Abstract

Abstract Television receiver including a search tuning circuit for automatically searching tuning data of TV programs in an RF TV reception frequency band after a search activation signal, a tuning device for tuning the TV receiver to a TV program found by the search tuning circuit, and a preset programming device for manually storing said tuning data in a tuning memory at a location from which the tuning data is addressable by operating a program preset key. For simple programming of the preset keys a tuning data found by the search tuning circuit is automatically stored in a buffer memory, which buffer memory, after initiation of the preset programming device, supplies the tuning data to the tuning device for tuning the TV receiver to and identifying the TV program corresponding to the tuning data, followed by said manual storage.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 133 words
A television receiver including a search tuning circuit for automatically searching tuning data of television programs in a television frequency band after a search activation signal, a tuning device for tuning the television receiver to a television program found by the search tuning circuit, and a preset programming device for manually storing said tuning data in a tuning memory at a location from which the tuning data is readable by operating a program preset key, characterized by an automatic storage of a tuning data found by the search tuning circuit in a buffer memory, which buffer memory, after initiation of the preset programming device, supplies the tuning data to the tuning device for tuning the television receiver to and identifying the television program corresponding to the tuning data, followed by said manual storage.
Claim 2
Dependent Claim 71 words
A television receiver as claimed in Claim 1, characterized in that the tuning device comprises first and second tuning stages via which first tuning stage the receiver is tuned for displaying a television program signal and the second tuning stage is controlled by the search tuning circuit for searching the tuning data of at least one television program in a television frequency band and for storing it in the buffer memory.
Claim 3
Dependent Claim 47 words
A television receiver as claimed in Claim 1 or 2, characterized in that tuning data of various television programs in a television frequency band are automatically stored successively in the buffer memory, followed by a program-sequential identification and storage of said tuning data in the tuning memory.
Claim 4
Dependent Claim 57 words
A television receiver as claimed in Claim 2, characterized in that after initiating the preset programming device the buffer memory alternately supplies the tuning data to the first and the second tuning stage, said two tuning stages being alternately controlled in a mutually opposite alternation from the search tuning circuit or being set from the buffer memory.
