WIMAX

  • Worldwide Interoperability for Microwave Access
  • A wireless communications standard designed to provide 30 to 40 megabit per seconds enabling the delivery of ‘last mile wireless broadband’ access as an alternative to cable and DSL (normal broadband)

Geostationary orbit

  • is an orbit whose position in the sky remains the same for a stationary observer on earth. This effect is achieved with a circular orbit 35,786 kilometres (22,236 mi) above the Earth's equator and following the direction of the Earth's rotation. An object in such an orbit has an orbital period equal to the Earth's rotational period (one sidereal day), and thus appears motionless at a fixed position in the sky to ground observers.

Astra satellites

  • Astra is the brand name for a number of geostationary communication satellites, both individually and as a group, which are owned and operated by SES S.A., a global satellite operator based in Betzdorf, in eastern Luxembourg.
  • There are 16 operational Astra satellites, the majority in five orbital locations - Astra 19.2°E, Astra 28.2°E, Astra 23.5°E, Astra 5°E, Astra 31.5°E
  • Astra's principle of "co-location" (several satellites are maintained close to each other, all within a cube with a size of 150 km) increases flexibility and redundancy.
  • 2,400 digital television and radio channels via five main satellite orbital positions to households across Europe and North Africa

HDMI

  • Modern plug/socket/Cable used to connect devices (e.g. IPTV, Set-top box, blue-ray player) to the TV
  • Male to Male Cable supporting version 1.3/1.4, 1 to 2m in length is the normal type
  • Caries Video and Sound (and network in latest versions) in one cable

Android

  • Operating system created by Google. 
  • Open ‘free’ licensing. This means the device manufacturer often adds their own 'flavour' to the look and feel of the Android software. 
  • Used to support Samsung, LG, HTC etc phones and tablets
  • Some TV manufacturers are starting to use it in the newest sets
  • Runs Android Apps (Applications)

iOS

  • Operating system created by Apple
  • Closed licensing – just for Apple
  • Used to support iPhone, iPad, Apple TV, iPod
  • Runs iOS Apps (Applications)

XBMC (http://xbmc.org)

  • Stands for Xbox media center! Originally designed as a hack for the Xbox, this has now been converted to run on many devices.
  • This is software designed to play your music and videos on the TV, with a remote friendly menu system 
  • Has been expanded to allow ‘add-ons’ which can stream tv and films
  • Supports remote controls.
  • As of 2014/15, it will be rebranded Kodi

Router/Wireless Access Point

  • Within one ‘box’ there may be one or more of this functions:
  • Modem
    • Provides the connection to the internet service provider (e.g. cable, fibre)
    • Via the WAN (wide area network) port
    • Note the modem may be separate (e.g. another box if fibre or in the aerial box if WIMAX)
  • Switch
    • Provides one or more LAN (Local area network) ports. 
    • This is where you may connect an Computer, SMART TV or IPTV Box. Always better to connect using a cable than using Wi-Fi if possible
    • Each device connects to a port and the switch allows them to pass information from one to the other
  • Router
    • Each device has a unique MAC address and is given an  IP (Internet Protocol) address by the Router (if using DHCP)
    • The router essentially knows where all the devices are located. When it sees a ‘packet’ of information, it works out the most efficient path to send it
    • Wireless Access Point (AP)
    • Sends and Receives Wi-Fi signals

DNS

    • Domain Name Server
    • Takes the URL (E.g. www.google.co.uk) and converts it to an IP address (e.g. 8.8.8.8)
    • Setup in your Router/Wireless Access point, this then configures each connected device
    • Usually the DNS is provided by your Internet Service Provider (ISP)
    • The ISP’s DNS may be slow and out of date
    • It’s a good idea to update your setting to use a free DNS like Google’s
      • Primary 8.8.8.8
      • Secondary 8.8.4.4
    • You may see a dramatic improvement when Websurfing… particularly in Spain 

VPN

    • Virtual Private Network
    • Either setup on your computer/device or in the Router/Access Point
    • Subscribe to a UK VPN Provider
    • All your internet ‘traffic’ is routed through the VPN provider
    • Things to consider
      • Subscription cost
      • Only as fast as the VPN provider (i.e. your connection generally is slower via a VPN)
      • Some service providers can detect that you are using a VPN. So they won’t work (e.g. TVCatchup)
      • If you have a VPN supported  Router/Access Point back in the UK, you may be able to set up a VPN from that, which you then connect to in Spain
