Remote wireless image transmission principle and method?
Remote wireless image transmission is a wireless transmission device that transmits audio and video signals from a signal source (a computer and an HD playback device) to a remote HDTV or HD projector, enabling lossless and non-delayed transmission of 1080P / 60 and 3D, No need to install software, plug and play. Its product transmission principle and method are as follows:
1. Product features and functions and technical indicators
Remote wireless image monitoring system, with Shenzhen wireless image transmission in the course of several years to develop, to understand the needs of users and the latest technology in the field of communications tracking and control, developed a complete industry-leading level of products, to achieve a technology leader, Functional and practical, stable and reliable, scalable and other functions, formed its own unique product features and styles, which are as follows:
Remote wireless video image monitoring system technical indicators
1.1 product features
1) To highlight a variety of on-site information collection capabilities, to achieve single or multiple video surveillance and other high-quality record of information storage, build a powerful system center monitoring platform;
2) The leading measured video indicators at home and abroad lead the indicators such as actual frame rate and network bandwidth utilization in many evaluation.
3) super network adaptability, in a variety of complex network conditions can effectively achieve video transmission. Maximize the use of network bandwidth, the maximum single CDMA1x uplink rate of more than 185kbps, the average frame rate of 15 to 20;
4) flexible parameter configuration strategy, you can choose the frame rate priority or quality priority, to adapt to the maximum complexity of the Internet environment, and the front-end device is set to record high-quality video D1 can store 15 frames per second Image, to ensure that the user video surveillance information security applications;
5) The embedded system design, software and hardware features modular, functional modules can be configured, almost all of the functional modules can be configured in the configuration file. Such as local records, automatic rate control, automatic frame rate control, automatic frame adjustment, etc .;
6) flexible single board communication, forwarding mechanism, when the wireless transmission is interrupted, the interrupted wireless channel can be automatically restored to achieve uninterrupted operation, greatly increasing the stability of the system;
7) Full control of wireless Modem, to achieve an efficient heartbeat detection mechanism, find dropped can quickly reconnect automatically;
8) Improve the system error detection function, when the system is running an error can be effectively restored;
9) The most suitable physical characteristics of the playing mechanism, video playback smooth and natural.
1.2 The main function
1) The standard H.264 image compression, real-time video up to 15 frames / second, the actual average frame rate higher than 12 frames / second;
2) Support 3G network, backwards compatible, automatically use 3G network transmission directly in the place or area covered by 3G network, and still use CDMA network transmission in areas not covered by 3G network;
3) High-definition video local storage, support remote control PTZ and focal length.
4) remote telemetry instructions in the case of mature conditions, you can achieve remote image transmission control.
1.3 technical indicators
Due to the characteristics of this type of equipment and industry requirements, this product is mainly developed for high-end users, due to the needs of users, using different environments, Shenzhen wireless image transmission for different users with personalized service, according to user needs special Custom development of functions. Remote wireless image transmission plays a great reference role in the future image transmission, which can not only be used in life, but also have a great effect on the use of investigation.
