# dvb-si
ETSI EN 300 468 DVB Service Information parser **and builder**, plus the
MPEG-2 PSI tables it builds on, the DVB-allocated companion tables, and the
DSM-CC data carousel.
**Complete coverage: every allocated `table_id` in EN 300 468 V1.19.1
Table 2 (29 section types; 28 dispatched by `AnyTableSection` + the type-keyed MPE datagram view) and every allocated `descriptor_tag` in Table 12
(0x40–0x7F, 64 descriptors) is implemented**, each with a symmetric
`Parse` / `Serialize` pair and round-trip tests. Layouts are derived from the
ETSI specs (vendored in the repo and transcribed into reviewable markdown) and
validated against live broadcast captures.
## 4.0 API model
`dvb-si` 4.0 makes the PSI/SI layering explicit:
- Section parsers are named `*Section`: `PatSection`, `NitSection`,
`SdtSection`, `SitSection`, `EitSection`, and so on. Each value is exactly one
wire section and still borrows from the input bytes where possible.
- `AnyTableSection` dispatches one complete section by `table_id`. Demux events
expose this through `SectionEvent::table_section()`.
- `collect::SectionSetCollector` assembles every long-form multi-section table
using the common `section_number` / `last_section_number` fields. A completed
set owns the original section bytes and can be parsed generically:
`complete.table::<PatSection>()`.
- `collect::CompleteNit`, `CompleteBat`, `CompleteSdt`, and `CompleteEit` add
flattened logical-table views where that is more useful than a vector of
sections. Their descriptor loops are parsed through `AnyDescriptor` while the
raw descriptor-loop bytes remain available.
- `collect::EitCollector` handles the EIT schedule rule that spans table IDs
through `last_table_id`; ordinary section-number collection is not enough for
schedule EIT. EIT schedule sub-tables version independently, and the
collector exposes `clear()` / `retain_logical()` for long-running EPG pruning.
- `TableId` variants use Rust CamelCase names (`TableId::Pat`,
`TableId::NetworkInformationActual`, `TableId::MpeFec`), while section parser
types carry the `Section` suffix.
There are no 3.x compatibility aliases in 4.0. See
[`MIGRATION-4.0.md`](MIGRATION-4.0.md) for before/after examples.
## Section coverage
Every section parser: typed header fields, symmetric parse/serialize, round-trip
tested. Per the crate's zero-copy convention, descriptor loops and repeated
sub-structures borrow from the input bytes. Flat descriptor loops are
`DescriptorLoop` values that walk into typed descriptors; notes below call out
only tables that go further or deliberately keep a nested structure raw.

## DSM-CC data carousel
The `carousel` module types the download-protocol payloads carried inside
DSM-CC sections (ISO/IEC 13818-6 §7.2/§7.3 as profiled by DVB — TR 101 202,
TS 102 006 SSU, TS 102 809 object carousels):

| DII — DownloadInfoIndication | 0x1002 | ✅ full (typed module loop) |
| DDB — DownloadDataBlock | 0x1003 | ✅ full |
| `ModuleReassembler` | — | ✅ DDB → complete modules per DII geometry: version-aware, out-of-order tolerant, per-module + aggregate memory caps |
Validated **byte-exact** against a live French-TNT (M6 HbbTV) capture in the
test suite. BIOP object-carousel payloads above this layer are out of scope.
## Descriptors
**Every allocated `descriptor_tag` in EN 300 468 V1.19.1 Table 12
(0x40–0x7F) is implemented** — plus the MPEG-2 descriptors that matter in SI
context and the de-facto private logical_channel_descriptor. Each parses into
a typed struct with a symmetric serializer and round-trip tests; any
unallocated/unknown tag passes through as raw bytes (tag + payload preserved).
Per the crate's zero-copy convention, free-form byte fields (names, selector
tails) stay borrowed `&[u8]`; notes below only where a sub-structure is
deliberately kept raw.

### Extension descriptor registry (tag 0x7F)
The first payload byte (`descriptor_tag_extension`) selects a sub-descriptor
(EN 300 468 §6.4). A body is typed only when its syntax table is vendored
under `docs/`; everything else is preserved byte-exact as `Raw` and
round-trips losslessly.

The crate has been through five adversarial spec-audit rounds; fixture tests
run against real transponder captures.
## Demux in 10 lines
Feed 188-byte TS packets to [`SiDemux`]; it filters by PID, reassembles
sections, validates CRCs, follows the PAT to PMT PIDs, and version-gates so a
steady carousel emits each changed section only once. You get a `SectionEvent` per
**changed** section:
```rust
use dvb_si::demux::SiDemux;
use dvb_si::tables::AnyTableSection;
let mut demux = SiDemux::builder().build();
for packet in ts_packets { // each aligned 188-byte packet
for event in demux.feed(&packet) { // changed sections only
if let Ok(AnyTableSection::PatSection(pat)) = event.table_section() {
println!("PAT v{} on {}", event.version().unwrap_or(0), event.pid());
let _ = pat;
}
}
}
```
See [`examples/si_dump.rs`](examples/si_dump.rs) for a complete file-reading CLI
(`cargo run -p dvb-si --example si_dump -- file.ts [--json]`).
## Typed dispatch
You rarely match table_ids or descriptor_tags by hand. `AnyTableSection::parse`
dispatches a complete section to the right typed section parser; a section's descriptor-loop
field is a `DescriptorLoop` whose `.iter()` yields `AnyDescriptor` values (typed
where known, `Unknown` otherwise, never panicking — `parse_loop` does the same
for a free byte slice); and `DescriptorRegistry` lets you plug in private
descriptors at runtime. All are generated from a single declarative list so the
dispatcher can never drift from the implemented set.
```rust
use dvb_si::descriptors::AnyDescriptor;
for item in eit_event.descriptors.iter() { // DescriptorLoop::iter()
match item? {
AnyDescriptor::ShortEvent(se) => println!("{}", se.event_name.decode()),
AnyDescriptor::Unknown { tag, .. } => eprintln!("unknown 0x{tag:02X}"),
_ => {}
}
}
```

## Usage
```rust
use dvb_common::Parse;
use dvb_si::tables::sdt::SdtSection;
// `section_bytes`: one complete SDT section, e.g. from `SectionReassembler`.
let sdt = SdtSection::parse(section_bytes)?;
for service in &sdt.services {
println!("service_id = {}", service.service_id);
}
```
Collect all sections for a logical table before using table-wide fields. In a
live stream, collector errors are section-scoped: log/drop that input section
and keep feeding later sections unless your application chooses strict failure.
```rust
use dvb_si::collect::{CompletedEit, EitCollector, SectionSetCollector};
use dvb_si::demux::SiDemux;
use dvb_si::tables::eit;
use dvb_si::tables::nit::{self, NitSection};
let mut demux = SiDemux::builder().build();
let mut nit_sections = SectionSetCollector::new();
let mut eit_sections = EitCollector::new();
for event in demux.feed(&packet) {
match event.table_id() {
nit::TABLE_ID_ACTUAL | nit::TABLE_ID_OTHER => {
let collected = match nit_sections.push_section_with_pid(
Some(event.pid().value()),
event.bytes(),
) {
Ok(collected) => collected,
Err(error) => {
eprintln!("dropping bad SI section: {error}");
continue;
}
};
if let Some(complete) = collected {
let nit = complete.nit()?; // flattened logical NIT
let raw_sections = complete.table::<NitSection>()?; // generic section view
let _ = (nit, raw_sections);
}
}
eit::TABLE_ID_PF_ACTUAL..=eit::TABLE_ID_SCHEDULE_OTHER_LAST => {
let collected = match eit_sections.push_section_with_pid(
Some(event.pid().value()),
event.bytes(),
) {
Ok(collected) => collected,
Err(error) => {
eprintln!("dropping bad EIT section: {error}");
continue;
}
};
if let Some(done) = collected {
match done {
CompletedEit::PresentFollowing(set) => {
let eit = set.eit()?; // one p/f EIT section set
let _ = eit;
}
CompletedEit::Schedule(schedule) => {
for (table_id, version) in schedule.table_versions() {
println!("completed EIT schedule 0x{table_id:02X} v{version}");
}
for table in schedule.tables()? {
let _ = table.events;
}
}
}
}
}
_ => {}
}
}
// Long-running EPG collectors can prune application-defined old state.

- **Spec fidelity.** Every field in a section's syntax appears in the parsed struct.
- **Parse and construct.** Every parser has a symmetric serializer; round-trip is tested.
- **Zero-copy where possible.** Parsed types borrow from the input via `<'a>` lifetimes.
- **No magic numbers.** Every hex literal outside `#[cfg(test)]` is a named constant or enum.
## Features
Default: `chrono` (MJD+BCD → `DateTime<Utc>`), `ts` (TS packet +
`SectionReassembler`), `serde`.
`serde` is **Serialize-only** — for display/export (JSON via `serde_json`);
parsing FROM JSON is deliberately unsupported, re-parse from the wire bytes.
Optional (off by default):
`yoke` — `yoke::Yokeable` on every zero-copy view type plus an `Owned<T>`
wrapper, so you can own a parsed view past the input buffer's borrow (store it
in a struct field, a cache, a `watch`/broadcast channel, or send it across a
thread) without re-parsing or a hand-written mirror type:
```rust
use std::sync::Arc;
use dvb_si::{owned::Owned, tables::pmt::PmtSection};
use dvb_common::Parse;
let bytes: Arc<[u8]> = Arc::from(section); // own the section
let pmt: Owned<PmtSection<'static>> = Owned::try_new(bytes, |b| PmtSection::parse(b))?;
let view: &PmtSection = pmt.get(); // no re-parse, no lifetime
```
```toml
dvb-si = { version = "4.0", default-features = false } # tight build
```
