An extreme ultraviolet radiation generator is disclosed in which Xenon gas is continuously ejected from a high pressure nozzle into a low pressure chamber to generate Xenon atom clusters which are irradiated with a high repetition rate pulsed laser to form a plasma and yield quasi-continuous EUV generation. The nozzle has a beveled outer rim to enable the focus point of the laser light to be brought close to the nozzle. The nozzle is cooled to a temperature at which background Xenon gas condenses onto the nozzle forming a protective layer. A gas compressor serves to recirculate the Xenon gas and batch purification triggered by a mass spectrometer monitoring gas purity may be periodically applied.

A laser is disclosed which includes a gain medium, a switch element, and a pulse controller. In one embodiment laser light of differing polarizations pass along respective paths and a pulsed laser output is generated via an electro-optical element. In another embodiment light of differing polarizations passes in differing directions through a cyclical path. The invention can make use of a prism-shaped polarizer having a polarization selection face and two further faces. Yet further initial pulses can be controlled to reduce energy, for example by progressively increasing the period or amplitude of successive pulses. As a result an efficient and high power laser apparatus is realized.

Enabling the automatic identification of participants to a common event to enable data sharing between the participants. An event identifier embedded in the content data associates the content data with an event. A content data service maintains a list of event identifiers and a list of participants associated with each event. Each of the participants communicates with the content data service to identify the other participants. The participants communicate with each other to share content data from the common event.

Enabling efficient navigation of a playlist of media files stored on a computer-readable medium. Aspects of the invention define a playlist structure to have one or more playlist units. Each playlist unit identifies one or more media files in the playlist and includes metadata for the media files. A consumer electronic device retrieves the playlist units and displays the metadata contained therein to a user to enable navigation of the playlist. Aspects of the invention reduce the memory requirements of the consumer electronic devices and reduce the quantity of disk seek operations needed for playlist navigation.

[Problem] There has been a problem that, in the case where a plurality of play list files are recorded in a record medium such as a CD-R, it is difficult to manage the play list files. [Means for Solution] A recording and reproducing system has a CD-RW medium 15 for holding a plurality of play list files for storing a play list describing reproduction order of a plurality of data files, a file recording means 14 of storing in a play list file menu file a play list file menu which is information for selecting a predetermined play list file, a menu definition file creating means 33, a controlling means 21 of displaying play list file menu information on all or a part of the stored play list file menus and selecting the predetermined play list file according to an instruction, a reproduction instructing means 22, a file reproducing means 23, and a data file output means 24.
摘要:
A software program for creating features for use with a plurality of media objects in a sequence. The program comprises a feature component specifying a feature having parameters affecting at least one variable aspect of the feature. An indicator component identifies a position of the specified feature relative to the media objects in the sequence. The program comprises a sequence generator for modifying the specified feature by varying its parameters of the specified feature as a function of the position of the specified feature relative to the media objects and/or relative to other features in the sequence. The sequence generator also modifies the specified feature by varying its parameters of the feature as a function of the content of the media objects around it or to which it has been applied. A rendering component renders the specified feature according to the varied parameters at the identified position.
摘要:
A recording and reproducing system includes a DVD-RAM medium having a plurality of data files of storing predetermined data, file recording means of recording, in a play list file held by the DVD-RAM medium, a play list of describing reproduction order of reproducing the predetermined data stored in each of all or a part of the data files out of the plurality of data files by using a file name of the data file and a unique directory ID provided to a directory to which the data file belongs, and file reproducing means of reproducing the predetermined data stored by each of all or a part of the data files out of the plurality of data files based on the recorded play list.
摘要:
A method and system for segmenting video into an optimal set of video clusters that correspond loosely to one or more events, date ranges, time ranges, chapters or other logical segmentations of the digital video that is meaningful to the user. Video shots are selected from one or more video files on a computer-readable medium. The video shots are arranged in chronological order and a distance (e.g., time gap) between each successive pair of the arranged video shots is determined. Video clustering are generated as function of the determined ‘distances’ and/or user input, and an optimal video clustering is identified. After the optimal video clustering is identified, a time span for each of the video clusters is determined and a label is generated for each cluster. The clusters are then displayed for the user to browse using the generated labels and thumbnails derived from the video clips, transferred to a separate medium for display on another computer or other electronic device (e.g. DVD-video player) or made available for the user or other software to manipulate further.
