Referring to fig. 1, an embodiment of the present invention provides a video backup method, including:
s1, when the mobile terminal deletes the video data packet, dividing the video data packet into at least a first data packet and a second data packet according to a preset rule, wherein the first data packet stores the start data of the video data packet;
s2, storing the first data packet in the local of the mobile terminal, backing up the second data packet to the cloud, and establishing the association between the first data packet and the second data packet in the cloud;
and S3, when the video of the first data packet is played, downloading the second data packet from the cloud to the local, and splicing the second data packet with the first data packet.
As described in step S1, the video data packet is a data set containing video data resources. When the first data packet is a video corresponding to the video data packet, a video data set containing the first video data is used, that is, when the video is played, the data in the first data packet must be used first. The second data packet is the video data packet which is formed after being combined with the first data packet. The second data packets can be divided into a plurality of second data packets according to specific conditions, and when the video is played, the plurality of second data packets are sequentially downloaded to form a complete video data packet with the first data packet, so that a user can watch the complete video. In general, only one second packet is set.
As described in steps S2 and S3, the cloud is a general network that can communicate with computers or obtain services provided by a remote host through a network. The first data packet is stored locally, the second data packet is uploaded to the cloud, the video data packet is split, and as a result, only the first data packet is left locally at the mobile terminal, the occupied storage space of the mobile terminal is small, and the storage space of the mobile terminal is effectively saved. And uploading the second data packet to the cloud end, so that the second data packet can be directly downloaded conveniently during downloading and use. When the video is watched, the first data packet is equivalent to the video data cached in advance, the second data packet is downloaded at the time of watching the video corresponding to the first data packet, the video can be watched smoothly when the network speed is poor, and the video watching experience of a user is improved. The association between the first data packet and the second data packet of the cloud terminal is established so as to conveniently inform the cloud terminal when the video in the first data packet is watched, and find the corresponding second data packet at the cloud terminal for downloading.
In this embodiment, the step of establishing the association between the first data packet and the second data packet in the cloud includes:
s21, recording a first local storage address of the first data packet and a second local storage address of the second data packet in the cloud;
and S22, associating the first storage address with the second storage address.
As described in the above steps S21 and S22, the first storage address of the first data packet and the second storage address of the second data packet are associated, so that when the video of the first data packet is played, the second storage address can be directly found from the first storage address, and the second data packet can be quickly found for downloading.
In this embodiment, the step S2 of saving the first data package in the local of the mobile terminal, backing up the second data package to the cloud, and establishing an association between the first data package and the second data package in the cloud includes:
s23, copying the second data packet through the cloud end, and performing resolution compression on the copied second data packet according to a preset compression command to form a first compressed data packet;
and S24, establishing association between the second data packet and the first compressed data packet respectively in the first data packet.
As described in the foregoing steps S23 and S24, the process of copying the second data packet and compressing the copied second data packet is performed at the cloud, so that the resource overhead of the mobile terminal is saved. The video content in the first compressed packet is the same as the video content in the second packet, but the resolution is lower, so the data size is smaller than that of the second packet, for example, the video corresponding to the second packet is high definition video, the data size is 1G, and the data size of the corresponding first compressed packet may only be 100M. The preset compression command is generally a specified compression ratio, for example, compression is performed according to a ratio of 10:1, and then the second data packet of 1G is compressed to form a first compressed data packet of 100M. The preset compression command may also be a compression ratio for automatically adjusting the resolution according to the resolution of the second data packet, for example, if the resolution of the video of the second data packet is originally low, a small ratio of compression may be performed, for example, if the second data packet is a standard definition video of 200M, the compression ratio may be 2:1, and a video with a lower resolution of 100M is obtained after compression. The second data packet and the first compressed data packet have different storage addresses, so that the first data packet is respectively associated with the second data packet and the first compressed data packet, and different data packets are selected for downloading according to the use condition.
In this embodiment, the step S3 of downloading the second data packet from the cloud to the local and splicing the second data packet with the first data packet when playing the video of the first data packet includes:
s31, judging whether the mobile terminal is in a free network or not;
s32, if the network is a free network, when the video of the first data packet is played, downloading the second data packet from the cloud to the local, and splicing the second data packet with the first data packet;
and S33, if the mobile terminal is in the charging network, downloading the first compressed data packet from the cloud to the local terminal and splicing the first compressed data packet with the first data packet when playing the video of the first data packet.
As described in the above steps S31, S32, and S33, the data amount of the video is generally large, and if the second packet is downloaded to view the video using the charged network, although the video with higher resolution can be viewed, it will be necessary to spend a higher cost, and if the first compressed packet is downloaded, it will cost a lower cost. The free network generally means that the mobile terminal is connected to a free WiFi network, and the data network such as 3G/4G provided by the mobile, unicom and other operators is a charging network.
In another embodiment, the step S3 of downloading the second data packet from the cloud to the local and splicing the second data packet with the first data packet when the video of the first data packet is played includes:
s34, acquiring the current data downloading speed of the mobile terminal;
s35, judging the time length of the second data packet after downloading according to the data downloading speed;
and S36, if the time length of the second data packet after downloading is longer than the time length of playing the video, downloading the first compressed data packet and splicing with the first data packet.
As described in the above steps S34, S35, and S36, since the resolution of the video corresponding to the second data packet is higher, the data size is larger, and if the data downloading speed is slower when the video is watched, after the video corresponding to the first data packet is watched and part of the data of the second data packet is downloaded instantly, a user may be stuck when watching the video, which affects the user experience. Therefore, the current data downloading speed is obtained first, the time length of finishing downloading the second data packet is calculated, and if the time length is longer than the time length of playing the video spliced by the first data packet and the second data packet, it indicates that the video cannot be watched smoothly and the pause phenomenon is inevitably generated. Therefore, it is more suitable to select the first compressed data packet with smaller data size, and the time length of the download from the cloud end may be shorter than the time length of the video after the splicing of the first data packet and the second data packet is played, so that the pause phenomenon does not occur in the playing. Even though the time length of the downloading from the cloud end is possibly longer than the time length of the video after the splicing of the first data packet and the first compressed data packet is played, the phenomenon of pause is slightly more slight than the phenomenon of pause when the second data packet is downloaded to watch the video.
In another embodiment, the step S2 of saving the first data package in the local of the mobile terminal, backing up the second data package to the cloud, and establishing an association between the first data package and the second data package in the cloud includes:
s25, the mobile terminal copies the second data packet and stores the second data packet locally, and the copied second data packet is subjected to resolution compression according to a preset compression command to form a second compressed data packet;
and S26, establishing the association between the second data packet and the second compressed data packet with the first data packet respectively.
As described in the foregoing steps S25 and S26, the process of copying the second data packet and compressing the copied second data packet is performed at the mobile terminal, and only the second data packet needs to be uploaded during backup, without uploading the second compressed data packet. Although the second compressed data packet is stored locally at the mobile terminal, it is compressed, so that the purpose of saving the storage space of the mobile terminal can still be achieved. The video content in the second compressed data packet is the same as the video content of the second data packet, but the resolution is lower, so the data size is smaller than that of the second data packet, for example, the video corresponding to the second data packet is high definition video, the data size is 1G, and the data size of the corresponding second compressed data packet may only be 100M. The preset compression command is generally a specified compression ratio, for example, compression is performed according to a ratio of 10:1, and then the second data packet of 1G is compressed to form a second compressed data packet of 100M. The preset compression command may also be a compression ratio for automatically adjusting the resolution according to the resolution of the second data packet, for example, if the resolution of the video of the second data packet is originally low, a small ratio of compression may be performed, for example, if the second data packet is a standard definition video of 200M, the compression ratio may be 2:1, and a video with a lower resolution of 100M is obtained after compression. The second data packet and the second compressed data packet have different storage addresses, so that the first data packet is respectively associated with the second data packet and the second compressed data packet, and different data packets are selected according to the use condition. And when the second compressed data packet is used, downloading is not needed, and network resources are saved.
In this embodiment, the step S3 of downloading the second data packet from the cloud to the local and splicing the second data packet with the first data packet when playing the video of the first data packet includes:
s301, judging whether the mobile terminal is in a free network or not;
s302, if the mobile terminal is in a free network, when the video of the first data packet is played, downloading the second data packet from the cloud to the local, and splicing the second data packet with the first data packet;
s303, if the mobile terminal is in the charging network, the second compressed data packet is called and spliced with the first data packet when the video of the first data packet is played.
As described in the above steps S301, S302 and S303, the data amount of the video is generally large, if the second packet is downloaded to view the video using the charged network, although the video with higher resolution can be viewed, it will be necessary to spend higher cost, and if the second compressed packet is downloaded, it is only necessary to directly call the video locally without spending any cost. The free network generally means that the mobile terminal is connected to a free WiFi network, and the data network such as 3G/4G provided by the mobile, unicom and other operators is a charging network.
In another embodiment, the step S3 of downloading the second data packet from the cloud to the local and splicing the second data packet with the first data packet when the video of the first data packet is played includes:
s304, acquiring the current data downloading speed of the mobile terminal;
s305, judging the time length of the second data packet after downloading according to the data downloading speed;
s306, if the time length of the second data packet after downloading is longer than the time length of playing the video, calling the second compressed data packet and splicing with the first data packet.
As described in the above steps S304, S305, and S306, since the resolution of the video corresponding to the second data packet is higher, the data size is larger, and if the data downloading speed is slower when the video is watched, if the video corresponding to the first data packet is watched and after part of the data of the second data packet is downloaded instantly, the user may be stuck when watching the video, which affects the user experience. Therefore, the current data downloading speed is obtained first, the time length of finishing downloading the second data packet is calculated, and if the time length is longer than the time length of playing the video spliced by the first data packet and the second data packet, it indicates that the video cannot be watched smoothly and the pause phenomenon is inevitably generated. And the local second compressed data packet is called to be spliced with the first data packet, downloading is not needed, and when the video is watched, only the video definition is influenced, but the video is watched smoothly, and the phenomenon of blocking cannot occur.
In this embodiment, the preset rule, that is, the rule for splitting the video data packet, includes: and acquiring the time length required by the video data packet when playing the video, and dividing the video data packet into a first data packet and a second data packet according to a preset playing time length division ratio. Namely, the video data packet is split according to the specified proportion of the time length of the video playing completion. For example, the split ratio is 1:9, and then a 100-minute movie is split to obtain a 10-minute first packet and a 90-minute second packet. During watching, the video resources used in the first 10 minutes are local to the mobile terminal, and the second data packet and the like are downloaded in the 10 minutes, so that the smoothness of watching the film is greatly improved.
In another embodiment, the preset rule, that is, the rule for splitting the video data packet, includes: and acquiring the capacity of the video data packet, and dividing the video data packet into a first data packet and a second data packet according to a preset capacity division ratio. Namely, the capacity of the video data packet is divided according to the designated proportion. For example, the split ratio is 1:9, then a 1000M movie is split to obtain 100M first packets and 900M second packets. When watching, the video resource used by the first 100M is local to the mobile terminal, and the second data packet and the like are downloaded during the video watching time of the first 100M, so that the fluency of watching the movie is greatly improved.
In another embodiment, the preset rule, that is, the rule for splitting the video data packet, includes: and acquiring the time length required by the video data packet when playing the video, and if the time length required by the video data packet when playing the video is greater than a preset time length threshold, dividing the video data packet into a first data packet and a second data packet according to the time length threshold, wherein the time length for playing the first data packet is equal to the time length threshold. The time length threshold is a designated time length, the mobile terminal measures the standard whether to split the video data packet, if the playing time length of the video data packet is greater than the time length threshold, the part of the time length corresponding to the time length threshold before the video data packet is played is split into a first data packet, and a second data packet is formed later. If the playing time length of the video data packet is less than or equal to the time length threshold, the split preset rule cannot be used. In a specific embodiment, the video playing time length corresponding to the video data packet is 100 minutes, and the time yield threshold is 10 minutes, so that the video data packet will use the data corresponding to the first 10 minutes of playing as the first data packet, and the data corresponding to the subsequent 90 minutes as the second data packet.
Referring to fig. 2, in this embodiment, after the step S3 of downloading the second data packet from the cloud to the local and splicing the second data packet with the first data packet when the video of the first data packet is played, the method includes:
and S4, automatically deleting the second data packet downloaded from the cloud after the video playing is finished.
As described in the above step S4, the video data packet is split into a first data packet and a second data packet, which indicate that the user has viewed the video, and then deleted, so as to save the storage space of the mobile terminal. Therefore, when the user watches the second data packet again, the second data packet downloaded from the cloud end is deleted after the user watches the second data packet, the use habit and the appeal of the user are met, the operation steps of the user are reduced, and the use experience of the user is improved. Certainly, when the second data packet downloaded from the cloud is deleted, a prompt selection button appears, and if the user does not want to delete the second data packet, the user can select a button such as "save" and the like to keep the second data packet in the mobile terminal.
In a specific embodiment, the mobile terminal of the user is a mobile phone, and a high-definition film with a data volume of 2000M is stored in the mobile phone, so that in daily life, the occupied storage space of the mobile phone is large, and the storage and use of the mobile phone by the user are influenced, so that the user wants to delete the high-definition film. When deleting, the mobile phone splits the data, and the data volume is divided into 1: and (3) splitting the ratio of 99 to obtain a first data packet of 20M and a second data packet of 1980M, uploading the second data packet to the cloud, copying the second data packet at the cloud, and performing 10:1 resolution compression on the copied second data packet to obtain a first compressed data packet of 198M. When the high-definition film is watched again, the current data downloading speed is judged firstly, if the duration of watching the high-definition film is shorter than the duration of downloading the second data packet, the first compressed data packet and the first data packet are selected to be downloaded and spliced, and the high-definition film is watched smoothly under the condition of sacrificing definition. After the mobile phone finishes watching, the mobile phone can automatically delete the downloaded first compressed data packet so as to save the storage space of the mobile phone.
According to the video backup and playing method, when the video data packet is deleted, the video data packet is split, a first section of data at the beginning of the video is formed into the first data packet, one or more second data packets are formed at the back and uploaded to the cloud, when a user watches the video, the content of the first data packet can be played at first, meanwhile, the second data packet can be downloaded from the cloud, and the video can be watched normally when the second data packet is downloaded. The method is the same as the method for downloading and watching the video in the prior art, but the first data packet is equivalent to the video data cached in advance, the second data packet is downloaded at the time of watching the video corresponding to the first data packet, the video can be watched smoothly when the network speed is poor, and the video watching experience of a user is improved.
Referring to fig. 3, the present embodiment further provides a video backup apparatus, including:
the splitting unit 10 is configured to, when the mobile terminal deletes a video data packet, split the video data packet into at least a first data packet and a second data packet according to a preset rule, where the first data packet stores start data of the video data packet;
the backup association unit 20 is configured to store the first data packet in the local of the mobile terminal, backup the second data packet to the cloud, and establish an association between the first data packet and the second data packet in the cloud;
and the playing and downloading unit 30 is configured to download the second data packet from the cloud to the local and splice the second data packet with the first data packet when playing the video of the first data packet.
As for the splitting unit 10, the video data packet is a data set containing video data resources. When the first data packet is a video corresponding to the video data packet, a video data set containing the first video data is used, that is, when the video is played, the data in the first data packet must be used first. The second data packet is the video data packet which is formed after being combined with the first data packet. The second data packets can be divided into a plurality of second data packets according to specific conditions, and when the video is played, the plurality of second data packets are sequentially downloaded to form a complete video data packet with the first data packet, so that a user can watch the complete video. In general, only one second packet is set.
As the backup association unit 20 and the broadcast downloading unit 30 are described above, the cloud is actually a general network, which can communicate computing tasks of multiple computers through a network or obtain services provided by a remote host through a network connection. The first data packet is stored locally, the second data packet is uploaded to the cloud, the video data packet is split, and as a result, only the first data packet is left locally at the mobile terminal, the occupied storage space of the mobile terminal is small, and the storage space of the mobile terminal is effectively saved. And uploading the second data packet to the cloud end, so that the second data packet can be directly downloaded conveniently during downloading and use. When the video is watched, the first data packet is equivalent to the video data cached in advance, the second data packet is downloaded at the time of watching the video corresponding to the first data packet, the video can be watched smoothly when the network speed is poor, and the video watching experience of a user is improved. The association between the first data packet and the second data packet of the cloud terminal is established so as to conveniently inform the cloud terminal when the video in the first data packet is watched, and find the corresponding second data packet at the cloud terminal for downloading.
Referring to fig. 4, in this embodiment, the backup association unit 20 includes:
the recording module 21 is configured to record a local first storage address of the first data packet and a cloud second storage address of the second data packet;
a first associating module 22, configured to associate the first storage address with the second storage address.
As mentioned above, the recording module 21 and the first associating module 22 associate the first storage address of the first data packet with the second storage address of the second data packet, and when playing the video of the first data packet, the second storage address can be directly found through the first storage address, so as to quickly find the second data packet for downloading.
Referring to fig. 5A, in this embodiment, the backup association unit 20 includes:
the first replication compression module 23 is configured to replicate the second data packet through the cloud, and perform resolution compression on the replicated second data packet according to a preset compression command to form a first compressed data packet;
a second associating module 24, configured to associate the second data packet and the first compressed data packet with the first data packet, respectively.
As the above first replication compression module 23 and the second association module 24, the process of replicating the second data packet and compressing the replicated second data packet is performed at the cloud, so that the resource overhead of the mobile terminal is saved. The video content in the first compressed packet is the same as the video content in the second packet, but the resolution is lower, so the data size is smaller than that of the second packet, for example, the video corresponding to the second packet is high definition video, the data size is 1G, and the data size of the corresponding first compressed packet may only be 100M. The preset compression command is generally a specified compression ratio, for example, compression is performed according to a ratio of 10:1, and then the second data packet of 1G is compressed to form a first compressed data packet of 100M. The preset compression command may also be a compression ratio for automatically adjusting the resolution according to the resolution of the second data packet, for example, if the resolution of the video of the second data packet is originally low, a small ratio of compression may be performed, for example, if the second data packet is a standard definition video of 200M, the compression ratio may be 2:1, and a video with a lower resolution of 100M is obtained after compression. The second data packet and the first compressed data packet have different storage addresses, so that the first data packet is respectively associated with the second data packet and the first compressed data packet, and different data packets are selected for downloading according to the use condition.
Referring to fig. 5B, in another embodiment, the backup association unit 20 includes:
the second replication compression module 25 is configured to replicate the second data packet and store the second data packet locally, and perform resolution compression on the replicated second data packet according to a preset compression command to form a second compressed data packet;
a third association module 26, configured to associate the second data packet and the second compressed data packet with the first data packet, respectively.
As mentioned above, the second replication compression module 25 and the third association module 26 replicate the second data packet and compress the replicated second data packet at the mobile terminal, and only the second data packet needs to be uploaded during backup, and the second compressed data packet does not need to be uploaded. Although the second compressed data packet is stored locally at the mobile terminal, it is compressed, so that the purpose of saving the storage space of the mobile terminal can still be achieved. The video content in the second compressed data packet is the same as the video content of the second data packet, but the resolution is lower, so the data size is smaller than that of the second data packet, for example, the video corresponding to the second data packet is high definition video, the data size is 1G, and the data size of the corresponding second compressed data packet may only be 100M. The preset compression command is generally a specified compression ratio, for example, compression is performed according to a ratio of 10:1, and then the second data packet of 1G is compressed to form a second compressed data packet of 100M. The preset compression command may also be a compression ratio for automatically adjusting the resolution according to the resolution of the second data packet, for example, if the resolution of the video of the second data packet is originally low, a small ratio of compression may be performed, for example, if the second data packet is a standard definition video of 200M, the compression ratio may be 2:1, and a video with a lower resolution of 100M is obtained after compression. The second data packet and the second compressed data packet have different storage addresses, so that the first data packet is respectively associated with the second data packet and the second compressed data packet, and different data packets are selected according to the use condition. And when the second compressed data packet is used, downloading is not needed, and network resources are saved.
Referring to fig. 6A, in this embodiment, the play downloading unit 30 includes:

As the first determining module 31, the data amount of the video is generally large, and if the second data packet is downloaded to watch the video using the charged network, although the video with higher resolution can be watched, it will probably cost higher, and if the first compressed data packet is downloaded, it will cost less. The free network generally means that the mobile terminal is connected to a free WiFi network, and the data network such as 3G/4G provided by the mobile, unicom and other operators is a charging network.
Referring to fig. 6B, in another embodiment, the play downloading unit 30 includes:
a first obtaining module 32, configured to obtain a current data downloading speed of the mobile terminal;

As mentioned above, the first obtaining module 32 and the second determining module 33, because the resolution of the video corresponding to the second data packet is higher, the data size is larger, if the data downloading speed is slower when the video is watched, then if the video corresponding to the first data packet is watched and after part of the data of the second data packet is downloaded instantly, the user may be stuck when watching the video, which affects the user experience. Therefore, the current data downloading speed is obtained first, the time length of finishing downloading the second data packet is calculated, and if the time length is longer than the time length of playing the video spliced by the first data packet and the second data packet, it indicates that the video cannot be watched smoothly and the pause phenomenon is inevitably generated. Therefore, it is more suitable to select the first compressed data packet with smaller data size, and the time length of the download from the cloud end may be shorter than the time length of the video after the splicing of the first data packet and the second data packet is played, so that the pause phenomenon does not occur in the playing. Even though the time length of the downloading from the cloud end is possibly longer than the time length of the video after the splicing of the first data packet and the first compressed data packet is played, the phenomenon of pause is slightly more slight than the phenomenon of pause when the second data packet is downloaded to watch the video.

As the third determining module 301, the data size of the video is generally large, if the second data packet is downloaded to watch the video through a charged network, although the video with higher resolution can be watched, the video will inevitably cost higher, and if the second compressed data packet is downloaded, the video can be directly called locally without spending any cost. The free network generally means that the mobile terminal is connected to a free WiFi network, and the data network such as 3G/4G provided by the mobile, unicom and other operators is a charging network.

As mentioned above, the second obtaining module 302 and the fourth determining module 303 have a higher resolution of the video corresponding to the second data packet, and the data size is larger, if the data downloading speed is slower when the video is watched, then if the video corresponding to the first data packet and part of the data of the second data packet are watched completely, the user may be stuck when watching the video, and the user experience is affected. Therefore, the current data downloading speed is obtained first, the time length of finishing downloading the second data packet is calculated, and if the time length is longer than the time length of playing the video spliced by the first data packet and the second data packet, it indicates that the video cannot be watched smoothly and the pause phenomenon is inevitably generated. And the local second compressed data packet is called to be spliced with the first data packet, downloading is not needed, and when the video is watched, only the video definition is influenced, but the video is watched smoothly, and the phenomenon of blocking cannot occur.

For example, the split ratio is 1:9, and then a 100-minute movie is split to obtain a 10-minute first packet and a 90-minute second packet. During watching, the video resources used in the first 10 minutes are local to the mobile terminal, and the second data packet and the like are downloaded in the 10 minutes, so that the smoothness of watching the film is greatly improved.

Namely, the capacity of the video data packet is divided according to the designated proportion. For example, the split ratio is 1:9, then a 1000M movie is split to obtain 100M first packets and 900M second packets. When watching, the video resource used by the first 100M is local to the mobile terminal, and the second data packet and the like are downloaded during the video watching time of the first 100M, so that the fluency of watching the movie is greatly improved.

The time length threshold is a designated time length, the mobile terminal measures the standard whether to split the video data packet, if the playing time length of the video data packet is greater than the time length threshold, the part of the time length corresponding to the time length threshold before the video data packet is played is split into a first data packet, and a second data packet is formed later. If the playing time length of the video data packet is less than or equal to the time length threshold, the split preset rule cannot be used. In a specific embodiment, the video playing time length corresponding to the video data packet is 100 minutes, and the time yield threshold is 10 minutes, so that the video data packet will use the data corresponding to the first 10 minutes of playing as the first data packet, and the data corresponding to the subsequent 90 minutes as the second data packet.

The audio circuit 1160 may transmit the electrical signal converted from the received audio data to the speaker 1161, and convert the electrical signal into a sound signal for output by the speaker 1161; on the other hand, the microphone 1162 converts the collected sound signals into electrical signals, which are received by the audio circuit 1160 and converted into audio data, which are then processed by the audio data output processor 1180, and then transmitted to, for example, another cellular phone via the RF circuit 1110, or output to the memory 1120 for further processing.
WiFi belongs to short-distance wireless transmission technology, and the cell phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 1170, and provides wireless broadband internet access for the user.
