​
A

A self-hosted addon that sits between Stremio (or WuPlay) and your debrid service. When you open a title, AIOStreams queries multiple scrapers simultaneously, filters and ranks every result, deduplicates, and returns a clean sorted stream list. One addon replaces a dozen separate torrent/debrid addons.
A modern video codec — more efficient than HEVC at the same quality, but hardware decoder support is patchy. Samsung Tizen TVs (2018–2022) and Apple TV (A15) lack a hardware AV1 decoder — these device templates hard-exclude AV1 to prevent silent playback failures.
Object-based surround audio format. Comes in two forms: TrueHD Atmos (lossless, BluRay) and DD+ Atmos (lossy, streaming). All 4K templates prefer Atmos where available.

​
B

Data throughput of a video stream, typically measured in Mbps. Higher bitrate = more data = better quality (up to a point). Core Builds uses bitrate as a primary ranking signal via the IQR Tukey fence — streams with suspiciously low or high bitrates relative to peers are deprioritised.
A lossless copy of a Blu-ray disc with no re-encoding — the video and audio bitstreams are extracted directly. Largest file sizes, highest quality. Preferred on 4K templates. Excluded on the Stream template (WEB-DL only).

​
C

A file that has already been downloaded to a debrid service’s servers. Clicking a cached stream starts playing instantly — no torrent download wait. Core Builds ISEs boost cached streams above uncached results.
The full set of Stream Expressions deployed in all active Core Builds templates: 24 ESEs (hard kills + quality gates), 3 ISEs (library / cached / language boosts), and the IQR Tukey fence PSEs. See Expression Layer.

​
D

An AIOStreams feature that stops querying scrapers early once an exit condition is met. Core Builds uses two exit conditions on 4K Apex: count(cached(resolution(totalStreams,'2160p'))) >= 5 (enough cached 4K streams found) or totalTimeTaken > 5000 (5-second hard cap). Prevents slow scrapers from causing player-level timeouts on Nuvio and similar clients.
A subscription service (TorBox, AllDebrid, Real-Debrid) that downloads torrents or NZBs to its own servers and gives you direct HTTP links. You stream from their servers rather than from the torrent swarm — faster, more reliable, ISP-friendly.
HDR format with per-frame dynamic metadata. Produces the best HDR image on compatible displays. Comes in several profiles — Profile 5 (DV-only, no HDR10 fallback) and Profile 7/8 (dual-layer, includes HDR10 fallback). Samsung Tizen TVs cannot decode DV — Samsung templates hard-exclude it.
Lossless (DTS-HD MA) and object-based (DTS:X) audio formats found on BluRay discs. High quality but large files. Excluded on Samsung templates (Tizen cannot pass these through).

​
E

A filter that removes streams from results entirely. ESEs run before PSEs — anything matched by an ESE is gone before ranking starts. Examples: CAM kill, YouTube rip kill, 3D kill, low-resolution kill. Standard templates run 24 ESEs; Lite templates run 12 (hard kills only).
A Usenet provider with a web-based search interface. Supported in AIOStreams as a scraper addon. Used in Speed 4K+ and Speed EasyNews templates — no TorBox required for the standalone EasyNews template.

​
F

An ESE that caps how many results any single scraper can contribute to the stream list. Without it, one noisy scraper can return 20 low-quality results and push better cached streams off the bottom. Current caps: Meteor ≤ 5, Comet RD ≤ 5, MediaFusion ≤ 4, EZTV ≤ 3, HdHub ≤ 3, Knaben/Torrent Galaxy/TorrentsDB ≤ 1. Library and SeaDex results are excluded from the cap.
Controls the text displayed for each stream in Stremio — the title line, metadata rows, codec, HDR tag, audio, file size, seeders, etc. Core Builds ships 14 official formatters plus 2 community formatters. All templates default to Core Nexus Elite; others can be swapped via the Formatter tab. See Formatters.

​
H

Open HDR formats. HDR10 is static metadata (most common). HDR10+ adds per-scene dynamic metadata (Samsung displays, some Samsung TVs support this). HLG is broadcast-friendly HDR. All are supported on a wider range of devices than Dolby Vision.
Current mainstream video codec. More efficient than AVC at the same quality — smaller files, same picture. Broadly supported with hardware decoders on modern devices. Preferred on most Core Builds templates.

​
I

A statistical measure of spread: the range between the 25th percentile (Q1) and 75th percentile (Q3) of a dataset. Used in Core Builds PSEs to define a “normal” bitrate window for a given title — streams inside the Tukey fence are ranked, outliers are deprioritised.
A filter that boosts certain streams to the top of results, ahead of PSE ranking. Core Builds ISEs boost: library streams, cached streams, and English-language streams. ISEs run after ESEs but before PSEs in the evaluation order.

​
N

A Usenet indexer API protocol. NZBGeek is a Newznab indexer — it returns NZB files (Usenet download links). Used in Hybrid templates (4K Hybrid, Hybrid, Hybrid Lite) as a second source alongside TorBox.
A popular Usenet indexer that supports the Newznab API. Required for Hybrid templates. Provides NZBs (Usenet releases) as a supplement to TorBox’s torrent cache.
A file that describes a Usenet post (like a torrent file for Usenet). AIOStreams can query Newznab indexers and return NZBs to TorBox or another debrid service for downloading.

​
P

pow(0.95, daysSinceRelease) — a mathematical function used in Core Builds PSEs to produce a smooth bitrate window that narrows over time. A new release (day 0) gets ±40% tolerance; by day 30 it’s ±9%; by day 60 it’s ±2%. Replaces the old hard 60-day cliff.
A filter that scores and ranks streams into quality tiers. PSEs don’t exclude — they sort. Core Builds uses IQR Tukey fence PSEs for statistically sound bitrate-based ranking. The highest-scoring PSE match determines a stream’s position in the final sorted list.

​
R

The team that produced a release (e.g. FraMeSToR, FLUX, BHDStudio). Some groups are consistently high quality; others are known for bad encodes. Core Builds embeds 37 inline rankedRegexPatterns per template (score range −200 to +100), supplemented by Vidhin05’s 174-pattern set via syncedRankedRegexUrls. Elite groups surface above generic encodes automatically.
See BluRay REMUX.
A re-released version of a file correcting a quality defect in the original (audio sync issue, corrupt encode, wrong runtime). REPACK is from the original group; PROPER is from another group flagging the issue. Core Builds passthrough ISEs are planned to always surface these ahead of quality gates.

​
S

An AIOStreams addon that searches for streams — Comet, MediaFusion, TorBox Search, Knaben, Meteor, etc. Each scraper queries different sources (torrent indexes, debrid caches, Usenet). Core Builds templates configure which scrapers are enabled and their timeouts.
An anime-only best-release database. Tracks which fansub/encode group produced the definitive release for each anime title. Used in Anime templates — seadexBestOnly restricts results to SeaDex-approved releases when data exists.
The expression language built into AIOStreams for writing PSEs, ESEs, and ISEs. Supports statistical functions (iqr, q1, q3, percentile), stream filters (bitrate, resolution, quality, cached), math (pow, sqrt), and array operations (merge, count, slice, pin).

​
T

A JSON configuration file that defines every aspect of an AIOStreams setup — addons, filters, sorting, formatter, deduplication, and branding. Core Builds provides 45+ templates for different services, resolutions, and devices.
A Torrentio fork that indexes 21+ torrent providers: YTS, 1337x, Nyaa, AnimeTosho, Rutor, Rutracker, Torrent9, and regional trackers. Works natively with TorBox — no API key required. Used in Core Builds as a backup scraper (flood guard ≤ 1) added in v2.9.5.
A debrid service with both torrent and Usenet support. Core Builds is primarily built for TorBox subscribers. Plans: Essential (basic cached-only) and Pro (full Usenet + uncached support).
Dolby’s lossless audio format, found on BluRay discs. Often paired with Atmos metadata. Requires passthrough to an AVR — Samsung TVs and most streaming devices cannot decode TrueHD natively. Excluded on Samsung templates.
A statistical outlier detection method: [Q1 - 1.5×IQR, Q3 + 1.5×IQR]. Streams with bitrates inside the fence are “normal” for that title; streams outside are outliers (unusually low-quality or suspiciously large). Core Builds uses this to rank within-window streams highest.

​
U

A torrent or NZB not yet downloaded to a debrid service’s servers. AIOStreams can return uncached results — clicking them triggers a download first (may take minutes to hours). Core Builds ISEs sort cached results above uncached by default.
A distributed text and binary posting system predating the web. Used as a file distribution network — NZBs point to binary posts containing video files. Faster propagation than torrents for new releases; no seeder dependency. Supported via Newznab indexers (NZBGeek) in Core Builds Hybrid templates.

​
W

A stream captured directly from a digital distribution source (Netflix, Amazon, Disney+) at its native bitrate — no re-encoding. Clean, consistent quality. The default quality tier on Stream and Essential templates.
A recording of a WEB-DL stream, often re-encoded at lower bitrates. Lower quality than WEB-DL. Ranked below WEB-DL in Core Builds sort criteria.
A web-based streaming client that works alongside AIOStreams. Useful for Chromecast, smart TVs, or any device without a native Stremio app.
