| Abstract |
The addition of interactive services to Digital Television is the key element to the transition from Analog to Digital Broadcasting. Such services reflect the current wishes and expectations of television viewers from Digital TV. The way to realize this goal is the definition of a return channel using the same medium as the existing broadcasted. In defining a return channel for the Digital Video Broadcasting Terrestrial system, the DVB forum produced DVB-RCT (Digital Video Broadcasting Return Channel Terrestrial), an ETSI standard (EN 301 958) providing specification for interactivity in the VHF/UHF bands. The result is the definition of a high bandwidth Wireless Interactive Terrestrial Digital TV system using a multiple access OFDM arrangement. The next step that must be taken in the direction of DVB-T becoming a bidirectional system is the design of a VLSI solution for the integration of DVB-RCT in a TV set top box. The goal of this thesis is the implementation, as part of a future ASIC, of the stage that constitutes the cornerstone of the DVB-RCT physical layer: the Frame Adaptation unit. First, we present the Physical layer and the system parameters. A careful study of the transmission parameters and the physical layer is necessary in order to comprehend the Frame Adaptation requirements. Then, we define the units functionality and main architecture. The main accomplishment of the thesis is the design specification of the Frame Adaptation unit and its implementation with the creation of a validated synthesizable VHDL model. The delivered model has been integrated in an FPGA platform employed for a successful real time demonstration of the DVB-RCT system.
