Down conversion is a widespread functionality required in the migration from SDTV to HDTV infrastructures. To ensure a smooth transition LYNX Technik™ provides a variety of solutions including a broadcast quality HD down converter and de-embedder which provides SDTV audio and video outputs in both analog and digital formats.
Multi format operation and flexibility allows the module to be used in a variety of functional applications. With a SDTV input the module functions as a D/A converter, de-embedder and digital distribution amplifier. With a HDTV input the module will provide broadcast quality down converted video outputs in both analog (composite) and digital (SDI) formats with analog and digital (AES) audio outputs. Automatic video format and video standard detection allows the module to detect and re configure itself for the connected input format, perfect for today’s multi-format environments.
Down conversion is full broadcast quality with a choice of output formats of either 16:9 Letterbox, 4:3 Stretch to Fill or 4:3 Center Cut. Built in 709>601 color space conversion ensures legal color reproduction in SDTV and adjustable horizontal aperture correction is provided to add (or remove) sharpness from the converted outputs.
All audio (8xAES) is de-embedded from each input, delayed 1 frame to compensate for the video processing delay and then re-embedded back into the down converted digital outputs. Two digital AES outputs plus two stereo pair analog audio outputs are provided which can be taken from any of the 8 internal de-embedded audio streams.
Local control is provided via the matrix display and user menu system and full remote control is possible when using a LYNX control system option.
