<p>
The main goal of this profile is to simplify and harmonize the production and delivery of <a>TV Services</a> to web enabled devices. For the purposes of this document a <dfn id="dfn-tv-service">TV service</dfn> is a commercial video service that may include elements of interactivity and that provides a coherent user experience. TV services are usually divided into two main groups: <dfn title="scheduled service" id="dfn-scheduled-service">scheduled</dfn> or <dfn title="linear service" id="dfn-linear-service">linear</dfn> services are the ones that have to be consumed by the user at the particular point in time when they are offered (e.g. a broadcast TV channel); <dfn title="on-demand service" id="dfn-on-demand-service">on-demand</dfn> services are the ones that can be consumed by the user at any point in time (e.g. web video portals).
</p><p>
In order to consume them, users need a <dfn id="dfn-device">device</dfn> that is able to present TV services. Traditionally TV services have been consumed mainly via <a href="#dfn-tv-set" class="internalDFN">TV set</a>s or <a href="#dfn-stb" class="internalDFN">STB</a>s connected to a display. Nowadays users have a wide range of devices (e.g. PC, laptops,smartphones, tablets) available both in their home and outside and expect to be able to access to TV services from any device.
</p><p>
- <a href="#dfn-tv-service" class="internalDFN">TV service</a>s can be delivered to users via a variety of means. The most common means is via a uni-directional TV <dfn id="dfn-broadcast-network">broadcast network</dfn>. Different standards have been defined for such purpose, such as <a href="#dfn-dvb" class="internalDFN">DVB</a>, <a href="#dfn-atsc" class="internalDFN">ATSC</a>, <a href="#dfn-isdb" class="internalDFN">ISDB</a>. <a href="#dfn-tv-service" class="internalDFN">TV service</a>s may also be delivered via bi-directional IP connections, mainly via the Internet. An emerging scenario is represented by content streamed directly between devices connected via the <dfn id="dfn-home-network">home network</dfn>. The term <a href="#dfn-home-network" class="internalDFN">home network</a> refers to the networking infrastructure that facilitates communications between devices within the home. This may range from a single legacy IPv4 subnet to multiple IPv4 subnets and dual stack or IPv6 environments and will typically (but not always) be connected to the Internet.
