Q:Classification of set top boxes
The selected chips are different, the hardware platform is different, and the other equipments and interfaces are different. This makes up a variety of STB. For example, in addition to the STB modem or a network card, constitutes a bidirectional function of set-top box; and hard disk constitutes a personal video recorder (PVR:Personal Video Recorder), of course, all of these needs with the set-top box software. On the same hardware platform, the set-top boxes of different applications can be formed by hosting different software, and the diversified STB meets the needs of different levels. Machine card separation and all-in-one machine is almost a natural pair. Large scale manufacturing TV not only improves the reliability of the product, but also reduce the production cost, and is the basis of large-scale manufacturing products are consistent, this is not only reflected in the hardware as well as software. Because of the diversity of software, manufacturers are unable to produce set-top boxes on a large scale like television sets. Therefore, to achieve scale manufacturing, CA is the first problem to be solved.
Q:ZTE intelligent set-top boxes b860a system space shortage how to do?
Clear memory or restore factory settingsPs: also do not know what to "ZNDS smart TV Forum" to find relevant information, can also recommend to the administrator for help, smart TV & set-top box to download and install the tangbe application store, expand resources, free to see all live on demand!

Q:How can I watch a movie without a set-top box?
The reasons why set-top boxes cannot watch movies are analysed below:1, network connection failure;2, the speed does not meet the needs of the movie;3 local network line fault;4, to see the film has been off the shelf.5, play the movie software has been released.
