Addressing User Expectations in Mobile Content Delivery

Abstract

Multimedia services like television programs and live streaming of mobile videos can be delivered to mobile terminals via different access technologies. The question is – how do users perceive such services on mobile terminals? The objective of this study is to find the correlation between video quality thresholds and the user context. Our study reveals the thresholds of user's quality of experience (QoE) in a mobile environment by using different categories of content types, in relation to different access technologies and terminal capability. The mobile terminals used are: – (i) 3G Mobile Phone (ii) Personal Digital Assistant (PDA) and (iii) Laptop. We argue that quality of service (QoS) management should be driven by the user perception of quality rather than resulting from raw engineering parameters such as latency, jitter, bandwidth etc. Our results will be of great interest to network operators, service providers, terminal manufacturers, and researchers working in the area of quality of service management.

Quality of experience management in mobile content delivery systems

“…This work extends previous findings reported in [1,2,5] and [3,6], which focused mainly on the collection of QoE data for different types of services. In [5] a QoE management methodology was proposed, which shows how QoE data may be used for the benefit of network operators.…”

Engineering wireless broadband access to IPTV

“…The protection pattern for redundant packets is accentuated compared to Paris, in the sense that providing duplicate redundant versions of more than just partition-A packets is now clearly seen to be preferable. Given that in quality-of-experience subjective tests for mobile devices [54], news scenes rather than sport are preferred by viewers, it may be advisable to favour content without rapid motion, especially if small footballs or similar sports' balls need to be tracked by the viewer.…”

Computational Inference and Control of Quality in Multimedia Services

“…The quality can be considered as acceptable as long as the change in parameters results in no perceivable difference using the method of limits [74]. In JND the smallest change in a parameter that results in detection is defined as 1 JND.…”

“…In a subjective study addressing the user expectations in mobile content delivery [74] the authors examined the acceptability of QoE, for different types of content and on three different devices, using the method of limits. Content types included: news broadcast, sports, video game animations, music videos and movies.…”

“…The subjective data is collected with the method of limits [74] and have two labels, 'acceptable' and 'not acceptable'. We consider different kinds of streamed content on three different terminals, as described in the previous chapters.…”
