Preferably, described audio and video output interface is the HDMI interface.
Compared with prior art; advantage of the present utility model with good effect is: multimedia player of the present utility model adopts SATA USM interface to be connected communication with outside source; its data reading speed is far above traditional USB2.0 interface and SATA interface; support the high-speed transfer of high capacity high resolution audio and video file; and need not outside power supply separately; the complicacy of wiring reduces greatly, has the function of supporting hot plug and electrostatic protection simultaneously.
After reading the detailed description of the utility model embodiment in conjunction with the accompanying drawings, other characteristics of the present utility model and advantage will become clearer.
Description of drawings
Fig. 1 is the internal circuit principle schematic of a kind of embodiment of the multimedia player of the support SATA USM transmission that proposes of the utility model;
Fig. 2 is the structural drawing of SATA USM interface among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done explanation in further detail.
SATA USM is that the English of SATA Universal Storage Module is called for short, it is SATA common store module, it is a kind of new interface standard of the SATA-IO of SATA International Standards Organization exploitation, can support the data rate of maximum 6Gbps, and can the perfect compatible first generation (1.5Gbps) and the second generation (3Gbps) driver.
In order to adapt to the quick transmission requirement of large capacity audio video files such as present high-definition movie, the utility model proposes a kind of multimedia player of the SATA of support USM interface, elaborate the circuit establishment structure of described multimedia player and the definition mode of SATA USM interface below by a specific embodiment.
Embodiment one, present embodiment disposes SATA USM interface J1 on multimedia player, and adopt and support the multimedia chip N1 of SATA USM data transmission standard to carry out circuit design, referring to shown in Figure 1, specifically, can two couples of difference signal terminal SATA0_TX+, SATA0_TX-of data, the corresponding connection of respective pin SATA_HSIP, SATA_HSIN, SATA_HSON, SATA_HSOP that SATA0_RX-, SATA0_RX+ pass through capacitance C143 ~ C146 with the multimedia chip N1 of series connection respectively will be used to transmit among the SATA USM interface J1.Described capacitance C143 ~ C146 can play the purpose of bias voltage in the isolation signals in circuit.When pegging graft signal source equipments such as outside hard disk or computing machine by described SATA USM interface J1 when multimedia player, can carry out the high-speed transfer of data by described two pairs of difference signal terminal.Wherein, difference signal terminal SATA0_TX+, SATA0_TX-are used for transmission transmission data; Difference signal terminal SATA0_RX+, SATA0_RX-are used for transmission and receive data, adopt SATA USM transmission specification can support data rate up to 6Gbps, therefore, the data reading speed of multimedia player are had full guarantee.
