Video compression (VC)
Real time video compression permits a frame rate of 30 frame/s in any mode at VGA.
The JPEG compression engine is a standard baseline sequential JPEG encoder
[2].
The compression ratio can be modified by applying a multiplication factor on the quantization table.
The quantization table can be scaled from a factor of 1/8 to a factor of 8.
The STV0974 video compression block includes a baseline DCT JPEG encoder compliant with
ISO DIS 10918-1.
The JPEG encoder has the following characteristics:
● baseline sequential DCT based encoder
● YUV 422 encoding only
● up to VGA image size
● scalable quantization table
● standard quantization table
● standard Huffman coder
The encoder top level block diagram is presented in
Figure 3.
The input data is a YUV 422 8-bit data stream in raster order. The output data is a baseline JPEG
data stream.
