Abstract: Methods and systems resume workflow processing of a print job at intermediate steps of a print workflow. In one embodiment, a control system initiates processing of a print job based on steps in a print workflow, where the steps identify print shop activities to perform for the print job. The control system identifies an error in executing a step of the workflow, and identifies an intermediate step in the workflow that has executed in processing the print job. The control system identifies an updated file for the print job to correct the error, and resumes the processing of the print job at the intermediate step using the update file.

Abstract: In a video encoder a prediction signal at a bit resolution of P is subtracted from an input signal received at a bit resolution of P+?, where P is typically 8 bits, and P+?, 10 bits. A transform is then performed on the result, the output of which transform being at a bit resolution of at least P+?. The transformed signal is quantised, and the quantised signal used to form the prediction signal. The quantised signal is then coded for downstream delivery. At a decoder, the process is inverted, preserving the extra ? bits input to the encoder.

Abstract: Apparatus and methods for distributing print jobs. A print job is generated at an application node of a network, and has associated therewith print parameters. The print job is routed to a distribution node on the network. The parameters are then parsed from the generated print job and the print job parameterized with predetermined metrics that are a function of at least one of the parsed parameters. The parameterized print job is then routed to a destination device on a destination node on the network.

Abstract: A system for monitoring a plurality of video signals in an internal video network, such as a broadcast recording environment, or security camera network, is described. The system comprises a picture monitor 2 having a screen 6 on which a mosaic video image containing the video signals from a plurality of cameras 28 or other video devices is displayed. Selection of a video signal from the mosaic image can be performed to display a full screen version of that signal. Preferably, at the transmission stage 20 of the network, only the mosaic video image is transmitted. By not transmitting the individual video signals separately, a large saving can be made on the band width required for the transmission as well as on the cost of the encoding components at the transmitter.
