Transport Stream Generator and Player for Digital Terrestrial Television ISDB-Tb
Gonzalo Olmedo, Freddy Acosta, Nancy Paredes, R.A Mena · 2015
The current paper introduces software, named Celina, that integrates the three ISDB-Tb standard functional blocks: Source coding block, multiplex block and transmission coding block. Celina allows to generate the MPEG-2 Transport Stream and transmit it by controlling the modulator DekTec DTU-215 functionalities. Therefore, users can manipulate transmission parameters and can broadcast the Transport Stream previously generated through a Radio Frequency channel. The first stage of the project uses bit level operations which perform the audio and video coding. The EWBS descriptor and the ISDB-Tb program-specific information tables are generated and implemented during the multiplex block. The second stage of the project handles a dynamic-link library, developed on C++, which utilize the most important DTU-215 modulator features. All of this features are embed in an easy- to-manage, scalable, Java graphic interface application.
