4.1 ROOM CLASSIFICATION
In order to maintain a level of consistency for end users as well as maintenance staff, a University wide design
strategy has been developed to establish a set of standard formats for teaching spaces and the associated AV
facilities. Venues with AV devices will be classified as one of the following formats as described in the table
below. Specialist and other spaces may fall outside of the standards covered in this document. In these
instances, a bespoke design will be completed to provide the required functionality. These bespoke designs,
where possible, will be derived from the standards and preferred equipment lists detailed in this document.
The new designs incorporate the current digital AV technologies such as HDMI, wide screen projection (16:10)
and higher resolutions (WXGA1280:800 & WUXGA1920:1080). To allow for greater flexibility within a general
teaching space devices such as Bluray players and document cameras are now peripheral based and are
connected to the AV system via the resident PC. i.e. USB for document cameras and in the case of the Bluray
provided with the resident PC. Larger spaces such as lecture theatres will still utailse standalone devices.
The new designs are a total digital solution and provide legacy support for VGA connectivity. No direct support
is provided for older analogue signals such as Composite (CV), Component (YP
B
P
R
, YUV, RGB), S-Video etc.
These signals will be “scan converted” to digital prior to connection to the AV system. In the short term
portable scan converters are available by contacting the AV department via the service desk.
Room functionality from the previous AV standards has been maintained or increased due to peripheral based
devices and adoption of HDMI. This allows the designs to be aligned to the size of the room. The standards
also include designs for use in meeting and office spaces where there is less demand on the AV system and
accessories such as remote controls are easily secured. This means that Pro-domestic LCD panels can be
installed and generic remotes used as the control systems. The new standards are not a one-for-one
replacement of the old and the following table shows the correlation between the two.

We note that these categories are by no means all-encompassing, as there are some AV facilities that fall
outside these classifications. The classifications are as follows:

(interactive)
AV00-20P

The simplest of the AV enriched space, designed for small meeting space and
includes:
− A large format LCD panel, projector or interactive whiteboard as the primary
display device. The projection and interactive whiteboard system will include
surface mounted front of house speakers to reinforce audio, the LCD panel will
utilise integrated speakers.
− There will be provision to connect a resident University PC and Laptops (VGA
and HDMI).
− Bluray/DVD playback will be via the resident PC
− A USB document camera may be provided if a resident PC is installed
− Control for the room’s AV equipment including source selection and audio
levels will be controlled by a wall mounted eight-button keypad controller. The
keypad controller shall be typically installed on the wall adjacent the display
