摘要： Improved systems and methods for timing athletic events. A radio-based starter unit and a radio based timer unit communicate wirelessly via radio. Push buttons/switches and lights and a speaker in the units provide an intuitive, easy to use interface. Handshaking occurs between the starter unit and the timer unit, and lights indicate that the event is ready to start. Real time clocks in the units are synchronized. Upon detection of race or other event start, such as from a starter's pistol, information indicative of the race start time is transmitted from the start unit to the timer unit. A camera in communication with the timer unit provides video frames, and the timer unit encodes and inserts elapsed time information in the video frames, which are then output from the timer unit for review and analysis on a computer.

摘要： A switcher using shared processors has an input matrix with a plurality of inputs to which a corresponding plurality of sources may be coupled. One or more of the sources may provide compressed data. The input matrix routes selected ones of the sources to a plurality of outputs which is less in number than the number of inputs, the routing being determined by a tally output. A pool of processors, such as compression decoders, color correctors or the like, are coupled to the outputs of the input matrix as needed for processing those sources that require such processing to provide processed data. The outputs of the processors provide processed data to a conventional switcher that combines the selected processed data to provide a program output. The conventional switcher also provides the tally output. For sources that provide inter-frame compressed data, the conventional switcher provides a preview output and a preview tally output so that the necessary time delay for decompressing such data is anticipated to minimize delay in switching the preview output to the program output. A resource management module keeps track of which processors are committed to which sources.

摘要： An apparatus for counting the number of times that each of a large number of digital data patterns are present on a set of signal lines comprises a plurality of random access memories (RAMs) and a feedback means, arranged to form an array of linear feedback shift registers. The data to be analyzed is applied to the address inputs of the RAMs where it selects one of the linear feedback shift registers in the array. A data-valid signal associated with this data causes the selected linear feedback shift register to increment (or decrement) in its pseudo-random count. After the analysis period is over, the value at each address is read out and translated using a lookup table or other translating means from the pseudo-random code of the linear feedback shift register into a meaningful number. This result may then be displayed; for example, in a histogram. An improved feedback path for the linear feedback shift register avoids hang-up states and the need for initialization. A mux can be used to switch between two alternative feedback paths, allowing the apparatus to operate in a count-up mode or a count-down mode.

摘要： A signal generator for producing a triggered output signal of digitally controlled phase and frequency includes a skewing circuit for producing an output clock signal of the same period, T, as an input, triggered reference clock signal but which is phase skewed from the reference clock signal by a phase angle, P, of 0 to 360 degrees as determined by input digital data. The skewed clock signal is frequency divided by an integer factor N, and a timing circuit counts reference clock periods to initiate frequency division a programmable delay time (J.times.T seconds) following triggering of the reference clock signal, where J and N are integers also determined by input digital data. An AND gate qualifies the frequency divided skewed clock signal with the skewed clock signal itself to produce a periodic output signal of digitally controlled frequency N/T, the first pulse of which is delayed following triggering of the reference signal by a digitally controlled interval of (T.times.J)+(P.times.T/360) seconds.

摘要： An enhanced video data compressor has a composite video signal decoder that changes the state of a field identification signal in response to a vertical interval indicator in composite video data which is in a digital video format. Thereafter a vertical timing pulse is generated to prepare a compression encoder to acquire data. By counting lines from the vertical timing pulse the decoder sets a horizontal timing signal at a one macroblock line interval prior to active video data so that the compression encoder acquires video data from the vertical interval as well as active video data. At the end of each field the acquired data is processed by the compression encoder to produce compressed video data.

摘要： An analog-to-digital converter latching circuit functions alternatively in a degenerative mode and a regenerative mode. During degeneration, circuit stray capacitances are substantially discharged for resulting in fast operation. When the circuit switches from degeneration to regeneration, a small signal current is able to start the latch in the proper direction without first having to overcome charge stored in the stray capacitances.
