A security flaw in a software player exposed some of the keys, which was enough to reverse engineer the entire CSS system and disable the protection mechanism on all players The successor format to CSS is called Content Protection for Prerecorded Media (CPPM) and includes a number of improvements over CSS that added robustness and reliability For instance, CPPM does not use Title and Disc Keys anymore, replacing them with identifiers that are stored in the disc lead-in area This area does not exist on recordable media, making it impossible to create a duplicate copy of the disc, even if it could be decoded This method was first used for protecting DVD-Audio discs Yet, Hollywood was trying to find a content protection system strong enough for their valuable high-definition content Eight companies joined forces IBM, Intel, Microsoft, Matsushita, Sony, Toshiba, Walt Disney, and Warner Bros. struct s { char ch; int i; float f; } s_var; 268 268 279 292 294 300 306 324 326 327 remove password from pdf using c# How To Set And Remove PDF Document Security In C# - C# Corner

Antennas are an important consideration in optimizing wireless system performance, especially in a multipoint, sectorized environment, where one type may act as a sectorized unidirectional antenna, with a different frequency or polarization allotted for each adjacent sector. The following are some considerations in such multipoint applications: Horizontal beamwidth should be chosen to reduce overlap into adjacent sectors in order to increase BER performance. Front-to-back ratio and sidelobe suppression must be maximized to reduce cochannel interference, and thus improve the BER (antennas are available with a front-to-back ratio of up to 40 dB, but this figure can be degraded by 10 dB or more by multipath effects). VSWR, if at or below 2:1, will not normally be a large concern, since the resulting system loss will be only 0.5 dB or less. open password protected pdf using c# Create Password Protected ( Secured ) PDF using iTextSharp in ...
