In the first wireless personal area network module 203, the first obtaining module % is configured to receive the packet 'gp' to receive the packet sent by the media player 3〇1 and the second media 1327831, and the player 401, and Get media messages from this packet. In this embodiment, the obtained media message includes address information of the first media player 301 and the second media player 401. The group bee corresponds to a media storage control address '(MAC), and the Bluetooth corresponds to a device address (BD_ADDR). In this embodiment, the media address is stored in the storage 204 in a manner of a comparison table 601 (see FIG. 9). The media address determining module 2032 is configured to determine, according to the received packet, whether the remote control device 201 is roaming, that is, to determine the location of the remote control device 201 according to the comparison between the received packet signal strength and the preset value. In detail, if the strength of the packet signal is lower than the preset value in 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, the remote control device 201 is determined. That is, the user) leaves 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 (dB). The first switch module 2034 is configured to transmit a close proximity or a close 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 401 is queried. In the first wireless local area network module 202, the second obtaining module 2021 also receives a packet and obtains a media message from the packet, wherein the received packet is different from the packet received by the first obtaining module 2031. The packet is a packet that is transmitted through a universal plug and play. In this embodiment, the obtained media message includes a unique device name of the media device and an interrupt message. The parsing module 2022 15 parses the media message acquired by the first acquisition module 2021, processes it, and stores the rest in the memory class. The unique device name is stored in the comparison table (see Figure 9). The second switch module 2024 is configured to send a remote open or close command. The transmission control module view 6 is configured to store an interruption message of a media player according to the position transmission-control command of the remote control device 2〇, and control another media player to automatically play from the media interruption according to the interruption message. The transfer control module 2026 includes an IEEE 802.11 communication interface. 1 In the present embodiment, when the remote control device 2〇1 roams, the transfer control group 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 play. The device 4〇1 controls the second media player 401 to automatically play from the interruption. 3 is a flow chart showing the transmission between the remote control device 2, the first media player 301, the second media player 401, and the media server 501 of the wireless home network system of the present invention. First, the remote control device 201 multicasts a message to all media devices in the network to find related media devices or services. In this embodiment, the discovery message is transmitted in a format of a packet. The discovery message includes some specific information of the device or a message of a service, such as a type, an identifier, and the like. All the 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 transmit a response message to the remote control device. 201. The remote control device 201 creates a lookup table 601 based on the contents of the response message. In the present embodiment, the lookup table 601 is established in a dynamic manner. That is, the remote 16 1327831 control device 201 sends the discovery message to the media device in the network in real time, and the inner valley of the message is sent to the comparison table 6() 1 stored in the storage 204 to further transmit the content of the response message. The real-time determining network (4) body device traverses the Ηττρ stream of the media word processor 501 to the first media player 301'. The user can use the media player to view the entertainment content in the first area. When the user carries the remote control device to leave the first area %, the remote control device 201 transmits and reads a command to the first media player 3〇, and stores the interrupt message of the first media player 301. The interrupt message is stored in the memory 204 plus the remote control. 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 3〇1 to stop playing, and then the remote control device 201 transmits a close command to the first media player. The 301 is configured to close the first media player 3〇1. In this embodiment, whether the user needs to close the first media player 301 is to select the stop and close option while the user leaves the first area 30 to start the automatic play function option. These options are provided by the activation module 205 of the remote control device 2〇1. When the user roams to the second area 40, the remote control device 201 transmits an open command to the second media player 401 to turn it on, and 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 entertainment device, such as a video on demand, u.,, - MP3, picture or video broadcast, after the remote control device 201 value for this person to recognize you to stay in a class. The brother finds the second media ', lA^3 7 匕 contains the interrupt message of the first media broadcast 3〇1 stored in the remote control device 201. After the media player 40! reads the interrupt message, the device transmits =- HTTP to find the request to the media server 5〇, to inform the interrupt location. In the HTTP request, there is a “placement for the range of the position. If the entertainment content is a video on demand, an MP3 or a picture, the copper position informs the media feeding device of the interruption position; ► if the entertainment content is a video broadcast The rotten position informs the channel message. Therefore, the media server 501 transmits a stream of Ηττρ from the interrupt to the second media player. In the wireless home network of the plug-and-play audio video architecture, the first media player 301 or the second media player 4〇1 is constantly sending an HTTP request to the media requesting the media. The server 5 〇 ι transfers the music content. Similarly, the media server 501 also continuously transmits the Ηττρ stream in response to the HTTP 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 Si〇; [, the remote control device 2〇1 receives a packet. In step S102', the remote control device 201 determines whether or not it has occurred based on the received packet, i.e., determines whether it roams from the first area % to the second area 40. If the remote control device 201 has not roamed, the execution of the small step S101 'the remote control device 201 continues to receive a packet. In step sl5, if the remote control device 201 is roaming, the remote control device 201 stores the interrupt message of the first media player 18 1327831 '301 of the first area 3 于 in the storage 204. In step si 〇 9, 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 201 multicasts a discovery message to all media devices in the network to find a media device of the designated service. In step S2013, the media device in the network listens to the discovery message. The matched media device transmits a response message to the remote control device 201. In this embodiment, the matched media device corresponds to the first > media player 301, the second media player 4〇1, 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 201 actively receives the 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 201. In other embodiments of the invention, the remote control device 2〇1 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 201 of the status of the media. 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 1327831 ‘ Figure 6 is a detailed flow chart of Figure 4 of the present invention.

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 according to 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, and may store the interrupt message after the remote device 201 leaves the first area 30, and may also leave the device while leaving. 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 packet 1327831 • packet signal is not less than the preset value strength, the remote control device 201 repeats the 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 the 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 201 roams to the second region 40° of 21 1327831 and determines that the remote control device 2〇1 roams to the second region 4〇, then the line is executed.
