1. It's better not to touch bitcoin, because the risk of virtual currency explosion is too great, and the most important thing is to keep the principal

2. I don't think much about the brand

3. 1、 General download method: 1. Http / ftp protocol: download directly with IE or Internet Express. 2. MMS protocol: Download with "video conveyor" (download address: Tianji download channel). 3. RTSP protocol: Download with "video tape". It should be noted that some RTSP movies may need to be downloaded by modifying the "RTSP" in the download link to "HTTP" in the video conveyor. At present, the popular movie format extensions are,. DAT,. Avi,. RM,. RMVB,. ASF and. Mov Dat file is the VCD file in our home. If you want to the movie from VCD disc to the computer, just out. Dat file. AVI file is the most basic and original movie file format in windows. Dat file is compressed by MPEG technology. AVI file stores movie digitally, So the file volume is very large RM file should be familiar to everyone. It is a kind of online streaming media file. It is small in size and is made by alnetworks. Its playing software is RealPlayer. ASF and mov are also streaming media files, which are made by microsft company and QuickTime company respectively. The playing software is Windows media player and QuickTime. Some people can ask, what is streaming media? Streaming media is: when the server receives the client's connection request (such as watching a movie online), the server decomposes these video files into many packets while transmitting them, and then transmits these packets to the client, and the client reorganizes these packets and displays them on the screen in real time, Make these signals flow continuously from the sender to the receiver, procing a continuous signal flow. Streaming media technology generally has three aspects: encoder (encoding technology), player (playback support) and streaming server. Rmvb file is a new file format rising on the Internet recently. It is upgraded and extended from the RM movie format of streaming media. VBR is the abbreviation of variable bit rate. When we play the common RM format movies in the past, we can see the word 225kbps in the lower left corner of the player, which is the bit rate. The requirement of compressed sampling rate is different between the still picture and the moving picture. If the bit rate is always fixed, the quality of the movie will be wasted. Rmvb breaks the way of average compression sampling in the original RM format. On the basis of ensuring the average compression ratio, it sets the maximum sampling rate which is usually twice the average sampling rate. High bit rate is used for complex dynamic pictures (song and dance, flying car, war, etc.), while in static pictures, it is flexibly converted to low sampling rate, which makes rational use of bit rate resources, so that RMVB can maximally compress the size of the movie at the expense of a small amount of movie quality that you can't detect, and finally has a nearly perfect audio-visual effect close to DVD quality, Rmvb player is RealOne player 2.0. 2、 At present, there are many ways to download movies, such as BT, thunderbolt, donkey, network download, reallink, etc. Because we are "helping each other", we will not rece the download speed with the increase of the number of users. BT features "the more people download, the faster the download speed.". If you want to download movies through BT, you generally need three basic steps: 1. Install BT download client. At present, there are many BT download client software, the most basic of which are BitTorrent, shareaza, BitComet, etc. Search the Internet, download and install. 2. Search for BT resources and open websites containing BT resources (such as: http://www.bitower.com , there are not only rich BT resources, but also detailed BT learning tutorials. You can go up and have a look.) click the attachment of ". Torrent" in it. When the browser asks "open" or "save", select "save" and save the ". Torrent" file to your computer. 3. Download. Find the saved ". Torrent" file and double-click it. The system will automatically open it with BT software. Select the saved directory and click OK to download. Of course, BT download still has a lot of knowledge, this is not detailed, interested friends can search online download skills or reply to me. Thunderbolt: thunderbolt is a new download tool which combines the multi thread of FlashGet and the peer-to-peer advantage of BT. when using it to download, it gets rid of the limitation that traditional P2P software can only deliver peer-to-peer content on the client, that is, when there is no other (seed) users to share resources, it can also download popular games, movies, music and other media with network image, Realize multi server overspeed download. Specific use, you can go to http://www.xunlei.com/ have a look. EDonkey: eDonkey is commonly known as ED, electric donkey or donkey. Like BT download, they are popular file sharing download tools, and the software is easy to configure and use. Specific operation, we search on the Internet. Under the network bar: under the network bar is actually realized through BT technology, we can regard it as the secondary development of BT, you can go to the network down a network bar software, install it, use it very simple, I will not elaborate here. reallink:reallink The interface is similar to QQ, very simple to use, it can also achieve some basic functions of QQ, such as chat, file transfer, etc http://www.reallink.cn/ Download the latest version of reallink from the website, and apply for a reallink number through the wizard after installation. The process is similar to QQ. Login software, through the file search button you can search the movie you want, very convenient. Of course, reallink file download implements the gold dollar system, and there is no virtual currency of reallink. When downloading a movie, it is actually through the gold dollar to buy a movie from the user who provides the movie download. The ways to get the gold dollar are as follows: 1. Automatically increase the gold dollar online, and when the user's gold dollar is less than 100 points, increase 20 points per hour. 2. The proportion of direct payment and post office remittance is 500-1000 gold yuan / 2 yuan. 3. For selling movies, you can also provide them for others to download and set the price of gold yuan. When someone downloads the movies you share, the number of gold yuan will rise accordingly. If you are an ecation network user (if you surf the Internet in school, you are usually on the ecation network). Internet cafes, home we call the public network), using these methods to download movies may be very slow or simply not work. Here, I recommend a website to download movies on the ecation website: e.pku.e.cn. The movies searched by it are generally in the ecation website, so the speed is relatively fast.
