Abstract

A system for broadcasting that includes a watermark payload.

Claims

1. A method for receiving information, the method comprising:

identifying whether the number of message fragments is more than zero;

receiving a 32 bit Cyclic Redundancy Check (CRC) included in a last fragment, wherein the 32 bit CRC contains a CRC value represented by CRC(x), wherein x is obtained by concatenating x₁, x₂, . . . , x_n in a case that the number of message fragment is more than zero.
