Question 13/12 - QoE/QoS performance requirements and assessment methods for multimedia including IPTV
(Continuation of Question 13/12)
Motivation
A major challenge for emerging IP-based networks is to provide adequate Quality of Experience
(QoE) and Quality of Service (QoS) for new multimedia services and applications. As an example,
IPTV is a rapidly emerging new multimedia service. A key factor in achieving commercial success
for IPTV and also Home Networking Services will be to ensure that end-users will be satisfied with
the performance. These services are inherently multi-media, incorporating audio, video, text,
graphics, and interactive control functions, and performance requirements and associated measurement
methodologies for each of these aspects need to be defined.
The following major Recommendations/Supplements/Handbooks, in force at the time of approval of this Question, fall under its responsibility:
G.1010, G.1030, G.1040, G.1050
Question
Study items to be considered include, but are not limited to:
- Identify end-user performance expectations and associated metrics for audio, video, text, graphics quality and control functionality
- Define the key performance parameters and values required to satisfy end-user expectations.
- Determine how these requirements can be related to the underlying network transport level.
- Identify simple analysis techniques for estimating end to end performance for multimedia applications
- Identify QoS/QoE monitoring methodologies for multimedia services
- Traffic management considerations (e.g. admission control, priority, etc.)
- Identify methods for reducing the impact of transport impairments (e.g. packet loss, bit errors)
Tasks
Tasks include, but are not limited to:
- Development of new Recommendations providing guidance on end-user performance expectations
for multimedia applications, particularly IPTV and Home Networking Services
- Development of simplified planning models for estimating end to end multimedia performance
- Development of performance monitoring methods for multimedia services
- Development of application layer reliability solutions for multimedia services
