proficiency. For example, in the communications industry, IPTV industry, mobile phone industry, you understand the needs of the industry. Therefore, when the leader of the people, more is to do the application. 3. Do drive, in fact I do not want to call "do the drive", but want to call "do the bottom system", do this is to kill the various industries. I worked for a few years, I did mobile phone, IPTV, con
Telecom Wireless Optical Cat Setup method
This article takes ZTE F460onu as an example, introduces the setting method, the open business includes, voice (telephone), broadband, IPTV.
First of all, do a physical connection, here do not introduce, not clear to ask me alone.
After connecting the 192.168.1.1 into the Light Cat settings page, user name: telecomadmin Password: ne7ja%5m

voice means to achieve High-quality Network Conference broadcast. Such applications will be many, even more exciting is that we can open up their own network television/radio, as a private media for the network broadcast. Field Three: Provide IPTV service for school campus network. eg: Beijing University IPTV Group broadcast service 3G era is coming, I hope this streaming media technology for 3G video s
At present, in the IP network, the operator's network to provide more services for the purpose, no longer in the form of xDSL to provide users, but directly provide a unified width interface, in some broadband community this form is particularly common.
At present, in the broadband community to apply the most in addition to Internet services, more is to provide IPTV applications. In the promotion of IPTV, f
The development of family business is in the embryonic stage, has not yet formed the unified norm and the business model, the operator should seize the opportunity, from simply provides the Internet access to the broadband-based integrated service provider transformation, by the home gateway, the IPTV set-top box, the integrated Broadband Intelligent terminal, the WiFi handset, Video telephony and other broadband network terminal equipment to form a h
There was a sudden interruption of broadband at home yesterday afternoon.
Checked with Telnet method, found that the light cat (Huawei HG8240) telecomadmin password was changed.
Retrieve the password, into the light cat, found that the original cracked after the bridge mode has been changed by mode. [Wrath]! The hateful telecommunications has remotely modified my device. It seems that the last lazy left a hangover. All right, this time we have to kill this TR069 management agreement.

Iconv-String Conversion Based on the required character encodingString iconv (string $ in_charset, string $ out_charset, string $ str)
Encodes str from in_charset to out_charset.
The conversion method is simple. You can simply use the iconv method.

String iconv (string $ in_charset, string $ out_charset, string $ str)When using this function for string encoding conversion, note that if UTF-8 is converted to gb2312, the string may be truncated.You can solve this problem by using the following methods:Copy codeThe Code is as follows:// Author: zhxia$ Str = iconv ('utf-8', "gb2312 // Transcoder", file_get_contents ($ filepath ));That is, add the red part in the second parameter to indicate that if
this method, so find out if there are any functions in PHP that can meet my needs.
At this time, I thought of the iconv () function used to process file names in windows. Its function prototype is as follows:
string iconv ( string $in_charset , string $out_charset , string $str )Performs a character set conversion on the string str from in_charset to out_charset.
We often use:
$out_charset='utf-8';$fileName=iconv($fileName,$out_charset,'gbk');
To process the file name, change the file name
Introduction to Audio/Video Encoding
1. Tools used:
Mplayer (command line-based player)
Mencoder (command line-based Transcoder)
Firefox (graphical browser)
2. Any video can be played in three steps: Unpacking-> decoding-> Rendering, Corresponding to the player separator (demuxer)-> Decoder (decode)-> Renderer.
(1) unpackingThat is, the process in which the player calls the separator to correctly extract the video track and audio track in the package
C language is more suitable for operating hardware and is more efficient in some file processing operations, so similar operations generally use JNI to call C code for operations: such as audio, video and image processing:
For example, in audio format Transcoder, similar to photo's rendering of image effects and other applications, a large number of JNI applications are required.
Here we will review the content of the C language operation file:
