Download:
̵ The copy of content from one computer system to another
̵ Types : progressive download (watch while download), full download
̵ Examples: Purchase of latest singles, podcasts, Apple movie trailer

6. Why streaming rather than download?
̵ Real time functional control
(play, pause, fast forward, rewind, stop)
̵ No need to wait for download to happen
̵ Ability to control bandwidth end to end
̵ Bandwidth Management
̵ Secure Access
̵ Asset Management and control
(view versus takeaway)
̵ Usage reporting (manipulate log files)
̵ Live streaming

7. Why download rather than streaming?
̵ One time bandwidth cost
̵ Playback anytime, any place
̵ Ability to easily redistribute files
̵ Transfer media to other devices
̵ Always get best quality
̵ Usually no firewall issues.

8. 3GPP
̵ 3rd Generation Partnership Project (3GPP)
̵ Collaboration of telecommunication associations (est. 1998)
̵ Aimed at UMTS networks
̵ Latest: 3GPP Release 6 (Release 7 almost finalized, work on
Release 8 is also under way)
3GP
̵ Multimedia container format defined by 3GPP
̵ Simplified version of MP4 container

10. Mobile streaming
̵ Screen Resolution
̵ mobile devices have small screens, and display a reduced resolution
̵ The resolutions typically used are :
CIF (352 x 288), QCIF (176 x 144), SQCIF (128 x 96), HVGA (640
x 240), QHVGA (320 x 240)
̵ Bandwidth
̵ the mobile network offers a more limited
bandwidth and higher latency compared
to a broadband network.
̵ using the IP supports both TCP
and UDP protocols.

11. Mobile streaming architecture

12. iPhone & ipad streaming
̵ Use HTTP streaming only
̵ Allow the bandwidth dynamic adaptation technology Known
as "adaptive bit-rate"
̵ Files are "segmented" in many fragments that the player
invoked with "HTTP GET "
