introduction of Network Set-top Box

Network set-top boxes (STB technology) is referred to as information appliances vital technical equipment. STB features from more than one frequency tuner and decoder jumped to a control terminal a lot of movies, multimedia events, news and other online databases. So, how to extend the set-top box function, improve quality, reduce production costs, optimize the product structure, has important implications for the development of emerging interactive television network.

Function:

      (1)Can be indicative of Customer Premises Equipment, CATV networks and program resources of the state; the user can use the TV screen displays messages and menus, and information services providercompany issued.

Advantage:

1, Whether to support the internal hard drive, a huge high-definition video capacity, easy to use hard driveregardless of the degree of dissemination, capacity, size, and playing on the fluidity has an unparalleled advantage. To the best built-in hard drive, external hard drive can only be used as USB transfer speed USBaffected by the rate of the general second only transfer about 20M, the situation will occur Caton screenwhen playing intense scenes rich, built-in SATA hard disk interface, the USB speed is 5 times to fullyadapt to the need for high-quality playback of high-definition movies.

2, Depending on its decoder chip, the latest professional HD player uses four main brands decoder chip,respectively Sigmal designs, Realtek, MSTAR, Amlogic.

 
3, The network function, can wireless Internet access and wireless networking also emphasize that aspectleap cable at home is definitely not feeling too good, to be wireless, hey, but also to high-speed wireless,remember to focus on the speed of wireless networking parameters, the highest speed wireless card 300M / S.

 
4, Simple operation, this should mention, after all, is going to tie the TV everyday use, if the operation is too complex, home for the elderly will not use, not self-inflicted boring? Complex operation is not complicated, you know look at the remote control, N keys do not choose a dense, English is also notelected. Simply go by.

5, Expansion capabilities, there is no expansion interfaces, can share files, usually a digital camera, DVshoot things with a television broadcast to share with family, with removable hard disk exchange videos, etc., are relying on the expansion interface. At least two extensions USB interface, or a connected wireless card after not enough.
