Abstract
A method of storing, in memory, table data. The table data has a packet ID (PID), a Table ID, and a Current/Next Indicator, a section number, and a version number. The first step in the method is specifying the PID ID, the Table ID, and the Current/Next Indicator. The next step is initializing the section number in a table section header to filter to `0`. Then, each table section is checked as received to determine if the table section is the last table section for the table. This is indicated in the table section header. If this is the last table section of the table the version number field is incremented, and the section number field is set to `0`. If, however, the section is not the last section, the section number is incremented, the next section of the table is incremented, and the next section of the table is stored in memory.
