Abstract
A data slicer for data transmitted during given lines of a television signal comprises a subtractor (3) to which the input data is applied at a first input (2) and a slicing level is applied at a second input (8). The sliced data is fed to an offset generator (5) which generates the slicing level. A transition detector (11) controls a switch (13) which causes the offset generator (5) to generate either a fixed offset derived from a history of the received data amplitude or a zero offset. The arrangement is such that for teletext data a fixed offset is applied at the start of a line, zero offset is applied during the clock run in period, and a fixed offset is then used to slice the NRZ data. For biphase data such as VPS or PAL plus signalling data a zero offset is applied for the duration of the data packet.
