Detailed Description

Definitions of the TSDuck internal messaging protocol.

Note that none of the assigned values overlap with the message_type values which are defined in DVB Simulcrypt protocols. They are allocated in the "user defined" range. Thus, a generic TLV message parser can be use for both DVB and TSDuck interfaces.

Definition of messages:

MSG_LOG_SECTION
Contains one section.
    Parameter      Count
    PRM_PID        0-1
    PRM_TIMESTAMP  0-1
    PRM_SECTION    1
 
MSG_LOG_TABLE
Contains one complete table (no missing section).
    Parameter      Count
    PRM_PID        0-1
    PRM_TIMESTAMP  0-1
    PRM_SECTION    1-n
 
MSG_ECM
Contains the section payload of a "fake" ECM as generated by tsecmg.
    Parameter           Count
    PRM_CW_EVEN         0-1
    PRM_CW_ODD          0-1
    PRM_ACCESS_CRITERIA 0-1
 
MSG_ERROR
Contains an error code.
    Parameter           Count
    PRM_ERROR_CODE      1

Definition of parameters:

PRM_PID
    A 2-byte PID value.
 
PRM_TIMESTAMP
    A timestamp identifying the occurence of the event. Same format
    as the activation_time in the EIS<=>SCS DVB Simulcrypt protocol:
       year       2 bytes
       month      1 byte
       day        1 byte
       hour       1 byte
       minute     1 byte
       second     1 byte
       hundredth  1 byte
 
PRM_SECTION
    A complete section, including header.
 
PRM_ERROR_CODE
    A 2-byte error code.
 
PRM_CW_EVEN
PRM_CW_ODD
PRM_ACCESS_CRITERIA
    Binary data as sent by the SCS. Included in "fake" ECM's ty tsecmg.
