DESCRIPTION:
BRIEF SUMMARY
With entertainment electronics devices, for example, video recorders, it is known to program transmitters (stations) which can be received at the location of the receiver into a memory facility in the device in order to be able to address these through depressing a key for the purpose of simple operation of the device or by means of a remote control. Thereby, a program location or program number is allocated to a particular station and its channel number which corresponds with a particular frequency. Modern devices exhibit many addressable program locations whereby, the number of the locations can even exceed the number of receivable stations. With such devices it would be possible to allocate all reception channels which can be theoretically received within a large reception area to a program location number each in one programming process. However, only a few of these programmed channels can be received at the reception point. Therefore, for general outline reasons, it is practical to sort the receivable channels, for example, according to the increasing allocation of the program location number. This can happen through individual programming. Also, with a change of reception point the individual programming would have to be carried out again. However, such re-programmings mean a great expenditure of time.
It is the object of the invention to render possible a desired allocation of receivable channels to program location numbers, for example, according to increasing allocation, from the many pre-programmed channels through a simple sorting process.
In principle, always the ratings (channel numbers) stored in two program locations, which are successively called up, are exchanged with each other through internal control within the device.
Thereby, it is possible in a simple way to allow a desired allocation of the receivable channels. In order to make this sorting process as easy as possible for the operator time processes are chosen through which the operator is guided. By depressing a program key intended for the exchange for a longer period of about 1 through 4 seconds, the corresponding program location (program-NR) is marked internally for the exchange with the stored rating (channel-NR). The exchange process is triggered when the data allocated to this program key is read into the auxiliary memory. The memorized data (program-NR and channel-NR) are indicated in devices with a display. Simultaneously, an internal clock starts which, for example, is contained in a microprocessor or is formed from a clock pulse generator and a counter in order to open a time window for about 5 seconds. Likewise, the time window can be indicated, for example, through flashing of the data which has already been displayed for the exchange or by a particular symbol.
Likewise, by depressing a second program location key for a longer period of 1 through 4 seconds within the given time window of 5 seconds, whose rating (channel-NR) is to be exchanged with the first key, this data is also read into an auxiliary memory. Likewise, at the same time an indication for the data (program-NR and channel-NR) allocated to this program location occurs . The desired allocation occurs through an interchange of the ratings (channel-NR) of the two called-up program locations by means of a processor which also controls the displayed indications, this process being known as such from computer technology. Likewise, the resulting interchange can be presented as a confirmation on the display.
Subsequently, the invention shall be better illustrated by means of a FIGURE which shows a block diagram of the circuit arrangement for performing the sorting process according to aspects of the invention.
The FIGURE shows a block circuit diagram for the sorting process. A memory facility 1 has a main memory 8 which can be designed as a dynamic RAM. Let it be assumed that the individual program locations (PR-NR) are already allocated to the ratings (channel-NR) in the main memory 8. A key on the keyboard 7 is allocated to always one program location (PR-NR).
