Abstract

The utility model provides an IGRS device which comprises a multimedia device and an IGRS module. The multimedia device comprises a multimedia decoding chip and a first interface connected with the multimedia decoding chip; the IGRS module comprises a microcontroller main control chip, a network card and a second interface; one end of the microcontroller is connected with the network card and the other end is connected with the second interface; the first interface is connected with the second interface. The IGRS device has the advantages that the special high performance DSP decoder in the digital media adapter is avoided; the operation of the DSP decoder is transferred to the embedded media processing chip in the digital television; meanwhile, the IGRS module is added to the IGRS device so that the multimedia decoding and the network processing are separated into two parts through the hardware; not only the production cost of the digital media adaptor is reduced, but also the multimedia device such as the digital television is enabled to support the IGRS function.

Description

IGRS's device

Technical field

The utility model belongs to the digital home field, relates in particular to a kind of IGRS device.

Background technology

(the IGRS of IGRS, Intelligent Grouping and Resource Sharing) DMA (DMA), mainly be responsible in following the digital home network of IGRS protocol, preparing streamed multimedia content, broadcast in home entertainment device, reception, decoding and playback comprise the Media Stream of compressed video, audio file and rest image, simply say to be exactly people user's multimedia processing platform one by one.The DMA scheme of main flow has one 32 master cpu (MCU) usually on the market at present; the High Performance DSP decoder of a special use; built-in Ethernet card or external wireless interface module, software scenario add the DMA application software based on real-time embedded OS (Linux or Wince) usually.The DMA of this type owing to embed special-purpose High Performance DSP decoder, makes that its cost is higher.

Meanwhile, the appearance of functions such as the local broadcast of USB, recordable TV set makes that Digital Television has begun built-in medium codec chip is equipped with as built-in standard.The multimedia processing capability of the media decodes chip in the Digital Television is very powerful, but Digital Television but lacks the support to network function.

Therefore, in following the digital home network of IGRS protocol, how in the manufacturing cost that reduces DMA, make multimedia device such as Digital Television can support that IGRS's function is the problem of the current digital home required solution in field.

The utility model content

The purpose of this utility model is to provide a kind of IGRS device, is intended to solve the manufacturing cost that can't reduce DMA that exists in the prior art, and makes multimedia devices such as Digital Television can support IGRS's function.

The utility model provides a kind of IGRS device, comprising: multimedia device, described multimedia device comprise multimedia decoding chip and first interface that is connected described multimedia decoding chip; And IGRS's module, described IGRS module comprises microcontroller main control chip, network interface card and second interface, and an end of described microcontroller main control chip connects network interface card, and the other end connects second interface, and described first interface is connected with described second interface.

Technical solution adopted in the utility model also comprises: described first interface and second interface are USB interface or fire-wire interfaces.

Technical solution adopted in the utility model also comprises: described multimedia device is a television set.

Technical solution adopted in the utility model also comprises: described microcontroller main control chip is the ARMMCU main control chip.

Technical solution adopted in the utility model also comprises: described network interface card is Ethernet card or WLAN (wireless local area network) network interface card.

The technical solution of the utility model has following advantage or beneficial effect: IGRS of the present utility model device has saved the dedicated high performance DSP decoder in the DMA, the work of DSP decoder is transferred to built-in media processing chip in the Digital Television, add IGRS's module simultaneously, multimedia decoding and network processes are divided into two parts from hardware, not only reduce the manufacturing cost of DMA, and made multimedia devices such as Digital Television can support IGRS's function.

Description of drawings

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.

See also Fig. 1, be the structural representation of IGRS of the present utility model device.IGRS of the present utility model device comprises multimedia device 10 and IGRS's module 20.In the present embodiment, this multimedia device 10 is a digital television, and it comprises media decodes chip 11 and first interface 12 that is connected with media decodes chip 11.This IGRS's module 20 comprises microcontroller main control chip 21, network interface card 22 and second interface 23.Network interface card 22 connects an end of microcontroller main control chip 21, and microcontroller main control chip 21 other ends connect second interface 23.Be specially, microcontroller main control chip 21 is by attribute interface (not drawing among the figure) to be set to be connected with network interface card 22.The transmission of the mutual and multi-medium data that this IGRS's module 20 interconnects by the network interface card 22 and the outside network equipment, the transmission of the mutual and multi-medium data that operation (SuSE) Linux OS and IGRS's application software on the microcontroller main control chip 21, IGRS's application software interconnect by the network interface card 22 and the outside network equipment.This IGRS's module 20 does not have multimedia processing capability, that is to say that it only just moves the control protocol of IGRS, and receive multi-medium data of coming by the outer transmission of band (the outer transmission of band is that data information transmission is utilized independently carrier channel), so just greatly simplify complexity that the system module of DMA designs and reduced cost.After receiving multi-medium data, microcontroller main control chip 21 is directly delivered to second interface 23 with data and is exported first interface 12 of multimedia device 10 to.The input of first interface 12 by multimedia device 10, multimedia decoding chip 11 receiving multimedia datas that multimedia device 10 is built-in also begin decoding, its processing mode and read media file on the USB peripheral hardware (as hard disk) and codec class like (even may be identical) by first interface 12.In execution mode of the present utility model, first interface 12 and second interface 23 can be USB interface, also can be fire-wire interfaces (IEEE 1394); Network interface card 22 can be an Ethernet card, also can be the WLAN (wireless local area network) network interface card; Microcontroller main control chip 21 is ARMMCU main control chips.

Execution mode of the present utility model, for digital television, if an external USB memory device, TV can be play-overed the media file on the USB memory device so; If external IGRS's module so just can be play-overed the media file on the outside network device.

IGRS of the present utility model all-in-one principle can also apply to computer, mobile phone etc. to be possessed on other multimedia device of multimedia decoding chip.

IGRS of the present utility model device has saved the dedicated high performance DSP decoder in the DMA, the work of DSP decoder is transferred to built-in media processing chip in the Digital Television, add IGRS's module simultaneously, multimedia decoding and network processes are divided into two parts from hardware, not only reduce the manufacturing cost of DMA, and made multimedia devices such as Digital Television can support IGRS's function.
