Struct ServiceDescriptionTable

    pub other_transport_stream: bool,
    pub version_number: u8,
    pub current_next_indicator: bool,

}

Parsed DVB Service Description Table (ETSI EN 300 468 §5.2.3 Table 5).

The SDT is a DVB Service Information table carried on the fixed PID SDT_PID (0x0011). Sections describing the actual TS use table_id == SDT_ACTUAL_TABLE_ID (0x42); sections describing other TSs use SDT_OTHER_TABLE_ID (0x46). It shares the 8-byte long-form PSI section header (parsed and CRC-verified the same way as PAT/PMT), then carries original_network_id (16 bits) plus one reserved byte, then a loop of SdtService entries, then the CRC.

transport_stream_id is taken from the table_id_extension slot per §5.2.3. The service loop’s per-service descriptor blocks most commonly carry the DVB service_descriptor (tag 0x48), which the crate’s descriptor decoder lifts into crate::descriptor::ServiceDescriptor — the source of a service’s human-readable name and provider.

Fields

transport_stream_id: u16

transport_stream_id (from table_id_extension).

other_transport_stream: bool

true when the section’s table_id was 0x46 (describes another TS); false for 0x42 (the actual TS carrying the SDT).

version_number: u8

5-bit version_number.

current_next_indicator: bool

current_next_indicator.

section_number: u8

section_number.

last_section_number: u8

last_section_number.

original_network_id: u16

original_network_id.

services: Vec<SdtService>

Service entries carried in this section.

Implementations

impl ServiceDescriptionTable

pub fn parse(section: &[u8]) -> Result<Self, TsError>

Parse a single SDT section. The slice must run from table_id through the CRC trailer (i.e. the pointer_field has already been skipped). Accepts both the actual-TS (0x42) and other-TS (0x46) table_ids.

Trait Implementations

impl Clone for ServiceDescriptionTable

fn clone(&self) -> ServiceDescriptionTable

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ServiceDescriptionTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ServiceDescriptionTable

fn default() -> ServiceDescriptionTable

Returns the “default value” for a type.
