Abstract

• A lot of new homes today are wired for network
  capabilities. With these capabilities there is
  the possibility to run audio and video anywhere
  in the house using a central server.
• The smart home should be improved from only being
  hooked up through an expensive hard wired system
  to a plug and play system that can be used in
  conjunction with an existing CAT5 network.

Background

• Current home entertainment systems consist of
  many modules
• Amp
• DVD/VCR
• Surround Sound
• Cable Box
• Receiver
• CD Player

4
Background

• There 4 Main problems with these units
• They are normally big
• They are normally kept in a cabinet
• Hard to operate
• There are a lot of wires
• Messy
• Hard to set up
• Expensive
• Not all units are compatible
• RF Modulators
• Adapters
• They only work in that specific room

5
Design Goals

• Make a Video and an Audio box to replace most of
  the units in a home entertainment system
• Make the Audio and Video units user friendly
• The Audio and Video units should be affordable to
  most people
• The units should be able to be plug in anywhere
  in the house where there are CAT5 plugs

14
Video Box

• The video box will have the following
  capabilities.
• Ethernet capabilities.
• Streaming Audio.
• Streaming Video.
• DVD/CD player.

15
Video Box

• Way of operation
• The box will be designed to interface with a TV
  and stereo system.
• It will use Text Overlay, IR remote control as
  well as a few push buttons on the device for user
  interface.
• A small LCD screen will be placed on the device
  for operation without the use of the TV, when the
  user just wants to listen to music.

16
Video Box

• Streaming video/audio.
• The box will request MPEG/WMA/DivX format files
  from the server.
• Once received the box will decode them and send
  them to be displayed on the TV screen.
• Audio files will be sent directly to the stereo
  system.
• DVD/CD player
• DVD-ROM will be built into the device so that the
  user can play CDs or DVDs right from the unit.

17
Video Box

• In order to accomplish all of the above tasks we
  decided to build a mini computer.
• We will be using VIAs Mini ITX motherboard with
  a C3 1GHz process.
• To that we will attach a DVD-ROM.
• A small LCD, IR controller, and a couple push
  buttons will be implemented into the device as
  well, for user interface.

18
Video Box

• VIAs C3 processor and the ITX motherboard are
  known for their low power operation.
• That allows us to run the device without any
  fans, which reduces the operational noise
  dramatically.
• Motherboard comes with both S-Video and
  composite video ports, which will allow easier
  interface with the TV.
