• the signal combination unit 19 replaces said uninteresting part of the first TV signal by said second TV signal block applied by the storage device 17 to obtain a composite TV signal.
• the composite TV signal is reproduced on a display device coupled to the TV signal receiver.
• the signal combination unit 19 may be adapted to replace the whole images in the first TV signal by the images of the second TV signal block, but could also be adapted to generate a composite signal comprising images, whereby the images of the second TV signal block replace only a part of the images of the first TV signal, for example, as a picture in picture image. By doing so, the user is able to increase the viewing pleasure.

Characteristics of a second TV signal block may be the theme, the subject, the kind of commercial or the product promoted. The second detector 35 may be adapted to detect more then one characteristic of a second TV signal block. The detected characteristic is applied to the unit 33. The unit 33 is further adapted to count the number of times a second TV signal block with a determined characteristic is detected by the second detector 35. These counting values do give information about the number of times that the user could view a second TV signal block with a specific characteristic. Further the unit 33 counts the number of times the reading of a second TV signal block with said determined characteristic is stopped by receiving the second command from the user.

• the indication signal generated by the third detector 29 is applied to the reading unit 47.
• the reading unit is adapted to inhibit reading the first TV signal from the second memory 45 in response to said indication signal and to resume reading the first TV signal, when no longer a second TV signal block is read from the first memory, which is indicated by the first and second control signal. In this manner, a second TV signal block read from the memory can always be displayed completely on the TV screen, without missing the beginning part of a TV program received while the second TV signal block was outputted.
• Said event happens when the duration of a second TV signal block is longer than the remaining time of an interruption in the first TV signal.
• the third detector 39 detects the end of an interruption in the signal supplied to the signal combination unit, while a second TV signal block is supplied to the signal combination unit 19, the reading unit 47 inhibits reading the first TV signal from the second memory 45.
