Abstract
The utility model relates to the TV technology, in particular to a TV set-top box. The utility model discloses a TV set-top box which is embedded with a wireless network module. The technical proposal of the utility model is as follows: the set-top box comprises a CPU and the wireless network module. The set-top box is characterized in that the wireless network module is embedded in the set-top box; the wireless network module is connected with the CPU; the wireless network module comprises an MAC, a memory and a high frequency circuit; the MAC is connected with the CPU; the memory is connected with the MAC; and the high frequency circuit is connected with the MAC. The technical proposal of the utility model is used for a bidirectional set-top box, can reduce the cost of the bidirectional set-top box, does not occupy the USB interfaces of the set-top box, and omits complex network wiring.
Description
Technical field
The utility model relates to TV tech, particularly TV set-top box.
Background technology
High speed development along with digital television techniques, various TV set-top box have entered people's family more and more, comprise the satellite television set-top box that is used to receive satellite television, be used to receive the CATV set-top-box of cable television system digital signal and be used to receive DVB set-top box of ground digital television broadcast etc.These TV set-top box not only need to be connected with television set in the family, need connect antenna system, satellite receiving system etc. toward contact, and its installation site is generally more fixing.On the other hand, have the function that connects the Internet and become the universal demand of people set-top box.At present to connect the main flow mode of network be integrated Ethernet card in inside to bi-directional set-top box, connects router or Cable Modem by netting twine, realizes and being connected of the Internet with this.The problem of this mode maximum is the putting position that wired connection has limited equipment such as set-top box and television set, simultaneously loaded down with trivial details wiring has brought inconvenience also for people's life, will be the development trend of following bi-directional set-top box so have the set-top box of wireless networking capabilities.The realization of set-top box wireless networking capabilities at present is to adopt set-top box to add the method for external radio network interface card (wireless network module) substantially, the USB interface that adopts set-top box that is connected of set-top box and wireless network card.This method can take very limited set-top box USB interface, and the price of external radio network interface card is not low simultaneously, buys separately and can reduce the interest of user to digital television application.Above-mentioned situation all is unfavorable for the development of Digital Television industry.
The utility model content
Technical problem to be solved in the utility model just provides a kind of TV set-top box of built-in wireless network module.
The utility model solve the technical problem, and the technical scheme of employing is, a kind of set-top box comprises CPU and wireless network module, it is characterized in that, described wireless network module is built in set-top box, and described wireless network module is connected with described CPU;
Concrete, described wireless network module comprises MAC, memory and high-frequency circuit, and described MAC is connected with CPU, and described memory is connected with MAC, and described high-frequency circuit is connected with MAC;
Further, described memory is the SDRAM memory and the EEPROM of described set-top box;
More specifically, described set-top box is CATV set-top-box or satellite television set-top box.
The beneficial effects of the utility model are, wireless network module coil insertion device top box has reduced the cost of bi-directional set-top box, does not take the set-top box USB interface, and has saved complicated network layout.
Description of drawings
Fig. 1 is the structure chart of embodiment.
Embodiment
The utility model adopts embedded technology, and wireless network module is built in set-top box, constitutes incorporate bi-directional set-top box.Wireless network module is built in set-top box, can share the part software and hardware of set-top box, not only can reduce product cost, and structure is compact more.
Embodiment
The set-top box that this is routine comprises CPU (central processing unit), SDRAM (static memory), EEPROM (electricity can be examined except that memory), FLASH memory and wireless network module, as shown in Figure 1.Wireless network module is built in the set-top box, and is connected with CPU by bus, communicates and exchanges data.This routine wireless network module comprises MAC (medium access controller), memory, high-frequency circuit and antenna, and MAC links to each other by bus with CPU, and high-frequency circuit is connected with MAC.In this example, wireless network module and set-top box are shared SDRAM and EEPROM.
This routine set-top box is main control chip with CPU, links to each other with the MAC chip of wireless network module by control bus; The MAC chip carries out reading and writing data by data/address bus to the SDRAM in the set-top box, EEPROM simultaneously.When enabling wireless network card, set-top box CPU reads NIC driver, wireless standard and agreement in FLASH, and the control wireless network module is visited wireless route, WLAN (wireless local area network) in the connection.When sending data, set-top box CPU deposits data to be sent among SDRAM or the EEPROM in, and control MAC chip is visited this memory; After the MAC chip reading of data, carry out the CCK modulation, and signal is launched by antenna through high-frequency circuit.When receiving data, high-frequency circuit carries out the CCK demodulation with the signal that antenna receives, and the MAC chip deposits data among SDRAM or the EEPROM in, and the notice set-top box CPU is visited this memory data.
The technical solution of the utility model goes for CATV set-top-box, satellite television set-top box etc.
