Module ts 

MPEG-TS packet parser and section reassembler — ITU-T H.222.0 §2.4 (= ISO/IEC 13818-1).

Structs

AdaptationField

Decoded adaptation field — full §2.4.3.4 layout including transport-private data and the adaptation-field extension sub-structure.

AdaptationFieldExtension

Adaptation-field extension (ISO/IEC 13818-1:2007 §2.4.3.5, adaptation_field_extension_flag == 1).

Ltw

legal_time_window field within the adaptation-field extension (ISO/IEC 13818-1:2007 §2.4.3.5, ltw_flag == 1).

Pcr

Program Clock Reference (ISO/IEC 13818-1:2007 §2.4.3.5): a 33-bit base on a 90 kHz clock plus a 9-bit extension on a 27 MHz clock.

SeamlessSplice

seamless_splice field within the adaptation-field extension (ISO/IEC 13818-1:2007 §2.4.3.5, seamless_splice_flag == 1).

SectionReassembler

Reassembles PSI/SI sections from TS packets on a single PID.

TsHeader

Parsed TS header — the 4-byte transport header fields.

TsPacket

Borrowed view into one 188-byte TS packet.

Enums

AdaptationFieldControl

2-bit adaptation_field_control field — ITU-T H.222.0 (08/2023) Table 2-5.

ScramblingControl

2-bit transport_scrambling_control field — ITU-T H.222.0 (08/2023) Table 2-4 (defines only 00 = not scrambled); DVB assigns 01/10/11 in ETSI TS 100 289 V1.1.1 §5.1 Table 1 (reserved, even CW, odd CW).

Constants

ADAPTATION_FLAG

ISO/IEC 13818-1 §2.4.3.3: byte 3 bit 5 = adaptation_field_control (bit 5 = 1 means adaptation present).

AF_PCR_FLAG

PCR present flag (bit 4 of adaptation field flags byte — §2.4.3.4).

CC_MASK

ISO/IEC 13818-1 §2.4.3.3: byte 3 bits [3:0] = 4-bit continuity_counter.

PAYLOAD_FLAG

ISO/IEC 13818-1 §2.4.3.3: byte 3 bit 4 = adaptation_field_control (bit 4 = 1 means payload present).

PID_MASK_HI

ISO/IEC 13818-1 §2.4.3.3: byte 1 bits [4:0] = 13-bit PID (upper 5 bits).

SCRAMBLING_MASK

ISO/IEC 13818-1 §2.4.3.3: byte 3 bits [7:6] = 2-bit scrambling control.

TS_PACKET_SIZE

Size of one MPEG-TS packet (ETSI EN 300 468 §3.2, ISO/IEC 13818-1 §2.4.3.2).

TS_SYNC_BYTE

Sync byte that every TS packet starts with (ISO/IEC 13818-1 §2.4.3.2).

Functions

extract_ts_payload

Extract the payload bytes from a raw 188-byte TS packet slice.

iter_packets

Iterate over all valid TS packets in a byte buffer.
