Chapter 8. HAVi > Framework

8.2. Framework

While this chapter starts with a short review of the complete HAVi specification, the focus is only on the Level 2 GUI API, also known as HAVi L2 GUI, which was adopted by most application-layer iTV standards (as opposed to transport standards).

8.2.1. The Home Network

The home network allows a single device, or a group of devices communicating amongst themselves, to deliver a service to a user or an application. When it is necessary for a device to interact with a user, a GUI for the device may be presented on a device with display capabilities. Therefore, each device has, at a minimum, enough functionality to allow it to communicate with other devices in the system.
