Provided are a method and apparatus for transmitting digital multimedia broadcasting data, and a method and apparatus for receiving digital multimedia broadcasting data. A basic audio signal and a multichannel audio signal are encoded to generate a basic audio stream and a multichannel audio stream, and a first data stream describing property and position data of the basic audio stream and a second data stream describing property and position data of the multichannel audio stream are transmitted as independent streams. According to the performance of the receiving apparatus, an audio signal may be decoded by using just the first data stream only or both the first data stream and the second stream.

Provided is a method of encoding media content and metadata. The method includes generating a scale indicator, which indicates a unit size of information about the media content, in the metadata, and determining data areas in the metadata that have different values based on the generated scale indicator. Accordingly, a range that can be expressed by the data area, that has a limited space in the metadata, can be increased.

Provided are a method and apparatus for displaying content. The method includes receiving changed scene information if scene information containing position information indicating the time at which objects constituting the content are displayed and positions of the objects to be displayed is changed, receiving objects for constituting the content based on the changed scene information and determining whether objects overlapping each other exist among the received objects, and displaying the content after selectively changing positions of the objects according to the determination result.

A method of and apparatus for updating decoding information are provided. A method of transmitting media data includes generating a media stream including one or more media data items, one or more decoding information of the media stream, and information for arranging updating of the decoding information; and transmitting the media stream, the one or more decoding information item of the media stream, and the information for arranging updating of the decoding information, in which the one or more media data items have decoding information that are different from each other. According to the method and apparatus, the amount of data to be processed and the complexity of data processing can be reduced, thereby reducing an encoding time and a media data processing time in a decoder.

Provided is a method for manipulating a media object in a media player and an apparatus using the same. The method includes generating a rendering map for managing a region of a media object in a rendering interface according to time, receiving a user input via the rendering interface; updating the rendering map based on a user input; re-composing a scene based on the updated rendering map, and rendering the media object according to the re-composed scene.
摘要:
A method and apparatus for managing a media file are provided. The method of managing a media file comprising a plurality of media objects comprises correcting at least one media object from among the plurality of the media objects; generating or renewing information relating to unused regions generated in the media file according to the correction; and managing the media file based on the generated or renewed information. Therefore, difficulties in file management occurring due to correction of the media objects are reduced so that the media file can be efficiently managed.

Provided are an apparatus and method for generating personal broadcast content. A user terminal apparatus includes a broadcast reception unit receiving broadcast content through a broadcast network; a communication unit controlling connection with a server which provides an authoring tool for generating personal broadcast content and metadata required to obtain one or more pieces of content through the broadcast network and a bi-directional communication network; a user input unit receiving a user input signal; and a control unit configuring a personal broadcast screen, which contains the content, using the authoring tool and the metadata and generating personal broadcast content in response to the user input signal. When the apparatus and method are used, a user can generate personal broadcast content using content which can be obtained through a bi-directional communication channel and a broadcast channel.
