HAVi
HAVi architecture
1394 Communication media manager : synchronous and asynchronous communication
Messaging System : passes messages
Registry : Directory service
Event Manager : Event delivery service
16-08-10 9
HAVi
Stream Manager : real time transfer of AV
Resource Manager : sharing of resources
Device Control Module(DCM) : Control
DCM Manager : installation and removal of DCM code units
Managing needed to prevent conflict between devices

HAVi
FIREWIRE IEEE 1394 standard , Apple Commuters
Data transfer rates of 400 Mbps (and more)
connects upto 63 devices without needing hubs
Isochronous protocol
plug and play
Addresses 64 bit address space
16-08-10 11
HAVi
WORKING
Locate FAV or IAV
Upload DCM
Install :I. Device Control modules for device II. Functional Component Modules for each component
of the device

CLASSIFICATION OF HAVi DEVICES
16-08-10 13
HAVi
Runs all elements of the HAVi architecture
Runs Java code uploaded from other devices
They can act as controllers for other HAVi devices
examples: set top boxes, TV’s, PC’s
16-08-10 14
FULL AV DEVICES
HAVi
INTERMEDIATE AV DEVICES (IAV)
Cannot run Java bytecodes
Special purpose controllers for some devices
examples: Home theatre amplifiers or DVD players
16-08-10 15
HAVi
BASE AV DEVICES
Can store Java bytecode and upload it to a FAV
Controlled by code running on the FAV
Examples: Portable audio players, camcorders
16-08-10 16
HAVi
LEGACY AV DEVICES (LAV) Devices that already exist and are avilable
with users
Do not recognize HAVi architecture
Firewire and Non-Firewire
16-08-10 17
HAVi
ADVANTAGES
Interoperability
Brand Independence
Linked to the past , upgradable in the future
Hot “plug and enjoy”
16-08-10 18
HAVi
DISADVANTAGES Firewire complicated to implement
Data formats of devices different
Spread of viruses
very high price
16-08-10 19
HAVi
FUTURE SCOPE LINUX as operating system and JAVA as
programming language
Connecting HAVi to other networks
16-08-10 20
HAVi
CONCLUSION
Future of home networking
HAVi – the only standard capable of exploding AV capabilities
