Sampling

The reduction of a continuous time-signal to a discrete-time signal. 

Scalable Video Coding

Abbreviated as SVC. An extension of the video compression standard H.264/MPEG-4 AVC.

SCTE-35

ANSI/SCTE 35 2013 is a joint ANSI/Society of Cable and Telecommunications Engineers standard that describes the inline insertion of cue tones in MPEG-TS streams. The full standard name is "Digital Program Insertion Cueing Message for Cable."

SCTE-67

Recommended practice for Digital Program Insertion for Cable. In particular, the SCTE-67 document makes recommendations on how to maintain proper time synchronization between servers and splicers. These recommendations include the time synchronization method used between servers and splicers; methods for configuring splicer controlled Ad Insertion Systems; and methods for monitoring the proper timing of Cue Messages.

SCTE-104

ANSI/SCTE104 2012 is a joint ANSI/Society of Cable and Telecommunications Engineers standard that defines the Communications API between an Automation System and the associated Compression System that will insert SCTE 35 private sections into the outgoing Transport Stream.

Secure Reliable Transport

Abbreviated as SRT. A video streaming technology that brings the best quality live video over the worst networks. It accounts for packet loss, jitter, and fluctuating bandwidth, maintaining the integrity and quality of your video. With SRT, you can keep your streams secure and easily traverse firewalls. SRT is included with all Haivision streaming solutions.

Secure Shell

Secure Shell (SSH). A cryptographic network protocol for operating network services securely over an unsecured network.

Secure Sockets Layer

Secure Sockets Layer (SSL). Like its successor, Transport Layer Security (TLS), a cryptographic protocol that provides communications security over a computer network.

Security Target

Security Target (ST). An ST defines information assurance security and functional requirements for the given information system product, which is called the Target of Evaluation (TOE). An ST is a complete and rigorous description of a security problem in terms of TOE description, threats, assumptions, security objectives, security functional requirements (SFRs), security assurance requirements (SARs), and rationales. The SARs are typically given as a number 1 through 7 called Evaluation Assurance Level (EAL), indicating the depth and rigor of the security evaluation, usually in the form of supporting documentation and testing, that the product meets the SFRs.

Server Message Block

Server Message Block, also known as Common Internet File System (CIFS), operates as an application-layer network protocol mainly used for providing shared access to files, printers, and serial ports and miscellaneous communications between nodes on a network.

Server Set Identifier

Abbreviated as SSID. The primary name associated with an 802.11 wireless local area network (WLAN).

Service Principal

An application within Azure Active Directory, which is authorized to access resources or resource group in Azure. 

Simple Object Access Protocol

Abbreviated as SOAP. A protocol specification for exchanging structured information in the implementation of web services in computer networks.

SMB

Server Message Block, also known as Common Internet File System (CIFS), operates as an application-layer network protocol mainly used for providing shared access to files, printers, and serial ports and miscellaneous communications between nodes on a network.

SMTP

Simple Mail Transfer Protocol. Standard protocol for email transmission.

SOAP

Abbreviation for Simple Object Access Protocol. A protocol specification for exchanging structured information in the implementation of web services in computer networks.

SRT

Abbreviation of Secure Reliable Transport. A video streaming technology that brings the best quality live video over the worst networks. It accounts for packet loss, jitter, and fluctuating bandwidth, maintaining the integrity and quality of your video. With SRT, you can keep your streams secure and easily traverse firewalls. SRT is included with all Haivision streaming solutions.

SRT extension

SubRip text files. File format used to store subtitles. Side car files that contains closed captioning data for a video file with a corresponding file name.

SSH

Secure Shell (SSH). A cryptographic network protocol for operating network services securely over an unsecured network.

SSID

Abbreviation of service set identifier. The primary name associated with an 802.11 wireless local area network (WLAN).

SSL

Secure Sockets Layer (SSL). Like its successor, Transport Layer Security (TLS), a cryptographic protocol that provides communications security over a computer network.

Security Target (ST). An ST defines information assurance security and functional requirements for the given information system product, which is called the Target of Evaluation (TOE). An ST is a complete and rigorous description of a security problem in terms of TOE description, threats, assumptions, security objectives, security functional requirements (SFRs), security assurance requirements (SARs), and rationales. The SARs are typically given as a number 1 through 7 called Evaluation Assurance Level (EAL), indicating the depth and rigor of the security evaluation, usually in the form of supporting documentation and testing, that the product meets the SFRs.

Stream Bundling

Establishes a single network connection to send all RTMP adaptive bitrate streams to a CDN. Limelight and Ustream require the use of stream bundling, while Akamai recommends against it.

Streaming

Mulitmedia constantly received by and presented to an end-user while being delivered by a provider. 

Subnet Mask

The bitmask that when applied by a bitwise AND operation to any IP address in the network, yields the routing prefix. Subnet masks are also expressed in dot-decimal notation like an address. For example, 255.255.255.0 is the network mask for the 192.168.1.0/24 prefix.

SVC

Abbreviation of Scalable Video Coding. An extension of the video compression standard H.264/MPEG-4 AVC.
