<a name="open-avb" class="anchor" href="#open-avb"><span class="octicon octicon-link"></span></a>Open AVB</h1>
<p>The Open AVB project is sponsored by the AVnu Alliance.</p>
<p>The intent is to provide components for building AVB systems. The repository
contains primarily network building block components - drivers, libraries,
\example applications and daemon source code - required to build an AVB system.
It is planned to eventually include the various packet encapsulation types,
protocol discovery daemons, libraries to convert media clocks to AVB clocks
and vice versa), and drivers.</p>
<p>This repository does not include all components required to build a full
production AVB system (e.g. a turnkey solution to stream stored or live audio
or video content). Some simple example applications are provided which
illustrate the flow - but a professional AVB system requires a full media stack </p>
<ul>
<li>including audio and video inputs and outputs, media processing elements, and
various graphical user interfaces. Various companies provide such integrated
solutions.</li>
</ul>
<p>For more information about AVB, see also the AVnu Alliance webpage at
<a href="http://www.avnu.org">www.avnu.org</a>.</p>

<a name="background" class="anchor" href="#background"><span class="octicon octicon-link"></span></a>BACKGROUND</h1>
<p>Intel created the Open AVB repository to encourage collaborative source code
development for AVB technology enabling. By publishing the source code, our
intent is to encourage standardization, stability and inter-operability between
multiple vendors. This repository - created by the Intel LAN Access Division -
is open for contributions from other vendors. </p>
<h1>
<a name="licensing-and-contribution-guidelines" class="anchor" href="#licensing-and-contribution-guidelines"><span class="octicon octicon-link"></span></a>LICENSING AND CONTRIBUTION GUIDELINES</h1>
<p>To the extent possible, content is licensed under BSD licensing terms. Linux
kernel mode components are provided under a GPLv2 license. The specific license
information is included in the various directories to eliminate confusion. We
encourage you to review the ‘LICENSE’ file included in the head of the
various subdirectories for details.</p>
<p>Third party submissions are welcomed. Our intent for third party content
contributions is to enable derivative products with minimal licensing
entanglements. Practically speaking, this means we would enforce (a) an
original-source attestation for any contributed content, and (b) rejecting
patches with GPL content into existing “BSD” licensed components. Third
party copyrights can be included provided they do not narrow the licensing
terms of an existing component.</p>
<p>Prior to accepting a commit, Intel may perform scans using third-party tools
to identify suspected hits of GPL code. Intel may also perform vulnerability
scans of patches in an attempt to find various coding errors such as memory
leaks, buffer overflows and usage of uninitialized variables. The submitter
will be asked to correct any detected issues prior to a commit. Owners
of submitted third-party content are free to apply changes without supervision
by Intel.</p>

<p>Jeff Koftinoff maintains a repository of AVDECC example open
source code. AVDECC is a management layer, similar to SNMP MIB formats,
which enables remote devices to detect, enumerate and configure AVB-related
devices based on their standardized management properties.</p>
