In the DVB-C standard, each service's program broadcasts a total of 16 tables of table 0x50-0x5f (0x60-0x6f),
Each table can transmit 4 days of programs, which can handle 64 days of programs, each of which has 256 segments,
The maximum length of each segment is 4096byte, which is generally transmitted in operation, and the maximum amount of data is
4k * 256 * 2 = 2MBYTE, according to the standard, if the transmit frequency of EIT Schedule is 6 seconds, then the speed is the maximum rate
2MBYTE / 6 * 8 = 3MBPS, if only basic information is transmitted in EIT, the amount of data can be reduced to gradual
1/15 = 200kbps
