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
