Apparatuses, methods and systems are provided for controlling volume of a media system. A remote control is configured to control volume of a media unit and an external device simultaneously or consecutively.

Remote control apparatus, method and multimedia system for volume control

A method of performing trick play on a scrambled data stream, the method comprising: extracting position information corresponding to scrambling information from an input scrambled transport stream; demultiplexing a transport stream of a predetermined position according to the stored position information of the scrambling information and extracting the scrambling information and a scrambled data stream pertaining to the scrambling information; descrambling the extracted scrambled data stream by using the extracted scrambling information; and decoding a reference picture based on the position information.

Method and apparatus for performing trick play on scrambled data stream

Provided are a method and apparatus for reproducing a digital broadcast having different compression formats and a method of recording the digital broadcast so that the digital broadcast may be consistently stored and reproduced regardless of a compression format of the digital broadcast. The method of reproducing a digital broadcast includes receiving a transport stream of the digital broadcast which is provided in a compression format; extracting an original stream of a desired program by demultiplexing the transport stream and extracting metadata from the original stream for reproducing or performing trick-play functions on the original stream; separately storing the original stream and the metadata; and decoding the original stream in accordance with the compression format and displaying the original stream. The method and apparatus allows a user to consistently perform functions on the digital broadcast regardless of a compression format of the digital broadcast.

Method and apparatus for reproducing digital broadcast and method of recording digital broadcast

A system for storing video data may include at least one file. The at least one file may include a data cluster including a plurality of data blocks, each data block storing at least some of the video data, and/or a plurality of first pointers sequentially arranged and respectively indicating the plurality of data blocks. The at least one file may be used for time-shifting and recording functions. If the at least one file is used for the time-shifting function, the system may delete contents of the first pointers in a circular manner so that the system sequentially deletes the contents of at least some of the first pointers and/or if the system sequentially deletes the contents of a first pointer that is located last in the arrangement, the next first pointer whose contents are to be sequentially deleted is a first pointer that is located first in the arrangement.
