No. of bitstreams: 1 Dissertacao de Guilherme Daher Ferreira.pdf: 1480938 bytes, checksum: 0a076c807b7bde1fd9d7ef383e8184ac (MD5) Previous issue date: 2010-08-28 / As with all major digital terrestrial TV systems, the Brazilian middleware called Ginga, supports both declarative applications (through its presentation declarative environment Ginga-NCL) and procedural applications (through its execution procedural environment Ginga-J). Unlike the fixtures, the Brazilian standardization provides that for the portable devices, only the environment Ginga-NCL is required. Today in Brazil there are some portable devices that allow the reception of digital TV signal. However, a minority of these devices are equipped with the middleware adopted by the Brazilian System of Digital Television - SBTVD. Known, although there is no device capable of running applications to digital television, using the AndroidTMplatform operating system, like, there is also no open-source middleware implementation, available to the scientific community, capable of playing, in Brazilian standard, digital TV on portable devices. This paper describes the process used for implementation of Ginga-NCL, as well as details of the encoding for portable devices based on AndroidTMoperating system. As a means to validate the implementation, experiments were conducted to analyze the performance of applications NCL and resource usage of the handheld device / Hoje existem no Brasil alguns dispositivos portáteis que permitem a recepção do sinal de TV digital. No entanto, uma minoria destes aparelhos estão equipados com o middleware adotado pelo Sistema Brasileiro de Televisão Digital - SBTVD. Sabidamente, ainda não existe nenhum dispositivo capaz de executar aplicaçãoes para televisão digital utilizando a plataforma AndroidTMcomo sistema operacional. N ao existe também nenhuma implementação aberta disponível para comunidade científica, de um middleware capaz de reproduzir aplicações, no padrão brasileiro, para televisão digital em dispositivos portáteis. Este trabalho descreve o processo utilizado para implementação do Ginga-NCL, bem como detalhes da codificação, para dispositivos portáteis baseados no sistema operacional AndroidTM. Como meio de validar a implementação, foram conduzidos experimentos para analisar a execuçãao de aplicações NCL, bem como o uso de recursos do dispositivo portátil
