| On July8,2010, the State Administration Of Radio Film And Television(SARFT) Science and Technology Division, to the relevant units issued by SARFT Science and Technology Division, decided to set up the next generation of radio and television in China on the establishment of the Working Group of the China Next Generation Broadcasting (NGB) Notice working Group, the implementation of the relevant NGB promote the implementation of the work; Google TV and Apple TV in full swing, SAMSUMG smart TV has been successfully launched.In this environment, the intelligent set-top box with the produce in China, so the smart set-top box has become a hot research and development of major set-top box manufacturers.In this article, the introduction of the smart set-top box is based on the SMP8671chip as the basic hardware platform, Android2.1as the basic software platform smart terminal.This article briefly describes the related concept of digital TV, the development status of the smart set-top box at home and abroad, the significance of research and development of the smart set-top box, and focus on the internship process of Zhejiang Chuangyi Technology Shanghai R&D center mainly involved in the completion of three tasks:1) Smart set-top box system the entire middle-tier code completion, code maintenance and debugging of all modules in the middle layer of the set-top box. Completion of the transplantation of a digital TV module on the Android system;2) Completion of the entire module of the smart set-top box network media player, including the bottom, the middle layer, the upper completion and maintenance of the code, and with the testers testing, module-related problems resolved, the client pages of online video production and online video server structures. To achieve a major breakthrough in digital TV set-top box industry from the browser to watch online video in the domestic firstly;3) Completed the Smart set-top box online upgrade module. Including packaged the underlying code, the middle layer, joint commissioning with the application and code maintenance, and with the testers testing, module-related problems resolved. Digital TV bigger files online upgrade tasks was firstly completed on the Android system in the domestic.I familiar with the entire system architecture and design of each module functions to achieve the relevant code, and submit the test to solve the problem after the test, a share of about11months, writing nearly10,000lines of C code. Research and development of the smart set-top box has just started, when I complete the development tasks, encountered about20several thorny issues, such as online video window size, scroll bar problem, key response to the problem, etc., through my own constantly thinking, research, network resources and references to find, and ultimately the successful completion of development tasks. Research results in this article, which has been used in Zhejiang CHUANGJIA smart set-top box. It’s not only a certain reference value for the study of China’s digital TV smart set-top box, but also for China’s next generation of radio and television network as soon as possible to come to make a certain contribution.In the thesis, as a key member, I participated in the removal of impulse noise method of digital image specific learning study at home and abroad several typical digital image impulsive noise removal methods, we analyzed the internal mechanism of the variational method in the removal of impulse noise of digital image, according to the variational method to remove noise internal mechanism, proposed a fast algorithm to remove the digital image impulse noise, it has been accepted at the2012IEEE International Conference on the Image Processing. I have written nearly2000lines of C language code to simulate several classic digital image impulse noise removal methods at home and abroad, the proposed algorithm not only to remove the good effect of impulse noise, and it is a fastest removal impulse noise method of the best effect at home and abroad now. |
