Abstract
The invention relates to a set-top box for a TV receiver, specifically a multi-mode digital TV receiver set-top box with receiving functions. According to technical proposal provided in the invention, the multi-mode digital TV receiver set-top box includes a main processor, a memory and a display-output module. The main processor extracts received and zipped video data in the memory and outputs to the display-output module. The invention is characterized in that the video data includes national standard DMB-TH digital TV ground broadcast signals, CATV signals, and broadband network IPTV. The set-top box includes a plurality of TV play modes applied inland at present, therefore service life of the product can be prolonged and waste caused by updating of the product is reduced.
Description
Technical field
The present invention relates to be used for the set-top box on the television receiver, specifically a kind of multi-mode digital television receiving set up box with multiple receiving function.
Background technology
At present, CATV set-top-box is more and more universal, but to the vast TV user of not opening the grass roots of cable TV, never a good television reception mode is following best television reception mode and worked the DMB-TH China Digital TV terrestrial broadcasting standard that puts teeth on August 1st, 2007.Be badly in need of the set-top box that a kind of energy is fit to this television reception mode for this reason.
Summary of the invention
The objective of the invention is to design a kind of multi-mode digital television receiving set up box, this set-top box has comprised the present domestic multiple pattern of televising, and therefore can prolong the operating period of product, reduces the waste that product constantly upgrades and causes.
According to technical scheme provided by the invention, described multi-mode digital television receiving set up box comprises primary processor, memory and shows output module, the video data of the compression that primary processor will receive is exported to the demonstration conveyor module after decompressing in memory, it is characterized in that described video data comprises: GB DMB-TH digital television ground broadcast signal; Cable TV signal; Broadband network IPTV; Wherein, GB DMB-TH digital television ground broadcast signal is handled by the DMB-TH receiver module, described receiver module comprises tuner, demodulator and microcontroller, tuner is given demodulator with the high-frequency radio frequency signal conveys that receives, by demodulator with the high-frequency radio frequency conversion of signals be the compression video data after flow to microcontroller again, by microcontroller with the compression video data flow to primary processor.
Input at primary processor is provided with video encoding module, and described cable TV signal is a digital signal, and by video encoding module digital signal is flowed to primary processor.Input at primary processor also is provided with the network uplink interface, and broadband network IPTV flows to primary processor again by the video data of the compression of network uplink interface reception far-end streaming media server.
Described set-top box also comprises the network downstream interface, and the computer expert crosses the network downstream interface and connects the internet.Input at primary processor is provided with the infrared remote control receiver module, is used to receive the signal that remote controller is launched.Show that output module comprises audio signal output part, high-definition video signal output and SD vision signal output; Show that output module flows to display with audio signal and vision signal.On primary processor, connect hard disk, be used to store the TV programme of recording.
Advantage of the present invention is: because a set-top box can be supported three kinds of receiving modes simultaneously, therefore in the area that does not have cable TV and broadband, can receive DMB-TH.In the place of opening cable TV and broadband access network, can also use the function of cable set top box and IPTV set-top box respectively.Charged performance recording (DVR) function of looking can be got off the television program record of liking at any time, can watch at any time later on.

Fig. 1 is a theory diagram of the present invention.
Embodiment
As shown in Figure 1, described multi-mode digital television receiving set up box comprises primary processor, memory and shows output module, the video data of the compression that primary processor will receive is exported to the demonstration conveyor module after decompressing in memory, it is characterized in that described video data comprises: GB DMB-TH digital television ground broadcast signal; Cable TV signal; Broadband network IPTV; Wherein, GB DMB-TH digital television ground broadcast signal is handled by the DMB-TH receiver module, described receiver module comprises tuner, demodulator and microcontroller, tuner is given demodulator with the high-frequency radio frequency signal conveys that receives, by demodulator with the high-frequency radio frequency conversion of signals be the compression video data after flow to microcontroller again, by microcontroller with the compression video data flow to primary processor.
Input at primary processor is provided with video encoding module, and described cable TV signal is a digital signal, and by video encoding module digital signal is flowed to primary processor.Input at primary processor also is provided with the network uplink interface, and broadband network IPTV flows to primary processor again by the video data of the compression of network uplink interface reception far-end streaming media server.
Described set-top box also comprises the network downstream interface, and the computer expert crosses the network downstream interface and connects the internet.Input at primary processor is provided with the infrared remote control receiver module, is used to receive the signal that remote controller is launched.Show that output module comprises audio signal output part, high-definition video signal output and SD vision signal output; Show that output module flows to display with audio signal and vision signal.On primary processor, connect hard disk, be used to store the TV programme of recording.
Wherein, the network uplink interface is used to connect internet, realizes the IPTV function, can carry out video request program (VOD), can surf the Net by browser; The cable TV interface is used to receive the cable television digital signal; Mobile TV module external antenna is used for the receiving digital television terrestrial broadcasting; Infrared remote controller is used to realize the set-top box remote controller function; The network downstream interface can connect the computer in the family, and computer can be surfed the Net by set-top box; Whole set-top-box system has the arm processor of powerful in function as primary processor; No matter be IPTV, or DMB-TH mobile TV or cable TV signal, performance recording can be got off to be kept in the local big capacity hard disk, so this set-top box also has the function of video cassette recorder (DVR); Output interface has audio frequency output, stereophony; Simulated television output interface (CVBS) is arranged, support the simulated television of present most of families; Also have the HDTV (High-Definition Television) interface, support digital TV in high resolution and big screen panel TV.
Primary processor adopts the semi-conductive i.MX27 dragon of Freescale pearl processor, and dominant frequency 400MHz, memory adopt mobile DDR SDRAM, and frequency 266MHz, processor core are ARM926.This primary processor has MPEG4/H.264/H.263 hardware compression unit, can decode efficiently and plays the video decode of IPTV, mobile TV; This processor also has enhanced multimedia to quicken processing unit, can carry out hardware handles such as preliminary treatment, reprocessing, rotation, convergent-divergent, mirror image, format conversion to video, can decode efficiently and play the MPEG2 video decode of cable digital TV, mobile TV.The TV signal of output CVBS720x576.
