Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

As shown in Figure 1, a kind of multimedia access processing method of the embodiment of the present invention is applied to a set-top box, including:

Step 101, obtaining the entry address of the multimedia service;

Step 102, generate multimedia proxy access information according to the entry address, where the proxy access information includes multimedia content link addresses and user authentication information. By above-mentioned step 101 and step 102, apply the set-top box of the multimedia access processing method of the embodiment of the present invention, by obtaining the entrance address of multimedia service, then generate proxy access information that comprises multimedia content link address and user authentication information according to this entrance address, In order to subsequently provide the EPG access proxy service for the terminal equipment wirelessly connected with the set-top box to complete the multimedia access without setting up an additional set-top box, thereby reducing costs and avoiding waste of resources.

It should be known that after the set-top box is started, it will initiate user authentication and periodically access the EPG page of the operator's video service, so that the entry address of the multimedia service can be obtained. The entry address may be an EPG page, or a link address of the multimedia content extracted from the EPG page. Of course, user authentication is re-authenticated regularly according to time to ensure the timeliness of authentication. At the same time, with the completion of re-authentication, the proxy access information will be updated.

User authentication information includes, but is not limited to: terminal ID of the set-top box, user ID, user password encrypted authentication information, time stamp, and anti-leech information. In this way, the proxy access information composed of user authentication information and multimedia content link address actually forms a multimedia content link that can be authorized to access, and can provide EPG access proxy service for terminal equipment wirelessly connected to the set-top box. Specifically, a proxy EPG page is provided for the terminal device, so that the user can select the multimedia to be accessed.

Optionally, generating proxy access information corresponding to multimedia in step 102, including:

Obtaining the link address of the multimedia content in the electronic program guide through the entry address;

The user authentication information is added to the multimedia content link address to obtain multimedia proxy access information.

Here, through the entry address obtained in step 101, such as the EPG page, the multimedia content link address in the EPG is obtained, and then the user authentication information is added to the multimedia content link address, and finally the multimedia proxy access information is obtained. For example, for a video content link address, the proxy access information after adding user authentication information is:

(rtsp/http...)://IP:PORT/host/CMSID/ContentID? AuthInfo=%2B9BrGTSqoMWrCMVhJWQqtKATlHImKh5fCZ0OePD4cL50hafeKnkQ83EBHsaurb8x&STBID=009903FF0018446000EFA8BD3A501A2E&UserId=15000123458&TimeStamp=1299046644

Among them, ContentID is the content ID, STBID is the set-top box terminal ID, UserId is the user ID, TimeStamp is the timestamp, and AuthInfo is the anti-leech information, which is generated by the above information plus the user password through encryption and coding algorithms.

It should also be known that after the multimedia proxy access information is generated, an EPG access proxy service will be provided for the terminal device wirelessly connected to the set-top box based on the proxy access information. Optionally,

After the proxy access information for multimedia is generated, it also includes:

In response to the search of the internal network by the terminal device, sending the agent access information to the terminal device.

Specifically, the set-top box can provide the EPG access proxy service through the Universal Plug and Play UPnP service. Through the local area network file sharing discovery mechanism of UPnP, the terminal device can search the home intranet and find the proxy access information shared by the set-top box, which includes multimedia content links that can be authorized for access. The user of the terminal device can click the target item in the interface corresponding to the target multimedia to trigger access to the target multimedia through the EPG proxy interface (EPG proxy page) generated based on the proxy access information.

The terminal device responds to the user clicking the target item in the interface corresponding to the target multimedia to be accessed through the EPG proxy interface generated based on the proxy access information, and generates its own stream according to the link address of the target multimedia content and the terminal device streaming media management protocol stack The media management message initiates an access request to the streaming media server.

If the target video content link address is an HTTP-based streaming media protocol, such as the HLS protocol, the field information of the user authentication information required by the streaming media management protocol has been included in the HTTP video content link address URL, and the TV station can directly follow the URL Access, initiate a streaming media request to the operator's streaming media server. If the target video content link address is based on other streaming media protocols, such as IGMP/RTSP, etc., the fields related to user authentication information are not reflected in the video content link on the EPG, but are added to the message field by the underlying protocol stack . Although the streaming media protocol messages of the terminal device and the set-top box are the same in the process of sending the message, there are differences in the version of the protocol message and the definition of specific fields, which need to be processed by the gateway. Therefore, in this embodiment, optionally, the method further includes:

receiving a first access request triggered by a user selecting a target item on an EPG agent interface, wherein the EPG agent interface is generated based on the agent access information;

Sending a second access request to the target gateway according to the first access request, wherein the source IP address of the second access request is the IP address of the device sending the first access request.

Here, the set-top box will receive the terminal device's first access request triggered by the user clicking on the target item in the interface corresponding to the target multimedia to be accessed through the EPG proxy interface generated based on the proxy access information, and understand the user's access requirements of the terminal device , so as to send the second access request to the target gateway, so as to realize the access to the target multimedia. Wherein, the source Internet Protocol IP address of the second access request is the IP address of the device sending the first access request, so that the network knows the device with access requirements when receiving the second access request.

In order to realize access to the target multimedia, in this embodiment, optionally, the first access request includes the link address of the target multimedia content and user authentication information;

As shown in Figure 2, according to the first access request, sending a second access request to the target gateway, including:

Step 201, obtaining the target multimedia content link address and user authentication information in the first access request;

Step 202, generating a streaming media management message according to the link address of the target multimedia content and the user authentication information;

Step 203: After modifying the source IP address of the streaming media management message to the IP address of the sending end of the first access request, initiate a second access request to the target gateway.

In this way, the set-top box will obtain the target multimedia content link address and user authentication information from the received first access request, and then generate a streaming media management message according to the target multimedia content link address and user authentication information, and send the generated After the source IP address of the streaming media management message is changed to the IP address of the sender of the first access request, a second access request is initiated to the target gateway. Wherein, the generation of the streaming media management message is completed by filling the protocol version and field organization required by the operator with the streaming media management protocol stack of the set-top box.

Wherein, the identifier of the streaming media management message indicates that the streaming media management message is a proxy message.

In this way, after receiving the second access request, the gateway determines that the streaming media management message is a proxy message through the identifier indication of the streaming media management message.

The gateway can sniff and proxy the streaming media management packets sent by the set-top boxes and terminal devices in all network packets through streaming media management protocol sniffing and proxying. Wherein, the gateway will start a timeout mechanism to wait for the message from the other party after receiving the message from one party. The timeout value of the timeout mechanism is set according to the possible time difference between the two transmissions, while taking into account the user experience, preferably no more than 1s.

After the gateway sniffs the streaming media management message sent by the set-top box and the terminal device to the gateway within the Timeout time, it judges whether the two match based on the preset parameters. The streaming media request triggered by the provided EPG access proxy service sends an access request to the streaming media server. Wherein, the preset parameters for matching reference include but not limited to protocol type and address fields, and may also include protocol version and source port number.

For example, an example of IGMP packet matching is as follows:

The set-top box sends an IGMP V2 Report message:

IGMP V2 Membership Report(IGMP join)

IGMP Version: 2

Type: Membership Report (0x16)

Max Response Time: 0.0sec(0x00)

Header checksum: 0xABCD (eg 0xfe8f means correct)

Multicast Address: x.x.x.x;

The terminal device (TV) sends the Report message of IGMP V3:

IGMP V3 Membership Report (IGMP join)

IGMP Version: 3

Type: Membership Report (0x22)

Max Response Time: 1.0sec(0x00)

Header checksum: 0xABCD (eg 0xfe8f means correct)

Multicast Address: x.x.x.x.

The gateway can match according to the correlation of the contents of the two message fields. For example, both are IGMP protocol types, but the protocol versions are different, and the message subtype fields indicate differences but both are IGMP Report message types. The broadcast address is the same as the Multicast Address.

In addition, the gateway will send an access request to the streaming media server when the two match. Increase the device attribute information of the terminal device, such as device identification, device physical address, etc.

Moreover, in this embodiment, the gateway will also add a forwarding rule, and set the source port of the message receiving the access request of the terminal device as the forwarding port of the destination address of the accessed streaming media content message. In this way, after the streaming media server receives the access request, it sends the downstream streaming media content message to the gateway, and the gateway can forward the streaming media content message to the terminal device according to the forwarding rules set, and the terminal device receives the streaming media content After the message, call the player to play the content.

In the following, the EPG page access process for video access by the TV is described in conjunction with FIG. 3 :

The set-top box initiates user authentication, and periodically accesses the EPG page of the operator's video service; the set-top box traverses the video content link address in the EPG page, and adds user authentication information (which may include the set-top box terminal ID, user ID, user password encrypted authentication information, Timestamp, anti-leeching information, etc.), form video content links that can be authorized to access, further form proxy EPG pages, and provide proxy access services for EPG pages through UPnP services. The TV searches the family intranet through the UPnP LAN file sharing discovery mechanism, and finds the EPG proxy page shared by the set-top box. The page contains video content links that can be authorized to be accessed; The EPG proxy page allows the user to browse the content of the EPG page.

In conjunction with Figure 4, the streaming media access process for TV access to video is described:

After the home gateway is powered on, the streaming media management protocol sniffing and proxy module is started; the user selects the video content of interest on the proxy EPG page on the TV, and clicks to access the video content link address. The set-top box responds to the click action of the link, and according to the link address of the accessed video content, the set-top box streaming media management protocol stack fills in the protocol version and field organization required by the operator to form an operator streaming media management message, and at the same time, the source IP address of the message is changed to TV IP address of the TV set and identified as a proxy message, and initiates a request to the streaming media server; at the same time, the TV responds to the click action, and according to the link address of the accessed video content, the TV streaming media management protocol stack generates its own streaming media management message and sends it to the streaming media server. The media server initiates a request; the home gateway sniffs the streaming media management messages sent by the set-top box and the TV in all network messages, and after receiving one of the messages, it starts a timeout mechanism and waits for the other party's messages (the Timeout value does not exceed 1s); the home gateway streaming media management protocol sniffing and proxy module sniffs the streaming media management packets sent by 2 devices within the Timeout time, and records the protocol type, protocol version, and source port number received by the 2 packets , and match according to the address fields in the two messages. If they match, it is determined that the streaming media request is triggered by the TV set-top box by accessing the proxy EPG page; the home gateway streaming media management protocol sniffing and proxy module sends the set-top box The streaming media management message continues to be sent, and a playback request is initiated to the streaming media server; at the same time, in the streaming media routing and forwarding module, a forwarding rule is added to set the source port of the message sent by the TV set to the requested streaming media content message The forwarding port of the destination address; after receiving the request, the streaming media server sends the downlink streaming media content message to the home gateway, and the home gateway forwards the message to the TV according to the forwarding rules previously set in the streaming media routing and forwarding module , after the TV receives the video content message, it invokes the player to play the content.

Therefore, in this embodiment, the set-top box has realized: preset EPG access entrance, and provide EPG access proxy service, provide the access link of video content; Provide EPG proxy entrance; User authentication, and provide authentication proxy service; Generate customized streaming media management messages. The gateway realizes: the detection intercepts the streaming media management protocol message sent by the set-top box and the terminal device, and according to the field association relationship between the messages (such as the address of the video content to be accessed, the sending source address, the agency relationship, etc.), the proxy terminal device The modified streaming media management message sent to the streaming media server; the streaming media message is forwarded to the corresponding network interface where the streaming media requesting terminal is located. The terminal device realizes: discovering the EPG agent entrance; opening the EPG agent entrance, and presenting the EPG agent page; according to the link address of the multimedia content in the EPG, sending a stream media management protocol message conforming to itself to the stream media server; obtaining and receiving the stream Media transmission message; perform multimedia playback on the content of the received streaming media message.
