HDCP Specification Compliance Test Specification November 18, 2009 Revision 1.2 Intel Corporation / Digital Content Protection LLC HDCP Specification Compliance Test Specification The HDCP Compliance Test Specification uses Pseudo-sinks, Pseudo-repeaters and Pseudo-source TEs to test corresponding source, sink and repeater DUTs. The TEs simulate the behavior of sources, sinks and repeaters and can be configured to test the behavior of the DUTs under normal and error conditions. 1. Transmitter Test Transmitter’s procedure is tested under the following two conditions of connection. Receiver is connected Repeater is connected Note: The source is required to play protected content thus requiring HDCP to be enabled 1A. Downstream procedure with Receiver Transmitter’s downstream procedure with Receiver is tested under the following two conditions of connection. HDMI-capable Receiver is connected DVI Receiver is connected With HDMI-capable Receiver Transmitter’s procedure is tested when it is connected to HDMI-capable Receiver. z In this test, DUT should transmit one of the following video format signals with Data Island period in HDMI mode. - 640x480p@59.94/60Hz - 720x480p@59.94/60Hz - 720x576p@50Hz Page 11 of 140 11
HDCP Specification Compliance Test Specification November 18, 2009 Revision 1.2 Intel Corporation / Digital Content Protection LLC 1A-01. Regular procedure: With HDMI-capable Receiver Test Objective Verify that Transmitter performs the correct HDCP Authentication Protocol with the downstream HDMI-capable Receiver. Required Test Method Connection Setup Connect TE to the downstream HDCP-protected Interface Port of DUT. DUT (Source) HDMI Test Equipment (Pseudo-Sink) Configuration of TE Initial Setting EDID HDMI-capable HDCP port readable (i.e. it can be accessed) Bcaps: REPEATER bit 0 First Part of Authentication Bcaps: 1.1 FEATURES bit 0 Bksv valid value R0’ correctly computed value Third Part of Authentication Ri’ correctly computed value Test Case [Before starting authentication] (STEP TP01) HDCP HPD maps to physical HPD line. TE asserts HDCP HPD. (TE’s Bstatus: HDMI MODE is zero.) (STEP TP02) Confirm the video signal is transmitted to an unauthenticated Receiver DUT reads EDID and begins sending unencrypted video signal by HDMI protocol (i.e. one Data island at least once per two video fields). ¾ If DUT begins the first part of authentication before starting to send video signal, then FAIL. (Refer to ‘Ref-1A-1’) Page 12 of 140 12
HDCP Specification Compliance Test Specification November 18, 2009 Revision 1.2 Intel Corporation / Digital Content Protection LLC (STEP TP03) TE sets Bstatus: HDMI MODE after reception of a Data Island. (STEP TP04) DUT begins the first part of authentication after successful transition to HDMI mode. ¾ If DUT begins the first part of authentication before TE transitions to HDMI mode (i.e. before TE sets Bstatus: HDMI MODE), then WARNING. (Refer to ‘Ref-1A-2’) [First Part of Authentication] (STEP T101) As the first part of authentication protocol, DUT performs the actions below. z Read Bcaps (REPEATER, 1.1 FEATURE) z Read Bksv z Write An z Write Aksv Note: The order of the read access of Bksv and Bcaps does not matter. Bcaps and Bksv may be read after writing Aksv. Note: DUT may start re-authentication at any time. If it happens, TE outputs the actual procedures in order but only uses the last-performed authentication to decide the test result. (STEP T102) The following are considered as errors in the DUT’s operation. Verify the start of the authentication ¾ If DUT does not start the first part of authentication, then FAIL. (Refer to ‘Ref-1A-3’) Verify the timing to write Aksv ¾ If Aksv was written before writing An, then FAIL. (Refer to ‘Ref-1A-4’) Verify Ainfo: ENABLE 1.1 FEATURES ¾ Ainfo: ENABLE 1.1 FEATURES bit was set to one before writing Aksv, then FAIL. (Refer to ‘Ref-1A-5’) Note: TE does not support Advance Cipher and Enhanced Link Verification. (STEP T103) Verify the timing to read R0' TE calculates R0’. DUT reads R0’. This must be attempted later than 100 ms after writing Aksv. ¾ Page 13 of 140 If DUT does not wait at least 100 ms to read R0’ after writing Aksv, then FAIL. 13
HDCP Specification Compliance Test Specification November 18, 2009 Revision 1.2 Intel Corporation / Digital Content Protection LLC (Refer to ‘Ref-1A-6’) (STEP T104) Verify the timing of HDCP Encryption enabled DUT enables HDCP Encryption after reading R0’. ¾ If DUT enables HDCP Encryption before reading the whole two bytes of R0’, then FAIL. (Refer to ‘Ref-1A-8’) [Third Part of Authentication] (STEP T301) TE updates Ri’ for every 128th frame from the first encrypted frame. Verify the timing to read Ri' DUT reads Ri’ at the authenticated state. This is made at the nominal rate of once every two seconds, plus one-half second. ¾ If DUT does not read Ri’ within 3.5 seconds after the previous reading, then FAIL. (Refer to ‘Ref-1A-9’) ¾ If DUT does not read the whole two bytes of Ri’, then FAIL.(Refer to ‘Ref-1A-7’) (STEP TT01) Verify CTLx, Keep-out period, Line Key Calc period The following are considered as errors in the DUT’s operation. ¾ If the encryption enable/disable value (EESS: ENC DIS/ENC EN) is not transmitted during the valid period, then FAIL. (Refer to ‘Ref-1A-10’) ¾ If any Data Island, Video Data, or Guard Band is transmitted during keep-out period, then FAIL. (Refer to ‘Ref-1A-11’) ¾ If any Data Island is transmitted during Line Key Calc period on the encrypted frame, then FAIL. (Refer to ‘Ref-1A-12’) (STEP TT02) Verify HDCP Encryption The following are checked to determine whether HDCP encryption is correctly applied. (Refer to ‘Ref-1A-13’) ¾ Video: if the decrypted and shown image is not considered right visually, then FAIL. ¾ Audio: if any error is detected by decrypting all packets which are transmitted in Data Island period and verifying their BCH ECC, then FAIL. Otherwise, if DUT completes the authentication, PASS. Page 14 of 140 14
HDCP Specification Compliance Test Specification November 18, 2009 Revision 1.2 Intel Corporation / Digital Content Protection LLC 1A-02. Regular procedure: HDCP HPD after writing Aksv Test Objective Verify that Transmitter enters the No Receiver Attached state when HDCP HPD is de-asserted after writing Aksv and then re-starts the authentication after HDCP HPD is asserted by the downstream Receiver. Required Test Method Connection Setup It is same as ‘1A-01 Regular procedure: With HDMI-capable Receiver’. Configuration of TE It is same as ‘1A-01 Regular procedure: With HDMI-capable Receiver’. Test Case [Before starting authentication] described in ‘1A-01 Regular procedure: With HDMI-capable Receiver’ is performed. [First Part of Authentication] (STEP T101) and (STEP T102) of [First Part of Authentication] described in ‘1A-01 Regular procedure: With HDMI-capable Receiver’ are performed. TE sends HDCP HPD to the upstream HDCP-protected Interface Port of DUT. If PCP Source CP&EDID HPD ‘N’, then HDCP HPD maps to physical HPD line. TE pulses the physical HPD signal of the upstream HDCP-protected Interface Port to DUT more than 100ms. If PCP Source CP&EDID HPD ‘Y’, then HDCP HPD also maps to CP&EDID signal (as defined in HDMI 1.4 specification); both cases will be tested. Verify the attempt of re-authentication DUT attempts to re-start the first part of authentication. ¾ If DUT performs the procedures of (STEP T101) described in ‘1A-01 Regular procedure: With HDMI-capable Receiver’ while TE is de-assserting HDCP HPD, then WARNING. (Refer to ‘Ref-1A-14’) ¾ If DUT enables and keeps HDCP Encryption, then FAIL. (Refer to ‘Ref-1A-14’) ¾ If DUT does not perform the procedures of (STEP T101) described in ‘1A-01 Regular procedure: With HDMI-capable Receiver’ once again, then WARNING. (Refer to ‘Ref-1A-14’) Page 15 of 140 15
HDCP Specification Compliance Test Specification November 18, 2009 Revision 1.2 Intel Corporation / Digital Content Protection LLC Note: Among the procedures of (STEP T101), ‘Write An’ and ‘Write Aksv’ must always be performed by the DUT, the DUT is not required to perform the other procedures outlined under (STEP T101) Otherwise, PASS. The following is an acceptable operation by the DUT. ¾ If DUT has no FAIL test results and DUT performs the procedures of (STEP T101) described in ‘1A-01 Regular procedure: With HDMI-capable Receiver’ once again, then PASS. (Refer to ‘Ref-1A-14’) Page 16 of 140 16
