Research Groups | Digital TV

The Digital TV Research Center is involved in several layers related to the study and the development of digital television. It acts in the area of source signals encoding (mainly in a H.264 video chip and in software), the transport layer (multiplexer and SI tables), development of interactive applications (mostly Java), interactivity channel, and development of an IPTV set-top box, including the corresponding embedded system.

Research Themes

  • Development of integrated circuits: The objective of the integrated circuits development group is the design and study of special purpose integrated circuits to be used by the industry of digital TV equipment.
  • Multimedia: Problems related to digital convergence (audio, video and data), including the analysis of issues related to the transmission through computer networks, as well as to the development of applications.
  • Computer networks: Research issues ranging from the transmission of information by physical channels to the various protocols and network technologies, including optical and mobile networks. Analysis of alternatives for multimedia communication with multicast and other one-to-many communication alternatives.
