Abstract
The utility model relates to a digital multimedia technique, in particular to a digital multimedia receiving device. The utility model aims at overcoming the disadvantages that the current digital multimedia receiving device of multi-channel HDMI input needs a plurality of memories, and provides a digital multimedia receiving device of multi-channel HDMI input which can meet relevant requirements just with one memory. The technical proposal adopted by the digital multimedia receiving device is that the digital multimedia receiving device consists of a processor, a multi-channel HDMI interface, a switch of one out of multichoices , a multimedia signal processing part and a memory and the memory is connected with the HDMI interface through the switch of one out of multichoices r. The digital multimedia receiving device has the advantages that only one memory is needed to meet relevant requirements, thereby achieving the purpose of decreasing the memories and reducing cost.
Description
Technical field
The utility model relates to a kind of digital multimedia technology, particularly digital multimedia receiving apparatus.
Background technology
Develop rapidly along with current digital technology, most of digital multimedia receiving apparatus, comprise TV with video and Audio Processing part, or the stereo set etc. of Audio Processing part only arranged, all have HDMI (High DefinitionMultimedia) interface, and increasing digital multimedia receiving apparatus also has 2 tunnel, 3 tunnel even 4 road HDMI interfaces.In general, articulated an eeprom memory on the HDMI interface, EDID (ExtendedDisplay Identification Data) data have been preserved in the memory, comprise the title of multimedia receiver, the signal format that can show etc., when the HDMI transmitter is linked the HDMI receiving equipment, can read the digital signal of the form that receiving terminal can support by bus signals in the HDMI line.Multimedia receiver has several roads HDMI interface, just needs several eeprom memories, has increased product cost.
The utility model content
The purpose of this utility model is to overcome the shortcoming that the digital multimedia receiving apparatus that has multichannel HDMI input now needs a plurality of memories, the digital multimedia receiving apparatus that the band multichannel HDMI that provides memory of a kind of usefulness just can satisfy related needs imports
The utility model solve the technical problem, the technical scheme that adopts is that digital multimedia receiving apparatus comprises processor, multichannel HDMI interface, multiselect one switch, multimedia signal dispose part and memory, it is characterized in that described memory is connected with the HDMI interface by multiselect one switch.
The beneficial effects of the utility model are, a memory is connected with the HDMI interface by multiselect one switch, and only a memory of needs just can satisfy related needs, reaches the purpose of minimizing memory, has reduced cost.
Description of drawings
Fig. 1 is the pie graph of the Digital Television of existing multichannel HDMI input;
Fig. 2 is the pie graph of embodiment.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The utility model is connected by multiselect one switch an eeprom memory with the HDMI interface, reduced the quantity of eeprom memory, has reduced cost of manufacture.
Embodiment
This example is an example with the Digital Television with 3 road HDMI input, sets forth the technical solution of the utility model, concrete pie graph such as Fig. 2.
As Fig. 2, the Digital Television with 3 road HDMI input of this example comprises a three elections switch (as PS301), an eeprom memory, a processor, three HDMI interfaces, multimedia signal dispose part.Control signal is provided by processor, and this control signal can be the IIC signal of processor, also can be the I/O mouth of processor.When selecting the HDMI signal of a certain road input, processor sends control signal, the control three elections switch is selected correct HDMI input signal, links on the eeprom memory that has the EDID data after the bus signals in the HDMI line switches by selector switch partly to be connected with the multimedia signal dispose of television set again.
The Digital Television with 3 road HDMI input that is contrasted prior art as can be seen by Fig. 1 and Fig. 2 needs three eeprom memories just can satisfy related needs, and the utility model only needs 1 eeprom memory just can satisfy related needs.
The described technical scheme of present embodiment is equally applicable to panel TV, projection TV, CRT TV, LCD LCD TV etc.
Because each physical circuit in the technical solutions of the utility model all belongs to this area routine techniques, no longer describe in detail herein.Those of ordinary skill in the art according to foregoing description, can adopt various circuit to realize the technical solution of the utility model, and it all belongs to protection range of the present utility model.
