  1. 1. The Digital Media Project Source L. Chiariglione Date 2006/12/17 Title IPTV Requirement Analysis for MAFs No. 0896/Tokyo IPTV Requirement Analysis for MAFs 1. Introduction The columns in the table below are used to represent the following information. • Source and #: requirement source and numbering, e.g., IIF.ARCH.CONTEXT.01. • Requirement: capture of each requirement • MAF Relevance: “yes”, “no”, or “N/A”, and any explanation. • MAF Coverage: When a requirement is MAF relevant, declare if an MAF should cover the requirement or not. When not, explain why. • Existing MAF Support (MS, DMB, …): list how existing MAFs with MS and DMB in particular meet or support the requirement. Requirement Sources: • m134291. ATIS/IIF Architecture and DRM requirements, Montreux, CH. April, 2006. Currently, this document contains AITS/IIF requirements on Architecture in Section 2 and DRM interoperability in Section 3. 2. ATIS/IIF Architecture Requirements

Source and # Requirement MAF MAF Existing MAF Relevance Coverage Support (MS, DMB, …) IIF.D.GN.100 The IPTV security solution shall be scalable Yes to support protection of content that is distributed simultaneously to a very high number of subscribers. IIF.D.GN.200 The IPTV security solution shall support Yes protection of content that is transferred over multicast channels and/or over unicast streams. IIF.D.GN.0300 The IPTV security solution shall make Yes possible rights specifications and protect content for multiple common existing content formats (e.g., MP-3, MPEG-4, etc.) and/or common computing platforms. IIF.DRM.GN.0400 For certain content types (such as movies that Yes are stored on a PVR) the IPTV security solution may provide stronger cryptographic measures to protect against theft. IIF.DRM.GN.0500 As rights allow, the IPTV security solution Yes should allow the end user to change an IPTV Receiving Device without inherently affecting his/her rights to consume content. IIF.DRM.G.0600 The IPTV security solution shall support It depends on what is multiple DRM systems. the mening of DRM systems. IIF.D.GN.0600-01 The IPTV security solution shall support at Outside of MS MAF 00 least one standardized scrambling algorithm (hereafter referred to as “IPTV Common Scrambling Algorithm”) to protect video transport stream packets. IIF.D.GN.0600-02 The specification of an IPTV scrambling Outside of MS MAF 00 algorithm shall not preclude activation of the scrambling algorithm in the field. IIF.D.GN.0600-03 The IPTV security solution shall provide a Yes 00 mechanism to signal the IPTV Receiving Device to utilize a specified scrambling algorithm based on a standardized framework. IIF.D.GN.0600-04 The IPTV security solution shall have the Outside of MS MAF 00 ability to use standard key management systems (e.g., MIKE, EMM/ECM), to the extent that this is required for interoperability.
