs
1 composite (bnc)
2 s-video (mini-din)
audio outputs
·unbalanced audio (two rca connectors).
audio processing
1 auto sample rate selection for analog inputs (32 khz/44.1 khz/48 khz)
2 audio sample rate down conversion based on application requirements
3 audio sample rate up conversion based on application requirements
4 gain and attenuation can be controlled in hardware for analog inputs. for digital inputs a software gain or attenuation can be applied.
hardware video processing
一、dv decoding in hardware produces a decompressed video and uncompressed audio stream that can be captured.
二、scaling can be applied in hardware to any video source before capture.
三、color space conversion can be applied in hardware before video is captured to the host. supported color formats are:
1 rgb (32/24/16/15)
2 yuv (4:2:2 packed or planar yvu9/yuv12)
3 grayscale (y)
四、cropping can be applied in hardware to any video source before capture.
五、brightness/contrast/saturation/hue adjustments can be applied to the analog inputs prior to capture (hue not applicable to pal signals). for digital inputs, only the first three can be adjusted. bypass color correction is available for digital inputs that allows for the digital inputs to not have any correction applied. this is the recommended mode for digital inputs.
