Abstract

An Intelligent Network Peripheral (INP) is equipped with a recording control processor that is connected to at least one internal or external recording device (e.g., hard drive, disk array, CD-recorder, DVD recorder, and/or tape device). Using the INP, a user may be prompted to perform an activity, such as (1) start a new recording session, (2) playback a recorded session, (3) delete a recorded session, (4) edit recording parameters (e.g., the number of stored frames, the length of a session to record, the resolution of the image to record), and (5) re-run a recorded session. An INP may be incorporated into a Keyboard/Video/Mouse (KVM) switch, a Rack Connection Manager (RCM) and/or a Pod Extension Module (PEM) for recording at least one of video from and user input to a computer for diagnostic and other purposes.

Claims21

Dependent claims

A peripheral device enclosed in a housing for intercepting and recording interactions between a user interface device and first and second servers, the peripheral device comprising:

a first computer-side interface for receiving signals corresponding to computer video signals of the first server and for selectively (1) transmitting signals corresponding to changes in state of the user interface device to the first server when the first server is the active server and (2) not transmitting signals corresponding to changes in the state of the user interface device to the first server when the first server is not the active server;
a second computer-side interface for receiving signals corresponding to computer video signals of the second server and for selectively (1) transmitting signals corresponding to changes in state of the user interface device to the second server when the second server is the active server and (2) not transmitting signals corresponding to changes in the state of the user interface device to the second server when the second server is not the active server;
at least one user-side interface for receiving signals corresponding to changes in state of the user interface device and for selectively (1) transmitting signals corresponding to computer video signals of the first server when the first server is the active server and (2) transmitting signals corresponding to computer video signals of the second server when the second server is the active server;
a controller for receiving a switching command for selecting which of the first and second servers is the active server;
and
a recording control processor for recording (1) signals corresponding to computer video signals of the first server when the first server is the active server, (2) signals corresponding to changes in state of the user interface device, (3) a timing correlation between the signals corresponding to computer video signals of the first server and the signals corresponding to changes in state of the user interface device when the first server is the active server, and (4) a timing correlation between the signals corresponding to computer video signals of the second server and the signals corresponding to changes in state of the user interface device sent to the second server when the second server is the active server, and for beginning recording signals corresponding to computer video signals of the second server when the second server is not the active server but a configurable condition occurs on the second server.

A peripheral device enclosed in a housing for playing back recorded interactions between a user interface device and a computer monitor of a user and a first server, the peripheral device comprising:

a first computer-side interface for receiving first signals corresponding to computer video signals of the first server and for selectively (1) transmitting signals corresponding to changes in state of the user interface device to the first server when the first server is the active server and (2) not transmitting signals corresponding to changes in the state of the user interface device to the first server when the first server is not the active server;
a second computer-side interface for receiving signals corresponding to computer video signals of a second server and for selectively (1) transmitting signals corresponding to changes in state of the user interface device to the second server when the second server is the active server and (2) not transmitting signals corresponding to changes in the state of the user interface device to the second server when the second server is not the active server;
at least one user-side interface for receiving second signals corresponding to changes in state of the user interface device and for transmitting signals corresponding to computer video signals of the first server when the first server is the active server and (2) transmitting signals corresponding to computer video signals of the second server when the second server is the active server;
a controller for receiving a switching command for selecting which of the first and second servers is the active server;
and
a recording control processor for playing back third recorded signals corresponding to computer video signals of the second server that was not the active server when the third recorded signals were recorded, wherein at least a portion of the first and third signals are played back for display at the same time.
