Abstract
The utility model discloses a digital television receiving device utilizing a silicon tuner technology, comprising a main chip, a radio frequency input and a loop-out. A silicon tuner is connected between a demodulation module of the main chip and the radio frequency input and the loop-out, and the functions of high-frequency filtering, amplification, tuning, frequency locking and loop output of signals are realized through the silicon tuner. The digital television receiving device utilizing the silicon tuner technology has the beneficial effects that firstly, the production cost can be reduced, and the cost performance of the product is improved; in addition, due to small occupation area of the silicon tuner, an ultrathin and mini set top box appearance is possible, the device is convenient to be hung on a wall by users, space is saved, and current home furnishing requirement is satisfied. With continuous advancing of the market, the silicon tuner can certainly become the main trend of tuners.
Description
Technical field
The utility model relates to a kind of digital television receiving apparatus.
Background technology
At present the tuner that uses of top box of digital machine all is traditional CAN tuner, and cost is high, and volume is big, but fierce day by day along with the competition in market, product price, product appearance all are the key factors that obtains the broadcasting and TV approval.
Early stage silicon tuner is undesirable aspect some indexs, and particularly the dynamic range index is relatively poor, and is higher to the signal conformance index request of cable TV network, so the silicon tuner has stayed bad impression to operator.But the silicon tuner has had the history of more than ten years till now from being born, middle through constantly improving, and aspect performance index, begun to have met or exceeded traditional CAN tuner, and cost advantage is obvious.But traditional idea still hinders the use of silicon tuner in China Broadcast & Television market.The silicon tuner used in the electric wire modulator-demodulator a lot of years in a large number, can make things convenient for the miniaturization Design of top box of digital machine, also was convenient to the integrated design of system.
Summary of the invention
Deficiency to prior art; The utility model provides a kind of digital television receiving apparatus that utilizes silicon tuner technology; This digital television receiving apparatus substitutes the CAN tuner with the silicon tuner; Solved the traditional inferior position of CAN tuner STB aspect cost and product appearance simultaneously, and the correlation technique index also has certain advantage.
To achieve these goals, the technical scheme taked of the utility model is:
Utilize the digital television receiving apparatus of silicon tuner technology; Comprise master chip and radio frequency the input and encircle out; The input of the demodulation module of master chip and radio frequency and and encircle out between be connected with the silicon tuner, the silicon tuner is realized the High frequency filter, amplification of signal, tuning, frequency locking and loop output function.
Also be connected with outer memory module on the master chip.
Also be connected with the CAD module on the master chip.
Also be connected with display control module on the master chip.
Master chip links to each other with television set through the audio frequency and video output module.
The beneficial effect of the utility model: at first can reduce production costs; Improve the product price ratio, because silicon tuner area occupied is little, make ultra-thin mini STB outward appearance become possibility in addition; Make things convenient for user's wall built-up; Conserve space meets present household demand, will become the main flow of following tuner along with the continuous propelling silicon tuner in market.
Description of drawings
The functional-block diagram of Fig. 1, the utility model.
Embodiment
As shown in Figure 1; Utilize the digital television receiving apparatus of silicon tuner technology; Comprise master chip and radio frequency input (external coaxial cable) and encircle out; The input of the demodulation module of master chip and radio frequency and and encircle out between be connected with silicon tuner (silicon Turne), the silicon tuner is realized the High frequency filter (frequency-selecting), amplification of signal, tuning, frequency locking and loop output function.Also be connected with outer memory module (comprising Flash and Ram) on the master chip.Also be connected with the CAD module on the master chip.Also be connected with display control module on the master chip.Master chip links to each other with television set through the audio frequency and video output module.Directly substitute the CAN tuner with the silicon tuner on the hardware, accomplish High frequency filter (frequency-selecting) → signal amplification → tuning → frequency locking → loop output; Upgrade the corresponding driving of silicon tuner on the software, debugging gets final product then.
Claims (5)
1. utilize the digital television receiving apparatus of silicon tuner technology; Comprise master chip and radio frequency the input and encircle out; It is characterized in that; The input of the demodulation module of master chip and radio frequency and and encircle out between be connected with the silicon tuner, the silicon tuner is realized the High frequency filter, amplification of signal, tuning, frequency locking and loop output function.
