version of a file may be provided at a high cost, in terms of network
resources and latency in reception of the file or, at the user's option, a
smaller, lower resolution, version of the file may be provided with a
corresponding savings in such costs." (Col. 5, ll. 57-61.)
2. Acharya teaches that Web pages are predominately graphical and that
large graphical files slow the response time for Web users. (Col. 2, ll.
34-38.) This delay, called "latency," is primarily a function of the size
of the file and the bandwidth of the connection over which the file is
transmitted. (Col. 2, ll. 39-41.)
3. Acharya explains that latency is a reason that users desire control over
the selection and downloading of files. "As a result of latency, users
are likely to welcome an option to retrieve a lower quality, smaller
version of a file, provided that the file can be provided relatively
quickly, i.e., with savings in latency." (Col. 3, ll. 62-65.) Also,
"[m]any users would likely choose to reject some image or document
files, receive a lower resolution version of others fairly quickly, and
would be willing to wait longer for a higher resolution version of
others." (Col. 4, ll. 9-12.)
4. Acharya also explains that there are other reasons that users desire
control over the selection and downloading of files. "[A]part from
