<h1>Ogg logical and physical bitstream overview</h1>

<h2>Ogg bitstreams</h2>

<p>Ogg codecs use octet vectors of raw, compressed data
(<em>packets</em>). These compressed packets do not have any
high-level structure or boundary information; strung together, they
appear to be streams of random bytes with no landmarks.</p>

<p>Raw packets may be used directly by transport mechanisms that provide
their own framing and packet-separation mechanisms (such as UDP
datagrams). For stream based storage (such as file
