Preliminary specification
PDI1394L41
1394 content protection AV link layer controller
2000 Dec 01
10
Port Dir
AVxREADY
Description
Transmit
Out
The L41 is prepared to receive a byte. The attached device will not assert AVVALID for any cycle in which
AVxRDY is false.
Receive
In
The attached device is prepared to receive a byte. The L41 will not assert AVxVALID for any cycle in which
AVxREADY is false.
When the AV port is configured as a receiver, the AVxSYNC signal will be asserted as soon as the PDI1394L41 AVx port has an application
packet available for delivery (independent of AVxREADY) and will remain asserted until the first byte of the application packet is clocked from
the AV port.
12.2.4
Content Protection
The AV Layer incorporates features to implement the Digital Transmission Copy Protection (DTCP) scheme that is specified by the Digital
Transmission Licensing Authority (DTLA). The DTCP specification consists of two primary functions: stream ciphering and authentication. Refer
to
“5C Digital Transmission Content Protection Specification – Volume 1” for more details about the DTCP scheme.
On the AV Link stream ciphering is accomplished by internal 56 bit M6 content cipher and decipher blocks. To ease software development effort
and reduce the loading on the controlling processor, the link chip also includes a cryptographic accelerator capable of doing elliptic curve
multiplications and Sign and Verify operations.
Due to the size and number of operands for the M6 and cryptographic accelerator blocks, the host interface register set has been extended to
provide additional control and data registers. These extensions have been implemented via an indirect addressing mechanism. This mechanism
allows software written for previous versions of the AV Link (PDI1394L21 and PDI1394L11) to operate on the PDI1394L41. Note, however, that
some extensions to the interrupt registers were made to accommodate interrupts originating from the content protection block.
For a full description of the use of the L41’s content protection features please see data sheet addendum AL41–1. AL41–1 addendum can be
requested from Philips by DTLA licensees by e-mailing
1394@philips.com. One paper copy of this addendum is available to each DTLA
licensee after verification of license status. Please see Section 2.1 of this data sheet for further information. DTLA license information is
available at http://www.dtcp.com.
