Video distribution over error-prone Internet Protocol (IP) networks results in visual impairments on the received video streams. Objective impairment detection algorithms are crucial for maintaining a high Quality of Experience (QoE) as provided with IPTV distribution. There is a lot of research invested in H.264/AVC impairment detection models and questions rise if these turn obsolete with a transition to the successor of H.264/AVC, called High Efficiency Video Coding (HEVC). In this paper, first we show that impairments on HEVC compressed sequences are more visible compaired to H.264/AVC encoded sequences. We also show that an impairment detection model designed for H.264/AVC could be reused on HEVC, but that caution is advised. A more accurate model taking into account content classification needed slight modification to remain applicable for HEVC compression video content.
在易出错的互联网协议(IP)网络上进行视频分发会导致接收到的视频流出现视觉障碍。客观损伤检测算法是在IPTV分布条件下保持高质量体验(QoE)的关键。在H.264/AVC损伤检测模型上投入了大量的研究，如果这些模型随着H.264/AVC的继任者——高效视频编码(High Efficiency Video Coding, HEVC)的过渡而过时，问题就会出现。在本文中，我们首先证明了HEVC压缩序列的损伤比H.264/AVC编码序列更明显。我们还证明了为H.264/AVC设计的损伤检测模型可以在HEVC上重复使用，但建议谨慎使用。考虑到内容分类的更精确的模型需要稍加修改才能适用于HEVC压缩视频内容。

Since privacy issues are becoming important with growth of the video surveillance, many tools are proposed for protection of personal privacy in the video. However, little is understood regarding the effectiveness of such tools and their effect on the underlying surveillance tasks. In this paper, we propose a subjective evaluation methodology that compares several popular privacy protection techniques applied to typical indoor surveillance video. We identify and analyze the tradeoff between the privacy preservation of these tools and the intelligibility of activities in the resulted surveillance video.

Multimedia is ubiquitously available online with large amounts of video increasingly consumed through Web sites such as YouTube or Google Video. However, online multimedia typically limits users to visual/auditory stimulus, with onscreen visual media accompanied by audio. The recent introduction of MPEG-V proposed multi-sensory user experiences in multimedia environments, such as enriching video content with so-called sensory effects like wind, vibration, light, etc. In MPEG-V, these sensory effects are represented as Sensory Effect Metadata (SEM), which is additionally associated to the multimedia content. This paper presents three user studies that utilize the sensory effects framework of MPEG-V, investigating the emotional response of users and enhancement of Quality of Experience (QoE) of Web video sequences from a range of genres with and without sensory effects. In particular, the user studies were conducted in Austria and Australia to investigate whether geography and cultural differences affect users' elicited emotional responses and QoE.

This paper presents mapping of Received Signal Strength Indicator (RSSI) to Quality of Experience (QoE) in mobile devices for end to end VoIP communications over Wi-Fi. Through extensive experiments, relationships between RSSI and QoE were investigated and a mapping table from RSSI to QoE was created. The effectiveness of the proposed approach in terms of energy saving was also demonstrated by comparing it with conventional QoE monitoring approach.

Currently, the large majority of 3D display solutions rely on binocular perception phenomena. Furthermore, while 3D display technologies are already widely available for cinema and home or corporate use, only a few portable devices currently feature 3D display capabilities. In this paper, we study the alternative methods for restitution of 3D images on displays of commercially available portable devices and analyse their respective performance. This particularly includes the restitution method which uses multiscopic image data-set and which relies on motion parallax as an additional depth cue. The goal of this paper is to compare three different commercially available 3D display techniques, the auto-stereoscopic and anaglyph method which provide binocular depth cues and a method based on motion parallax. The subsequently conducted subjective quality tests show that the motion parallax based approach to present 3D images on consumer portable screen is an equivalent and quite competitive way in comparison to the above mentioned stereopsis based methods.

Transmission errors are the main cause of degradation of the quality of real broadcasted video services. Therefore, knowing their impact on the quality of experience of the end users is a crucial issue. For instance, it would help to improve the performance of the distribution systems, and to develop monitoring tools to automatically estimate the quality perceived by the viewers. In this paper we validate a subjective evaluation approach specifically designed to obtain meaningful results of the effects of degradations caused by transmission errors. This methodology has been already used in our previous works with monoscopic and stereoscopic videos. The validation is done by comparing the subjective ratings obtained for typical transmission impairments with the proposed methodology and with the standard method Absolute Category Rating. The results show that the proposed approach could provide more representative evaluations of the quality of experience perceived by end users of conventional and 3D broadcasted video services.

Multimedia presentations are expected to show a higher performance in communicating complex and relational information than single media presentations. In this case study, we evaluate the performance of multimedia presentations of radiological findings in communicating propositional facts about a patient's health status. In collaboration with experts and future users, three radiological communication tools have been developed which differ with respect to the presentation media and interactivity. These tools have been evaluated in a controlled user study concerning their efficiency in communicating propositional facts, as well as concerning their usability in the clinical praxis. The results show a slightly higher efficiency of the audiovisual compared to textual or visual-only presentation, and a preference of users for the interactive audio-visual or visual tool.

A common guideline for Quality of Experience (QoE) testing is to present the whole range of low and high quality test clips in order to avoid rating biases. We present a comparative empirical study in the context of HD IPTV services, in which one group of participants exclusively viewed high-quality video clips, and the other group additionally were confronted with low-quality clips. We only found a very weak effect of clip quality distribution on rating behavior and thus cannot confirm the recommendation for including low-quality clips in HD video QoE evaluations.

Common methods to determine the quality of media rely on conscious ratings of a subject's opinion about the quality of presented stimuli. While such methods provide a reliable and valid means of determining quality, they provide little insight into the physiological processes preceding the quality judgment, which, however, may affect the subjective behavior, e.g., in terms of alertness or media usage duration. In this paper we used a non-intrusive physiological method, electroencephalography, to assess the cognitive state of subjects related to the quality of auditory speech stimuli. We show that users listening to degraded audio rated the quality lower in comparison to an undisturbed stimulus as expected and, in addition, got more fatigued during the 20 minute presentation. Indicators of the increased fatigue were Theta and Alpha frequencies of the electroencephalogram data. The results show that the perception of degraded media has long-term influences on physiological processes at the time scale of minutes which may immediately influence customer behavior.

There has been much recent interest, both from industry and research communities, in 3D video technologies and processing techniques. However, with the standardisation of 3D video coding well underway and researchers studying 3D multimedia delivery and users' quality of multimedia experience in 3D video environments, there exist few publicly available databases of 3D video content. Further, there are even fewer sources of uncompressed 3D video content for flexible use in a number of research studies and applications. This paper thus presents a preliminary version of RMIT3DV: an uncompressed HD 3D video database currently composed of 31 video sequences that encompass a range of environments, lighting conditions, textures, motion, etc. The database was natively filmed on a professional HD 3D camera, and this paper describes the 3D film production workflow in addition to the database distribution and potential future applications of the content. The database is freely available online via the creative commons license, and researchers are encouraged to contribute 3D content to grow the resource for the (HD) 3D video research community.
