A

Adaptive Bitrate (ABR) Streaming
A method of video streaming over the internet where the source content is encoded at multiple bitrates, then each bit rate streams are segmented into small multi-second parts.
Advanced Encryption Standard (AES)
Is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST). It is part of Stream Security.

B

Bitrate
The number of bits that are conveyed or processed per unit of time.

C

Cloud DVR
Saving of the live stream video for an identified period of time.
Cloud Transcoding
Taking the process of transcoding (converting a video file from one format to another) through a SaaS platform.
Content Delivery Network (CDN)
A system of distributed servers (network) that deliver content to a user, based on the geographic locations of the user, the origin and the content delivery server.

D

E

Encoding
The process of taking an input signal and converting it to a compressed output format. There exist Software encoder and Hardware Encoder.

F

G

Geo restriction
A form of technological protection measure where access to Internet content is restricted based upon the user's geographical location on the player or CDN level. It is part of Stream Security.

H

Hardware Encoder
Hardware encoders are dedicated processors that use a designed algorithm to encode video and data into streamable content. These encoders can come in smaller, portable boxes or larger permanent fixtures. It is part of Encoding.
HTTP Live Streaming (HLS)
Internet-based media streaming communication protocol implemented by Apple Inc as part of its QuickTime, Safari, OS X, and iOS software.

I

Ingest Point
The act of consuming video that is sent from a broadcaster in the live backend.
Ingest
The process of capturing, transferring, or importing video, audio, still images, and metadata to your computer's hard disk, which creates media files.

J

K

L

Live Streaming
The Streaming of a Live video online to many viewers at one time.
Latency
The delay between the camera capturing the event, and the event being displayed to the viewers.

M

N

O

P

Q

R

Redundancy
The process of having excess or duplicate video streams that can continue to perform in the event of malfunction of some of the parts.
Real-Time Messaging Protocol (RTMP)
RTMP protocol was designed for high-performance transmission of audio, video, and data between Adobe Flash Platform technologies.

S

Software Encoder
Software encoders are programs that run on a computing device like your laptop or desktop computer. Unlike hardware encoders, these can be easily updated when a new version or upgrade is available. Even though these can lack overall latency speed that hardware encoders can have. It is part of Encoding.
Single sign-on (SSO)
Is a session and user authentication service that permits a user to use one set of login credentials (e.g., name and password) to access multiple applications.
Stream security
Precautions to ensure external parties can’t get access to the live stream.
Slide Synchronization
Automatically record and sync slides with live stream video with no post-production required.
Static Entry Point
Allows for a long-running live job that can be activated and deactivated while keeping the entry point URLs and playback URLs static and re-usable. This feature allows customers to configure their encoder in their facilities or the field and allows the customer to create their own scheduling logic for live channels or programs.

T

Transcoding
Converts a video file from one format to another, to make videos viewable across different platforms.

U

V

Video Stream Compression
Video compression uses coding techniques to reduce redundancy in video data. Compressing a video increases processing efficiency and decreases the overall size of the video being streamed. The Industry standard is H.264 (better known as MPEG-4).
