摘要:
A stream on a recording medium is divided into parts, and is subjected to rearrangement editing while the compatibility with a playback-only device is maintained.By adopting a division processing procedure of a play item, rearrangement processing of a stream for each chapter is achieved. In a product specification, a plurality of real play lists are put together into a series of chapter groups to be presented to the user, and thus there are cases where rearrangement of chapters are closed in the same play list, and cases where the rearrangement extends over a plurality of play lists. Moreover, rearrangement editing, which moves a chapter between real play lists, between virtual play lists, and further from a real play list to a virtual play list, is performed.

Apparatus and method for providing thumbnail image data on a mobile terminal are provided. The apparatus and method comprise determining whether an image management mode is selected when the mobile terminal is in a standby mode; analyzing bit streams of a plurality of stored actual images to obtain picture sizes and compression ratios of the actual images upon selection of the image management mode; extracting Discrete Cosine Transform (DCT) coefficients at certain blocks of the bit streams of the actual images based on the obtained picture sizes and compression ratios; and partially decoding the extracted DCT coefficients, reducing the partially decoded DCT coefficients at a predetermined rate for generating thumbnail images of the plurality of actual images and displaying the generated thumbnail images.

A reproduction apparatus reproduces view data including several tracks within a range of reproduction processing capacity. A reproduction apparatus for reproducing data from a recording medium having several tracks each used for recording image data and one or more pieces of edit data includes an input unit for inputting the data from the recording medium, an analysis unit for identifying the recording track type of the input data, a storage unit for storing a priority-level assignment table associating the track types with priority levels for a decoding process, and for storing a predetermined threshold value serving as a border between the priority levels for data to be reproduced and the priority levels for data not to be reproduced, a plurality of decode units each used for decoding a different type of data, and a priority-level determination unit for determining whether the input data is to be decoded based on the track type identified by the analysis unit, the priority level assigned to the input data and the threshold value, and for outputting the input data to one of the decode units selected in accordance with the type of the input data when decoding the input data.
摘要:
An information signal processing apparatus according to the present invention is arranged to receive, as an input, an information signal to temporarily store therein the input information signal and to temporarily store therein management information prepared during a recording of the information signal in the recording medium, thereby recording the temporarily stored information signal and management information in the recording medium. Accordingly, it is possible to record an information signal having a large amount of information in the recording medium without lowering a recording speed and it is also possible to easily reduce the size, weight and cost of the apparatus.

In a recording operation, video data is written to a single port memory at a periodic interval, and the video data is read from the memory between points in time when the video data is written. The read video data is recorded on a recording medium. During a reproducing operation, reproduced video data is written in the single port memory, and the reproduced video data is read from the memory at a periodic interval. Further reproduced video data is written to the memory between points in time when the reproduced video data is read. In backward reproduction, reproduced video data is read in an order opposite to that in which it was written.
摘要:
A method and apparatus wherein video images are recorded on a plurality of tracks of a tape such that, for playback in a search mode at a speed higher than the recording speed the displayed image will consist of a plurality of contiguous parts, some of the parts being read out from tracks each having a different frame recorded thereon.
摘要:
A data reproduction apparatus and a data storage medium for synchronously reproducing multiplexed data with video, audio, and superimposed dialogue data compressed at a variable rate and performing various functions. Data are reproduced from the data storage medium using sector numbers, and data for negative sector numbers carried by some sectors are also reproduced. Multiplexing information indicating whether or not image, voice, and superimposed dialogue data is each multiplexed and information for the positions of access points used for data search and random access are stored in the positions represented by these negative sector numbers and reproduced so as to enable multiplexed data with video, audio, and superimposed dialogue data compressed at a variable rate to be synchronously reproduced and various functions to be executed.

摘要:
A video signal transmitting/receiving apparatus for converting video signals into picture data in predetermined block units for transmission to a transmission path in the asynchronous transfer mode in which a first video material formed by the video signals is transmitted to the transmission path, and for receiving picture data inputted in predetermined block units by the asynchronous transfer mode from the transmission path and for converting the received picture data into video signals in which a second video material is formed therefrom. In this apparatus, an approach is employed to record digital video signals onto the prescribed video signal recording medium and thereafter to intermittently reproduce those digital video signals in order to transmit the video signals to a transmission path in the asynchronous transfer mode, or an approach is employed to record data received from the transmission path in the asynchronous transfer mode onto the recording medium, thus allowing digital video signals of a synchronous transfer system to be transmitted to the transmission path in an asynchronous transfer mode such as B-ISDN, etc.
