Struct MonochromeDataField 

pub struct MonochromeDataField<'a> {
    pub first_segment: bool,
    pub last_segment: bool,
    pub field_parity: bool,
    pub line_offset: u8,
    pub first_pixel_position: u16,
    pub samples: &'a [u8],
}

Monochrome 4:2:2 luminance-sample data field — ETSI EN 301 775 §4.9.1, Table 12 (data_unit_id 0xC6).

Unlike the other units this packs its first byte as [7] first_segment_flag, [6] last_segment_flag, [5] field_parity, [4:0] line_offset (no 2-bit reserved prefix), then a 16-bit first_pixel_position, an 8-bit n_pixels, and n_pixels luminance Y_value bytes.

Fields

first_segment: bool

first_segment_flag (1 for the first segment of a line).

last_segment: bool

last_segment_flag (1 for the last segment of a line).

field_parity: bool

field_parity (1 first field, 0 second field).

line_offset: u8

line_offset (5 bits, 7..=23 valid; coded per Table 13).

first_pixel_position: u16

first_pixel_position (16 bits, 0..=719): position of the first coded luminance sample of this segment.

samples: &'a [u8]

Y_value luminance samples; n_pixels is samples.len() (1..=251).

Implementations

impl<'a> MonochromeDataField<'a>

pub fn serialized_len(&self) -> usize

Bytes this data field occupies (the data_unit_length).

pub fn parse(data: &'a [u8]) -> Result<Self>

Parse exactly one monochrome data field from data (data is the data-unit body of data_unit_length bytes). n_pixels is taken from the wire and the sample slice is borrowed from data.

pub fn serialize_into(&self, out: &mut [u8]) -> Result<usize>

Serialize into out, returning the number of bytes written. n_pixels is derived from samples.len().
