When a program is played back the recorded subtitles are displayed along with the program. The from scratch in the title means that all the software used to build this system is royalty free and has been built from source code.% \end{comment} \vspace{1cm} \begin{center}\includegraphics[width=8cm]{images/case-front}\par\end{center} \label{fig:Case} %begin{latexonly} \lhead{Contents} \newpage \tableofcontents{} \newpage \lhead{Section \thesection} %end{latexonly} \section{Introduction} \index{PVR}PVR from scratch is a project to build a \index{Personal Video Recorder}Personal Video Recorder (PVR) using open source software and easily obtainable hardware. The hardware is build from personal computer components, the operating system is Linux and the PVR software is Python programs. Python in a scripting language that runs on various platforms including Microsoft Window, Mac OsX and Linux. \section{Installation} There are a few things that need to be done during the installation of the system. As the system is delivered it uses analogue audio. The following sections describe what may need to be changed for you. \subsection{\index{Introduction!Audio Connections}\index{Audio}Audio Connections} The audio can be sent either digitally or as analogue. If the system is being connected to a television through a \index{SCART}SCART connector then analogue is used. If the system is connected to a AV receiver\-/decoder then one of the two digital connections can be used. The optical digital connector located at the top right corner of the rear panel or the coax digital output at the bottom of the rear panel. See Figure \vref{fig:Rear-Panel-Connections} for the locations of these connectors. To configure the system to use digital output the file \index{asound.conf}/etc\-/asound.conf needs to have the following lines changed to: \begin{minipage}[t]{1\textwidth}% \begin{lyxcode} {\footnotesize pcm.!default~\{}~\\ ~{\footnotesize ~~~type~plug}~\\ ~{\footnotesize ~~~\#~Uncomment~digital-hw~for~digital~output~and~comment~analog-hw.}~\\ ~{\footnotesize ~~~\#~`\#'~is~the~comment~symbol.}~\\ ~{\footnotesize ~~~\#slave.pcm~analog-hw~~~~~~\#~analog~by~default}~\\ ~{\footnotesize ~~~slave.pcm~digital-hw~~~~~\#~digital~by~default}~\\ ~{\footnotesize ~~~\#~These~downmix~the~audio~to~48kbps}~\\ ~{\footnotesize ~~~\#slave.pcm~dmix-analog~~~~\#~analog~downmix~by~default}~\\ ~{\footnotesize ~~~\#slave.pcm~dmix-digital~~~\#~digital~downmix~by~default}~\\ {\footnotesize \}}{\footnotesize \par} \end{lyxcode} \end{minipage}% This is a little bit confusing but the configuration only needs to be done once. \begin{center}% \begin{figure}[H] \includegraphics[width=16cm]{images/rear-side.pstex} \caption{\label{fig:Rear-Panel-Connections}Rear Panel Connections} \end{figure} \par\end{center} \subsection{Network Connections} An Internet connection is required for automatic updating of the TV schedule and program updates. The Internet connection can be through either a CAT6 network cable or through a wireless LAN. When the machine is powered on it will use try the Ethernet cable connection first and then the wireless LAN. The wireless LAN can been configured for WEP 64 security encryption. See Figure \vref{fig:Rear-Panel-Connections} for the locations of these connectors. The wireless LAN needs to have the ESSID configured and the WEP KEY changed to match your wireless LAN router or access point. These setting can be changed by editing the /etc\-/sysconfig\-/wireless file. Both the Ethernet and the wireless LAN connections use the DHCP service, so they automatically receive an IP address and other network information. \subsection{System Machine Name} The system name has been set to {}``freevo'' this is used when connecting to the machine from another PC. It can be changed by editing the /etc\-/sysconfig\-/network file and changing freevo to another name. \subsection{Date and Time Service} The system time is automatically updated from the Internet. The file /etc\-/ntp.conf is automatically configured from the DHCP server that provides the IP address. \subsection{Web Browser Password} Freevo also has a Web server that allows programs to be scheduled for recording from another PC. The user name and password to the web browser are freevo and freevo respectively. These can be changed in the file /etc\-/freevo\-/local\_conf.py. There are many other preferences that can be changed in the local\_conf.py file but these need to be changed very carefully otherwise freevo may not run correctly. (The current update system caused these changed to be overwritten every day.) \section{Remote Controller} The remote controller, shown in Figure \vref{fig:Remote-Controller}, is used to control the system.
