TEM, multibyte character system). With this MBCS concept, we can express more characters, such as we have bits in 2 ASCII characters, and in theory there are 2 16 times 65,536 characters. But how are these encodings assigned to characters? For example, word-of-mouth "mouth" of the Unicode code is 21475, who decided? Character set, which is the charset that just introduced. ASCII is the most basic character

bit 8 (value 0x0100) Discrete 9 will be bit 7 (value 0x0080) Discrete 10 will be bit 6 (value 0x0040) Discrete 11 will be bit 5 (value 0x0020) Discrete 12 will be bit 4 (value 0x0010) Discrete 13 will be bit 3 (value 0x0008) Discrete 14 will be bit 2 (value 0x0004) Discrete 15 will be bit 1 (value 0x0002) Discrete 16 will be bit 0 (value 0x0001) 　　 When more than 16 bits, such as a discrete input modulus of 32 points, the discrete 1 to 16 will be i

1. Why is fflush (stdin) incorrect? First, check the following program: # Include Int main (void) { Int I; For (;;){ Fputs ("Please input an integer:", stdout ); Scanf ("% d", I ); Printf ("% d/N", I ); } Return 0; } This program will first prompt the user to enter an integer, and then wait for the user to input. If the user inputs an integer, the program will output the integer just entered and prompt the user to enter an integer again, then wait for user input. However, once the user do

MPEG-4 Part 2,MPEG-4 visual(Formally ISO/IEC 14496-2[1]) is a video compression technology developed by MPEG. it belongs to the MPEG-4 ISO/IEC standards. it is a discrete cosine transform compression standard, similar to previous standards such as MPEG-1 and MPEG-2. several

5. MPEG audio tags MPEG audio tags can be divided into two types: ID3v1, which has a file tail and a length of 128 bytes, and ID3v2, which is an extension of ID3v1 and has a file header with an indefinite length. 1. ID3v1 The ID3v1 label is used to describe the MPEG audio file. Including artist, title, album, publishing age, and genre. In addition, there is additional comment space. It is located at the end of the audio file, which is fixed to 128 bytes. You can read the last 128 bytes of the fi

If the user inputs an integer, the program will output the entered integer, and prompt the user to enter an integer again, and then wait for the user to enter. However, once the user does not

it were not for such a complicated project, the video files were much larger than we thought. Let's give an example:According to the CCIR 601 video signal acquisition standard, a standard PAL TV signal is converted into a digital signal, according to the common non-professional-grade sampling standard 4:2:0 (you want to support higher also not ah, civil-grade equipment do not get higher sampling rate), The resulting digital file for the video content

-byte character system, multi-Byte Character System ).With the concept of MBCS, we can represent more characters. For example, if we use 2 ASCII characters, we can use 16 bits. Theoretically, we can use 2 to the power of 16 to 65536 characters. But how can these encodings be assigned to characters? For example, the Unicode code of koubei's "Port" is 21475. who decides?

Resource allocation diagram, which is the process Resource Graph　　Simplification: The first step: see how many resources the system has left unallocated, and then see which processes are not blocked ("No blocking" that is, the system has enough free resources allocated to it) Step Two: Remove all the edges of the non-blocking process, form an isolated point, and then recycle the resources that the system allocates to the process Step three: See what the rest of the process does

HDTV Overview (2) I. rec.709 HDTV color EncodingRec.709 defines the YCbCr color encoding. Unfortunately, unlike sdtv's range factor definition, YCbCr encoding is divided into two types. One is used for small image (sdtv) encoding, and the other is used for large image (HDTV) encoding. Ii. Video Compression Direct storage or transmission of YCbCr digital videos requires a large amount of data throughput-about 20 mb per second for sdtv and abou
