Abstract

A method for improving video quality of a video stream. The method decodes the video stream and generates subblocks of video data from the video stream. The method then removes effects of subblock boundaries from previous deblocking. Each subblock is then smoothed to create pixel values and optionally, subblocks are merged if a predetermined quality is not achieved from the smoothing analysis. The pixels values are filled into each pixel position in the subblock. The subblocks are deblocked and then at least one subblock is outputted to a rendering device.

Claims

1. A method for producing an option menu for display on a video monitor in a computer management system to facilitate selection and control of any of a plurality of remote devices from a user workstation of the type including a keyboard, cursor control device and video display, said method performed by a processing of an option n menu circuit and comprising the steps of:

sending control signals and synchronization signals to a plurality of first on-screen display circuits;

sending control signals and synchronization signals to a plurality of second on-screen display circuits;

receiving first red, green and blue digital video signals generated by each of two or more-of said first on-screen display circuits that represent an option menu for display on said video display;

receiving second red, green and blue digital video signals generated by said second on-screen display circuits that represent a cursor within said option menu, said cursor for use in selecting an item from said option menu;

selectably combining the first red, green and blue digital video signals generated by each of said two or more first on-screen display circuits according to a mode index of the display to form a non-cursor portion of the option menu;

combining the selectively-combined first red, green and blue digital video signals of the first on-screen display circuits with the second red, green and blue digital video signals generated by the second on-screen display circuits; and

transmitting a single, combined red, green and blue digital video signal for conversion and display on the display of the user workstation.

2. The method according to claim 1, wherein a user can select any one of said plurality of remote devices for control from said option menu.

3. The method according to claim 1 wherein a user can select any one of said plurality of remote devices from said option menu to view a status of said remote device.

4. The method according to claim 1, wherein a user can select any one of said plurality of remote devices from said option menu to perform diagnostics on said remote device.

5. The method according to claim 1, wherein said received first digital video signals include horizontal and vertical synchronization signals.

6. The method according to claim 1, wherein said one or more second on-screen display circuits comprises a plurality of second on-screen display circuits and said step of producing a cursor within said option menu further comprises the steps of:

generating an outline of said cursor by a first one of said second on-screen display circuits; and

generating a body of said cursor by a second one of said second on-screen display circuits.

7. The method according to claim 1, wherein

the selectably-combined first red, green and blue digital video signals generated by each of said two or more first on-screen display circuits produce an increase in at least one of available colors or characters to be displayed on the display of the user workstation as compared to a video output from a single one of the on-screen display circuits.

8. A method for facilitating selection and control of a plurality of remote devices from a workstation of the type including a keyboard, cursor control device and a video display, said method comprising the steps of:

(a) preparing an option menu by an option menu circuit to display a list of a plurality of remote devices on a video display and a cursor for selecting the remote device from the option menu;

(b) selecting a remote device from the list of the plurality of remote devices displayed on the video display by the option menu circuit;

(c) generating keyboard and cursor control device signals in response to said selecting step, said signals indicating the selection of said remote device;

(d) transmitting said signals to said remote device through a switch device; and

(e) receiving video signals from said selected remote device through said switch device, wherein said preparing step further includes the steps of;

receiving first red, green and blue digital video signals generated by each of a plurality of first on-screen display circuits that represent an option menu for display on said video display,

receiving second red, green and blue digital video signals generated by one or more second on-screen display circuits that represent a cursor within said option menu,

selectably combining the first red, green and blue digital video signals generated by each of said plurality of first on-screen display circuits according to a mode index of the display to form a non-cursor portion of the option menu;

combining the selectively-combined first red, green and blue digital video signals of the first on-screen display circuits with the second red, green and blue digital video signals generated by the second on-screen display circuits; and

transmitting a single, combined red, green and blue digital video signal for conversion and display on the display of the user workstation.

9. The method according to claim 8, wherein a plurality of configurations of option menus may be selectively produced by said plurality of first on screen display circuits.

10. The method according to claim 8, wherein:

the selectably-combined first red, green and blue digital video signals generated by each of said plurality of first on-screen display circuit produce an increase in at least one of available colors or characters to be displayed on the display of the user workstation as compared to a video output from a single one of the on screen display circuit.
