The intellectual property rights of DTV-CI are clear and there is no patent requirement. The current status of intellectual property rights will not restrict the development of the industry, and the next step of our independent intellectual property rights will accelerate the development of the industry. The PCMCIA machine card separation adopts the technology development route of introduction, absorption, digestion and re-innovation, which helps to develop the digital TV industry as soon as possible and promote the healthy growth of the entire digital TV industry chain. This article refers to the address: http:// Basic CAM card, compatible with DVB-CI / PCMCIA From the perspective of the development trend of digital TV abroad, the card separation mode using the PCMCIA interface is a major direction. Whether it is the US POD standard or the European DVB-CI standard, the basic physical interface is the PCMCIA interface. PCMCIA is Bus-based interface technology is ideal for TS stream processing. South Korea adopts the US POD interface, and the PCMCIA machine card separation in Taiwan shows that it is widely used. Secondly, the machine card separation is a module technology system, not just the PCMCIA interface. The PCMCIA interface solution has high industry support and is supported by DVB mainstream chip manufacturers. After practical tests, it has high reliability, no technical risks, and has been recognized and supported by CA manufacturers. It has high technology maturity and supporting resources. Well, it is an internationally versatile and very ideal technical solution. This kind of scheme is the lowest comprehensive cost scheme for China's manufacturing industry. It is easy to go abroad and is beneficial to the global operation of China's digital TV enterprises. The impact on the industry chain is minimal and the interests of all parties are not damaged.
