  • 1. Home Information Management Services Art Harvey Broadband Networks Research Labs [email_address]
  • 2. Practicality Intrudes <ul><li>Vision: </li></ul><ul><ul><li>The presence of a home network will enable creation of many new applications and services </li></ul></ul><ul><ul><ul><li>Such as Home Information Management Services </li></ul></ul></ul><ul><li>Reality: </li></ul><ul><ul><li>I encounter difficulty in simply adding devices and software to my home PC and in keeping the PC operating. Imagine life with a home network </li></ul></ul>
  • 3. The Real Topic of this Talk <ul><li>Challenges of making home networks easy to install, use and maintain </li></ul><ul><li>Industry efforts to address this problem </li></ul><ul><li>Our approach to these issues </li></ul><ul><li>Home Information Management Services </li></ul><ul><ul><li>An application that addresses an emerging need and illustrates how we think Home Networks should behave </li></ul></ul>
