Can use any Open Standard in the digital network to implement the present invention, for example Ethernet, MOST net, WLAN (wireless local area network) WLAN or IEEE1394.Yet, in the preferred enforcement described in this is used, used Open Standard MOST net (as previously described).Show based on the access point among the present invention of MOST net and the specific embodiment of gateway.Network transceivers 213 in each access point can use the commercial chip that obtains to implement, as the MOST network transceivers OS8104 that is produced by OASIS silicon systems inc.Core network management function in the MOST network is based on the automatic processing in distributed basis, and is embedded in the OS 8104 MOST transceivers.Since channel allocation, physical address assignments, error monitoring and power down/arouse all providing by chip, and the enforcement of network is just very simple, and can realize high-level network protection and reliability.Network Management Function is convenient in remote access, for example can be in the network diagnosis of each intranodal with the dispersing mode processing.
Like this, network 100 comprises the access point of arbitrary number, although only show access point 201,202,203,204,205 and 206.As shown in the figure, transceiver in all access points links to each other with serial mode mutually and has constituted network 100, Here it is based on the multimedia and the Control Network of ring topology structure, wherein all relevant Network Management Functions (for example allocated bandwidth and heavily distribution) all with distribution mode in inter-process.The control port of transceiver (CP) can be configured to the serial or parallel pattern in the network 100; Yet in this specific embodiment of the present invention, the control port of all transceivers in the network 100 all is configured to serial mode (I2C).The source port of transceiver (SP) also can be configured to the serial or parallel pattern.Yet for the number that makes the interface signal between access point and gateway minimizes, serial mode is preferred.Except network transceivers 213, each access point in the network 100 all comprises a microcontroller 214, and it links to each other via the control port of I2C bus 216 with transceiver 213.This microcontroller is also controlled user-indicating device 215, and this user-indicating device is placed in the front end of each access point and is used to user's indication network and connection status.This user-indicating device 215 can be implemented by using simple light-emitting section, LED or display.
As shown in the figure, via Tx gateway 207, transmitter 210 is coupled in access point 201, and by network 100, to receiver 211 and 212 broadcast figures or analog signal, this receiver 211 and 212 is coupled to access point 202 and 203 respectively via two Rx gateways 208.Before being inserted into network, need be adjusted to number format from the output of transmitter 210, this number format is access in some the source port of the network transceivers 213 in 201 and supports.As shown in the figure, this is adjusted in the Tx adjuster 217 and finishes, and another side is connected to the source port of the network transceivers in the access point on one side it is connected to the output of transmitter.When being inserted into network, controlled data can be captured by arbitrary access point in network 100, and it uses suitable R x gateway therein the data adjustment to be returned original form and is sent to receiver.In the drawings, be hunted down at access point 202 and 203, be adjusted back in the Rx adjuster 220 in Rx gateway 208, and sent to receiver 211,212 respectively from the data flow of the adjustment of transmitter 210.Tx and Rx adjuster in the gateway illustrate logic diagram as an example, and wherein via network 100, VCR301 and PC (image card) 302 sends simulation synthetic video/audio frequency and digital rgb data respectively simultaneously to television set 303 and PC monitor 304.As shown in FIG., at first be converted into number format among the ADC306 of simulation synthetic video/audio signal in Tx gateway 305 from VCR301, use as the MPEG2 algorithm to its compression and coding (in 307), to reduce required bandwidth then.The recipient, Rx gateway 309 is caught this and is come the compressed video/audio data of automatic network 100, and its decompression is become synthetic video/voice data with decoding (311), and these data are converted to simulation synthetic video/audio frequency then in DAC310, and are sent to television set 303.Because the output from image card 302 has been number format, the analog/digital conversion step in Tx gateway 305 is just optional.In order to reduce required bandwidth, before inserting network, still to use as jpeg algorithm and the RGB data be compressed and encode (308).Receiving a side, Rx gateway 312 catches the data of this compression of automatic network 100, and makes it turn back to the RGB data to its decompression and decoding, and is sent to PC monitor 304.
Except the adjuster part, in each gateway, no matter Tx or Rx comprise microcontroller and dual in line switch.When being coupled to access point, the microcontroller in each gateway is provided the visit via the transceiver of bus 216 in the access point.Preferably, the dual in line switch 222 in dual in line switch 219 in the Tx gateway and the Rx gateway 208 all is placed on the front end of each gateway, and can be disposed by the user.Tx gateway 207 and Rx gateway 208 have made up a gateway group.For each data flow is provided with a gateway group by network 100, it need be made up of a Tx gateway and one or several similar Rx gateway.All dual in line switchs in a gateway group all must equally dispose, thereby output same bits figure (bit pattern) is given the microcontroller in the gateway, and they combine with predefined bit figure to produce the unique group address at the gateway group there.This group address is used to via network 100 from the Tx gateway of coupling to the foundation of the data flow of the Rx gateway of all couplings, and this Rx gateway and Tx gateway belong to same gateway group.Predefine in the group address partly is a steady state value, be embedded in the application program in the microcontroller that runs in gateway group Tx and the Rx gateway, and relate to its relevant standard (for example synthetic video PALB or USB), and each standard of supporting is all had a unique figure.MOST network transceivers chip as mentioned above, OS8104 can be used to implement the interior transceiver 213 of access point.OS8104 supports 255 group addresss, and this means to have 255 transmitters to be coupled to network 100 simultaneously in theory.The arrangement of the 16 hyte addresses of being supported in OS8104 is illustrated.As shown in the figure, 8 variable parts in the group address can be divided into user definition and predefined part rightly.Yet, because high bandwidth can make use of the present invention very complicated for domestic consumer, so recommend to keep the bandwidth of user definition form low as far as possible.Allow definitions section address, User Part ground, and make it may connect several transmitters with identical characteristics and receiver (for example several VCR and television set) simultaneously to arrive network 100 and as required in groups it.The maximum number of similar transmitter of being coupled depends on the width of dual in line switch in the gateway.This is gone out by example, wherein VCR1, VCR2, VCR3, VCR4 and CD Player 1 have the Composite tone/vision signal of identical standard (for example PAL B, Composite tone accordingly) simultaneously respectively to TV 1, TV 2, TV 3, TV 4, TV 5 and high-fidelity 1 transmission via network 100.In this example, all gateways use 2 dual in line switchs to realize, transmit thereby there are 4 similar transmitters can be used for data simultaneously at most in network 100.
5 gateway groups can be divided into:
1, Tx gateway 501 and Rx gateway 502 and 503 (Composite tone/video);
2, Tx gateway 504 and Rx gateway 505 (Composite tone/video);
3, Tx gateway 506 and Rx gateway 507 (Composite tone/video);
4, Tx gateway 508 and Rx gateway 509 (Composite tone/video);
5, Tx gateway 510 and Rx gateway 511 (Composite tone).
Tx gateway 501,504,506 and 508 all similar and between them only difference be the value of their dual in line switch.Same Rx gateway 502,503,505,507 and 509 also is similar.As can be seen from the figure, the Rx gateway (for example Rx gateway 502 and 503) of several similar couplings may have identical dual in line switch value.Yet when pointing to similar Tx gateway, this is not have effectively.Two similar Tx gateways (it is coupled into network 100 simultaneously) do not have equal dual in line switch value.
With reference to the front, since in transceiver 213 be how to be provided with can mark needle to three kinds of states of each access point in the network 100:
1, default conditions:
In this state, there is not gateway to be connected to access point.By means of microcontroller 214 or power up or be connected when transceiver 213 is initialised when gateway and access point disconnect, access point enters this state.In this state, transceiver 213 or by network 100 remote accesses or by microcontroller 214 from this accessing.Network 100 is constantly used current updating network state transceiver 213, and microcontroller 214 periodically reads network state, for example from the available bandwidth of transceiver 213, and indicates this state to give the user by user-indicating device 215 is set.Access point 204,205 and 206 is in default conditions.
