IPTV testing is the performing of measurements or observations of a device, system or service that provides television service through data networks to validate its successful operation and/or performance. IPTV testing can be complicated because there are many interrelated processes which all can reduce the quality of the media and processes that are used to control the media flow.

IPTV systems differ from broadcast television systems as they use transmission systems that provide varying levels of performance. Broadcast systems are designed for controlled continuous transmission while IPTV systems use packet transmission that is subject to varying transmission patterns and packet losses (burst errors).

IPTV Connection - single packet stream with varying packet delays and losses.

IPTV Layers - commands and processes grouped into functional layers.

Quality of Service (QoS) - measuring network and device performance.

Quality of Experience (QoE) - measuring consumer satisfaction.
