Brief introduction to the success case of LETV P2P Streaming Application Platform
LETV Mobile Media Group was founded in 2004. Currently, the company has provided all-round streaming solutions and content production for China Mobile, which is based on 2.5G network platform, and China Unicom, which is base on 2.75G network platform. So far, the company has launched audio/video columns involving 30 channels and 12 categories on China Unicom's <MyUni>, including VOD and downloads of TV live broadcasting, movie and TV, music, sports and comprehensive programs, etc. Meanwhile, LETV Mobile Media has launched local streaming platform in Guangdong province and Jiangsu province by cooperating with the local Unicom companies. LETV Mobile Media, currently, is also the largest partner of China Unicom in wireless streaming.
LETV Mobile Media owns three brands which are “LETV Unlimited” , offering mobile audio/video and telecom value-added services, “LETV web” ( www.letv.com ), providing Internet audio/video services and “LETV(streaming) advertising Co.,Ltd.” , providing video advertising service based on Internet and mobile networks. It is a video portal website based on China Telecom and China Netcom's broadband network platforms. LETV is also the domestically largest professional video portal website which includes channels such as Movie Show, TV Show, Cartoon Show and Health Lives, etc. Currently, it has more than 2000 movies available for users to watch online and download. It's predicted that in 2006, LETV will own more than 15,000 movies, including some classic movies. LETV also created a brand new operational mode that TV Play Series are played first on web before on TV station. LETV successfully played series like < Happiness As Flowers>, <Bloom of Youth> as well as Hai Yan's new series < River Flows Lik e Blood>, <Five-Star Hotel> . Currently, LETV is incubating the brand new concept “Online Video Museum", ambitious to offer more comprehensive and colorful video programs for audiences.
To better serve LETV's users and conquer the top position in the online movie and entertaining service field, in September of 2005, LETV Mobile Media Group made the decision to purchase a sophisticated streaming operation platform to improve Quality of Service (QoS). After careful evaluations by the expert team and through demonstrations in all aspects, ForceTech defeated other tens of domestically well-known vendors and won the contract for delivering the ForceP2P streaming unified broadband operation platform for LETV. Most members from the expert team believed that the legacy streaming operation platform requires high bandwidth occupancy and demanding server configuration, making it impossible to implement VOD and live broadcasting in a large scale. For this reason, they knocked out several well-known companies in the first round of competition. In the second round, ForceTech and other vendors performed massive stress tests. LETV group randomly employed nearly ten thousand of students and website members to take part in the tests. After technical demonstrations and careful comparison of the test results, it was concluded that other vendors' P2P streaming operation platforms were distinctly inferior to ForceP2P streaming unified broadband operation platform in effects of live broadcasting. ForceP2P streaming unified broadband operation platform differentiates not only in its clear and smooth video effects but also in its ease to manage and accuracy of billing, thus wining the unanimously high appraisal of the Expert Review Team's.
LETV's key technical requirements in the bidding procedure are described as follows:
·Support multi-path and multi-channel video live broadcasting;
·Support 7*24 timed recording, automatic or manual collection and timed live broadcasting;
·Programs on each channel shall meet the needs of over 5000 broadband users (at the rate of 500K) to use the online audio/video live broadcasting;
·Secure and reliable, with a powerful emergency treatment mechanism;
·Support both user WEB certification and live broadcasting programs certification;
·High scalability and compatibility, supporting smooth and easy system upgrading and scale-up;
·Seamless integration with existing application platforms in aspects of user certification, billing, statistical analysis, server clustering, data storage and so forth.
After one half month's implementation, currently, the system has been put into operation with ten thousand concurrent online users and visits every day.
