Abstract:
PURPOSE: A recorder, in which multi-stream is recorded, a device and a method for recording multi-stream, and a device and a method for producing multi-stream are provided to easily replace and correct various data, and to read a number of bit streams at the same time. CONSTITUTION: A recorder, in which multi-stream is recorded, includes main data, sub-data, and navigation information. The main data contains audio data and/or video data. The sub-data is recorded bit stream different from the main data, and synchronizes and is produced with the main data. The navigation information define correlationship between the main data and the sub-data to synchronize the main data and the sub-data.

PURPOSE: A recording medium storing digital data, a method and a system for reproducing the digital data are provided to record and reproduce digital data having a data structure that is interpreted and presented by a digital TV or HDTV. CONSTITUTION: A recording medium(10) records menu data(100) and main data(400). The menu data displays at least one menu. The main data includes at least one of audio data and video data and at least one file that is reproduced when a predetermined menu is selected. A digital data reproducing system includes a data reading unit for reading menu data recorded in a markup language and a main data having at least one file linked with a selected menu and called in its file name, a markup language interpretation engine for interpreting the read menu data to display the menu data in accordance with the grammar of the markup language, and a converter for converting the menu data into a reproduced signal and converting the file into a reproduced signal.
Abstract:
PURPOSE: A signal recording/reproducing device is provided to include a supplementary storage medium to overcome limitations of a storage capacity of a main storage medium, and to consecutively reproduce data stored in the supplementary storage medium and data stored in the main storage medium, thereby recording the data consecutively and reproducing the data consecutively recorded on the supplementary storage medium automatically. CONSTITUTION: When remaining capacities of a main storage medium(222) are smaller than capacities of data to be recorded, a supplementary storage(230) stores the rest data to be recorded on a supplementary storage medium(232). A consecutive reproduction controller(240) decides whether to consecutively reproduce data stored in the main storage medium and the data stored in the supplementary medium, and controls a reproduction operation according to a decided result. The consecutive reproduction controller reads an index stored with data in a final data recording region of the main storage medium, and decides whether the read data is a portion of consecutive data, to control whether to consecutively reproduce the data stored in the supplementary storage medium during reproduction.
Abstract:
PURPOSE: A data recording/reproducing device is provided to convert a bit rate of data of a large-capacity recording medium according to a capacity of a storage medium for backing up the data, thereby storing the data in one storage medium as having a maximum resolution. CONSTITUTION: A resolution setup block(220) stores all data to be backed up in the second recording medium(210) if a storage capacity of the second storage medium is smaller than a capacity of the data. The resolution setup block calculates a bit rate to maintain a maximum resolution. If the storage capacity of the second storage medium is equal to or bigger than the capacity of the data to be backed up, the resolution setup block maintains the bit rate without converting the bit rate. The resolution setup block sets a bit rate selected by a user to a conversion bit rate of the backup data. A transcoder(230) converts a bit rate of data stored in the first storage medium(200) according to the bit rate decided from the resolution setup block, and backs up the converted data in the second storage medium.
Abstract:
PURPOSE: An optical recording/reproducing system is provided to allocate a channel identification code to a sub audio data stream contained in each audio data stream or select an audio channel. CONSTITUTION: A pick-up unit(140) picks up an optical signal from a disc, and an RF amplifier(130) converts the optical signal into an electric signal and extracts a servo signal and modulated data from the electric signal. A digital signal processor(120) demodulates the modulated data to output a compressed A/V data stream. A servo unit(150) receives information required for servo control from the RF amplifier to perform servo control. An AV codec(110) decodes the compressed A/V data stream to output an A/V data stream including a plurality of audio data streams. A key input unit(170) inputs keys for switching recording/reproducing of program having sub audio data streams in/from the disc. A system controller(160) performs user interface, and controls the pick-up unit, RF amplifier, digital signal processor, servo unit and AV codec.
Abstract:
PURPOSE: A method and an apparatus for measuring and displaying recordable capacity/time of a recording medium are provided to suggest recordable capacity or time with an effectiveness by considering a temporary removing interval. CONSTITUTION: A disk is inserted(S101) and a kind of a disk is discriminated(S102). It is confirmed whether a file system exists(S103). It is checked whether a recognition of a file system is possible(S104) and a file system is read(S105). Detecting data are checked to check a capacity of a temporarily removed part(S106). The recognition of detecting data is determined to be possible(S107) and detecting data are read(S108). A recordable capacity is computed(S109) and a recordable time is displayed(S110).
Abstract:
PURPOSE: A recording medium, method for producing and replaying scene conversion point information store a scene conversion point information according to an attribute variation of A/V(audio/video) data. CONSTITUTION: A controller(202) generates a scene conversion point information by tracking an attribute variation of A/V data, and searches a desired position in accordance with a search command at high speed. An A/V format unit(204) analyzes contents of an input A/V data, and sorts it by the minimum recording unit block in accordance with a predetermined criterion. A navigation data generator(206) reanalyzes the minimum recording unit block analyzed in the A/V format unit, and provides a time information required for the replaying of the corresponding unit block and a block size information occupied by the corresponding unit block by one navigation data unit, to a recording controller(208). The recording controller records a recording data provided from the A/V format unit and a navigation data provided from the navigation data generator on a disk(210). A replaying controller(212) reads the A/V data recorded on the desired position of the disk by using the scene conversion point information. An A/V deformat unit(214) deformats the A/V data formatted by a predetermined disk format provided from the replaying controller, and outputs the deformatted A/V data.
Abstract:
PURPOSE: A thumbnail picture writing method for a menu screen and disk recording media thereof is provided, which has a high correlation with the content of a program which a thumbnail picture is an object of a subject expression. CONSTITUTION: A thumbnail picture writing method for a menu screen comprises the steps of: extracting one frame picture included in a moving picture program when a thumbnail picture(14) expresses the subject of the moving picture program; and extracting a picture included in a still picture program when a thumbnail picture(12) expresses the subject of the still picture program, wherein the thumbnail picture is selected from a thumbnail file having a plurality of thumbnail picture to write and the thumbnail picture is extracted from an intra picture when the moving picture program is MPEG. Thereby, the thumbnail picture having a high correlation with the content of a program is written.
