Experiments on Using MPEG-4 for Broadcasting Electronic Chalkboard Lectures
نویسندگان
چکیده
The MPEG-4 standard describes a multimedia format that allows to combine vector based data with audio and video. This makes it possible to store and transmit lectures created with the E-Chalk system without any loss of semantics. Utilizing the infrastructure already available for MPEG-4 promises the possibility of getting rid of a proprietary lecture format. This article presents the implementation of a converter tool that transforms E-Chalk lectures to MPEG-4. It shows the current possibilities for the replay of MPEG-4 based E-Chalk lectures and discusses technical problems and principal issues resulting from the use of this already aged standard.
