Abstract: A recording medium, method, and apparatus for reproducing text subtitle streams are disclosed. A buffer initially preloads a text subtitle stream including a dialog style segment defining a group of region styles and first and second dialog presentation segments. A text subtitle decoder initially presents a first region of dialog text included in the first dialog presentation segment in a graphics plane and reads a continuous presentation flag included in the second dialog presentation segment, which includes a second region of dialog text. The text subtitle decoder presents the second region of dialog text by preserving the presentation of the first region of dialog text in the graphics plane if the continuous segment indicates that continuous presentation is required between the first and second regions of the dialog text.

Abstract: An unbroadcast program is recommended to a user. A server is supplied with degree of preference data as indices of the taste of users for programs from user terminals, and calculates, based on this, correlations of the preference tendencies for the programs of other users using a service. The user terminal displays an electronic program table transmitted from the server, and when a reservation to view or record is input from the user, reservation information is transmitted to the server. The server calculates predicted values of degrees of preference of the respective users for programs to be broadcast in the future on the basis of the correlations of the degrees of preference and the reservation information, and transmits them to the respective user terminals. The user terminal refers to the degree of preference predicted values of the broadcast scheduled programs, and prepares a list of programs to be recommended to the user.

Abstract: An after recording method comprising a first step of reading the original data including at least a video bit stream from a digital recording medium (1), a second step of decoding the original data, a third step of encoding audio data in synchronism with the decoding of the original data thereby to form a new audio bit stream, and a fourth step of writing the new audio bit stream in an area of the digital recording medium 1 corresponding to a time point substantially equal to the recording area of the original data. The sound after-recorded can be easily reproduced in accurate temporal agreement with the original image.

The method of creating a file of the recording medium includes forming a PlayList file including playback control information of a set of recorded data, forming an object file including an execute command of the PlayList file, and forming an index file including a set of Normal Title information designating a specific object within the object file, and a set of auxiliary Title information designating a random point of data being reproduced by the Normal Title information.

Abstract: A characteristic point detection circuit detects a characteristic point from a base band video signal and generates a characteristic point file. A compressed video signal received from the digital satellite broadcast is supplied to a multiplexing circuit as it is in the form of a bit stream. The multiplexing circuit multiplexes the compressed video signal and characteristic point file. A control circuit obtains the characteristic point file from an optical disc during reproduction, and controls reproduction of the compressed video signal. As described herein above, the supplied compressed video signal is recorded in a recording medium without deterioration of the image quality, and the recorded video signal accepts random access.

Abstract: Subservive data has been incorporated in the content of an optical disc, such as a DVD, to prevent copying of the disc. To defeat such copy protection, devices to copy optical discs are now being controlled to only copy data referred to by selected program paths. Accordingly, it is proposed to provide copy protection for optical discs by introducing errors into redundant control data to frustrate access to content on the disc. For example, the errors may be inconsistencies in a Video Manage Information Table (VMGI) or in a Video Title Set Information Table (VTSI).

Abstract: During reception of data broadcast, the control information is created by a control information creator for storage into a first storage. During normal reproduction of the data content stored in the first storage, the data content of the data broadcast being reproduced and the control information are stored in a second storage. During special reproduction of the data content stored in the first storage or after the special reproduction is stopped, the control information stored in the second storage is compared with the control information read out from the first storage during the special reproduction or after the special reproduction is stopped. When the control information stored in the second storage and the control information read out from the first storage coincide with each other, the data broadcast continues to be reproduced using the data content stored in the second storage.

Abstract: When a signal path in a signal outputting device is changed, the signal outputting device indicates signal path change information representing the change in the signal path to a signal inputting device. Based on the signal path change information, the signal inputting device adaptively changes a signal path between the signal outputting device and the signal inputting device. The signal inputting device can know the signal path in the signal outputting device easier than heretofore, and can simply change the signal path between the signal outputting device and the signal inputting device.

Abstract: The process is characterized in that it comprises: a step of reading tags recorded together with the packets, these tags defining the instants of arrival of the data packets to be recorded, on the basis of a tagging clock (8), a step of comparing the tags with values counted (9) on the basis of a transfer clock (8) for determining the instants of transfer on the bus of the data read from the record carrier, the frequencies of operation of the said tagging and transfer clocks being such that the maximum deviation between these frequencies, added to the maximum drift of the MPEG system clock, is, in proportion to the nominal values, of the order of or less than the drift of the system clock specified in the standard. Application to the storage of MPEG data.

Abstract: A PVR (A) includes an output (70) wherein a TV channel selected for viewing is output, and a storage device (20) that selectively stores a channel indicator (24) therein. A user interface (60) provides means for selectively loading the storage device (20) with a desired channel indicator (24), and means for selecting a TV channel to be sent to the output (70). A buffer (82) is also included. The buffer (82) automatically records the TV channel output for viewing if the storage device (20) has no channel indicator (20) stored therein, and automatically records that TV channel indicated by the channel indicator (24) when one is stored in the storage device (20) even when the TV channel output for viewing is selected to be different from the TV channel indicated by the channel indicator (24).

Abstract: A DVD recorder is provided which includes an NTSC decoder (15) for converting an NTSC-based TV signal into an ITU-R BT. 601-based video signal, an MPEG encoder (17) for encoding the ITU-R BT. 601-based video signal into an MPEG-2 data stream, a driver (23) for recording the MPEG-2-based data stream to a DVD disk, and a VBI slice circuit (24) for detecting VBI from the TV signal. When the V timing of an input signal is asynchronous with that of recording signal, the MPEG encoder (17) inserts null data as blanking data into an arbitrary frame if a frame repeat has occurred or deletes null data from blanking data from an arbitrary frame if a frame skip has occurred.

Abstract: A method and an apparatus for processing a motion picture expert group (MPEG) video, used in a video reproduction apparatus, can prevent a non-reference picture displaying error due to the non-reference picture decoding not completed in time. The apparatus includes a video decoder for generating a non-reference picture on a macroblock-by-macroblock basis by referring to a reference picture; a displaying unit for displaying the non-reference picture on the macroblock-by-macroblock basis. The displaying unit further detects whether decoding of a next macroblock of the non-reference picture is completed when displaying a current macroblock. If decoding of the next macroblock is completed, the displaying unit displays the next macroblock of the non-reference picture. If decoding of the next macroblock is not completed, and the displaying unit displays the corresponding macroblock of the reference picture.
