Method for gateway signaling for MISO operation and apparatus therefor

A broadcast gateway signaling method, comprising:

• generating structure data, which includes first data fields for all of transmitters used for Multiple-Input Single-Output (MISO);
• generating per-transmitter data, which includes second data fields only for one transmitter of the transmitters;
• generating a timing and management packet, which includes the structure data and the per-transmitter data;
• and
• transmitting the timing and management packet to the transmitters through a Studio-to-Transmitter Link (STL),
• wherein the timing and management packet includes a structure data part including the structure data and a per-transmitter data part including the per-transmitter data,
• wherein the structure data includes a first MISO field representing the number of transmitters used for the MISO,
• wherein the per-transmitter data includes a second MISO field representing the transmitter coefficient index of the one transmitter, and
• wherein the first MISO field is a 2-bit field, and is set based on the number of different MISO filter codes in use within a Single-Frequency Network (SFN).
