Abstract:
PROBLEM TO BE SOLVED: To provide a radio communication method for a magnetic field communication network with which a number of sensor nodes can be recognized in a short time, and a demodulation device for a coordinator.SOLUTION: A radio communication method for a magnetic field communication network includes: a step (a) performed by a coordinator in the magnetic field communication network for transmitting to a sensor node a requirement signal requiring a response; a step (b) for selecting any one of response signals received from the sensor node; a step (c) for transmitting an approval signal to the sensor node corresponding to the response signal selected in the step (b); a step (d) for selecting any one of response signals retransmitted from sensor nodes that can not receive the approval signal in the step (c); and a step (e) for transmitting an approval signal to a sensor node corresponding to the response signal selected in the step (d).

PROBLEM TO BE SOLVED: To provide a method for establishing smooth radio communication between a magnetic field communication network coordinator and an MFAN node.SOLUTION: The method for establishing smooth radio communication includes steps of: (a) transmitting a request packet for requesting one of network unification, network separation, network unification state confirmation, data transmission and group address setting; (b) receiving response packets from a node that receives the request packet; (c) selecting at least one of the response packets received in the step (b); (d) transmitting a response reception confirmation packet to a node corresponding to the response packet selected in the step (c); (e) receiving response packets retransmitted by nodes that do not receive the response reception confirmation packet of the step (d); (f) selecting at least one of the response packets received in the (e) step; and (g) transmitting response a reception confirmation packet to a nodes corresponding to the response packet selected in the step (f).
Abstract:
The present invention relates to a method or an operation for providing a personalized TV-Anytime metadata service. According to the present invention, there is provided a method of transmitting non-anonymous user metadata to a TV-Anytime service agent using a SOAP operation, comprising the steps of a) defining a SOAP operation which transmits user metadata and is capable of identifying transmission of non-anonymous user metadata, b) the service agent identifying a user, c) a client loading user metadata about the identified user on an element of the SOAP operation defined at step a) and transmitting the element with the user metadata to the service agent, and d) the service agent identifying the element of the SOAP operation transmitted at step c) and extracting the user metadata included in the element of the SOAP operation therefrom.
Abstract:
The present invention relates to a method or an operation for providing a personalized TV-Anytime metadata service. According to an embodiment of the present invention, there is provided a method of providing a table field element using a get_Data operation in the TV-Anytime metadata service. In the table field element provision method, a requested fields type element (RequestedFieldsType) required to designate a field of a metadata table is included in a query result value type in the SOAP query operation. A request message of the SOAP query operation is received. When the request message includes the requested fields type element for designating the query result value, a query result value corresponding to a designated table field is extracted from the requested fields type element included in the request message, and the query result value is transmitted using a response message of the SOAP operation.
