3 System Overview

Topology

Description

Access Point

Both Mobile device and the Dongle are
connected to same Access Point

Direct Connection using Hotspot on the
handset

Mobile device hosts an Access Point and the
dongle is the client

Direct Connection using W i-Fi Direct

Mobile device and the dongle form a W I-Fi
Direct network

3.1 Streaming Mode

This mode uses DLNA (Digital Living Network Alliance) protocol: the Smart Phone (or any other
device on the network) provides DMC, and optionally DMS functionality while the dongle acts as
DMR. The smart phone typically does not transcode the content as long as it conforms to DLNA
codec specification. Note that DLNA discovery and connection works over any IP network. DTCP/IP
can be used for premium content.

Following network topologies can be supported by this mode.
