The boxes below the objects in fig. 2 show the state in which the adapter control point and the gateway control point, respectively, are located. The home gateway is initialized to be in a monitoring state after being powered on, and waits for connection requests of other devices (such as a digital television). After the digital television is switched on and switched off, the adapter control point in the television adapter sends a 'HELLO' message to the gateway control point of the home gateway, which indicates a connection request, and then is in a 'SYNSENT' state, if the adapter control point does not reply within a specified time, the adapter control point is always in the 'SYNSENT' state, and continues to send the connection request to the gateway control point. After receiving the HELLO message, the gateway control point of the home gateway replies an acknowledgement message "ACK ═ 1" to the adapter control point, and at the same time, assigns a unique device number "DEV ═ XXX" to the adapter where the adapter control point is located, and after the transmission is finished, the gateway control point is in a "SYNRCVD" state. After receiving the acknowledgement message and the device number assignment from the gateway, the adapter replies with an acknowledgement message "ACK ═ 1" and then is in a state of connection establishment, i.e., "ESTABLISHED". The gateway control point also enters a state of connection establishment ("ESTABLISHED" state) after receiving an acknowledgement message "ACK ═ 1" from the adapter control point. Thus, 3 handshaking processes of connection establishment are completed, and data exchange can be carried out subsequently. The specific steps of the connection establishment process are as follows:
step 1: after the home gateway is started up, a CLOSED state is converted into a LISTEN state, and after the home gateway is initialized, the adapter sends a connection request (HELLO message) to the gateway control point and is in a SYN-SENT state;
step 2: after receiving the HELLO message, the gateway control point replies an acknowledgement message to the adapter control point and allocates a device number to the adapter where the adapter control point is located, wherein "ACK is 1, DEVID is XXX", and then the gateway control point enters a state of "SYN-RCVD";
and step 3: the adapter control point enters into the 'ESTABLISHED' state after receiving the confirmation message, and simultaneously sends a 'ACK ═ 1' message to the gateway control point to confirm the establishment of the connection; after receiving the "ACK ═ 1" message sent by the adapter control point, the gateway control point enters the connection establishment state "ESTABLISHED", and the connection establishment process is ended.

In a specific implementation, as shown in fig. 3, the implementation of S105 is described as follows.
A typical data exchange process is shown in figure 3. Firstly, the adapter control point sends a Request message of 'Request P1' for a P1 channel, wherein the P1 channel can be obtained by the remote control operation of a user and the adapter control point receives and analyzes the Request message; after receiving the request message, the gateway control point judges whether the channel belongs to the current frequency point, if so, the gateway control point returns the channel address of the channel; the adapter control point sends the channel address to the streaming media player of the adapter where the adapter control point is located after obtaining the channel address; the streaming media player sends a media data request to the streaming media server through a channel address 'rtsp: P1'; and the streaming media server receives the streaming media data request and sends streaming media data (channel data) to the streaming media player. In a specific implementation, there may be heartbeat detection between the adapter control point and the gateway control point, so that both sides can confirm the existence of the other side, and this heartbeat time may be set to 1 minute or other.
When the digital home network system of the embodiment of the present invention includes a plurality of adapters, the method of the embodiment of the present invention may further include:
the home gateway locks the frequency point of the channel corresponding to the channel address requested by the main adapter in the television adapter;
the slave adapter in the television adapter sends channel request information to the home gateway;
the home gateway judges whether the channel corresponding to the channel request information is the frequency point of the channel corresponding to the channel address requested by the main adapter;
if yes, the home gateway sends the channel data to the slave adapter;
if not, the home gateway sends all channel addresses in the frequency point where the channel corresponding to the channel address requested to be obtained by the master adapter is located to the slave adapter.
As shown in fig. 4, the process is implemented as follows:
in the above data exchange process, the problem is related to whether the request is the current frequency point, and if not, the request needs to be processed additionally. Under the condition of a single user (a single television adapter), the streaming media server can switch frequency points and then return corresponding channel address information; however, in a digital home network environment with multiple users (multiple tv adapters), the current streaming media server can only lock one frequency point at a time, and each frequency point contains 7 digital tv channels, and each time all information of one frequency point is transmitted. The master adapter and the slave adapter are determined at the time of data connection establishment, that is, determined by the device number DEVID obtained by the adapter, the adapter that establishes a data connection with the home gateway a is the master adapter B, and then the slave adapter C. When the main adapter B requests a P1 channel, the home gateway A locks the F1 frequency point where the P1 is located, then transmits the data of the F1 to the main adapter B, and the main adapter B decodes the P1 channel data in the data of the F1. Requesting a P2 channel from the adapter C to the home gateway A, judging whether the P2 channel belongs to an F1 frequency point or not by the home gateway A, if so, transmitting F1 data to the slave adapter C, and then decoding P2 channel data from the adapter C in F1; if the P2 channel does not belong to the F1, the home gateway a reselects from the adapter C among the 7 channels provided by F1 for all channel information returned from the adapter C to F1. From the adaptor C, any one of the channels in F1 may be selected, or the user may select to abandon and exit.
After S105, the following steps may be further included:
the television adapter sends a connection release message to the home gateway;
and the home gateway disconnects the connection between the home gateway and the television adapter according to the connection release message.
Fig. 5 shows the connection release procedure of the inventive method.
When the main adapter B is to exit, a 'GOODBYE' message is sent to the home gateway A; after receiving the exit message of the host adapter B, the home gateway A stops data transmission to the host adapter B and revokes the device number of the host adapter B; the home gateway a selects one of the original slave adapters as a new master device, and as shown in fig. 5, may select an adapter C and send a selected notification message to the adapter C; the adapter C returns an acknowledgement message; this completes the exit of the host adapter B and the selection of a new host adapter C. If a slave adapter, such as slave adapter C, is exited, only the connection release process need be performed, rather than the master adapter's more election process.
It should be noted that if an adapter is accidentally logged out, the home gateway may check whether the adapter is present by heartbeat detection. If not, its device number is revoked. If the home gateway is unexpected, the adapter can also confirm whether the home gateway exists through heartbeat detection.
In the embodiment of the invention, reliable communication between the digital television and the home gateway can be realized through establishment of connection, transmission of data and release of connection, a plurality of digital televisions (particularly television adapters) can be controlled and managed more effectively by adding fields such as 'DEVID' and the like in a message frame, and in addition, the purpose of rapid development can be realized.
