Analysis of high-definition video application technology

modern society is developing with each passing day. More and more applications of video technology make our life more clear and convenient. For example, the integration of set-top box and monitoring technology will bring more convenience to our life. Imagine that viewers watching wonderful events through high-definition TV at home can use cameras to monitor their own doors, The picture in picture window of TV will show the visiting friends under their globalization strategy. You can open the door for your friends without getting up, so you won't miss the wonderful game picture; With the support of object recognition technology, digital cameras can improve our quality of life, because it can ensure that everyone in the camera lens opens their eyes before taking photos; And our personal safety will also be better protected, because cars can help drivers see the road clearly in the fog, or give an alarm when the driver may hit us from behind; Portable wireless medical devices can help save lives because they can help doctors make detailed and accurate diagnosis on the way to the hospital

in the past, engineers had very limited options when implementing digital video. Hardwired and ASIC based solutions always limit the use and function of devices, and also limit their adaptability. Although the flexibility of special devices is slightly higher than that of ASIC, their utility is still limited in the face of the rapidly changing multimedia standards and applications. Although programmable platforms are the most flexible way to extend the service life of products, in order to enter the digital video technology market, they often need huge software development investment, for example

the primary difficulty in embedding digital video into applications is that the complexity of implementing video is far more than simple image and audio compression and decompression. Digital video can adopt various forms and formats. Developers need to support complex configurations and various aspects, such as different resolutions/display sizes, different bit rates, real-time problems, and even the reliability of video sources (for example, the difference between video streams from hard disk drives and wireless communication links). Even those seemingly simple tasks, such as efficient management of audio/video synchronization and reliable video transmission after saving the original data on the IP network, will still make developers wonder how to identify and calculate the specific yield strength. Although many application developers are overjoyed by some devices, they have to support a variety of standards, including those new standards that must be developed. To see the importance of this flexibility, just think about H.26? The rapid deployment and widespread popularity of video codec

the main obstacle facing many engineers is the lack of a digital video development platform with sufficient performance, low cost, high flexibility and easy access. For engineers who want to integrate video in new applications, low-cost off the shelf video subsystems must be used to reduce the complexity of video design. However, with TI's Da Vinci technology, all problems can be solved

what is da Vinci technology

the successful implementation of digital video requires the latest progress of four elements: processors, development tools, software and system expertise. Because it can realize digital video, audio, voice and voice technology in the platform integrating these four elements, Da Vinci technology can lay the foundation for the current transformation of digital video

Da Vinci technology makes full use of TI's 25 years of professional digital signal processing and integrated circuit technology to provide system on chip (SOC). This system is carefully optimized for flexible digital video implementation, has industry-leading performance, and integrates programmable digital signal processor (DSP) core, ARM processor and video acceleration coprocessor. With efficient processing power, memory, i/o bandwidth, balanced internal interconnection and dedicated peripheral combination, SoC Based on Da Vinci technology can provide ideal core power for video applications at the lowest cost

in order to truly enable developers to overcome the initial obstacles and speed up the process of product launch, it is far from enough to develop and implement the basic chips and software of digital video. Developers need not only processors, but also ideal code that can be directly put into production. In other words, in order to meet the specific needs of their applications, developers also need hardware and software that have been integrated into configurable or easily programmable digital video subsystems

just as the transition from assembly language to C language enables developers to fully develop higher-level functionality, Da Vinci technology enables developers to get rid of the specific technical details of digital video. Now, developers no longer need to know the details of implementing specific codec engines (such as MPEG-2, H.263, wma9) in their video applications. Using the API that allows developers to use the ideal codec without modifying the upper application code, such as Ti Da Vinci DM6446 development board (consult:,:), we can significantly simplify the specific low-level details of video codec processing

getting rid of the trouble of codec is an important step in the widespread popularity of digital video. When developers can base on the functionality of previous development, innovation has come to them. Dm357 is a low-cost arm based processor, which includes D1 resolution duty-free H.264 codec for video compression, as well as MPEG-4, JPEG and G.711 codecs. There is no need to pay license fees and copyright fees to Ti. An integrated EMAC can help developers reduce BOM costs. You can learn about dm357 development board products (consultation:,:). For many years, Ti and other companies have always been committed to integrating functions in silicon chips, laying the foundation for devices that exceed their functional expectations, while reducing the amount of work required to achieve the desired goals. For example, the advent of DSP has driven decades of technological innovation by providing a computing engine that significantly accelerates signal processing tasks

by using da Vinci technology, we can achieve a new level of innovation again. It is the advent of DSP that brings computing acceleration, so Da Vinci technology will provide application acceleration based on TI's DSP. Developers no longer need to understand the mechanism behind various audio, video, video and voice codecs

for developers who want to rely on DSP, opportunities still exist. However, Da Vinci has made it an alternative rather than a necessity. By providing software that can be put into production at any time, such as hardware drivers, manually optimized codec, and application code for managing audio/video synchronization and data flow in the network, Da Vinci technology enables developers to achieve first-class video functions without knowing how to program DSP.
