Abstract

There is provided an apparatus and method to control reproduction of content recorded to a recording medium; control reading, from the recording medium, first content information indicating whether an initial output mode at a start of reproduction is 4K or 2K; and output a notification based on the initial output mode at start of reproduction indicated by the first content information.

Claims

1. An information processing system comprising:

circuitry configured to

control reproduction of content recorded to a recording medium;

control reading, from the recording medium, first content information indicating whether an initial output mode at a start of reproduction is 4K or 2K; and

output a notification based on the initial output mode at start of reproduction indicated by the first content information.

2. The information processing system of claim 1, wherein the circuitry is configured to:

identify the initial output mode as 4K when the first content information indicates an initial output mode of 4K; and

identify the initial output mode as 2K when the first content information indicates an initial output mode of 2K.

3. The information processing system of claim 1, wherein the circuitry is configured to:

control reading second content information, the second content information indicating whether 4K content is recorded to the recording medium; and

output the notification based on the second content information.

4The. The information processing system of claim 3, wherein the circuitry is configured to:

identify whether the display device is 4K compatible; and

select a message to be displayed by the display device as the notification based on the second content information and a result of the identifying.

5. The information processing system of claim 4, wherein the circuitry is configured to:

acquire 4K compatibility information from the display device indicating whether the display device is 4K compatible;

store the 4K compatibility information; and

identify whether the display device is 4K compatible based on the stored 4K compatibility information.

6. An information processing system comprising:

circuitry configured to

control reproduction of content stored to a recording medium;

acquire, from a display device, 4K compatibility information indicating whether the display device is 4K compatible;

output a notification to be displayed by the display device based on the 4K compatibility information; and

control changing an output setting for the display device according to the 4K compatibility information.

7. The information processing system of claim 6, wherein the circuitry is configured to store the 4K compatibility information in a register that stores a reproduction control parameter.

8. The information processing system of claim 6, wherein the circuitry is configured to:

control reading, from the recording medium, first content information indicating whether an initial output mode at a start of reproduction is 4K or 2K; and

control an output setting for the display device based on the 4K compatibility information and the initial output mode indicated by the first content information.

9. The information processing system of claim 6, the circuitry is configured to:

control reading, from the recording medium, second content information indicating whether 4K content is recorded to the recording medium; and

output the notification based on a setting of the second content information and the 4K compatibility information.

10. An information processing system comprising:

circuitry configured to

control reproduction of content stored to a recording medium;

acquire, from the recording medium, down-conversion allowance information indicating whether to allow down-conversion processing on the content; and

determine whether to perform a process of down-converting content, which is output to the display device, according to the down-conversion allowance information.

11. The information processing system of claim 10, wherein the circuitry is configured to:

identify whether the display device is 4K compatible; and

determine whether to perform the process of down-converting the content output to the display device according based on the down-conversion allowance information and a result of the identifying.

12. An information recording medium on which is recorded at least one of 4K content and 2K content and content information indicating whether an output at start of reproduction is 4K or 2K.

13. An information recording medium on which is recorded at least one of 4K content and 2K content and content information indicating whether 4K content is recorded to the information recording medium.

14. An information recording medium on which is recorded at least one of 4K content and 2K content and down-conversion allowance information indicating whether to allow down-conversion display processing that serves as reproduction control information regarding 4K content recorded to the information recording medium.

15. An information processing method executed by an information processing system, the method comprising:

reading first content information recorded to a recording medium, the first information indicating whether an initial output mode at start of reproduction is 4K or 2K; and

controlling a data output setting of a display device based on the initial output mode indicated by the first content information.

16. An information processing method executed by an information processing system, the method comprising:
