Description
Technical field
The utility model relates to a kind of system being applied to Digital TV Receiving, WIFI video push, intelligent terminal APP application; Be specifically related to a kind of apparatus of digital television receiving.
Background technology
Along with popularizing of Digital Television, the Set Top Box such as digital satellite television set-top box, digital cable box and digital terrestrial television Set Top Box have entered each family in a large number, present stage is supplied to the disposal ability of master chip in the receiver of user from strength to strength, but most of receiver only has a tuner, a receiver can only connect a display device and play a programs; In addition, in the development family of network technology and mobile communication technology, the frequency of utilization of smart machine is also more and more higher, user is more and more higher to increasing the functions such as video recording, playback, personalizationization selection, multi-screen interactive in apparatus of digital television receiving, and along with the maturation of WiFi technology, the establishment of family lan is popularized, utilize WiFi technology and intelligent terminal APP to apply, allowing digital television receiver become family's programme televised live center becomes possibility.
And traditional apparatus of digital television receiving has the development that above-mentioned limitation has hindered digital television business, therefore, be necessary to propose a kind of novel apparatus of digital television receiving.
Utility model content
Technical problem to be solved in the utility model is: for the limitation of the apparatus of digital television receiving in conventional art, proposes a kind of novel apparatus of digital television receiving.
The utility model solves the problems of the technologies described above adopted scheme: a kind of apparatus of digital television receiving, comprises digital TV receiver group and antenna modules; Described antenna modules is connected by cable with described digital TV receiver group; Described digital TV receiver group comprises condition reception unit and at least two channel decoding unit connected successively, source coding unit, signal output unit; Described condition reception unit is connected with source coding unit; Described digital TV receiver group also comprises WIFI encrypting module, and described WIFI encrypting module is connected with family WIFI local area network signal.
Further, described antenna modules comprises: antenna and/or optical fiber and/or amplifier.
Further, described channel decoding unit comprises tuner and coupled channel demodulation module.
Further, described source coding unit comprises the MIPS demultiplexing control module, decoding decompression module and the audio frequency and video processing module that are connected successively.
The beneficial effects of the utility model are: the video push function that 1) can complete limited device in family WIFI local area network (LAN), and demodulation while of can realizing multi channel, meets kinsfolk's individual demand; 2) condition receiving system can pass through the signal such as antenna or the mode such as optical fiber or amplifier receiving satellite signal, wire signal and surface wave signal, can realize the Signal transmissions of various ways; 3) program push is limited in encoding/encryption transmission in family lan, and copyright protection and the anti-copy that can realize Digital and analog port copy.
Accompanying drawing explanation
Fig. 1 is the apparatus of digital television receiving fundamental diagram in the utility model embodiment.
Embodiment
The utility model is intended to the limitation for the apparatus of digital television receiving in conventional art, proposes a kind of novel apparatus of digital television receiving.It comprises digital TV receiver group and antenna modules; Described antenna modules is connected by cable with described digital TV receiver group; Described digital TV receiver group comprises condition reception unit and at least two channel decoding unit connected successively, source coding unit, signal output unit; Described condition reception unit is connected with source coding unit; Described digital TV receiver group also comprises WIFI encrypting module, and described WIFI encrypting module is connected with family WIFI local area network signal.
Embodiment:
As shown in Figure 1, in this example, apparatus of digital television receiving is formed primarily of digital received module and antenna modules; Digital received module internal has the channel decoding unit of 3 passages be connected successively, source coding and signal output unit; Digital received module internal also comprises condition reception unit and power-supply system, wherein condition reception unit and power-supply system are all connected with source coding unit, and power-supply system provides electric energy for digital receiver module and antenna modules, modulate output and communicate to connect with source coding; In this example, digital received module also has wifi encrypting module, realizes digital received module be connected with intelligent terminal by wifi encrypting module.
Antenna modules comprises antenna, optical fiber, amplifier, can pass through the signal such as antenna or the mode such as optical fiber or amplifier receiving satellite signal, wire signal and surface wave signal.
Channel-decoding includes tuner and channel demodulation, and channel-decoding can carry out the decoding process of signal to satellite-signal, wire signal and surface wave signal, and channel demodulation can be mediated process to decoded signal.
Source coding comprises the control of MIPS demultiplexing, decoding decompress(ion) and the process of image procossing audio frequency.The above-mentioned components and parts of source coding can carry out source coding process to the signal after prevention, obtain video, audio frequency and data format file needed for playing.
Signal output unit can export as the form such as video, audio frequency, also can realize the interactive type communication of data (image, word etc.).
The operation principle of above-mentioned apparatus of digital television receiving is:
The signals such as antenna modules receiving satellite signal, wire signal and surface wave signal.The channel-decoding of digital received module internal and source coding carry out tuning, conversion, demodulation, decoding, the process such as descrambling and demultiplexing to signal successively, signal data after process to be mainly stored in static memory in Static and dynamic two kinds of modes and in dynamic memory respectively, its main sound state storage format be MPEG2, MPEG4, MPEG5, H.264, AVS etc.When carrying out file output, by the Voice & Video file output in dynamic memory, the data information in static memory can be carried out data output by data transfer mode on the other hand on the one hand.
This digital TV receiving system can also be communicated to connect by wifi module, intelligent terminal and digital received module, and realizes the video push in Set Top Box.
