The person who configures, maintains, and manages the operation of the infrastructure component, such as the VidyoPortal or VidyoGateway. Administrators can control system-wide parameters and policies, establish end-user and association privileges, customize user conferencing capabilities, and more. See also Super admin and Tenant admin.

Advanced Encryption Standard. AES is a symmetric block cipher chosen by the U.S. government to protect classified information. It can be implemented in both software and hardware to encrypt sensitive data. It is essential for government computer security, cybersecurity, and electronic data protection.

Automatic Gain Control. In a video call, AGC automatically controls the gain of a signal by reducing the volume if the signal is strong and raising it when the signal is weaker, thereby keeping the audio output at a near constant level.

The maximum rate of data transfer across a given path, such as a network.

Context-aware linkingCAL maintains the click-to-connect Vidyo experience from within Epic workflows, but it also gives Epic users a robust set of features and capabilities including multiparty meetings, far-end camera control, H.323/SIP dialing capability, and support for an array of healthcare peripherals.

Common Intermediate Format. A video format used in videoconferencing systems that supports both NTSC and PAL signals. CIF is part of the ITU H.261 videoconferencing standard. It specifies a data rate of 30 frames per second (fps), with each frame containing 288 lines and 352 pixels per line.

A group of VidyoGateways used for increased capacity. One VidyoGateway is designated the Controller. In addition to handling calls itself, the Controller also controls several Standby VidyoGateways.

Short for coder/decoder or, because codecs are commonly used for compression, compressor/decompressor; a codec is any technology for compressing and decompressing data. Some popular codecs for computer video include MPEG, Indeo, and Cinepak.

Data Encryption Standard. DES is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography.

Differentiated services (DiffServ) is a computer networking architecture that specifies a simple and scalable mechanism for classifying and managing network traffic and providing quality of service (QoS) on IP networks.

Far End Camera Control. FECC allows another meeting participant to take control of your camera and use the pan-tilt-zoom (PTZ) functionality of the camera. The webcam must have the PTZ features for this feature to work.

Federal Information Processing Standard. FIPS is a program overseen by NIST and the Department of Commerce that requires specific security standards for data and encryption.

A network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. A firewall establishes a barrier between a private, trusted internal network and an untrusted network, such as the public Internet.

A management tool for H.323 multimedia networks. Depending on the demands of the specific network, the gatekeeper oversees authentication, authorization, telephone directory, and PBX (private branch exchange) services, as well as call control and routing.

Users, public meeting rooms, and VidyoConnect Rooms/VidyoRooms belong to provisioning groups. There is always at least one group, called the default group. Such groups are managed by Super and Tenant admins. Groups are subsets of Tenants. You don’t have to create any groups. However, doing so allows you to allocate resources among tenants in a way that may better suit your organization’s requirements.

The protocol that covers security and encryption for H.323 and other H.245 based terminals.

The standard used in H.323 and H.320 video conferencing that enables two simultaneous media channels in a single video conference. The second channel is used for data presentation. For example, it’s possible to see a speaking person within a main video screen and see their computer screen with diagrams, documents, screenshots, and so on.

A control signaling protocol for the exchange of end-to-end messages between communicating H.323 and H.234 endpoints/terminals.

A simple and straightforward video codec that provides enhanced compression performance and a network-friendly video representation. Also known as Advanced Video Coding (AVC).

A recommendation from the ITU Telecommunication Standardization Sector that defines the protocols to provide audio-visual communication sessions on any packet network, such as LANs and the Internet. It also sets interoperability guidelines for communication between H.323-enabled networks and the H.32X-based family of conferencing standards.

The components that provide the foundation or framework of the video conferencing solution. Vidyo infrastructure components include the VidyoPortal, VidyoRouter, VidyoGateway, and VidyoReplay.

Internet Protocol address. This is a numerical label, such as 192.0.2.1, that is connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: network interface identification and location addressing.

Multipoint Control Unit. A device in videoconferencing that connects two or more audiovisual terminals together into one single videoconference call. The MCU collects information about the capabilities of the systems at each of the videoconference endpoints and sets the conference to the lowest common denominator so that everyone can participate.

An audio and video connection of a meeting room with two or more users interacting and sharing their media streams, and optionally the windows of applications running on their machines.

Meeting rooms are virtual rooms where users of the Vidyo system can gather for video conferences. There are two types of meeting rooms:

• Personal – Each user is automatically assigned their own personal room. This is the equivalent of a “personal office” in the physical world.
• Public – Common public spaces that can be created by administrators. These are the equivalent of conference rooms in the physical world.

The VidyoConnect participant (typically the room owner) who has more capabilities than the other VidyoConnect conference participants. For example, the moderator can mute the microphones or cameras of the other call participants. The moderator is labeled Moderator under their name in the VidyoConnect UI participants list. The moderator can also create or modify a moderator PIN, enabling other participants to become the moderator by entering the PIN during the call.

A Personal Identification Number (PIN) that is configured by the room owner. Call participants can enter the PIN to claim moderator privileges.

Online Certificate Status Protocol. The OCSP is an Internet protocol used to check whether a digital certificate is valid or if it has been revoked.

Users who join and participate in meetings with the VidyoConnect desktop, mobile, or WebRTC app or with VidyoConnect Room or VidyoRoom.

A video conference that takes place between just two users. No additional participants can join a point-to-point call. Also known as a direct call.

See VidyoPortal .

Pan-Tilt-Zoom. “Pan" refers to the horizontal movement of the lens, "tilt" refers to the vertical movement of the lens, and "zoom" refers to the adjustment of the focal length of the lens.

A PTZ camera is a camera that supports remote control of direction (panning and tilting) and zooming (increasing and decreasing).

Remote Authentication Dial-In User Service. RADIUS is a client/server protocol that runs in the application layer and manages user access to a network by providing centralized authentication, authorization, and accounting services.

Virtual spaces (like virtual conference rooms) where users meet for their video conferences. When a user’s account is set up, that user is automatically assigned a room. A user can have more than one room (all accessible via his or her portal).

An enhanced topology that increases network bandwidth efficiency, decreases latency, and optimizes how VidyoRouters handle traffic. Because many of our customers don’t require the advantages that Router Pools provides, the feature is turned off by default. A small organization with few locations may not need to use of the capabilities of Router Pools right away but it’s built-in, doesn’t cost extra, and it’s ready to go when you need it.

When using one of the endpoints, such as VidyoConnect for Desktop, Mobile, or WebRTC, screen sharing is the ability to send what is displayed on your screen to the other participants in the conference so they can view your local screen. You can share from any desktop, laptop, tablet, or smartphone device.

A video format with a 640 x 360 resolution and a 16 to 9 aspect ratio.

Session Initiation Protocol. This is a signaling protocol that enables the Voice Over Internet Protocol (VoIP) by defining the messages sent between endpoints and managing the actual elements of a call.

Simple Network Management Protocol. SNMP is an application-layer protocol for monitoring and managing network devices on a local area network (LAN) or wide area network (WAN). The purpose of SNMP is to provide network devices, such as routers, serversn and printers, with a common language for sharing information with a network management system (NMS).

One of a cluster of VidyoGateways that are controlled by a single Controller VidyoGateway.

The user who has administrative privileges and is responsible for general portal configuration including network settings, components configuration, maintenance (backup and upgrades), tenant configuration, and global settings. In a multi-tenant system, the Super admin has full administrative privileges above the Tenant admin and all regular Tenant admin rights. See also Tenant admin.

Also known as H.264. A video compression standard that enables a video stream to be broken into multiple resolutions, quality levels, and bit rates.

Terminal Control String. A special routing method for incoming H.320 video calls. TCS4 allows direct inward dialing (DID) to an endpoint on the IP network through the gateway when DID is not available. H.323 endpoints on the IP network register with the gatekeeper using extension numbers. When an ISDN terminal dials one of the gateway phone numbers followed by a TCS4 extension, the call is routed directly to the corresponding IP endpoint registered with that extension.

A single VidyoPortal system can be set up to host multiple organizations known as tenants. Each Vidyo system has at least one tenant, called the default tenant. If you choose not to use the system’s built-in multi-tenant capability, every user in your entire organization belongs to the default tenant.

The person who configures and maintains the user settings for their own tenant or tenants in the video conferencing system. The Tenant admin has administrative privileges and can add, delete and manage users, set up public rooms, and set up groups (which define the maximum number of participants and bandwidth for users). All tasks that can be performed by a Tenant admin can also be performed by a Super admin; however, many Super admin tasks cannot be performed by Tenant admins. See also Super admin.

A simple identifier within the system and among other tenants. If you’re hosting multiple organizations, it might be the organization’s common name (Acme Corp., Jones Foundation, and so on). If you’ve divided your own organization into different tenants the name might reflect the tenant’s role in your organization (Board Members, Sales, New York Office, and so on).

The software client that enables users to view other users in point-to-point calls and video conferences. It’s easy to use and manage via the VidyoPortal, and it can send and receive in HD. All users are assigned a password-protected personal space, thus making it possible for meetings to be held anytime–whether impromptu or by prior arrangement. It supports standard USB webcams and runs on Macs, PCs, and mobile phones, providing an unparalleled personalized multipoint collaborative experience.

VidyoRoom SE is an installable software group video system that delivers industry-leading Ultra HD experiences on off-the-shelf computing hardware.

The VidyoGateway allows the Vidyo conferencing infrastructure to connect to traditional H.323 and SIP devices. It supports standards, such as H.239 for data collaboration, that are required for those devices to communicate, regardless of whether they are endpoints, MCUs, gatekeepers, or gateways. For example, the VidyoGateway can be integrated with SIP PBX. It seamlessly integrates into the network providing the end user with an easy experience regardless of whether they’re calling a Vidyo device or traditional H.323/SIP device.

The Epic Context-Aware Linking (CAL) integration with Vidyo that enables healthcare providers to access VidyoConnect meetings from within their Epic EHR (Electronic Health Record) system.

A performance monitoring system and analytics tool for on-premises and private cloud customers to verify and track VidyoPlatform infrastructure components (VidyoPortal and VidyoRouter), applications, and events.

VidyoPlatform works across multiple platforms by providing developers with all the necessary infrastructure and support to quickly embed high-quality, reliable, and scalable multiparty video collaboration into any WebRTC, mobile or native application, with just a few lines of code.

The VidyoPlatform includes the VidyoClient SDK, which provides the APIs for integrating such communication capabilities into a variety of applications and workflows. It also includes the VidyoPlatform Server API for call control and moderation.

The VidyoPortal provides central management of the Vidyo devices on the network. It’s an easy-to-use secure web portal that allows for integration with secure LDAP and Active Directory databases for user authentication, as well as maintaining its own user database. The VidyoPortal allows administrators from any location on the network to control every aspect of the Vidyo conferencing solution from a central location. Administrators can control system-wide parameters and policies, establish end-user and association privileges, and customize user conferencing capabilities.

The VidyoPortal also acts as a web front for all users of the system. Its flexible user interface facilitates everything required to initiate and manage a call. Users have control over adding, disconnecting, and muting/un-muting participants along with many other conference control parameters. The interface allows users to manage and customize their own contact lists and to initiate reservation-less multipoint conferences, as well as point-to-point calls.

This option requires two VidyoPortal servers to be deployed in the same subnet. One of the VidyoPortals acts as the Active VidyoPortal and the other as the Standby VidyoPortal. If the Active VidyoPortal is not reachable, the Standby VidyoPortal automatically takes over within one minute. Upon taking over, the Standby VidyoPortal uses the information it received in the last synchronization with the Active VidyoPortal.

A software component built into the VidyoRouter that enables authorized endpoints to connect while denying unauthorized connections. It also enables NAT and firewall traversal.

An optional rack-mountable appliance that enables users to stream live or prerecorded video. For instance, a webinar can be broadcast live to participants and also saved to be played back on demand by those who missed the original conference or want to view it again.
