Abstract

A signal output apparatus is provided comprising an input unit configured to receive a main data and a notice of the presence of any further information related to the main data, a notifying unit configured to notify the presence of the related information in response to the notice received from the input unit, an acquiring unit configured to acquire the related information in response to the notice received from the input unit, and an output unit configured to multiplex and output the related information acquired by the acquiring unit with the main data received by the input unit.

Claims

1. A signal output apparatus comprising:

an input unit configured to receive a main data and a notice of the presence of any further information related to the main data;

a notifying unit configured to notify the presence of the related information in response to the notice received from the input unit;

an acquiring unit configured to acquire the related information in response to the notice received from the input unit; and

an output unit configured to multiplex and output the related information acquired by the acquiring unit with the main data received by the input unit.

2. A signal output apparatus according to claim 1, wherein

the notifying unit is configured to notify a location from which the related information is acquired and which is contained in the notice.

3. A signal output apparatus according to claim 1, wherein

the notifying unit is configured to notify the action of the acquiring unit for acquiring the related information with time.

4. A signal output apparatus according to claim 1, wherein

the notifying unit is configured to output from the output unit the information to be notified.

5. A signal output apparatus according to claim 1, wherein

the acquiring unit is configured to acquire the related information from the location of the related information contained in the notice.

6. A signal output apparatus according to claim 1, wherein

the output unit is configured to predetermine the setting of priority for desirably selecting between the continuation of outputting the main data and the canceling of outputting the main data during the action of the acquiring unit for acquiring the related information.

7. A signal output method comprising:

an input step of receiving a main data and a notice of the presence of any further information related to the main data;

a notifying step of notifying the presence of the related information in response to the notice received at the input step;

an acquiring step of acquiring the related information in response to the notice received at the input step; and

an output step of multiplexing and outputting the related information acquired at the acquiring step with the main data received at the input step.

8. A signal output method according to claim 7, wherein

the output step is configured to predetermine the setting of priority for desirably selecting between a step of continuing the action of outputting the main data and a step of canceling the action of outputting the main data during the action of the acquiring step for acquiring the related information.
