Abstract

This specification defines some common media features for describing

image resolution, size, color, and image representation methods that

are common to web browsing, printing, and facsimile applications.

These features are registered for use within the framework of [REG].

1. Introduction

This work was originally motivated by the requirements from web

browsers to send the browser's display characteristics to the web

server to allow the server to choose an appropriate representation.

This specification defines some common media features [REG] by which

a recipient may inform a sender as to the characteristics of its

message handling. The sender may then provide the variant of the

message that is most suitable for the recipient.

Different variants would typically be higher or lower resolution

images (for example) as appropriate. In the case of a sending to a

printer, the result would be higher quality output. In the case of a

small screen device (cellphone, portable digital assistant), the

result would be faster transmission.

Media features may be used in many different protocol situations.

Those defined in this specification can indicate the display or

printer dimensions, resolution, color capability. The physical

dimensions of a display may be inferred from the display size and

display resolution. In the case of paper output, the paper size may

be expressed as a token from a list of standard paper sizes. These

are presented formally in the Notation...
