Description

240526' APPARA'bUS FOR CONTROLLING VIDEO OR AUDIO EQUIPMENT The present

invention relates to apparatus for controlling viddo or audio equipment such as a television (TV), radio, or video cassette recorder (VCR).

Some problems exist with conventional usage of TVs, radios and VCRs. Since the broadcast from only a single channel or station can normally be displayed on a TV set or-heard from a radio, the user may miss a desired programme on another channel or station. In addition, when:ecording a long programme such as a movie on a VCR,Antrusive commercial breaks are captured on the,tape along with the desired programme.

According to the present invention,there is provided apparatus for controlling video or audio equipment, compising:

detect.ing means operable to detect types of TV or radio programmes currently being broadcast on various channels or stations; storage and selecting means operable to store preference information on one or more types of programme prefekred by a user; and operable automatically to select a particular channel or station on the basis of the type of programme being broadcast, taking into account the preference information; and control means operable to cause the video or audio equipment to receive said particular channel or station.

An embodiment of the present invention can find TV/radio broadcasting programmes from stations, indicate the available programmes on a TV screen or on display panel associated with a TV or radio, and automatically tune to the channel that is broadcasting a programme desired by the user.

An embodiment of the present invention can also economically control a VCR tape in a recording operation in such a way as to omit unwanted commercial' broadcasting from the recording. The user's enjoyment of TV and radio broadcasts and of video recordings can therefore be improved.

More specifically. an embodiment of the present invention is operable to find programmes on air by their respective features and to arrange them in the order of user preference. Depending on the programme contents, the desired channel is automatically tuned for receiving or for recording on an audio or video tape. The tape can be controlled so as to omit unwanted signals (e.g commercials) from recording and to resume the recording after the unwanted signals are- it finished.

Preferably, apparatus embodying the present invention includes a display means for displaying information on the types of programmes currently being broadcast. This may comprise a display unit having a two-dimensional array of lights or other display elements, one dimension of the array representing channel number or station frequency, and the other representing programme type.

Reference will now be made by way of example, to the accompanying drawings in which:

Figure 1 is an overall block diagram of apparatus embodying the invention; Figures 2(a) to (d) are descriptive representations of operations of a TV set employing the apparatus; and Figures 3(a) and (b) are flow charts of operations of the apparatus.

Reference signs in the drawings indicate the following features:

1 is a channel signal detector, 2 a memory for program features, 3 a channel display circuit, 4 a display unit, 5 an auto-tunIng circuit, and 6 a VCR recording control.

Figure 1 shows an example of apparatus according to the invention as applied to a TV and VCR.

The apparatus comprises a circuit including a TV/radio broadcasting programme detector 1, an auto-tuner 5 for selection of channels and a tape control 6 for controlling recording operation of the VCR. The channel signal detector 1, which detects all the channel signal (programme) contents from broadcasting stations is connected to a high frequency amplifying circuit of the TV set and also to the memory 2 storing programme features (types) desired or favoured by the user and to a channel display circuit 3 for displaying channels. The circuit 3 further connects to a display unit 4 and to the memory 2,, which further connects to the auto-tuning circuit 5 connecting to a local oscillator in the TV. The memory 2 also connects to the VCR recording control 6 to further connect with the VCR drive motor.

The operation and effect of the invention will now be described in detail An antenna picks up radio waves on air from broadcasting stations, and the channel signal detector 1 finds all the types of programmes in the received waves on the basis of programme features (e.g., movies, drama, shows, commercials,...etc.).

The detection of the type of each programme is effected on the basis of predetermined code signals contained in the broadcast alongside the normal programme. The predetermined code signals are transmitted at least at the start of every programme segment or commercial break, and may be transmitted continuously. The signals sent to the memory 2 from the detector 1 are compared with a list of programme preferences previously stored in the memory by the user to determine the priority order for tuning. The determined channel selection is applied to the auto- tuning circuit 5 as a control signal for the circuit 5, which in turn produces an output signal to drive the TV set's local oscillator, so as to effect auto-tuning to the channel carrying the most preferred programme currently available.

In addition, the output signals from the detector 1 are delivered through the channel display circuit 3 to the display unit 4, to give a visual indication of the selection of programmes currently on is air as shown in Figure 2(d).

The display unit 4 may be provided in the form of a matrix of indicator lights built into the TV set, or in a separate unit; alternatively, a portion of the TV screen itself may be used to provide the display, with the display unit 4 acting to modify the normal driving signal delivered to the electron gun.

The output signals from the detector 1 are compared with the programme types stored as preferences in the memory 2 and a selection is made from the available programmes by supplying an appropriate signal from the auto-tune circuit 5 to the TV set local oscillator. This comparison and selection process is preferably performed whenever the detector 1 detects that the type of programme broadcast on the currently selected channel has changed. on the other hand, it may be preferable not to change channels automatically as soon as a more preferred type of programme becomes available on another channel, before the programme being watched or recorded has finished. This can be left as an optional feature to be chosen or not chosen by the us. er.

in the case of recording a programme using the VCR, the-feature signal applied to the programme feature memory 2 via the line 7 from the detector 1 causes the memory 2 to produce an output control signal to the VCR rgcord control 61so as to drive the VCR drive motor to control the VCR tape. In this way, a programme of-interest to the user can be recorded completely aiitomatically.

An example of operation is as follows.

TABLE I

Channel 2 movie is Channel 3 news Channel 4 show Chanel 5 commercials -Channel 11 news UHF education Suppose that channel stations are broadcasting respective programmes of types as shown in the above Table I, Inclkiding the appropriate identifying code signals as mentioned above, and that the priority order set by the user in the memory 2 is determined as in Table II.

1 TABLE II

Pridrity 1 movie Priority 2 show Priority 3 news Priority 4 drama Priority 5 In this case, when the TV set is switched on, the control apparatus will select channel 2, since this' is currently broadcasting a movie, and tune the TV set accordingly so that the user can watch the movie.

However, if the movie on channel 2 is 3 interrupted by commercials the auto-tuner switches the received channel to Channel 4, so that a show programme.

can be watched by the user in place of the commercials.

Then, if the movie is resumed after the completion of the commercials, the channel signal detector 1 detects this and the selected channel automatically returns-to Channel 2 from Channel 4 to show the next part of the movie. After the movie is completed. the TV set is again automatically tuned to Channel 4 according to the, priority order in the memory 2. so that the user can watch the show being broadcast on that channel.

Meanwhile, if a VCR has been recording the movie, the switching to Channel 4 would interrupt the recording only to resume it on tuning to Channel 2 again. Therefore, no tape is wasted and the movie is recorded without any gaps.

Figure 2 shows descriptive representations for operations of a TV set with the apparatus of the invention. The initial states (preferences) memorized in the memory 2 are shown in Figures 2(a) and (b) with the presently available broadcasts shown in Figure 2(c), the Figure 2(d) showing the outer appearance of the TV with the display unit 4.

Although in the above an example of the present invention has been described in relation to.TVs and VCRs. the invention may also be diversely applied to other audio devices, such as radios and audio recording equipment. Radio broadcasts can be selected, and audio recordings from the radio can be controlled, in the same way as described above.

The present invention thus provides an effective channel control for TVs by automatically tuning the channel to one showing a type of programme of interest to the user, And allows economic use of VCR tapes by preventing unnecessary recording of unwanted programme material such as commercials.
