Abstract:
본 발명은 디지털 데이터의 기록 및 재생 분야에 관한 것이다. 복수개의 디지털 A/V 프로그램에 대한 동시 녹화 및/또는 재생을 위한 장치 및 방법은 오디오 및 비디오 정보를 디지털 데이터 열의 형태로 광 디스크와 같은 기록 매체에 저장할 때 2채널 이상의 다중 프로그램을 하나의 데이터 열로 압축하여 저장한 후 재생 시에 사용자의 조작에 의해 하나의 데이터 열로 기록된 복수개의 프로그램의 일부 혹은 전체를 선택하여 재생시킨다. 본 발명에 따르면, 단일 채널용 디지털 A/V 녹화 및 재생 장치에 값싼 추가 비용으로 다채널 동시 녹화 및 재생 기능을 구현할 수 있는 효과가 있다.
Abstract:
PURPOSE: A digital data regeneration method and a system thereof are provided to regenerate data smoothly though there occurs an error at a time stamp displaying a regeneration time of packet data. CONSTITUTION: The system comprises a time stamp controller(120), a data decoder(150), and a front end controller(130). The time stamp controller(120) checks whether a time stamp value of a current packet is effective in a case that the current packet is included in a data error area, outputs the current packet according to the time stamp value if the time stamp value is effective, and outputs the current packet according to an estimated time stamp value if not effective. The data decoder(150) decodes the received packet and regenerates the data included in the packet. The front end controller(130) corrects the error in the data extracted from data storage according to an error correction symbol and transmits the corrected data to the time stamp controller.
Abstract:
PURPOSE: Storing method and equipment for virtual deleting data is provided to subdue previous size of file allocation information depending on not the size of a file but degree of distribution of file and increase the size of file allocation information for overcoming some problem in interruption process. CONSTITUTION: The storing method and equipment for virtual deleting data comprises the first region having interruption group information, the second region grouping from interruption data to maximum numbers to provide supervising information of video map and audio map effectively and enable reduction of file allocation information and save more available place.
Abstract:
PURPOSE: A recordable media for storing virtual deletion information for still pictures is provided to delete original audio and secondary audio data corresponding to the still pictures, to secure a free area for recording new data, to edit and display not only the original audio but also the secondary audio data in a still picture unit, and to effectively manage by having video map and/or audio map information of the still picture information. CONSTITUTION: A recordable media for storing virtual deletion information for still pictures includes a number of still pictures, first virtual deletion information(303) informing whether or not it is possible that the corresponding still picture of the still pictures is produced now, and still picture group information for dividing the still pictures as groups.
Abstract:
PURPOSE: A recordable media for storing virtual deletion information for still picture is provided to prevent a rapid increase of file area information by preventing dispersion of a recording area to the utmost without producing virtually deleted still picture when a part of data file is deleted by a user's demand. CONSTITUTION: A recordable media for storing virtual deletion information for still picture includes a first area, and a second area. The first area has a number of still picture data. The second area stores at least one or more of still picture group information(303) to manage the still picture data groups. The still picture group information contains at least one or more still picture information having first virtual deletion information of the still pictures.
Abstract:
PURPOSE: A storage medium storing catalog information, a system and a method for reproducing the catalog information are provided to automatically access the position of a catalog using real-time reproduction information extracted from audio data to reproduce the catalog information while reproducing the audio data stored in a DVD disc. CONSTITUTION: A storage medium stores audio data and catalog information related with the audio data. The storage medium includes an audio area(130) storing the audio data and a video information area(120) storing the catalog information. The audio area includes an audio management region(131) having management information about the audio data, and a plurality of audio title sets(132,133,134) recording the audio data. The video information area includes a video management region(121) having management information about the catalog information, and video title sets(122,123,124) recording at least one title catalog of the catalog information with respect to each item of the audio data.
Abstract:
PURPOSE: A recording medium storing information for still images is provided to record a still image with large capacity, original audio and secondary audio data added to the still image using minimum amount of information data. CONSTITUTION: A recording medium includes the first region having a plurality of still image data items, the second region having a plurality of additional audio data items added to the still image data items, and the third region having information that indicates a connection relationship between the still images of the first region and the additional audio data items of the second region. The first, second and third regions exist in files. The first and second regions exist in one file. The information of the third region includes still image group information that groups the plurality of still images and manages the grouped still images, and additional audio group information that groups the additional audio data items and manages the grouped audio data items.

Abstract:
PURPOSE: A method for selecting audio channels is provided to trace an input of audio selection by a user, though a program or an audio data stream is switched in an A/V(Audio-Visual) apparatus that regenerates a plurality of audio streams, so as to select a same type of audio channels. CONSTITUTION: A plurality of programs are included. One program includes at least two types audio data streams. Each audio data stream includes at least two sub audio data streams having a series of not-duplicated ID codes according to a predetermined priority. If a program is switched to another program, whether a sub audio data stream having a channel ID code identical to a channel ID code allocated to a sub audio data stream of the program before switching exists in the switched program is searched. If so, the sub audio data stream having the identical channel ID code is selected in the switched program. And if not, a sub audio data stream having a highest priority of channel ID code is selected in another program.
