Description
Technical Field
The invention relates to the technical field of live broadcast, in particular to a live broadcast viewing method, a live broadcast viewing system, a live broadcast viewing medium and a live broadcast viewing device for streaming media.
Background
Live television is taken as a traditional audio and video service in the market, and is gradually transferred to the internet from a traditional cable television channel in recent years, and a powerful streaming media system is required to be used as a service support when the live television is played on the internet, and the trial watching system related to the invention is a part of the streaming media system. For some premium channels of live television, service providers often adopt paid services, and these paid channels are often expected to enable users to experience premium content for free and then make subsequent paid purchases.
At present, live broadcast watching trial service of the internet television skips to a live broadcast address mainly through an APP upper-layer interface, and then duration of the watching trial behavior is controlled by limiting play time at an APP end. In order to attract the end user to the greatest extent, the user is not required to provide authentication, such as a telephone number or a WeChat, at the time of the trial. But this gives the hotlink the opportunity to sniff the application layer interface by way of network packet-grabbing, emulating an end-user trying to see the request. And because there is no user authentication process, the application layer interface can not distinguish real users from simulated users, the hotlink thief can directly access the live broadcast address with the hotlink, although a CDN (content delivery network) manufacturer provides hotlink service, because the expiration time of the traditional hotlink is often more than 8 hours, the hotlink thief can complete the circulating hotlink process by acquiring the playlist again before the link is invalid, and then steal the corresponding live broadcast resources almost without cost. As is well known, the largest cost of video service on the internet is CDN cost, if a live broadcast source is circularly stolen because a play interface is cracked when a user tries to watch the live broadcast, a huge loss is undoubtedly caused to a streaming media service provider, and a playlist in which the above anti-theft chain scenes are docked is a live broadcast address, the expiration time of the address highly depends on the configuration of the CDN, when a chain stealing situation occurs, if the CDN decreases the expiration time in batches, the live broadcast experience of the user is affected, but if the expiration time is separately configured for a channel trying to watch the live broadcast, when multiple channels try to watch the CDN, the live broadcast experience is abnormally complicated and inflexible, and the cost is correspondingly increased.
Therefore, it is desirable to solve the problem of how to prevent the live broadcast source from being stolen due to the hacking of the playing interface when the user tries to watch the live broadcast source.

The live broadcast trial viewing method, the live broadcast trial viewing system, the live broadcast trial viewing medium and the live broadcast trial viewing device are used for preventing a live broadcast source from being circularly stolen due to the fact that a playing interface is cracked when a user tries to view the live broadcast source.
As shown in fig. 1a, in an embodiment, the live viewing method of streaming media of the present invention includes the following steps:
step S11, a trial viewing request sent by the client is obtained through the time processing module, the trial viewing request comprises a start time and a trial viewing duration, whether the time difference between the start time and the current time is smaller than or equal to a first preset time or not is judged, when the time difference is larger than the first preset time, access prohibition information is sent to the client, when the time difference is smaller than or equal to the first preset time, whether the trial viewing duration is within a first preset duration range or not is judged, when the time difference is not within the first preset duration range, the trial viewing duration is reset, and when the time difference is within the first preset duration range, the trial viewing request is sent to the multitask processing module.
Step S12, the task processing module determines whether the trial viewing request is a first trial viewing request, establishes a task and a corresponding ID for the trial viewing request when the first trial viewing request is made, stores the task in a task list, queries whether a task exists in the task list when the first trial viewing request is not made, sends information for prohibiting access to the client when no task exists, determines whether a trial viewing end time of the task is reached when a task exists, recovers the ID of the task when the trial viewing end time is reached, sends an endlist generation instruction to the playlist return module, and sends the task to the playlist return module when the trial viewing end time is not reached.
And step S13, generating a video file based on the video file generation rule through the playlist return module, writing the video file information of the video file conforming to the trial viewing rule into a playlist, and returning the playlist to the client.
As shown in fig. 1b, in an embodiment, the live viewing method of streaming media of the present invention includes the following steps:
the method comprises the steps of obtaining a trial viewing request sent by a client through a time processing module, wherein the trial viewing request comprises start time and trial viewing duration. The start time refers to a timestamp of the current time of the client, namely the current time of the client, and the viewing duration refers to the viewing time length of the live broadcast viewing request viewed by the user.
And judging whether the time difference between the starting time and the current time is less than or equal to a first preset time. Specifically, the first preset time is 30 seconds. The current time refers to the time of the live broadcast test system of the streaming media where the time processing module is located. Namely, whether the absolute value of the time difference between the start time and the current live streaming media viewing trial system time is less than or equal to 30 seconds is judged. The validity of the request for test viewing can only be ensured within a certain time difference. Because internet video playback devices are various and have OTT boxes or smart televisions and the like, the timestamps of the clients are not completely consistent with the timestamp of the streaming media live broadcast viewing system, and therefore redundant time processing is added to the streaming media live broadcast viewing system to ensure the effectiveness of viewing. If the absolute value of the difference between the timestamp transmitted by the client and the timestamp of the streaming media live broadcast viewing system is less than or equal to 30s, the range is considered to be a reasonable range, and viewing services are provided for the client. Therefore, a certain error time is allowed to exist, and the validity of the trial-view request is ensured.
And when the time is longer than the first preset time, sending access prohibition information to the client. The prohibited access information includes, but is not limited to, being sent to the client in 403.
And when the trial viewing time length is less than or equal to a first preset time, judging whether the trial viewing time length is in a first preset time length range, and resetting the trial viewing time length when the trial viewing time length is not in the first preset time length range. For example, the first preset time is 1 to 10 minutes, and if the trial-and-look time period is not within the first preset time period range, the trial-and-look time period is reset to the preset trial-and-look time period, for example, 8 minutes. In order to ensure the trial viewing effect and prevent continuous steal, secondary limitation is made on the live streaming media trial viewing system, the trial viewing duration is only provided for 1-10 minutes, and the trial viewing duration can be reset to the range even if the client requests to exceed the range.
The trial view request occurs to the multitask processing module when within a first preset time range. And when the time difference between the start time and the current time is less than or equal to a first preset time and the trial viewing time is within a first preset time range, sending the trial viewing request to the multitask processing module.
As shown in fig. 1c, in an embodiment, the live viewing method of streaming media of the present invention includes the following steps:
and judging whether the trial viewing request is a first trial viewing request or not through the task processing module. After the streaming media live-broadcast viewing system is deployed in a large scale, the request amount of viewing requests is large, so that multitask processing is needed. And judging whether the trial viewing request is the first trial viewing request or not means whether the trial viewing request is the same request or not, because the client continuously sends the trial viewing request to the streaming media live viewing system every 6 seconds within the trial viewing duration of the same request, and the streaming media live viewing system feeds back trial viewing content.
And establishing a task and a corresponding ID for the test-view request when the test-view request is the first test-view request. I.e. one is that the request for a look-through corresponds to one task and ID.
And storing the task to a task list. The task list includes, but is not limited to, a red-black tree data structure.
And inquiring whether a task exists in the task list when the first trial viewing request is not, and sending access prohibition information to the client when the task does not exist. In the subsequent trial viewing process, the corresponding task is inquired according to the ID, the content of the trial viewing request is continuously updated, when the task does not exist and is not the first trial viewing request, an error is indicated, the corresponding trial viewing task does not exist, and therefore the access prohibition information (403) is returned to the client.
And judging whether the trial viewing end time of the task is reached or not when the task exists, recovering the ID of the task and sending a generated endlist instruction to a playlist returning module when the trial viewing end time is reached, and sending the task to the playlist returning module when the trial viewing end time is not reached. If the trial viewing request is expired, the streaming media of the task recovering the ID is broadcasted to the trial viewing system resource, and the task of accessing the ID again is returned 403 to the client. And when the trial viewing ending time is just reached, recovering the ID of the task and sending a generated endlist instruction to the playlist returning module, namely informing the playlist returning module that the trial viewing task has reached the trial viewing ending time, needing to end trial viewing and informing the client. The endlist instruction is an instruction for informing the client of finishing the trial viewing. The M3U8 generation module shown in fig. 1c is a playlist return module.
Specifically, the streaming media live viewing system example accessed by the client is as follows.
#EXTM3U
#EXT-X-STREAM-INF:BANDWIDTH＝1300000,RESOLUTION＝1024x576
1300.m3u8？session＝0
As shown in fig. 1d, in an embodiment, the live viewing method of streaming media of the present invention includes the following steps:
and generating a video file based on a video file generation rule through the playlist returning module, writing the video file information of the video file conforming to the trial viewing rule into a playlist, and returning the playlist to the client. Ts is a format suffix of a video, similar to MP4, etc. And the video file is a video slice.
Specifically, the examination rule is that: the method comprises the steps that a trial viewing request corresponding to a video file accords with trial viewing rules, the trial viewing request comprises start time and trial viewing duration, the start time meets the condition that the time difference between the start time and the current time is less than or equal to first preset time, and the trial viewing duration meets the condition that the trial viewing duration is within a first preset duration range.
Specifically, a video file at the current time of the task is inquired from a source station live broadcast slice list through the playlist returning module, when the video file at the current time is not inquired, a video file closest to the current time is obtained and written into a playlist (M3U8 is the playlist), when the video file at the current time is inquired, the video file at the current time is written into the playlist, whether the task is ended or not is judged through the starting time and the trial viewing time length, when the task is not ended, the playlist is returned to the client, when the task is ended, an endlist instruction is added behind the playlist, and when the task is ended, the playlist, the endlist instruction and the successful return information (200) are returned to the client. The invention provides a new trial viewing interface at the streaming media layer of the source station, because the trial viewing length is controllable and configurable at the height of the streaming media live broadcast trial viewing system, even if the upper layer interface is cracked, the streaming media live broadcast trial viewing system can automatically stop playing according to the built-in expiration time within the expiration time of the anti-theft chain, because of the characteristics of the HLS streaming media protocol, once the playing is exited after expiration, the M3U8 for trial viewing is requested again, because of the time difference of slicing, the fluency of live broadcast video can be greatly reduced, and the anti-theft chain is meaningless, so that the possibility of stolen chain can be effectively reduced, and the loss of a television live broadcast service provider can be reduced.
Specifically, the example of M3U8 at the end of the trial is as follows:
