Abstract
A method of inserting meta-data into a physical layer framing structure of a Digital Video Broadcast Satellite-Generation 2 (DVB-S2) comprising encoding meta-data and an original carrier signal using an encoder, the original carrier signal having a pilot sequence, replacing, by a meta-data insertion device, at least a portion of the pilot sequence with at least a portion of the meta-data to form a meta-pilot carrier signal, modulating, using a modulator, the meta-pilot carrier signal to form a modulated meta-pilot carrier signal, and transmitting, using a transmitting device, the modulated meta-pilot carrier signal. Additionally, the meta-data may be inserted by a meta-data insertion device into at least a portion of the XFECFRAME structure when dummy-PL Frames are available when VCM and ACM operation is used.
