Methods and systems for defining a compression and reconstruction scheme of a media stream, for generating and transmitting a base media layer and enhancement data layers and for reconstructing compressed representations of the media stream from the base media layer and the enhancement data layers.

A method and system generates and compares fingerprints for videos in a video library. The video fingerprints provide a compact representation of the temporal locations of discontinuities in the video that can be used to quickly and efficiently identify video content. Discontinuities can be, for example, shot boundaries in the video frame sequence or silent points in the audio stream. Because the fingerprints are based on structural discontinuity characteristics rather than exact bit sequences, visual content of videos can be effectively compared even when there are small differences between the videos in compression factors, source resolutions, start and stop times, frame rates, and so on. Comparison of video fingerprints can be used, for example, to search for and remove copyright protected videos from a video library. Furthermore, duplicate videos can be detected and discarded in order to preserve storage space.

A method and a device for maintenance of an elevator or escalator installation includes an interface for connection of a controller of the installation with a display and control unit for display of operating parameters or for input of control commands and data, and connection equipment for creating a data connection with a maintenance center. Data and parameters stored in the maintenance center can be transferred to the display and control unit by the data connection after an identification check. A fault log with a specification of operating faults and / or a specification of the replacement parts coming into question for rectification of the operating faults can be produced, which is transferred by the data connection from the display and control unit to the maintenance center, can be produced for example to cause ordering of missing replacement parts.

A method for automatically generating test programs includes receiving a description of a system under test, expressed in terms of variables associated with the system and conditional constraints including semantics applied to the variables, and receiving a definition of an event to be tested in the system. The method generates an ECondCSP over the variables responsively to the definition of the event and to the conditional constraints, such that at least some of the semantics of the conditional constraints are preserved in the ECondCSP when one or more of the variables to which the semantics are applied are inactive. The ECondCSP is solved to generate a test case for the system.

The present invention comprises a system and method for speech recognition utilizing a multi-language dictionary, and may include a recognizer that is configured to compare input speech data to a series of dictionary entries from the multi-language dictionary to detect a recognized phrase or command. The multi-language dictionary may be implemented with a mixed-language technique that utilizes dictionary entries which incorporate multiple different languages such as Cantonese and English. The speech recognizer may thus advantageously achieve more accurate speech recognition accuracy in an efficient and compact manner.

A memory is encoded with a data structure that represents a pattern having a range for one or more dimensions and / or positions of line segments therein. The data structure identifies two or more line segments that are located at a boundary of the pattern. The data structure also includes at least one set of values that identify a maximum limit and a minimum limit (i.e. the range) between which relative location and / or dimension of an additional line segment of the pattern in a portion of a layout of an integrated circuit (IC) chip, represents a defect in the IC chip when fabricated. In most embodiments, multiple ranges are specified in such a range defining pattern for example a width range is specified for the width of a trace of material in the layout and a spacing range is specified for the separation distance between two adjacent traces in the layout.
