nDVR is the process that provides the ability to record a live stream while simultaneously allowing users to play, pause, resume, and rewind the recorded stream. You can configure settings and properties to control the archive strategy and availability of the recorded streams.

An access token contains the security credentials for a login session and identifies the user, the user’s groups, the user’s privileges, and, in some cases, a particular application. Typically one may be asked to enter the access token (e.g. string 16 random characters consists of 0-9 and a-f) rather than the usual password. Token always has an expiry date/time.

Geo-block or geoblocking is a technology that restricts access to Internet content based upon the user’s geographical location.

A domain lock is a security setting that prevents unauthorized attempts to access your CDN content by certain websites/domains.

Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol (HTTP) with the Secure Socket Layer (SSL)/Transport Layer Security (TLS) protocol.

The origin server is the first server in CDN. The clients are pushing content to the origin server. The selection of the origin server is based on the geographical location. In simply the origin is the server where the content resides.

A video codec is a software or hardware that compresses and decompresses digital video. In the context of video compression, codec is a combination of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder.

A content delivery network (or CDN), is a large distributed system of servers deployed in multiple data centers across the globe. So if an end-user puts in a request for live content from the US, a CDN will deliver it from the closest server to minimize bandwidth requirements and provide the smoothest video stream possible.
