OSDs display graphical information superimposed over the picture, which is done by synchronizing the reading from OSD video memory with the TV signal. Some of the first OSD-equipped televisions were introduced by RCA in the late 1970s, simply displaying the channel number and the time of day at the bottom of the screen.
On-screen display, a feature of visual devices like VCRs and DVD players that displays program, position, and setting data on a connected TV or computer display Open Source Definition , criteria used by the Open Source Initiative to determine whether or not a software license can be considered open source
Display Control Channel (DCC) is an advanced method of implementing on-screen display (OSD) technology on KVM switches. It was developed and patented by ConnectPRO, a company that has been providing KVM and networking solutions since 1992.
Extended Display Identification Data (EDID) and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).
The Xterm terminal emulator. In the early 1980s, large amounts of software directly used these sequences to update screen displays. This included everything on VMS (which assumed DEC terminals), most software designed to be portable on CP/M home computers, and even lots of Unix software as it was easier to use than the termcap libraries, such as the shell script examples below in this article.
Byobu is an enhancement for the GNU Screen terminal multiplexer [2] or tmux [3] used with the GNU/Linux operating system that can be used to provide on-screen notification or status, and tabbed multi-window management. It is intended to improve terminal sessions when users connect to remote servers.
A Network Computing Devices NCD-88k X terminal An X server runs on the X terminal, connecting to a central computer running an X display manager. In this example, client programs (xterm and xedit) are running on the same computer. In computing, an X terminal is a display/input terminal for X Window System client applications.
Each window is represented by a character matrix. The programmer sets up the desired appearance of each window, then tells the curses package to update the screen. The library determines a minimal set of changes that are needed to update the display and then executes these using the terminal's specific capabilities and control sequences.
