摘要： Input values are data encoded for improved signal characteristics (e.g., limited maximum run length and limited cumulative DC-offset) so as to form "data codewords," and then a number of the data codewords, collectively referred to as a block, are error protection encoded, preferably using a conventional linear and systematic forward error control ("FEC") code, to yield an FEC code block. Preferably, an FEC code block is formed by generating a number of check bits or FEC bits equal to the number of data codewords in the block, and then concatenating one FEC bit and its binary complement with each data codeword, so that one FEC bit and its complement is interposed between each successive codeword.

摘要： An overshoe for a shoe whose soles have a plurality of extending spikes, cleats or similar surface engaging elements to protect surfaces from being disturbed or damaged by contacting such elements includes a two-layered substantially flat sole with a toe hold and a heel retaining member. The two-layered sole includes a soft upper layer interconnected to a hard lower layer, and is formed in an oblong generally rectangular configuration that is oversized relative to the soles of conventionally sized spiked sport shoes. The lower layer is sufficiently firm or tough enough to resist puncturing by spikes or cleats extending from a sole of a covered shoe, and is preferably made of hard rubber, so golf spikes will not penetrate the sole and scuff or mark putting greens. The upper layer is soft or flexible to accommodate depressions formed from spikes or cleats extending from a sole of a covered shoe, and is preferably made of soft rubber or foam. The oversized oblong two-layered sole possesses a particular color, such as black, white or others. The toe hold is formed in conjunction with a front portion of the lower layer. The heel retaining member includes two relatively elastic bands connected to a leather patch.
