| 20080199021 | Method and Apparatus For Providing Ip Datacasting Service in Digital Audio Broadcasting System - Provided are a method and apparatus for providing an IP datacasting service in a digital broadcasting system. The method for providing the IP datacasting service in the digital broadcasting system includes: generating service configuration information indicating that the IP datacasting service is provided; packetizing data to be transmitted and generating IP packet data; formatting information related to a configuration of the IP packet data by using a predetermined protocol; and transmitting the service configuration information, the IP packet data, and the information related to the configuration of the IP packet data through separate channels, respectively. Accordingly, various information related to transmitted multimedia data is transmitted together with the multimedia data, so that an IP datacasting function for appropriately processing the multimedia data according to the type of the multimedia data is provided. | 08-21-2008 |
| 20080310744 | METHOD AND APPARATUS FOR INTRAPREDICTION ENCODING/DECODING USING IMAGE INPAINTING - A method and apparatus for intraprediction encoding/decoding is provided. The method includes performing image inpainting based on pixels included in a previously encoded region of a current picture among pixels that are adjacent to a boundary between a current block and the previously encoded region of the current picture in order to predict the current block, and performing prediction encoding on the current block using the prediction result. Thus, a new intraprediction mode in which the current block can be accurately predicted can be provided. | 12-18-2008 |
| 20090045987 | METHOD AND APPARATUS FOR ENCODING/DECODING METADATA - A method for encoding metadata having a plurality of symbols is provided. The encoding method includes: determining an indication of a previously encoded symbol having substantially same symbol data as that of a current symbol that is to be encoded and encoding the current symbol based on the previously encoded symbol. | 02-19-2009 |
| 20090046597 | METHOD AND APPARATUS FOR GENERATING AND ACCESSING METADATA IN MEDIA FILE FORMAT - Provided are a method and apparatus for generating and accessing metadata in a media file format. The method of generating metadata in a media file format includes generating a time-track map composed of a plurality of map nodes that are distinguished according to track and unit time, and generating media objects corresponding to each of the map nodes, in which each of the map nodes includes position information of the corresponding media objects, thereby facilitating real-time reproduction and modification of content. | 02-19-2009 |
| 20090049099 | METHOD AND APPARATUS FOR MANAGING MEDIA FILE - 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. | 02-19-2009 |
| 20090113302 | METHOD OF MANIPULATING MEDIA OBJECT IN MEDIA PLAYER AND APPARATUS THEREFOR - 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. | 04-30-2009 |
| 20090119565 | Data transmitting/receiving system and method thereof - A data transmitter transmitting a data packet containing identifier information including a kind of data, a sequence of data, and/or a packet generating sequence. A receiver extracting a packet number and the identifier information for an error-receipt occurring data packet based upon the identifier information recorded in a header of the packet, generating retransmission control information, such as retransmission times and priority, based on the extracted packet number and the identifier information and transmitting the retransmission control information to the transmitter of the packet. The retransmitting the error-occurring data packet according to the received retransmission control information. The number of retransmissions and the retransmission priority can be varied according to characteristics of the transmitted data, so that retransmissions is suitable for the characteristics of the data and to more stably receive the data that is more influential to the restoration of the data. | 05-07-2009 |
| 20090190657 | FILTERING METHOD FOR REMOVING BLOCK ARTIFACTS AND/OR RINGING NOISE AND APPARATUS THEREFOR - Provided are a filtering method and apparatus for removing blocking artifacts and ringing noise. The filtering method includes transforming video data on a block-by-block basis, and detecting the presence of an edge region in the video data by checking the distribution of values obtained by the transformation. Accordingly, it is possible to completely remove blocking artifacts and/or ringing noise by more effectively detecting the presence of an edge region in video data. | 07-30-2009 |
| 20100074541 | CODING AND DECODING METHOD AND APPARATUS USING PLURAL SCANNING PATTERNS - Provided is a coding and decoding method and apparatus using a plurality of scanning patterns. The method for coding image data includes: (a) obtaining N×M data by firstly source-coding the image data; (b) scanning the N×M data using a predetermined scan pattern selected from a plurality of scan patterns in response to the obtained N×M data; and (c) firstly source-coding the scanned data. Accordingly, coding and decoding image data having various characteristics can be implemented efficiently. Particularly, even for the image data having an interlaced scanned frame format, more efficient coding and decoding can be achieved. | 03-25-2010 |
| 20110058613 | METHOD AND APPARATUS FOR GENERATING BITSTREAM BASED ON SYNTAX ELEMENT - A method and apparatus for generating an optimized bitstream. In the method, a bitstream including first and second processing units is received. The video processing units are encoded to generate syntax data for syntax elements of the video processing units. The syntax data of the video processing units are grouped according to the type of syntax element, and the groups are arranged in a predetermined order to produce the optimized bitstream. | 03-10-2011 |
