The literature of cryptography has a curious history. Secrecy, of course, has always played a central role, but until the First World War, important developments appeared in print in a more or less timely fashion and the field moved forward in much the same way as other specialized disciplines. As late as 1918, one of the most influential cryptanalytic papers of the twentieth century, William F. Friedman’s monograph The Index of Coincidence and Its Applications in Cryptography, appeared as a research report of the private Riverbank Laboratories [577]. And this, despite the fact that the work had been done as part of the war effort. In the same year Edward H. Hebern of Oakland, California filed the first patent for a rotor machine [710], the device destined to be a mainstay of military cryptography for nearly 50 years.

H.264/AVC, the result of the collaboration between the ISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group, is the latest standard for video coding. The goals of this standardization effort were enhanced compression efficiency, network friendly video representation for interactive (video telephony) and non-interactive applications (broadcast, streaming, storage, video on demand). H.264/AVC provides gains in compression efficiency of up to 50% over a wide range of bit rates and video resolutions compared to previous standards. Compared to previous standards, the decoder complexity is about four times that of MPEG-2 and two times that of MPEG-4 Visual Simple Profile. This paper provides an overview of the new tools, features and complexity of H.264/AVC.

A heap is a binary tree satisfying the following conditions: This tree is completely balanced. If the height of this binary tree is h, then leaves can be at level h or level h-1. All leaves at level h are as far to the left as possible. The data associated with all descendants of a node are smaller than the datum associated with this node.

数据异常处理。The main source file is "dabort.s": with suitable -PreDefines or a corresponding "options-setting" file, it assembles to the data abort veneer. This is described in detail in the documentation. The "dabort.h" file contains definitions of some constants used in the data abort veneer s interface to the rest of the system - again, this is described in the documentation. The "option.s" file is an example "options-setting" file.
