In General, When we want to display information from the Arduino, such as a temperature sensor, We usually use a serial Terminal, because of the ease in obtaining this.
Another way to view this, home with something more, It would be with the LCD, but are somewhat expensive.
Then with some research, faced with this site, so you can display information on a TV:
The project and the electronic scheme is very simplistic. Download the compressed file “Ubuntu beta”, copy it to the folder “libraries” the arduino and use the proposed examples. One of them is precisely send terminal commands and display them on a television:
In figures contained in an amendment to the original program, in order to have a “buffer” send text phrases, instead of sending unique characters.

A funny idea (I don't know if one already exists or not) would use a PIC (of the most rascos) to generate your tv signal, something kind of graphic card output to tv to use other MCU's…
This idea of stream with a microcontroller from microchip already exists and is well developed. It is up of the Pic16f84a, one of the most rudimentary and celebrated of the company.
In This “site” There is a lot of information, projects about generating tv signals :
