DE4303942C2 - Additional device for the suppression of advertising spots on TVs and video recordings - Google Patents

Description

The invention relates to a device which is independent of television stations control a television and / or a video recorder can. Such a device is from US Pat. No. 4,888,796 known. There a receiver is switched off as long as that Playback material contains a signal for unwanted scenes the control signal being transmitted on a secondary channel can.

The object of the invention is a device of the beginning described type to improve that a multi-channel Receiver can be controlled more differently, e.g. B. to change the channel for the duration of the advertising break and switch back yourself at the end of the advertising break.

This object is achieved by a device with the features of the patent claim 1 solved.

To control all TVs and VCRs on the market To be able to, the device uses its own infrared transmitter. Of the The user must first assign the assignment of his Store channels. The device has infrared Receiver and a memory that keeps track of which transmitter through which IR signal can be selected.

Transmitter and receiver are between the sender and receiver of the Remote control brought (glued or with suction cup). To this This way the television can be operated as usual and the device is constantly informed about the current channel.

Advantages achieved: simple assembly, cheap manufacture, universally suitable for all televisions and video recorders, independent of TV stations, fully automatic operation, Additional benefit.

The user guidance depends on the components used: Display, switches or buttons allow selection, storage and changes to user-related settings. Adjustable would be z. B. the reaction to commercials, feature films or news.

Examples of adjustable device functions:

• - For commercials, switch to the next ad-free channel and back immediately after the end of the spot.
• - Interrupt the video recording for the duration of spots.
• - Automatic switch to programs that make the user special interested (news, sports), so the beginning of this Shipments are not missed.
• - Record all movies without time programming.
• - Blocking sex movies for children from television.
• - Quiet spots during spots for music programs.

The user guidance is interchangeable in the EPROM. The Categorization of the programs in z. B. Advertising, sports, news make employees of a central office, all of them constantly Watch the station and make the setting almost simultaneously can. The categorization will be along with the station name encoded as a signal and broadcast over the entire area suitable frequency (e.g. shortwave) from the central office to everyone Devices broadcast. These have the right recipient and decoder. To the frequency band and the receiver signal Processors have little requirements because of the Language range of the signals to be transmitted can be kept small can. Depending on the width of the frequency band that can be used in the respective country can also transmit, store or store more information are displayed (news, advertising). The Users are informed about events in channels that he would otherwise miss, e.g. B. "Feature film beginning on ZDF". Of course with acoustic warning and even if the television is switched off.

An embodiment of the invention is shown in the drawing and will be described in more detail below. In the drawings Fig. 1 and 2 the auxiliary device.

Fig. 1 shows the typical device constellation in the household a television and nearby (below) a video recorder. The invention can be installed in a device which is the size of a CD player. So you could put it on the TV and connect it to the 220 volt network. The device has a receiving antenna 1 which receives the control signals 2 emitted by the employees 3 .

The infrared transmitters and receivers are simply attached to the television and video recorder, precisely above the infrared receiver of the devices to be controlled 4 .

Fig. 2: The attachment of the two infrared transmitters and receivers is unmistakable, with the adhesive side (transmitter) facing the receiver and the receiver side facing outwards (towards the remote control). Both the television 13 and the video recorder 17 can be controlled as usual via the remote control 5 .

The central unit 6 (chip) can detect and send 11 IR signals by means of a decoder 12 . It is stored in the permanent memory 13 and the software is interchangeably stored in an EPROM 14 . Display 9 , display controller 10 , control panel 16 and controller 15 belong to the prior art. The receiving unit 7 and the signal decoder 8 have the task of representing the necessary information about the events in the transmitters again in binary form.

Claims (3)
