SOLUTION FOR MULTIMEDIA TELEVISION SYSTEM AS AN EDUCATIONAL LABORATORY
Keywords:
TV studio, Laboratory, Video system, Internet protocolAbstract
The paper provides a functional solution for the implementation of multifunctional and multimedia TV systems from a technical aspect. The multimedia TV system can be used in the educational process and in TV content production. The paper shows structure of a TV system, a functional block diagram of implemented video and audio system with enabled connections of the devices in the system. In the paper is presented a method for connecting with other television stations, as well as live broadcasting from the field using different protocols. The implemented TV system is designed to produce content of various video formats, so that content can be transmitted and produced up to 4K resolution. The laboratory is designed so that all the signals that are received and sent can be analyzed and measured. The laboratory is implemented at a higher education institution and can be implemented in other educational institutions, as well as in professional television stations.
