Abstract

A data decoding system that includes a server-side proxy component and at least two back-end computers, where the server-side proxy component is configured, when it receives a decoding request from a client, to select a back-end computer to forward the decoding request to, based on either a pre-defined rule, load estimates for said at least two computers, estimated network throughputs across network paths to the two computers. In response to receiving this request, the back-end computer that is selected is configured to decode the request, which is an image of decodable indicia, by locating the decodable indicia within the image and decoding it into a decoded message. The decodable indicia was provided by a raw image byte stream, a compressed image byte stream, or a partial compressed image byte stream.

Claims5

Dependent claims

A data decoding system comprising a server-side proxy component and a back-end computer;

wherein said server-side proxy component is configured, responsive to receiving a decoding request from a client, to select the back-end computer to forward said decoding request to, based on one or more of:
a pre-defined rule, load estimates for the back-end computer, estimated network throughputs across network paths to the back-end computer;
wherein said selected back-end computer is configured, responsive to receiving said decoding request, said decoding request comprising an image of decodable indicia, to locate said decodable indicia within said image;
wherein said selected back-end computer is further configured, responsive to successfully locating said decodable indicia, to decode said decodable indicia into a decoded message;
and
wherein said image of decodable indicia is provided by one or more of:
a raw image byte stream, a compressed image byte stream, a partial compressed image byte stream.
