Bitstream-based methods are intuitively suited for quality assessment of networked video
services, and are currently under intense investigations in terms of research and …

The use of adaptive-bitrate-streaming services over networks has been increasing in recent
years. The quality of adaptive-bitrate-streaming services is primarily affected by the video …

This paper presents a quality of experience (QoE) conceptual model to the context of unified
communications (UC) through summary, classification, and discussion of multiple influence …

Mobile videos on smartphones have been widely used and enjoyed by increasing numbers
of people in recent years; however, due to the high bit rates of video streams, viewers must …

Packet-layer models are designed to use only the information provided by packet headers
for real-time and non-intrusive quality monitoring of networked video services. This paper …

In this paper we analyze how the frame rate affects the video perceived quality for different
video contents. Combining these results with our previous work, a new parametric model is …

Since the quality of video streaming services is degraded due to the encoding, network
congestion, and lack of a playout buffer, the normality of services needs to be monitored by …

Sažetak Long term evolution (LTE) is the fastest-deployed mobile broadband technology
driven by demand for improved user experience. It has distinguished itself compared to …

Packet loss is of great importance as a metric that characterizes the network's performance,
and is crucial for video applications, congestion control and routing. Most of existing …

Today user experience is becoming a reliable indicator for service providers and
telecommunication operators to convey overall end to end system functioning. Moreover, to …
