Reproducing device, reproducing method, program, and transmitting device

1. 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.

2. The reproducing apparatus according to claim 1 , wherein the circuitry is configured to overwrite and update the intermediate caption information on a basis of the retained initial user setting in the nonvolatile memory region before reproduction of the content data.

3. The reproducing apparatus according to claim 1 , wherein the circuitry is configured to overwrite and update the intermediate caption information on a basis of the retained updated user setting in the volatile memory region during the reproduction of the content video signal together with the superimposed caption video signal.

4. The reproducing apparatus according to claim 1 , wherein the circuitry is configured to overwrite and update the intermediate caption information on a basis of the retained initial user setting in the nonvolatile memory region before reproduction of the content data, and overwrite and update the intermediate caption information on a basis of the retained updated user setting in the volatile memory region during the reproduction of the content video signal together with the superimposed caption video signal.

5. The reproducing apparatus according to claim 1 , wherein the circuitry is configured to receive a user setting to select a roll-up mode, a paint-on mode, or a pop-on mode as an option for the caption display mode.

6. The reproducing apparatus according to claim 5 , wherein the circuitry is further configured to receive a user setting to specify a drawing rate when the roll-up mode or the paint-on mode is selected as the caption display mode.

7. The reproducing apparatus according to claim 1 , wherein the circuitry is configured to receive a user setting to select a right drop shadow edge, a raised edge, a depressed edge, or a uniform edge as an option for the caption character edge type.

8. The reproducing apparatus according to claim 1 , wherein the received caption data is in an extended Society of Motion Picture and Television Engineers Timed Text (SMPTE-TT) format defining the at least one of a caption display mode and caption character edge type.
