Abstract: Transmitter station for transmitting, and receiver for receiving a plurality of television programs via respective transmission channels. A teletext page with tuning data, which are representative of the transmission channels used by the transmitter station is transmitted by one of the programs, for example, a local television program. An installation procedure of downloading the tuning data includes a search of the local television program. In order to accelerate the procedure, the page header of its teletext pages includes a code (.about.) indicating that the tuning data are incorporated in the television program.

Abstract: In a display device equipped with a picture-in-picture function, during controlling of the picture parameters of the main picture, one or several auxiliary pictures are presented on the screen, each having a certain combination of parameter settings. These may be preprogrammed, defined by a user, or automatically determined. The display device is provided with circuitry for transferring the parameter settings of one of the auxiliary pictures to the main picture. In a special embodiment, an auxiliary picture represents the parameter settings at the start of the picture parameter adjustment process. As a result, the old parameter settings may be compared with the new ones and, if so desired, may be reinstated in a simple manner.

Abstract: Transmitter station for transmitting, and receiver for receiving a plurality of television programs via respective transmission channels. A teletext page with tuning data (F) which are representative of the transmission channels used by the transmitter station is transmitted by means of one of the programs, for example a local television program. Moreover, further signal processing data are incorporated in the teletext page, which data are representative of the transmitted television programs, such as a station name (NAM), a system code (S) and a predetermined teletext page number (PDC). When the television receiver is tuned to a television program, the respective signal processing circuits are controlled by means of the corresponding signal processing data.
