<h1>Ogg logical bitstream framing</h1>

<h2>Ogg bitstreams</h2>

<p>The Ogg transport bitstream is designed to provide framing, error
protection and seeking structure for higher-level codec streams that
consist of raw, unencapsulated data packets, such as the Vorbis audio
codec or Theora video codec.</p>

<h2>Application example: Vorbis</h2>

<p>Vorbis encodes short-time blocks of PCM data into raw packets of
bit-packed data. These raw packets may be used directly by transport
mechanisms that provide
