The Core Motion framework lets your application receive motion data from device hardware and process that data. The framework supports accessing both raw and processed accelerometer data using block-based interfaces. For devices with a built-in gyroscope, you can retrieve the raw gyro data as well as processed data reflecting the attitude and rotation rates of the device. You can use both the accelerometer and gyro-based data for games or other apps that use motion as input or as a way to enhance the overall user experience.

Core Video provides a pipeline model for digital video. Partitioning the processing into discrete steps makes it simpler for developers to access and manipulate individual frames without having to worry about translating between data types (QuickTime, OpenGL, and so on) or display synchronization issues. Applications that do not need to manipulate individual video frames should never need to use Core Video directly.
