support - frequently-asked questions

What is the origin of the Eyeheight company name?

When serial digital video signals are displayed using an oscilloscope or waveform monitor, the display shows what is often referred to as an 'eye' pattern. Transmission losses progressively reduce the harmonics in the signal and increase noise. These losses close the "eye" in a vertical direction. Increasing jitter (fluctuating timing errors) close the eye in a horizontal direction . The wider the eye opens, the better the chance of equipment sampling the SDI signal correctly. The 'eye height' is commonly used to make a subjective assessment of the signal integrity, hence the origin of the Eyeheight name.

How long has Eyeheight been active?

Eyeheight was established in 1992. Founded by Martin Moore and Steve Crocker, the company has grown steadily and has built a solid reputation for high quality reliable products. We celebrated our 20th anniversary in September 2012.

Where can I purchase Eyeheight equipment outside of the UK?

Eyeheight has resellers in many countries worldwide.

What is geNETics?

geNETics was the technology name given to the most recent generation of products to be designed and manufactured by Eyeheight. The choice of name alludes to the technologies network operation and modular construction. geNETics is now the family name for Eyeheight infrastructure products.

What is presTX?

presTX is a compact modular presentation mixing and channel branding system based on the Eyeheight geNETics product range. Selecting only the control panels and function cards you actually need for your system ensures value for money. Because it presTX is based on geNETics, it is always expandable to meet future needs.

Television stations are under ever-increasing pressure to make their own identity or channel branding system stand out from the rest. The Eyeheight presTX is designed to achieve a powerful and consistent look using total digital technology and a novel use of networking systems. The channels overall image has to be paramount and simple so that viewers associate this channel branding system with a strong message. The presTX provides this complete channel experience.

presTX has been designed using Eyeheight's innovative Common Hardware Platform, and is built up using the Eyeheight geNETics system. This provides each on-air channel with a cost-effective recognised logo or channel branding system, which uniquely distinguishes this channel from the rest. This system's innovative use of building block technology means that presTX can be for example, a very simple SDI A/B mixer to a full-blown mix, wipe, linear key with DVE, providing a flexible channel branding system together with an associated AES/Embedded Audio Mixer. This is achieved by adding different modules to suit the users requirements, and makes the whole system very flexible, being tailored to very specific individual clients' requirements. The system is robust and cost-effective and is equally at home in a broadcast, multi-channel, or post-production application.

presTX can provide A/B SDI video switching coupled with an associated A/B group AES/EBU/Embedded Audio Mixer. These can be locked together or manually cut away for separate operation, all under automation control. The program A/B feeds are fed from an external router, and can perform both horizontal/vertical mixes, wipes etc. as well as cuts and fades with totally adjustable fade rate and wipe softeners. Previewing of the next switcher position is provided for rapid monitoring. Associated with this A/B switcher is a powerful AES/EBU Digital Audio and Embedded mixing system. This allows any cuts and mixes to be totally controlled by the automation system, or alternatively it can be operated manually. This allows for audio dips, etc and there is also an external voice-over facility.

After the SDI A/B switcher is a fully featured downstream keyer. This is ideal for operation with graphics equipment including character generators and stillstores. The DSK can provide additive and full linear keying facilities using both internal/external SDI key and fill signals. It also has operational control of gain, clip, and transparency levels, which are all totally independent.

presTX is compatible with all the current automation standards and is designed to be proactive. It also has programmable GPI interfaces, and its simple building block structure enables Eyeheight to tailor our software to suit every client. The control panel also uses a building block concept and can be used with the different features of presTX, all under automation control. This means that only one panel need be required for multiple installations. The panel is in fact, five different control panels, and these can be mixed and matched for total flexibility to the clients individual requirements.

Where will I find Eyeheight user manuals?

You can download user guides for most of the popular Eyeheight products from the Manuals link on the Support page of our web site.

Some Eyeheight function cards are supplied as dual devices. How are dual device cards controlled?

geNETics products are available as dual function cards. Single function devices with a –1 suffix can generally be doubled up on one processor and I/O card, although it is also possible to combine different devices which both have a –1 suffix on one card.

These dual cards are controlled using an FP-9 or FP-10 panel in the same way as other devices. The difference is that both are controlled as if they were one device. Settings applied by the user via the control panel are applied to both devices on the same card.

In the case of a dual safe area generator (SA-1D) for example, both SA-1 channels are set to work identically, and cannot operate separately.

The Eyeheight flexiPanel (FP-9) has eight device buttons but the flexiBox (FB-9) has six device cards. Why the extra two buttons?

The flexiPanel can control up to eight devices, two of which can be in a second flexiBox. This is simple and convenient way of adding to the flexibility of the system without having to use another control panel.

How is a function card controlled when using the Eyeheight miniBox?

The miniBox (MB-9) is a small half rack wide enclosure designed to hold just one function card. With an Eyeheight function card fitted, it makes up a low cost desk-top system

The miniBox is equipped with 5 front panel switches, (4 numbered switches and a "Fn" switch). These are used to recall the memory settings on the particular function card. The number of memories that can be accessed depends on how many memories each function card has but this allows the user to access up to 8 memories in total. Memories 1-4 are recalled by pressing switches 1 through 4. Memories 5-8 are recalled by holding the "Fn" switch down and pressing the 1 through 4 switches.

The switches can be programmed using a flexiPanel (FP-9) connected via the 9-way I-Bus connector on the front panel of the Mini-Box. Once the desired settings for each memory have been decided, they are stored in the required memory (number 1 - 8). The Flexi-Panel is then disconnected from the miniBox which is operated completely stand-alone from then onwards, the user changing the operation of the function card inside by recalling different memories by the front panel switches.

Using the equipment in this way means it is no longer possible to use the usual menus and parameter adjustments that can be made when using the 1 U flexiBox (FB-9) and flexiPanel (FP-9) with function cards.

External control of the miniBox is also possible by means of the Ext. Sw. connector which allows direct hard-wired momentary switch connection to take place in parallel with the numbered front panel 1-4 and "Fn" switches. Open collector outputs are also provided for external LEDs to be connected, to indicate which switch number has been activated.
