We know that since IPTV is a service built on the basis of broadband network users, before 2003, narrowband users occupied the mainstream Chinese market, and IPTV had no soil to survive.
After 2003, after large-scale broadband upgrades and hard work on broadband users by China Netcom, Telecom and other operators, the scale has expanded rapidly. At present, China's broadband users have exceeded 10 million in scale, and they are initially equipped with high-speed Internet access to users. Provide users and technical basis for IPTV services. Beginning in the second half of 2004, the IPTV business using computers as the receiving terminal gradually surfaced. First, Beijing Telecom officially marked the price of network TV in September of the same year-30 yuan / month, and then Hangzhou Netcom announced the opening of IPTV services. Initially provide 9 TV channel program services. At the 2004 China International Communication Equipment Technology Exhibition held in Beijing from October 26th to the 30th of the same year, China Telecom stated that "new horizon" IPTV will be the focus of development that China Telecom is paying attention to, and China Netcom has also shown With great enthusiasm, it is reported that the technical solution is currently being tested and demonstrated and will be launched soon.
The mainstream media formats on the market today include three major series: MPEG1 / 2/4 series, Real series, and Microsoft series. Among them, MPEG 4 and MPEG 2 have great development potential, and H.264 is most likely to become the mainstream IPTV format standard in the future. "Dingdian Tianyuan" IPTV operation solution uses a completely independent research and development of a unified video pump, supports all media formats including MPEG 1, MPEG 2, MPEG 4, H.264, WMV, RM, RMVB, etc., while supporting PC , Set-top boxes, mobile phones and other terminal equipment. In terms of billing management and program distribution, a large number of special developments have been made in response to the operating characteristics of IPTV services. In addition to adapting to the adjustment of flexible operating strategies and methods, smooth upgrades and expansions can be made.
In order to make it more widely used in the market, Dingdian teamed up with Intel in the IPTV solution to take the lead in supporting high-performance Itanium 2 servers and EMT64 servers in China. It solves the problem of improving the concurrent on-demand performance of IPTV by more than 300%. Based on 64-bit Intel high-performance servers, Dingdian Tianyuan can make full use of its good internal I / O, greatly improve read and write performance, and effectively improve concurrent on-demand performance. At the same time, based on Itanium 2 server and EMT64 server, Dingdian Tianyuan IPTV service process can access more than 4GB of memory space, which will make Dingdian Tianyuan's memory-based program intelligent buffer storage function be used to the maximum. According to the theoretical analysis of users' access to media content and the analysis of actual on-demand records, a small number of popular programs can be found to meet the needs of most users. For example, through their analysis of on-demand data from Weihai Communications in Shandong, the most popular The on-demand volume of 10 programs accounts for 10% to 25% of all on-demand, and the top 100 movies account for about 40% to 50% of all on-demand volume.
For this reason, if memory buffer technology is used to read popular content into memory, it can effectively reduce the amount of data read from the disk array, thereby achieving the goal of improving concurrent on-demand performance. However, the collection of popular programs is constantly changing, therefore, intelligent cache scheduling of popular programs must be implemented. Intelligent memory buffer technology can keep popular program content in memory, which can effectively reduce the amount of data read from the disk array. Dingdian adopts a hybrid algorithm based on Interval and combined with LRU, which can automatically allocate the content of program blocks in memory according to the popularity of the program blocks on demand, effectively improving the hit rate of access. In the actual environment, when 16G RAM is configured as the memory cache, the program bandwidth is 384Kbps, and the average concurrent stream is about 2000, the use of intelligent memory caching technology can reduce the read of disk I / O by 30-40%. This means that the concurrent performance of Dingdian Tianyuan IPTV system will also be improved by about 30-40%.
Since its establishment in 1997, Century Ding Dian has been focusing on the field of streaming media. The video on demand system in its "Ding Dian Tian Yuan" series occupies more than 30% of the domestic market share, ranking first. The video conference system has firmly grasped the telecommunications, military, and education markets. The "Dingdian Tianyuan Broadband Multimedia Information Platform 4.0" released in 2003 was widely praised by new and old telecom-level users.
With the rapid development of IP networks and the continuous improvement of access bandwidth, it has become possible to transmit high-definition programs in real time, and for most users who are not proficient in computers, the set-top box + TV playback combination is more attractive force. In 2004, when IPTV first appeared, Century DingDian relied on the long-term experience of contacting the market and users, and was keenly aware of this market prospect, and strengthened research and development. They regard "providing a complete IPTV business operation solution for carrier-grade operators" as a key point for future business development. In terms of technology, they have already mastered the core technology of streaming media and the underlying technology of STB set-top box application development. However, in the past, its set-top box products were mainly targeted at users such as governments, enterprises, and the military; from a market perspective, Dingdian has always regarded the support of telecom operators as its main business and has many years of experience in telecom customer service. Therefore, it should be a matter of course for them to make IPTV solutions.
The prospects for IPTV are very promising, although the country has just started. It is reported that PCCW in Hong Kong has developed 400,000 users in just two years, becoming the region with the largest number of IPTV users in the world. According to the market research company MRG report, the global IPTV users will grow from 2 million to 28 million by 2008.
