Keep the maximum quality of your HD signals

Q-Down123 has been designed for broadcasters who want to keep the maximum quality of their HD signals when down converting and simplify their system design.

Combining the three advantages of outstanding picture quality, short processing delay and competitive pricing makes it Crystal Vision's most popular product.

Q-Down123 can down convert 720p and 1080i at 50Hz and 59.94Hz. The down converter is bypassed when the input and output are the same standard so that the signal is passed without degradation.

Q-Down123 is ideal for use in a mixed High Definition and Standard Definition environment and for any areas being converted to HD.

Flexible analogue and digital output combinations

Q-Down123 offers real flexibility when it comes to configuring the outputs - providing two reclocked loop-throughs of the HD or SD input using the RM34 frame rear module, along with three down converted video outputs.

The three down converted video outputs are individually selectable as mixtures of SD digital and analogue, with the analogue video configured as composite, Y/C, YUV and RGB.

By using an alternative rear module - the RM45 - one of the loop-throughs can be exchanged for a dedicated SDI output, thereby increasing the number of applications.

Unique level of image quality in its price range

Using Crystal Vision's proprietary processing, Q-Down123 provides a unique level of image quality in its price range - avoiding aliasing while retaining picture sharpness.

The sophisticated two dimensional filtering gives broadcast results without the complication of looking at multiple fields or movement detection - resulting in reliable, artefact-free conversion.

There's the choice of four alternative filter characteristics - sharpest, sharp, softest and soft - for those who want to optimise the performance for their material.

Easy to keep everything in sync

With Q-Down123 there is no need to compensate audio or other signals for the video delay. The short processing delay of just 16 SD lines (or 52 lines with Letterbox conversions) keeps everything in sync, making your system design much simpler - and makes it easy to detect real lip sync errors when you're monitoring the video and listening to separate audio.

Match other delays in your system

For those that want to match other equipment delays in the system there are three fixed video delay settings: ‘minimum’ (16 or 52 SD lines processing delay, depending on the conversion), ‘fixed’ (52 SD lines) and ‘frame’.

The ‘fixed’ 52 lines delay allows the aspect ratio to be changed live on air without any picture disturbance, while the ‘frame’ of delay can be used to match a variety of equipment or alternatively to connect with equipment that has no delay.

HD to SD aspect ratio conversion

Q-Down123 includes the ability to deal with any HD to SD aspect ratio conversion requirements. You can select a 16:9 Anamorphic output for 16:9 SD systems and either a 16:9 to 4:3 Letterbox or 16:9 to 4:3 Full Screen with centre cut for 4:3 SD systems.

Save rack space

Integration with the full Crystal Vision interface, keying and picture storage range is intentionally easy, with this space-saving 100mm x 266mm module housed alongside any other product in the standard frames - available in 4U, 2U, 1U and desk top box sizes - and with up to 12 boards fitting in 2U.

Choose your control

The flexible control options include board edge switches, an active front panel on the frame, a remote control panel, SNMP and the Statesman PC software.
