Abstract: First and second transmitters transmit signals communicating the same information, e.g., program segment, but at different times. Different carriers may, but need not be, used by the different transmitters. If a wireless terminal can not recover broadcast segment information from one carrier, the wireless terminal can switch to another transmitter and recover the information, e.g., on another carrier, since the broadcasts are intentionally offset in time. In some embodiments, the timing is offset such that a single channel receiver is able to recover signals corresponding to the same program segment from two sources, and perform a decoding and information recovery using input from both sources, where recovery using input from a single source is not possible. Symbol level timing synchronization of base stations is not required thereby allowing for simpler implementations and/or lower overhead, as compared to systems which require base stations to be synchronized to the symbol timing level.
