    摘要: The DVD Stream Recording standard defines application packets as the logically smallest units created from the input data stream during recording. Usually the conversion from a point on the time axis to a corresponding application packet is realised by using a mapping list available in the navigation data. However, depending on the target time and a Stream Object selected, the match found can vary significantly. The invention allows editing a recorded stream of application packets with higher precision. The stream comprises at least a first application packet having a first arrival time stamp and a subsequent second application packet having a second arrival time stamp. For editing the recorded stream a discrete time is input that is a start time or an end time and has a value between the first arrival time stamp and the second arrival time stamp. The discrete time is mapped onto the first or the second arrival time stamp, and the recorded stream is edited correspondingly.

    摘要: In DVD Stream Recording Stream Object Units are real-time recorded, wherein such fixed-length Stream Object Units serve as a container for Application Packets that have a variable length and carry payload data and an Application Time Stamp, this timestamp enabling proper real-time playback. In case the temporal distance between two succeeding application packets is too big, stuffing data must be inserted into the corresponding Stream Object Units. The real-time stuffing control is performed such that overflow of the input buffer is avoided in case of a specific kind of input signals.

    摘要: DVD Rewritable/Re-recordable discs will be used for recording and playing back digital bitstreams, for example MPEG data packets. To enable proper real-time playback of stored MPEG transport packets, a time information is to be added to every data packet to be recorded. A DVD streamer is connected to the application device via an interface, e.g. IEEE 1394. The interface internally uses timestamps having a special format. According to the invention, such interface-generated timestamps are also used for the DVD stream recording, instead of additionally generated independent streamer-specific timestamps. However, a timestamp format conversion is to be carried out because the DVD Streamer timestamp format is different from the IEEE 1394 timestamp format. For such timestamp format conversion differences between consecutive IEEE 1394 timestamps are determined and are used for calculating the DVD stream recording timestamps.

    摘要: The invention relates to the updating of a local copy of metadata. First change history data of metadata are read from an optical storage medium. Second change history data of the metadata are read from a local storage of an optical storage medium playback and/or recording device. If the first and second change history data are different a change attribute is read a from the optical storage medium and an update operation of the metadata stored in the local storage or an update operation in the optical storage medium is determined depending on the change attribute.

    摘要: Optical storage media often contain data structures for a menu suitable for selection of a title, a chapter, a parameter or others. Such menus usually comprise a number of buttons to be displayed, with each button having a state. Possible states of buttons are “unselected”, “selected” or “activated”. According to the invention, the representation of a menu button may vary, depending on its state. An image or an image sequence, e.g. cartoon, may be associated to a buttons state, providing user animation. Further, a sound or sound sequence, e.g. melody or click, may be associated to a buttons state, and may be played back when the button enters this state. A data structure is disclosed which allows storage of such menu data e.g. on a Blu-ray disc.
