Abstract
The utility model provides a digital set-top box, comprising a radio-frequency input interface, a high-frequency head and a digital set-top box main chip which are connected in series, wherein the digital set-top box main chip is also connected with a code stream output module which is provided with an Ethernet interface. Therefore, the digital set-top box can become a digital signal acquisition and analysis terminal; the cost investment of code stream analysis is low; in the code stream analysis work, the code stream analysis can be carried out by only needing to carry a notebook computer to be connected with a digital set-top box; and the carry is convenient.
Description
Technical field
The utility model relates to a kind of top box of digital machine, relates in particular to a kind of top box of digital machine of gathering with the assistant analysis code stream.
Background technology
In the digital TV network test, often need use the code stream analysis instrument.The code stream analysis instrument can insert and carry out channel-decoding in the digital TV network, is decoded into after the data flow bit stream data is analyzed and display result, is the equipment of digital television signal being gathered the data analysis of decoding and digital TV field specialty.
This code stream analysis instrument is as a kind of test analysis equipment of specialty, and development cost is higher, and demand is less relatively, so price comparison is high.If the code stream analysis instrument is equipped with special display module, then cost is higher; As not being equipped with, general other the needs connects computer, and corresponding software is installed, as showing and other input/output terminal.
Digital television business has goed deep into huge numbers of families at present, and most of family all installs digital TV set-top box or other digital TV terminal equipment, runs into various abnormal conditions unavoidably, needs to carry out the context code current test to each family.Just need to be equipped with the code stream analysis instrument when going the test of user's family, in particular cases, concerning digital-TV operator, need to be equipped with a lot of code stream analysis instruments, cost is very high.In addition, code stream analysis instrument volume is too heavy, carries also inconvenience, perhaps needs to carry in addition notebook computer.
Summary of the invention
Goal of the invention of the present utility model provides a kind of top box of digital machine, and it can gather signal bit stream, and assists input signal is carried out code stream analysis.
The utility model realizes that the technical scheme that the foregoing invention purpose is adopted is, a kind of top box of digital machine, comprise the rf input interface, tuner and the top box of digital machine master chip that are linked in sequence, it is characterized in that, described top box of digital machine master chip also is connected with a code stream output module, and described code stream output module is provided with an Ethernet interface.
After adopting such scheme, digital TV set-top box becomes a digital signal processing and analysis terminal, and can realize large-scale mass production, and the market price of a top box of digital machine has only hundreds of unit.This code stream analysis solution does not need to add any hardware in addition, under the site environment of existing digit set-top box, does not have other cost input.In code stream analysis, only need carry a notebook and be connected with top box of digital machine, can carry out code stream analysis, easy to carry.
Description of drawings
Fig. 1 is the structured flowchart of the top box of digital machine of the utility model embodiment.
Embodiment
Embodiment: referring to accompanying drawing, the top box of digital machine of present embodiment comprises the rf input interface, tuner and the top box of digital machine master chip that connect in regular turn, and the top box of digital machine master chip also is provided with a bypass, it is connected to an Ethernet interface by a code stream output module, connects for PC.
The code stream output module that increases in the top box of digital machine, the digital television code stream that tuner can be resolved export the Ethernet interface of top box of digital machine in real time to;
After PC connects the top box of digital machine Ethernet interface, can be by the code stream analysis software in the PC, to real-time bit stream data analysis, the parsing of top box of digital machine output.
PC can also be provided with code stream extracting and filtercondition or the like by code stream analysis software to top box of digital machine transmit operation order.
