[Tex/LaTex] Removing page number from title frame without changing the theme

beamer

I am using theme Madrid and would like to keep my title page and the rest of my presentation as it is and ONLY make the following changes:
1- Don't count title frame towards the total number of frames

2- Do not enter frame number and total number of frames in the title frame.

For number 1, I can manually change total number of frames available and I was wondering if there is a more automatic way to do it.

\documentclass {beamer}
\mode<beamer>{\usetheme{Madrid}}
\title[Test Title]{Test}

\begin{document}
\begin{frame}
\titlepage
\end{frame}
\begin{frame}
\frametitle{First test frame}

\begin{itemize}
\item Item 1
\item item 2
\end{itemize}
\end{frame}

\begin{frame}
\frametitle<beamer>{Second frame}
\begin{block}<beamer>{Example block}
Some text in the block
\end{block}
\end{frame}

\end{document}

This code has three frames; first one title and the next two are my actual presentation. Currently the page numbers in the slides are 1/3, 2/3, and 3/3. What I am ideally looking for is: keeping the presentation as it is and changing the page numbers to "nothing in the title fram" and 1/2 in the second frame and 2/2 in the third frame. I hope it is clear.

bloodworks gives the simplest solution. However, if you want to retain exactly the formatting for the title page, but just not have the page number information, then you can redefine the footline template just for that frame as follows:

\documentclass {beamer}

\mode<beamer>{\usetheme{Madrid}}
\title[Test Title]{Test}

\begin{document}
\bgroup
\makeatletter
\setbeamertemplate{footline}
{
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
    \usebeamerfont{author in head/foot}\insertshortauthor\expandafter\beamer@ifempty\expandafter{\beamer@shortinstitute}{}{~~(\insertshortinstitute)}
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
    \usebeamerfont{title in head/foot}\insertshorttitle
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
    \usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
%    \insertframenumber{} / \inserttotalframenumber\hspace*{2ex} 
    \hspace*{6ex}
  \end{beamercolorbox}}%
  \vskip0pt%
}
\makeatother
\begin{frame}
\titlepage
\end{frame}
\egroup

\setcounter{framenumber}{0}

\begin{frame}
\frametitle{First test frame}

\begin{itemize}
\item Item 1
\item item 2
\end{itemize}
\end{frame}

\begin{frame} More \end{frame}

\end{document}

Sample output

The code makes a local group around the first frame via \bgroup / \endgroup and then contains a copy of the footline template from beamerouterthemeinfolines.sty with the insertion of "frame numuber / total framenumber" commented out and replaced by an appropriate amount of horisontal space.

Had not been for the " / " between these numbers you could just have set the commands \insertframenumber and \inserttotalframenumber to insert a single space each in this group.

After discussion with bloodworks, one may prefer to package the above up in to a macro \mytitleframe as below. Such a definition could then be moved to a private style file.

\documentclass{beamer}

\mode<beamer>{\usetheme{Madrid}}

\makeatletter
\def\mytitleframe{\bgroup
\setbeamertemplate{footline}
{
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
    \usebeamerfont{author in head/foot}\insertshortauthor\expandafter\beamer@ifempty\expandafter{\beamer@shortinstitute}{}{~~(\insertshortinstitute)}
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
    \usebeamerfont{title in head/foot}\insertshorttitle
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
    \usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
%    \insertframenumber{} / \inserttotalframenumber\hspace*{2ex} 
    \hspace*{6ex}
  \end{beamercolorbox}}%
  \vskip0pt%
}
\maketitle
\egroup
\addtocounter{framenumber}{-1}
}
\makeatother

\title[Test Title]{Test}

\begin{document}

\mytitleframe

\begin{frame}
  \frametitle{First test frame}

  \begin{itemize}
  \item Item 1
  \item item 2
  \end{itemize}
\end{frame}

\begin{frame} More \end{frame}
