Digital Cam Corders <ul><li>The new digital Prosumer cameras have much higher quality, but still some problems </li></ul><ul><li>Recording time limits </li></ul><ul><ul><li>Usually 1 hour for consumer cameras, OK for some applications, but unacceptable if there is no break to change media </li></ul></ul><ul><li>Blair Witch Project – First major movie to be shot with Digital Camera </li></ul>
  6. 6. Cost Dropping quickly Applications expand <ul><li>Until recently, needed a > $10K Sony beta max for decent video </li></ul><ul><li>Now $2,000 digital cameras give comparable quality (and MUCH smaller and lighter) </li></ul><ul><li>Inexpensive disk drives now offer capacity to deal with “raw” video (100MB per minute, 6 gigabytes for an hour) </li></ul><ul><li>Need fast processors to encode, decode, transfer data </li></ul>
  7. 7. More hardware advances <ul><li>IEEE 1394 – “Firewire” standard </li></ul><ul><ul><li>Allows direct connection of digital devices without a separate card </li></ul></ul><ul><li>USB – Universal Serial Bus </li></ul><ul><ul><li>Offers 12Mbit transfer </li></ul></ul><ul><ul><ul><li>Next version will be 100 Mbit </li></ul></ul></ul>
  8. 8. Networking Advances <ul><li>100 Mbit ethernet – Allows streaming of MPEG Video </li></ul><ul><li>“ Switched” Ethernet – allows a separate stream to each individual PC without collisions </li></ul><ul><li>Multicasting router capabilities allow listeners to share a stream </li></ul><ul><li>Cable Modems, ADSL, Satellite Dishes much higher bandwidth to home, small business </li></ul><ul><li>TCP/IP v6 – Quality of Service support </li></ul><ul><li>Internet 2- 600Mbit connections </li></ul><ul><li>Gigabit switches to handle traffic </li></ul>
