Abstract

A control apparatus comprises a digital interface for connecting to an external apparatus; a judging unit adapted to judge whether the external apparatus connected via the digital interface can perform streaming; and a communication unit adapted to issue a request for transferring streaming to the external apparatus if it is judged that the external apparatus can perform streaming, and adapted to issue no request for transferring streaming to the external apparatus if it is judged that the external apparatus cannot perform streaming.

Claims

1. A control apparatus comprising:

a digital interface for connecting to an external apparatus;

a judging unit adapted to judge whether the external apparatus connected via the digital interface can perform streaming; and

a communication unit adapted to issue a request for transferring streaming to the external apparatus if it is judged that the external apparatus can perform streaming, and adapted to issue no request for transferring streaming to the external apparatus if it is judged that the external apparatus cannot perform streaming.

2. The apparatus according to claim 1, wherein the judging unit judges whether the external apparatus connected via the digital interface has a function of issuing a recording request of video data, and

wherein the communication unit issues a transfer request of the video data to the external apparatus if the external apparatus has the function of issuing the recording request, and issues no transfer request of the video data to the external apparatus if the external apparatus does not have the function of issuing the recording request.

3. The apparatus according to claim 2, wherein the judging unit judges whether the function of the external apparatus of issuing the recording request is ON or OFF if the external apparatus has the function of issuing the recording request, and

wherein the communication unit issues the transfer request of the video data to the external apparatus if the function of issuing the recording request is ON, and issues no transfer request of the video data to the external apparatus if the function is OFF.

4. The apparatus according to claim 1, wherein the judging unit judges whether a function of the external apparatus, which is connected via the digital interface, of issuing a recording request of video data is ON or OFF, and

wherein the communication unit issues a transfer request of the video data to the external apparatus if the function of issuing the recording request is ON, and issues no transfer request of the video data to the external apparatus if the function is OFF.

5. The apparatus according to claim 1, wherein the digital interface is a USB interface.

6. The apparatus according to claim 1, wherein the external apparatus is an image capture apparatus.

7. A method for use in a control apparatus which controls an external apparatus, comprising the steps of:

judging whether the external apparatus connected via a digital interface can perform streaming;

issuing a request for transferring streaming to the external apparatus if it is judged that the external apparatus can perform streaming; and

issuing no request for transferring streaming to the external apparatus if it is judged that the external apparatus cannot perform streaming.
