AV-Link

What are the features of the AV-Link family?

The major feature of our AV-Link family is the built-in DV codec/decoder.

This feature enables easy connection with a DV camcorder, an attractive application that includes an IEEE1394 interface.

The built-in CPU of the uPD72891 and 72893 family allows internal control of the protocol layer that is essential for implementing the IEEE1394 protocol and creating recording media devices such as DVD recorders.

The customer can therefore create applications by controlling the product by commands via an API supplied by NEC Electronics.

The MC-10024 is supplied with a device driver reference, and although the customer has to implement from the protocol layer up, this product lets developers design their sets with a high degree of freedom.

I heard that I must sign a contract when using an AV-Link product. How do I go about doing this?

Before using the uPD72891 and MC-10024, you must conclude a license agreement with the DTLA (Digital Transmission Licensing Administrator).

Please see this website for details.

How is the built-in DV codec/decoder controlled?

The AV-Link family' s built-in DV codec/decoder is basically controlled internally.

AV-Link is a simple interface in which the only settings that have to be made from the application layer are the initial settings and operating mode settings (boundary condition settings such as exception processing (mute operation)).

The input data can be scanned and processing executed such as changing to a more detailed operating mode, but to do this, real-time response characteristics are required for the interrupt signals, which are generated in frame units.
