RESUMO

The purpose of this work is the development of a transmission platform with a graphical interface and software, using a TV channel of Brazilian Digital Television Standard (SBTVD) to transmit encapsulated data, audio and video. Initially is presented the SBTVD, with major highlight for multiplexing, given its importance in identifying and decoding the received signal. Within the transmitted bitstream there are certain tables that are responsible for identifying the information type present in the channel, being the most important detailed in this work. To make easy this configuration is presented the graphical interface to configure a channel in two situations: encapsulated data in ethernet format and audio/video content. Beside this, are compared the efficiencies of utilizing the packing control of multiprotocol encapsulation, that is used to transmit data in ethernet format. Also is presented an exploratory study of efficiency of bit rate related with the addition of the necessary headers to transmit correctly the signal in ethernet format inside the SBTVD transport protocol.
