Furthermore, the microprocessor is an ARM processer; and the data bus is an ARM control data bus. The utility model integrates a multimedia player with a digital television to provide a novel personal mobile digital terminal, thereby having the advantages of technique complementarity and content complementarity. In addition, the utility model not only receives the television programs, but also surfs the internet through an internally-arranged GPRS module.
Description
Technical field
The utility model relates to portable multimedia player (PMP/MP4).
Background technology
The MP4 world market just more and more receives an acclaim, and this MP4 is many to be memory with flash, cheap.But because the MP4 stored resource is limited, media content needs often to upgrade, and the general user can not often remove to download new video frequency program, so its practical efficiency is not high.On the basis of MP4, increase the demand that function of surfing the Net has then satisfied user's foreign exchanges, increase digital television function and satisfied the requirement that up-to-date video is arranged continually.
The maximum characteristics of terrestrial broadcasting Digital Television are to move to receive, and it is by ground TV broadcast cell site antenna emitting radio wave, and the user is the most basic transmission network form of digital television broadcasting by professional receiving equipment and television set TV reception.Except public good functions such as amusement, study, the generality of ground TV broadcast, controllability and survivability also are regarded as national security equipment, make it to become to mobilize its people's the most reliable the most direct information source under the state of emergency situation.And ground TV broadcast is from the transition of analog to digital, since its move reception, anti-interference, power is little, definition is high, acoustics is good, can be mutual etc. numerous advantages, caused the generally attention of the industrial quarters of national governments, China has also listed the timetable of progressively promoting.At present, wireless digital TV-set has been opened in national most of city.
But influence major obstacle that MP4 market increases fast at present and be and also few ofly on the market be the splendid contents of the PMP market development.Will seek out the approval of general marketplace in other words, at first must overcome a main obstacles now, promptly ordinary consumer whether can be at an easy rate obtains a large amount of splendid contents with very low-cost.Multimedia player is combined with Digital Television, is the technology imagination of a kind of technology complementation, a kind of content complementation especially.
The utility model content
For solving the problem that present player lacks Digital Television and online, the utility model provides a kind of personal mobile digital terminal, it combines the two function, not only has the ability that MP4 plays, and also has the reception and the GPRS function of surfing the Net of DMB-T Digital Television.
The utility model adopts following technical scheme:
A kind of personal mobile digital terminal, comprise: microprocessor, the display module that is connected with microprocessor, audio frequency processing circuit, the power module that is connected by data/address bus with microprocessor, the numeral tuner, and be connected in Digital Television source coding circuit between digital tuner and the microprocessor.
Further, also comprise the CA intelligent card interface that is connected by data/address bus with microprocessor.
Further, also comprise the memory card interface that is connected by data/address bus with microprocessor.
Further, also comprise the GPRS module that is connected by data/address bus with microprocessor.
Further, described microprocessor is an arm processor, and described data/address bus is an ARM control data bus.
Further, described microprocessor is the multimedia chip of MX32.
The utility model combines multimedia player with Digital Television, a kind of brand-new personal mobile digital terminal is provided, the advantage of its possess skills complementary and content complementation.It not only can receive TV, and can surf the Net by its built-in GPRS module.
