Description

Signal source and television set with this signal source

Technical field

The television set that the utility model relates to a kind of signal source and has this signal source particularly relates to a kind of with the signal source of Kara OK function and the television set with this signal source.

Background technology

At present, the television set that mostly is the reception analog signal that is widely used, in the epoch that Digital Television arrives, be to pass through external equipment mostly, as, set-top box, DVD, DVB (Digital VideoBroadcasting, digital video broadcasting, a kind of Digital Television Open Standard of international recognition), digital signal is converted to exports to television set after the analog signal and show, for example, set-top box converts A/V (video standard signal) interface signal or Y to after digital signal is received, U, V interface signals such as (Analog Component Video signals), and the low display resolution analog signal after will changing exports to television set, as shown in Figure 1, television set is by the A/V port DVD player top box of plugging into respectively, the DVB set-top box, the Internet Protocol Television set-top box, but this kind framework, each set-top box all need independent current source that it is powered, simultaneously, each set-top box also needs independently remote controller respectively it to be controlled, and the signal of television set still simulates and this set-top box is exported to, the image that resolution is very low.Simultaneously because the external equipment kind is many, these equipment rooms have many resources to repeat, as: each machine is all wanted power supply, every equipment all needs a remote controller, each product all has the lead-out terminal that quantity does not wait, color is different, so just cause the aerial lug complexity, installed, use extremely inconvenient and take up space, used distinct device all need connect one time the end of a thread again.Simultaneously, also inconvenience preservation of a plurality of remote controllers, operation.The user increases a new equipment, must be complete machine, thereby the comprehensive use cost of user is higher, the no standard of each equipment output simultaneously, and like product interface, performance difference are big.

On the other hand, the high-end digital television of some costlinesses has the display mode of high-resolution (1080P, 1080i, 720P), and external equipment need connect with it by miscellaneous interface (VGA, DVI, HDMI etc.).Because the kind of interface of television set own is various, make outside auxiliary products, as: the output mode of set-top box is also of all kinds, and often the output signal of set-top box can't guarantee that also picture quality effect performance with high-end television sets is to ultimate attainment.

In the prior art, also have and to insert the composite type TV machine of television set in the TV set-top box.For example No. 200520115859.3 utility model patent of China discloses a kind of IP TV can be recorded in one machine, and it is built into the Internet Protocol Television set-top box in the LCD TV.Yet in the inside of combinations thereof formula television set, the Internet Protocol Television set-top box is to adopt different interface circuits to connect the movement circuit of television set.The standard of various interface and disunity do not have the expansion upgrade function yet, are difficult to increase new digital program reception sources.And different interface types has caused the existing system upgrading also relatively more difficult, the more important thing is that the scrambled TV service that can't adapt to different regions receives, and can't satisfy the different information flow requirement of possibility between each area, each operator.Because a certain specific function and main frame are made complete machine, destroyed the standardization of main frame, simultaneously, the specific function also not all client of possibility is needed.This type of type is generally the customization of a certain class particular client colony, is used for the specific occasion, but not popular demand, product can not be popularized in an all-round way.This class composite type TV machine is because the difference between the composite module causes product specification to differ, is difficult for realizing industry standardization that difficulty is carried out forming a complete production network of Related product in industry, so production cost is higher, auxiliary products are lack of standardization.

Along with the development of digitizing technique, at present, device interiors such as TV set-top box are handled all fully digitalizations and technical standard standard for the reading of audio frequency, vision signal, decompression etc.Digital audio/video standard interface HDMI at Digital Television popularizes in the whole world, like this, no longer needs to transmit analog signal between these equipment and Digital Television, and directly audio frequency, the video signal of transmission standard will be trends of the times.

Simultaneously, along with the pursuit of masses to spiritual amusement, the user wishes that the amusement function that realizes is more and more on television set, Kara OK function is wherein just arranged, and present most of Kara OK function can only be enough by means of player plays CD contents such as similar VCD, DVD, and player must have separate host and power supply independently, and not only use cost is higher, and also wastes resource.

In order to overcome the deficiencies in the prior art part, also in order to adapt to the constantly trend of development of digital television techniques, be necessary to provide a kind of and meet digital television standard, adaptive scope is wide, and the television set that economizes on resources and have the signal source of Kara OK function and have this signal source.
