  • Publication number: 20220191581
    Abstract: Systems and methods are provided herein for scheduling a season recording. A series is provided to a user device, the series having a plurality of sequential seasons, and each season having a plurality of episodes. A request for recording the series is received from the user. In response, a last episode of the series watched by the user is identified. A relevant season of the plurality of seasons is then determined, such that the relevant season precedes another season of the plurality of seasons and includes the last episode watched by the user. Then, episodes of the relevant season that follow the last episode watched by the user are scheduled for recording, such that episodes of a season that precedes the relevant season are not scheduled for recording.

  • Publication number: 20210105537
    Abstract: Systems and methods are provided herein for receiving a request from a user to access a video that is scheduled for transmission, simultaneously to a plurality of users, beginning from a scheduled start time. The request is received after the scheduled start time the transmission is performed by a linear service to which the user subscribes. In response to receiving the request, the systems and methods may generate for display the video to the user, and may receive, during display of the video, a command from the user to start playback of the video over from the beginning. In response to receiving the command, the systems and methods may identify a non-linear service to which the user subscribes that offers a non-linear copy of the video, and may play back the non-linear copy of the video from the beginning.

  • Patent number: 10838379
    Abstract: A controller stores an apparatus-room association table in which an apparatus installed in a home is associated with a room in the home, and stores a room-user association table in which the room in the home is associated with the user. The controller determines whether the user is inside the home, and updates a user status. When the user status changes, the controller determines the apparatus corresponding to the user whose user status has changed, and controls the determined apparatus to execute a predetermined process based on the apparatus-room association table and the room-user association table.
