A/V Player Bridge Selection

• PC to DSP communication is enabled, this means:

– Play lists can be synchronized– Data can be updated

• Time of day / date information, firmware updates, calendars, phone numbers, contact lists, appointments, to do lists, expense entries…the list is endless

– You can add applications that rely on flexible communications between the PC and the DSP

– The result: Your audio player is different than the next one on the store shelf.

• Intelligent battery management when connected to the USB cable

– The USB cable can act as a battery charging unit

– No wall adapter needed– When charging is occurring, the

DSP should be powered off, saving current for battery recharge

– An intelligent bridge can control the power states of the HDD (Active, idle, standby, sleep, off)

– An intelligent bridge can write messages such as “Battery Charging” and “Battery Fully Charged” to the player’s LCD

Why is it important to use a firmware based bridge solution for audio players?
