Why is ACC better than MPEG-4 or MJPEG?
ACC, Active Content Compression, is the American Dynamics compression approach. The ACC approach is to take a middle ground between image differencing (simple) and motion prediction (expensive). It is a proprietary compression and will often be compared to Motion JPEG and MPEG-4 (H.320) which are standard compressions. ACC has been optimized for surveillance, analysis, transmission, and recording. It is efficient, scaleable, low latency, software-based, and optimized for security applications. Advantages compared to MJPEG or MPEG-4: • ACC has better picture quality than MPEG4 and MJPEG-4 • ACC has better compression that MJPEG • ACC is 4x cheaper than MPEG-4. A current MPEG-4 system requires a dedicated TI DSP. 4 ACC streams can be processed on a single DSP. • ACC is proprietary. We are providing solutions to the security industry. The compression technique needs to be secure as well. Hypothetical: “What happens the first time MPEG-4 or MJPEG are thrown out of a court case because they
