TL;DR: Experimental results show that the summaries are largely reduced and that the perceived video quality may be comparable to the one of the original video (in term of jerkiness), and consumers satisfaction has been investigated through MOS and results show That summaries can be considered as an alternative to the original videos.
Abstract: The availability of video files in the Internet is growing at an exceptional speed and in the near future video browsing will be a common activity. To facilitate such activity it will be necessary to have a small clip for any given video. Currently, video skimming and video summarization techniques can reduce the temporal representation of a given video. However, most of these techniques do not include audio in the produced summaries. Here, we propose a mechanism that, using audio and video analysis, produces video summaries coupled with intelligible audio. Experimental results show that the summaries are largely reduced (up to 50%) and that the perceived video quality may be comparable to the one of the original video (in term of jerkiness). Consumers satisfaction has been investigated through MOS and results show that our summaries can be considered as an alternative to the original videos.

TL;DR: This article considers MP3 audiobook applications and proposes an approach to completely restyle the applications to the current mobile and multimedia scenario and introduces multimedia contents into the audiobook application and synchronizes them with the MP3 audio stream.
Abstract: Portable devices and wireless connections are creating a new scenario in which digital information is entering our lives in a massive way. In this article we consider MP3 audiobook applications and propose an approach to completely restyle the applications to the current mobile and multimedia scenario. Our mechanism introduces multimedia contents (images and text) into the audiobook application and synchronizes them with the MP3 audio stream. Multimedia contents are protected by a security system that ensures perfect audio quality and full access to multimedia contents only to a legal user. A distribution architecture and a player that use the proposed mechanism are also presented.

TL;DR: This paper proposes a mechanism that integrates low and high level video features to provide a high level semantic description and an experimental evaluation shows the benefits of integrating audio and video analysis.
Abstract: The high availability of video streams is making necessary mechanisms for indexing such contents in the Web world. In this paper we focus on news programs and we propose a mechanism that integrates low and high level video features to provide a high level semantic description. A color/luminance analysis is coupled with audio analysis to provide a better identification of all the video segments that compose the video stream. Each video segment is subject to speech detection and is described through MPEG7 so that the resulting metadata description can be used to index the video stream. An experimental evaluation shows the benefits of integrating audio and video analysis.

TL;DR: This paper analyzes the mobile music distribution strategy focusing on: the communication infrastructure, the pricing strategy and the copyright protection, and proposes a multi-channel distribution approach that makes use of both the cellphone network and the free-of-charge communication technologies provided in cellphones.
Abstract: The music industry is planning to perform a significant shift toward the digital world by partnering cellphone network operators to build a mobile music market. In this paper we analyze the mobile music distribution strategy focusing on: the communication infrastructure, the pricing strategy and the copyright protection. Results of our analysis show that the strategy may be questioned and hence we propose a multi-channel distribution approach that makes use of both the cellphone network and the free-of-charge communication technologies provided in cellphones. Our multi-channel distribution strategy is coupled with an incentive mechanism that stimulates customers cooperation in the mobile scenario. An evaluation of our approach shows that all the entities involved in the mobile music distribution (customers, cellphone network providers and music stores) can benefit from using a multi-channel distribution approach.
