DE2356969C2 - Arrangement for the wireless or cable transmission of pre-produced television recordings - Google Patents

Description

an image and sound reproduction device (6) for playing back pre-produced television recordings, 15 B a receiving stage (3) for remote control pulses sent out by the central broadcasting station (A),

III) a control unit (5), which the function of the image and sound reproduction device (6) in dependent 20 control of the remote control pulses, and

IV) a switching device (4) which is connected to the output of the receiving stage (3) and, depending on the remote control pulses, transmits either the television program coming from the central broadcasting company (A) or one of the video and C sound -Player (6) causes coming television program.

The invention relates to an arrangement according to the preamble of the patent claim.

It is known that today's television converters receive, convert and image and sound signals broadcast more intensely in a reception area in which the central transmitting devices, for technical reasons, can not radiate. The television converters are only used on one side at great expense today.

The invention is based on the object, apart from the / to enable national television programs also a local television program and thus z. B. important communications about healthcare, church, and culture, such as emergency medical services, vaccination, and To enable blood donation appointments or consumer information in the local area.

The object is achieved according to the invention by the features specified in the patent claim.

The pre-produced image and sound material is produced according to its current state and is done manually from time to time exchanged.

The advantages achieved with this invention are in particular that instead of a program of the Broadcasting corporations, an additional, prefabricated, Informative, local regional-local program broadcast on demand via remote control will.

For wanderlust converter or cable TV central network is according to the invention a Umschaltcinrich-UiMg required, click the HiId and Sound signal, consisting of national information, can be transmitted and at the request of a Scndeansliill a picture and sound signal reproduction, consisting of air. local information, from the Fcrnsch-Umsctzcr or cable television Zcntralverlcilcr, allows. The switching device detects all signals, including those that are suitable by means of decoder or decoding to generate a television picture.

Cable television central distributors are available to a small extent, but not for the purpose of the invention Disposal. With the planned regional, local cabling, the facilities can be configured according to the Invention to be incorporated into the cable television central distributors.

An embodiment of the invention is shown in 2 drawings and will be described in more detail below described.

It is shown in sketch 1:

Regional-local television reception and transmission system as well as television converters or cable television central distributors;

Receiving stage for the picture and sound signal from the central transmitter system A;

Amplifier stage and transmission to the transmitting antenna of B;

Receiving stage for control pulses from A;
Switching device for the program from A or from the image and sound reproduction device 6;
Control unit depending on the remote control of A;

Image and sound reproducer;
Subscribers, namely television picture and sound receivers.

It is shown in sketch 2:

a control center for programming;
b Studio:
j5 c remote control pulses;

d directional radio or cable to large transmitter A;

A major broadcaster or cable television main distributor;

B ' plant like B (sketch I), in the immediate vicinity of a plant A;
B ² system like B (sketch 1), for additional reception

for participant C of Appendix A; B ³ system as in B (sketch I) Reception for participant O:

C subscriber without reception from a system B;
O participant like C (sketch 1), reception from plant

Mouth B; C participants like C (sketch 1). Receipt of attachment Mouth B ² ;

O participants ^w:, e C (Diagram 1), reception only from plant &.

Communication flow of the state-of-the-art systems:

The picture-sound signals come from system A and are recorded by # 'and converted and amplified and transmitted to subscriber C, and the transmitted signals from A reach subscribers C to C' directly.

Communication process according to the design of the systems according to the invention, ie Λ (sketch 2) is supplemented by c, B (sketch I) is supplemented by 3—6:

Both systems will be used in the transition phase, that is. Transmission by means of a television converter or cable television central distributor from the reference point Λ in the direction Ii ¹ 'to O '.

Basic example

In studio b a program is kept wide for system A , and in B ^l ~ ³ another program is stored in 6 upstream and ready for retrieval.

The participants labeled O ~ ^s await this program on their television screens.

Technically, the process proceeds such that the plants are put in readiness for operation and tone image signals are applied to the transmitter A in the direction the central unit a. By controlling by means of c via B, switching device 4, the control center a is able to call up the program from the systems B> - ^} for the participants O -!.

A second example allows subscribers O ⁺³ to connect to the switchable systems ß ¹ or S- 'during wireless transmission. When wiring, only follow the basic example because of the greater effect.

Subscriber C is exclusively dependent on national ίο wireless broadcasts.
