Abstract
The utility model relates to a web television, which comprises a line field drive circuit, a RGB combiner circuit 6 which consists of a chip TDA4780, and a television body provided with a video amplifying board and a display. The utility model is characterized in that the web television also comprises a network module and a RGB switching circuit, thereby achieving that the RGB signal and the line field signal which are outputted by the network module selectively switch over with the VGA signal which is inputted from the outside of the television. The selection switched RGB and the line field signal are sent to the interface of the VGA of the television. The RGB and the line field signal are inputted by the video board VGA of the television to accept the usual video signal processing. The utility model has the advantages that the design is simple, the performance-price ratio is high, the fuzzy image caused by using a set-top box is effectively overcame, and the utility model is the novel web television.
Description
The utility model relates to a kind of a kind of Web TV of information household appliances series products.
Conventional television is not Internet enabled, because its field frequency is 50Hz, so during by various set-top box online, the image of demonstration and literal shake are unintelligible.
The objective of the invention is to overcome the deficiencies in the prior art, a kind of Web TV is provided.Can be in online with the clear Internet content of browsing of television set, to satisfy the demand of people to information.
The utility model is to implement like this: online of the present utility model is to insert by 56KMODEM and mixed-media network modules mixed-media, mixed-media network modules mixed-media through setting is handled output R, G, B signal and row field signal, custom-designed RGB commutation circuit is selected the VGA of outside input and the rgb signal of mixed-media network modules mixed-media signalling channel to switch, with row commutation circuit row field signal being carried out four again selects behind two gatings to be connected with the RGB combiner circuit again and puts plate and be connected with having to look, the control signal of above-mentioned gating is the master control pin of existing TV host CPU, voltage stabilizing circuit output stable DC 5v voltage is given mixed-media network modules mixed-media when output low level, make it be in operate as normal, a RGB combiner circuit and a row commutation circuit be gating network module path also.
Further specify the utility model below in conjunction with drawings and Examples.
Fig. 1 general structure block diagram of the present utility model.
Fig. 2 web displaying circuit theory diagrams of the present utility model.
The utility model has and comprises a row drive circuit 4, RGB combiner circuit 6 with chip TDA4780 formation, video amplifier circuit or look is put the television set main body of plate 7 and display 8, it is characterized in that it is provided with a mixed-media network modules mixed-media 1, a row commutation circuit 3 and RGB commutation circuit 5, and RGB commutation circuit 5, a row commutation circuit 4 and mixed-media network modules mixed-media 1 are by connector N
2, N
3Link to each other, select to switch with the rgb signal of realization mixed-media network modules mixed-media output and the VGA signal of row field signal and the outside input of TV.Above-mentioned mixed-media network modules mixed-media 1 is that model is the integrated circuit of esee2.0.Mainly contain rgb signal, row field signal from the signal of mixed-media network modules mixed-media 1 output.Mixed-media network modules mixed-media 1 required 5V power supply is provided by TV set power, and resetting of mixed-media network modules mixed-media 1 controlled by the television set host CPU.Commutation circuit also receives the remote signal of mixed-media network modules mixed-media 1 output except carrying out RGB and row switch, and the remote control that this remote signal is delivered to television set is received head.The rgb signal of the rgb signal of mixed-media network modules mixed-media 1 and outside VGA9 input is respectively through three resistance (R

1) RC network that is in series is input to 3,5,7 and 1,4,6 pin of the TEA5114 of integrated circuit.And the rgb signal that has switched from its 11,13,16 pin output.The required row field signal of mixed-media network modules mixed-media 1 is input to integrated circuit BU4053 (N then respectively through emitter follower V1, a V2
8) 1,3 pin, the row field signal of external VGA input is input to 2,5 pin of said integrated circuit, the row field signal after switching from the output of the 15th, the 4th pin, 9,10,11 of integrated circuit BU4053 is that control pin is controlled by the television set host CPU.And, should make integrated circuit TEA5114 (N technically
7) and the control level of BU4053 just the same, to have guaranteed the synchronous switching of RGB and row field signal.10,11,12 pin of the chip TDA4780 of the RGB combiner circuit 6 that RGB after process is selected to switch and row field signal are delivered to existing TV together, row field signal is to the output pin interface of integrated circuit WT0841, and (not marking among the figure) put vision signal that plate 7, display 8 carry out common TV by looking of television set and handled and show.
Custom-designed online circuit design of the present utility model is simple, and the cost performance height has overcome visual unintelligible with set-top box online effectively, is a kind of new network television set.
