The Digital TV Rating Survey System Based On DSP

TV ratings are in-depth analysis of the scientific basis for the television market, the program is to assess the main targets is the media planning and assessment, improve the effectiveness of advertising a powerful tool. Based on the analysis of traditional TV ratings based on deficiencies and shortcomings, is committed to digital TV ratings survey development, the development of a DSP-based digital TV ratings survey system.(1) by analyzing the digital TV ratings research and development trend, pointing out that the traditional TV ratings survey functionality and accuracy of the data do not delay, elaborated on the DSP-based digital TV ratings survey system in the digital TV ratings To investigate the application of advantage. On the basis of a study of DSP systems transform spectrum of technology-based-Filter, FFT and computing spectrum comparison.(2) According to the project's functional requirements, a DSP-based digital TV ratings system to investigate the overall program. DSP system design to achieve a system of modular, single-chip modules, liquid crystal display module, DS1302 timing circuit, and other hardware modules. Elaborate system of modular components of the circuit theory and methods to achieve, given the entire circuit system schematic.(3) described the software design ideas, combined with hardware, system design to achieve the bottom of the procedures discussed in detail the DSP system of communication procedures, single-chip LCD control procedures for liquid crystal display and control of single-chip DS1302 timing procedures, and to Out of the system software design process and the realization of the code.(4) the use of e-Wei Ming DSP system development platform for the experimental combination of DSP software development CCS, to verify the DSP system and the single-chip communication systems. Wei satisfied the use of electronic ME300B single-chip platform for the development of experimental single-chip combination of software development KeilC, single-chip system to verify the liquid crystal display and features a time.The test results show that the system designed to achieve a single-chip DSP systems and communications systems, single-chip liquid crystal display systems and hardware functions of time and at the same time give full consideration to the design of the system to expand, upgrade potential, Can be easily carried out on the basis of its further development.
