How is the data source and technical support of the comprehensive evaluation system of network-wide, sample-wide, big data and cloud computing achieved?

In the past, monitoring user viewing information provided broadcast time and program introduction information of current and future TV programs through Electronic program guide (EPG), which was widely used in smart TVs and Internet set-top boxes. TV users searched channels or program names and column names according to their personal interests, and quickly switched to their favorite channels to watch live broadcast or playback. However, this traditional EPG faces the problems of channel limitation and poor data recognition accuracy.

Tianmai Juyuan has accumulated in TV big data for many years, including more than 5 channels in China, and has carried out 24-hour automatic monitoring and manual inspection on EPG and advertisements of more than 12 channels such as CCTV channel, satellite TV channel and some city channels, reaching over 99% accuracy, and can provide reliable post-broadcast information within 3 minutes, including TV series, movies, cartoons, variety shows, songs and sports. The broadcast data of TV programs, such as which channel, which programs were broadcast at what time, and which advertisements were placed, can obtain accurate information through Tianmai Juyuan electronic EPG. The electronic EPG provided by Tianmai Juyuan Big Data is the basic data source of the comprehensive evaluation big data system of the State Administration of Radio, Film and Television. It is not difficult to see its important influence from the following five advantages:

★ Many samples, wide coverage, and super-large information source. At the beginning of the system, the viewing data of 4 million cable TV and IPTV sample users were collected.

★ Big data, cloud computing, real-time processing and accurate home. Big data, cloud computing, real-time processing and accurate home-to-home, can not only reflect the viewing situation of popular programs and prime time, but also accurately capture the viewing characteristics of minority programs and marginal time.

★ Anti-manipulation, anti-pollution, and solve the problem of viewing fraud. Zero viewing "will no longer exist; Data collection, cleaning, analysis, presentation and other links are seamlessly connected, and the whole process is automated and closed, effectively preventing human manipulation.

★ Multidimensional and omni-directional, and comprehensive evaluation leads development. The system can provide objective and true viewing statistics, and make multi-dimensional modeling and analysis of programs.

★ All-media, open and new orientation for the future. The system actively adapts to the development trend of technology and communication, and will comprehensively cover different communication channels such as cable TV, direct broadcast satellite, IPTV, Internet TV and network audio-visual field.
