Detailed Description
Embodiments of the present application are described below with reference to the accompanying drawings.
In the related art, in order to reduce the transcoding pressure of the user-side terminal device, a server for transmitting data to the terminal device first detects a network environment in which the terminal device is located, where the network environment can embody the amount of data that the terminal device can receive in between units. It can be understood that, for video data of the same duration, the higher the resolution of the data has the larger data amount, so that the server can send the video data with the higher resolution to the terminal device with the better network environment and send the video data with the lower resolution to the terminal device with the poorer network environment after transcoding the video data into video data with multiple resolutions, thereby reducing the network resource loss of the terminal device to a certain extent.
However, since the conditions of the terminal devices are different, and the resolutions of the video data that can be played by the terminal devices are also different, when the conditions of the terminal devices are poor, if the terminal devices are in a better network environment, the server still sends data with higher resolution to the terminal devices in the related art, and therefore the terminal devices may still not play the data, and need to perform further transcoding, which increases the transcoding processing pressure for the terminal devices.
In order to solve the technical problem, the application provides a data transmission method, which selects a target version suitable for being played by a terminal device from target data of multiple resolution versions through video data resolution information capable of being played by the terminal device, and then obtains the target data of the target version from a data transmission address of the target version, so that the terminal device can obtain video data capable of being directly played without further transcoding, transcoding processing pressure is reduced, and network resource loss is reduced.
It is understood that the method may be applied to a processing device, which is a processing device with a data transmission function, for example, a terminal device or a server with a data transmission function. The method can be independently executed through the terminal equipment or the server, can also be applied to a network scene of communication between the terminal equipment and the server, and is executed through the cooperation of the terminal equipment and the server. The terminal device may be a computer, a Personal Digital Assistant (PDA), a tablet computer, or the like. The server may be understood as an application server or a Web server, and in actual deployment, the server may be an independent server or a cluster server. Meanwhile, in a hardware environment, the technology has been implemented in the following environments: an ARM architecture processor, an X86 architecture processor; in a software environment, the technology has been implemented in the following environments: android platform, Windows xp and operating systems or Linux operating systems.
In order to facilitate understanding of the technical solution of the present application, the data transmission method provided in the embodiment of the present application is introduced below with reference to an actual application scenario.
Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a data transmission method provided in an embodiment of the present application. In this application scenario, the processing device is terminal device 101. When the viewing user wants to view a video, the video may be opened in the terminal device through a certain operation, for example, clicking a video playing interface, etc., by which a viewing request may be generated in the terminal device 101. Since the opening operation is performed on a certain video data, the terminal device 101 may determine, according to the viewing request, a target data identifier corresponding to the video data; meanwhile, since the video data is played in the terminal device 101, the terminal device 101 may also obtain, according to the viewing request, playback resolution information that can be played when the terminal device plays the video data.
It can be understood that, in order to improve the viewing experience and the selection flexibility of the user, for the same video data, multiple resolution versions are often provided for the user to select, for example, when the user watches a movie, the user may select multiple resolutions such as 1080P, 720P, 360P to play, and the selection of different resolutions may cause the terminal device to obtain the video data of the movie from different data transmission addresses, so that, multiple data transmission addresses correspondingly store the resolution versions of the same movie video, that is, the multiple versions have the same target data identifier, and therefore, the target data identifier can identify the multiple data transmission addresses of the target data.
Based on this, the terminal device 101 may determine, according to the target data identifier, a plurality of data transmission addresses of the target data identifier, where different resolution versions of the target data are correspondingly stored, from the video data server storing the video data related information. In this practical application scenario, the terminal device 101 can determine the data transmission addresses 1, 2, and 3, and correspondingly store the resolution versions 1, 2, and 3 of the target data.
It can be understood that the playing resolution information can embody the playing capability of the terminal device 101 in the playing area, that is, the resolution of the played video data cannot exceed the playing resolution, and when the resolution exceeds the playing resolution, the terminal device 101 needs to transcode further to be able to play the video data; when the resolution does not exceed the threshold, the terminal device 101 may play without processing, but too low resolution may also affect the viewing experience of the user. Therefore, in order to reduce the transcoding processing pressure of the terminal device 101 and at the same time to ensure the viewing experience of the user to some extent, in this practical application scenario, the terminal device 101 may determine a target version corresponding to the playback resolution information from the acquired multiple resolution versions.
In this actual application scenario, according to the playing resolution information, the terminal device 101 may determine, from the multiple resolution versions, the resolution version 2 that meets the above condition as the target version. After determining the required resolution version, in order to be able to play the video data to the user, the terminal device 101 may determine, according to the target version, a data transmission address for storing the target version from the plurality of data transmission addresses, and obtain target data transmission data of the target version through the data transmission address. In this practical application scenario, the target data of resolution version 2 is saved as the data transmission address 2, and therefore, the terminal device 101 can obtain the target data of resolution version 2 through the data transmission address 2 and provide the target data for the user to view.
Therefore, as the terminal device 101 determines the video data to be transmitted according to the resolution information that can be played by itself, the video data obtained by transmission can be directly played by the terminal device 101 without further transcoding, and the transcoding pressure of the terminal device 101 is reduced to a certain extent; meanwhile, the terminal device 101 only needs to transmit the video data with the proper resolution, so that the occupied network resources are less, and the waste of the network resources is reduced.
Next, a data transmission method provided by an embodiment of the present application will be described with reference to the drawings.
Referring to fig. 2, fig. 2 shows a flow chart of a data transmission method, which includes:
s201: and determining the target data identification and the playing resolution information according to the viewing request.
In daily life, users may generate various video data acquisition demands, such as watching movies, animations, and watching a video broadcast of a star or a network red person. When a user generates a viewing demand for a certain target data, a viewing request for the target data may be triggered by an operation in the processing device. For example, when the target data is a movie video, the user may click on a picture cover corresponding to the movie video through the processing device to trigger a viewing request.
It can be understood that, since the viewing request is triggered for the target data, after the viewing request in the processing device is triggered, the processing device may determine a target data identifier according to the viewing request, where the target data identifier can be used to embody the data selected by the user. Meanwhile, when the user triggers the viewing request, since the target data needs to be played to the user, the processing device also generates related information for playing the target data, including the playing resolution information and the like.
The playback resolution information refers to the highest resolution of the target data that can be played back by the processing device when the target data is played back. The playback resolution information depends on the device resolution that the processing device itself has, and the playback area in the processing device for playing back the target data. The device resolution refers to a resolution that can be played by the processing device on a hardware level, for example, a screen resolution of the processing device, a video resolution that can be analyzed by the processing device, and the like, where a resolution of target data that can be played by the processing device with a better hardware condition may be higher. The influence of the playback area on the playback resolution is mainly achieved from the size of the playback area, and in the same processing device, when the playback area for playing back the target data is larger, the resolution of the target data that can be played back may be higher.
As shown in fig. 3, fig. 3 shows three different playing areas in the same processing device, in fig. 3, the processing device is a mobile phone, and the target data is a certain live data in a live platform. Fig. 3 shows a small-screen playing area, a floating-window playing area, and a full-screen playing area, respectively. The small-screen playing area can facilitate a user to watch live broadcast video through the small-screen playing area while watching the live broadcast video, and can receive comment data sent by other users watching the same live broadcast through the comment area; the floating window playing area is floated on the uppermost layer of the current interface, so that a user can browse information and play live video through the floating window while browsing information of a plurality of live rooms. It can be understood that, in order to enable the user to browse more information of the live broadcast room, the floating window playing area is generally smaller than the small-screen playing area; the full-screen playing area means that a user watches the live video through the whole mobile phone screen, and the playing area of the user is the largest.
Therefore, the playback resolution information determined by the processing device may be different for processing devices with different hardware configurations and different playback areas of the same processing device. In order to enable the target data to be obtained without transcoding the target data, the processing device may obtain the playback resolution information according to the viewing request, and obtain the subsequent target data according to the playback resolution information.
S202: a plurality of data transfer addresses are determined at which the target data identifies the identified target data.
It will be appreciated that the same video data may be stored in the server in multiple resolution versions in order to meet the needs of different users when viewing the data. In order to be able to obtain the target data of the respective resolution versions, different resolution versions of the target data may be correspondingly stored in the server by a plurality of data transfer addresses. When the target data of a certain resolution version needs to be played, the processing device only needs to determine the data transmission address for storing the target data of the resolution version, and the target data can be acquired through the data transmission address. Since the target data of the resolution versions are the same target data, the data transmission addresses for storing the resolution versions correspond to the same target data identification.
In order to determine target data which can be played without transcoding again, the processing device may determine, through the obtained target data identifier, a plurality of data transmission addresses corresponding to the target data identifier, and determine a subsequent resolution version according to different resolution versions stored in the plurality of data transmission addresses.
S203: and determining a target version corresponding to the playing resolution information from the plurality of resolution versions.
After obtaining the playback resolution information and the multiple resolution versions stored by the multiple data transmission addresses, the processing device may determine the target data of the required target version according to the information.
As mentioned above, the playing resolution information can embody the target data with the highest resolution that the processing device can play without further transcoding. Therefore, in order to reduce the transcoding processing pressure of the processing device and ensure the resolution quality of the target data viewed by the user as much as possible, the processing device may determine the target version corresponding to the playback resolution information from the multiple resolution versions.
It is to be understood that, when there is a version of the plurality of resolution versions that is the same as the resolution of the playback resolution information, the processing device may directly determine the resolution version as the target version; when the resolution versions do not have the same version as the playback resolution information, the playback resolution information is the highest resolution that can be played by the processing device, and therefore, in order to enable the processing device to avoid transcoding processing and to increase the resolution of data viewed by the user as much as possible, the processing device may set, as a target version, a resolution version that is closest to but not exceeding the playback resolution information from among the resolution versions.
S204: and obtaining the target data of the target version by storing the data transmission address of the target version.
After the target version is determined, the processing device may determine, from the plurality of data transmission addresses determined according to the target data identifier, a data transmission address in which the target data of the target version is stored, and acquire the target data of the target version through the data transmission address. After the acquisition, the processing device may play the target data of the target version through the play area.
According to the technical scheme, the processing device can receive the watching request when the user wants to watch the video data, and obtain the target data identification and the playing resolution information which can be played in the playing area according to the watching request, wherein the target data identification can identify a plurality of data transmission addresses of the target data, and each data transmission address stores target data of a resolution version. The processing equipment can select a target version corresponding to the playing resolution information from the multiple resolution versions according to the playing resolution information, and finally obtains target data of the target version by storing the data receiving address of the target version, so that the processing equipment is not required to directly transmit video data with the highest resolution, and only the data with the resolution which can be played by a terminal for playing the video data is required to be transmitted, so that the terminal equipment is not required to transcode, the network resource loss is reduced to a certain extent, and the transcoding processing pressure of the processing equipment is reduced.
It is understood that, in some processing devices, when a user makes a request to view certain video data, at the time of performing a corresponding operation on the processing device, there may not be a determined playback area in the processing device, which is an area for playing back target data in the processing device. For example, when a user browses in an interface having multiple anchor live broadcast rooms, a requirement may be generated to want to watch a certain anchor live broadcast, and at this time, before the user clicks the anchor live broadcast room, an area for playing the live broadcast data does not exist in the processing device, so that the processing device cannot directly obtain the playing resolution information by clicking a triggered viewing request by the user.
In order to enable the processing device to obtain the playing resolution information in the above case, in one possible implementation, the processing device may determine the target data identifier according to the viewing request, then determine the playing area corresponding to the target data identifier, and determine the playing resolution information of the playing area. For example, in the above situation, the processing device may first obtain, through a main broadcast live broadcast room clicked by a user, a live broadcast data identifier of the main broadcast as a target data identifier, and then when the processing device jumps to an interface for playing the main broadcast live broadcast data according to a viewing request triggered by a user operation, the processing device may find a playing area for playing the live broadcast data according to the live broadcast data identifier, and finally determine playing resolution information according to the playing area.
It can be understood that the processing device is mainly a terminal device for playing target data, and how to complete the data transmission method provided in the embodiment of the present application by using the terminal device is shown. Besides, the embodiment of the present application can also be implemented by a processing device mainly including a server. As shown in fig. 4, fig. 4 shows a flow chart of a data transmission method, which includes:
s401: and receiving a data request sent by the terminal equipment.
When a user generates a demand for playing certain video data, in order to play the video data, a viewing request for the video data is triggered by clicking or the like. The terminal device for playing the video data may determine the target data identifier and the playing resolution information based on the viewing request by using the method in the foregoing technical solution. In order to obtain the target data for playing, the terminal device may generate a data request according to the target data identifier and the playing resolution information, and send the data request to the processing device for transmitting data.
The processing device may receive a data request sent by the terminal device, where the data request includes a target data identifier and playback resolution information. The target data identification is used for identifying video data which needs to be watched by a user, and the playing resolution information can embody the highest resolution of the data which can be played by the terminal device.
S402: a plurality of data transfer addresses are determined at which the target data identifies the identified target data.
The target data identified by the target data identification has a plurality of data transmission addresses, the target data has a plurality of resolution versions, and different resolution versions of the target data are correspondingly stored in the plurality of data transmission addresses. The processing device can determine a plurality of data transmission addresses of the target data identified by the target data identification according to the target data identification in the data request.
S403: and determining a target version corresponding to the playing resolution information from the plurality of resolution versions.
After the processing device obtains the multiple resolution versions and the playing resolution information, in order to enable the transmitted target data to be free from further transcoding processing by the terminal device, the processing device may determine a target version corresponding to the playing resolution information from the multiple resolution versions.
S404: and sending the target data of the target version to the terminal equipment by storing the data transmission address of the target version.
After determining the target version, the processing device may determine, according to the target version, a data transmission address for storing target data of the target version from among the plurality of data transmission addresses, and then send the target data of the target version to the terminal device through the data transmission address, so that the terminal device may play the target data to the user through the playing area without transcoding after receiving the target data.
It can be understood that, in order to enable the terminal device to directly obtain target data of a suitable resolution version, the processing device may transcode the uploaded data into multiple resolution versions before the user views the target data, so as to meet the obtaining requirements of different users through different terminal devices. In a possible implementation manner, before receiving a data request sent by a terminal device, a processing device may receive upload data, transcode the upload data into target data of multiple resolution versions according to upload resolution information corresponding to the data, and then store the target data of the multiple resolution versions through multiple data transmission addresses. The upload resolution information refers to resolution information of the upload data.
For example, when the technical solution of the embodiment of the present application is applied to the live broadcast field, the upload data may be live broadcast data uploaded by a host. As shown in fig. 5, three modules, namely a push streaming module, a transcoding module and a pull streaming module, may be included in the processing device. The stream pushing module is used for receiving live broadcast data uploaded by the anchor broadcast. As shown in fig. 6, fig. 6 is a flowchart of a host uploading live data, where the host may select a certain resolution as an uploading resolution to upload, for example, 360P, 540P, 720P, 1080P and the like, according to a network condition where the host is located or other factors, and after determining the uploading resolution, the host may obtain a streaming address for uploading data in a manner of live broadcasting software and the like, and upload the live data through the streaming address.
The processing device can receive live broadcast data through the stream pushing module and then send the live broadcast data to the transcoding module for transcoding. It is understood that, in order to ensure the quality of the transcoded live data, the processing device may transcode the live data into lower-resolution live data, for example, when the uploaded live data is 720P, the processing device may transcode the live data by means of downsampling, and the like, and generate 540P and 360P live data. Down-sampling refers to a process of reducing the resolution of video data. As shown in fig. 7, fig. 7 is a flowchart of transcoding performed by a processing device at a transcoding module. The processing device can analyze the live broadcast data acquired by the stream pushing module to determine the uploaded resolution information, then perform down-sampling processing, and finally generate a plurality of data transmission addresses for storing the live broadcast data of each resolution version. The multiple resolution versions comprise a resolution version uploaded on the main broadcasting and each resolution version obtained by down sampling.
Finally, in the stream pulling module, as shown in fig. 8, fig. 8 is a flowchart of a process device for performing transmission in the stream pulling module, and the process device may obtain all corresponding data transmission addresses according to a target data identifier in the data request, determine live data of a target version according to the playback resolution information, and then determine a data transmission address in which the live data of the target version is stored to perform data transmission.
Next, a data transmission method provided in the embodiment of the present application will be described in conjunction with an actual application scenario. In the actual application scene, the target data identifier is a target live broadcast data identifier and is used for identifying live broadcast data of a main broadcast selected by a user, the data transmission address is a live broadcast data streaming address, the playing area is used for playing target live broadcast data of a target version, and the processing device is a 1080P smart phone held by the user.
The user can trigger the watching request by clicking the anchor icon in the mobile phone and enter the live broadcasting room corresponding to the anchor. The mobile phone can determine a target live broadcast data identifier according to the watching request, and determine playing resolution information of a current live broadcast data area through the target live broadcast data identifier, wherein in the actual application scene, the playing area is a small-screen playing area. As shown in the following table, the following table shows the playing resolution information of different mobile phones in different playing areas.
| Cell phone type | Full screen playing area | Small screen playing area | Floating window play area |
| 1080P mobile phone | 1920x1080 | 1080x608 | 864x486 |
| 720P mobile phone | 1280x720 | 720x405 | 576x324 |
