Fig. 1 is an interaction schematic diagram of a streaming media playing system provided by an embodiment of the present disclosure, where, as shown in fig. 1, the system includes a terminal and a server. The terminal is in communication connection with the server. Wherein:

the terminal is configured to: and sending a target playing request comprising the decryption resource information to the server. Wherein the decryption resource information characterizes the amount of resources available to the terminal for decryption processing. The target playing request is used for requesting to play the target streaming media.

The server is configured to: and determining stream media data matched with the decryption resource information from a stream media data set predetermined for the target stream media. Wherein, the consumption of decryption resources of the streaming media data in the streaming media data set is different. The above-described decryption resource consumption amount characterizes the amount of resources consumed for performing decryption processing on streaming media data. And returning the determined streaming media data to the terminal.

As shown in fig. 1, in step 101, the terminal sends a target play request including decryption resource information to the server.

In this embodiment, the terminal may send a target play request including decryption resource information to the server.

The decryption resource information may represent the amount of resources available to the terminal for decryption.

In some optional implementations of this embodiment, the decryption resource information may be determined based on at least one of:

The preset program may include one or more program statements. As an example, the preset program may be an arbitrary program; alternatively, the preset program may be used to obtain at least one of a usage rate of the cpu of the terminal, a remaining running space of the cpu of the terminal, remaining information of the network bandwidth of the terminal, network delay information of the terminal, and network jitter information of the terminal.

The decryption resource information may include at least one item described above, or the decryption resource information may be a result of a weighted sum of at least two items described above, for example.

It can be appreciated that in the above alternative implementation manner, the decryption resource information of the terminal is determined based on at least one item, so that the decryption capability of the terminal can be measured from a plurality of different angles, which is helpful for further reducing the occurrence probability of the phenomena of blocking, frame dropping, sound distortion and the like of the playing stream media of the terminal through the subsequent steps.

Alternatively, the decryption resource information may be core information (such as the number of cores, a core version, etc.) of the terminal.

The target playing request may be used for requesting to play the target streaming media. The target play request may be used to request to play any streaming media. The target streaming media may be streaming media requested to be played by the target play request.

The streaming media (streaming media) may be a technology and process of transmitting data in segments over the internet after compressing or not compressing a series of media data, and transmitting video and audio on the internet in real time for viewing.

In some optional implementations of this embodiment, before the sending, to the server, the target play request including the decryption resource information, the terminal may further acquire the decryption resource information at a preset frequency (for example, acquire the decryption resource information once every fixed time duration). On this basis, the terminal may perform the step 101 in the following manner, so as to send a target play request including decryption resource information to the server side: and sending the decryption resource information acquired by the terminal last time to the server.

It can be understood that in the above alternative implementation manner, by acquiring the decryption resource information according to the preset frequency, compared with the scheme that the decryption resource information is acquired after the target playing request is received, the speed of playing the target streaming media can be improved, and the decryption resource information acquired by the terminal last time is sent to the server, so that the decryption resource information for decrypting the streaming media can be more accurately acquired.

Optionally, the terminal may acquire the decryption resource information after receiving the target playing request.

In some application scenarios in the above alternative implementation manners, the terminal may acquire the decryption resource information according to a preset frequency in the following manner:

first, the thread is started at a preset frequency.

And then, acquiring decryption resource information according to the preset frequency by adopting the thread.

It can be understood that in the above application scenario, the decryption resource information is obtained by starting a new thread, so that the influence of obtaining the decryption resource information on other operations performed by the current terminal can be reduced.

In step 102, the server determines, from among a set of streaming data predetermined for the target streaming, streaming data that matches the decryption resource information.

In this embodiment, the server may determine, from a set of streaming media data predetermined for the target streaming media, streaming media data that matches the decryption resource information.

Wherein, the consumption of decryption resources of the streaming media data in the streaming media data set is different. The above-described decryption resource consumption amount characterizes the amount of resources consumed for performing decryption processing on streaming media data.

In some optional implementations of this embodiment, the server may perform the step 102 in the following manner, so as to determine streaming media data that matches the decryption resource information:

and if the resource quantity represented by the decryption resource information is smaller than the target decryption resource consumption quantity, determining the streaming media data corresponding to the target decryption resource consumption quantity as the streaming media data matched with the decryption resource information.

Wherein the target decryption resource consumption is: the minimum decryption resource consumption of the streaming media data in the streaming media data set.

The following correspondence may exist between the decryption resource consumption amount and the streaming media data (including the streaming media data for which the target decryption resource consumption amount corresponds to the target decryption resource consumption amount): the decryption resource consumption represents the amount of resources consumed for decrypting the streaming media data corresponding to the decryption resource consumption.

It can be understood that in the above alternative implementation manner, when the amount of resources represented by the decryption resource information is smaller than the target consumption amount of decryption resources, the streaming media data corresponding to the minimum consumption amount of decryption resources of the streaming media data in the streaming media data set can be determined, so that through the subsequent steps, less amount of resources can be consumed in the decryption process, and the playing of the target streaming media can be realized.

In some application scenarios in the above alternative implementation manner, the streaming media data corresponding to the target decryption resource consumption amount is unencrypted streaming media data. That is, the streaming media data corresponding to the target decryption resource consumption is the original streaming media data of the target streaming media data.

It can be understood that under the application scenario, the terminal can realize the playing of the target streaming media without decrypting the streaming media data.

Optionally, the server may also perform the step 102 in the following manner, so as to determine the streaming media data that matches the decryption resource information:

if the decryption resource information includes at least one of usage rate of a central processor of the terminal, remaining operation space of the central processor of the terminal, network bandwidth remaining information of the terminal, network delay information of the terminal, and network jitter information of the terminal, the usage rate of the central processor of the terminal required for decryption, the operation space of the central processor of the terminal required for decryption, network bandwidth information of the terminal required for decryption, network delay information of the terminal required for decryption, and network jitter information of the terminal, which are required for decryption, may be predetermined or predicted for each of the streaming media data in the streaming media data set accordingly, so that the streaming media data with the highest security degree of supporting decryption (i.e., the maximum consumption of decryption resources) by the terminal is used as the streaming media data matched with the above decryption resource information.

As an example, the streaming data that the terminal supports decryption includes streaming data that meets the following conditions:

the utilization rate of the central processing unit of the terminal is larger than that of the central processing unit of the terminal required by decrypting the streaming media data.

The remaining running space of the central processor of the terminal is larger than the running space of the central processor of the terminal required for decryption.

The network bandwidth remaining information of the terminal is larger than the network bandwidth information of the terminal required for decryption.

In step 103, the server returns the determined streaming media data to the terminal.

In this embodiment, the server may return the determined streaming media data to the terminal.

In step 104, the terminal plays the target streaming media based on the determined streaming media data.

In this embodiment, the terminal may play the target streaming media based on the determined streaming media data.

In some optional implementations of this embodiment, the terminal may perform the step 103 in the following manner, so as to play the target streaming media based on the determined streaming media data:

if the determined streaming media data is the streaming media data subjected to encryption processing, playing the streaming media data obtained by carrying out decryption processing on the determined streaming media data; and playing the determined streaming media data if the determined streaming media data is streaming media data which is not encrypted.

Here, the streaming media data may be decrypted using a decryption algorithm of an encryption algorithm corresponding to the determined streaming media data.

It can be appreciated that in the above alternative implementation manner, decryption or direct playing of the streaming media data may be implemented in a corresponding manner according to whether the streaming media data is encrypted.

Fig. 2 is an interaction schematic diagram of another streaming media playing system according to an embodiment of the present disclosure, where, as shown in fig. 2, the system includes a terminal and a server. The terminal is in communication connection with the server. Wherein:

The server is configured to: and determining a stream media data subset with the consumption of decryption resources being less than or equal to the resource quantity represented by the decryption resource information from the stream media data set which is preset for the target stream media. And then, determining the stream media data with the largest decryption resource consumption in the stream media data subset as the stream media data matched with the decryption resource information. Wherein, the consumption of decryption resources of the streaming media data in the streaming media data set is different. The above-described decryption resource consumption amount characterizes the amount of resources consumed for performing decryption processing on streaming media data. And returning the determined streaming media data to the terminal. At least part of the streaming media data in the streaming media data set corresponds to an encryption algorithm respectively. The single stream media data in the at least part of stream media data is encrypted by adopting an encryption algorithm corresponding to the single stream media data. The consumption of decryption resources of the streaming media data is positively correlated with the security of the encryption algorithm.

As shown in fig. 2, in step 201, the terminal transmits a target play request including decryption resource information to the server.

In this embodiment, the terminal may send a target play request including decryption resource information to the server. The decryption resource information characterizes the resource amount available for decryption processing by the terminal, and the target playing request is used for requesting to play the target streaming media.

In this embodiment, the implementation manner of step 201 may refer to step 101, which is not described herein.

In step 202, the server determines a subset of streaming media data whose consumption of decryption resources is less than or equal to the amount of resources represented by the decryption resource information from a set of streaming media data predetermined for the target streaming media.

In this embodiment, the server may determine, from a set of streaming media data predetermined for the target streaming media, a subset of streaming media data having a consumption of decryption resources less than or equal to a resource amount represented by the decryption resource information.

Wherein, the consumption of decryption resources of the streaming media data in the streaming media data set is different. The above-described decryption resource consumption amount characterizes the amount of resources consumed for performing decryption processing on streaming media data. At least part of the streaming media data in the streaming media data set corresponds to an encryption algorithm respectively. The single stream media data in the at least part of stream media data is encrypted by adopting an encryption algorithm corresponding to the single stream media data. The consumption of decryption resources of the streaming media data is positively correlated with the security of the encryption algorithm.

In some optional implementations of this embodiment, the decryption resource consumption amounts of the streaming media data in the at least part of streaming media data are arranged in order from small to large, and then form an arithmetic progression.

Here, each encryption algorithm in the preset encryption algorithm set may be used to encrypt the target streaming media, and then decrypt it, and calculate the consumption of decryption resources used for decrypting with each encryption algorithm. And then, selecting a plurality of decryption resource consumption amounts in an arithmetic series from the obtained decryption resource consumption amounts, and respectively corresponding to the streaming media data of the plurality of decryption resource consumption amounts. Therefore, the decryption resource consumption of the selected streaming media data can be arranged in an equal difference sequence from small to large.

It can be understood that in the above alternative implementation manner, the consumption of decryption resources of the streaming media data in the at least part of streaming media data is more uniformly distributed, so that the decryption requirements of each terminal on the streaming media data in different scenes of decryption resource information of the terminal can be met.

In step 203, the server determines the streaming media data with the largest consumption of decryption resources from the subset of streaming media data as the streaming media data matched with the decryption resource information.

In this embodiment, the server may determine, as the streaming media data that matches the decryption resource information, the streaming media data that has the greatest consumption of decryption resources from the subset of streaming media data.

In step 204, the server returns the determined streaming media data to the terminal.

In this embodiment, the implementation manner of step 204 may refer to step 103, which is not described herein.

In step 205, the terminal plays the target streaming media based on the determined streaming media data.

In this embodiment, the implementation manner of step 205 may refer to step 104 described above, and will not be described herein.

According to the streaming media playing system provided by the embodiment of the disclosure, the streaming media data subset with the decryption resource consumption less than or equal to the resource quantity represented by the decryption resource information is determined from the streaming media data set, and then the streaming media data with the maximum decryption resource consumption in the streaming media data subset is determined to be the streaming media data matched with the decryption resource information, so that the most safe streaming media data which can be used for decryption processing by the terminal is screened from the streaming media data set, and the security and fluency of streaming media playing are considered to a greater extent.

As an application scenario of the present embodiment, the present embodiment is exemplarily described below. It should be noted, however, that the embodiments of the present disclosure may have the features described below, but the following description does not limit the scope of the embodiments of the present disclosure.

In this application scenario, the server may encrypt the original streaming media (e.g., target streaming media) file by using encryption algorithms with different intensities (i.e., different security and different consumption of required decryption resources) respectively, so as to obtain a plurality of encrypted streaming media (i.e., streaming media data set predetermined for the target streaming media) files, and the client tests (e.g., acquires with a preset frequency) the decryption resource information of the device where the client is located in real time. When the decryption resource information is abundant, the server returns stream media data encrypted by a high-strength (i.e. high security and high consumption of the required decryption resource) encryption algorithm to the client; otherwise, the streaming media data encrypted by the encryption algorithm with relatively low intensity (i.e. low security and low consumption of required decryption resources) is returned to the client.

Here, the decryption resource metric may be made up of two parts: the time and network delay for the CPU to run the test program. The time the CPU runs the test program refers to the time the CPU spends running the test program mentioned later, and can be used to measure the speed of running the test program. Network latency refers to the time consumed by streaming media from a server to a client. The smaller the sum of the time the CPU runs the test program and the network delay, the more abundant the decryption resources are characterized; the streaming media data which consumes more CPU time and has higher security can be decrypted; otherwise, the streaming media data consuming less CPU and having lower security is decrypted.

Specifically, the server may be hardware or software, which may be responsible for generating streaming media data. The client may be hardware or software, and may be responsible for requesting streaming media data from the server to control video playing.

Here, the general law of encryption algorithms is: the better the security, the more resources are consumed in decryption (i.e., the amount of decryption resources consumed). Therefore, if the decryption resource information of the client for a certain period of time is short, the server returns the streaming media data with less decryption consumption resources to the client; otherwise, the streaming media data with more decryption consumption resources is returned to the client.

In addition, the server encrypts the original streaming media data (for example, the target streaming media) with different encryption algorithms, and stores the encrypted data in the server. When the encryption algorithm is selected, the decryption resource information consumed in decryption needs to be ensured to be different from each other. For example, the consumption may be evenly distributed from low to high. That is, the decryption resource consumption amounts of the streaming media data in the at least part of streaming media data are arranged in order from small to large and then are arranged in an arithmetic progression.

The client then starts an auxiliary thread at intervals to test the local decryption resource information. Before playing the streaming media, the streaming media data needs to be requested from the server, and the latest decryption resource information test result is carried when the streaming media data is requested.

Then, the server may select an appropriate encrypted streaming media data to send to the client according to the test result (i.e. the decryption resource information).

As an example, N encryption algorithms may be selected first, and the decryption resource consumption amounts of each algorithm are different from each other, for example, the decryption resource consumption amounts are distributed more uniformly from small to large. For example, three encryption algorithms may be selected: RC4 (Rivest Cipher 4) encryption algorithm, chaCha20 encryption algorithm, AES (Advanced Encryption Standard ) encryption algorithm. The security of the three encryption algorithms is from low to high, and the decryption overhead is also from low to high.

Specifically, firstly, the server encrypts the original streaming MEDIA by using N encryption algorithms to obtain N encryption results, and the N encryption results are assumed to be MEDIA respectively ₁ 、MEDIA ₂ 、……、MEDIA _n . Then, the server stores n+1 (the above N encryption results and MEDIA 0) pieces of streaming MEDIA data in the server. Wherein MEDIA ₀ Refers to the original stream media (i.e., the target stream media) that is not encrypted. Then, the client may start an auxiliary thread, and the thread runs a test program at intervals, where the test program is responsible for measuring the decryption resources of the device where the current client is located, and mainly includes the time and network delay of processing the test program by the CPU, and records the last measurement result (i.e. the above decryption resource information). Then, the client requests the streaming media data from the server, and the request (for example, the above-mentioned sending target playing request) needs to carry the last measurement result. Then, based on the measurement result, the server selects the streaming MEDIA with highest security under the condition of meeting the decryption resource _k Sending back to the client, if the decryption resources are very tight and cannot meet the decryption of any encryption algorithm, sending back to the MEDIA ₀ . Then, if the received streaming MEDIA is MEDIA _k The client decrypts the received MEDIA _k And restore it to MEDIA ₀ Then MEDIA is added ₀ Sending to a player for playing; if the received streaming MEDIA is MEDIA ₀ And directly sending to the player for playing.

Therefore, in the application scene, the decryption resource information of the playing device where the client is positioned can be measured in real time to select the encrypted streaming media, so that the time for starting playing the streaming media can be improved, namely the time for selecting to play a certain streaming media is shortened, and the time for actually starting playing the streaming media is shortened; and under the condition of not losing the security, the phenomena of streaming media blocking, frame loss and the like which possibly occur are reduced, and the use experience of a user is improved.
