Abstract

Non-coded information (NCI) consists of a compressed and encoded stream of bits which represents information collected by an input device (e.g.) an image scanner of digital voice input). In most cases it is not necessary for this information to be interpreted or manipulated by the application program controlling the devices. The information is sent in the encoded form to an output device in which the stream of bits is decoded and the information presented to the user. The use of tokens for the non-coded information is illustrated in the drawing.

Token For Non-Coded Information

Non-coded information (NCI) consists of a compressed and encoded stream of bits which represents information collected by an input device (e.g.) an image scanner of digital voice input). In most cases it is not necessary for this information to be interpreted or manipulated by the application program controlling the devices. The information is sent in the encoded form to an output device in which the stream of bits is decoded and the information presented to the user. The use of tokens for the non-coded information is illustrated in the drawing.

The functions of receiving, storing, retrieving and presenting the non-coded information are contained in Presentation Services. The application program is presented with NCI tokens for each block of NCI data, each of which tokens uniquely identifies the data and are subsequently passed from the application program to Presentation Services when the data is to be sent to the output devices.

This ensures that the number of movements of the NCI data is minimized. In some systems it may be possible for the Presentation Services and the NCI data base to be in a different node from the application program. The application program is not required to process NCI data which is large and variable in length, but NCI tokens which are relatively short and fixed length. The storage and retrieval of NCI data is under the control of a system program and is independent of any particular application program....
