What about a building block (module) for a Digital Terrestrial Receiver standard if it would be of interest. You would need to identify the basic functionality of the Digital TV receiver and then identify its main system blocks. Isolate one block and proceed to form a diagram and then use matlab, Simulink or some sort HDL (Verilog or VHDL) Coding
