introduction The next generation of rear seat entertainment systems must cover a wider range of data sources than automotive in-car entertainment systems, provide greater interactive support, and integrate more features into the automotive infrastructure, which will not only increase the value of OEM original equipment, but also increase The value of the equipment or retail equipment installed by the dealer. But it is clear that price is one of the key factors in the market for the next generation of rear seat entertainment systems now and in the future. Factors affecting prices include the overall cost of materials and hardware and software, which is mainly the development cost of software. This article focuses on how to reduce the overall cost of materials and software development workload. A good first impression is the key to a product's broad market acceptance, and the first impression has a lot to do with the ease of operation of the user interface. Obviously, even a very professional entertainment system will not be accepted by the market if the user interface is slow or disruptive to user commands. Market leaders have proven that a smooth, fast user interface is the key to product success. Adding 3D multi-window support can improve the overall ease of use of the system, but this requires an increase in image processing. 1 more features What features must the rear seat entertainment system support in the future? Of course, DVD-Video must be supported for a long time, which ensures that your child is happy on the way, and your existing CD library can be used for a long time. In addition to DVD-Video, Blu-ray will be the second disc standard supported by the system, as some movie discs are likely to use only the Blu-ray standard in the future. Blu-ray not only has superior audio and video performance, but also improves security. Using the blacklist saved on the disc, Blu-ray can prohibit playback of the disc on the "hacked" player. The growing opportunity to experience interactive content (such as games) on Blu-ray players is a strong evidence to support the growing market acceptance and is also a means of promotion. In addition to the CDs that carry entertainment content, the next-generation entertainment system must also consider the ability to play movies from other storage media via USB or e-SATA interfaces, such as SD cards, USB flash drives and mobile hard drives, which will inevitably enclose a large number of audio and video packages. The format is introduced into the rear seat entertainment system, so the system must support a large number of file formats, including DivX, XviD, AVI, RealMedia, 3GP, ASV, MOV, OGM, and so on. The rear seat entertainment system must also consider live broadcasts such as TV broadcasts, the most important of which are terrestrial TV broadcast systems such as DVB-T in Europe, ATSC in the US, ISDB-T in Japan or DTMB in China. In addition, mobile TV standards must also be considered, such as DVB-H in Europe, ATSC-M/H in the United States, T-DMB in South Korea, and CMMB in China. New TV standards will soon appear, such as the mobile satellite satellite broadcasting standard DVB-SH, which is similar to satellite radio broadcasting and is very popular in the United States. There will also be a new live TV channel in the market, which will transmit and broadcast TV programs through existing mobile phone infrastructure. Our younger generation also needs interactive entertainment content. Internet-connected data lines allow them to use a variety of services, such as YouTube, Twitter, Facebook and many other social networking sites. On this issue, it is clear that the entertainment system architecture also needs to accept a web browser to support common plugins. Only in this way can we provide more entertainment services to users, such as webcasting and Internet TV, and provide users with more kinds of entertainment content as much as possible. Also, why not increase the accessibility of the home media stream engine so that users can remotely access the content recorded at home? This eliminates the need for media content to be transferred or synchronized between the home and the car. Of course, these services require a data transmission service that is at least similar to EDGE or HSDPA, and the access service provider should provide a monthly or yearly charging policy. Once popularized, existing infrastructure will need to be improved or replaced by fourth-generation mobile communications LTE. In short, the rear seat entertainment system is a combination of residential professional entertainment system and mobile media source - a mobile home.
