This paper stresses the importance of IP Industrialization to the success of China’s innovation-driven strategy based on the current Chinese situation, which is right underway. With many cutting-edge problems arisen from the implementation of China’s intellectual property (IP) rights, this paper tries to solve the IP finance difficulties by IP pledge financing and IP securitization; to sort out the relationship between IP implementation and the antitrust enforcement; and to actively participate in International IP rule-making. We also suggest that judicial protection is considered with high priority in Chinese IP protection and development. In addition, it is needed to perfect the in-employment invention system in order to balance the interests of different stakeholders, as well as to use economics methods in assessing IP value. This paper urges the Chinese government to respect the law of market and create a favorable macro-economic environment for the Chinese innovation-driven strategy.

It is absolutely essential to implement advanced IP network technologies such as QoS, Multicast, High Availability, and Security in order to provide real-time services like IPTV via IP backbone network. In reality, the existing commercial networks of internet service providers are subject to certain technical difficulties and limitations in embodying those technologies. On-going research efforts involve the experimental engineering works and implementation experience to trigger IPTV service on the premium-level IP backbone which has recently been developed. This paper introduces the core network technologies that will enable the deployment of a high-quality IPTV service, and then proposes a suitable methodology for application and deployment policies on each technology to lead the establishment and globalization of the IPTV service.

IP 주소에 대한 관리 및 특정 IP의 접속 허용 여부를 결정하기 위한 기능들은 기업 또는 학교 등 많은 곳에서 사용 된다. IP 정보를 기반으로 한 접속 허용 여부의 판단을 위한 정보의 보관은 파일 또는 데이터베이스를 이용하여 구 성되는데, 추가 정보에 의해 지속적으로 정보의 크기가 커질 수 있는 문제점을 가지고 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 IP 접속 허용 여부 정보를 비트맵 형식으로 저장하여 업데이트 여부와 관계없이 동일한 파 일 크기를 유지할 수 있는 파일 데이터베이스와 탐색을 위한 효율적인 알고리즘을 제안한다. 제안 파일 데이터베이 스는 IP 주소의 앞 3자리 옥텟을 이용하여 파일명을 생성하고, 나머지 옥텟 값은 비트맵 파일에 IP의 접속 여부를 판단 여부 값을 획득하기 위한 파일 내에서의 변위로 구성하였다. 파일 데이터베이스 탐색 성능은 SQLite와의 비교 를 통해 IP 접속 허용 여부를 위한 비트맵 파일 접근을 통한 차단 정보 확인 알고리즘이 효율적으로 구성되었음을 증명하였다.

The ability to mange IP addresses and decide whether to allow access to specific IPs is used in many places such as business and schools. Information storage, which determines whether to allow access based on IP information, is configured using a file or database, so you can continue to increase the size of the information. To solve this problem, this white paper proposes an efficient algorithm for file database and navigation, which can store IP access permission information in bitmap format and maintain the same file size whether or not it is updates. The proposed file database uses the first three digits of the IP address to generate a file name, and the remaining octets consist of displacements in the file to get a value indicating whether the IP is linked to the bitmap file. Compare file database scan performance with SQLite to show that the blocking information verification through bitmap file access has configured IP access efficiently.

The recent development of information and communication technology has a great impact on the audio/video industry. In particular, IP-based AoIP transmission technology and AVB technology are making changes in the audio/video market. Video signal transmission technology has been introduced to the market through a network, but it has not replaced the video switcher function. Video signals in the conference room or classroom are still controlled by the switching device. In order to switch input/output video devices, a cable that is not limited by distance must be connected to the switcher. In addition, the control of the switching device must be performed by a person who has received professional training. In this paper, it is a technology that can be operated even by non-experts by replacing complex video cables (RGB, DVI, HDMI, DP) with LAN cables and enabling IP-based video switching and transmission (Video Mirroring over IP: VMoIP) to replace video switcher equipment. We are going to do this study, I/O videos were controlled in the form of matrix and high-definition videos were transmitted without distortion, and VMoIP is expected to become the standard for video switching systems in the future.

Hyper Text Markup Language (HTML) is the main markup language for creating web pages and other information that can be displayed in a web browser. HTML5 is the fifth revision of the HTML standard. Its aim is to deliver almost everything you want to do without requiring additional plug-in. HTML5 first describes new tags for multimedia, which are the new audio and video tags. We produced an implementation of HTTP Live Streaming (HLS) for an IP camera by using elements of HTML5 for media playback. This implementation follows HLS standard in which we utilizes an open source library named FFMPEG. A conclusion of this paper is that live steaming on mobile devices over HTTP is achieved without any plug-ins.

Recently, the intelligent services demands interactions with the sensor networks, actuator networks, and context aware applications. Actuator network supports an infrastructure to have an immediate access to information for controlling the physical world and its objects using sensor networks and context aware applications. Actuator network middleware supports the command message transfer for controlling the behavior of the environment or physical systems. In this paper, we design and implement the actuator network middleware based on ID(IDentification) and IP(Internet Protocol) address for control the environment using multiple actuator devices. Also, this middleware assigns ID for identifying each actuator nodes, and uses an IP address for transferring control messages between application and actuator networks. And, the presented middleware provides to connect between actuator ID and IP address using the mapping table. We design the middleware using sequence diagram and state diagram, and implement it based on .Net framework. The middleware supports to transfer command messages between application and actuator networks.

In this paper, We studied the possibility of SoC(System On Chip) design using infrared image processing IP(Intellectual Property). And, we studied NUC(Non Uniformity Correction), BPR(Bad Pixel Recovery), and CEM(Contrast Enhancement) processing, the infrared image processing algorithm implemented by IP. We showed the logic and timing diagram implemented through the hardware block designed based on each algorithm. Each algorithm was coded as RTL(Register Transfer Level) using Verilog HDL(Hardware Description Language), ALTERA QUARTUS synthesis, and programed in FPGA(Field Programmable Gated Array).
