Page 16: Rgb Video Level Calibration
7700 MultiFrame Manual 7730ADC Component A to D RGB VIDEO LEVEL CALIBRATION Calibrating the DC (black) level and gain (video level) of all 3 components can be a challenge when inputting RGB video. When converting RGB to YCbCr, a change in any one of the input components will have an effect in all three of the output components.
Page 17: Audio Buffer Management (+S Option Only)
7700 MultiFrame Manual 7730ADC Component A to D AUDIO BUFFER MANAGEMENT (+S OPTION ONLY) The audio is delayed, through a large memory buffer, by the same time value as experienced by the video through the video frame synchronizer. This is done to maintain a consistent video/audio relationship. Unfortunately, when the video frame buffer drops or repeats frames of video, we can not do the same with the audio.
Page 18: Audio Levels, Headroom, Clipping And The Bar Graphs (-A4 And -Aes)
7700 MultiFrame Manual 7730ADC Component A to D AUDIO LEVELS, HEADROOM, CLIPPING AND THE BAR GRAPHS (-A4 and –AES) This section contains notes to understand how the 7730ADC-A4 relates analog audio levels, digital audio levels, and the displayed bar graph levels. Before you can calibrate the audio analog to digital converter, you must know a couple of system issues specific to your application.
Page 19: Audio Alarm Calibration Procedure (-A4 And -Aes)
7700 MultiFrame Manual 7730ADC Component A to D AUDIO ALARM CALIBRATION PROCEDURE (-A4 and –AES) This section contains a detailed description on setting the various audio warning/error detection parameters. Some of the audio alarm detection algorithms are dependent on the state of other audio alarm detectors. For instance, the mono detection algorithm will not use periods of silence as determined by the silence detection.
Page 20: Calibrate Audio Mono Detection
7700 MultiFrame Manual 7730ADC Component A to D 8.3. CALIBRATE AUDIO MONO DETECTION 1. Supply the card with a stereo signal that originated from mono material and that has a large amount of un-correlated noise added to each channel. This will allow you to set the Mono Threshold to a value that will detect the mono condition in the presence of noise.
