DESIGN OF A RECEIVER OF MPEG TRANSPORT STREAM FOR ETHERNET NETWORKS

Ariel Catalá Valencia, Reinier Díaz Hernández

Abstract


The design of a platform that receives MPEG streams through IP networks and is capable of retransmitting them is vital for the transmission of multimedia content over this type of networks, which are inherently heterogeneous. This work focuses on the selection of the most suitable mechanism for this, as well as on the processing of such streams in the designed platform. The streams processing contributes to mitigate the negative effects of heterogeneous networks on audio and video transmissions. This design is carried out in software using the Simulink tool. To validate the design, a transmission through an IP network of streams generated with the FFmpeg software is simulated. The results were obtained with the Wireshark tool and the Simulink logic analyzer. These results demonstrate that it is possible to perform such processing with the proposed design. However, its implementation in software is not efficient enough for its use due to the delays introduced. To solve this problem, the implementation of the current design on a hardware platform is proposed for future works.
