7. A video signal receiving apparatus comprising: circuitry configured to receive, from a video signal generating apparatus, a video signal having text data inserted within, the video signal generating apparatus external to said video signal receiving apparatus; extract said text data from said received video signal, the extracted text data representative of an operation corresponding to a selected option on the video signal generating apparatus from a plurality of options, each option corresponding to a different operation to be performed on the video signal receiving apparatus; and interpret, as the selected operation to be performed on said video signal by the video signal receiving apparatus, said text data extracted from the video signal; wherein said video signal receiving apparatus automatically performs the selected operation corresponding to the selected option represented in said text data, and the video signal receiving apparatus performs the selected operation at a point in time in the video signal from which the inserted text corresponding to the selected operation was extracted.
13. The video signal receiving apparatus according to claim 7 , wherein the circuitry is further configured to generate onscreen data; and superimpose said generated onscreen data onto said received video signal, the circuitry is further configured to interpret the extracted text data as an instruction to superimpose said text data onto an image, and the circuitry is further configured to generate, as said onscreen data, the extracted text data.
