IEEE1394 General

I have heard that a license agreement is required in order to use the IEEE1394.
Where should I go for this license agreement?

What are the specifications of IEEE1394?

For the specifications of IEEE1394 itself, please refer to the IEEE1394 specification document.
Due to copyright issues, we cannot post these specifications on our website.

The IEEE1394 specifications can also be viewed on the 1394 Trade Association website through member registration (membership fee required).
The 1394 Trade Association (TA) is a group established to promote the 1394 standard.

Is there an organization that certifies IEEE1394 products?

The 1394 Trade Association holds a "plugfest" four times a year.
By participating in this plugfest, connection compatibility with other companies' products can be tested.
If your product is compatible, you can receive a "Compliant Logo" certificate.

Please see the 1394 Trade Association website for details.

Each node is assigned a unique 64-bit ID, Node_Unique_ID. However, how is node_vendor_id, which forms the higher 24 bits of this ID, determined?

A Company_ID code acquired from the IEEE (Institute of Electrical and Electronic Engineers) must be assigned to the higher 24 bits of Node_Unique_ID.
Please see the IEEE1394 standard (IEEE1394-1995 Section 8.3.2.5.1) for details.
