Q: Can CobraNet be in the same network as AVB?
A: It’s certainly possible to mix CobraNet and non-CobraNet trac on the same
network with no perceived problems. However, this is highly topology and usage
dependent. There’s no guarantee that artifacts wouldn’t occur in dierent use
cases. The CobraNet conductor assumes control and provides scheduling for
all trac on the network. When other trac is present, it may delay delivery
of CobraNet audio packets to the extent that the isochronous (beat) interval is
exceeded. In this case, audio artifacts would likely be heard. For this reason we
strongly discourage our customers from doing so. Segregating AVB trac to
VLAN 2 and placing CobraNet trac on a separate VLAN or bridge/switch is
recommended.
Q: How can I send AVB data between Tesira and third party products?
A: This is dependent on some final ratification of the interoperability standards.
Q: Can I make my existing infrastructure AVB-compliant?
A: AVB is enabled on existing infrastructure with the addition of AVB bridges/
switches and endpoints.
Q: Why is your Netgear® switch so much more expensive than on Amazon®?
A: The Netgear switch available from Amazon or other retailers is the same
model number, but is not AVB-enabled. The Netgear GS724T switch supplied
by Biamp has an AVB software license loaded and enabled on the device. This
is a paid upgrade provided by Netgear to Biamp. This software license is not
available from Netgear to other users.
Q: When is there going to be a video device that uses AVB?
A: AVB data is purely that and is technically video-ready now. There is a
requirement for hardware-based video endpoints. Manufacturers are still
developing hardware to bring to market.
Q: How do I set up VLANs with AVB?
A: AVB trac is sent between AVB devices using VLAN-tagged packets and
the endpoints and bridges act to automatically create and join the appropriate
VLAN.
Q: What form does AVB trac take on my system?
A: By default AVB trac between the talker and listener is tagged trac with a
VLAN ID number of 2.
Q: What cable do I need for AVB?
A: AVB switches work at Gigabit speeds or better. Cat-5e or better cable is
required.
