Abstract:
A recording arrangement for recording a digital video signal in tracks on a record carrier, the arrangement comprising:input means for receiving the digital video signal;trick play signal generating means coupled to said input means for deriving a trick play signal from the digital video signal;error correction encoding means for carrying out an error correction encoding step on the digital video signal and the trick play signal; andwriting means for writing error correction encoded data in the tracks,characterized in that the error correction encoding means comprises:a first error correction encoding stage coupled to an output of the trick play signal generating means for carrying out a first error correction encoding step on a block of trick play data comprised in the trick play signal, the first error correction encoding stage adding first parity words to the block of trick play data to form an error correction encoded block of trick play data; anda second error correction encoding stage coupled to said input means and to an output of said first error correction encoding stage for carrying out a second error correction encoding step on a block of data comprised in the digital video signal from said input means, and on the error correction encoded block of trick play data from said first error correction encoding stage, the second error correction encoding stage combining the block of data of the digital video signal and the error correction encoded block of trick play data to form a composite block of data, said second error correction encoding stage further adding second parity words to the composite block of data to form an error correction encoded composite block of data, wherein said writing means writes in the tracks error correction encoded composite blocks of data formed by said second error correction encoding stage.
