Abstract

A programmable recorder that records video signals provided by a settop box includes monitoring circuitry which monitors a signal indicative of the operational state of the settop box and generates a state signal, logic circuitry which determines whether the settop box is operational based on the state signal and generates a determination signal, and control circuitry which effects a programmed response in response to the determination signal. If desired, the programmed response is cancellation of a schedule recording event. In an exemplary case, the programmable recorder includes an alarm circuit; thus, the programmed response is providing an alarm indicating that the settop box is not operational. In another exemplary case, the programmable recorder includes a communications circuit permitting communication between the programmable recorder and a settop box control facility, and the programmed response consists of transmitting an electronic message to settop box control facility indicating that the settop box is not operational. A memory storing computer readable instructions for permitting the programmable recorded to effect the monitoring and programmed responses and a corresponding signal are also described.

3. The memory as recited in claim 1, wherein:

the video source comprises an antenna; and

the output comprises an alarm signal indicating that the programmable TV recorder is not receiving the video signal at the input port.

4. The memory as recited in claim 1, wherein the output is a signal which cancels a scheduled recording event.

5. A memory associated with a programmable TV recorder storing computer readable instructions for programming a processor to monitor a video signal from a video signal source for changes, to determine, based on said changes, whether the video signal is recordable and to generate an output signal when the processor determines that the video signal is not recordable.

6. The memory as recited in claim 5, wherein:

the processor is programmed to determine that the video signal is recordable when the video signal analyzed by the processor is changing.

7. The memory as recited in claim 5, wherein:

the processor is programmed to determine that the video signal is recordable when a portion of the video signal in a video frame monitored by the processor changes with respect to the corresponding portion of the signal in another frame.

8. The memory as recited in claim 5, wherein:

the processor is programmed to send at least one command signal to the video source and to determine that the video signal is recordable when the video signal monitored by the processor varies dynamically in response to the command signal.
