Key Linius Concepts

LVS

Linius Video Services is our SaaS core platform that comprises of APIs that index, analyze, and tag each frame in a conventional video file and transforms it into fully-searchable Virtualized Video that can personalized and resequenced on-the-fly based according to search criteria, user preferences, and other business rules.

 

LVS UI is our self-service web interface that makes it easy for you to:

  • Learn and experiment with our APIs.
  • Add & edit Virtualized Video Content.
  • View your current billable API usage.
  • Manage your login credentials.
  • Manage your API keys.

Anyone may sign up for their own free account at lvs.linius.com.
Discovery

The process where the Video Virtualization Engine™ indexes MP4 video source files video binary data to create Virtualized Video Asset, which can then be scanned by Artificial Intelligence, searched, personalized, and re-assembled.
Enrichment

The process of associating frame-level content metadata (e.g. granular information about words, people, objects, sentiments, or actions contained within specific video frames or timecode ranges) a Virtualized Video Asset. 

Enrichment metadata:

  • may be ingested by scanning a Video Asset with an integrated artificial intelligence service, or by importing an XML timecode file. 
  • defines searchable segments (clips) that can be used as building blocks for re-assembled/personalized video.
Search

Using the Linius Search API and/or Search & Assembly Widget to find segments within Enriched Video Assets that specific content (e.g. keywords, faces, imagery).
Assembly

The process of using Linius Assembly APIs and/or Search & Assembly Widget to re-sequence multiple segments from one or more Virtualized Video Assets and combine them on-the-fly in a single video stream that plays back seamlessly for end users. 
De-Virtualization The process of exporting a dynamically-assembled video (which may be comprised of segments from multiple videos) as a single, newly-rendered MP4 file. 
Asset Management

The general workflow for managing a library of Virtualized Video content, including:

  • adding, updating, and/or removing Virtualized Video Assets through the Discovery process.
  • adding/editing Asset-level metadata (e.g. Asset names or tags).

You can manage your Assets using either Linius APIs or through the LVS self-service platform UI.
   
   

Terminology

The following terminology is used in our API specifications, LVS user interface, how-to guides and tutorials.

 

Categories
Term
Enrichment

AI (Artificial Intelligence) Service - An Enrichment Partner that can scan your video files to automatically associate frame-level metadata (e.g. recognized faces, keywords, brands, sentiments) with Virtualized Video Assets.
Enrichment Alias - A name attached to an AI-detected face (typically the person's real name).
General
API: Application Programming Interface. Linius offers API endpoints for: creating and managing Virtualized Video assets (Discovery and Asset Management APIs); associating videos with frame-level metadata (Enrichment API); searching video content (Search API); dynamically assembling videos (Assembly API) and re-rendering resequenced videos. 
Assembly Assembled Video - A video comprised of re-sequenced segments from one or more Virtualized Video Assets.
Discovery, Enrichment, Assembly

Asset - In Linius technology and documentation, we use the term "Asset" to describe a Virtualized Video record that is associated with:

  • a single MP4 source file (generally hosted on a publicly-accessible, non-Linius server).
  • a unique Linius Asset ID 
  • a "human-readable" Asset Name
  • optional tags for organizing your video library. 

Please note:  The term "Asset" does not refer to the video source itself. 
Enrichment Brand(s) - In Linius technology and documentation, this generally refers to AI-detected logos and company names.
Discovery Codec - A format used for compressing/decompressing video & audio data streams. Linius supports most codecs used within MP4 wrappers (see Source File requirements).
Search Confidence - A measurement used by our Search APIs to indicate search results' likely relevance to the end-user's search criteria. This measurement may be used a factor in sorting search results.
Discovery Container - In Linius technology and documentation, this refers to the MP4 wrapper used in Discoverable source files.
Discovery Discover API - Set of Linius endpoints used for creating Virtual Video assets from MP4 source assets and managing a library of video content (e.g. naming/renaming, tagging, deleting assets).
Discovery Duration - Length of a video in hours, minutes, seconds, and frames. 
Widgets Embed page -  In Linius technology and documentation, this generally refers to a page that displays a Widget (e.g. our Search & Assembly Widget) within an iFrame.
Enrichment

Enrichment Partner - A 3rd party (i.e. non-Linus) provider of video metadata. This may be an integrated AI Service or a company that can provide timecode-based XML data feeds. 
Enrichment, Search Faces - You can create searchable segments within a video that contain one or more faces that you have manually identified or that have been automatically identified by an AI service.
Assembly Frames - In the Assembly API, a Frame is a playable object that you can use as a clip within a dynamically-assembled video or a manually sequenced playlist. It is comprised of: a specific timecode range within a single Virtualized Video asset, a Frame name, Frame tags and an optional thumbnail.
Assembly Interstitial Assets: Short segments (e.g. advertising spots) that are dynamically inserted into a single "feature" asset (e.g. a television show or movie). 
Assembly

Keyframe: A frame within a video that contains all the data for a complete picture (as opposed to intermediate or "in-between" frames, which may only contain data about the elements of an image that have changed between keyframes). Typically, the first frame in a new scene or camera shot is marked by a keyframe. 

In general, the higher your video files' keyframe density, the more precisely you can define the start/end points of the segments in your Assembled videos and playlists.
