4.1 Overview
For locating SRM streams from the SDT, the present document defines two mechanisms. The first mechanism allows to locate a DVB Service the Components of which only convey SRM data. Consequently such a service shall be signalled as being of the type "SRM Service". The second mechanism allows to locate a Component convey...

4.1 Radio Interface Layering
As described in ETSI TS 102 744-1-3 [6], the satellite communication protocol is considered as a number of communication layers, as follows: • Adaptation Layer (AL); • Bearer Connection Layer (BCn); • Bearer Control Layer (BCt); and • Physical Layer (L1). The satellite radio interface protocol stack is designed to seam...

4.2 Bearer Control Layer
The Bearer Control Layer includes at least one Bearer Control process, which operates over and manages specific Bearer Types (physical layer specifications for the Shared Access Bearer). The detailed behaviour of the Bearer Control process, and the interface definitions for peer-peer communication of the Bearer Control...

4.3.1 Presentation
The following conventions are applied throughout the present document: • In the ASN.1 notation, variable names are always in lower case letters with hyphenation used to improve readability (e.g. ret-bct-pdu-header). Data Types in the ASN.1 always start with an upper case letter and may contain additional upper case let...

Fields shown as Reserved BITSTRING (..) in the ASN.1 structures shall be set to zero by the sender and shall be ignored by the receiver. Values not allocated in Distinguished Value Lists shall not be used by the sender and shall be ignored by the receiver. NOTE 1: Distinguished Value Lists of type Integer are being use...

The ASN.1 presentation provided in the present document for this interface specification is normative. The encoding rules used for this interface specification are non-standard, using a structured form of packed encoding that ensures efficient packing of each encoded BCtPDU while maintaining preservation of octet bound...

5.1.1 Return Bearer Control PDU Structure (RetBCtPDU)
The Return Bearer Control PDU structure depends on the Return Bearer type used on the Physical Layer as follows. For all Bearer Types except R80T0.5Q and R80T1Q, each RetBCtPDU consists of a Return BCtPDU Header, an optional sequence of one or more Bearer Control Signalling Data Units (BCtSDUs), an optional BCtPayload ...

5.1.3.1 RetBCtPDU Header Structure Type 1
The Bearer Control PDU Header Type 1 shall be used for all BCtPDUs except for the first BCtPDU sent in a Return Block structure (see ETSI TS 102 744-2-2 [9]) using Return Bearer Types R80T0.5Q or R80T1Q. This Bearer Control PDU Header has the following structure: RetBCtPDUHeader ::= SEQUENCE { bct-sdu-follows BOOLEAN, ...

The Bearer Control PDU Header Type 2 shall be used for the first BCtPDUs sent in a Return Block structure (see ETSI TS 102 744-2-1 [8]) using Return Bearer Types R80T0.5Q or R80T1Q. This Bearer Control PDU Header has the following structure: LdrBCtPDUHeader ::= SEQUENCE { bct-sdu-follows BOOLEAN, length-present BOOLEAN...

c685b69cc7e892f5b479b9df06e20b36
102 744-3-1
5.1.5.1 Bct-sdu-follows
The BOOLEAN variable bct-sdu-follows indicates, when set to value '1', that a BCtSDU follows the header; else a BCnPDU follows the header.
c685b69cc7e892f5b479b9df06e20b36
102 744-3-1
5.1.5.2 Length-present
The BOOLEAN variable length-present indicates the presence of a length field within the header when set to the value '1'.

102 744-3-1
5.1.5.3 Length
The length field, if present, is an eight-bit value which specifies the content length of the PDU from the end of the header to the start of the CRC field. If the length field is absent, the PDU either fills the remaining space in a physical layer block or slot (up to a maximum content length of 256 octets), or is a PD...

5.1.5.4 BCtPDUAddrType
The variable bct-pdu-addr-type is a two-bit field which is used in the to-UE direction only, and determines the addressing mechanism used for the BCtPDU. The variable is encoded as follows and as shown in Table 5.1: BCtPDUAddrType ::= INTEGER { broadcast (0), tbcn-id (1), comsig-or-ext-addr (2) -- reserved (3) } (0..3)...

102 744-3-1
5.1.5.5 Comsig-or-ext-addr-present
The BOOLEAN variable comsig-or-ext-addr-present determines the choice of the addressing mechanism of the BCtPDU. If this variable is set to '1', then the sequence comsig-type-and-address or ext-addr-type-and-address is present in the header, else tbcn-id is present. ETSI ETSI TS 102 744-3-1 V1.1.1 (2015-10) 27
