Panasonic ART -- DTCP HDCP Emulator Mode Explanation Updated Explanation November 2008
Panasonic ART • Review of basic DTCP HDCP Emulator Mode approach – Ensures localization – uses DTCP localization specifications – Preserves (and implements) HDCP revocation system – Equals (or surpasses) HDCP protection levels • Uses AES 128-bit encryption • Uses HDCP robustness rules – Requires “display only” transmission, using implicit copy never (as does HDCP) – HDCP Content Participants and DCP, LLC given third party beneficiary rights to enforce requirements of ART • New Panasonic ART elements – HDCP Licensee as ART proprietor – Single Licensed Product Requirements 2
Panasonic ART -- DTCP HDCP Emulator Mode Explanation 1. The Panasonic ART would utilize DTCP “HDCP Emulator Mode” which is • limited to AES 128 implementations of DTCP • defined using a separate new cipher algorithm (using this newly created system, not CCI or CMS but similar scheme to CMS) 3
Panasonic ART -- DTCP HDCP Emulator Mode Explanation 2. The KSV flow would work as follows: • An HDCP Transmitter would initiate a proposed transmission sequence by seeking the HDCP KSVs from the initial receiving HDCP Receiver. • The HDCP Receiver, knowing that it was going to retransmit the content to the Panasonic ART Source Function, would request that Panasonic ART Source to obtain the HDCP KSVs from all downstream HDCP Receivers. 4
Panasonic ART -- DTCP HDCP Emulator Mode Explanation • The Panasonic ART Source Function would then provide the HDCP KSVs to the initial receiving HDCP Receiver for transmission back to the originating HDCP Transmitter. • Content would be provided to the initial receiving HDCP Receiver by the originating HDCP Transmitter only if all HDCP KSVs are valid and non-revoked. 5

Panasonic ART -- DTCP HDCP Emulator Mode Explanation 3. Once Step 2 has been successfully completed, the content flow would work as follows: • Content would flow from the initiating HDCP Transmitter to the initial receiving HDCP Receiver and then internally from that HDCP Receiver to a Panasonic ART Source with a secure indication that it is to be handled using only the “HDCP Emulator Mode.” 7
Panasonic ART -- DTCP HDCP Emulator Mode Explanation • The Panasonic ART Source would then securely determine that the Panasonic ART Sinks that would receive the content are only those that had supplied the HDCP KSVs in Step 2 and that are operating in HDCP Emulator Mode. • The Panasonic ART Sink would supply content only to those HDCP Receivers that supplied KSVs or to internal displays (per normal robustness rules for decrypted HDCP Content). 8
Panasonic ART -- DTCP HDCP Emulator Mode Explanation • The number of Panasonic ART Sinks (and thereafter HDCP Receivers) that would be permitted to receive content from the Panasonic ART Source in the HDCP Emulator Mode would be limited to the normal number of DTCP Sinks permitted to receive from a single DTCP Source, 34, since that number is far less than the number of HDCP Receivers that may receive HDCP Content from an HDCP Transmitter. 9
Panasonic ART -- DTCP HDCP Emulator Mode Explanation 4. The HDCP Emulator Mode of DTCP would be subject to separate • Specification (ensuring that the HDCP Emulator Mode is clearly set out as a separate functionality) • Compliance Rules (ensuring that the process described above is spelled out clearly and separately from other DTCP functions) 10
Panasonic ART -- DTCP HDCP Emulator Mode Explanation • Robustness Rules (matching those of HDCP where there are any differences from the normal DTCP Robustness Rules) • Licensing (e.g., through an Addendum to the DTCP Adopter Agreement) 11
Single Licensed Product Requirements • Previously, there was confusion on this point, – This is not part of ART objective criteria – Must be inferred from provision in Compliance Rules – Not entirely clear what this actually means, since an ART necessarily uses another technology as a bridge between an HDCP Source and either an HDCP Sink or a display • Current proposal meets this issue as described below 12
Single Licensed Product Requirements • Will consist of Initiating, Repeater, and Sink Products paired on a transmission-by-transmission basis – All Products will be Licensed HDCP Products – All Products will be Licensed DTCP Products – When connected using DTCP HDCP Emulator Mode technology, will be paired as a Panasonic ART Single Licensed Product pursuant to the HDCP Compliance Rules • Legal responsibility for each pairing will be clearly placed with the Initiating Product (and its manufacturer/licensee), regardless of the manufacturer of the Repeater and Sink products 13
Single Licensed Product Requirements • Initiating Product will be required to be manufactured under separate license, from DTLA to Panasonic • Panasonic, of course, will produce Initiating Products • Panasonic will also be permitted to sublicense to other manufacturers, which will be permitted to make Initiating Products on the same terms and conditions 14
Single Licensed Product Requirements • Repeater and Sink products will be licensed by DTLA based on the previously drafted DTCP HDCP Emulator Mode documents, with the following critically important differences – Licensees will be required to agree that the Initiating Product is responsible for each ART pairing and that each ART pairing is a Single Licensed [HDCP] Product that is, as such, subject to HDCP requirements as well as DTCP HDCP Emulator Mode requirements – Licensees will be required to register their products (nature of product, model numbers, names of products) with Panasonic 15
Single Licensed Product Requirements – Producers of Initiating Products will be given third party beneficiary rights to enforce the DTLA license requirements on Repeater and Sink products, including seeking an injunction to prohibit further sale and distribution of both noncompliant products and products that are not registered with Panasonic – Licensees making Repeater or Sink Products will indemnify Panasonic and other Initiating Product manufacturers for any damages or other costs associated with failure by any Repeater or Sink Product to comply with the HDCP and/or DTCP Emulator Mode requirements 16
Single Licensed Product Requirements • “Pairing” – Pairing between HDCP Emulator Mode products will be done using special authentication mechanism, unique to the Panasonic ART – Responsibility for pairing, as with the overall functioning of each ART, will be placed on Initiating Product, with manufacturer of an Initiating Product being legally responsible for any failure by any ART (or any component of an ART) to comply with any of the requirements for the ART, including HDCP Compliance Rules 17
