1. STREAMING VIDEO TECHNIQUES
Solution: In answer to this problem, Iviewit developed techniques that can be
generally described as a method of playing a digital video file over a network
includes providing a digital video file from a first storage device; downloading a
first portion of the digital video file from the first storage device, and behind
the broadcast, over a network to a computer having a second storage device
and a display screen; expanding the viewing frame size of the computer display
screen to at least 640 x 480 pixels; and playing the first downloaded portion on
the expanded display screen from the second storage device while
substantially simultaneously downloading a second portion of the digital video
file to the second storage device.
Problem: In the field of streaming video, the primary design challenge was that
the viewer desires perfect video quality over a limited bandwidth network.
Perfect video quality requires an enormous amount of digital data. It was
known to capture video using a capture device, compress the resulting
captured video, store the compressed video, and send the compressed video
across the TCP/IP protocol. However, prior attempts had failed to produce
high quality streaming video, and failed to produce full screen, full frame rate
video at any acceptable quality.

2. The capability in doing such requires: (i) Receiving a digital video file; (ii)
Encoding the received digital video file using a video encoder; (iii) Associating a
viewing frame size of at least 320 x 240 pixels with the encoded digital video
file; (iv) Uploading the digital video file to a network server; and In response to
a user request, streaming the digital video file across the TCP/IP protocol.
