Page 6: Introduction
Crystal Vision Introduction 1 Introduction The Up-Down 3G is a range of nine up-down converters that allow flexible up, down and cross conversions between 3Gb/s, HD and SD sources, provide an output picture of exceptional quality and include special features to allow studios to easily operate in HD and SD at the same time. - Page 7 Crystal Vision Introduction Up-Down 3G is a space-saving 100mm x 266mm module which fits in the standard Crystal Vision frames, with the inputs and outputs accessed by using either the RM41 or RM57 frame rear modules. Control options include an active front panel on the frame, a remote control panel, SNMP and the VisionWeb PC software.

Page 22: Audio Delays
Crystal Vision Delays Note: The 'frames' used for describing delays are Dolby E frames. For interlaced video, a Dolby E frame is the same length as a video frame. For the relevant progressive video standards, a Dolby E frame is the same length as two video frames. -
Page 23: Tad Versus Slew Rate
Crystal Vision Delays The faster the TAD speed, the faster the audio delay will match the video delay, but at the expense of musical pitch. Since the TAD speed can be audible as a pitch change, the response time needs to be chosen with care. - Page 24 Crystal Vision Delays The user delay determines whether a stereo channel passes through the "user" audio delay, or bypasses it with minimum delay. The "user" delay for Dolby E is (7), for other audio it is (4). The Resample Enable control affects how the audio data is manipulated to change the PCM delays.

Crystal Vision Appendix 1 Resamplers The Resample Enable control affects how the audio data is manipulated to change the PCM delays. On resampled channels (resample enabled) the audio will be continuously resampled allowing seamless changes in audio delay. On non-resampled channels (resample not enabled) samples will be passed unchanged through the signal path: if the delay has to change, single audio samples will be dropped or repeated as required. -
