Abstract
IN a system on chip (SoC) for adaptively adjusting a bit rate, the SoC includes a central processing unit (CPU) configured to compare a first reference bit rate with a bit rate of a previous frame and to output a first parameter, a spatial filter configured to adjust a cutoff frequency using the first parameter, to filter high-frequency components from a current frame using an adjusted cutoff frequency and to output a filtered current frame, and a video codec configured to adjust a bit rate of a current macroblock in the filtered current frame using a second parameter generated according to a result of comparing a second reference bit rate with a bit rate of a previous macroblock in the filtered current frame.

A system on chip (SoC) comprising:
- a central processing unit (CPU) configured to compare a first reference bit rate with a bit rate of a first frame and to generate a first parameter;
- a spatial filter configured to adjust a cutoff frequency using the first parameter, to filter high-frequency components from a second frame using the adjusted cutoff frequency, and to output the filtered second frame;
- and
- a video codec configured to adjust a bit rate of a second macroblock in the filtered second frame using a second parameter generated based on a result of comparing a second reference bit rate with a bit rate of a first macroblock in the filtered second frame.
A data processing system comprising:
- a memory device configured to store a plurality of frames including a first frame and a second frame;
- a camera;
- a display device;
- and
- a controller configured to control the memory device, the camera and the display device,
- wherein the controller is configured to compare a first reference bit rate with a bit rate of the first frame, to generate a first parameter, to adjust a cutoff frequency using the first parameter, to filter high-frequency components from the second frame using the adjusted cutoff frequency, and to adjust a bit rate of a second macroblock in the filtered second frame using a second parameter generated according to a result of comparing a second reference bit rate with a bit rate of a first macroblock in the filtered second frame.
A system on chip (SoC) comprising:
- a central processing unit (CPU) configured to compare a reference bit rate with a bit rate of a previous frame and to generate a parameter;
- a spatial filter configured to adjust a bit rate per frame and to filter predefined frequency components from a current frame;
- and
- a video codec configured to adjust a bit rate per macroblock included in the filtered current frame.
