Alphanumeric messages are encoded in POCSAG format and send to the serial port of a computer. The modem connects to the serial port of a computer and sends the message on the air through a transmitter.
This zip contains a simple paper of SPIHT generated streams run length encoded ... later i ll be posting the MATLAB source code also and also SPIHT with Arithmetic coding
simulating a convolutional encoder
allows the user to input a source code to be encoded and also input the values of the generator polynomials. It outputs the encoded data bits, where 1/n is the code rate
·詳細說明：JPEG2000的C++實現,可以參考它的程序結構,并可以測試編碼的效率-jpeg2000 c realization, may refer to its procedure structure, and may test the encoded efficiency 文件列表: JPEG2000的一個完整的C++實現 ....................
·詳細說明：MP3編碼庫，可直接將wav,aiff格式的音頻文件壓縮成碼流量為128Kbps的mp3文件-Mp3encode is a kind of mp3 encoded library which can compress wav,aiff files to mp3 files of 128kbps data flow.文件列表: mp3encoder-05-07-04 &nbs
In each step the LZSS algorithm sends either a character or a <position, length> pair. Among these, perhaps character "e" appears more frequently than "x", and a <position, length> pair of length 3 might be commoner than one of length 18, say. Thus, if we encode the more frequent in fewer bits and the less frequent in more bits, the total length of the encoded text will be diminished. This consideration suggests that we use Huffman or arithmetic coding, preferably of adaptive kind, along with LZSS.
This PNG Delphi version 1.56 documentation (this version is a major rewrite intended to replace the previous version, 1.2).
Improvements in this new version includes:
This new version allows the programmer to not use Delphi heavy units which will greatly reduce the size of the final executable.
Read more about this feature here.
Most, if not all, Portable Network Graphics features as CRC checking are now fully performed.
Error on broken images are now better handled using new exception classes.
The images may be saved using interlaced mode also.
Transparency information won t be discarted after the image is loaded any more.
Most of the images are decoded much faster now.
The images will be better encoded using fresh new algorithms.
IMPORTANT! Now transparency information is used to display images.
First of all, the Applet-phone is a SIP User-Agent
with audio and text messaging capabilities. But i s also embedded in
an applet where you can use it as usual if your firewall allow you to
use the UDP transport. If not, you can use TCP to carry your voice in a
voice messaging fashion. Your voice is recorded and encoded locally
then sent as a message, decoded and played back by your peer. Voice
messaging allow you to go through any firewall, so that you can
continue to chat and talk with your friends from an applet !
ATViewer is a component for Delphi/C++Builder, which allows to view files of various types. There is no edit possibility, just quick view - so it s useful to implement "View file" feature in your Delphi/C++Builder application.
The following view modes are implemented:
Text, Binary, Hex, Unicode: all files, of unlimited size. Plain file dump is shown. Used ATBinHex component: only visible part of file is loaded into memory. Modes are suitable for huge files and files of unknown type.
RTF/UTF-8: RTF and UTF-8 encoded texts. File is shown using RichEdit control.
Image: all general image formats: BMP JPG ICO GIF PNG... File is shown using ATImageBox component.
Multimedia: all file types supported by MS Windows Media Player: AVI MPEG WMV MP3... File is shown using WMP ActiveX control.
Internet: all file types supported by MS Internet Explorer: HTML XML DOC XLS... File is shown using MSIE ActiveX control.
Plugins: all files supported by Total Commander Lister plugins.
