Accepts the authenticated Player heartbeat. Optional Linux Display Control fields report detected providers, independent capabilities, display power observations, and policy state. They do not determine Player online status; command acknowledgement and display state confirmation remain separate.

The optional noiseMeter object carries the Noise Meter plugin’s live state and its completed ten-second history buckets. It is derived numbers only — no audio, waveform, or sample is exchanged in either direction. The screen is taken from the authenticated device credential, never from the body, and a batch is bounded to 120 records. Storage is idempotent on screen plus bucket start, so a retried heartbeat cannot duplicate history.

Request Body

application/json

The Player status document. Only the optional Noise Meter section is described here; the remaining fields are the existing heartbeat contract and are additive.

object

noiseMeter

Noise Meter plugin state. Contains no audio, waveform, or sample, and levels are the relative 0-100 Tilecast scale rather than dB, dBA, or SPL.

object

status

Allowed values: active normal loud unavailable inactive

currentLevel

The live relative level when the heartbeat was built.

number

<= 100

pendingHistory

The oldest unacknowledged ten-second buckets. Bounded per heartbeat; the rest stay queued on the Player for later heartbeats rather than accelerating the cadence.

Array<object>

<= 120 items

object

startedAt

required

Start of the fixed ten-second grid slot.

string format: date-time

averageLevel

required

number

<= 100

peakLevel

required

number

<= 100

monitoredMs

required

How much of the bucket the microphone actually covered, so a partly monitored slot is not read as ten seconds of quiet.

integer

<= 10000

warningMs

required

integer

<= 10000

loudMs

required

integer

<= 10000

triggerCount

Times the Player’s state machine entered its loud state in this bucket, counted where it happened.

integer

<= 1000

Responses

200

Heartbeat accepted. data.ignoredFields names optional playback identifiers that were malformed and therefore dropped. data.noiseHistory.accepted is how many submitted Noise Meter records the server has taken responsibility for; a Player keeps its batch until it sees that count.
