Abstract:
It is desired to link photo data and video data taken by a digital camcorder. Therefore, there is provided a device and method for linking multimedia data, wherein linking information is formed on the basis of first and/or second multimedia data. The linking information is stored on a recording medium together with the first multimedia data. The second multimedia data may be stored together with respective linking information to the first multimedia data on a second recording medium. Thus, a camera-man while recording is able to set up logo or index pictures for a video film.
Abstract:
Several data streams contain video, audio and/or other data. Some of the data streams are pre-recorded in a multiplex on a storage medium while other data streams are located out of the data stream multiplex on the storage medium. The data streams are synchronized using a navigation file (List_of_PlayItems), which comprises descriptors (PlayItems, SubPlayItems) pointing to parts of said data streams, wherein said descriptors define the arrangement in time for said data streams by means of data sub stream paths.
Abstract:
The invention relates to a method of editing a data stream, the data stream having a first unique identifier of an identifier space and having assigned metadata, the metadata comprising meta information and a metadata link, the metadata link comprising the first unique identifier and at least one data packet identifier. When performing an editing operation on the data stream, a second unique identifier of the identifier space is assigned to the data stream and the first unique identifier for a resolver task is stored, using a decision metric for updating the meta link.
Abstract:
A method for automatic detection of data types for data type dependent processing has two orthogonal classification systems defined, and determines for incoming data items a data type according to the first classification system and another data type according to the second classification system. The first classification system comprises the data types Essence, Metadata and Container. The second classification system comprises the data types Physical Data and Abstract Data. A default data type may be defined for data items not being uniquely classifiable. Advantageously, the inventive method can be used when different classes of data items require different methods for processing, e.g. content searching.
Abstract:
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.
Abstract:
A replay appliance for recording media containing information blocks, the appliance comprising means which are independent of the contents directory for access to files and information, and which allows replay even if the contents directory or file system is damaged. The appliance includes search means for searching for a designator of a file which is to be localized in blocks of the recording medium, evaluation means for determining the designator of following bytes which indicate a number of 2048 byte blocks from which the information block is composed, and the information block determined in this way is used for data access. The field of application of the invention extends to replay appliances for recording media containing information blocks, such as a hard disk, a digital versatile disk, which is also referred to as a DVD, a CD-ROM, floppy disk or a data tape, which have a recording format from the so-called Yellow Book.
Abstract:
A method for regenerating the original data of a digitally coded video film is described, in which a specific picture type of a number of picture types (I, B, P) has been allocated to each of the individual pictures during coding and the coding order (DEO) does not correspond, at least in part, to the display order (DIO). This method provides for an independent time base to be used in order to recover the display order, which time base is obtained from internal information items in the decoder, the information items having been stored during the preceding decoding of a number of pictures. This method has the advantage that even with the omission of a header of a Group of Pictures (GOPH), the correct display order can still be achieved, even if the otherwise customary temporal reference codes in the bit stream signal an incorrect display order.

Abstract:
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.
Abstract:
An architecture for a multimedia peer-to-peer home network allows the simple definition of peer groups, or zones, where each peer is capable of automatically identifying whether other peers are members of the same group, or of another group, by using group labels. Each peer may freely cooperate with the other peers of the same group, or with peers of previously specified other groups. e.g. exchange information or share resources. The architecture aims to map an atmosphere of trust existing between users to a technical system. namely their respective home networks. Using this architecture, it is e.g. possible that users who trust each other may give each other access to their own home network, or parts of it.
