Receiver receiving a signal including physical layer frames, and including a convolutional deinterleaver and a deinterleaver selector

A method, comprising:

• receiving a frame including a sequence of symbols, being mapped on a Quadrature Amplitude Modulation (QAM) constellation, and interleaved in accordance with a convolutional interleaving, the received sequence of symbols being divided into blocks of forward error-correction encoded data,
• receiving signaling data including a number of symbols indicating a start position of a block of forward error-correction encoded data that results after the convolutional interleaving has been performed for the frame, the received signaling data being applied to the frame,
• deinterleaving the received sequence of symbols into an output sequence, in accordance with a plurality n of delay lines, a k-th delay line having k delay elements with k varying from 0 to n−1, and
• decoding the output sequence in accordance with the signaled number of symbols indicating the start position of the block of forward error-correction encoded data that results after the convolutional interleaving has been performed for the frame.
