Abstract
The utility model relates to a digital television top box based on wireless telephone. It mainly comprises a remote controller and a digital television top box. The utility model uses a wireless telephone as its interface controlling center and is matched with a digital television top box controller. The utility model can be used as a remote controller and a wireless telephone as well. The inner part of the digital television top box is integrated with an MODEM connected with PSTN, and the MODEM connects the television with the interconnect network. The audiences can use the remote controller to control the digital television top box to watch the digital television programs. The utility model is also a wireless mobile phone, and users can use the wireless mobile phone to call or receive. The remote controller is simultaneously a wireless mouse, and the users can play on the internet through the television. In addition, the signal transmission network of most television is totally provided with unidirectional characteristic at present, so the users must use the telephone to order programs to realize video on demand. As a result, the remote controller adopting the digital television top box based on wireless telephone becomes a more convenient handling tool for people's amusement, and the utility model is provided with practical value and generalization value.
Description
Technical field
The utility model relates to the digital TV set-top box field, particularly based on the top box of digital machine of cordless telephone.
Background technology
Because digital audio/video encoding compression technology rapid development causes a TV signal turns to numeral from simulation revolution.Appointment along with Digital Television respective standard and standard, Digital Television progresses into family, but because the user side use substantially all is simulated color television, can't receiving digital signals, therefore a kind of receiving system of needs is taken on the bridge between the two, Here it is set-top box STB, it is the visual plant that broadcast medium realizes receiving terminal after the digitlization, generally places on the television set.Early stage set-top box is meant that spectators control watching of some charge program by remote controller or button.In recent years, along with developing rapidly of digital broadcasting and internet, set-top box only needs to link to each other with telephone wire with television set, the dream that can enjoy a trip to Internet and carry out video request program at home by TV by remote controller or Wireless Keyboard realization.But the drawback that adopts this kind mode maximum is to be connected inconvenience with telephone wire.
Summary of the invention
The utility model provides a kind of top box of digital machine based on cordless telephone in order to overcome the problem that above-mentioned technology exists.Spectators can use its remote controller to come the controller top box, watch digital television program.Remote controller also is the mobile phone of cordless telephone, and the user can dial or receive calls.Remote controller still is a wireless mouse simultaneously, can enjoy a trip to the Internet by TV.In addition because present most TV signal transmission networks all have unidirectional characteristics, realize video request program, need come request program by phone, therefore adopt top box of digital machine remote controller to become the convenient operation tool of people's amusement and recreation based on cordless telephone.
Top box of digital machine based on cordless telephone, mainly comprise remote controller and top box of digital machine, with the cordless telephone is the Interface Control center, be equipped with the digital TV set-top box controller, remote controller is by speech signal MIC input, analog-to-digital conversion module A/D, MCU MCU coding, D/A converter module D/A, loudspeaker, keyboard, radio-frequency front-end and antenna are formed, with MCU MCU be encoded to the center respectively with A/D, D/A, keyboard, radio-frequency front-end links to each other, MCU MCU coding place connects a LCDs LCD, status display apparatus as cordless telephone, set-top box is a core with quadrature amplitude modulation QAM, respectively with cable TV CATV signal input output end, keyboard, modulator-demodulator MEDEM links to each other, wherein link to each other by digital interface between MCU and the QAM, exchange control signaling, A/D then is connected with the MODEM nest plate with D/A, with speech signal feed-in PSTN public network.
The utility model is the Interface Control center with the cordless telephone, be equipped with the digital TV set-top box controller, both having can be used as remote controller uses, it is again a cordless telephone, the inner integrated modem that connects Public Switched Telephone Network PSTN of set-top box couples together television set and Internet.Spectators can use a teleswitch the controller top box, watch digital television program.Remote controller also is the mobile phone of cordless telephone, and the user can dial or receive calls.Remote controller still is a wireless mouse simultaneously, can enjoy a trip to the Internet by TV.In addition because present most TV signal transmission networks all have unidirectional characteristics, realize video request program, need come request program by phone, therefore adopt top box of digital machine remote controller to become the convenient operation tool of people's amusement and recreation based on cordless telephone.Therefore has practical and popularizing value.
Description of drawings
Fig. 1 is the remote controller composition frame chart.
Fig. 2 is the top box of digital machine composition frame chart.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings.
The utility model mainly is made of two parts: remote controller and top box of digital machine.
The remote controller composition frame chart as shown in Figure 1.User's speech signal is imported by MIC, be converted into numeral through analog-to-digital conversion module A/D, go into radio frequency front end and antenna by MCU MCU coding rear feed, reception process is same as described above, through antenna, radio-frequency front-end, MCU, D/A converter module D/A, the feed-in sound horn, KEYPAD is a dialing keyboard, also is the button of remote controller keyboard and wireless mouse.LCDs LCD is then as the status display apparatus of cordless telephone.
The top box of digital machine composition frame chart as shown in Figure 2.Set-top box is core with QAMi5516, and the sound of the cable TV CATV signal that tuner is next clear quality of outputting standard after quadrature amplitude modulation QAM decoding, deciphering, video are to general television set.Radio-frequency front-end, MCU, A/D and D/A form the interface of cordless telephone stiff end, wherein pass through digital interface between MCU and the QAMi5516, exchange control signaling, and A/D then is connected with the MODEM nest plate with D/A, with speech signal feed-in PSTN public network.The user also can dial up on the telephone by MODEM, uses television set to enjoy a trip to the Internet and carries out interactive service such as video request program at home.
