A graphical on-screen display (OSD) system, includes a decoder for decoding graphical OSD image representative data from an auxiliary information component of a video signal. An edge detector is coupled to the decoder and processes the OSD image representative data to detect an edge in the graphical OSD image. An edge smoother is coupled to both the decoder and the edge detector and generates signals representing a reproduced OSD image having a smoothed edge when an edge is detected.

Information is coupled to a data bus such as an I C 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.

An auxiliary digital data extractor in a television receiver includes a source of a composite video signal. The composite video signal includes an auxiliary digital data component which is either a first frame code having a predetermined number of bits and auxiliary data in a first format, or a second frame code having the same number of bits and auxiliary data in a second format. A frame code detector is coupled to the composite video signal source. The frame code detector is responsive to one subset of the frame code bits to detect the first frame code and to a different subset of frame code bits to detect the second frame code. An auxiliary data utilization circuit is coupled to the composite video signal source and the frame code detector. The auxiliary data utilization circuit receives auxiliary data in the either first format when the first frame code is detected or the second format when the second frame code is detected.

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.

A tuning system for tuning non-standard frequency RF television signals provided by cable distribution networks and television accessories conducts first and second consecutive searches by changing the local oscillator frequency. The first search is limited to search frequencies corresponding to predictable non-standard frequencies associated with the major cable distribution networks. The second search includes more search frequencies and extends over a wider frequency range than the first. During an auto-programming mode, in which active channels are identified, for memorization in a channel list portion of a memory, only the first search is conducted to minimize the required time.

A character generator in a receiver provides a character signal in raster scan form for display with a received video signal. An oscillator, not synchronized with the horizontal synchronizing component of the video signal, supplies a clock signal to the generator for controlling timing of character elements. A control unit provides a control signal representative of a time difference between the clock signal and the horizontal synchronizing component. A delay unit, interposed in the clock signal path, selectively imparts delay to the clock signal in response to the control signal for reducing line-to-line variations in the timing of displayed character elements.

A system for processing auxiliary video information, such as closed caption information, includes capability for detecting invalid parity errors that may be created by video signal distortion effects caused by sync suppression video signal scrambling. The sync suppression distortion does not affect the video display but may modify the parity bit of the second of two closed caption characters in each occurrence of line 21 of field 1 causing invalid parity errors. Parity errors in the first character, which is unaffected by the sync suppression distortion, indicate whether valid parity errors exist in the second character. If no parity errors occur in the first character, parity errors that occur in the second character are considered to be invalid.

A digital fine tuning system for a television receiver includes a counter arrangement for measuring the frequency of the IF picture carrier by counting cycles of the IF picture carrier during a measurement interval and comparing the count at the end of the measurement interval to a predetermined count related to the nominal frequency of the IF picture carrier. To prevent counting, and thereby frequency measurement errors, due to the overmodulation of the picture carrier during image intervals, the frequency measurement operation is enabled during a predetermined portion of the vertical retrace interval when the picture carrier is not overmodulated.
