the max byte size of DVB SI EIT section is 4096 while the transport stream packet's payload max size is 188. so how to map DVB SI EIT section into TS packet?
payload_unit_start_indicator – The payload_unit_start_indicator is a 1-bit flag which has normative meaning for
Transport Stream packets that carry PES packets (refer to 2.4.3.6) or PSI data (refer to 2.4.4).
When the payload of the Transport Stream packet contains PSI data, the payload_unit_start_indicator has the following
significance: if the Transport Stream packet carries the first byte of a PSI section, the payload_unit_start_indicator value
shall be '1', indicating that the first byte of the payload of this Transport Stream packet carries the pointer_field. If the
Transport Stream packet does not carry the first byte of a PSI section, the payload_unit_start_indicator value shall be '0',
indicating that there is no pointer_field in the payload. Refer to 2.4.4.1 and 2.4.4.2(pointer_field). This also applies to private streams of
stream_type 5 (refer to Table 2-29).
For null packets the payload_unit_start_indicator shall be set to '0'.
