The Home Digital Multimedia Network"The PC is going to be the place where you store the information and really the center of control“ - Bill Gates CES 1/2001 Gordon Bell Microsoft Research Gbell@microsoft.com www.research.microsoft.com/~gbell
The Home Digital Multimedia Network Vision: All digital content. IP on everything. All listening/viewing stations will be digital. In the 10+year, short-term, Digital Transformers convert IP to legacy analog devices. Today Digital Transformers = computers!

Cyber All, a 1 Tbyte, lifetime PC: Cyberizing everything…I’ve written, said, presented (incl. video), photos of physical objects & a few things I’ve read, heard, seen
"The PC is going to be the place where you store the information and really the center of control“ Billg 1/7/2001 Cyberall is an “on-going” project to “cyberize” all of personal bits! • Memory recall of books, CDs, communication, papers, photos, video • Photos of physical object collections • Elimination of all physical stores & objects • Content source for media display: ambiance, entertainment, communication, interaction Goal: to understand the 1 TByte PC: need, utility, cost, feasibility and tools.

Imagine the “killer app” for: The One Tbyte, Lifetime, PC • CyberAll convinces me of a lifetime memory! • Epaper is a great addition to the vision! The most significant Office™ addition since HTML. • Technology to support the vision: • Guarantee that data will live forever! • A single index that includes mail, conversations, web accesses, and books! • E-book…e-magazines reach critical mass! • Telephony and audio capture are needed • Photo & video “index serving” • More meta-information … Office, photos • Lots of GUI to improve ease-of-use
Tools, time, and cost • Scanners: HP Digital Sender, flat beds with ADF, HP photo; fast one to come • Photos: $1 or 0.5-5 min. Large posters: ~ 1-5 hr.Artifacts: ~ 10 min. including photo • Scanning to TIF, PDF: <1 min/page • OCR: for E-Paper or PDF: ~3 pages/min • OCR: for editing 10 min/page! • Books: scanned at CMU ($100/book)
Tools • Acrobat*, Paperport* 6, Omnipage 10 • Indexing Service & Enfish (indexer/search) • Conversion of DEC 8” floppies • “Doubles” to reduce redundancies *Microsoft epaper can replace these!

Connecting computers to receivers, TV sets and/or large monitors • TANSTAAFL* for wiring, monitors, computers*There ain’t no such thing as a free lunch! • CAT5+ @100-10K Mbps is the best, fungible audio, telephony, IP, and video net. CATV is still required, but need not be with the right device! • Computer & HDTV monitors replace TV setsTV sets: unacceptable for browsing & mail… fixable • Every viewing or listening place requires a computer or “digital transformer” for control and Digital to legacy analog (radio mouse gives location flexibility)
