TV 2.0 Architecture
The following diagram shows the generic implementation
use case for TV 2.0.
Figure 2: TV 2.0 Architecture
In this architecture, the PC video and audio is presented
to the user’s TV without disturbing any of the existing
A/V sources (e.g. cable-TV source, DVD, etc.) connected to
the TV. The user can control their existing A/V devices through
a standard remote control as well as fully control a remote
PC through any common USB interface device (mouse, keyboard,
etc.). The PC Box and TV Box units provide the means for extending
PC video (i.e. VGA or DVI), audio (USB) and control (USB)
interfaces to the TV over any type of transmission media,
including Cat 5, Coax, and WiFi, Powerline, and Fibre. The
TV can be located anywhere in the home and the TV box sits
next to it. The TV Box has multiple USB connections for inputs
such as USB Flash drives for uploading pictures and USB dongles
for supporting wireless USB devices such as Bluetooth keyboards
and mice. The TV Box can also be integrated into a cable Set
Top Box or even the TV itself.
As shown in figure 2, the three main issues for deploying
TV 2.0 are:
1). Video Signal Options
2). Signal Transmission Media
3). Peripheral Connectivity
1 - Video Signal Options
The video signal originating from the PC can be reproduced
in a number of formats:
