Live Video Glossary
- 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.
- The number of bits that are conveyed or processed per unit of time.
- 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.
- The process of taking an input signal and converting it to a compressed output format. There exist Software encoder and Hardware Encoder.
- 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.
- 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.
- Ingest Point
- The act of consuming video that is sent from a broadcaster in the live backend.
- The process of capturing, transferring, or importing video, audio, still images, and metadata to your computer's hard disk, which creates media files.
- Live Streaming
- The Streaming of a Live video online to many viewers at one time.
- The delay between the camera capturing the event, and the event being displayed to the viewers.
- 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.
- 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.
- Converts a video file from one format to another, to make videos viewable across different platforms.
- 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).
