step 1: and the human-computer interaction relay device sends a human-computer interaction interface to the remote controller.

The human-computer interaction relay device can be triggered to send a human-computer interaction interface to the remote controller in two ways:

the first method is as follows: and the human-computer interaction relay device actively sends a human-computer interaction interface to the remote controller according to a preset first preset strategy.

The first preset strategy can be permanently preset in the human-computer interaction relay device or set by a user. The first preset strategy is preset in the human-computer interaction relay device and used for determining a human-computer interaction interface to be sent and a display party of the human-computer interaction interface.

In the first mode, when the human-computer interaction interface is detected, the human-computer interaction relay device can actively send the human-computer interaction interface to the remote controller according to the first preset strategy arranged on the human-computer interaction relay device. Such as: the man-machine interaction relay device can determine that the man-machine interaction interface is detected and send the man-machine interaction interface under the condition that the received media content indication information is matched with the first preset strategy.

The second method comprises the following steps: and after receiving the human-computer interaction interface request of the remote controller, the human-computer interaction relay device sends a human-computer interaction interface to the remote controller.

In the second mode, the human-computer interaction interface request sent by the remote controller includes: the requested human-computer interaction interface may further comprise a human-computer interaction interface display indication for indicating a destination of the human-computer interaction interface display, such as a remote control, or a remote control and a TV. In addition, the human-computer interaction interface request can also carry an indication of the owner of the human-computer interaction interface, such as an STB identity.

After receiving the human-computer interaction interface request from the remote controller, the human-computer interaction relay device matches the stored media content indication information with the requested human-computer interaction interface carried in the human-computer interaction interface request sent by the remote controller, searches the human-computer interaction interface requested by the remote controller, and requests the appointed human-computer interaction interface from the IPTV network when the human-computer interaction interface requested by the remote controller is not found.

In the second mode, the display party of the human-computer interaction interface sent by the human-computer interaction relay device to the remote controller can be specified according to the human-computer interaction interface display party carried in the human-computer interaction interface request sent by the remote controller, or can be specified according to the first preset strategy, or can be specified by combining the two.

In the first or second mode, when the human-computer interaction relay device is an STB, the user may set the first preset policy directly on the STB or set the first preset policy on the STB through the remote controller (e.g., set by the STB receiving a human-computer interaction interface request from the remote controller). If the set first preset strategy is that the STB receives an EPG (Electronic Program Guide), that is, an Electronic Program menu when being turned on, that is, when the STB receives the EPG, the EPG is simultaneously sent to the TV and the remote controller; if the preset strategy is that the STB receives the EPG update content, only sends the EPG update content to the remote controller; and if the STB receives the EPG update content and the current display content on the TV is the EPG, the EPG update content is simultaneously sent to the TV and the remote controller. And when the remote controller has an identity, the preset strategy can also comprise the identity of the remote controller.

And when the remote controller has the identity, the remote controller can be directly configured on the network entity, can be set in the network entity through the remote controller by a user, and can also be used for controlling the STB to set in the network entity. And, in the first preset policy, an identity of the remote controller may also be included.

Step 2: and the remote controller receives and displays the human-computer interaction interface.

Under the condition that the remote controller sends a man-machine operation request to the man-machine interaction relay device, the method further comprises the following steps:

and step 3: and the remote controller initiates a man-machine operation request to the man-machine interaction relay device.

The human machine operation request may include: user operation events, or standard interactive programs (such as SIP, HTTP, RTSP messages, etc.), or the man-machine operation request also carries: at least one of the identification information of the remote controller and a human-machine operation response display party indication for indicating a human-machine operation response display party.

Such as: the user operation event may include: the user operation event corresponding to the coordinate point (x, y) on the click screen is press (x, y), and the user operation event corresponding to the click EPG program list is press (Vod1@ Vodas. com) (an identifier of a program). The standard interactive program comprises: a SIP invite or Subscribe message, a HTTP get or post message, etc.

The man-machine operation response display party can be input by a user on the remote controller or selected by the user in a preset list of the remote controller.

The human machine operation request message may be a standard interactive message, such as a SIP message, an HTTP message, an RTSP message, and the like.

And 4, step 4: and the human-computer interaction relay device receives a human-computer operation request sent by the remote controller and sends a human-computer operation response to the human-computer operation response display party.

Under the condition that the human-computer interaction interface does not carry a standard interaction program, the human-computer operation request comprises a user operation event, the human-computer interaction relay device receives the user operation event, calls the standard interaction program corresponding to the user operation event, carries out corresponding processing, and sends a human-computer operation response to the determined human-computer operation response display party according to a processing result;

and under the condition that the human-computer interaction interface carries a standard interaction program, the human-computer operation request comprises a standard interaction message corresponding to the standard interaction program, the human-computer interaction relay device receives the standard interaction message, performs corresponding processing, and sends a human-computer operation response to the determined human-computer operation response display party according to a processing result.

And under the condition that the man-machine interaction relay device cannot process the standard interaction message, the man-machine interaction relay device sends a man-machine operation request carrying the standard interaction message to a man-machine interaction control device and receives a man-machine operation response sent by the man-machine interaction control device.

The human-computer operation response sent by the human-computer interaction control device comprises the following steps: a man-machine operation response display party; the man-machine operation response display party is determined by at least one of a third preset strategy preset in the man-machine interaction control device and a man-machine operation request received by the man-machine interaction control device. The third preset strategy is arranged in the man-machine interaction control device and used for determining a man-machine operation response display party.

Under the condition that the human-computer interaction relay device does not send a human-computer operation request to the human-computer interaction control device, the human-computer interaction relay device determines a human-computer operation response display party according to at least one of a second preset strategy preset on the human-computer interaction relay device and the received human-computer operation request; the second preset strategy is arranged in the man-machine interaction relay device and used for determining a man-machine operation response display party.

And under the condition that the human-computer interaction relay device sends a human-computer operation request to the human-computer interaction control device, the human-computer interaction relay device determines a human-computer operation response display party according to at least one of a second preset strategy, a received human-computer operation request and a received human-computer operation response preset on the human-computer interaction relay device.

The human-computer interaction relay device may transmit the second human-computer operation request to the human-computer interaction control device through the I2 interface.

In this way, the human-machine operation request from the remote controller is first transmitted to the human-machine interaction relay device via the I1 interface, and then transmitted to the human-machine interaction control device via the I2 interface. The human-machine operation request messages transmitted on the I1 and the I2 interfaces can be inconsistent, including the type of the human-machine operation request messages can be inconsistent, for example, the human-machine operation request messages transmitted on the I1 interface are infrared messages, and the human-machine interaction relay device translates the messages into SIP or HTTP messages to be transmitted to the human-machine interaction control device through the I2 interface; if the human-computer operation request message transmitted on the interface I1 is an SIP refer message, the human-computer interaction relay device translates the message into an SIP invite message, and the SIP invite message is transmitted to the human-computer interaction control device through the interface I2; and if the man-machine operation request message transmitted on the I1 interface is an infrared message, the man-machine interaction relay device translates the man-machine operation request message into an STB internal interface message and transmits the STB internal interface message to the man-machine interaction control device through the I2 interface. The specific content of the human-machine operation request message can be inconsistent, for example, the human-machine interaction relay device can add, modify or delete any one or more of user operation events, standard interaction messages, interaction request result display party indications and the like on the basis of the human-machine operation request message received by the I1 interface; if the human-computer interaction relay device receives the human-computer operation request message carried by the user operation event, executing a program called by the user operation event, thereby determining and modifying the human-computer operation request as a standard interaction message; and if the human-computer interaction relay device stores the indication of the human-computer operation response display party received by the I1 interface, the human-computer operation response display party is modified into the user.

The human-machine operation response display side comprises: at least one of a remote controller and a TV.

The contents of the human-machine operation response can be divided into: human-machine interface and/or program content.

Step 1: when a user wants to browse the EPG corresponding to the STB identity on the remote controller, the user needs to select the STB identity in a preset list or input the STB identity, and presses an EPG menu key on the remote controller;

step 2: the remote controller executes a program corresponding to user operation, generates an HTTP URI (HTTP Uniform Resource Identifier, U RI, Uniform Resource Identifier) and an HTTP get human-computer interaction interface request, and sends the request to a protal AS, wherein the request carries an STB identity Identifier, an EPG indication and a remote controller identity Identifier;

GetHTTP://EPG.com/zh-cn/epg.htmlstb@iptv.com&lang＝zh-CN&cert＝false

X-3GPP-Intended-Identity:”sip:rm@iptv.com”

com represents the requested EPG information, sid @ iptv.com represents the EPG information of the requested STB, and X-3 GPP-ended-Identity represents that the HTTP request is a request sent by a remote controller;

and step 3: the Portal AS searches the EPG AS where the EPG corresponding to the STB identity is located, routes the HTTP request to the EPG AS where the STB EPG is located, and can be obtained by inquiring a data management entity such AS UPSF and the like or searched in self-configured data;

and 4, step 4: the EPG AS authenticates and judges whether the remote controller has the right to obtain the EPG information of the STB, if so, judges whether the remote controller and the STB have an incidence relation;

and 5: after the authentication is passed, the EPG AS returns a 200OK message to the Portal AS, and the message carries EPG information corresponding to the STB identity identifier;

step 6: the Portal AS forwards the 200OK message to the remote controller.

Wherein, the step 3, the step 4, the step 5 and the step 6: or the portal AS sends a subscription subscribe request to the EPG AS through the IMS core, where the subscription request carries an identity of the STB, an EPG indication, and an identity of the remote controller, such AS:

Subscribe Sip:stb@iptv.com SIP/2.0

From:<Sip:rm@iptv.com>

To:<Sip:EPGAS@iptv.com>

Event:EPG

the EPG AS can return the EPG interface of the STB in the Notify response of the Subscribe, or return the multicast group address of the EPG interface in the Notify, the Portal AS adds the multicast group to obtain the EPG interface, and then packages the obtained EPG interface in the 200OK response and returns the EPG interface to the remote controller.

In this example, when the remote controller and the STB have the same common Identity, the request process is similar, and only the X-3 GPP-ended-Identity in step 6 is sip: STB @ iptv.com.
