Abstract: A recording medium includes a program containing video data and/or audio data and navigation information which defines a thumbnail, wherein the thumbnail relates to the program and is reproduceable as moving pictures. The recording medium may include a plurality of programs and the thumbnail may identify or represent one or more of the programs. By assigning a predetermined interval of a bit stream corresponding to a program as a thumbnail, the recording medium having the thumbnail thereon, that can be reproduced as moving pictures, can be obtained.

Abstract: A method of recording and reproducing video data is provided. The method of recording video data in an information storage medium includes the steps of (a) decoding originally encoded video data, (b) re-encoding the decoded video data in a different way to the originally encoded video data, (c) generating video transform information which is to be referred to for decoding the video data into its original state, and (d) recording the generated video transform information and the re encoded video data in the information storage medium. Accordingly, the video data can be properly reproduced even if it is re-encoded in a different way to the originally encoded video data.

Abstract: A data storage medium in which multiple bitstreams are recorded, an apparatus and method for recording the multiple bitstreams, and an apparatus and method for reproducing the multiple bitstreams are provided. The reproducing apparatus includes: a reading unit for reading main data including audio data and/or video data, and reading sub data recorded in a separate bitstream from the main data, which is later reproduced in synchronization with the main data; and a multiplexer for multiplexing the main data and sub data read by the reading unit. Therefore, multiple bitstreams can be read and reproduced at the same time.

Abstract: A method for generating additional information for guaranteeing seamless playback of data streams, a recording medium for storing the information, and recording, editing and/or playback apparatus using the same are provided. The method generates additional information for guaranteeing seamless playback. The method includes a step of generating data stream information for each of two or more data streams, which includes packet data to which information on an arrival time of the respective packet data is added. The data stream information includes seamless playback information, which indicates whether a corresponding data stream is to be seamlessly reproduced after playback of a preceding data stream, and/or seamless time control information for controlling an output time of the corresponding data stream to be seamlessly reproduced.

Abstract: A method of controlling a temporary recording based on a variable temporary record interval, and a broadcast receiving device adopting the same, are provided. The broadcast receiving device includes a broadcast receiving unit which receives a broadcast program; a storage unit which temporarily records the broadcast program being received through the broadcast receiving unit; and a control unit which variably determines a temporary record interval with reference to additional information of the broadcast program currently received through the broadcast receiving unit, and controls the storage unit so that a temporary recording is performed during the determined temporary record interval. Accordingly, even if the currently viewed broadcast program has a long running time, the user can view again the previously viewed part of the broadcast program.
