Acesso em:.https://repositorio.ufpa.br/handle/2011/3757This thesis proposes the development of a planning strategy that combines: load characterization of a typical Digital TV, extraction of a weight vector from belief networks, and multicriteria decision making with analytical methods (TOPSIS and ELECTRE III), providing decision support at the service providers; in order to enable the optimal choice for the return channel technology (ADSL2 +, PLC, WiMAX and 3G), considering the typical load of an interactive Digital TV scenario, standard ISDB-T. The proposed strategy has five steps: definition of return channels and performance metrics; performance measurements of access technologies in real scenarios; scenario simulation; apply correlation techniques to generate the weight vector; and application of analytical decision making for choosing the best technology to be implemented in a given scenario. As main result a generic and flexible model is presented, validated with a case study for ordering the preference of the evaluated technologies.porAcesso AbertoTv digital interativaProvedor de serviçoCanal de retornoTomada de decisãoReturn channelInterative digital TVTeseCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOES::SISTEMAS DE TELECOMUNICACOESDecision makingService provider
