Aims
To explain the nature and composition of primarily baseband broadcast quality signals; to describe the operation of (and standards required for) broadcast equipment to recognised professional industry practice.
Learning Outcomes
1.
Identify and measure parameters of typical examples of broadcast quality signals.
2.
Explain the principles of studio and portable equipment and evaluate trade-offs in their selection and operation
3.
Analyse the nature of broadcast signals
Module Content
Outline Syllabus:Audio signals, transduction and parameters
Alignment and permitted maximum levels, signal decibels, international measurement scales
Phantom power arrangements, patching and connector systems to broadcast standards
Peak vs loudness monitoring, headroom standards, dynamic range compression
Digital audio sampling frequencies, aliasing and filtering, quantisation levels & noise
Inter- and Intra-studio Tx systems (e.g. AES/EBU)
Audio file formats, data rate, bit rate reduction & acceptable contribution delivery standards
Maximum Coding Level and digital headroom
Relationship between video and audio signals
Scanning, resolution, effect of Interlace, flicker, frame rates, shutter speeds, gamma

Colour vision and standards, luma & chroma signals
Component and composite signals, terminology, standard test signals, calibration
Digital video signals, (e.g. Rec 601/709), Sampling formats (e.g. 4:2:2) and harmonised sampling frequency, video quantisation levels & noise
DVE, captions, studio & OB layout and operations
Inter- and Intra-studio Tx (e.g. HD-SDI), signal paths: studio to consumer, storage, play-out
Image file formats, data rate, bit rate reduction, concept of asymmetric encoding/decoding & acceptable contribution delivery standards
Networks: What are they? Why do we use them? Packets; addressing; data; capacity; storage; bandwidth; delay; errors/corruption, data loss, QoS, Internet.
Nomenclatures, EBU emission recommendations, acquisition & storage
Additional Information:This module provides information on the nature and composition of primarily baseband broadcast quality
signals. It covers the professional operation of broadcast equipment and the standards required by broadcast organisations.
