Page 5: Introduction
The UP-DOWN-VF is a range of four up-down converters for use with ‘Vision’ rack frames from Crystal Vision 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 6: Block Diagram
UP-DOWN-VF is a space-saving 96mm x 325mm module which fits in the standard ‘Vision’ frames from Crystal Vision, with the inputs and outputs accessed by using either the VR01, VR03 or VR14 rear modules. Control is by the ‘Vision’ frame active front panel, remote ‘VisionPanel’... -

Crystal Vision Introduction initially delayed by up to three frames under user control and then further delayed to match the video delays through the synchroniser and to maintain correct alignment of the guardband. After embedding, the combined video and audio stream can be delayed by up to 40ms in 10ns increments. -

Page 17: Control And Status Monitoring
UP-DOWN-ATXS-VF Status page 5.2 Control Descriptions Crystal Vision cards use an XML file to create a control database that is common to all controllers. Although the description of controls used in this manual is based on VisionWeb GUI screengrabs, the menu tree for VisionPanel and Vision frame front panel operation is the same, although the appearance and labelling of some controls may vary according to the available space. -
Page 18: Status Menu
Crystal Vision Control and Status monitoring VisionWeb GUI controls are accessed by tabs at the bottom of the page: Status, Video, Audio, Data insert and Presets, default, alarms. These tabs, when selected, offer menus containing several controls. Some controls are simulated LEDs that are used to show status, others are check boxes, buttons or sliders which change various UP-DOWN-VF settings. -
