Struct AtcPacket 

pub struct AtcPacket {
    pub atc_type: AtcType,
    pub timecode: Timecode,
    pub user_bits: u32,
    pub continuity_count_valid: bool,
    pub continuity_count: u8,
    pub valid: bool,
}

Ancillary Timecode (ATC) packet for SDI embedding.

This struct holds a timecode value packaged for insertion into the ancillary data space of an SDI signal.

Fields

atc_type: AtcType

Whether this is LTC-ATC or VITC-ATC.

timecode: Timecode

The timecode value.

user_bits: u32

User bits (32 bits of user-defined data).

continuity_count_valid: bool

Whether continuity counter is valid.

continuity_count: u8

Continuity counter (0-127).

valid: bool

Whether this packet contains valid data.

Implementations

impl AtcPacket

pub fn new(atc_type: AtcType, timecode: Timecode) -> Self

Create a new ATC packet with the given timecode.

pub fn ltc(timecode: Timecode) -> Self

Create an LTC-ATC packet.

pub fn vitc(timecode: Timecode) -> Self

Create a VITC-ATC packet.

pub fn with_user_bits(self, user_bits: u32) -> Self

Set user bits.

pub fn with_continuity(self, count: u8) -> Self

Set continuity counter.

pub fn to_sdi_words(&self) -> Vec<u16>

Serialize the ATC packet to 10-bit SDI words (as u16).

Returns the ancillary data packet words including ADF, DID, SDID, DC, user data, and checksum per SMPTE ST 291.

pub fn from_sdi_words(words: &[u16]) -> Result<Self, TimecodeError>

Parse an ATC packet from 10-bit SDI words.

Errors

Returns error if the packet is malformed, checksum fails, or the DID/SDID is not recognized as ATC.

Trait Implementations

impl Clone for AtcPacket

fn clone(&self) -> AtcPacket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AtcPacket

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

Formats the value using the given formatter.
