Description
Technical field
The utility model belongs to the digital television techniques field, relates in particular to a kind of digital television receiving apparatus.
Background technology
Wireless IPTV set-top box and digital moving-tv player have appearred in the market, but the two only adapts to application scenario separately, the IPTV set-top box generally can only be used in fixing position, be not easy to move, and the digital moving-tv player, can only be in outdoor application, in case in the inlet chamber, will be owing to the signal reason, often can not normal play.
The wireless IPTV set-top box employing WIFI LAN that prior art provides can only be in the video display entertainment of indoor enjoyment high definition, the digital moving-tv player can only (China Mobile Multimedia Broadcasting CMMB) watches digital television program by China Mobile's DMB outdoor.In a word, prior art can not solve the problem that all can normally watch video frequency program at indoor and outdoors.
Summary of the invention
The purpose of this utility model is to provide a kind of digital television receiving apparatus, is intended to solve the problem that the digital TV integrated machine of prior art can not all can normally be watched video frequency program at indoor and outdoors.
The utility model is achieved in that a kind of digital television receiving apparatus, comprises display module, and described digital television receiving apparatus also comprises
Receive the mobile digital multi-media broadcast module of mobile digital TV signals by mobile digital multi-media broadcast;
Receive the WIFI module of network video signal by the WIFI network;
Be connected respectively with described display module, mobile digital multi-media broadcast module, WIFI module, be used to handle mobile digital TV signals that receives from described mobile digital multi-media broadcast module or the network video signal that receives from described WIFI module, and it is delivered to the processor that described display module shows;
Be connected with described processor, be used for moving and depositing the storage inside module of program.
In the utility model, can receive digital moving-tv signal and network video signal respectively by mobile digital multi-media broadcast module in the digital television receiving apparatus and WIFI module, the user all can normally watch video frequency program in indoor and outdoor.
Description of drawings
Fig. 1 is the structural representation of the digital television receiving apparatus that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
In the utility model embodiment, can receive digital moving-tv signal and network video signal respectively by mobile digital multi-media broadcast module in the digital television receiving apparatus and WIFI module, the user all can normally watch video frequency program in indoor and outdoor.
Fig. 1 shows the structure of the digital television receiving apparatus that the utility model embodiment provides, and for convenience of explanation, only shows the part that the utility model embodiment is correlated with.This digital television receiving apparatus comprises: processor 11, storage inside module 12, display module 13, mobile digital multi-media broadcast module (being called for short the CMMB module) 14, WIFI module 15.Wherein, processor 11 is used for handling from the mobile digital TV signals of CMMB module 14 receptions or the network video signal that receives from the WIFI module, and it is delivered to display module 13 show, SIPROS interface and response user's various operations; Memory module 12 be used for operation, deposit program and data, wherein in the utility model embodiment, memory module 12 is used DDRII synchronous DRAM (the Synchronous Dynamic Random AccessMemory of 128MB, SDRAM) and the Nand FLASH nonvolatile flash memory memory of 128MB, consider the operating system that to support WINCE simultaneously, make the interface friendly more, be convenient to operation, use, the memory module 12 in the utility model is selected bigger memory capacity; Display module 13 uses the precious VGA display screen of 3.5 cun system; The CMMB module is used for receiving mobile digital TV signals, selects the CMMB module of spreadtrum company in the present embodiment for use, and its hardware connecting interface is selected the interface mode of USB for use; WIFI module 15 is used for receiving network video signal, selects the WIFI module of USI company in the present embodiment for use, and based on the Marvel kernel, its hardware connecting interface is selected the interface mode of SPI.
The digital television receiving apparatus that the utility model embodiment provides also comprises: the button control module, have only switching on and shutting down button and reset key, and other function operations all can realize by touching touch-screen; Data interface module, the MINI USB interface of selection standard, outer memory module uses storage card, select the TF card, heap(ed) capacity is 8GB, the user use storage card can be by data interface module from digital television receiving apparatus foradownloaded video signal or uploaded videos signal to digital television receiving apparatus, power management module is all modules shown in Figure 1, button control module and data interface module power supply; Lithium battery is selected the above high-capacity lithium battery of 2000MA*H for use, and guaranteeing the normal operation of all modules shown in Figure 1, button control module and data interface module, and wherein said power management module can be controlled the charging of lithium battery.
Concrete workflow is as described below: when digital television receiving apparatus is in when outdoor, owing to there is not wireless network, the user can only watch the program of mobile digital TV by CMMB module 14, if the user will open the correlation function of wireless IPTV, then there is not wireless network in prompting, can only watch the mobile digital TV program outdoor; After in the inlet chamber, because the signal weakening of CMMB, when signal strength signal intensity was not enough to watch the mobile digital TV program, then digital television receiving apparatus pointed out user CMMB signal strength signal intensity not enough or no signal, the search radio area network receives and the playing network vision signal by WIFI module 15.Because the network video signal of depositing on the digital video signal of CMMB broadcasting now and the wireless internet network can't be compatible, so the program that indoor and outdoor is watched is different, if the in real time synchronous program of CMMB is arranged on the network later on, can watch identical program in indoor and outdoor.If at the indoor program of watching wireless IPTV, when when outdoor, the signal strength signal intensity that detects WIFI is not enough, prompting user radio local area network signal insufficient strength, (CMMB is a broadcast singal, can not support the program of wireless IPTV please to preserve this video node, so can only preserve the current node of watching here, in order to continuing to watch next time), when the user watches next time, can continue to watch from this node.
In the utility model embodiment, can receive digital moving-tv signal and network video signal respectively by mobile digital multi-media broadcast module in the digital television receiving apparatus and WIFI module, the user all can normally watch video frequency program in indoor and outdoor.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
