Abstract

Purpose

The purpose of this paper is describing the seamless integration of the question‐answer interaction into automatic lecture recordings (ALRs). This includes the design and implementation of the question management (QM) software for a virtual camera team.

Design/methodology/approach

Coming from the human role model the interaction and its management to the virtual world is transferred and integrated it into a virtual camera team. All events are translated into sensor inputs which get processed by the virtual director and are used for the collaboration of the team in order to implement more complex cinematographic rules.

Findings

It is found that it is possible to record the whole interaction, to record the original voice of the questioner out of an audience without handing out a microphone or forcing him/her to walk to one, and to record a video of the questioner while asking. So, it is easier to follow a lecture recording as more details are recorded automatically.

Practical implications

First experiences on using this software clearly show the small weaknesses of the first version. As mentioned in the outlook, these are currently being addressed, e.g. by looking for a more natural interface.

Originality/value

The paper demonstrates how to use the question‐answer interaction as sensor input for an automatic lecture recording (ALR) system based on the roles of the according human originals. It ensures that many details of a lecture can be recorded seamlessly to keep the lecture context continuous and therefore to make the lecture recording more vivid and interesting.

Abstract

Purpose

The paper aims to examine the expanding broadband “digital divide” as a warning that developing countries are falling behind in the upgrade of their telecommunication networks, specially the access network. It points out the deteriorated financial conditions facing developing countries in the context of the global economic crisis that adversely affects the availability of resources to invest in network infrastructure.

Design/methodology/approach

The paper is based on a review and analysis of relevant literature and the outcomes of significant ICT for development events.

Findings

The existing economic mechanisms in international communications networks establish the financial flows in favor of the developed countries, thus thwarting any attempt to increase its net external income that could be used in investments in telecommunications infrastructure. On the other hand, convergence and the migration to next generation networks present a new set of opportunities and challenges to establish an international interconnection regime that will allow the developing countries to recover the investment in infrastructure.

Research limitations/implications

The scarcity of publicly available economic data of the current international interconnection agreements suggests the necessity to conduct further research in this area.

Practical implications

The failure to establish a non‐discriminatory international interconnection regime could lead to economic unsustainability of international networks in the long run. The paper presents some recommendations to address this issue.

Originality/value

This paper presents an approximation to an important issue of international telecommunication networks that is usually hidden behind the confidentiality of services contracts.
