Perceptual Quality Measurement— Towards a More Efficient
Process for Validating Objective Models
The Quality of Service Metrics
(QoSM) Committee of the
Alliance for Telecommunication
Industry Standards
(ATIS) Internet Protocol
Television (IPTV) In teroperability Forum
(IIF) is tasked with defining how objective
quality metrics can provide meaningful
IPTV performance measures. This
group has reviewed current objective
quality models as well as the processes
by which such models are validated.
This article describes current practices
in validating objective quality models
and presents a new, streamlined process
that can be implemented to achieve
more efficient and effective model validation.
Of main interest for IPTV are
models for predicting video and audiovisual
quality; however, the process also
applies to the validation of perceptual
quality models (PQMs) for other modalities.
The proposed process offers vendors
a fast route to validating objective
PQMs while providing industry with the
assurance of independent, unbiased
model evaluation. Read More...
