Digital TV shifting is currently taking place in many places, and many places are moving in a two-way direction. The hidden dangers brought by CA's smart card CW sharing to operators have begun to appear, which has formed a consensus in the industry. Satellite digital TV operators suffer from piracy and sharing of smart cards. Now with the further expansion of the two-way network set-top box business and the increase in the value of digital TV programs, more and more cable operators have begun to pay attention to security issues, especially with the popularity of two-way digital TV set-top boxes, the security of smart card CA Have to be re-examined.
So, what impact does smart card CA have on a two-way network set-top box?
From the perspective of smart card sharing, a two-way network set-top box provides the basic conditions for network transmission for sharing. The principle of smart card CA sharing is to insert an original smart card into the first set-top box, and then the second and third set-top boxes can access the original smart card by accessing the IP address of the first set-top box. And these are the easiest to implement through the network. The first set-top box itself can be equivalent to a server, it can be connected to the second, third, fourth ... nth set-top box, used within the family, within the unit and within the hotel to share is not a problem. In this way, these set-top boxes do not need to buy a smart card, and only need to share the smart card of the first set-top box through the network to watch the digital TV program. Most families now have two or even three TVs. If you use this shared method to watch digital TV programs, plus the number of shares shared within the unit and within the hotel, the operator's losses can be imagined.
The previous set-top box has no network port and belongs to a one-way box. If you want to share, you must connect an external module with a network. Even so, in the high-value satellite TV market, there are still many manufacturers doing this underground market and have made great profits. This year's No. 1 document issued by the State Council has encouraged the two-way transformation of TV operators. Currently, cable digital TV is moving to two-way network set-top boxes. Many operators are planning or sending two-way set-top boxes with network interfaces. If these are set-top boxes, To upgrade, you can directly let these set-top boxes have network sharing function, let other set-top boxes share the smart cards inserted in the set-top box through the network, and thus the safety and benefit loss caused by the operators have to re-consider the deployment problem of CA. The development of digital TV has now put forward higher requirements for the innovation of CA security system. For the entire broadcasting industry, it is an urgent problem to solve CA security system to a new level.
