Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating an architecture of an online multimedia file downloading system according to an embodiment of the present invention. As shown in fig. 1, the online multimedia file download system 100 includes several clients 11 and a content server 12.
The communication method between the clients 11 supports the P2P method, and therefore, the clients 11 operate in the peer-to-peer network.
The client 11 has a display screen, which may be a touch screen or a non-touch screen, and may be a TFT screen (TFT Thin Film Transistor), a TFD screen (TFD Thin Film Diode), a UFB screen (Ultra Thin Film Bright, UFB), an STN screen (Super-Twisted Nematic, STN), an OLED screen (Organic Light-Emitting Diode), an AMOLED screen (Active Matrix/Organic Light-Emitting Diode, AMOLED Active Matrix Organic Light-Emitting Diode panel), and so on.
The client 11 supports the installation of various applications, such as one or more desktop applications from among the following: download applications, drawing applications, presentation applications, word processing applications, spreadsheet applications, gaming applications, telephone applications, video conferencing applications, email applications, instant messaging applications, training support applications, photo applications, digital camera applications, digital video recorder applications, web browsing applications, digital music player applications, digital video player applications, and the like. In some embodiments, some applications include contacts, such as: a telephone application, an email application, an instant messaging application, and the like.
Each client 11 is communicatively coupled to a content server 12. The content server 12 may be a physical server or a logical server virtualized from multiple physical servers. The server may also be a server cluster formed by a plurality of servers capable of communicating with each other, and each functional module may be respectively distributed on each server in the server cluster.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for downloading an online multimedia file according to an embodiment of the present invention. As shown in fig. 2, the online multimedia file downloading method S200 includes:
s21, acquiring a current data packet corresponding to the current playing progress of the online multimedia file;
in the present embodiment, the multimedia file includes a video file, an audio file, or a text file, etc. When the multimedia file is a video file, the current playing progress is the current playing time point of the video, for example, a video with a total duration of 60 minutes, and the current playing time point is the 32 th minute, so the 32 th minute is the current playing progress of the video file. When the multimedia file is an audio file, the understanding of the current playing progress is as described above. When the multimedia file is a text file, the current playing progress is the position of the current content exposed on the current display screen of the target client at the text, for example, the total number of pages of the text file is 100, and if the user browses the 35 th page of the text file, the 35 th page is the current playing progress of the text file.
In the peer-to-peer network, the online multimedia file is divided into a plurality of data packets, each data packet can be stored by different clients, when the target client plays the online multimedia file, the target client sends a file downloading request to the content server, and the content server sends the network address of the target client to other clients, so that the other clients establish P2P communication with the target client according to the network address of the target client.
When the target client plays the online multimedia file, the current playing progress of the online multimedia file and a current data packet corresponding to the current playing progress are determined.
S22, determining a target cache data packet which is continuously arranged behind the current data packet according to the playing time sequence;
in this embodiment, the target client normally plays the online multimedia file according to the playing time sequence. As described above, an online multimedia file is divided into a plurality of data packets according to the playing time sequence, and each data packet is configured with a number according to the playing time sequence. Each packet may be uploaded to the target client by a different neighbor node. For example, an online video is divided into 5 packets, i.e., packets M1, M2, M3, M4, and M5, wherein the packets M1, M2, M3, M4, and M5 are arranged in the playing time sequence. In some embodiments, the data packets M1, M2, M3, M4, and M5 may be uploaded to the target client by different neighbor nodes. In other embodiments, the data packet M1 and the data packet M2 may be uploaded by the same neighbor node, and the data packets M3, M4, and M5 may be uploaded by the same neighbor node.
In this embodiment, the target buffer packet is consecutive to and arranged after the current packet in the playing time order. For example, when the target client plays an online video, the current packet corresponding to the current playing progress is the packet M2, where the packet M3 and the packet M2 are consecutively arranged after the packet M2, and therefore the packet M3 is the target cache packet.
S23, detecting the downloading speed of the node for downloading the target cache data packet;
in this embodiment, the communication distance between the node for downloading the target cache data packet and the target client is relatively short, and may also be relatively long, that is, the node for downloading the target cache data packet may be a neighboring node, or may also be a far neighboring node.
And S24, adjusting the downloading mode of the target cache data packet according to the playing speed of the target client and the downloading speed of the node, wherein the downloading mode comprises a first downloading mode in which the target client directly downloads the data packet from the content server and a second downloading mode in which the target client downloads the data packet from the node.
The content server stores online multimedia files. Generally, since the priority download mode of most clients is the second download mode for downloading the data packet from the node, and fewer clients access the content server, the download speed corresponding to the first download mode is greater than the download speed corresponding to the second download mode.
In this embodiment, when the play speed of the target client is greater than the download speed of the node, the target client selects the first download mode to download the target cache data packet from the content server. And when the playing speed of the target client is lower than the downloading speed of the node, the target client selects a second downloading mode to download the target cache data packet from the node.
In summary, since it can flexibly provide a plurality of download modes to download the online multimedia file, it can ensure that the user can smoothly view the online multimedia file.
Generally, some users habitually play online multimedia files in a fast-forward manner, resulting in easy occurrence of a pause phenomenon. In some embodiments, it can adjust the downloading mode of the target cache data packet according to the user usage habit, so as to smoothly play the multimedia file. Referring to fig. 3, S24 includes:
s241, obtaining a play history of the target client, wherein the play history comprises the fast forward times of the target client playing the historical multimedia files according to the fast forward speed and the historical number of the played historical multimedia files;
for example, in the history of playing, when the multimedia file is played for the first time, the user fast-forwards the multimedia file at 2 times of the normal playing speed, that is, the fast-forwarding speed is 2 times of the normal playing speed, and for the multimedia file with the playing duration of 60 minutes, the user fast-forwards for 6 times. When another multimedia file is played for the second time, the user fast-forwards 8 times for the multimedia file with the playing time of 120 minutes. When another multimedia file is played for the third time, the user fast forwards for 2 times for the multimedia file with the playing time of 120 minutes. Thus, the play history multimedia file has a fast forward count of 6+8+2 to 16, and the play history multimedia file has a history number of 3.
S242, calculating the ratio of the fast forwarding times to the historical number;
and S243, adjusting the downloading mode of the target cache data packet according to the playing speed of the target client, the downloading speed of the node and the ratio of the fast forward times to the total times.
In this embodiment, when adjusting the download mode of the target cache data packet, the target client may determine whether the play speed of the target client is greater than the download speed of the node, and if the play speed of the target client is greater than the download speed of the node, adjust the download mode of the target cache data packet and the cache data packets with the preset length continuously arranged behind the target cache data packet according to a ratio between the number of fast forwarding times and the historical number. For example, the target client determines whether the ratio between the number of fast forwarding times and the historical number is greater than a preset ratio threshold; if the ratio between the number of fast forwarding times and the historical number is larger than a preset ratio threshold, judging whether the downloading speed of a node corresponding to a preset-length cache data packet continuously arranged behind the target cache data packet is larger than the fast forwarding speed, if so, selecting a first downloading mode to download the target cache data packet and selecting a second downloading mode to download a preset-length cache data packet continuously arranged behind the target cache data packet, and if not, selecting the first downloading mode to download the target cache data packet and the preset-length cache data packet continuously arranged behind the target cache data packet.
And if the ratio of the fast forward times to the historical number is smaller than a preset ratio threshold, selecting a first download mode to download the target cache data packet and selecting a second download mode to download the cache data packets with preset lengths which are continuously arranged behind the target cache data packet.
And if the playing speed of the target client is lower than the downloading speed of the node, selecting a first downloading mode to download the target cache data packet.
Therefore, in this way, it can ensure that the user smoothly plays the online multimedia file.
In some embodiments, the online multimedia file is divided into a number of packets, each packet having a corresponding number. When the target client selects the first downloading mode to download the target cache data packet, firstly, the target client sends the number of the target cache data packet to the content server, and then the content server returns the target cache data packet to the target client according to the number of the target cache data packet, so that the target client receives the target cache data packet returned by the content server.
It should be noted that, in the foregoing embodiments, a certain order does not necessarily exist between the foregoing steps, and it can be understood by those skilled in the art from the description of the embodiments of the present invention that, in different embodiments, the foregoing steps may have different execution orders, that is, may be executed in parallel, may also be executed in an exchange manner, and the like.
