Video talk chamber software, technical standards

Conventional video chat software customization and group operating according to their need to multiplication unlimited categories, and set differ for different groups of functions and icons; custom group other administration, whether hitting, is it feasible to look dense wheat, etc.; video chat software to ensure ultra-low bandwidth, Telecom and China Netcom are not using H264 codec video card, low bandwidth, even now the retransmission buffer mechanism to assure severe parcel detriment, remains good achieve; audio codec using G.7221, 24k to assure that the same as the local non-destructive quality mp3; video chat software, a powerful extension of ; the skin through the xml control software, can accessible can be replaced at replacing xml; the database devise is reasonable, anybody website can fulfill with existing socket; software built-in feature open and slightly modified, is a complete carrier-class operating platform; video chat software super permanence can be a distributed set of linked multi-server, unattached server edition can too be efficacious to prevent DDOS bombards; ; stability ambition not be dripped; video chat software uses UNICODE multi-language coding; choose to install the language installation;
FMS Why is not suitable for video chat room FMS is short for Flash Media Server,Christian Louboutin Boots, Media Server in Chinese means FLASH, FLASH enterprise produced a flowing media server, for the client computers are installed in most of their clients FLASH, so in this amplified above the foundation of the video chat do not need to download the client software can be achieved online. However, there are several lacking FMS can not be applied to make free video chat industry.

All such expressions, awards, whether always on the service side, prefer than the software on the client so the client end of the show will result in also slow, the problem of long load times (WEB chat room also has this problem), so in mandate to solve this, the evolution company will establish a plug-in to the statement ah, ah presents pictures, or chat rooms and other content placed on the local interface, alternatively as mini as possible with pictures, so the chat room on the WEB in common was the rather crude.

FMS video transmission using the TCP transport, which is malignant not the chief cause for video chat.

video chat and other audio and video content transmitted file packets many, and when it needs a very solid, so in this adore, the general will use UDP for transport, simply contracting rapid UDP, TCP is very slow, but effortless to UDP packet loss and retransmission mechanisms of TCP with packet loss. Therefore, each TCP packet is sent to the server and then forwarded by the server to the client, it requires a long process, this process is certainly more than 2 seconds even longer, and that kept large values of data sent, TCP's mechanisms to handle with, real-time can not be vouched, and that FMS client ought have a buffer mechanism, that is sent over the data to the client behind the 1st in memory, and then re-stamp packages received Play, originally transmitted on the slow, the buffer and a few seconds here, so the use of FMS to see that there is not Mosaic code, the effect is very good, but by least 10 seconds tarry. And this delay in the chat room to interact very solemn problem.

1: Blue Sky chat room (network edition) 2:9158 (software version) 3: Sina show (software version + web version) Why do not video chat room software is suitable for P2P
P2P namely, it method PC TO PC,Christian Louboutin Slingbacks, simply, customer demand is hoped namely a way apt use the calculator as the displacement of computer , so that the server does not share resources, not accounting because bandwidth transportation between the client, so absent from hardware investment. Why do we mention that chat rooms P2P software is no appropriate for it?

P2P is computer to computer, then we are for a reason, if a room of 200 human online, and immediately Michael A user on the public, other people should see A 199 , then the manipulation agenda is P2P, A video of his transfer to the other one, that A needs to transmit data to the 199 199 individuals in China, A user's bandwidth, even very good, that is the 2M of ADSL,Christian Louboutin D'Orsays, and some customers 512K or use of ADSL, 10M or 100M private users preferential use is very small. Let's make a enumeration, if the user A video or audio of each occupation is the amount of 50K,Christian Louboutin Pumps, then he can transfer the line 2M how many users it? The highest limit is 40, not to speak of ADSL is the methodology 2M 2M, the substantial applying process is unattainable. That means the other 150 users will be incapable to win data from the A, the client has talked to some, why not here from the received data to receive it? Video chat software is a very lofty real-time software requirements, such as BT, as the data transfer mode, in which the application is very difficult, and this point, the domestic PPLIVE very good software to do so, but such programs video chat applications, the effect is not. Therefore, the transmission mode suitable for P2P small chat room, as if the country through E, and other software, there are 10 type, 15 type of chat room is accustomed by P2P traffic.

customers will say, that UC is how to do it? UC is not remove whether the use of P2P, chat room as a large operator is cared, he is impossible not to consider the price of the hardware, he could do with a part of P2P, and then when the load exceeds the server while the consumer uses transit, That can be achieved, the cost of this development can be colossal.

there is a reason, P2P has been through a tough, you may have seen on the Internet through a lot of that P2P, but in fact, China has hundreds of routers even more brands,Christian Louboutin Discount, and their different standards, but also to penetrate all of the work of a very difficult to achieve, we can still recollect the QQ video chat connection barrier tips when joining unreasonable, is transit through the server, of course, we can develop When connecting the barrier P2P convey through the server to solve this problem, but he cost the same to the server.

In this context, it was intended some solutions, for example, we are seeing at public and wheat, with the broadcast. Private wheat,Christian Louboutin Shoes, wheat hidden people favor to see less, you can use P2P to transfer, yeah, this is a very good solution, but throughout the all chat room market, the largest video chat rooms, no more than 2,000 online people merely, in order to develop such a big investment in software development costs, the customer can have a few real applications of it?
