Abstract
A teletext decoder is provided which is suitable for decoding a packet of teletext signal to generate a teletext. The teletext decoder includes an error judgment device for judging the accuracy of a plurality of sliced bits, and correcting an error occurrence bit in the sliced bits on the basis of a plurality of sampling points and a slicer level when the plurality of sliced bits are incorrect.
Claims13
A teletext decoder, for decoding a packet from a teletext signal to generate a teletext, comprising:
- a sampling module, for sampling the packet according to a sampling clock signal to thereby generate a plurality of sampling points;
- a slicer level calculator, for acquiring a slicer level according to the packet and generating a plurality of sliced bits according to the sampling points and the slicer level;
- and
- an error judgment device, for determining whether the sliced bits are correct and correcting an error occurrence bit in the sliced bits by the sampling points and the slicer level when the sliced bits are incorrect.
