Abstract: A media center and an audio visual (AV) unit may be remotely synchronized on the same remodulation channel. A system may include a media center connected to an audio visual (AV) unit; and a remote control unit to activate the media center. The remote control unit may receive signals from the media center to indicate a transmission channel for the AV unit, and the remote control unit may send the received signals to the AV unit to independently cause the AV unit to switch to the indicated transmission channel.
Abstract: One aspect of the disclosed technology is a limited social television system that provides a light-weight process that allows multiple audience members to close the loop of interaction and create a compelling feeling of “shared experience” on the part of the response-reviewer.

Abstract: The present invention relates to an interactive medium and a method for managing additional contents synchronously outputted with audio/video (A/V) data in an interactive digital versatile disk (I-DVD). A player in which an interactive disk is seated accesses a server providing the additional contents of the A/V data recorded on the interactive disk before the interactive disk is reproduced, and receives updated information of the additional contents from the server. The player refers to the received updated information and determines whether an arbitrary file contained in an additional content list associated with the A/V data has been updated. The player makes a request for an original file contained in the list or an updated file designated in the updated information, and receives the requested original or updated file. Therefore, the player can always receive additional contents containing the updated file. According to this operation, the server enables the additional contents to be conveniently updated.
