1, that is, point-to-point broadcasting, is a long-standing dream of people. Today, it has been realized through internet cafes, which is essentially different from renting several vcd movies by families. The film and television server in the Internet cafe can store a large number of film and television dramas to watch at any time, and it is also very convenient to change films, thus realizing real on-demand broadcasting.
2, can master the latest movies (of course, this is all because of piracy), and it is much cheaper than going to the cinema (the new movies in the cinema are generally about 10 yuan).
3, to meet the requirements of people who don't like being dragged by TV dramas, I finished watching dozens of episodes in three or four days, which was enjoyable.
You can kill two birds with one stone by chatting while watching movies.
5. Decompose the pressure of narrow band. The more movies you watch, the lower the Internet utilization rate of Internet cafes, so the less pressure on bandwidth, the faster the network speed, which is especially important for Internet cafes without broadband.
6, this is that there are many other advantages! .
The requirements of the Internet cafe film and television system should be:
Put a movie project in a prominent position on the computer (for example, set a shortcut of "movie appreciation" on the desktop), so that guests can see the catalogue of all movies after opening it, and open the movie file after selecting it, and the system will automatically bring up the playback system and start playing.
Of course, some people make this system web-based, and the effect is like online video on demand, but I don't agree with it, because the system made in this way is very professional and difficult to maintain. Every time you add a new movie, you have to make changes on the web page. The web page itself and links are prone to errors, which will affect the actual effect. The simplest and most practical method is to save the movie in the computer and make it * * *, and all clients can watch it through the online neighbors.
The following are the relevant settings of the movie service system in Internet cafes (as simple as that)
0. First of all, your network has been set up, and you can exchange visits through online neighbors, which is the foundation (if your customers can access the Internet, this is not a problem! )
1. Choose a computer (or several computers, each one is more troublesome) as a video server, copy your movies to the hard disk, and set all the movie files as * * * sharing (usually * * * sharing folders, each folder has a certain number of movies);
2. Install the playing software on the client, and establish the fast access mode of movie files on the video server;
Nothing, it's as simple as that. (Oh, isn't it over? Don't tell me your sound card isn't installed yet! )
Of course, there are some knowledge that can make your video system perform best:
Select the appropriate playback software.
The following are several kinds of playback software I have used:
Windows Media Player+Divx (mpeg codec) is mainly used to play movies in mpeg format. Its advantages are fast startup and few system resources, but its disadvantages are that it does not support many formats (fatal).
Most Internet cafes are using realplayer, because it is a special playback software in rm format, with simple interface and easy production. The old version of real doesn't support movies in other formats, but the new version supports many formats, including mpeg format, because it adds multiple plug-ins. However, I found that some versions of real can't fast forward when playing mpeg, and there will be a false crash when dragging the scroll bar, which can only be solved by ending the task with three keys.
Kingplayer iii supports the most complete formats (including music files), and the installation does not take up much space (less than 40 megabytes for complete installation), and takes up less system resources.
Oriental Cinema supports many formats, especially the stereoscopic version, which allows you to watch stereoscopic movies. The effect is really cool, but it also has many disadvantages, such as a large installation space (80 megabytes for a complete installation) and a large consumption of system resources.
In addition, Super Jieba 2003 is said to be good. I have never used it, and I dare not jump to conclusions (but I don't care if there is no qualitative change compared with 2000). Interested friends can try it and compare it with other software.
According to my experience, I first recommend Kim Young-Sam as the playing software of Internet cafes (I solemnly declare that I never charge Jinshan Company a penny for advertising! )
Attachment: Disambiguation of two popular compressed image formats, mpeg (corresponding to file extension avi) is actually an audio and video compression technology, which is a lossy compression by recording the information of the original audio and video files, replacing the encoding with some algorithm, and decoding by mpeg codec when playing. Rm is our most common compression format, and another algorithm it uses has a larger compression ratio (the file size can be reduced to half that of mpeg), so the distortion is greater and the effect is not as good as that of mpeg format.
Matters needing attention
1, the video server should not be the same as the network server. If your Internet cafe is large enough, it is recommended to use a dedicated video server (if it is not open to the public, the configuration can be very low, and the main frequency can be 300; 64m memory is 128m, which is the best. Waste too much memory. Motherboards that support large hard disks can, but they should be stable; Of course, the hard disk should be large, and 5400 rpm is enough; If you want to open your business to the outside world, you need a slightly higher configuration. Celeron II processor is recommended. Of course, if your Internet cafe is small, there is no need to set up a special video server.
2. Try to install movies in rm format, which has the advantages of small hard disk space, fast transmission speed and more terminals supported by a movie server. The disadvantage is that it is not as good as mpg4 and vcd, but as long as the cd is not too bad, it generally has no effect.
Be sure to appreciate and create shortcuts for all your movies, so that you can see all the movies on any terminal. If your movie is stored in several computers, you should first create a folder, put the shortcut of the movie on other computers, and then copy this folder to the desktop of each terminal, put beautiful icons on it, and take a file name similar to "movie appreciation". This method is also applicable to the use of various songs, and a "music appreciation" can be established in a similar way.
4, network settings: choose fast login among Microsoft network customers, so that the network driver will not be detected during the startup process, and the startup speed will be accelerated;
When logging in, you can choose windows to log in, and there will be no login dialog box during the startup process, which can avoid the situation that you can't log in to the network because the login time is cancelled (in this case, the client can surf the Internet, but can't access the online neighbors).
5, the same film can be called by several computers at the same time, generally does not affect the effect, but try to avoid (hard disk loss). If there are too many people watching a movie at the same time, make several copies on the hard disk in advance (try to choose different partitions) for recall.
6. How many users can a movie server support to watch at the same time? Medium-sized Internet cafes (single video server, less than 50 clients, using 10m network, of course 100M network is better) A video server can support about 20 computers to play rm movies at the same time (mpeg or vcd will be less). In fact, it is impossible for all customers of Internet cafes to watch movies together (generally below 50%), so this figure can basically meet the needs of less than 50 Internet cafes.
Example of actual environment (my Internet cafe): Yi Tuo University, 36 computers, 10m network, single video server (c2-600, 128m, 2*40g/5400 rpm, open to the public); Store movies in different folders according to their types (such as Jackie Chan's Complete Works, 007 Complete Works, American blockbusters, New Year's films, so-and-so TV series, so-and-so cartoons, etc.). ), enjoy these folders, set shortcuts on video servers on various computers, and change the title of * * * to video appreciation; Four hubs (three 16 ports and one 8 port) are stacked together; When it is full, about 15 people usually watch movies at the same time, and at most 19 people watch movies at the same time (and listen to the music of the video server at the same time). Working normally, there has never been a broadcast storm.
Suggestion:
1, advertise more. Many people think that "Internet cafes are just surfing the Internet", but they are not. We can make this part of the movie bigger, make it an important part of our business, and expand the market of Internet cafes. The only way to achieve this goal is publicity.
2. If possible, you can install dual headphones in a spacious position on the computer (to meet those customers with poor economic conditions and special customers). Couples often come to my place for vacation, and the content is to watch movies together.
Pay attention to local cinemas and introduce the latest and best movies in time (as for the introduction method, please support originality if your economic conditions permit. Oh, I learned to say that, too Unfortunately, I haven't supported the movie yet! My kind of economic conditions are not allowed! )
An example of failure (please take a warning)
I have been to an Internet cafe. There are 40 computers with 20g hard disks, and many movies are loaded in each hard disk. But I can't see any movies on his computer. I have to go to my online neighbors to find out where there are movies and I don't know where there are. If I know which movies are in which machine, I have to ask my boss what movies he is watching. It's really troublesome. Advantages have also come into play, and a lot of hard disk resources are actually wasted.
Movie recommendation:
Having a suitable film is one of the keys to the success of film and television service. There are probably two kinds of movies:
A good movie (a movie with a large audience is not necessarily good): a hot pen that everyone likes to watch (to be honest, I also like to watch this kind of kid's toy! ), the feeling is deep rain (this series has brought me great benefits, although I never appreciate Aunt Qiong Yao's works, which are too sensational, and I know the ending at the beginning, but it allows her to design such a complicated process. I admire her old man's skill. Of course, because she helped me attract many customers, I am only grateful for her existence now. The effects of these two films in my office are described as "sensational"
New movies: the other is popular, which is being shown in the cinema, and it is best to show it in the cinema.
For example, some time ago, Cohabitation Close Friends, Pearl Harbor, Slimming Men and Women, shaolin soccer, My Brothers and Sisters and so on. My Pearl Harbor was released one month earlier than the cinema and received rave reviews. Many people even spent four yuan to read it and said it was cheap.
Difficult problems and related problems in film and television communication;
It's normal for internet cafes to have problems, but it's not normal if there is no problem. Of course, the film and television system is no exception, but its problems are generally easy to solve compared with the network problems.
Realplayer's channel problem, realplayer can't adjust the channel, which is the biggest bug of this software. Upgrade n times has not been solved. I have no idea what these software manufacturers are doing. Of course, we also have a way to deal with it, that is, calling the sound properties of the system to adjust the channel (a bit troublesome). The method is: bring up the sound properties (the fastest way is to double-click the small speaker icon in the taskbar) and adjust two items. If your menu is in Chinese, these two items are the main volume and sound wave, and if it is in English, it is the volume and sound wave. The sound channel is mainly controlled by the volume, and sound waves can optimize the sound properties. The actual comparison shows what these two items are all about. To add the most important point, your movie must be dual-channel to adjust. If the disc maker makes two channels together, it's no use tuning them again.
Intermittent problems occur during playback, and the sound or image is intermittent during projection. If it is a network factor, it may be a problem with the movie server, which is the case when computers watch movies on the local area network. This phenomenon will be obvious. At this time, we have to deal with the movie server. If it is only a single machine, please play again and restart at the latest.
The problem that audio and video images are different, and the problem that sound and image are inconsistent in the process of watching a movie is that the playback equipment and image equipment are not coordinated when the system is processing, which can usually be solved by closing the current playback task and reopening it.
The problem that can't be played is that no matter how you double-click it, you can't open the movie file. This is because the current system resources can't call out the player, and it needs to be restarted to solve it (don't forget to tell me if anyone has a simpler solution! )
For the problem of low volume, if there is nothing wrong with your sound card (some sound cards have low volume, which is difficult to solve from the software aspect, so you can only add active speakers to increase the volume), in addition to maximizing the earphone volume and the main volume in the sound attribute, it is also important to adjust the sound wave attribute. Often, improper sound wave setting will lead to low volume. Please adjust the "balance" left and right to find out the best effect.
Well, I've talked a lot and I'm really tired. I will be very happy if these words can bring some understanding to those colleagues who are in a confused state. If the film and television system you made really helped you improve your efficiency, I couldn't be happier. Of course, because everyone's specific environment is different, and in order to avoid the disconnection between theory and practice, I also try to proceed from reality in my writing, but some mistakes or incompatible results are inevitable. Welcome to correct me, and continue to discuss with me the technical and operational problems of video service in Internet cafes! I hope everyone gets his place!
Add two points
1, the configuration of the video server does not need to be too high. I have used three configurations: C400/64, C566/ 128 and P3 733/256, which have little effect on the viewing effect of the client.
2. One server supports clients of 10m network, and one server can support 20 terminals to play rm format. But if it is mpeg format, it can only support about 10, which means the playback effect is better. If the number of terminals exceeds this number, it can actually be supported, but the effect will be reduced (there will be occasional pauses or different audio and video).
Analysis on the Configuration and Construction of Movie Server in Internet Cafe
Supplement: Scholar Weng Source: Unknown Joining Date: August, 200313 Fujian Internet Cafe Alliance.
The arrival of the broadband era has brought people from simply browsing the web to sending and receiving emails to a brand-new multimedia era. However, the development of bandwidth can't keep up with the publicity and promotion of various media, which is an embarrassing topic for a long time.
Internet cafe customers want to watch movies, and the export bandwidth is crowded. This contradiction is difficult to overcome in most Internet cafes, so we have to set up our own video server.
Based on the principle that the flower must be spent and the province must be saved, the construction and configuration of video server are discussed.
The first is hardware. Video server hardware selection needs to pay attention to the following points:
1, no need for high-frequency CPU.
When providing services, the main feature of video server is continuous I/O* operation. CPU resources are not occupied. In my experience, an Internet cafe with 50 machines and a CPU of around PIII500 can be very competent.
2. High stability.
High stability is very important. Generally, the video server will run continuously for more than 10 days-1 month. If you turn off the computer when the guests are watching with relish, it will damage the image of your internet cafe. If you have a generous budget, you can consider choosing a server motherboard with 64-bit bandwidth, which is very beneficial to the continuous massive I/O*. However, this motherboard generally costs more than 2000 yuan. Considering the budget, this is a bit expensive. So generally speaking, you should consider those ordinary PC motherboards with good reputation or you are very confident in their stability. Don't chase the newly listed models. I recommend two motherboards, Mei Jie 6BA+IV 6BA+IV, AbitBH6. Both motherboards are old BX motherboards, and the price may be 600-700 yuan or lower. But their stability is impeccable.
3. Storage subsystem.
Storage subsystem is the key of video server.
In order to adapt to a large number of I/O* operations of the video server for a long time, it is absolutely not advisable for the system and video files to share a hard disk. You must use a separate disk or disk array to store video files. If you choose the server motherboard with SCSI interface when choosing the motherboard, then we can consider using SCSI hard disk. Of course the price is high. A 30G ordinary SCSI hard disk costs about 2700 yuan, so we choose IDE raid. For what RAID is, please refer to the relevant documents. Both highpointtech and promise provide us with suitable RAID products. Generally, products with market price above 400 yuan can adapt to this working environment well. Be careful not to buy some "soft" raid cards, which will have poor performance and consume a lot of system resources. RAID 100 in Iwill is a good choice. It is recommended to use the 5400 rpm model for hard disk, because the overall disk performance will be nearly n times that of a single hard disk after using RAID to build IDE array. It depends on the number of hard disks you have.
The 7200 rpm hard disk is too hot for a long time, and its performance is higher than that of the 5400 rpm hard disk. It is useless after being amplified by RAID, and its price is obviously higher than that of the 5400 rpm hard disk. That's why you don't use a 7200 rpm hard disk.
You need at least 2 hard disks to use IDE Raid. Adding a hard disk installation system will cost you the storage subsystem.
Raid card ￥480
Hard disk × 3 1600
If your budget is really tight, you can give up IDE RAID and just use a 7200 rpm hard disk to store video files. Note: It is strongly reminded not to put the system and video files on the same hard disk.
4. Network part
Don't use the cheap 8 139 network card. Intel 10/ 100M Pro+ is recommended. 250 yuan RMB is probably needed.
The video server should be connected to the backbone switch of the Internet cafe.
If you are still using the 10M network, upgrade your network first.
Software part.
1.* makes the system Win2000 server or advanced server version. If you can use Linux or FreeBSD to build a platform, then you don't need to continue reading this article. )
2.Web server IIS5.0
3. RealServer8.0+ and Windows Media Server of streaming media server RealSystem.
When installing Win2000, IIS is installed by default when installing W2k. You only need to select three components: Web services, public documents and server management. By default, the media server is not installed. Remember to choose it. Pay attention to install the system on the hard disk specially prepared for the system, and put the streaming media files on the hard disk or hard disk array specially prepared for the streaming media files. Build a directory named Media as the mount point of RealServer. You'd better not put anything else here.
RealServer can be downloaded in many places. It comes with a 10 user license. One input is required during installation. Finally, you need to set the user name and password of the management interface. After installation, two icons will be generated on the desktop. Run RealServer 8.0 Administrator.
Enter the configuration interface. At this time, you need to enter the user password, which was set by yourself when you first installed it.
Select configuration-> General settings->; Connection control, change the setting of the maximum number of client connections to the maximum number supported by the license. The maximum number of licensed clients is the maximum number of your licenses.
Configuration-> General settings->; Mount point, fill in the name of the virtual directory where you want to access the video stream in the box below the edit mount point. If it is a movie, then fill in /Movie/ If it is E:\Media, then fill in E:\Media. Then click the edit button. Click the Apply button again. The industry will pop up to tell you that the modification is successful and you need to restart RealServer. Restart it. Click Restart Server at the top for about 20 seconds, and the restart is complete. Now copy any rm format video file to e:\Media\,
Let's say it's 0 1.rm. Then suppose your IP address is192.168.1.165438. Start RealPlayer, select the open location in the file menu, and fill in RTSP:/192.65438.
If there is nothing unexpected, you will see that the RealPlayer display is buffering and will start playing in a few seconds. Now please go back to the configuration interface of RealServer, click Monitor, and you will see the operation of RealServer. Player Connections shows how many users are currently connected. File usage shows the number of different streaming files currently on demand. CPU utilization shows the CPU utilization of the actual server, memory utilization shows the memory utilization, and bandwidth utilization shows the bandwidth utilization.
At this point, the streaming media server of RealServer has been installed.
