Switched video is the process that can dynamically setup (on demand) video signal connections between two or more points. SVS services can range from the setup of data connections that allow video transfer to the organization and management of video content and the delivery of video programs.

Broadband Connection - A broadband connection is a communication link from a sender to a receiver that can transport data at 1 Mbps or faster. The broadband connection usually allows for multiple channels (logical channels) to share the same communication connection.

IP Video Adapter - A video adapter is a card, component or adapter that can convert data into a graphics format that can be displayed to a user. IPTV systems commonly use IP set top boxes (IP STBs) to adapt IP media (audio and video) channels into a format that can be used by viewing devices (such as televisions).

Media Servers - A media server is a computing device that can process requests for and deliver digital media. Media servers may access stored content or they may be gateways that adapt incoming media such as live media streams (live TV programs).

This figure shows how a basic IPTV system can be used to allow a viewer to have access to many different media sources. This diagram shows how a standard television is connected to a set top box (STB) that converts IP video into standard television signals. The STB is the gateway to an IP video switching system. This example shows that the switched video service (SVS) system allows the user to connect to various types of television media sources including broadcast network channels, subscription services, and movies on demand. When the user desires to access these media sources, the control commands (usually entered by the user with a television remote control) are sent to the SVS and the SVS determines which media source the user desires to connect to. This diagram shows that the user only needs one video channel to the SVS to have access to a virtually unlimited number of video sources.
