Detailed Description
Fig. 1 is a system architecture diagram for implementing the technical solution of the embodiment of the present invention, and the following description is provided for the connection relationship and the network element functions of the network elements in the system architecture as follows:
ums (unified Management system): and (5) a unified management system. And managing data of users, contents, services and the like, and sending the data of the users, the contents and the services to the EPG Server or the CDN according to the needs.
EPG Server (Electronic Program Guide): and an electronic program guide server. The method is a portal background server for system display and experience. The EPG Server acquires data display of content, user, service and the like from the UMS, and completes services of service authentication, ordering and the like of the user in interactive cooperation with the UMS.
Cdn (content Delivery network): a content distribution network. Systems for distributing content, particularly media content, to end users. The CDN obtains content from the UMS and distributes the content to the end user, and may also obtain data such as a user and a service from the UMS as necessary.
Terminal: terminal equipment or user terminal. Including STB, Phone, Pad, PC, etc., for the user to experience IPTV, OTT, etc. The Terminal interacts with the EPG Server to complete the display of the EPG program list and the service processing of the Terminal user, and interacts with the CDN to obtain the media content stream.
Program metadata: the description information of the program comprises: program name, description, whether catch-upTV (review recording) is supported, whether nPVR (network side personal recording) is supported, start or end time of the program, and the like.
Through the system architecture, the user terminal equipment can realize the acquisition and playing of media contents, but the programs are rich and diverse and are not necessarily suitable for all users, and the current shielding mechanism for the programs mainly depends on the capability of the terminal.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Fig. 2 is a schematic diagram of a method for issuing program content according to an embodiment of the present invention, based on the foregoing network architecture and concept in fig. 1, where the method includes:
s201, receiving program data sent by the UMS by the CDN, wherein the program data comprises shielding information of the program;
the mask information field may be extended over The metadata of The IPTV unicast or ott (over The top) programs, which may be described positively, e.g., "isBlackout", or negatively, e.g., "isnotblakout". The shielding information may include user characteristic values such as areas and user groups, and may shield a specific program for all users or some users, and the shielding may be blocking a data stream or playing an alternative program instead. The screening of partial users can screen the specified programs according to the users of the user group, and the characteristic attributes for distinguishing the users can be used as extended capabilities, such as user brand, user grade, age, gender, interests, hobbies, religious beliefs and the like, and can be carried in one or more specific screening information singly or in combination.
In the following, for example, the shielding attribute is described positively, the information structure of isBlackout may be represented by a data symbol, and the code for shielding a specific program for all users may be: isBlackout ═ true | false >, i.e. the program is masked off for all users; if instead an alternate program is shown, the code may be: isBlackout ═ true | false > andreplaceprogam ═ x;
for some users (regions or groups of users) to block off programs, blocking may be by cutting off or instead playing out an alternative program, code: if (Area in < blackout Area > or (User group in < blackout User group >) the n isBlackout ═ true; or substituted with program: if (Area in < blackout Area list >) or (User group in < blackout User group list >) the n isBlackout ═ true andtreprogram. The specific code implementation manner can be various, and the embodiment of the invention is not limited.
When the UMS and the program are injected into the CDN, the UMS transfers the shielding information isBlackout information of the program to the CDN, and the CDN uses an existing module or an extension module to parse the isBlackout information.
S202, the CDN receives a request for acquiring the program data sent by a user terminal, and the CDN determines user characteristic information of a user according to the request;
the CDN can acquire the carried user characteristic information from the request; the pre-stored user characteristic information can be obtained from the CDN according to the user identification information carried in the request; the CDN may also request to obtain corresponding user feature information from other network elements (e.g., a UMS, an EPG server, etc.) according to the user identification information carried in the request. The above steps S201 and S202 do not necessarily have a strict sequence relationship, and S202 may be executed first and then S201 may be executed.
S203, the CDN shields the program data sent to the user terminal when determining that the user characteristic information matches the shielding information of the program.
When a user requests the CDN to play through the terminal, the CDN determines that the attribute data of the program includes a shielding information field isBlackout, and then further shields the user from the specific program according to a comparison between a user characteristic attribute included in the isBlackout field and user characteristic information, that is, a specific program is not streamed for the blackout program, because the shielding program is not streamed and a black screen may be generated, the terminal user experience is not good, at this time, a replacement program may be played instead, and the replacement program information or the replacement program itself may be issued with the isBlackout information or may be preset by the CDN itself (that is, the replacement program is not set in the isBlackout information).
Specifically, the CDN detects that the program blackout is for the current user, and stops the current program stream to find an alternative program, which may be a vod (video On demand) program or a recorded program that exists in the CDN and is flexibly specified by the operator.
For the mask information described in a negative or negative manner, for example, "isonotbllackout," and "match" may refer to that, if the user characteristic information satisfies the condition of mask attribute description, the program is not masked for the user, and the matching logic may be flexibly set from the positive and negative aspects, which is not limited in the embodiment of the present invention.
The technical scheme of the embodiment of the invention is as follows: the method comprises the steps of expanding shielding information on metadata of IPTV unicast or OTT programs through UMS, supporting carrying user characteristic values of areas, user groups and the like, and carrying the shielding information when the programs and the program list are injected into the CDN. When a user selects a certain program, and a terminal requests the CDN, the CDN judges whether to shield certain specific programs for the user according to shielding information, and if so, the specified program does not flow (a replacing program can be broadcast instead); otherwise, the program is appointed to be played in a normal streaming mode. By the method of the embodiment of the invention, the flexible shielding of the program is realized on the CDN.
The embodiments of the present invention will be described in further detail below based on the common aspects of the present invention described above.
Referring to fig. 3, a flowchart of UMS distribution and program according to an embodiment of the present invention is shown:
s301, the operator creates a program through the UMS, and sets isBlackout information on the program.
S302, UMS notifies CDN to inject the program, carrying the isBlackout information of the program.
S303, the CDN stores the program and shielding information of the program, such as isBlackout information; of course, it may further include alternative program information.
Further, referring to steps S304 and S305, the UMS may further send user characteristic information to the CDN, where the user characteristic information includes an area, a user group, an interest group, and the like corresponding to the user identifier, and the CDN stores the user information, so as to facilitate subsequent acquisition and shielding of a specific program for the user.
By the method of the embodiment of the invention, the CDN can receive the program carrying the shielding information from the UMS, and can further obtain the user characteristic information of the user from the UMS and store the user characteristic information for subsequent shielding judgment.
Referring to fig. 4, a schematic flow chart of the terminal user initiating program watching according to the embodiment of the present invention is shown:
s401, the terminal user browses a channel or a program list through the user terminal and selects one to play.
S402, the terminal requests the CDN to play the program.
Note that: the steps that the terminal needs to request the EPG Server to perform service authentication and acquire the playing address are omitted, the step assumes that the information is already acquired, and then requests the CDN to perform playing, and optionally, the user terminal can acquire the user characteristic information in the interaction with the EPG Server.
S403, the CDN analyzes the isBlackout information of the program locally stored, and if the isBlackout information includes the user characteristic attribute, the CDN obtains the user characteristic information of the terminal user in a manner that may include:
according to the user identification, searching user characteristic information of the terminal user from user information stored by the terminal user; the user information stored on the CDN may be obtained from the UMS before or may be obtained from another service server;
after receiving the playing request, inquiring user characteristic information, such as an area, a user group and the like, of the current requesting user from the UMS according to the user identification in the request;
acquiring user characteristic information from a play request of a user terminal: the user terminal itself or the network element through which the play request passes may be configured with user characteristic information, when the play request reaches the CDN, the play request will have the user characteristic information that it obtained on the propagation path, and the CDN may obtain the user characteristic information from the request itself; in addition, from the start of the user clicking the program, it can be seen in step 402 that since user authentication is required to obtain the playing address, the request may first reach EPGserver, EPG server may return the user characteristic information to the playing terminal in the message returned to the user terminal, and the playing terminal sends the playing request carrying the user characteristic information to the CDN;
s404, the CDN judges whether the program needs to be shielded for the user according to the isBlackout information and the user characteristic information, and if yes, the blackout program is not outputted; otherwise, the flow is normal.
If the operator sets a blackout program replacement program, the CDN does not stream the blackout program, and instead, the CDN streams the replacement program; as for the way of playing the alternative program by the CDN, the foregoing embodiment of the present invention has been described, and details are not described here.
By the method of the embodiment of the invention, after receiving the play request of the user, the CDN can acquire the user characteristic information of the requesting user in various modes and compare the user characteristic information with the shielding information in the program data issued by the UMS to determine whether to shield the user with a specific program, thereby realizing the flexible shielding function of the program on the CDN.
The following describes an embodiment in which the CDN comprehensively considers the shielding information of the channel and the program to shield the user.
A channel is a carrier of a media stream, in a UMS system, the channel and a program are maintained respectively, and the UMS generally creates the channel first and maintains metadata of the channel; then, a plurality of programs are created under the channel, and the metadata is maintained, wherein the programs are content information transmitted in the media stream. Therefore, in the embodiment of the present invention, an administrator may also carry shielding information in metadata of a channel through the UMS and send the shielding information to the CDN, and the CDN may also refer to the methods in all the embodiments described above, and match the shielding information of the channel with user feature data of an access user to determine whether the user can access a specific channel, and the shielding information of the channel may further set a time limit to determine that the specific user can only access the specific channel or cannot access the specific channel at a specific time period. The sending and using of the shielding information of the channel and the shielding information of the program may be performed separately or in combination, and may be flexibly configured in the UMS or the CDN by a user (such as an operator), which is not limited in the embodiment of the present invention.
Generally, in the case of combined use, the CDN first uses the shielding information of the channel to match with the user characteristic information, and after confirming that the requesting user can access the specific channel, further determines whether the program in the channel allows the user to access; if it is determined that the user cannot access the channel based on the screening attributes of the channel, there is no need to match the screening information of the program.
The program distribution method provided by the embodiment of the invention can realize more flexible shielding control by further combining the shielding information of the channel.
