摘要:
Embodiments of the invention include a subtitling format encompassing elements of enhanced syntax and semantic to provide improved animation capabilities. The disclosed elements improve subtitle performance without stressing the available subtitle bitrate. This will become essential for authoring content of high-end HDTV subtitles in pre-recorded format, which can be broadcast or stored on high capacity optical media, e.g. the Blue-ray Disc. Embodiments of the invention include abilities for improved authoring possibilities for the content production to animate subtitles. For subtitles that are separate from AV material, a method includes using one or more superimposed subtitle layers, and displaying only a selected part of the transferred subtitles at a time. Further, colors of a selected part of the displayed subtitles may be modified, e.g. highlighted.

Subtitling aims at the presentation of text information and graphical data, encoded as pixel bitmaps. The size of subtitle bitmaps may exceed video frame dimensions, so that only portions are displayed at a time. The bitmaps are a separate layer lying above the video, e.g. for synchronized video subtitles, animations and navigation menus, and therefore contain many transparent pixels. An advanced adaptation for bitmap encoding for HDTV, e.g. 1920.times.1280 pixels per frame as defined for the Blu-ray Disc Prerecorded format, providing optimized compression results for such subtitling bitmaps, is achieved by a four-stage run length encoding. Shorter or longer sequences of pixels of a preferred color, e.g. transparent, are encoded using the second or third shortest code words, while single pixels of different color are encoded using the shortest code words, and sequences of pixels of equal color use the third or fourth shortest code words.

A comfortable method and device for searching databases are required. Thus, a database access concept including an interface descriptor is proposed. The interface descriptor may be a XML-file which describes interface categories and database access strategies. The database interface machine may comprise a standard category display method and a standard database access method. The database interface machine can use the definitions contained in the interface descriptor to set up a categorized interface to the database and to perform complete database searches.

Available storage media capacity for personal video recording increases continuously. metadata can be used to organize the recordings, search for content and access specific recordings. If metadata are embedded within the multimedia content itself, like DVB specific Service Information, which are multiplexed with the audio and video streams to form a MPEG-2 transport stream, a search based on this metadata would require an inefficient and time consuming search through all multimedia content stored. According to the invention metadata information is gathered, analyzed and processed to form metadata entities, which are amended by a reference to the content itself. A descriptor stream is formed from the resulting pairs of metadata entities and references to the content and is stored separately from the files comprising multimedia content. In this way, for data of an MPEG-2 transport stream the metadata can be accessed without a need to reparse the entire stream.

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.

Available storage media capacity will be doubling every 2 years. In 2005 it will likely be possible to store about 80 movies on a single 400 GByte hard disk. Because it is no longer possible to access specific recordings stored in a book shelf by just looking at the video cassettes or discs and some annotations on their cover, personal video or audio recording will require new ways to organise and electronically search for content, including automatic content referencing and automatic content location. According to the invention the URI string is extended by additional information that allows to locate specific information within a file that is referenced by such URI. Similar types of URI extensions are used for describing trick mode information. Such extensions take into account specific requirements of the storage format involved.
