*SCQF credit points are used to allocate credit to qualifications in the Scottish Credit and Qualifications
Framework (SCQF). Each qualification in the Framework is allocated a number of SCQF credit points at an
SCQF level. There are 12 SCQF levels, ranging from Access 1 to Doctorates.
Recommended prior knowledge and skills: While access to this Unit is at the discretion
of the centre, it would be beneficial if candidates had prior experience of using a computer system at
SCQF level 5. Examples would be: D1D0 11 Multimedia Computing: Introduction to Video
Production, D6RC 11 Introduction to Computer Animation or DO1D 11 Information Technology.

Communication, Problem Solving at SCQF level 6 in this Unit, although there is no automatic
certification of Core Skills or Core Skills components.
Context for delivery: If this Unit is delivered as part of a Group Award, it is recommended that
it should be taught and assessed within the subject area of the Group Award to which it contributes.
The Unit could be taught contiguously with DH4D 34 Audio Visual Presentation 1: Introducing
Audio Visual Presentation.
Assessment: Outcomes 1, 2 and 3 may be assessed holistically by a project or report of 1500

Assessment Guidelines
The assessment event for Outcomes 1, 2, and 3, may take the form of an integrated project brief
requiring the candidate to produce a report of 1,500 words or equivalent, using diagrams or images as
appropriate to explain the technology. Reports may be styled according to suitable word processing
templates. Case studies may be used for guidance in producing the final report, and may be sourced
from web derived sources with correct attribution of sources as appropriate.
Outcome 3 may be assessed as a separate assessment event in a 500 word report from a candidate’s

Higher National Unit specification: support notes
Unit title: Audio Visual: Introduction to Audio Visual Technology
This part of the Unit specification is offered as guidance. The support notes are not mandatory.
While the exact time allocated to this Unit is at the discretion of the centre, the notional design length
is 40 hours.
Guidance on the content and context for this Unit
The purpose of this Unit is to provide the candidates with an introductory overview to this subject
area, which will allow the candidate to study specialised Units within the area. Computer
competencies should be integrated into the creative process, and lecturers should be encouraged to
update the resource database as the software and hardware evolves in this dynamic subject area.
Outcome 1
This Outcome encourages the candidate to develop a broad understanding of audio and video signals,
how they apply in practice, and how the data is stored. A popular MSD is the computer hard disk, and
candidates should show awareness of current developments in this area, and be familiar with the
concept of RAID systems. RAID refers to Redundant Array of Inexpensive/Independent Disks, a
category of disk drives where two or more hard disk drives are used to ensure that data is safely
stored. There are different levels of RAID; however, RAID 5 is the most popular.
Outcome 2
This Outcome encourages the candidate to develop an awareness of basic principles of broadcasting
as currently used, with the candidate being able to describe the analogue and digital signal process,
how a broadcast image is displayed, and the role of pixels in image acquisition. Candidates should be
able to demonstrate knowledge of HDTV and internet protocol television over a network
infrastructure. The concept of broadcasting is not to be interpreted exclusively in the context of
terrestrial broadcasting. The abbreviation IPTV commonly refers to Internet Protocol Television,
where a digital television service is provided using the internet protocol over a network infrastructure.
IPTV covers both multicasting (live TV) and VOD, Video on Demand. VOD uses an mpeg2 or 4
codec sent via an mpeg2 transport stream via IP Unicast. Other codecs will become prominent during
the life of this Unit, and should be incorporated accordingly. NVPR is Network Personal Video
Recording, a type of time shifted broadcast recording off a server.
Outcome 3
This Outcome encourages the candidate to research and describe the technical specifications
underpinning a range of AV equipment commonly used in sectors of the AV industry, and describe
their practical application, including lighting the set with portable lighting. This Outcome encourages
the candidate to explore a range of ideas and possibilities in relation to audio visual display systems
and their interaction with each other in responding to a client brief.
Guidance on the delivery and assessment of this Unit
Outcomes 1, 2 and 3 may be assessed holistically by a project or report of 1,500 words or equivalent.
Alternatively, individual reports could be used to assess Outcomes 1 and 3, with Outcome 2 being
assessed by the use of restricted response questions.

Opportunities for developing Core Skills
There are opportunities to develop the Core Skill of communication at SCQF level 6 if the candidate
submits a report for all of the Outcomes. There may be opportunities to develop the Core Skill of
problem solving at SCQF level 6 when the candidate applies knowledge in researching and deriving
technical specifications in response to the project brief. There are opportunities to develop the Core
Skill of Information Technology at SCQF level 6 if the candidate uses the Internet in their research
and uses software packages in the evaluation and collation of complex information in the form of
relevant research and technical materials.
Open learning
This Unit could be delivered by open learning provided the candidate had access to the appropriate
hardware and software required by the Outcomes. Arrangements would have to be made with the
delivering centre for the candidate to be supervised for the Outcome 2 assessment.
Candidates with disabilities and/or additional support needs
The additional support needs of individual candidates should be taken into account when planning
learning experiences, selecting assessment instruments, or considering alternative Outcomes for Units.
Further advice can be found in the SQA document Guidance on Assessment Arrangements for
Candidates with Disabilities and/or Additional Support Needs (www.sqa.org.uk).

General information for candidates
Unit title: Audio Visual: Introduction to Audio Visual Technology
This Unit introduces you to the broad basic principles of audio visual technology. By the end of the
Unit you should be able to:
1
2
3
Explain the principles of audio, video, and storage technology.
Explain the principles of broadcasting.
Research and explain audio visual systems for presentations.
Outcome 1 introduces you to an understanding of Analogue and digital signals, their advantages and
disadvantages. You will discover what comprises a video signal, the transmission of digital stereo
sound, how a camcorder operates, and various storage media such as computer hard disks. You will
become familiar with the concept of RAID systems. RAID refers to Redundant Array of
Inexpensive/Independent Disks, a category of disk drives where two or more hard disk drives are used
to ensure that data is safely stored.
Outcome 2 will enable you to have an understanding of how pixels operate in the creation of images.
How HDTV works as compared to non HDTV will be examined, and why HDTV has become
increasingly prominent. Visual display units permeate many aspects of modern audio visual, so we
will look at how computer data is displayed visually. As broadcasting systems expand, we will look at
internet protocol television, and its related developments such as server based time shifting for
consumer television.
Outcome 3 will help you to become familiar with a range of hardware and software involved in audio
visual production, and you will research a technical specification for the appropriate hardware, which
may include laptop computers running presentation software, PS systems, LCD projectors,
camcorders, video conferencing system, and the ubiquitous redhead luminaire.
The knowledge and skills you acquire in this Unit should help you understand the learning involved
in subsequent Units of a more specialised nature that will deepen your understanding of audio visual
technologies.
