Abstract

The present document provides a method and apparatus for controlling digital living network alliance contents. One Media Access Control (MAC) recording unit is extended at the Digital Living Network Alliance (DLNA) device side for recording which MAC addresses are permitted to access or use the service of the DLNA device or prohibited from accessing or using the service of the DLNA device; one service control program is extended at the DLNA device side, and when there is another DLNA device transmitting a request to the DLNA device, the MAC address of the DLNA device is compared with the MAC address recorded by the MAC recording unit; and if the MAC address of the DLNA device is in the permission list or the MAC address of the DLNA device is not in the prohibition list, then the request will be permitted; otherwise the request will be rejected.

Claims

1. A method for controlling digital living network alliance contents, wherein, one Media Access Control (MAC) recording unit is extended at a Digital Living Network Alliance (DLNA) device side for recording which MAC addresses are permitted to access or use a service of the DLNA device or prohibited from accessing or using the service of the DLNA device;

one service control program is extended at the DLNA device side, and when there is another DLNA device transmitting a request to the DLNA device, an MAC address of the DLNA device is compared with the MAC address recorded by the MAC recording unit; and

if the MAC address of the DLNA device is in a permission list recorded by the MAC recording unit or the MAC address of the DLNA device is not in a prohibition list recorded by the MAC recording unit, then the request will be permitted;

otherwise the request will be rejected.

2. The method according to claim 1, wherein, the request comprises requiring a current DLNA device to provide Extensive Markup Language (XML) file of the service or requiring the service by using a service command.

3. The method according to claim 1, wherein, before the MAC address of the DLNA device is compared with the MAC address recorded by the MAC recording unit, the method further comprises:

parsing a request transmitted by another DLNA device to parse out an MAC address of the other DLNA device.

4. The method according to claim 1, wherein, if the MAC address of the DLNA device is in the permission list, a parsed-out IP data package is not modified, and an upper level service permits a control unit to obtain a device and service descriptor and permits the control unit to request;

otherwise, a FLAG tag is added in the parsed-out IP package, and the request is directly rejected by the DLNA device according to the FLAG.

5. The method according to claim 1, wherein, if the MAC address of the DLNA device is not in the prohibition list, the parsed-out IP data package is not modified, and the upper level service permits the control unit to obtain the device and service descriptor and permits the control unit to request;

otherwise, a FLAG tag is added in the parsed-out IP package, and the request is directly rejected by the DLNA device according to the FLAG.

6. An apparatus for controlling digital living network alliance contents, wherein, the apparatus comprises a Digital Living Network Alliance (DLNA) module, a Media Access Control (MAC) control module, and an MAC list module;

wherein,

the MAC list module stores information about which MAC addresses are permitted to access or use a service of a DLNA device or prohibited from accessing or using the service of the device;

the DLNA module obtains a request instruction transmitted by another DLNA device and forwards the instruction information to the MAC control module;

the MAC control module compares the MAC address transmitted by the other DLNA device with the MAC address recorded by the MAC list module, if the MAC address of the DLNA device is in a permission list which is recorded, or the MAC address of the DLNA device is not in a prohibition list which is recorded, then the request will be permitted;

otherwise the request will be rejected.

7. The apparatus according to claim 6, wherein, the request comprises requiring a current DLNA device to provide Extensive Markup Language (XML) file of the service or requiring the service by using a service command.

8. The apparatus according to claim 6, wherein, before comparing the MAC address of the DLNA device with the MAC address stored by the MAC list module, the MAC control module parses a request transmitted by another DLNA device to parse out an MAC address of the other DLNA device.

9. The apparatus according to claim 6, wherein, if the MAC address of the DLNA device is in the permission list, a parsed-out IP data package is not modified, and an upper level service permits the control module to obtain a device and service descriptor and permits the control module to request;

otherwise, a FLAG tag is added in the parsed-out IP package, and the request is directly rejected by the DLNA device according to the FLAG.

10. The apparatus according to claim 6, wherein, if the MAC address of the DLNA device is not in the prohibition list, the parsed-out IP data package is not modified, and the upper level service permits the control module to obtain the device and service descriptor and permits the control module to request;

otherwise, a FLAG tag is added in the parsed-out IP package, and the request is directly rejected by the DLNA device according to the FLAG.
