HAVi ARCHITECTURE

Vendor specific hardware and software Application Programming Interface(API)

IEEE 1394 as connecting medium

Media Manager and messaging system

16-08-10 7

HAVi

Contd… Software modules :1. Registry2. Event Manager3. Stream Manager4. Resource Manager5. Device Control Modules (DCM)6. DCM Managers

16-08-10 8

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
