Reproducing device, reproducing method, program, and transmitting device

A reproducing apparatus comprising:

• a memory;
• and
• circuitry coupled to the memory and configured to
• receive content data and caption data, the caption data corresponding to the content data and having elements defined in Extensible Markup Language (XML);
• generate a content video signal based on the content data;
• receive an initial user setting to select at least one of a caption display mode and caption character edge type;
• retain the initial user setting in a non-volatile memory region;
• generate intermediate caption information from the caption data;
• overwrite and update the intermediate caption information based on the retained initial user setting in the non-volatile memory region;
• generate a caption video signal according to the overwritten and updated intermediate caption information;
• superimpose the caption video signal on the content video signal and reproduce the content video signal together with the superimposed caption video signal;
• during reproduction of the content video signal together with the superimposed caption video signal, receive an updated user setting to select at least one of the caption display mode and the caption character edge type;
• retain the updated user setting in a volatile memory region;
• and
• overwrite and update the intermediate caption information based on the updated user setting.
