Being part of a larger research program, this paper focuses on the impacts of so-called 'Digital Video Recorders' (DVRs) on the video content services industry. First, it gives a succinct definition of the video content services industry using the value chain as a metaphor. After laying a brief theoretical foundation on technological change and adoption, it considers the technological factors '...

Providing valuable recommendations in the DVR domain is quite straightforward when enough information about users and/or contents is known. In this work, we discuss the possibility of recommending future live events without knowing anything else but past user programmed recording sched-

objective: this study compared the tension-free vaginal tape (tvt) and transobturator tape (tot) procedures for surgical treatment of stress urinary incontinence in women. materials and methods: this prospective non randomized clinical trial was conducted in vali-e-asr hospital from march 2001 to march 2005. a total of 71 patients with clinical and urodynamic diagnosis of stress urinary inconti...

The standard electrocardiogram is a sampling of but a small portion of the daily cardiac activity, and is only standardized for the supine position and the basal state. Such technique is not likely to reveal transient disturbances of cardiac rhythm and ST-T segment configuration. Accordingly, interest has been directed towards obtaining prolonged electrocardiographic recordings in ambulatory pa...

A scheme for domain and task representation in an interactive learning environment is described. The approach, based on recent enhancements to a classic AI planning formulation, enables suitable feedback to be incorporated economically into tutors for a range of procedural domains. The method is applied to the problem of simulating the operation of a video cassette recorder and representing tas...

Face-to-face dialogue is the basic site of language use. Our group’s program of research focuses on unique features of face-to-face dialogue, especially the ways in which participants collaborate moment-by-moment (e.g. Bavelas et al., 1995; Bavelas and Chovil, 1997; Bavelas et al., 2000, 2002). Current experiments are showing that the availability of collaborative processes in dialogue signific...

This report presents the development process of a web-based digital video recorder system (DVR). The conventional DVR system is mainly designed and used for local program recording. We developed a new DVR system that can be accessible from any where in the world through the web interface. By using the new system, a user can record and watch TV programs across countries.

In many computer vision applications such as surveillance systems, detecting moving objects is the first step of information extraction. This paper introduces a query answering system that aims at responding to user queries without the need to scan the whole video tape. The proposed system is based on finding the minimum boundary rectangles (MBRs) of moving objects which appear in the video. It...
