DEFINITION

Classification: 714/FOR.191

Forward error correction by tree code (e.g., convolutional):

Foreign art collections including subject matter in which information bits are encoded to generate a plurality of check bits, each check bit is generated as a function of a different plurality of information bits and is interspersed among the information bits at predetermined intervals with no natural beginning point or ending point (i.e.., there is no length restriction for the encoded data).
