RESUMO

The great evolution in the telecommunication systems related to the transmission of multimidia contents in the data communication networks and TV transmission, demands management solutions in which regards quality of end-to-end services. Taking this scenario into consideration, it is proposed in this work the definition and implementation of a solution to monitor media transmition that can be applied to heterogeneous network architectures. The feature of such networks is to integrate different data communication network technologies and telecommunication, involving legacy and modern networks, standarized and proprietary. This work presents a monitoring system for digital TV transmission in heterogeneous converging environments, that is, networks that use different technologies and transmission means for the Digital TV application. Therefore, key aspects for monitoring the digital TV flow in this kind of network are pointed out, as well as an analysis of the communication among the environment subsystems. The monitoring system has a defined architecture, based on the RTP Real-time Transport Protocol, to support the media transmission, such as audio and video, in heterogeneous networks. In order to validate this architecture, a prototype was implemented, as concept evidence, that obtains data from the management information base (MIB) RTP. The results generated by the prototype consolidate information related to the delay variation (jitter) in a management web interface through monitors distributed around the network.
