Consumption Reduction Solution of TV News Broadcast System Based on Wireless Communication Network

At present, the news broadcast system using mobile network on the market provides the basic functions required by TV stations, but there are still many problems and shortcomings. In view of the main problems existing in the current system and combined with the actual needs of current users, this paper has preliminarily developed a news broadcast system based on 5G Live. The card frame adaptive strategy significantly improves the user experience by using gradual video frame buffering technology. Hardware codec technology significantly reduces the consumption of system resources; H.264 high-compression algorithm can reduce network bandwidth by 50% compared with MPEG-2 and MPEG-4 without a significant change in image quality. At the same time, the use of mobile video acquisition terminals in the system not only solves the problem that satellite broadcast vehicles cannot reach the site due to the lack of roads but also greatly reduces the cost of early deployment and late maintenance of the news broadcast system. This paper studies the card frame adaptive strategy, the system resource consumption reduction solution, and the deployment scheme of the mobile video and audio transmission terminal, which is of great significance to improve the design and research of the news broadcast system under the wireless network application and also has certain reference value for the design of other broadcasting and television solutions.

Optimization of geometric design parameters for a parallel plate fins heatsink of broadcast vehicle system

This paper researches a design process of a parallel plate-fins heatsink subjected to an impinging airflow in a broadcast vehicle system. First, it is demonstrated theoretically that the thermal conductance between the plate and the air stream can be maximized by optimizing geometric parameters. Next, the research studies the heat transfer theory across parallel plate-fins of the heatsink to optimize the geometric parameters. Those parameters are used to design a three-dimensional heatsink. In the next step, the design model simulates temperature under working conditions by using computational fluid dynamics (CFD). The simulation results show that the maximum temperature is smaller than the maximum permitted temperature of electronic equipment given by the manufacturer. Then, the design model is trial manufactured for testing before moving to mass production.

VLSI DESIGN OF EFFICIENT ENCODING TECHNIQUE USING ROLS METHOD FOR WAVE APPLICATIONS

The automotive industry is emerging aggressively towards the direction of advanced active safety. The automotive industry is aiming to work for the development of Dedicated Short Range Communication (DSRC) technology, for the purpose in vehicle-tovehicle and vehicle-to-roadside communication. To transmit the vehicular information and broadcast vehicle position, DSRC communication technology is adopt as bridge. This work is devoted to develop the encoding techniques for WAVE/DSRC applications. The DSRC standards generally make use of FM0 and Manchester encoding to achieve dc balance and enhancing signal reliability. Nevertheless, the diversity of coding between FM0 and Manchester codes limits the ability to design a fully utilize hardware architecture for both. The Reuse oriented logic simplification (ROLS) technique is proposed here so that the Hardware utilization rate (HUR) will reach to 100% from 57% for both encoding techniques. The proposed architecture will have less delay, area as compared to existing architecture. In this paper the architecture analyzed to reduce the number of components. Using both encodings the area, delay, and power is reduced in DSRC. The power consumption is 22132.181nW for both encoding, and area is 193µm 2 . The encoding technique in this work supports the DSRC standards used by several organizations of America,

Disaster Warning System in the Philippines Through Enterprise Engineering Perspective: A Study on the 2013 Super Typhoon Haiyan

In this research on disaster warning systems, the Philippines was selected to be a case study. The Philippines was hit by a particularly bad storm in 2013 Super Typhoon Haiyan. Here we focused on warning system process management from an enterprise engineering perspective. In understanding warning systems, it is necessary to know the essence of overall processes. The objective of this qualitative study is to determine the system’s essential components by using the Design and Engineering Methodology for Organizations (DEMO). This involves both assigning responsibility levels and utilizing both traditional means such as broadcast vehicles with speakers and radios and newer means such as Internet channels to disseminate warning information. The findings provide a simple model explaining the disaster-related organization and communication structure. They also contribute a practical aspect in the form of suggestions to planners and decision makers that may assist them in preparing mitigation plans for projected natural disasters.

A 525-Line Component Progressive Scan outside Broadcast Vehicle

Nippon Television Network (NTV) produced a 525-line component progressive scan outside broadcast (OB) vehicle, which is used for EDTV-II, a widescreen NTSC-compatible broadcast that started July 14, 1995, in Japan. The 525-line progressive scan is also employed as one of the scanning formats for standard-definition television (SDTV) in ATV. <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> This is purported to be the world's first progressive scan OB vehicle. It features a 16:9 progressive scan/4:3 interlaced scan switchable system, and it is an entirely digital component system from cameras to production switcher. The progressive signal output can be easily converted to any other scanning formats such as high-definition, or HD (1125/1035 interlaced) and ATV (1125/1080 interlaced, 750/720 progressive).
