Start Code Prefix (SCP) H.264 and MPEG-4 Stream contain various codes that are identified by a common 3 byte string = 0x 00 00 01 H.264 SCP Identifies beginning of NAL Unit. Stream Structure: 1. NAL Unit Code - 1 byte 2. NAL Unit Data Anatomy of 1 byte = 8 bits of NAL Unit Code: 1 Bit - Always zero 2 Bits - 0 for non ref frames. Non zero for SPS, PPS and Ref frame. 5 bits - NAL Unit Type. 1 - Non IDR, 5 - IDR, 7 - SPS, 8 - PPS.

==> What is System Programming? System programming is the practice of writing 'system software', which is code that lives at a lower level, talking directly to the kernel and core system libraries. Put another way, system programming deals with system calls and other low-level functions, such as those defined by C library. ==> What are device drivers (in linux)? Device drivers are distinct "black boxes" that make a particular piece of hardware respond to a well-defined internal programmin interface; they hide completely the details of how the device works. User activities are performed by means of a set of standardized calls that are independent of the specific driver; mapping those calls to device-specific operations that act on real hardware is then the role of device driver.
