Standards Development
To develop an International Standards for requirements of user’s Quality of Experience (QoE)
for multimedia conferencing services.
With the global COVID-19 pandemic, the meetings on business and education have shifted
from offline to online modes. Consequently, a range of multimedia conferencing services has
been developed, enabling users to choose and enjoy conferencing services based on personal
preferences. To ensure optimal user experience, it is essential to measure the Quality of
Experience (QoE) for multimedia conferencing services.
However, there is currently a lack of standardized methods for measuring a user's QoE in this
context. Thus, there is a pressing need to provide guidelines for measuring and evaluating a
user's QoE for multimedia conferencing services.
Traditionally, Quality of Service (QoS) has been measured for network data communication,
represented by objective index values like delay, throughput, and jitter. In contrast, QoE
represents a user's level of satisfaction with a specific service and reflects human emotional
quality. As such, QoE is subject to overall service performance from the user's perspective. In
the case of multimedia conferencing services, measuring QoE is challenging due to varying
user preferences/requirements and service/application characteristics. Therefore, a unified
framework is necessary to measure and evaluate a user's QoE for multimedia conferencing
services.
This document (IEC 63478) aims to provide guidelines for enhancing a user's QoE for
multimedia conferencing services. The series specifies general considerations and
requirements to enhance a user's QoE and measurement methods for associated QoE
parameters.
The IEC 63478 consists of the following parts:
- Part 1: General;
- Part 2: Requirements; and
- Part 3: Measurement methods.
Part 1 of IEC 63478-1 (Technical Report) describes general considerations to measure user's
QoE.
Part 2 of IEC 63478-2 (International Standard) describes the requirements to be considered to
measure user's QoE.
Part 3 of IEC 63478-3 (International Standard) describes the measurement methods for QoE
parameters.
