Comparation of QoS parameters of received IPTV signals, using different compression algorithms for streaming Live or Stored AV Materials

Abstract

Importance of digitalization of AV (audio/video) signals, produced in TV studios, has been recognized long time ago, and in many countries, TV studios abandoned old analog transmission, leaving place for digital signal transmission. In Bosnia and Herzegovina, TV studios are still producing and broadcasting analog PAL signal, but according to recommendation, they should switch to DVB before 2012. Because of the actuality of this problem, the main idea of this paper was to make appropriate hardware and software solution for digitalization of PAL signal, acquired on the output of analog cameras or stored on tapes in studios, and its transmission over IP based network, together with application on client side. Using developed solutions on server and client sides, different types of compression and container formats are tested, in order to recommend TV stations the solution for producing digital AV signals with the best quality for end users, in future DVB network.
