In this embodiment, the media address is stored in the memory 2〇4 in a manner of a comparison table 6.1 (see FIG. 9). The media address determining module 2032 is configured to determine whether the roaming occurs according to the received packet, that is, according to the comparison between the received packet signal strength and the preset value_intensity, thereby determining the remote control device 201. s position. In detail, the strength of the packet signal is lower than the preset value for a period of time (a few seconds to a few minutes), or the remote control device 201 does not receive the signal in the network, and then the remote control device (ie, the user) is determined to leave. The area. On the other hand, if the strength of the packet signal is higher than the preset value for a certain period of time, it is determined that the remote control device 201 enters the new area or is in the original area. In this embodiment, the preset value is a threshold in decibels. The first switch module 2034 is configured to send a close proximity or _off command. The query module 2035 is configured to query the media message according to the location of the remote control device 201. That is, the message of the first media player 301 or the second media player 4〇1 is queried. In the first wireless local area network module 202, the second obtaining module 2〇21 also receives a packet, and obtains a media message from the packet, where the received packet and the packet received by the first obtaining module 2031 are received. The difference is that the packet is a packet that is transmitted through a universal plug and play. The media message acquired in this embodiment includes the unique device name of the media device and the interrupt message. The parsing module 2022 15 200814553 is configured to parse the media information acquired by the second acquiring 4 n〇1, modulo, and 2021, process it, and store it in the storage device 204. Among them, the unique device name is in the comparison table 601 (see Figure 9) or the left side. The second storage module 2024 is used to send a remote open or close command. The transmission control module 2 is slightly used to transmit a control command 'storing a media player interrupt message' according to the location of the remote device tearing and to control another media player to automatically play from the media interruption according to the "interrupt. fL heart." The group 2026 includes an IEEE 802.1 communication interface. • In the present embodiment, when the remote control device 201 is roaming, the transfer control module 2026 transmits a control command to the first media player 3〇1, stores the interrupt message, and transmits the control command. To the second media player 4〇1, the second media player 401 is controlled to automatically play from the interruption. FIG. 3 shows the wireless home network system remote control device 2〇1, the first media playing state 301, and the second. A transmission flow chart between the media player 4〇1 and the media server 5〇1. First, the remote control device 2〇 multicasts a single message to all media devices in the network to find related media. The device or the service. In the embodiment, the discovery message is transmitted in a format of a packet, where the discovery message includes a specific message or a service message. For example, type, identifier, etc. All media devices in the network listen to the discovery message, and the matched media devices, such as the first media player 301, the second media player 401, and the media server 501 respectively respond to the discovery message. And transmitting a response message to the remote control device 201. The remote control device 201 establishes a comparison table 601 according to the content of the response message. In the present embodiment, the 'comparison table 601 is established in a dynamic manner. That is, the remote control unit 201 transmits the discovery message in real time. The media device in the network is updated, and the comparison table 6〇1 stored in the storage device 2〇4 is updated through the content of the response message. When the content of the response message is used, the media device in the network can also be determined in real time. The Ηττρ transmitted through the media server 501 is streamed to the first media player 301, and the user can view the entertainment content in the first area 30 by the first media player 301. 'π _ t user carries the remote control device 201 After leaving the first area 3, the remote control device 201 transmits a read and store command to the first media player 3〇1, and stores the interrupt message of the first media player 301. The interrupt message is stored in the memory 204 of the remote control device 2. At this time, if the user needs to close the first media player 301 'the remote control device 201 transmits a stop command to the first media player to stop playing, Then, the remote control device 201 transmits a close command to the first media player 301 to close the first media player 301. In this embodiment, whether the user needs to close the first media player 301 is when the user leaves the first area 3 Previously, the option to stop and close is selected while the autoplay function option is activated. These options are provided by the activation module 205 of the remote control device 201. When the user roams to the second area 40, the remote control device 201 transmits an open command to the first The second media player 401, causing it to turn on, then transmits a play command to the second media player 401 for playback. The opening command is sent by the switch module 2034 of the first network personal area module 203. In addition, the second media player transmits an HTTP request to the media server 501 to find a corresponding category of entertainment, such as video on demand, MP3, picture or video broadcast. Thereafter, the remote control device 201 transmits a seek command to the second media player 4〇1, wherein the seek command includes an interrupt message stored in the first media player 301 of the remote control device 201. After the second media player 4〇1 reads the interrupt information, it transmits an HTTP lookup request to the media server 5〇1 to inform the interrupt location. Wherein, there is a block in the HTTP request as a range block. If the entertainment content is a video on demand, an MP3 or a picture, the field informs the media server that the interrupt position is 5〇1; The blocker informs the channel message. Therefore, the media server 501 transfers the HTTP stream from the interruption to the second media player 4〇1. In the wireless home network of the plug-and-play audio video architecture, the first media player 301 or the first media player 401 continuously sends an HTTP request to the media server, requesting the media server 501 to transmit the entertainment content. . Similarly, the media server 501 also continuously sends an HTTP stream response to the request. The media player that receives the HTTP stream will also send a reply message to the _ HTTP stream (not shown in the figure). FIG. 4 is a flow chart showing a method for automatically switching a wireless home network in an embodiment of the present invention. In step S101, the remote control device 201 receives a packet. In step S102, the remote control device 201 determines whether it has traveled based on the received packet, that is, whether it is roaming from the first area 3 to the second area. If the remote control device 201 has not roamed, the process proceeds to step sl1, and the remote control device 201 continues to receive a packet. In step sl5, if the remote control device roams, the remote control device 2〇1 stores the interrupt message of the first media playback of the first series 3 18200814553 301 in the storage device 2〇4. In step sl9, the remote control device 201 automatically plays from the interruption based on the interrupt message. FIG. 5 is a detailed flowchart of step S101 in FIG. 4 of the present invention. In step S2011, the remote control device 〇1 multicasts a discovery message to all media devices in the network to find a media device of the specified service. In step S2013, the media device in the network listens to the discovery message, and the matching media device transmits a response message to the remote control device 201. In this embodiment, the matched media devices correspond to the first ® media player 301, the second media player 401, and the media server 5〇1. In step S2015, the remote control device 201 stores the unique device name of the media device and the media address. The unique device name of the media device is transmitted through the wireless local area network, and the media address is transmitted through the wireless personal area network. In the present embodiment, the remote control device 2〇1 is an active receiving packet. That is, the remote control device 201 first sends a discovery message to the media device on the network, and the _ media device on the network transmits a response message to the remote control device 2〇1. In other embodiments of the invention, the remote control device 201 can also passively receive the packet. That is, the media device on the network will periodically transmit the packet to the remote control device 2〇1, and inform the remote control device 2〇1 of the status of the media device. Moreover, the periodic time can be set by the user. When a new device is added to the network, the device will transmit a packet to the remote control device 201' to disclose its equipment and services. Similarly, when the device is removed from the network, the device also sends a claim packet to the remote control device 201 stating that the service contained in the device has expired. 19 200814553 Figure 6 is a detailed flow chart of Figure 4 of the present invention. In step S301, the remote control device 201 receives a packet. In step S303, the remote control device 201 determines whether the remote control device 201 has left the first area 30 based on the received packet. If the remote control device 201 has not left the first area 30, proceeding to step S301, the remote control device 201 continues to receive a packet. In step S305, if the remote control device 201 leaves the first area 30, the remote control device 201 stores the interrupt message of the first media player 301 in the storage 204. The interrupt message includes an interrupt location. In step S307, the remote control device 201 determines whether it has roamed to the second area 40. If the remote control device 201 does not roam to the second area 40, the remote control device 201 receives another packet (step S308), and repeats step S307 to continue to determine whether to roam to the second area 40. In step S309, the remote control device 201 automatically plays from the interruption based on the interrupt message. In this embodiment, in step S305, the remote control device 201 stores the interrupt message of the first media player 301 in the storage 204. The remote control device 201_ may store the interrupt message after leaving the first area 30, and may also leave the device. Save the interrupt message. In other embodiments of the present invention, the remote device 201 storing the interrupt message of the first media player 301 in the memory 204 may also be executed when the remote device 201 roams to the second region 40. Figure 7 is a detailed flow chart of Figure 6 of the present invention. At step S401, the remote control device 201 receives a packet. In step S4031, the remote control device 201 determines whether the strength is less than a preset value strength based on the received packet signal. If the strength of the 200814553 packet signal is not less than the preset strength, the remote control device 201 repeats step S401 to continue receiving a packet. In step S4033, if the strength of the packet signal is less than the preset value strength, it is determined that the remote control device 201 leaves the first region 30. When the remote control device 201 leaves the first area 30, step S405 is executed, and the remote control device 201 stores the interrupt message of the first media player 301. In step S406, the remote control device 201 determines whether the first media player 301 of the first area 30 is closed. In step S4061, if the first media player 301 of the first zone domain 30 is to be closed, the remote control device 201 stops the playback of the first media player 301. In step S4063, the remote control device 201 turns off the first media player 301. At step S408, the remote control device 201 receives another packet. If the first media player 301 of the first area 30 is not closed, the remote control device directly performs step S408 to receive another packet. In step S4071, the remote control device 201 determines whether the strength of the received packet signal is greater than a predetermined value strength. In this embodiment, the preset value is the same as the preset value of step _S4031. In other embodiments of the present invention, the preset value and the preset value of step S4031 may also be different values. That is, the preset value of step S4031 is the first preset value, the preset value of step S4071 is the second preset value, and the first preset value is smaller than the second preset value. If the strength of the packet signal is not greater than the preset strength, the remote control device 201 repeats step S408 to continue receiving another packet. In step S4073, if the strength of the packet signal is greater than the preset value strength, it is determined that the remote control device 2〇1 roams to the second region 40 of 21 200814553. When it is determined that the remote control device 201 roams to the second area 40, step S409 is executed, and the remote control device 201 automatically plays back from the interruption according to the interrupt message. FIG. 8 is a detailed flowchart of step S109 in FIG. 4 of the present invention. In step S5073, the remote control unit 201 roams to the second area 40. In step S5091, the remote control device 201 searches for the basic message of the second media player 4〇1 of the second area 40. In this embodiment, the remote control device 201 receives the message in the packet, that is, the media storage control address (MAC) or the device address (ie, 八 001 〇, in the comparison table of the storage device 204, The second media player 401 of the second area is 4. The remote control device 204 turns on the second media player 401 in step S5093. In step S5095, the remote control device 201 reads the first media player 301 from the storage 204. The message is interrupted and transmitted to the second media player 4〇 1. In step S5097, the second media player 401 is played by the interrupt.
