  Two-dimensional (2D) convolutional codes are a generalization of (1D)
convolutional codes, which are very appropriate for transmission over an
erasure channel. In this paper, we present a decoding algorithm for 2D
convolutional codes over this kind of channel by reducing the decoding process
to several decoding steps with 1D convolutional codes. Moreover, we provide
constructions of 2D convolutional codes that are specially taylored to our
decoding algorithm.
