Abstract: Provided is a mobile set-top box. In the mobile set-top box, a demultiplexer processor separates first metadata from a transport stream corresponding to a broadcasting stream of which a destination is the mobile set-top box, and separates second metadata being transmitted via another channel, among a plurality of transport streams. A metadata processor unifies the first metadata and the second metadata and the image data transcoder processor transcodes image data included in the transport stream of the broadcasting stream into image data decodable by a user terminal. The metadata unified by the metadata processor and the transcoded image data are multiplexed by the multiplexer and then are transmitted to the user terminal. The mobile set-top box provides an Internet protocol television (IPTV) service to portable terminals of passengers boarding in a moving transportation means such as a bus, a train, and a ship.

Abstract: Provided is a structure for reducing an acoustic load. The structure includes a tape structure. The tape structure includes an attachment part configured to be attached to a substrate, and an off-position part spaced apart from the substrate and having at least one ventilation hole. Therefore, owing to the resilience of the attachment part and shock-absorbing ability of an air layer formed between the off-position part and the substrate, an acoustic load can be reduced. In addition, since air can flow through the ventilation hole, the attachment part of the tape structure may be not separated by variations of air pressure.

Abstract: In a satellite communication system having a long round-trip delay time, a user terminal reports initial buffer status information when the communication between the satellite and the use terminal started. When a trigger, a timer or padding requiring buffer status information report is generated, the user terminal checks whether there are data to be re-transmitted due to transmission failure from the previous BSR. When transmission-failed data exists, the user terminal sets buffer status amount, which is reported through BSR, as a value that is obtained by adding the amount of transmission-failed data to the amount of newly added after previous report. When there are no transmission-failed data, the user terminal reports BSR which is set as the amount of newly added data to the buffer after previous report. For discriminating entire buffer status reporting and the increased amount of data reporting, the reserved index of a header file is used.
