Novel Approach in Distance Education using Satellite Broadcast (original) (raw)
Limited infrastructural support and lack of adequate teachers demand for a distance education system which can be used to augment the learning of students especially in rural areas of India and other developing countries. We propose novel technological methods to create a solution for distance education which uses existing wide spread satellite broadcast TV network. The solution has two additional components namely a content creator in the broadcast end and a low cost Home Infotainment Platform (HIP) [2] device in the user end. Apart from the video and audio, the associated metadata related to the question-answers (QA) and Electronic Program Guide (EPG) of the tutorials are also transmitted from the broadcast end. A method is proposed to embed the metadata as part of the video frame so that it is accessible in the analog input of the HIP client box. A detailed analysis on the effect of noise demonstrates the sustainability of the metadata in the analog video frame for the existing end to end TV broadcast network.
