"How many bits per picture element does a display need?" For the display resolutions now commonly in use, only 4 bits per picture element (pel) are needed for the display of monochrome images. A total of 8 bits per pel are needed for color images. These conclusions are based both on experiment and on the theoretical model of the visual system in which the detectors in the eye are treated as sim...

Segmented Information Dispersal (SID) Data Layouts for Digital Video Servers

ÐWe present a novel data organization for disk arraysÐSegmented Information Dispersal (SID). SID provides protection against disk failures while ensuring that the reconstruction of the missing data requires only relatively small contiguous accesses to the available disks. SID has a number of properties that make it an attractive solution for fault-tolerant video servers. Under fault-free condit...

Challenges for Information Society ∗

The paper summarizes selected problems related to the fast proliferation of networked computing which is recognized as a beginning of the information era, and the corresponding future needs of Information Society. One domain of new research challenges pertaining to the needs of Information Society, namely modeling is discussed in more detail.

Information Assembly for Adaptive Display

In a world where information is increasingly delivered to users via different devices with dramatically different constraints and capabilities, it is becoming crucial to consider how the presentation of information must be adapted to suit specific devices and user contexts. To avoid confusing and disorienting the users as they switch between devices, the content and structure of information sho...
