Abstract
The emergence of Interactive Digital Television (iDTV) opened a set of technological possibilities that go beyond those offered by conventional TV. Among these opportunities we can highlight interactive contents that run together with linear TV program (television service where the viewer has to watch a scheduled TV program at the particular time it is offered and on the particular channel it is presented on). However, developing interactive contents for this new platform is not as straightforward as, for example, developing Internet applications. One of the options to make this development process easier and safer is to use an iDTV simulator. However, after having investigated some of the existing iDTV simulation environments, we have found a limitation: these simulators mainly present solutions focused on the TV receiver, whose interactive content must be loaded in advance by the programmer to a local repository (e.g., Hard Drive, USB). Therefore, in this paper, we propose a tool, named BiS (Broadcast iDTV content Simulator), which makes possible a broader solution for the simulation of interactive contents. It allows simulating the transmission of interactive content along with the linear TV program (simulating the transmission of content over the air and in broadcast to the receivers). To enable this, we defined a generic and easy-to-customize communication protocol that was implemented in the tool. The proposed environment differs from others because it allows simulating reception of both linear content and interactive content while running Java applications to allow such a content presentation.
Highlights
Digital technologies dissemination in many knowledge areas led to changes in implementation of most modern society activities such as work, education, health, and entertainment
Among the main benefits offered by Digital TV, we can highlight audio and video quality improvement and the inclusion of new services such as interactive TV
The main feature of these systems is the capability of running applications that have been downloaded as part of the broadcast stream and synchronized with linear TV program: this is what makes the distinction between an interactive TV system and other TV systems [1,2,3]
Summary
Digital technologies dissemination in many knowledge areas led to changes in implementation of most modern society activities such as work, education, health, and entertainment. Among the main benefits offered by Digital TV, we can highlight audio and video quality improvement and the inclusion of new services such as interactive TV (iDTV). The main feature of these systems is the capability of running applications that have been downloaded as part of the broadcast stream and synchronized with linear TV program: this is what makes the distinction between an interactive TV system and other TV systems (basic digital or Smart TV) [1,2,3]. The major reasons for the use of simulation environments are International Scholarly Research Notices cost reduction to purchase real environments, increasing the speed of development, and security (once an application is under test could only cause harm to a virtual environment)
