Struct Cea608Decoder 

pub struct Cea608Decoder { /* private fields */ }

Available on crate feature decode only.

CEA-608 (line-21) caption decoder.

Feed it CcTriplets (or raw byte pairs) of the 608 fields; read decoded text per channel via channel_text / screen.

use dvb_cc::decode::{Cea608Decoder, Cea608Channel};
let mut dec = Cea608Decoder::new();
// RCL, PAC row 15, "HI", EOC — a pop-on caption on CC1 (field 1).
dec.push_pair(false, 0x14, 0x20); // RCL (field 1 → CC1)
dec.push_pair(false, 0x14, 0x20); // doubled control — ignored
dec.push_pair(false, 0x14, 0x70); // PAC row 15 indent 0 (field 1)
dec.push_pair(false, b'H', b'I');
dec.push_pair(false, 0x14, 0x2F); // EOC → flip
assert_eq!(dec.channel_text(Cea608Channel::Cc1), "HI");

Implementations

impl Cea608Decoder

pub fn new() -> Self

A new decoder.

pub fn push_triplets<'a, I>(&mut self, triplets: I)

where I: IntoIterator<Item = &'a CcTriplet>,

Feed the decoder the 608 (line-21) triplets of a crate::CcData.

pub fn push_pair(&mut self, field2: bool, b1: u8, b2: u8)

Feed one raw 608 byte pair. field2 = false ⇒ field 1 (cc_type 0); field2 = true ⇒ field 2 (cc_type 1). Bytes may carry parity in b7.

pub fn screen(&self, channel: Cea608Channel) -> &Cea608Screen

The displayed screen for a channel.

pub fn mode(&self, channel: Cea608Channel) -> Cea608Mode

The current mode for a channel.

pub fn channel_text(&self, channel: Cea608Channel) -> String

The decoded displayed text for a channel.

Trait Implementations

impl Clone for Cea608Decoder

fn clone(&self) -> Cea608Decoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cea608Decoder

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

Formats the value using the given formatter.

impl Default for Cea608Decoder

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Cea608Decoder

impl PartialEq for Cea608Decoder

fn eq(&self, other: &Cea608Decoder) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
