Balancing the power of multimedia information retrieval and usability in designing interactive tv

Steady progress in the field of multimedia information retrieval (MMIR) promises a useful set of tools that could provide new usage scenarios and features to enhance the user experience in todays digital media applications. In the interactive TV domain, the simplicity of interaction is more crucial than in any other digital media domain and ultimately determines the success or otherwise of any new applications. Thus when integrating emerging tools like MMIR into interactive TV, the increase in interface complexity and sophistication resulting from these features can easily reduce its actual usability. In this paper we describe a design strategy we developed as a result of our efforts in balancing the power of emerging multimedia information retrieval techniques and maintaining the simplicity of the interface in interactive TV. By providing multiple levels of interface sophistication in increasing order as a viewer repeatedly presses the same button on their remote control, we provide a layered interface that can accommodate viewers requiring varying degrees of power and simplicity. A series of screen shots from the system we have actually developed and built illustrates how this is achieved.

Enhancing the Functionality of Interactive TV with Content-Based Multimedia Analysis

In this paper we describe how content-based analysis techniques can be used to provide much greater functionality to the users of an interactive TV (iTV) device. We describe several content-based multimedia analysis techniques and how some of these can be exploited in the iTV domain, resulting in the provision of a set of powerful functions for iTV users. To validate our ideas, we introduce an iTV application we developed which incorporates some of these techniques into a simple set of user features, in order to demonstrate the usefulness of content-based techniques for iTV. The contribution of this paper is not to provide an in-depth discussion on each of the individual content-based techniques, but rather to show how many of these powerful technologies can be incorporated into an interactive TV system.

Social recommendation and visual analysis on the TV

In this paper, we present prototype interactive TV software that incorporates visual content analysis tools and social networking in the home TV. We present the challenges of working with the living room TV environment and outline how we have utilized visual processing and search technologies to address these challenges and create a novel prototype interactive TV system.

Towards Multimedia Contents Management System on Consumer Electronics Devices

The need for the efficient handling of digital multimedia contents has increased tremendously as both home and mobile CE (consumer electronics) devices are equipped with large embedded storage such as hard disks or flash memories and are capable of handling enormous amounts of multimedia data. This paper presents Mint, an efficient multimedia contents management system for CE devices. It provides novel intuitive browsing and search interfaces by arranging multimedia data for various metadata. The system consists of the metadata extractors and the metadata core that are applicable to diverse hardware platforms and operating systems. Being applied to several CE devices has proved the usefulness of the system, especially for such devices as the digital TVs, set-top boxes and mobile phones
