The utility model comprises a DVB receiver, a display system, a voice system, a control system and a signal switch system, characterized in also composed of a multimedia processing system, a memory device interface and a network interface, wherein the memory device interface and the network interface are connected with the multimedia processing system, the output of the multimedia processing system is connected with the signal switch device, and the multimedia processing system is connected with the control system. The utility model has the advantages that the utility model can receive TV signal and support network connection and being read by memory device, with stable operation and high property/value ratio.
Description
Technical field
The utility model relates to TV tech, particularly a kind of multitask IDTV system.
Background technology
Along with the development of TV tech, the television set of a kind of IDTV of being called has appearred, Integrated Digital TV, promptly integrated digital television both at home and abroad.IDTV on the common meaning generally integrates digital television broadcasting (DVB) receiving unit and general television set, makes it have the function that receives DVB.Because the standard of domestic DVB-T also do not determine, this IDTV universal run into very big resistance.Simultaneously along with digital encoding and decoding compress technique and rapid network development, the appearance of IDTV is used with service a new generation that is different from common TV becomes possibility, and these new application will have very big enhancing with service than present simulation or simple digital television broadcasting system on function.
Existing IDTV is generally by the DVB receiving system, display system, and audio system, several parts such as control system and signal switching apparatus constitute.Among the existing IDTV, have plenty of utilization x86 platform, have plenty of and adopt the chip of function singleness to realize, can not satisfy the demand that network connects and external storage medium reads.
The utility model content
Technical problem to be solved in the utility model, be exactly simple at existing IDTV function, can not carry out network and connect the shortcoming that is connected with external storage medium, provide a kind of can receiving digital television broadcast, can connect the integrated digital television of multitask that is connected with exterior storage medium by network again.
The utility model solve the technical problem, and the technical scheme of employing is that the integrated digital television of multitask comprises DVB receiving system, display system, audio system, control system and signal switching apparatus; It is characterized in that, also comprise multimedia processing system, memory device interface and network interface; Described memory device interface is connected with described multimedia processing system with network interface, and described multimedia processing system output is connected with signal switching apparatus, and described multimedia processing system is connected with described control system.
The beneficial effects of the utility model are, can received television signal, again can network enabled connect, the storage medium read functions.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure chart of multimedia processing system.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The technical solution of the utility model combines IDTV with the multimedia decoding technology, constitute the integrated digital television of multitask with card-reading function, network media playing function and DVB receiving function.In the place that the DVB technology is not popularized as yet fully, be a kind of have practical significance and prospective product.
As shown in Figure 1, the integrated television set of multitask digitlization of the present utility model comprises the DVB receiving system, display system, audio system, control system and signal switching apparatus, multimedia processing system, memory device interface and network interface.Memory device interface comprises the SD card that is used to connect SD FLASH storage medium, the CF card that is used for connecting CF FLASH storage medium, is used for connecting the USB interface of USB flash memory disk storage medium, and the hard-disk interface that is used for connecting hard disk; Network interface is used to connect network, receives the Streaming Media on the network.Multimedia processing system is finished the multi-media signal decoding processing, and to the signal switching apparatus output signal, is selected to play by signal switching apparatus.The CPU of multimedia processing system is connected with control system, by the work of control system united and coordinating complete machine.
In the utility model, concrete video display system can be CRT display unit, LCD display unit or PDP display unit.
Embodiment
Fig. 2 shows the structure of this routine multimedia processing system.
Among the figure, the core circuit of multimedia processing system is that model is the MIPS chip of PNX8550, mainly real-time multi-task is coordinated and is handled, and operation system of software adopts the LINUX embedded OS.The function of each several part is described respectively below.
DSP and peripheral part comprise the PNX8550 chip, 128MDDR memory, 64MFLASH memory and buffer memory (model is 74244/245).PNX8550 is responsible for that operating system, driver, task management, network processes, electronic program guides are handled, the decoding of audio frequency and video, LCD control etc.; Start-up routine, application program leave in the continuous FLASH memory by buffering; The DDR memory that is attached thereto then is the storage place of temporary transient data in the program operation process.
Network portion comprises RJ45 interface/transformer, network control chip DP83816.This part is the passage of this machine and Internet exchange message, in order to realize signal transmission, reception and the relevant treatment of this machine and Internet.
With the PNX8510 chip is the audio/video encoding/decoding part of core, and the digital video signal that PNX8550 is sent carries out the coding of TV signal, simulation CVBS signal, y/c signal and the YCbCr signal of output PAL/NTSC standard; Digital audio and video signals to the digital audio interface input carries out the D/A conversion, and the stereo audio signal (Audio) of output simulation also can pass through digital audio interface outputting digital audio signal as required
The chip TCM811 that resets provides reset signal for PNX8550.
CPU finishes the coordination with control system, and assists to finish the multimedia Processing tasks.
