In computing, a screen buffer is a part of computer memory used by a computer application for the representation of the content to be shown on the computer display. [3] The screen buffer may also be called the video buffer, the regeneration buffer, or regen buffer for short. [4] Screen buffers should be distinguished from video memory.
Some dedicated hardware overlay devices use embedded Linux as an operating system, for example the video logger by Racelogic uses a Texas Instruments DM355 micro-controller to blend a frame buffer containing graphics onto a live video feed, and then store the result in MPEG-4 format on a flash card.
Knoppix booting on the framebuffer. The Linux framebuffer (fbdev) is a linux subsystem used to show graphics on a computer monitor, typically on the system console. [1]It was designed as a hardware-independent API to give user space software access to the framebuffer (the part of a computer's video memory containing a current video frame) using only the Linux kernel's own basic facilities and ...
Buffering and pixelation are the scourge of streaming video. It ruins the experience for viewers, robs advertisers of revenue as said viewers tune out, and causes technical headaches for streaming ...
In computer science, a data buffer (or just buffer) is a region of memory used to store data temporarily while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers); however, a buffer may be used when data is moved between processes ...
Triple buffering Allows high speed applications to perform multi-buffering with less screen flickering and without having to wait for the graphics controller. Refresh rate control using GTF timings This allows applications and operating system utilities to change the refresh rate in a standard way on all VBE 3.0 graphics controllers.
A software implementation of double buffering has all drawing operations store their results in some region of system RAM; any such region is often called a "back buffer". When all drawing operations are considered complete, the whole region (or only the changed portion) is copied into the video RAM (the "front buffer"); this copying is usually ...
Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
