Detailed Description
To make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a multimedia access processing method according to an embodiment of the present invention is applied to a set top box, and includes:
and 102, generating multimedia proxy access information according to the entry address, wherein the proxy access information comprises a multimedia content link address and user authentication information. From the above step 101 and step 102, the set top box applying the multimedia access processing method of the embodiment of the present invention generates the proxy access information including the multimedia content link address and the user authentication information according to the entry address by acquiring the entry address of the multimedia service, so as to subsequently provide the electronic program guide access proxy service for the terminal device wirelessly connected to the set top box, thereby completing the multimedia access without setting an additional set top box, reducing the cost, and avoiding the resource waste.
It should be noted that the set-top box, when started, initiates user authentication and periodically accesses the EPG page of the operator video service, so that the entry address of the multimedia service can be obtained. The entry address may be an EPG page or a multimedia content link address extracted from an EPG page. Certainly, the user authentication is re-authenticated periodically according to time to ensure the timeliness of the authentication, and meanwhile, the agent access information is updated along with the completion of the re-authentication.
The user authentication information includes, but is not limited to: the terminal identification, the user password encryption authentication information, the timestamp and the anti-theft chain information of the set top box. Therefore, the proxy access information consisting of the user authentication information and the multimedia content link address actually forms the multimedia content link which can be accessed by authorization, and can provide the electronic program guide access proxy service for the terminal equipment wirelessly connected with the set top box. Specifically, a proxy EPG page is provided for the terminal device for the user to select the multimedia to access.
Optionally, the generating proxy access information of the corresponding multimedia in step 102 includes:
acquiring a multimedia content link address in the electronic program guide through the entry address;
and adding the user authentication information to the multimedia content link address to obtain the multimedia proxy access information.
Here, the entry address, such as the EPG page, obtained in step 101 is used to obtain the multimedia content link address in the EPG, and then the user authentication information is added to the multimedia content link address, so as to finally obtain the multimedia proxy access information. For example, a video content link address, the proxy access information after adding the user authentication information is:
(rtsp/http…)://IP:PORT/host/CMSID/ContentIDAuthInfo＝％2B9BrGTSqoMWrCMVhJWQqtKATlHImKh5fCZ0OePD4cL50hafeKnkQ83EBHsaurb8x&STBID＝009903FF0018446000EFA8BD3A501A2E&UserId＝15000123458&TimeStamp＝1299046644
wherein, contentID is content identification, STBID is set-top box terminal identification, userId is user identification, timeStamp is time stamp, authInfo is anti-theft chain information, and the information and user password are generated through encryption and coding algorithm.
It should also be appreciated that after generating the proxy access information for the multimedia, the electronic program guide access proxy service is provided to the terminal device wirelessly connected to the set-top box based on the proxy access information. Alternatively, the first and second liquid crystal display panels may be,
after generating the agent access information of the multimedia, the method further comprises the following steps:
and responding to the search of the terminal equipment in the intranet, and sending the agent access information to the terminal equipment.
Specifically, the set-top box may provide an EPG access proxy service through a universal plug and play UPnP service. The terminal equipment can search the home intranet through a UPnP local area network file sharing discovery mechanism and discover the proxy access information which is provided by the set-top box in a sharing way, wherein the proxy access information comprises a multimedia content link which can be authorized to access. And the user of the terminal equipment can trigger the access to the target multimedia by clicking the target item corresponding to the target multimedia to be accessed in the interface through an EPG proxy interface (EPG proxy page) generated based on the proxy access information.
The terminal equipment responds to an EPG proxy interface generated by a user through proxy access information, clicks a target item corresponding to a target multimedia to be accessed in the interface, and generates a self streaming media management message according to a target multimedia content link address and a streaming media management protocol stack of the terminal equipment, and initiates an access request to a streaming media server.
If the target video content link address is a streaming media protocol based on HTTP, such as HLS protocol, the field information of the user authentication information required by the streaming media management protocol is already contained in the video content link address URL of HTTP, and the tv node can directly access according to the URL to initiate a streaming media request to the streaming media server of the operator. If the destination video content link address is based on other streaming media protocols, such as IGMP/RTSP, etc., the field related to the user authentication information is not embodied in the video content link on the EPG, but is 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 messages, the versions and specific field definitions of the protocol messages are different, and the messages need to be processed by a gateway. Therefore, in this embodiment, optionally, the method further comprises:
receiving a first access request triggered by a user selecting a target item on an electronic program guide proxy interface, wherein the electronic program guide proxy interface is generated based on the proxy access information;
and sending a second access request to a target gateway according to the first access request, wherein the source internet protocol address of the second access request is the internet protocol address of the equipment sending the first access request.
Here, the set top box receives a first access request triggered by the terminal device through an EPG proxy interface generated by the user based on proxy access information by clicking a target item in the interface corresponding to a target multimedia to be accessed, learns an access requirement of the user of the terminal device, and sends a second access request to the target gateway to realize access to the target multimedia. And the source internet protocol IP address of the second access request is the IP address of the equipment sending the first access request, so that the network knows the equipment with the access requirement when receiving the second access request.
In order to realize the access to the target multimedia, in this embodiment, optionally, the first access request includes a target multimedia content link address and user authentication information;
as shown in fig. 2, sending a second access request to the target gateway according to the first access request includes:
Therefore, the set top box can acquire the target multimedia content link address and the user authentication information from the received first access request, then generate a streaming media management message according to the target multimedia content link address and the user authentication information, modify the source IP address of the generated streaming media management message into the IP address of the first access request sending end, and then initiate a second access request to the target gateway. The generation of the streaming media management message is completed by filling a protocol version and a field organization required by an operator in a 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 an agent message.
In this way, after receiving the second access request, the gateway determines that the streaming media management message is the proxy message according to the identifier indication of the streaming media management message.
The gateway can sniff the streaming media management messages sent by the set top box and the terminal equipment in all network messages through a streaming media management protocol sniffing and acting. After receiving the message of one party, the gateway starts a timeout mechanism to wait for the message of the other party. The time duration Timeout value of the Timeout mechanism is set according to the possible time difference between the two sending times, and the user experience is considered at the same time, and preferably does not exceed 1s.
After sniffing the streaming media management messages sent to the gateway by the set top box and the terminal equipment within the Timeout period, the gateway judges whether the set top box and the terminal equipment are matched based on preset parameters, thereby determining that the terminal equipment is a streaming media request triggered by the EPG access proxy service provided by the set top box under the condition of matching, and sending an access request to a streaming media server. The preset parameters of the matching reference include, but are not limited to, a protocol type and an address field, and may also include a protocol version and a source port number.
For example, an example of IGMP packet matching is as follows:
the set top box sends a Report message of IGMP V2:
IGMP V2 Membership Report(IGMP join)
IGMP Version:2
Type:Membership Report(0x16)
Max Response Time:0.0sec(0x00)
header checksum:0xABCD (e.g., 0xfe8f for correct)
Multicast Address:x.x.x.x；
The terminal equipment (television) sends a 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 (e.g., 0xfe8f for 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, the message fields are both IGMP protocol types but have different protocol versions, the message subtype fields represent the difference but are both IGMP Report message types, and the Multicast addresses added by the two message fields are the same.
In addition, the gateway sends an access request to the streaming media server under the condition that the two are determined to be matched, wherein the access request can be an access request of a directly forwarded set top box, and can also be combined with a received access request of the terminal device to add device attribute information of the terminal device, such as device identification, device physical address and the like, in the forwarded access request.
In addition, in this embodiment, the gateway further adds a forwarding rule, and sets a message source port that receives an access request from the terminal device as a forwarding port of a destination address of the accessed streaming media content message. Thus, after receiving the access request, the streaming media server sends a downstream streaming media content message to the gateway, the gateway can forward the streaming media content message to the terminal device according to the set forwarding rule, and the terminal device calls the player to play the content after receiving the streaming media content message.
The following describes an EPG page access flow for video access by a television set with reference to fig. 3:
the set top box initiates user authentication and periodically accesses an EPG page of the video service of an operator; the set-top box traverses the video content link address in the EPG page, adds user authentication information (comprising set-top box terminal identification, user password encryption authentication information, time stamp, anti-stealing link information and the like), forms a video content link which can be authorized to access, further forms a proxy EPG page, and provides proxy access service for the EPG page through UPnP service. The television searches for an intranet in a home through a UPnP local area network file sharing discovery mechanism, discovers an EPG proxy page provided by the set top box in a sharing way, and the page comprises video content links for authorized access; after the user clicks the EPG proxy page file, the TV browser loads the EPG proxy page, and the user can browse the EPG page content.
The flow of accessing streaming media for video access by a television is described with reference to fig. 4:
after the home gateway is powered on, a stream media management protocol sniffing and proxy module is started; and selecting the interested video content on the proxy EPG page on the television by the user, and clicking to access the video content link address. The set-top box responds to the link click action, according to the link address of the accessed video content, a set-top box streaming media management protocol stack fills a protocol version and a field required by an operator to organize and form an operator streaming media management message, and meanwhile, a source IP address sent by the message is modified into a television IP address and is marked as an agent message, and a request is initiated to a streaming media server; meanwhile, the television responds to the click action, and according to the link address of the accessed video content, the television streaming media management protocol stack generates a self streaming media management message and initiates a request to a streaming media server; the home gateway sniffs the streaming media management messages sent by the set top box and the television in all network messages, and after receiving the message of one party, starts a Timeout mechanism to wait for the message of the other party (the Timeout value is not more than 1 s); the home gateway streaming media management protocol sniffing and proxy module sniffs streaming media management messages sent by 2 devices in the Timeout time, records protocol types, protocol versions and source port numbers received by the 2 messages, matches the protocol types, the protocol versions and the source port numbers according to address fields in the 2 messages, and if the protocol types, the protocol versions and the source port numbers are matched, the protocol types, the protocol versions and the source port numbers are determined to be streaming media requests triggered by a television through accessing an EPG page of a proxy of a set top box; the home gateway streaming media management protocol sniffing and agent module continuously sends out a streaming media management message sent by the set top box and initiates a play request to a streaming media server; meanwhile, in the streaming media routing and forwarding module, a forwarding rule is added, and a source port of a message sent by the television is set as a forwarding port of a destination address of a requested streaming media content message; after receiving the request, the streaming media server sends a downlink streaming media content message to the home gateway, the home gateway forwards the message to the television according to the forwarding rule set in the streaming media routing forwarding module, and the television calls the player to play the content after receiving the video content message.
Therefore, in this embodiment, the set-top box implements: presetting an EPG access entry, providing EPG access proxy service and providing access links of video contents; providing an EPG proxy entrance; user authentication and authentication proxy service provision; and generating a customized streaming media management message. The gateway realizes that: detecting and intercepting a streaming media management protocol message sent by a set top box and a terminal device, and sending a modified streaming media management message to a streaming media server by an agent terminal device according to field incidence relations (such as video content addresses to be accessed, sending source addresses, agent relations and the like) between the messages; and forwarding the streaming media message to a network interface where the corresponding streaming media request terminal is located. The terminal equipment realizes that: discovering an EPG proxy entry; opening an EPG proxy entrance and presenting an EPG proxy page; sending a streaming media management protocol message which accords with the streaming media server to the streaming media server according to the multimedia content link address in the EPG; acquiring and receiving a streaming media transmission message; and playing the multimedia according to the received streaming media message content.
In summary, the method of the embodiment of the present invention can generate the proxy access information including the multimedia content link address and the user authentication information according to the entry address by obtaining the entry address of the multimedia service, so as to subsequently provide the electronic program guide access proxy service for the terminal device wirelessly connected to the set top box, thereby completing the multimedia access without setting an additional set top box, reducing the cost, and avoiding the resource waste.
