1 Video Streaming and Device Control Over Ethernet Standard version (includes errata up to March 13, 2013) 900 Victors Way, Suite 140 Ann Arbor, Michigan 48108 USA GigE Vision Specification version April 16, 2013 Page 2 of 427 GigE Vision Licensing and Logo Usage GigE Vision is a widely adopted standard and is used on hundreds of products on the market today. The standard was designed so that users of the technology can quickly and easily identify GigE Vision compliant products that will interoperate and plug and play with each other. All commercial products developed using the GigE Vision standard must license the standard and qualify for the right to use the name and logo.

2 To qualify, each product must have the proper paperwork submitted to the AIA and must pass GigE Vision compliance testing. More information on licensing GigE Vision can be found at The GigE Vision logo may be used only in conjunction with licensed products which have passed GigE Vision compliance testing. Special Note This version of the GigE Vision standard text includes all errata that have been identified in the main text since the release of the specification. These errata are highlighted using a light green background color. A comprehensive list of the changes can be found in the Document History section at the end of the document. No part of this publication may be reproduced in any form, in an electronic retrieval system or otherwise, without the prior written permission of the AIA.
