    Abstract: Systems and methods of a media device are operable to perform a channel change operation. An exemplary embodiment receives a first data table from a data table server, wherein the first data table comprises first control information used to perform a channel change operation such that the media device reconfigures itself to change to a new channel from a currently presenting channel or to a new media content event from a currently presenting media content event. The exemplary embodiment later receives a second data table after initiation of the channel change operation, wherein the second data table is broadcast to the media device in one of a plurality of received broadcasting media content streams that has the new media content event, and wherein the second data table comprises second control information that corresponds to at least some of the first control information used to perform the channel change operation.

    Abstract: A method for synchronizing playback of a program including a video and associated first audio at a first electronic device with playback of a second audio associated with the program at a second electronic device that also receives the first audio, the method comprising: decoding, by a first audio decoder in the second electronic device, the first audio, and outputting the decoded first audio; decoding, by a second audio decoder in the second electronic device, the second audio and outputting the decoded second audio for playing back by the second electronic device; receiving a user command to synchronize the playback of the video at the first electronic device and playback of the second audio at the second electronic device; responsive to the user command, the method further comprising capturing, by a capturing device in the second electronic device, the playback of the first audio at the first electronic device; determining, by the second electronic device, an offset between the outputted decoded first audio and the captured first audio; and adjusting outputting of the decoded second audio according to the offset, so that the playback of the first audio at the first electronic device is synchronized with the playback of the second audio at the second electronic device.

    Abstract: A system for making available at an end-user a media file, from a media provider comprising a media file patch related to at least one object, the system comprising: an encoding module at the media provider configured for determining at least one representation which resembles the media file patch, by comparing the media file patch with representations of said at least one object, and for including at least one identification corresponding with said representation in a skeleton file; a storage medium storing a dictionary including the representations of the at least one object at of the end-user and an intermediate node between the media provider and/or the end-user; a decoding module configured for decoding the skeleton file using the identification for looking up the corresponding representation in the dictionary of the storage medium and for rendering the media file patch based on the looked-up corresponding representation.
