Background

Currently, in the process of data transmission between different devices (such as a terminal device and a server), a data transmission manner needs to be determined according to a network state. Taking the example of the server transmitting data to the terminal device, in the case of poor network conditions (such as unstable wireless network signals or network congestion), the server may selectively discard some encoded frames to relieve the network burden, so that the data received by the terminal device is synchronized with the data sent by the server. However, in the decoding process of the terminal device, if the subsequent frames still need to use those discarded frames as reference frames, decoding failure may occur. In this case, the server may retransmit the data, and the terminal device may still fail decoding, resulting in lower decoding efficiency.

Cloud gaming (close gaming), which may also be referred to as game on demand, is an online gaming technology based on cloud computing technology. Cloud gaming technology enables lightweight devices (thin clients) with relatively limited graphics processing and data computing capabilities to run high quality games. In a cloud game scene, the game is not run in a player game terminal, but is run 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 player game terminal through a network. The player game terminal does not need to have strong graphic operation and data processing capability, and only needs to have basic streaming media playing capability and the capability of acquiring player input instructions and sending the player input instructions to the cloud server.

The more users that participate in the sharing, the greater the utility value 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 cloud databases in cloud technologies. For example, the method can encode target data through cloud computing, or acquire test encoded data configured with a long-acting reference frame from a cloud database, or store the encoded target data 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, enabling various application systems to 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 are infinitely expandable in the sense of users, and can be acquired at any time, used as needed, expanded at any time and paid for use as needed.

Cloud storage (cloud storage) is a new concept that extends and develops in the concept of cloud computing, and a distributed cloud storage system (hereinafter referred to as a storage system for short) refers to a storage system that integrates a large number of storage devices (storage devices are also referred to as storage nodes) of various types in a network to work cooperatively through application software or application interfaces through functions such as cluster application, grid technology, and a distributed storage file system, so as to provide data storage and service access functions for the outside.

The database (database), which can be simply referred to as an electronic filing cabinet, is a place where electronic files are stored, and a user can perform operations such as adding, querying, updating, deleting and the like on data in the files. A "database" is a collection of data stored together in a manner that can be shared with multiple users, with as little redundancy as possible, independent of the application.

With reference to FIG. 1, an architecture diagram of a data processing system is provided in an embodiment of the present application. 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 from the server 102 for the capability of the long-acting reference frame, to obtain test encoded data configured with the long-acting reference frame, and decode the test encoded 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 the capability of successfully decoding the data configured with the long-acting reference frame.

The long-acting reference frame refers to the coded frame of which the number of frame references in the tested coded data is larger than a preset number threshold in the decoding process. By the above manner, the terminal device 101 can receive the encoded target data including the long-acting reference frame from the server 102 under the condition of having the capability of successfully decoding the data configured with the long-acting reference frame, so as to decode the encoded target data based on the long-acting reference frame in the encoded target data to obtain the target data, thereby enabling the terminal device 101 to utilize the long-acting reference frame as the reference frame in the decoding process, improving the decoding efficiency, and avoiding decoding errors caused by using the short-acting reference frame as the reference frame by the terminal device 101, and further improving the decoding accuracy.

The server 102 may be configured to send a probe request for the capability of the long-acting reference frame 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 the capability of successfully decoding the data configured with the long-acting reference frame, thereby determining whether to perform encoding using the encoding mode including the long-acting reference frame according to the capability of the terminal device 101. The server 102 may be further configured to encode the target data to obtain encoded target data including the long-acting reference frame if the probe information indicates that the terminal device 101 has the capability of successfully decoding the data configured with the long-acting reference frame, and send the encoded target data to the terminal device 101, so that the terminal device 101 may utilize the long-acting reference frame as the reference frame in the process of decoding the encoded target data, so as to improve decoding efficiency, and avoid decoding errors caused by using the short-acting reference frame as the reference frame by the terminal device 101, thereby improving decoding accuracy.

The Terminal device 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 wireless communication function, a computing device (e.g., a personal computer (personal computer, PC), a vehicle-mounted terminal, a smart voice interaction device, a wearable device or other smart apparatus, etc.).

The server 102 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or may be a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, basic cloud computing services such as big data and artificial intelligence platforms, 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, which is not limited herein.

It has been found that some terminal devices at present do not have the capability to successfully decode data configured with long-acting reference frames. If the server directly encodes by using the encoding mode comprising the long-acting reference frame, the encoding data comprising the long-acting reference frame is sent 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 may decode the encoded data in a short-acting reference frame manner, resulting in decoding failure. Based on this, the technical solution of the embodiment of the present application is provided, specifically, the server sends a detection request of the long-acting reference frame capability to the terminal device, and receives the detection information sent by the terminal device in response to the detection request, so that the server obtains whether the terminal device has the capability of successfully decoding the data configured with the long-acting reference frame, thereby determining whether to use the coding mode including the long-acting reference frame for coding according to the capability of the terminal device.

Specifically, the terminal device is configured with a hardware decoder, and decodes the encoded data through the hardware decoder, but the functions of the hardware decoders provided by different manufacturers are inconsistent, for example, a part of the hardware decoders do not provide support for the characteristics of the long-acting reference frames, that is, the hardware decoders cannot identify the long-acting reference frames, and only decode the encoded data in a short-acting reference frame mode. For a terminal device configured with such a hardware decoder, the terminal device may be considered to have no capability to successfully decode data configured with a long-acting reference frame.

Referring to fig. 2, fig. 2 is a flow chart of a data processing method according to an embodiment of the present application. The data processing method is applicable to the data processing system shown in fig. 1, and is executed by the terminal device and the server, and in particular, may 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 capacity to terminal equipment; accordingly, the terminal device receives a probe request for long-acting reference frame capabilities from the server.

The long-acting reference frame capability detection request can be used for detecting whether the terminal equipment has the capability of successfully decoding the data configured with the long-acting 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.

It should be noted that, the "probe request" is only a name used in the embodiments of the present application, and the name is not limited to the embodiments of the present application. Alternatively, the "probe request" may also be referred to as a "detection request", "test request", or "confirm request", etc., as 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 probe request may be responded, that is, a probe procedure of the long-acting reference frame capability is started, so as to determine whether the terminal device can successfully decode the data configured with the long-acting reference frame.

Specifically, the terminal device may obtain the test encoded data configured with the long-acting reference frame, and decode the test encoded 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 coded data may be sent by the server to the terminal device, for example, the test coded data may be carried in a probe request sent by the server. Alternatively, the test code data may be stored in the terminal device in advance, which is not limited in this application.

The long-acting reference frame refers to the coded frame of which the number of frame references in the tested coded data is larger than a preset number threshold 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 encoded data is 15 frames in total, the preset number of threshold values is 10 frames, the encoded frames referred to by the test encoded data of 12 frames in the decoding process can be determined as long-term reference frames. That is, in the decoding process, the long-acting reference frame may be decoded by frames greater than a preset number threshold as reference frames. The above-mentioned preset number threshold is 10 frames, which is only used for example and not limiting the application.

Alternatively, the coded frames referenced by the number of frames in the coded data under test that are less than or equal to the preset number threshold during decoding may be considered as short-term reference frames. For example, assuming that the test encoded data is 15 frames in total, the preset number of threshold values is 10 frames, the encoded frames referred to by the test encoded data of 8 frames in the decoding process can be determined as the short-term reference frames. That is, in the decoding process, the short-acting reference frame may be decoded by frames less than or equal to a preset number threshold as the reference frame.

In one implementation, the long-acting reference frame may be stored in the reference frame buffer for a duration greater than a preset storage duration. Optionally, the storage duration of the short-term 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 appreciated 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, i.e., 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 to avoid 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 greater than the preset storage duration. That is, the long-acting reference frame may remain in the reference frame buffer for a long time.

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

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

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

Wherein the decoding result may be used to indicate whether the terminal device successfully decoded the test encoded data. That is, the decoding result may indicate that the terminal device successfully decodes the test encoded data, or may indicate that the terminal device does not successfully decode the test encoded data. Specifically, the terminal device decodes the test coded data based on the long-acting reference frame, and can obtain the following decoding results:

decoding result one:

if the terminal equipment acquires the error code in the decoding process, a decoding result for indicating that the terminal equipment does not successfully decode the test coded data is generated. Wherein the error code may be returned to the terminal device through a decoding application program interface (Application Programming Interface, API). It should be noted that, if the terminal device acquires the error code during the decoding process, it may be indicated that the terminal device fails to decode the test encoded 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 acquires the correct code in the decoding process, it cannot be stated 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. Alternatively, the 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.

Decoding result two:

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

That is, after a preset period of time has elapsed from the start of decoding, if the terminal device does not acquire any feedback data, it may indicate that the terminal device fails to decode the test encoded 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 duration is 15ms, if the terminal device does not acquire any feedback data after 15ms from the start of decoding, it may also be understood that the terminal device is in a stuck state, and a decoding result for indicating that the terminal device has not successfully decoded the test encoded data is generated. Furthermore, if the terminal device acquires the feedback data after a preset time period from the start of decoding, it cannot be explained that the terminal device can successfully decode the test coded data configured with the long-acting reference frame, and further judgment on the decoding result is required.

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

Decoding result three:

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 coding data is generated; and if the test decoding data and the test data are not matched, generating a decoding result for indicating that the terminal equipment does not successfully decode the test coding data. The test coding data is obtained by coding the test data. That is, if the terminal device obtains 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 to successfully decode the test encoding data, thereby obtaining a decoding result.

In one implementation manner, the terminal device may calculate an information abstraction Algorithm (MD 5Message-Digest Algorithm, MD 5) value of the test decoding data, and 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 decoding data matches the test data, that is, generates a decoding result for indicating that the terminal device successfully decodes the test encoding data; if the md5 value is different from the reference value, the terminal device determines that the test decoding data and the test data are not matched, and generates a decoding result for indicating that the terminal device does not successfully decode the test encoding 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, which is not limited in this application. Since the md5 value corresponding to each data is unique, that is, if the md5 value of the test decoded data is the same as the md5 value of the test data (i.e., the reference value), it can be stated that the test decoded data matches the test data, that is, the terminal device successfully decodes the test encoded data.

Optionally, if a decoding result for indicating that the terminal device does not successfully decode the test encoded data is generated, which indicates that the terminal device cannot decode the encoded frame including the long-acting reference frame, the terminal device may empty cache data (e.g., test encoded data, feedback data, etc.) related to the detection flow of the long-acting reference frame capability, so as to later decode the encoded frame that does not include the long-acting reference frame.

In the embodiment corresponding to fig. 2, the terminal device successfully decodes the test encoded data configured with the long-acting reference frame and generates the decoding result (i.e., the third decoding result) for indicating that the terminal device successfully decodes the test encoded data is described as an example, which does not limit the application.

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

It should be noted that, in the case that the terminal device is configured with the hardware decoder, the terminal device may invoke the hardware decoder to execute the above-described probing 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 encoded data configured with the long-acting reference frame, and invoke the hardware decoder to decode the test encoded data based on the long-acting reference frame to obtain the decoding result.

Specifically, if the hardware decoder acquires the error code in the decoding process, a decoding result for indicating that the hardware decoder has not successfully decoded the test encoded data may be generated; if the hardware decoder does not acquire the feedback data after a preset time period from the start of decoding, a decoding result for indicating that the hardware decoder has not successfully decoded the test encoded data can be generated; under the condition that the test decoding data is obtained, 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; and if the test decoding data and the test data are not matched, generating a decoding result for indicating that the hardware decoder does not successfully decode the test coding data.

Optionally, if a decoding result is generated, which indicates that the hardware decoder fails to decode the test encoded data, indicating that the hardware decoder cannot decode the encoded frame including the long-acting reference frame, the terminal device may reset the hardware decoder, that is, empty the buffer data (e.g., test encoded data, feedback data, etc.) of the hardware decoder, so that the reset hardware decoder may decode the encoded frame that does not include the long-acting reference frame in a subsequent decoding process.

The sounding information may be used to indicate whether the terminal device has the capability to successfully decode the data configured with the long-acting reference frame. That is, the terminal device may transmit, to the server, probe information indicating that the terminal device has the capability of successfully decoding the data configured with the long-acting reference frame, based on the 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-acting reference frame, based on the decoding result of the unsuccessfully decoding the test encoded data.

S205, the server encodes the target data by adopting an encoding mode comprising the long-acting reference frame, and obtains encoded target data comprising the long-acting reference frame.

It should be noted that, when the probe information obtained 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 by using an encoding manner including the long-acting reference frame, so as to obtain encoded target data including the long-acting reference frame.

Optionally, in the case that the probe information obtained 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 by adopting an encoding mode including the short-acting reference frame, so as to obtain encoded target data including the short-acting reference frame.

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

After the server encodes the encoded target data including the long-acting reference frame, the encoded target data including the long-acting reference frame may be sent to the terminal device, so that the terminal device may decode the encoded target data based on the long-acting reference frame in the encoded target data in the decoding process, to obtain the target data, so as to improve decoding efficiency.

In one implementation, in the case where the probe 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; the server sends the coded target data comprising the short-term reference frame to the terminal equipment, so that the terminal equipment decodes the coded target data comprising the short-term reference frame based on the short-term reference frame to obtain the target data. Wherein, the short-term reference frame refers to the code frame of the frame reference of which the number is less than or equal to the preset number threshold value in the tested code data 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-acting reference frame, the server may encode the target data in an encoding manner including the short-acting reference frame, so as to obtain encoded target data including the short-acting reference frame, so that the terminal device may decode the encoded target data including the short-acting reference frame, and further obtain the target data.

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.

In addition, under the condition that the terminal equipment has the capability of successfully decoding the data configured with the long-acting reference frame, the encoded target data comprising the long-acting reference frame from the server can be received, and the encoded target data is decoded based on the long-acting reference frame in the encoded target data, so that the target data is obtained.

Optionally, in the case 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 this embodiment of the present invention, a server may enable a terminal device to obtain test encoded data configured with a long-acting reference frame in response to a probe request by sending the probe request with the capability of the long-acting reference frame to the terminal device, and decode the test encoded data based on the long-acting reference frame to obtain a decoding result, so that probe information indicating whether the terminal device has the capability of successfully decoding the data configured with the long-acting reference frame is sent to the server based on the decoding result, so that the server encodes the target data to obtain encoded target data including the long-acting reference frame when receiving the probe information indicating that the terminal device has the capability of successfully decoding the data configured with the long-acting reference frame, thereby being beneficial to improving decoding efficiency.
