Technical Field

Background

Currently, in the data transmission process between different devices (such as a terminal device and a server), it is necessary to determine the data transmission mode according to the network state. Taking the example of the server transmitting data to the terminal device, in the case of a poor network state (such as unstable wireless network signal or network congestion), the server may selectively discard some encoded frames to reduce the network load, so as to synchronize the data received by the terminal device with the data sent by the server. However, in the decoding process of the terminal device, if the subsequent frames still need to use the discarded frames as reference frames, the decoding may fail. In this case, the server may perform data retransmission, and the terminal device may still fail to decode, resulting in low decoding efficiency.

Cloud game technology enables light-end devices (thin clients) with relatively limited graphics processing and data computing capabilities to run high-quality games. In a cloud game scene, a game is not executed at a game terminal of a player, but is executed in a cloud server, the cloud server renders the game scene into a video and audio stream, and the video and audio stream is transmitted to the game terminal of the player through a network. The game terminal of the player does not need to have strong graphic operation and data processing capacity, and only needs to have basic streaming media playing capacity and capacity of acquiring input instructions of the player and sending the input instructions to the cloud server.

Cloud Computing Education (CCEDU) refers to an education platform service based on cloud computing business model application.

The cloud conference is an efficient, convenient and low-cost conference form based on a cloud computing technology. A user can share voice, data files and videos with teams and clients all over the world quickly and efficiently only by performing simple and easy-to-use operation through an internet interface, and complex technologies such as transmission and processing of data in a conference are assisted by a cloud conference service provider to operate.

Cloud social interaction (cloud social) is a virtual social application mode of internet of things, cloud computing and mobile internet interactive application, aims to establish a famous resource sharing relationship map, and further develops network social interaction, and is mainly characterized in that a large number of social resources are uniformly integrated and evaluated to form a resource effective pool to provide services for users as required. The more users that participate in the sharing, the greater the value of the utility that can be created.

Optionally, the data processing method provided in the embodiment of the present application may specifically relate to one or more of cloud computing, cloud storage, and a cloud database in the cloud technology. For example, the target data can be encoded through cloud computing, or the test encoding data configured with the long-acting reference frame is acquired from a cloud database, or the encoded target data is stored through cloud storage.

Among them, cloud computing (cloud computing) is a computing mode that distributes computing tasks over a resource pool formed by a large number of computers, so that various application systems can acquire computing power, storage space, and information services as needed. The network that provides the resources is referred to as the "cloud". Resources in the "cloud" appear to the user as being infinitely expandable and available at any time, available on demand, expandable at any time, and paid for on-demand.

A distributed cloud storage system (hereinafter, referred to as a storage system) refers to a storage system that integrates a large number of storage devices (storage devices are also referred to as storage nodes) of different types in a network through application software or application interfaces to cooperatively work by using functions such as cluster application, grid technology, and a distributed storage file system, and provides a data storage function and a service access function to the outside.

Database (database), which can be regarded as an electronic file cabinet-a place for storing electronic files in short, a user can add, query, update, delete, etc. to data in files. A "database" is a collection of data that is stored together in a manner that can be shared by multiple users, has as little redundancy as possible, and is independent of the application.

Fig. 1 is a block diagram of a data processing system according to an embodiment of the present disclosure. The data processing system may comprise a terminal device 101 and a server 102. The terminal device 101 may be configured to receive and respond to a probe request of long-acting reference frame capability from the server 102 to obtain test encoding data configured with a long-acting reference frame, and decode the test encoding data based on the long-acting reference frame to obtain a decoding result, so as to send probe information to the server 102 based on the decoding result to indicate whether the terminal device 101 has a capability of successfully decoding data configured with the long-acting reference frame.

The long-acting reference frame refers to a coded frame which is referred by frames with the quantity larger than a preset quantity threshold value in the coded data to be tested in the decoding process. By the above method, under the condition that the terminal device 101 has the capability of successfully decoding the data configured with the long-acting reference frame, the terminal device 101 may receive the encoded target data including the long-acting reference frame from the server 102, and decode the encoded target data based on the long-acting reference frame in the encoded target data to obtain the target data, so that the terminal device 101 may use the long-acting reference frame as the reference frame in the decoding process to improve the decoding efficiency, and may also avoid decoding errors caused by the terminal device 101 using the short-acting reference frame as the reference frame, thereby improving the accuracy of decoding.

The server 102 may be configured to send a probe request of long-acting reference frame capability to the terminal device 101, and receive probe information sent by the terminal device 101 in response to the probe request, so that the server 102 obtains whether the terminal device 101 has a capability of successfully decoding data configured with a long-acting reference frame, and thus determines whether to encode using an encoding manner including the long-acting reference frame according to the capability of the terminal device 101. The server 102 may be further configured to, under the condition that the detection information indicates that the terminal device 101 has the capability of successfully decoding the data configured with the long-acting reference frame, encode target data to obtain encoded target data including the long-acting reference frame, and send the encoded target data to the terminal device 101, so that the terminal device 101 may use the long-acting reference frame as the reference frame in a process of decoding the encoded target data to improve decoding efficiency, and may also avoid a decoding error caused by the terminal device 101 using the short-acting reference frame as the reference frame, thereby improving decoding accuracy.

The Terminal 101 may also be referred to as a Terminal (Terminal), a User Equipment (UE), a client, an access Terminal, a subscriber unit, a mobile device, a user Terminal, a wireless communication device, a user agent, or a user equipment. The terminal device may be, but is not limited to, a smart home appliance, a handheld device (e.g., a smart phone, a tablet computer) with a wireless communication function, a computing device (e.g., a Personal Computer (PC), a vehicle-mounted terminal, a smart voice interaction device, a wearable device, or other smart devices, etc.).

The server 102 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, cloud function, cloud storage, web service, cloud communication, middleware service, domain name service, security service, CDN, and big data and artificial intelligence platform, and the like, but is not limited thereto. The terminal device 101 and the server 102 may be directly or indirectly connected through wired or wireless communication, and the present application is not limited thereto.

It has been found that some current terminal devices do not have the capability to successfully decode data configured with long-term reference frames. If the server directly uses the coding mode comprising the long-acting reference frame for coding, and sends the coded data containing the long-acting reference frame to the terminal equipment. Assuming that the terminal device does not have the capability to successfully decode the data configured with the long-acting reference frame, the terminal device decodes the encoded data in the manner of the short-acting reference frame, resulting in a decoding failure. Based on this, the technical solution of the embodiment of the present application is provided, and specifically, a server sends a probe request of a long-acting reference frame capability to a terminal device, and receives probe information sent by the terminal device in response to the probe request, so that the server obtains whether the terminal device has a capability of successfully decoding data configured with a long-acting reference frame, and determines whether to encode using an encoding method including the long-acting reference frame according to the capability of the terminal device.

Specifically, the terminal device is configured with a hardware decoder, and the terminal device decodes the encoded data through the hardware decoder, but the functions of the hardware decoders provided by different manufacturers are inconsistent, for example, part of the hardware decoder does not provide support for the long-term reference frame characteristics, that is, the hardware decoder cannot identify the long-term reference frame, and only decodes the encoded data in the manner of the short-term reference frame. For a terminal device configured with such a hardware decoder, the terminal device may be considered to be incapable of successfully decoding data configured with a long-term reference frame.

Referring to fig. 2, fig. 2 is a schematic flow chart of a data processing method according to an embodiment of the present disclosure. The data processing method can be applied to the data processing system shown in fig. 1, and is executed by the terminal device and the server, and specifically can be executed by a processor of the terminal device and a processor of the server. The data processing method comprises the following steps:

s201, a server sends a detection request of long-acting reference frame capability to terminal equipment; accordingly, the terminal device receives a probe request for long term reference frame capability from the server.

Wherein the long-term reference frame capability probe request can be used for detecting whether the terminal device has the capability of successfully decoding the data configured with the long-term reference frame. That is, the server may determine whether the terminal device can successfully decode the data configured with the long-acting reference frame by transmitting the probe request to the terminal device.

Note that the "probe request" is only a name used in the embodiment of the present application, and the name does not limit the embodiment of the present application. Alternatively, the "probe request" may also be referred to as a "detection request", a "test request", or an "acknowledgement request", and the present application is not limited thereto.

S202, the terminal equipment responds to the detection request to acquire the test coding data configured with the long-acting reference frame, and decodes the test coding data based on the long-acting reference frame.

It should be noted that, after the terminal device receives the probe request of the long-acting reference frame capability from the server, the terminal device may start the probe process of the long-acting reference frame capability in response to the probe request to determine whether itself can successfully decode the data configured with the long-acting reference frame.

Specifically, the terminal device may obtain the test coding data configured with the long-acting reference frame, and decode the test coding data based on the long-acting reference frame, so as to determine whether the terminal device can successfully decode the data configured with the long-acting reference frame according to the decoding result. The test encoding data may be sent to the terminal device by the server, for example, the test encoding data may be carried in a probe request sent by the server. Optionally, the test encoding data may also be pre-stored in the terminal device, which is not limited in this application.

The long-acting reference frame refers to a coded frame which is referred by frames with the quantity larger than a preset quantity threshold value in the coded data to be tested in the decoding process. The preset number threshold may be a value preset by the terminal device or the server, or may be a default value, which is not limited in this application. For example, assuming that the test encoding data has 15 frames and the preset number threshold is 10 frames, the encoding frame referred to by the 12 frames of test encoding data in the decoding process can be determined as the long-acting reference frame. That is, in the decoding process, the long-term reference frame may be decoded by a frame greater than a preset number threshold as a reference frame. The preset number threshold is 10 frames, which is only used for example and does not limit the present application.

Optionally, the coded frames referred to by the frames in the coded data under test whose number is less than or equal to the preset number threshold in the decoding process may be regarded as short-term reference frames. For example, assuming that the test coded data has 15 frames and the preset number threshold is 10 frames, the coded frame referred to by 8 frames of test coded data in the decoding process can be determined as a short reference frame. That is, in the decoding process, the short-lived reference frame may be decoded as a reference frame by a frame less than or equal to a preset number threshold.

In one implementation, the storage duration of the long-acting reference frame in the reference frame buffer may be longer than a preset storage duration. Optionally, the storage duration of the short-lived reference frame in the reference frame buffer may be less than or equal to the preset storage duration. The preset storage duration may be preset by the terminal device or the server, or may be set by default by the system, which is not limited in this application.

It can be understood that, since the long-term reference frame can be used as a reference frame by a number of frames greater than a preset number threshold, that is, the long-term reference frame can be referred to by a larger number of encoded frames, the long-term reference frame cannot be easily deleted, so as to avoid causing decoding errors of the encoded frames that need to refer to the long-term reference frame. Therefore, in the reference frame buffer, the storage duration of the long-acting reference frame may be longer than the preset storage duration. That is, long-term reference frames may remain in the reference frame buffer for long periods of time.

Optionally, since the short-lived reference frames may be used as reference frames by frames whose number is less than or equal to the preset number threshold, that is, the short-lived reference frames may be referred to by a smaller number of encoded frames, some short-lived reference frames may be selectively deleted in case of network congestion or unstable network signals, so as to reduce the pressure of data transmission, thereby enabling data transmission between the terminal device and the server to be consistent.

For example, assuming that the preset storage duration is 24h, in the reference buffer, the storage duration of the long-term reference frame may be greater than 24h, and the storage duration of the short-term reference frame may be less than or equal to 24h. The preset storage time period of 24h is only for example and is not limited to the application.

S203, if the terminal equipment successfully decodes the test coding data configured with the long-acting reference frame, the terminal equipment generates a decoding result used for indicating the terminal equipment to successfully decode the test coding data.

The decoding result can be used for indicating whether the terminal equipment successfully decodes the test coded data. That is, the decoding result may indicate that the terminal device successfully decoded the test encoded data, or may indicate that the terminal device unsuccessfully decoded the test encoded data. Specifically, the terminal device decodes the test coded data based on the long-acting reference frame, and may obtain the following decoding results:

decoding result one:

and if the terminal equipment acquires the error code in the decoding process, generating a decoding result for indicating that the terminal equipment does not successfully decode the test coded data. The error code may be returned to the terminal device through an Application Programming Interface (API). It should be noted that, if the terminal device acquires the error code in the decoding process, it may be indicated that the terminal device fails to successfully decode the test coded data configured with the long-acting reference frame, that is, the terminal device does not support the long-acting reference frame setting. Further, if the terminal device obtains the correct code in the decoding process, it cannot be said that the terminal device can successfully decode the test coded data configured with the long-acting reference frame, and further judgment needs to be performed on the decoding result. Optionally, specific content of the error code or the correct code may be preset by the terminal device or the server, or may be set by default by the system, which is not limited in this application.

And a second decoding result:

and if the terminal equipment does not acquire the feedback data after the preset time length from the beginning of decoding, generating a decoding result for indicating that the terminal equipment does not successfully decode the test coded data. Wherein, the feedback data can comprise error codes, correct codes, test decoding data and other data; the test decoding data may be data obtained by decoding the test encoding data based on the long-acting reference frame by the terminal device. The preset duration may be preset for the terminal device or the server, or may be default set for the system, which is not limited in this application.

That is, after the preset duration elapses from the start of decoding, if the terminal device does not acquire any feedback data, it may be stated that the terminal device fails to decode the test coded data configured with the long-acting reference frame, that is, the terminal device does not support the long-acting reference frame setting. For example, assuming that the preset time duration is 15ms, if the terminal device does not acquire any feedback data after 15ms elapses from the start of decoding, it can also be understood that the terminal device is in a stuck state, and a decoding result indicating that the terminal device has not successfully decoded the test coded data is generated. Further, if the terminal device acquires the feedback data after the preset time period elapses from the start of decoding, it cannot be said that the terminal device can successfully decode the test coded data configured with the long-acting reference frame, and further determination of the decoding result is required.

In one embodiment, if the terminal device does not acquire the test decoding data after a preset time period elapses from the start of decoding, a decoding result indicating that the terminal device has not successfully decoded the test encoding data is generated. That is, after the preset time period has elapsed since the start of decoding, even if the terminal device acquires the correct code or other data, if the test decoding data is not acquired, the terminal device still generates a decoding result indicating that the terminal device has not successfully decoded the test encoded data. Further, if the terminal device acquires the test decoding data after a preset time period from the beginning of decoding, it can only indicate that the decoding process is normally completed, and it cannot indicate that the terminal device can successfully decode the test coding data configured with the long-acting reference frame, and further determination needs to be performed on the decoding result.

And a third decoding result:

under the condition that the terminal equipment acquires the test decoding data, the terminal equipment can compare the test decoding data with the test data, and if the test decoding data is matched with the test data, a decoding result for indicating the terminal equipment to successfully decode the test encoding data is generated; and if the test decoding data is not matched with the test data, generating a decoding result for indicating that the terminal equipment does not successfully decode the test encoding data. The test coding data is obtained by coding the test data. That is, if the terminal device acquires the test decoding data, the data obtained by decoding the test encoding data (i.e., the test decoding data) may be compared with the original data (i.e., the test data) to determine whether the test encoding data is successfully decoded, so as to obtain the decoding result.

In one implementation, the terminal device may calculate an MD5Message-Digest Algorithm (MD 5) value of the test decoded data, compare the MD5 value with a reference value, and if the MD5 value is the same as the reference value, the terminal device determines that the test decoded data matches the test data, that is, generates a decoding result indicating that the terminal device successfully decodes the test encoded data; and if the md5 value is not the same as the reference value, the terminal device determines that the test decoding data does not match the test data, i.e. generates a decoding result indicating that the terminal device has not successfully decoded the test encoded data. The reference value refers to an md5 value of the test data, where the md5 value may be a character string pre-stored in the terminal device, and the application is not limited thereto. Since the md5 value corresponding to each data is unique, that is, if the md5 value of the test decoding data is the same as the md5 value (i.e. the reference value) of the test data, it can be said that the test decoding data matches the test data, that is, the terminal device successfully decodes the test encoding data.

Optionally, if a decoding result indicating that the terminal device has not successfully decoded the test coded data is generated, which indicates that the terminal device cannot decode the coded frame including the long-acting reference frame, the terminal device may empty buffered data (for example, the test coded data, the feedback data, and the like) involved in the detection process of the long-acting reference frame capability, so as to prepare for subsequent decoding of the coded frame not including the long-acting reference frame.

It should be noted that, in the embodiment corresponding to fig. 2, the terminal device successfully decodes the test coded data configured with the long-acting reference frame, and generates a decoding result (i.e., the decoding result three) for instructing the terminal device to successfully decode the test coded data, which is not limited in this application.

In one implementation, a terminal device may be configured with a hardware decoder; the terminal equipment can call a hardware decoder, and the test coding data are decoded based on the long-acting reference frame to obtain a decoding result. Wherein the decoding result can be used to indicate whether the hardware decoder successfully decoded the test coded data.

It should be noted that, in the case that the terminal device is configured with a hardware decoder, the terminal device may invoke the hardware decoder to perform the above-mentioned detection procedure of the long-acting reference frame capability, so as to confirm whether the hardware decoder has the capability of successfully decoding the data configured with the long-acting reference frame. That is, the terminal device may invoke the hardware decoder to obtain the test coding data configured with the long-acting reference frame, and invoke the hardware decoder to decode the test coding data based on the long-acting reference frame to obtain a decoding result.

Specifically, if the hardware decoder obtains the error code in the decoding process, a decoding result indicating that the hardware decoder has not successfully decoded the test coded data may be generated; if the hardware decoder does not acquire the feedback data after the preset duration from the beginning of decoding, a decoding result for indicating that the hardware decoder does not successfully decode the test coded data can be generated; under the condition of acquiring the test decoding data, the hardware decoder can compare the test decoding data with the test data, and if the test decoding data is matched with the test data, a decoding result for indicating the hardware decoder to successfully decode the test encoding data is generated; if the test decoded data and the test data do not match, a decoding result indicating that the hardware decoder did not successfully decode the test encoded data is generated.

Optionally, if a decoding result indicating that the hardware decoder did not successfully decode the test coded data is generated, which indicates that the hardware decoder cannot decode the coded frame including the long-acting reference frame, the terminal device may reset the hardware decoder, that is, clear buffer data (e.g., the test coded data, the feedback data, and the like) of the hardware decoder, so that the reset hardware decoder may decode the coded frame not including the long-acting reference frame in a subsequent decoding process.

Wherein the sounding information may be used to indicate whether the terminal device has the capability to successfully decode data configured with long-term reference frames. That is, the terminal device may transmit, to the server, probe information indicating that the terminal device has a capability of successfully decoding data configured with the long-term reference frame, based on a decoding result of successfully decoding the test encoded data; alternatively, the terminal device may transmit, to the server, probe information indicating that the terminal device does not have the capability of successfully decoding the data configured with the long-term reference frame, based on a decoding result of unsuccessfully decoding the test-coded data.

S205, the server adopts a coding mode comprising the long-acting reference frame to code the target data, and coded target data comprising the long-acting reference frame is obtained.

It should be noted that, in a case that the probe information acquired by the server indicates that the terminal device has the capability of successfully decoding the data configured with the long-acting reference frame, the server may encode the target data in an encoding manner including the long-acting reference frame to obtain encoded target data including the long-acting reference frame.

Optionally, when the detection information acquired by the server indicates that the terminal device does not have the capability of successfully decoding the data configured with the long-acting reference frame, the server may encode the target data in an encoding manner including the short-acting reference frame to obtain encoded target data including the short-acting reference frame.

S206, the server sends the encoded target data to the terminal equipment; correspondingly, the terminal equipment receives the coded target data from the server.

After the server codes the coded target data including the long-acting reference frame, the coded target data including the long-acting reference frame can be sent to the terminal device, so that the terminal device can decode the coded target data based on the long-acting reference frame in the coded target data in the decoding process to obtain the target data, and the decoding efficiency is improved.

In one implementation, in a case that the detection information indicates that the terminal device does not have the capability of successfully decoding the data configured with the long-acting reference frame, the server may encode the target data to obtain encoded target data including the short-acting reference frame; and the server sends the encoded target data comprising the short-term reference frame to the terminal equipment, so that the terminal equipment decodes the encoded target data comprising the short-term reference frame based on the short-term reference frame to obtain the target data. The short-term reference frame refers to a coded frame which is referred to by frames with the number smaller than or equal to a preset number threshold in the coded data to be tested in the decoding process.

It can be understood that, if the terminal device does not have the capability of successfully decoding the data configured with the long-term reference frame, the server may encode the target data in an encoding manner that includes the short-term reference frame, so as to obtain encoded target data that includes the short-term reference frame, so that the terminal device may decode the encoded target data that includes the short-term reference frame, and further obtain the target data.

And S207, the terminal equipment decodes the coded target data based on the long-acting reference frame in the coded target data to obtain the target data.

Optionally, under the condition that the terminal device does not have the capability of successfully decoding the data configured with the long-acting reference frame, the encoded target data including the short-acting reference frame from the server may be received, and the encoded target data may be decoded based on the short-acting reference frame in the encoded target data, so as to obtain the target data.

In the embodiment of the application, the server sends the detection request of the long-acting reference frame capability to the terminal device, so that the terminal device can respond to the detection request to obtain the test coding data configured with the long-acting reference frame, and decode the test coding data based on the long-acting reference frame to obtain the decoding result, so that the server sends the detection information indicating whether the terminal device has the capability of successfully decoding the data configured with the long-acting reference frame or not based on the decoding result, so that the server codes the target data to obtain the coded target data comprising the long-acting reference frame under the condition that the server receives the capability indicating that the terminal device has the capability of successfully decoding the data configured with the long-acting reference frame, and the decoding efficiency is further improved.
