Expand description

Stream type coding — Rec. ITU-T H.222.0 (06/2021) Table 2-34.

Identifies the elementary-stream type carried in the associated PID. Values 0x80–0xFF are user private; only well-established entries cited to their own specs are named — the rest fall through to UserPrivate.

§Examples

use dvb_si::tables::pmt::StreamType;

assert_eq!(StreamType::from_u8(0x02).name(), "MPEG-2 Video");
assert_eq!(StreamType::from_u8(0x1B).to_u8(), 0x1B); // H.264, lossless round-trip

A parsed PmtStream.stream_type is already a StreamType — match on it directly.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations§

Source§

impl StreamType

Source

pub fn from_u8(v: u8) -> Self

Decode from the wire byte. Every byte maps to a variant (lossless).

Source

pub const fn to_u8(self) -> u8

Encode to the wire byte. Inverse of from_u8.

Source

pub fn is_video(self) -> bool

Returns true if this stream_type carries a video elementary stream.

Note on PesPrivateData (0x06): this stream_type alone does not identify the payload — AC-3, H.264, DVB subtitle, teletext, and others all share 0x06 and are disambiguated by component/registration descriptors per ETSI TS 101 154. is_video returns false for PesPrivateData; callers must inspect the ES_info descriptor loop to resolve the actual content type.

Source

pub fn is_audio(self) -> bool

Returns true if this stream_type carries an audio elementary stream.

Note on PesPrivateData (0x06): this stream_type alone does not identify the payload — AC-3 carried over DVB uses 0x06 with an AC-3/enhanced AC-3 descriptor per ETSI TS 101 154. is_audio returns false for PesPrivateData; callers must inspect the ES_info descriptor loop to resolve the actual content type.

Source

pub fn is_subtitle(self) -> bool

Returns true if this stream_type unambiguously carries subtitle/text content.

Only Iso14496_17Text (0x1D, ISO/IEC 14496-17 timed text) is unambiguously identified as subtitle/text by the stream_type byte alone.

Note on PesPrivateData (0x06): DVB bitmap subtitles (ETSI EN 300 743) and DVB teletext (ETSI EN 300 472) both use stream_type 0x06 and are identified by subtitling / teletext descriptors in the ES_info loop per ETSI TS 101 154. is_subtitle returns false for PesPrivateData; callers must inspect the ES_info descriptor loop to resolve the actual content type.

Source

pub fn is_data(self) -> bool

Returns true if this stream_type carries data, private sections, signalling, or metadata — i.e. neither video, audio, nor subtitle.

Note on PesPrivateData (0x06): this stream_type is shared by many DVB content types — AC-3 audio, E-AC-3, DVB subtitles, teletext, and others — all identified via descriptors per ETSI TS 101 154. This predicate conservatively classifies 0x06 as data/unknown. Callers that need to classify 0x06 streams must inspect the ES_info descriptor loop.
