摘要： A method for optimizing a scheduler for an optical pick-up reduces switch times required for seamless video angle switching. The pick-up reads data streams from different files on an optical storage medium, e.g. Blu-Ray disc. Seamless video angle switching requires reading and buffering a new video data stream from another file, delaying the switch to be visible. Labels that mark entry points for seamless angle switching are attached to the video stream, and are stored together with the video data in a buffer. When an angle switch is requested, and thus a switch to a new video data stream, the scheduler determines the time before data from the new data stream can be buffered, detects the next label, and stores the new data beyond the label, thus flushing non-relevant parts of the previous buffer contents.

摘要： Optical discs may support “Out Of Multiplex” formats, meaning that different presentation components, like video, audio and subtitles, are stored on different files on the disc, e.g. Blu-ray discs. The different data streams are read by a single pick-up, requiring frequent pick-up jumps and extensive data buffering. The method for operating a scheduler for an optical pick-up reduces the number of pick-up jumps while optimizing the required buffer space. The scheduler is based on a static schema, meaning that the buffer for the data stream with the highest data rate is of minimal size, and therefore refilled in short periods while the buffers for the lower rated streams are dimensioned such that they can be refilled in multiples of the short period. Deviations from the static schema may be allowed, e.g. due to multi-angle video technique. Afterwards the scheduler returns to the original schedule.

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 e.g. “unselected”, “selected” or “activated”. According to the invention, the menu may contain buttons that can be selected through the keys on the remote control, but that don't have any images or text associated. This allows creating “invisible buttons” that automatically execute commands upon selection. 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. Such menu data may be stored e.g. on a Blu-ray disc.

摘要： 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, which comprises descriptors 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.

摘要： A method for optimizing a scheduler for an optical pick-up reduces the pick-up jump frequency and the initial start-up time for reproduction. The pick-up reads data streams from different files on an optical storage medium, e.g. Blu-Ray disc, and buffers the data streams in separate buffers, e.g. for video, audio and subtitles. Buffer sizes are optimized when the video buffer is as small as possible, i.e. large enough to bridge the pick-up access and read times for the other streams, and the buffers for the lower rated streams are extended such that the pick-up access frequency for lower rated streams is an integer multiple of the pick-up access frequency for the highest rated stream, usually the video stream. Initial start-up time is minimized by filling the buffers initially only to a minimum required level.

摘要： The gist of the invention is 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. The invention includes abilities for improved authoring possibilities for the content production to animate subtitles. For subtitles that are separate from AV material, the 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.
