Typed body for descriptors this module decodes.

Variants

VideoStream(VideoStreamDescriptor)

0x02 video_stream_descriptor (§2.6.2).

AudioStream(AudioStreamDescriptor)

0x03 audio_stream_descriptor (§2.6.4).

Hierarchy(HierarchyDescriptor)

0x04 hierarchy_descriptor (§2.6.6) — links one program element to its embedded base layer for hierarchically-coded video / audio / private streams (Table 2-43).

Registration

0x05 registration_descriptor (§2.6.8). format_identifier is a 4-byte ASCII code (e.g. b"HDMV" on Blu-ray) plus optional additional bytes whose semantics are scoped to the FOURCC.

Fields

format_identifier: [u8; 4]

additional_identification_info: &'a [u8]

DataStreamAlignment(DataStreamAlignmentDescriptor)

0x06 data_stream_alignment_descriptor (§2.6.10).

TargetBackgroundGrid(TargetBackgroundGridDescriptor)

0x07 target_background_grid_descriptor (§2.6.12) — describes a grid of unit pixels projected onto the display area, against which a paired video_window_descriptor places the stream’s window (Table 2-49).

VideoWindow(VideoWindowDescriptor)

0x08 video_window_descriptor (§2.6.14) — places the stream’s display window on the grid defined by its paired target_background_grid_descriptor (Table 2-50).

Ca(CaDescriptor<'a>)

0x09 CA_descriptor (§2.6.16) — Conditional Access PID + system.

Iso639Language(Vec<Iso639Language>)

0x0A ISO_639_language_descriptor (§2.6.18).

SystemClock(SystemClockDescriptor)

0x0B system_clock_descriptor (§2.6.20).

MultiplexBufferUtilization(MultiplexBufferUtilizationDescriptor)

0x0C multiplex_buffer_utilization_descriptor (§2.6.22).

Copyright(CopyrightDescriptor<'a>)

0x0D copyright_descriptor (§2.6.24).

MaximumBitrate(MaximumBitrateDescriptor)

0x0E maximum_bitrate_descriptor (§2.6.26).

SmoothingBuffer(SmoothingBufferDescriptor)

0x10 smoothing_buffer_descriptor (§2.6.30).

Std(StdDescriptor)

0x11 STD_descriptor (§2.6.32).

Ibp(IbpDescriptor)

0x12 IBP_descriptor (§2.6.34) — GOP-structure hints for the associated video elementary stream (Table 2-61).

AvcVideo(AvcVideoDescriptor)

0x28 AVC_video_descriptor (§2.6.64).

HevcVideo(HevcVideoDescriptor)

0x38 HEVC_video_descriptor (Amd. 3 §2.6.95).

Service(ServiceDescriptor<'a>)

0x48 service_descriptor — DVB SI extension (ETSI EN 300 468 §6.2.33 Table 88). Carried in the SDT service loop; names the service plus its provider in text form.

ShortEvent(ShortEventDescriptor<'a>)

0x4D short_event_descriptor — DVB SI extension (ETSI EN 300 468 §6.2.37 Table 93). Carried in the EIT event loop; names the event plus a short text description, both tagged with a language code.

Raw

Unrecognised tag — payload bytes preserved verbatim.

Trait Implementations

impl<'a> Clone for DescriptorBody<'a>

fn clone(&self) -> DescriptorBody<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for DescriptorBody<'a>

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

Formats the value using the given formatter.
