Abstract

DC60 (14/05/46) Monitoring device (3) which is used to check the image status, TV channel selection of TV set (1) Reference receiver (32), it is free to regenerate or transmit the audio of the TV set. The channel in which the audio signal comparison section (31) is measured. Contract key meter Audio from the TV's speaker-to-speaker (13) and the Important from the reference receiver To check if both audio signals are the same, remote control receiver (34) receives the signal from the remote control (2) to receive information about the channel that I'm going to adjust At the time of office Change the channel of the reference receiver Until the anvil is detected that the equality of the two waves, the control comparison section (37) is shown to the receiver. Based on the first known channel Changing to Which is determined by the signal coming out of the remote control, so it can measure the channel The signal is selected by the TV quickly and accurately. Monitoring device (3) which is used to check the image status, TV channel selection of the TV set (1) reference receiver (32) independently to regenerate or transmit the audio of the measured channel. The audio signal comparison section (31) compares the parameters. Contract key meter The sound of the TV's speaker-to-speaker (13) and the Important from the reference receiver To check if both audio signals are the same, Remote Control Receiver (34) Receives the signal from the remote control (2) to receive information about the channels that I'm going to adjust At the time of office Change the channel of the reference receiver Until the anvil was detected that there is an equalization of the two waves, the control comparison section (37) is shown to the receiver. Based on the first known channel Are changing to Which is determined by the signal coming out of the remote control, so it can measure the channel The signal is selected by the TV quickly and accurately.

Claims (8)

1. The method of displaying the selected TV channel as it is currently receiving the signal from the TV requires that the TV have at least one receiver (11, 12) and a remote control (14) to receive and display the remote control signal from the remote control (2) and to control the receiver's reception status and provide the selected video and audio signals to the screen and speakers, respectively. The method consists of the following steps: (a) receiving and displaying the remote control signal from the remote control and setting the TV channel; and (b) controlling the receiver status of the reference receiver (32) to overlap the audio signals from the reference receiver and the TV speakers, with the reference receiver having the capability to transmit the selected audio channel, respectively. Step (b) consists of the following sub-steps: (b-1) when the audio signal from the reference receiver does not match the audio signal from the TV speakers, the channel assigned in step (a) on the reference receiver is switched to the other channel, in sequence until the selected audio signal is obtained. (b-2) The assignment, for the channel currently selected, is the channel referenced by the receiver at the time when the two audio signals coincide again; and (b-3) Recording to the storage medium (36) The selected channel information contains messages about the channel assigned as the currently selected channel and also messages about the associated times. 2. The method for checking the status of the TV signal selection as described in Claim 1 is defined as follows: The method also includes step (c), which is to check the type of video signal displayed on the TV screen, and the type of video signal from step (c) is recorded in the selected channel information to be recorded on the recording media in step (b-3). 3. The method for checking the status of the TV signal selection as described in Claim 2 is defined as a procedure c, which also consists of the following steps: (c-1) check the transverse timing signal applied to the TV screen; (c-2) count the number of cycles of the transverse timing signal detected in step (c-1); and (c-3) determine the type of video signal displayed on the screen based on the signal received in step (c-2). 4. The method for checking the status of TV channel selection as described in Claim 1 is defined as follows: that procedure (b) includes procedure (b-4) for learning the information about the currently selected channel as defined in procedure (b-2) into the signal log; and procedure (a) includes procedure (a-1) for determining the channel to be switched to based on the result of the signal display received from the remote control and the selected channel being recorded into the channel log; and (a-2) for recording information about the assigned channel into the channel log. 5. The method for checking the status of the TV signal selection as described in Claim 1 is defined as follows (b-1): in step 1, the frequency band of the audio signal from the reference receiver and the frequency band of the audio signal from the TV speaker are calculated; and the frequency bands are compared to determine whether the audio signal from the reference receiver and the audio signal from the TV speaker overlap. 6. TV Channel Selection Status Monitoring Tool (3), which will indicate whether the TV channel (1) is actually being received at that moment, is a TV with at least one built-in receiver (11,12), and a remote control signal receiver (14) to receive and identify the remote control signal from the remote control (2) and control the channel setting status of the built-in receiver, which provides the audio-video and audio signals of the currently received channel for display on the screen and speakers, respectively. The tool consists of: a built-in receiver (32) capable of transmitting the audio signal of the selected channel from all pre-defined channels; an audio signal comparison medium (31) for checking whether the audio signal from the reference receiver and the audio signal from the TV speakers have overlapping bandbands; a remote control signal receiver (34) for receiving and identifying the remote control signal from the remote control to determine the channel currently being received by the TV; a control medium (37) for controlling the channel setting status of the reference receiver so that the output obtained from the comparison remains the same; When such output is converted into a different signal, the channel assigned to the internal receiver's remote control signal is changed to another designated channel in sequence until the desired signal is found by the comparison medium; it is designated as the then-received channel, the channel received by the reference receiver, where the output obtained from the comparison can be perfectly matched; and the selected channel information is recorded as the then-received channel, along with the associated time information; and the recording medium (36) for recording the data is provided by the control unit. 7. The TV signal selection status monitoring instrument, as described in Claim 6, is intended to be such that: the instrument has a medium for monitoring the type of video signal displayed on the TV screen, and the control unit records the type of TV signal onto the video signal data used. 8. The TV signal selection status monitoring instrument, as referred to in claim 6, consists of a video signal monitoring medium comprising (15, 331) for monitoring the transverse rhythmic signal applied to the TV screen, the number of timestamps of the measured transverse rhythmic signal cycles; and a monitoring medium (337) for determining the type of video signal displayed on the screen based on the count of the said counter.
