20090265751Reception of ancillary 8VSB signals controlled responsive to information signaling version of broadcast standard being used - Modifications to the system of broadcasting robustly coded ancillary transmissions to mobile and portable receivers of 8VSB digital television signals include version information as part of signal transmissions besides those made specifically to support an electronic service guide (ESG). This version information indicates what version of broadcast standard the signals complied with when transmitted. Such modifications allow such a receiver to determine whether it has the capability to process received ancillary transmissions usefully, without the receiver having to refer to an ESG derived from robustly coded ancillary transmissions that have been fully decoded. Such determination allows the receiver to avoid decoding of the robustly coded ancillary transmissions or to curtail such decoding after partial completion thereof, which reductions in decoding procedures reduce battery drain in battery-powered mobile and portable receivers. A receiver designed to respond to these modifications to the system of broadcasting is much less likely to malfunction owing to the ESG signal containing error when transmitted or accruing error owing to corruption during transmission.10-22-2009
