Enum ScramblingControl 

#[non_exhaustive]
pub enum ScramblingControl {
    NotScrambled,
    Reserved,
    EvenKey,
    OddKey,
}

2-bit transport_scrambling_control field — ITU-T H.222.0 (08/2023) Table 2-4 (defines only 00 = not scrambled); DVB assigns 01/10/11 in ETSI TS 100 289 V1.1.1 §5.1 Table 1 (reserved, even CW, odd CW).

MPEG-2 leaves 01/10/11 as user-defined; DVB’s common-scrambling convention assigns 10 = even control word, 11 = odd control word, 01 = reserved for future DVB use. The field lives in the TS header and is never applied to the header itself — only to the packet payload.

Variants (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.

NotScrambled

00 — not scrambled. The only MPEG-2-defined value (H.222.0 Table 2-4).

Reserved

01 — reserved for future DVB use (ETSI TS 100 289 V1.1.1 §5.1 Table 1).

EvenKey

10 — TS packet payload scrambled with the even control word (DVB common scrambling, ETSI TS 100 289 V1.1.1 §5.1 Table 1).

OddKey

11 — TS packet payload scrambled with the odd control word (DVB common scrambling, ETSI TS 100 289 V1.1.1 §5.1 Table 1).

Implementations

impl ScramblingControl

pub fn from_bits(bits: u8) -> Self

Decode from the 2-bit transport_scrambling_control value (masked to [1:0]).

pub fn to_bits(self) -> u8

Encode as the 2-bit transport_scrambling_control field value ([1:0]).

The returned byte is in the range 0x00–0x03; the caller shifts it into position within the TS header byte 3 (H.222.0 Table 2-4).

pub fn name(&self) -> &'static str

Short label for this value, per the #204 convention.
