Jackson (Virata) is the A&T WG Chair. B. Dugerdil (Motorola) is the Vice-Chair. The A&T WG presentation to the closing plenary is contained in DSLForum01-230. Joint Architecture/Emerging DSLs DSLForum01-159 (J. Lee, Nokia) discusses a method for carrying data packets over VDSL (PoV) without using AAL5 over a VDSL link. Currently, there are several options for PoV. One option is based on ATM transport mechanism by using AAL5. Current ADSL-based networks also carry IP packets through ATM cells by using AAL5. But the use of ATM incurs additional complexity due to required SAR functions and inefficiency due to high overhead of ATM cells. A transport method without using the ATM layer is possible. In particular, PPP is used to encapsulate IP packets, which in turn are encapsulated into a frame, possibly based on HDLC (See V. Oksman, “G.vdsl: Encapsulation proposal for transport of packets over VDSL [PoV], ITU-T SG15/Q4 CF-057, Clearwater, Florida, January 2001). DSLForum01-159 provides the protocol stacks required for such a method, and discusses one possible encapsulation method and the rationale

Enabling the Digital Media Home Network FOR DISCLOSURE INFORMATION, REFER TO MONTGOMERY & CO.’S FACTS & DISCLOSURES ON PAGES 18 & 19 Digital Media Technology & Wireless Technology May 16, 2007 INVESTMENT SUMMARY The battle for the digital media The battle for superiority in the next great digital media market opportunity—the digital multimedia home network is on. home network—is on. And, like all great digital media markets, this one just makes good intuitive sense. Digital media consumers worldwide have a great appetite for digital content and they have a desire to move that content around the home. We believe that, necessitated by the continuing adoption of the digital video recorder (DVR) and other content storage technologies, accelerated by the rapid ramp of digital and high-definition television technologies, and enabled by the deep pockets of the telcos and cable operators, this market is poised for significant growth over the next several years and represents one of the largest-volume semiconductor opportunities in the digital media component space to date. The digital media networked The digital multimedia home network opportunity has been necessitated by the increasing ability of home—a function of recording... the consumer to record (or download) and display video content. Over the last several years consumers, especially in North America, have grown fond of recording content and storing it to hard drive solutions.
