摘要： A non-invasive or minimally invasive intermediate frequency (I.F.) probe is disclosed for use as part of a broadcast audience measurement system. The probe can be used both to acquire a representation of a tuned signal and to inject a recognition signal into a tuned signal. The probe is configurable for use with both analog (e.g., NTSC, PAL or SECAM) and digital (e.g., ATSC) television broadcasts. Optionally, when in the injection mode, the I.F. probe can be used with another sensor;to determine which of several inputs to a monitored receiver is providing the audio and/or video output(s) selected by an audience member.

摘要： An apparatus for acquiring a modified baseband video signal from a CRT of a receiver includes a capacitive pick-up disposed on an external surface of a housing of the receiver and adjacent to a socket of the CRT, and two inductive pick ups having substantially mutually perpendicular axes disposed on the external surface of the housing and spaced apart from the capacitive pickup. The capacitive pick up senses a video signal of the receiver, and the inductive pick ups sense horizontal and vertical sync signals of the receiver. A horizontal sync component of the video signal is replaced in response to the horizontal sync signal sensed by the inductive pick ups. A filter is arranged to filter out a band of frequencies centered about an integral multiple of a power line frequency. The capacitive pick up has a capacitive pick up plate and a capacitive shield plate which is located farther from the socket than the capacitive pick-up plate. An axis of one of the two inductive pick ups is parallel to an axis of the CRT.
