base_PID ---> STT (Time),
RRT (Censorship),
MGT (Guide management),
VCT (Channel Guide)
MGT ---> (PID_A,EIT[0],version_number),
(PID_B,EIT[1],version_number), etc,
(PID_X,RTT,version_number),
(PID_Y,RTT,version_number), etc,
(PID_1,Event ETT,version_number),
(PID_2,Event ETT,version_number), etc,
(PID_m,Channel ETT,version_number),
(PID_n,Channel ETT,version_number), etc.
Each EIT[i] is valid for 3 hours,
EIT[0] is always the current programming.
Other tables are described by descriptors,
such as Subtitle Descriptors.
VCT ---> (channel-A,source-id[0]),
(channel-B,source-id[1]), etc.
New VCTs can be sent with a new version number to update the programming in an EIT, then when the data is complete a new MGT is sent with an updated version_number for that EIT, updating the data.
