Method of restoring AV session and a control point for the same
First Claim
Patent Images
1. A method of restoring an AV session, the method comprising:
- collecting, by a control point, AV session information, by periodically requesting the AV session information from a media renderer;
restoring, by the control point, the AV session based on the collected AV session information when an error occurs in the AV session; and
streaming content corresponding to the AV session from a media server to the media renderer during a playback of the content in the media renderer, and performing the collecting of the AV session information from the media renderer while the media renderer plays the content during the playback,wherein the collected AV session information comprises a volume state, a brightness state and a contrast state set within the media renderer during the playback of the content, andduring the restoring, the control point restores a state of the media renderer to a most recent volume state, a most recent brightness state and a most recent contrast state collected prior to the error,wherein the restoring comprises requesting the media renderer, which is identified through the collected AV session information, to play content in the AV session, which is identified through a URI of the content obtained by the collected AV session information, from a content-playing position obtained by the collected AV session information,wherein the error occurs in the. AV session when at least one of an error-event message is received from at least one of the media renderer and the media server, and when a disconnection message is received from at least one of the media renderer and the media server in a state of at least one of the playing of content is not stopped and a request for stopping the playing of content is not input by a user.

1. A method of restoring an AV session, the method comprising:
-
collecting, by a control point, AV session information, by periodically requesting the AV session information from a media renderer; restoring, by the control point, the AV session based on the collected AV session information when an error occurs in the AV session; and streaming content corresponding to the AV session from a media server to the media renderer during a playback of the content in the media renderer, and performing the collecting of the AV session information from the media renderer while the media renderer plays the content during the playback, wherein the collected AV session information comprises a volume state, a brightness state and a contrast state set within the media renderer during the playback of the content, and during the restoring, the control point restores a state of the media renderer to a most recent volume state, a most recent brightness state and a most recent contrast state collected prior to the error, wherein the restoring comprises requesting the media renderer, which is identified through the collected AV session information, to play content in the AV session, which is identified through a URI of the content obtained by the collected AV session information, from a content-playing position obtained by the collected AV session information, wherein the error occurs in the. AV session when at least one of an error-event message is received from at least one of the media renderer and the media server, and when a disconnection message is received from at least one of the media renderer and the media server in a state of at least one of the playing of content is not stopped and a request for stopping the playing of content is not input by a user. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A control point comprising:
-
an information-collecting module that collects AV session information by periodically requesting the AV session information; a restoration module that restores an AV session based on the collected AV session information when an error occurs in the AV session; and a control module that configures a media server and a media renderer to stream content corresponding to the AV session from the media server to a media renderer during a playback of the content in the media renderer, and the information-collecting module collects the AV session information from the media renderer while the media renderer plays the content during the playback, wherein the collected AV session information comprises a volume state, a brightness state and a contrast state set within the media renderer during the playback of the content, and during the restoring, the restoration module restores a state of the media renderer to a most recent volume state, a most recent brightness state and a most recent contrast state collected prior to the error, wherein the restoration module requests the media renderer, which is identified through the collected AV session information, to play content in the AV session, which is identified through a URI of the content obtained by the collected AV session information, from a content-playing position obtained by the collected AV session information, and wherein the error occurs in the AV session when at least one of an error-event message is received from at least one of the media renderer and the media server, and when a disconnection message is received from at least one of the media renderer and the media server in a state of at least one of the playing of content is not stopped and a request for stopping the playing of tent is not input by a user. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
