Abstract
The utility model relates to a digital television set-topbox, in particular to a digital television set-topbox capable of realizing set to set upgrading data, which comprises a main set-topbox and a sub set-topbox, wherein the main set-topbox and the sub set-topbox are connected through a serial port wire, and set to set upgrading modules, LOADER program modules and data transmission modules are arranged both in the main set-topbox and the sub set-topbox. The utility model can realize the software upgrading, and can transmit the software or program data of one set-topbox to another set-topbox for realizing the software upgrading or avoiding secondary program searching.
Description
[technical field]
The utility model relates to digital TV set-top box, specifically is meant the digital TV set-top box of the machine of can realizing to the machine upgrade data.
[background technology]
At present, set-top box technique is developed faster, is being used widely in a lot of environment, but existing digital TV set-top box, and it can only upgrade to it or carry out aerial upgrade by OTA at data upgrading or this piece of software upgrading by the computer instrument.Except these two kinds of upgrading modes, can't upgrade to loom.
Digital TV set-top box will realize that upgrading must have computer equipment or headend equipment just can upgrade in the prior art, otherwise can't carry out the upgrading of program data.Set-top box file in download data and other data message can't be passed through, the multi-functional requirement of present user can not be satisfied.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of digital TV set-top box that realizes machine to the machine upgrade data.。
The utility model solves the problems of the technologies described above by the following technical solutions:
Can realize the digital TV set-top box of machine, comprise that a primary set-top box, is from set-top box the machine upgrade data; This primary set-top box be connected by Serial Port Line between the set-top box; Described primary set-top box with all have machine in the set-top box to machine upgrade module, LOADER program module, data transmission module.
Advantage of the present utility model is: connect two set-top box by Serial Port Line, not only can carry out software upgrading, can also be sent to the software of a set-top box or program data on the other set-top box, realize software upgrading or avoid the search again of program.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the utility model structural representation.
[embodiment]
See also shown in Figure 1ly, can realize the digital TV set-top box of machine, comprise that a primary set-top box, is from set-top box the machine upgrade data; This primary set-top box be connected by Serial Port Line between the set-top box; Described primary set-top box with all have machine in the set-top box to machine upgrade module, LOADER program module, data transmission module.
The operation principle of set-top box is: tuner is by connecting the antenna receiving digital signals, and front end passes through I under the control of main control chip innernal CPU
2The C bus tuner be tuned to certain digital channel, carry out demodulation by demodulation chip, become TS stream input main control chip to decode ground GB digital demodulation signal.The transport stream that demodulates (TS stream) data are by transmitting stream interface input main control chip.TS flow data in the main control chip is isolated sound, video PES stream by the demultiplexing functional module, under the control of frequency division multiple access, be sent to inner audio decoder and Video Decoder, the demultiplexing functional module also extracts the PCR information in the code stream simultaneously, is used for clock recovery.Audio frequency PES stream through the simulated audio signal of maximum six sound channels of output after the conversion of audio frequency digital to analog conversion module, or is directly exported the SPDIF light signal by the PCM signal of audio decoder decode output audio; Video PES stream is unpacked into video ES stream through the PES analyzer, after the processing through Video Decoder and blender under the cooperation of memory, again by output analog video YPbPr of the video digital to analog conversion mould in its sheet or rgb video component signal.
The utility model is with a Serial Port Line two set-top box to be coupled together, and by the menu mutual interface, selects to carry out software data transmission or program data transmission.After primary set-top box had been selected, power-off restarting carried out the transmission of obtaining of data from set-top box by starting the LOADER program.The serial ports that at first can carry out two set-top box connects communication, after the communication successful connection, pass through the address, read the data of primary set-top box, read 1024 bytes at every turn, these data are put in the array, carry out 1024 data add up a check value, also be deposited in the array, can data send to serial ports to these a string totally 1025 bytes this moment, and slave reads this 1025 data, identical preceding 1024 data of reading income value that also adds up with last data that gets access to, it is errorless to illustrate that then data transmit, and receives the data success, and this moment, slave was written to corresponding address block to the data of this 1K again.Income value is different with last data that gets access to if add up, and illustrates that then transfer of data is wrong, postbacks order and gives main frame, allows main frame retransmit this string data, if continuous 5 times are all transmitted failure, and then upgrading failure.Repeat this string read operation, finish up to data read is erasable, upgrade successfully.
Set-top box of the present utility model not only can be upgraded by computer instrument or OTA, can also realize two transfer of data between loom, not limited by tool equipment, as long as can realize the upgrade job of set-top box by two looms.
