ASRock Nettop and Mythbuntu Demonstration
UPDATE: I have installed Mythbuntu 12.04 on to my ASROCK. For the Australian Freeview channels the built-in tuner settings now work. You are no longer required to use a channels.conf file. The EPG also now works and you may scheudle programs recordings via the onscreen guide.
Upgrading to Mythbuntu 11.04 (Natty Narwhal) enabled my ASRock remote control out of the box. The previous version was unable to detect the remote control.
Upgrading fixed playback of the high definitions channels as selecting some would crash the previous version of MythTV. All the high definition channels (ONE HD, ABC News 24, SBS HD, 7mate and GEM) now work.
I am still trying to enable the off air Freeview EPG. Currently the heading of Unknown is displayed where programming information should appear.
This screencast shows the computer booting and details the following television packages:
- Freeview Melbourne,
- Melbourne Amateur TV repeater,
- TPG IPTV,
- GOD TV streaming,
- TBN streaming,
- ACC TV streaming.
The screencasts shows TPG IPTV being streamed using VLC. This is due to the remote control being used in the demonstration. The TPG IPTV channels are also available in MythTV (Channels 300 to 330) but require different keystrokes on the console.
I have added a few accessories to my ASRock ION 3D PC.
I purchased a USB PC Remote Control Windows Media Center XP New from ebay for $7. This allows control of the desktop using both keyboard and mouse actions.
The remote control includes a receiver eye that plugs in to a USB port of the ASRock. It is about 40cm long and this should suit most installations. The receiver has a green acknowledgement LED built in. No additional software was required.
I purchased a PC VGA to TV Converter S-video Video RCA Adapter from ebay for $24. This connects to the blue VGA port of the ASRock and provides output to an old PAL tv. It is powered via a spare USB port on the ASRock.
I use an S-Video cable to connect the converter to my video switch.
Two DVB-T Tuners
As the tuner has a large size at the usb terminal. I purchased two Short USB 2.0 A Female To A Male Extension Cable Cord from ebay for $1 each. This enables easy entry to the usb connector on the rear of the computer.
As the tuner has its signal input on the left side. I purchased two Adaptor 75 ohm TV Plug to F81 Socket Right Angle from jaycar.com.au for $5 each (CAT. NO. PA3673). This enables easy entry of the RG6 antenna coaxial cable to the tuner.
To connect the tuners to the external antenna. I use a 2-Way F-Type TV Antenna Aerial Splitter from ebay for $10.
As I have an old CRT Television I wanted a cheap way of being able to get stereo sound out of the computer. I purchased a FM Transmitter from ebay for $7. It connects to a the green speaker jack on the ASRock. No additional software was required. This allows me to listen to programs using a stereo boom box. I selected an unused FM frequency and tuned the boom box to that same frequency.
TIP: Buy a FM Transmitter with USB power. Most models on sale only supported battery and automobile.
As the FM Transmitter did not come with a USB power cable. I purcashed a 25cm Right Angle Male A to Male A USB Cable from ebay for $2. It connects to a spare USB port on the ASRock.
Freeview in Melbourne consists of the 5 main Australian television networks plus a community television station.
- Seven Network
- Nine Network Australia
- Network Ten
- Melbourne Community Television - C31
