摘要： An auxiliary video information decoder for decoding information such as closed caption data in a video signal identifies a desired horizontal line of video in a video signal. A reference pulse in a synchronizing signal is detected followed by the generation of first and second window pulse signals occurring at predetermined delays after detection of the reference pulse. A pulse occurring in the synchronizing signal during the window pulses indicates the start of the desired horizontal line interval. A field identification signal may also be generated. Features for improving noise and phase error immunity when identifying a video line are provided.

摘要： A data slicer for extracting auxiliary video data from a video signal adapts a data slicing level to the amplitude of the data signal as indicated by the average value of a run-in clock (RIC) signal that is included in the video signal. Control of the slicing level occurs during a window interval that spans a portion of the RIC signal. A comparator compares the video signal to a slicing level established at the output of a digital to analog converter. A digital system monitors the output of the comparator during the RIC window to determine both the existence of auxiliary video data and the accuracy of the slicing level. The slicing level is adjusted in response to the comparator output to establish a slicing level related to the RIC signal amplitude.

摘要： A double conversion tuner stabilized against drift includes a first local oscillator included in a phase locked loop (PLL) and a second local oscillator included in an automatic fine tuning (AFT) loop. A switching arrangement selectively allows the AFT signal to control the second local oscillator only when the operation of the PLL has been completed and if the picture carrier of the IF signal produced at the output of the tuner is within the AFT control range to prevent the second local oscillator from being tuned incorrectly.

摘要： In a tuning system of a television receiver, the local oscillator (LO) signal and IF picture carrier are selectively coupled to the clock input of the same down counter. The down counter is selectively enabled to count cycles of the LO signal on IF picture carrier during respective LO and IF measurement intervals. A predetermined initial count related to a desired frequency of the LO signal or a predetermined initial count related to a desired frequency of the IF picture carrier are loaded into the down counter during LO and IF presetting intervals which occur just prior to corresponding LO and IF measurement intervals. The counts of the counter at the ends of each of the LO and IF measurement intervals are compared to zero to generate LO and IF error signals representing the frequency deviations, if any, of the LO signal and the IF picture carrier from the respective desired frequencies. The LO and If error signals are utilized to control a tuning voltage for the receiver's tuner.

摘要： Information is coupled to a data bus such as an I2C data bus using a push-pull circuit. The push-pull circuit provides for communicating on the data bus at two different data rates. The push-pull circuit includes an active pull-up device that is enabled during a first push-pull mode of operation for providing a high data rate. During a second normal mode of operation, the active pull-up device is disabled providing a low data rate. When the active pull-up device is deactivated, the clock and data buses are driven by the external resistors connected thereto at a data rate lower than the data rate during the first mode.

摘要： An auxiliary video information decoder for extracting an auxiliary video information signal from a video signal includes a data slicer and apparatus for adjusting the slicing level of the data slicer. The slicing level is adjusted rapidly until a reference component of the auxiliary information signal is detected during a display interval of the video signal in which auxiliary video information is expected to occur. A count is incremented after display intervals in which the reference component is detected and is decremented after display intervals in which the reference component is not detected. Slicing level adjustment ceases while the count is at least a predetermined number. The apparatus rapidly adapts the slicing level to long-term video signal amplitude changes of significant magnitude (e.g. following a channel change) and maintains a constant slicing level when transient variations occur in the video signal amplitude.

摘要： In a television receiver, a keyboard encoding arrangement which makes use of an existing register for storing binary signals representing control information and existing connections coupled to respective stages of the register includes transmission gates for selectively coupling the connections to respective switches of a keyboard. The switches of the keyboard are also coupled to sense circuits for detecting the presence or absence of binary signals. A counter selectively counts in response to sense signals generated by the sense circuits and generates count-representative signals which control the selective coupling and decoupling of binary signals stored in the register to the sense circuits through operated switches of the keyboard. A decoder is responsive to the count signals to generate control signals related to operated switches.
