Definition: Audience metrics including view counts, watch time, unique viewers, and geographic distribution tracked for streams and assets.Tags: video:studioTabs: solutionsContext: Livepeer Studio provides a Viewership API returning per-asset or per-stream engagement metrics; data is collected from the Livepeer Player or via the reportPlayback API endpoint in custom players.Status: currentPages: solutions/analytics, solutions/api
Definition: A media delivery model where recorded video content is stored server-side and streamed to viewers on request at any time, in contrast to live streaming.Tags: video:deliveryTabs: developers, solutionsAlso known as: VOD, on-demand videoExternal: Video on demand (Wikipedia)Status: currentPages: solutions/vod, developers/video-on-demand

Definition: Delegators overriding their orchestrator’s governance vote with their own independent stake-weighted vote on a specific proposal.Tags: web3:governance, operational:governanceTabs: community, lptContext: Livepeer’s governance design allows delegators to vote independently from the orchestrator they bonded to; if a delegator casts their own vote, it detaches their stake-weight from the orchestrator’s vote. The orchestrator’s vote applies only to stake whose delegators have not individually voted.Status: currentPages: community/governance, lpt/governance
Definition: Number of rounds (1) between governance proposal creation and the start of the voting period.Tags: operational:governanceTabs: communityContext: The voting delay in Livepeer governance gives stakeholders time to review a new proposal before voting opens, preventing snap votes on proposals the community has not had time to analyze.Status: currentPages: community/governance
Definition: Number of rounds (10) during which token holders can cast votes on a governance proposal.Tags: operational:governanceTabs: communityContext: The Livepeer voting period lasts 10 protocol rounds; votes cast via LivepeerGovernor are weighted by bonded stake, and delegators may override their orchestrator’s vote during this window.Status: currentPages: community/governance
Definition: The weight of a participant’s vote in Livepeer on-chain governance, determined by their total bonded LPT stake at the block when the proposal was created.Tags: livepeer:protocol, web3:governanceTabs: community, lptContext: Voting power in Livepeer is stake-weighted, not one-token-one-vote; delegators can override their orchestrator’s vote with their own stake-proportional vote via vote detachment.Status: currentPages: community/governance, lpt/governance
Definition: Dedicated GPU memory used for storing graphics data, model weights, and intermediate tensors during AI inference.Tags: technical:infraTabs: developers, orchestratorsExternal: Video random-access memory (Wikipedia)Status: currentPages: developers/compute, orchestrators/ai

W

Definition: An AI model that is already loaded into GPU memory and ready to serve inference requests immediately, without the cold-start latency of loading from storage.Tags: ai:concept, livepeer:configTabs: about, developers, gateways, orchestrators, resourcesContext: In Livepeer’s AI network, orchestrators can pre-load (“warm”) models in GPU VRAM to guarantee fast response times; warm models are declared in the aiModels.json config and prioritized for latency-sensitive pipelines. During the current beta, orchestrators typically support one warm model per GPU.Status: currentPages: orchestrators/ai, resources/glossary
Definition: Biweekly informal community call for development updates and ecosystem news.Tags: operational:communityTabs: communityContext: The Water Cooler is a recurring Livepeer community call with a lighter format than Treasury Talk or Dev Call; it covers ecosystem news, informal Q&A, and community social discussion.Status: currentPages: community/events, community/social
Definition: HTTP callback mechanism where a server sends an automated POST request to a configured URL when a specified platform event occurs.Tags: technical:devTabs: solutions, developers, gateways, orchestratorsExternal: Webhook (Wikipedia)Status: currentPages: solutions/webhooks, developers/events, orchestrators/discovery
Definition: Mechanism for orchestrators to dynamically advertise their AI capabilities to gateways via HTTP webhook callbacks rather than only relying on on-chain registration.Tags: livepeer:protocol, technical:devTabs: orchestratorsContext: Provides a flexible, off-chain channel for capability advertisement. Gateways can call a registered webhook endpoint to retrieve the orchestrator’s current capability set, enabling real-time updates without on-chain transactions.Status: currentPages: orchestrators/discovery, orchestrators/config
Definition: Open-source project and W3C/IETF standard providing browsers and mobile apps with peer-to-peer real-time audio, video, and data exchange over UDP without plugins.Tags: video:protocol, technical:protocolTabs: solutions, developers, resourcesExternal: WebRTC (Wikipedia)Status: currentPages: solutions/webrtc, developers/webrtc, resources/glossary

Definition: The smallest denomination of Ether, where 1 ETH equals 10^18 Wei; used in on-chain price calculations and payment ticket values.Tags: web3:tokenTabs: gateways, orchestrators, lptExternal: Ether denominations (ethereum.org)Status: currentPages: gateways/pricing, orchestrators/pricing
Definition: Configurable scoring parameters — including stake weight, price weight, and random selection weight — that the gateway uses to rank and select orchestrators during discovery.Tags: livepeer:configTabs: gatewaysContext: Weight factors (e.g., selectRandWeight, selectStakeWeight, selectPriceWeight) let gateway operators tune the trade-off between cost, decentralization, and performance in orchestrator selection. Adjusting these requires understanding their interaction with the scoring algorithm.Status: currentPages: gateways/routing, gateways/discovery

Definition: The configured likelihood that any given micropayment ticket is a winning ticket; a lower probability means larger face values per winning ticket.Tags: economic:paymentTabs: orchestratorsContext: Win probability is a parameter negotiated between gateway and orchestrator. Lower win probability reduces on-chain redemption frequency (and gas costs) at the expense of larger, less frequent payouts.Status: currentPages: orchestrators/payments, orchestrators/protocol
Definition: A probabilistic payment ticket whose random outcome meets the configured win probability threshold, entitling the orchestrator to redeem it on-chain for its ETH face value.Tags: economic:paymentTabs: about, orchestratorsContext: In Livepeer’s payment system, most tickets are non-winning; only the fraction that statistically win are submitted to the TicketBroker for on-chain redemption, keeping gas costs low while maintaining correct expected payment values.Status: currentPages: about/payments, orchestrators/payments
Definition: A Livepeer node running Docker containers for AI models or transcoding processes, executing compute tasks delegated by an orchestrator.Tags: livepeer:roleTabs: resourcesContext: Workers are the compute leaf nodes in a Livepeer orchestrator pool. An orchestrator can coordinate many workers to scale capacity horizontally; each worker connects via the orchSecret and processes jobs assigned by the orchestrator.Status: currentPages: resources/glossary, resources/protocol
Definition: Total amount of work assigned to an orchestrator — the aggregate of active sessions, concurrent segments, and AI inference requests being processed at a given time.Tags: operational:processTabs: orchestratorsContext: Workload determines whether an orchestrator is at capacity. The -maxSessions flag caps the maximum concurrent workload. Monitoring workload against capacity helps operators tune pricing and hardware scaling decisions.Status: currentPages: orchestrators/performance, orchestrators/operations
Definition: Focused execution teams organized around specific domains, translating Advisory Board recommendations into phased initiatives.Tags: livepeer:entity, operational:governance, operational:communityTabs: communityContext: Workstreams are the primary execution structure within Livepeer’s post-SPE governance model; each workstream has a defined domain, accountable lead, and milestone timeline funded through the treasury.Status: currentPages: community/governance, community/treasury
