Claim One:
1. A method for improving signal demodulation in an Advanced Television Systems Committee (ATSC) receiver device, comprising: receiving a multiplexed ATSC signal including an ATSC service and at least one ATSC-Mobile/Handheld (ATSC-M/H) slot; obtaining an ATSC-M/H training sequence 2 (TR2) from the received multiplexed ATSC signal based on a symbol count during the at least one ATSC M/H slot; correlating symbols from two halves of the obtained TR2; determining whether a correlation of the symbols of the two halves of the obtained TR2 satisfies a threshold condition; starting a counter to obtain an ATSC-M/H training sequence 1 (TR1) when the correlation of the symbols of the two halves of the obtained TR2 satisfies the threshold condition; and locking onto the ATSC service using the obtained TR1 and the obtained TR2.
