Abstract: Content comprising a sequence of original frames at a first frame rate is up-converted to a second, higher, frame rate. Intermediate frames are calculated for temporal positions spaced between temporal positions of the original frames. An output sequence at the second frame rate comprises a repeating pattern of frames and, within each repetition of the pattern, there is: at least one original frame; at least one intermediate frame which is repeated; and at least one frame which is not repeated. The method is suitable for applications where an up-conversion factor is required in the frame rate, such as an up-conversion factor of five to up-convert from the 24 Hz frame rate used for film-based content to the 120 Hz frame rate used by displays. The output sequence can use all of the original frames to reduce detail flicker.

Abstract: This invention relates to a device and a method of generating a first and a second fingerprint (102,104) usable for synchronisation of at least two signals (101,103) and corresponding method and device for synchronising two or more signals. A fingerprint pair is generated on the basis of a segment of a first signal e.g. an audio signal and of a segment of a second signal e.g. a video signal at each synchronisation time point. The generated fingerprint pair(s) are stored in a database (203) and communicated or distributed to a synchronisation device (303). During synchronisation, fingerprint(s) of the audio signal and fingerprint(s) of the video signal to be synchronised are generated and matched against fingerprints in the database. When a match is found, the fingerprints also determine the synchronisation time point, which is used to synchronise the two signals. In this way, a simple, reliable and efficient way of synchronising at least two signals is obtained.

Abstract: A frame-rate conversion system having an interpolation mode and a synchronization mode. The synchronization mode is selected when temporal interpolation confidence is and images can be retimed without dropping or repeating of images. The interpolation mode is selected when the measure of temporal interpolation confidence is high or repeating of images. Images are exchanged between a temporal interpolator and a buffer at an exchange rate which is varied in the interpolation mode to optimise the buffer occupancy for retiming of images without dropping or repeating of images in s subsequent synchronization.

Abstract: A method and apparatus for automatic compensation of insertion loss in signals transmitted over conductors is presented. The present invention is particularly applicable to the transmission of signals over long lengths of CAT-5 or similar twisted-pair cables. A reference signal having a known form and strength (e.g. a pulse signal) is provided to each pair of conductors carrying a component of a signal from a transmitter to a receiver. The receiver includes adjustable gain amplifiers for each conductor pair over which a component of the signal is transmitted. The gains of the amplifiers are initially set at an initial level (e.g., their maximum gain) to allow detection of the reference signal. Once the reference signal is detected in a conductor pair, the amplifier gains are adjusted such that the level of the reference signal is restored approximately to its original form and strength.

Abstract: Systems, methods, and processor readable media are disclosed for encoding and transmitting first media content and second media content using a digital radio broadcast system, such that the second media content can be rendered in synchronization with the first media content by a digital radio broadcast receiver. The disclosed systems, methods, and processor-readable media determine when a receiver will render audio and data content that is transmitted at a given time by the digital radio broadcast transmitter, and adjust the media content accordingly to provide synchronized rendering. In exemplary embodiments, these adjustments can be provided by: 1) inserting timing instructions specifying playback time in the secondary content based on calculated delays; or 2) controlling the timing of sending the primary or secondary content to the transmitter so that it will be rendered in synchronization by the receiver.

The geo-location accuracy of the mode II device affects the TV white space resources which can be allocated to the device.

Abstract: A video terminal and display image forming method are provided that enable power consumption to be reduced while maintaining a moving image display quality level sensed by a user, even if a variety of types of images are displayed superimposed on a moving image, and a method of representing such images is complicated. In a video output apparatus (100), an update rate adjustment section (104) decides a moving image update rate based on a “moving image exposure area.” Specifically, the update rate adjustment section (104) decides an update rate based on an update rate adjustment table in which moving image status pattern candidates are associated with update rate target values, and a moving image status pattern actually used in a display image forming section (103). A moving image status pattern candidate is a combination of “moving image exposure area,” presence or absence of special processing, and type of special processing.
