Abstract

In a case where a communication device receives a playback request for second content while playing back first content, the communication device starts playing back the second content, based on a fact that a communication device identified by identification information about a communication device that has transmitted a playback request for the first content is identical to a communication device identified by identification information about a communication device that has transmitted the playback request for the second content, and continues playing back the first content, based on a fact that the communication devices are different. The communication device starts playing back the second content, based on a fact that a user identified by user identification information about the first content is identical to a user identified by user identification information about the second content, and continues playing back the first content, based on a fact that the users are different.

First claim

What is claimed is:

1 . A communication device comprising:
a first receiving unit configured to receive a playback request for content; a playback unit configured to play back the content based on the playback request received by the first receiving unit; an obtaining unit configured to obtain device identification information for identifying a source device that has transmitted the playback request received by the first receiving unit; and a control unit configured to perform, in a case where the first receiving unit receives a playback request for second content while the playback unit is playing back first content, control to start playing back the second content, based on a fact that a source device identified by first device identification information is identical to a source device identified by second device identification information, the first device identification information identifying a source device that has transmitted a playback request for the first content, the second device identification information identifying a source device that has transmitted the playback request for the second content, and control to continue playing back the first content, based on a fact that the source device identified by the first device identification information is different from the source device identified by the second device identification information.

2 . The communication device according to claim 1 , further comprising a first notifying unit configured to notify, based on a fact that the source device identified by the first device identification information is different from the source device identified by the second device identification information, the source device that has transmitted the playback request for the first content that an interrupt has occurred.

3 . The communication device according to claim 2 , further comprising a second receiving unit configured to receive a response to a notification made by the first notifying unit from the source device that has transmitted the playback request for the first content, wherein
the control unit performs control to start playing back the second content, based on a fact that the source device identified by the first device identification information is different from the source device identified by the second device identification information and that the second receiving unit has received a response indicating permission for the interrupt, and control to continue playing back the first content, based on a fact that the source device identified by the first device identification information is different from the source device identified by the second device identification information and that the second receiving unit has received a response indicating non-permission for the interrupt.

4 . The communication device according to claim 1 , wherein the device identification information obtained by the obtaining unit is a media access control (MAC) address of the source device that has transmitted the playback request received by the first receiving unit.

5 . The communication device according to claim 1 , wherein the device identification information obtained by the obtaining unit is a universally unique identifier (UUID) of the source device that has transmitted the playback request received by the first receiving unit.

6 . The communication device according to claim 1 , wherein the device identification information obtained by the obtaining unit is an Internet protocol (IP) address of the source device that has transmitted the playback request received by the first receiving unit.

7 . The communication device according to claim 1 , wherein in a case where the playback request received by the first receiving unit is a mirroring playback request,
the playback unit plays back, in synchronization with the source device that has transmitted the mirroring playback request, content including at least one of image data which is based on a screen displayed on the source device that has transmitted the mirroring playback request and which has been received from the source device that has transmitted the mirroring playback request, and audio data which is based on audio that is being played back.

8 . The communication device according to claim 1 , wherein in a case where the playback request received by the first receiving unit is a direct streaming playback request,
the playback unit plays back content which is held by the source device that has transmitted the direct streaming playback request and which has been received from the source device that has transmitted the direct streaming playback request.

9 . The communication device according to claim 1 , wherein in a case where the playback request received by the first receiving unit is a content redirection playback request,
the playback unit plays back content received from an external device different from the source device that has transmitted the content redirection playback request, based on related information about the content included in the content redirection playback request.

10 . The communication device according to claim 9 , wherein the related information is a uniform resource identifier (URI) indicating a storage region of the content in the external device.

11 . The communication device according to claim 1 , further comprising a second notifying unit configured to notify, based on a fact that the control unit has performed control to continue playing back the first content, the source device that has transmitted the playback request for the second content of non-permission for playback of the second content.

12 . The communication device according to claim 1 , further comprising a third notifying unit configured to notify, based on a fact that the control unit has performed control to continue playing back the first content, the source device that has transmitted the playback request for the second content of permission for playback of the second content.

13 . The communication device according to claim 1 , wherein the first receiving unit receives the playback request for the content in accordance with a scheme conforming to a Wi-Fi Miracast standard.

14 . A communication device comprising:
a first receiving unit configured to receive a playback request for content; a playback unit configured to play back the content based on the playback request received by the first receiving unit; an obtaining unit configured to obtain user identification information for identifying a user related to the playback request received by the first receiving unit; and a control unit configured to perform, in a case where the first receiving unit receives a playback request for second content while the playback unit is playing back first content, control to start playing back the second content, based on a fact that a user identified by first user identification information is identical to a user identified by second user identification information, the first user identification information identifying a user related to a playback request for the first content, the second user identification information identifying a user related to the playback request for the second content, and control to continue playing back the first content, based on a fact that the user identified by the first user identification information is different from the user identified by the second user identification information.

15 . The communication device according to claim 14 , further comprising a first notifying unit configured to notify, based on a fact that the user identified by the first user identification in
