    18、IntroductionDriver assistance systems are more and more common in road vehicles. From the beginning, cameras were part of this trend. Analogue cameras were used in the beginning, because of lower complexity of the first systems. With increasing demand for more advanced functionality, digital image p

    19、rocessing has been introduced. So-called one box design cameras (combining a digital image sensor and a processing unit) appeared in the vehicles.Currently, the market demands such systems with multiple functions. Even different viewing directions are in use. It seems to be common sense that 6 up to

    20、 12 cameras in a single vehicle will be seen in the next future. Out of this and the limitation in size, power consumption, etc. it will lead to designs where the cameras are separated from the processing unit. Therefore, a high performance digital interface between camera and processing unit is nec

    21、essary.This International Standard has been established in order to define the use cases, the communication protocol, and the physical layer requirements of a video communication interface for cameras, which covers the needs of driver assistance applications.The video communication interface for cam

    23、s including wired and wireless connections by using existing adaption layers, and is compatible with AUTOSAR.This part of ISO 17215 is related to the general information and use case definition. This is a general overview International Standard which is not related to the OSI model.To achieve this,

    24、it is based on the Open Systems Interconnection (OSI) basic reference model specified in ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers. When mapped on this model, the protocol, and physical layer requirements specified by this International Standard, in a

    30、layers 1 to 4 for the video communication interface for cameras. It complements ISO 13400-2 and ISO 13400-3 and adds the requirement for video transmission over Ethernet.ISO 17215-2 and ISO 17215-3 (OSI layer 5 to 7) services have been defined to be independent of the ISO 17215-4 (OSI layer 1 to 4)
