DETAILED DESCRIPTION OF THE INVENTION The present invention will be further described below in conjunction with the drawings and specific embodiments. Figure 1 shows a schematic diagram of a personal network service system. The personal network device and the personal network gateway form a personal network or a personal office i or network by means of a close-range link. The personal network gateway can be a mobile communication terminal, or a wired gateway (such as a computer, a digital home gateway, a set top box, etc.) having an external network access capability. The personal network device accesses the service provider such as the service server or the application/content server through the personal network gateway to obtain the corresponding service content. The present invention contemplates how to effectively utilize the transmission bandwidth resources between the service provider and the personal network gateway when the personal network device simultaneously acquires one service content. For example, when the personal network devices A, B, and C all download the same video program, the present invention fully utilizes the capabilities of each device in the personal network to achieve this demand. Generally, the personal network device A, B, and C actively initiate a service request for downloading a video program (if the personal network gateway itself requests the service, it can also be regarded as a personal network device), and the personal network gateway directly forwards these service requests to the service provider. The service provider respectively adapts the appropriate content according to the capabilities of different personal network devices to the personal network gateway, and the personal network gateway distributes the information to each personal network device. For example, if the screen sizes of the personal network devices A, B, and C are different, then the content sent by the service provider is different in image size. But we can think that this is just a different version of the same business content. The idea of the present invention is that when different personal network devices simultaneously initiate service requests for the same service content, the personal network gateway does not directly forward the service requests, but only sends one service request, and sends a version to the service provider. Business content can be used to improve the efficiency of transmission bandwidth. The personal network gateway ^ ¹ business content of this version is directly distributed to the corresponding personal network device or content conversion and distributed to the corresponding personal network device. The service content of this version is one of the personal network devices directly adapted to multiple request services, that is, the service provider only needs to adapt the device parameters of one of the representative devices. This selection process of representative parameters can be performed by the personal network gateway or by the service provider. The gateway of the personal network may be a mobile communication terminal. 2 is a flow chart of a method for a personal network device to acquire business content according to a first embodiment of the present invention. The following steps are included: Step S20: The personal network device sends the device parameters (screen size, content format, and the like) of the device to the personal network gateway. In this step, if the device in the personal network needs to obtain the service content, the device parameters of the device (such as screen resolution, supported content format, CPU processing capability, operating system, operating environment, etc.) are sent to the personal network. Gateway. The device parameter refers to the necessary parameters for the service provider to perform content adaptation, such as screen size, resolution, content format, device processing capability, operating system, and operating environment. Here, the personal network gateway is a device that accesses the external network, such as a mobile communication terminal, a home gateway, a set top box, and the like. Step S22: The personal network gateway sends the device parameters of the multiple personal network devices to the service provider. In order to obtain the service content adapted to the capabilities of the personal network device, the device parameters are sent to the remote service provider through the personal network gateway, such as a service server or an application/content server or other device providing the service content. Step S24: The service provider selects one representative parameter from the plurality of device parameters, and sends a content adapted to the parameter to the personal network gateway. Here, one representative parameter is selected from a plurality of device parameters, and the requirement is that the content adapted according to the parameter satisfies the requirement of the device with the highest performance among the personal network devices requesting the service, and/or the content adapted according to the parameter passes through After the content is converted, the remaining personal network devices that request the service can be adapted. Therefore, the service provider only sends one version of the content to save bandwidth, and the content can be directly adapted to a certain device of the above personal network device (assumed to be device A). Further, the content can be converted and adapted to other devices. Personal network equipment. In another embodiment, the selection of the representative parameter is performed according to the minimum requirement that the content of the parameter adaptation meets the capability of the personal network device, and the content adapted according to the device parameter can achieve the minimum bandwidth occupation in the transmission. Or the choice of representative parameters is to select device parameters with equalization capabilities in these devices. In another embodiment, if the personal network gateway has selected a suitable parameter (assumed to be the parameter of device A) in step S22, only the parameter is sent to the service provider. Then In step S24, the service provider does not need to select the parameter, and only needs to adapt the content according to a parameter sent by the personal network gateway to the personal network gateway. Step S26: After receiving the content, the personal network gateway distributes the content to the corresponding personal network device or performs content conversion and distributes the content to the personal network device. For example, if the representative parameter selected in the above step S24 is the parameter of the device A, the content received by the personal network gateway can be directly transmitted to the device A. Then, according to the parameters of the remaining devices, the appropriate content conversion is performed and then sent to the corresponding device. If the representative parameter selected in the above step S24 is performed according to the minimum requirement that the content adapted by the parameter satisfies the capability of the personal network device. Then the version of the business content can be directly used in all the personal network devices requesting the service, and the conversion process can be omitted. Or in other embodiments the unconverted business content may not be executed if it is available in other devices. In other embodiments, the conversion work can be done by other devices without requiring the personal network gateway to complete. For example, when the personal network gateway sends the content to the personal network device A, the parameters of the remaining other devices are also sent to the device A; the device A converts the received content according to the parameters of other devices, and then distributes the content to the corresponding device through the personal network. . Obviously, device A is required to have content conversion capability, and content conversion module is required in device A. Of course, device A also forwards the converted content to the personal network gateway first, and then distributes it to the corresponding device by the personal network gateway. Since the functions of different personal network devices in the personal network are different, the purpose of the present invention can be accomplished by using different combinations of functions. The content conversion here refers to processing the current version of the business content received by the personal network gateway and converting it into other versions of the business content that can be adapted to other devices. For example, image resolution of video/image content, sample rate or rate adjustment of audio content, file format adjustment, text encoding adjustment (such as Simplified Chinese character conversion), and so on. 3 is a flow chart of a method for a personal network device to acquire business content according to a second embodiment of the present invention. The process is similar to the process in FIG. 2. First, in step S30, the personal network device transmits the device parameters to the personal network gateway. The difference is that, in step S32, a representative parameter is selected from the device parameters of the plurality of personal network devices by the personal network gateway, and the parameter is sent to the service provider. In this case, in step S34, the service provider does not need to select, and only needs to send the service content adapted to the received parameters to the personal network gateway, and then step S36 is the same as step S26, that is, the personal network gateway receives the above. After the content is distributed to the corresponding device through the personal network or the received content is converted and distributed to the corresponding device. In addition, after the step of transmitting, to the gateway of the local area network, a version of the service content that is adapted to the device parameter of one of the device parameters of the plurality of network devices requesting the same service content, the method may further include The comparing step compares whether multiple network devices requesting the same service content are suitable for the same version of the service content, and if yes, directly provides the version of the service content to the plurality of network devices requesting the same service content. 4 is a block diagram of an apparatus in accordance with an embodiment of the present invention.
