Abstract
A device for receiving, storing and displaying television images. The device comprises a buffer (2) for storing television images. Television images having a first frame frequency are received at an input (4). Television images having a second frame frequency are supplied at an output (6). The buffer is adapted to store and read television images. A number of X consecutive television images stored in the buffer lie between a television image read at a given instant from the buffer and a television image stored at substantially the same instant. In a first state, X increases with time. In a second state, X decreases with time. The device further comprises a control device (12) for generating a first control signal (14) for bringing the device from the first to the second state, and a second control signal (16) for bringing the device from the second to the first state. This device makes it possible to start to watch television images simultaneously at the instant of their reception, while television images received at a later instant and not yet displayed, for example, a block of commercials, can be watched in an accelerated manner.
