Abstract: Exemplary methods for automatically testing closed caption (CC) rendering includes receiving a set of one or more reference audio video (AV) streams from an AV source, and generating reference CC images from the set of one or more reference AV streams starting from a recording start time to a recording stop time. In one embodiment, the method further includes receiving a set of one or more test AV streams from the AV source, and generating test CC images from the set of one or more test AV streams starting from the recording start time to the recording stop time. In one embodiment, the methods further include determining whether the AV source is performing CC rendering properly by automatically comparing the test CC images against the reference CC images.

Abstract: Average picture level (APL) of a display and, in examples, histogram information is used to dynamically adjust the display contrast, or “gamma”, using an exponential function. APL can also be used for DC transmission adjustment and black/white stretch.

Abstract: A method and system for managing performance data of communication lines, such as digital subscriber lines, is disclosed. The method includes receiving from a remote used device an identifier for a particular communications line at a web server; initiating a real-time performance analysis of the line at a network end of the line; receiving real-time performance data and converting the real time performance data to analyzed data; receiving field performance data from the user device; and converting at least one of the field performance data and the real-time performance data from a web-based format to a mainframe format; and sending the converted data to a mainframe for storage corresponding to a file associated with the identifier.

Abstract: The device (V) serves the optical coupling of a light-beam (L) arriving from any optical component with a further-transmitting light-guiding fiber (F). It contains in each case an input-side and output-side coupling body (1,2) with in each case a centric lead-through (13, 22) for leading through the light (L) wherein in the device (V) there is arranged at least one lens (40) or a lens system. Between the input-side (1) and the output-side coupling body (2) there is arranged an intermediate coupling body (3) with a centric lead-Through (34), which in one of the input-side or output-side coupling bodies (1,2) is displaceably and lockably held in a plane, whilst the outer input-side or output-side coupling bodies (1,2) in the intermediate coupling body (3) is counted in an elastically (25) pivotally movable and axially displaceable manner. The device (V) permits a separate angular adjustment or parallel displacement of the input-side and output-side coupling bodies (1, 2) relative to one another.
