In the present invention, the multimedia file includes: picture files, and/or audio-video files, and/or streaming media files, etc.
The invention is described in further detail below with reference to the figures and the embodiments.
Fig. 2 is a schematic flow chart of a method for implementing multimedia on demand based on LTE according to the present invention, and as shown in fig. 2, the method includes the following implementation steps:
step 201: the mobile terminal logs in a multimedia on-demand server;
the method specifically comprises the following steps: the mobile terminal needs to log in before obtaining the service of the multimedia on-demand server, the mobile terminal can send information such as a self account number, a password and the like to the multimedia on-demand server, and the multimedia on-demand server returns a message of successful login after confirming the information.
Here, the user has registered online before logging in to the multimedia on demand server, such as: the mobile terminal is registered in the multimedia on demand server through the personal computer, and after the registration, the multimedia on demand server stores the information of the mobile terminal for identity authentication when the mobile terminal logs in.
Step 202: the mobile terminal sends a request for inquiring the scheduling to the multimedia on-demand server, and the multimedia on-demand server returns a scheduling list;
the method specifically comprises the following steps: the mobile terminal sends the request for inquiring the scheduling to the multimedia on demand server through the LTE network, and the multimedia on demand server returns the set scheduling list to the mobile terminal after receiving the request.
In the invention, in order to ensure the expandability of the communication protocol, the communication between the mobile terminal and the multimedia on demand server is completed by adopting an extensible markup language (XML), for example: the statement to get the schedule list can be expressed as: < Request > GetPlayList </Request >,
wherein the Request field is used for specifying a current communication purpose; the GetPlayList represents an acquisition scheduling list; if GetPlaomadieng is substituted for GetPlayList in the sentence, the meaning of the sentence can be expressed as obtaining text information such as news reports.
Here, the schedule list is preset and stored by the multimedia on demand server before the mobile terminal communicates with the multimedia on demand server, and the schedule list may include: types of multimedia files, such as: news, advertisements, emergency notifications, etc.; storing a folder name of a multimedia file; a link address of the multimedia file; the specific scheduling of playing multimedia files; wherein, a plurality of multimedia files with the same type are stored in the same folder.
The arrangement of the scheduling also adopts XML, and the specific statements are as follows:
<PlayList>
<PlayListId>001<></PlayListId>
<TimeBegin>1:00</TimeBegin>
<TimeEnd>2:00</TimeEnd>
<Mode>1</Mode>
…
<ListType>1</ListType>
…
<Area>a</Area>
…
wherein the PlayList is used to describe a play sequence condition within a one-hour time period; the playlist id is used to identify the currently playing record, i.e. to identify the currently playing multimedia file; the TimeBegin and the TimeEnd are used for describing the starting time and the ending time of the playing of the multimedia file; the Mode is used for describing the cutting condition when the display screen is played; the ListType represents a play type of the multimedia file, such as: 1 represents that the video is played in non-real time, and 2 represents that the video is played in real time; the Area represents the display Area of the multimedia file in the divided Area of the display screen, and other fields and the meanings thereof are not listed one by one here.
Step 203: the mobile terminal selects the required multimedia file from the received scheduling list and stores the related information of the selected multimedia file;
the method specifically comprises the following steps: after receiving the scheduling list sent by the multimedia on demand server, the mobile terminal selects an interested multimedia file, for example: the required multimedia file can be selected according to the type of the multimedia file, and after the mobile terminal executes the selection operation, the related information of the selected multimedia file is stored, for example: link addresses for storing multimedia files, a specific schedule for playing the multimedia files, and the like, for performing subsequent downloading and playing operations.
Step 204: the mobile terminal downloads the multimedia files from the multimedia on-demand server and plays the multimedia files according to the scheduling corresponding to the multimedia files;
here, since the multimedia files include picture files, audio/video files, and streaming media files, the acquisition manner and the storage manner are different for different multimedia files. The picture file and the audio and video file are played after being downloaded to the mobile terminal, and the streaming media file is downloaded and played in real time, specifically as follows:
for picture files and audio and video files, the mobile terminal downloads the required files from the multimedia on-demand server by using a file transfer protocol (Ftp)/hypertext transfer protocol (Http) according to the link addresses of the stored multimedia files, when downloading, the whole folder for storing the picture files and/or the audio and video files is downloaded to the mobile terminal, and after downloading is finished, the multimedia files are played according to the stored schedule corresponding to the multimedia files, for example: playing areas, playing time periods and the like of the multimedia files on the display screen of the mobile terminal;
for a streaming media file, the downloading operation is usually controlled by a streaming media player arranged in the mobile terminal, and the streaming media player downloads the streaming media file from a multimedia on-demand server in real time according to a link address of the streaming media file stored in the mobile terminal, and performs decoding playing while downloading, wherein a real-time transport protocol (RTP) commonly used in the prior art is adopted during downloading, and the streaming media file is played according to a set schedule.
Here, because the LTE network is complex, a problem that the connection between the mobile terminal and the multimedia on-demand server may fail may occur, at this time, the streaming media player may frequently attempt to reconnect to the multimedia on-demand server, and frequent reconnection may cause that the working thread of the streaming media player cannot be recovered, which greatly consumes thread resources, so that the working thread of the streaming media player needs to be recovered when the streaming media playing fails, and the streaming media player is allowed to reconnect to the multimedia on-demand server after the communication between the mobile terminal and the multimedia on-demand server is normal. The process of determining whether the communication between the mobile terminal and the multimedia on demand server is normal is prior art and will not be described in detail here.
In the invention, because the picture file and the audio and video file are played after being downloaded to the mobile terminal, and the multimedia on demand server may update the picture file and the audio and video file resources stored in the multimedia on demand server, the mobile terminal needs to compare the downloaded multimedia file with the multimedia file stored in the multimedia on demand server regularly and download the multimedia file to be updated, and the specific downloading and updating method comprises the following steps:
here, the updating operation is performed only when the mobile terminal detects that the media file in the multimedia on-demand server changes, the detection process is very short, and the data volume can be basically ignored relative to the data; for the process of downloading the multimedia file, the consumption is only network transmission and data storage, and compared with the multimedia on demand system, the consumption mainly comes from the decoding and graphic rendering of the multimedia file, so the updating process of the multimedia file does not affect the playing process at all.
The mobile terminal sends a request for inquiring the schedule to the multimedia on demand server periodically, for example, every 5s, the multimedia on demand server returns a schedule list, and the mobile terminal compares the multimedia files in the received schedule list with the multimedia files downloaded and stored by the mobile terminal, for example: twenty-five folders for storing picture files in the schedule list, the folders downloaded by the mobile terminal before are the first and the twelfth, namely: the mobile terminal only selects the first folder and the twelfth folder for playing before, at the moment, the mobile terminal needs to compare the contents in the updated first folder and the twelfth folder in the scheduling list with the contents in the originally downloaded first folder and twelfth folder, and when the contents are determined to be updated or newly added, the updated or newly added contents are downloaded again from the multimedia on-demand server and stored; the updating process of the audio and video files is the same as that of the picture files.
Furthermore, considering the unstable factors such as abnormal packet loss of the wireless network, which may cause the connection interruption between the mobile terminal and the multimedia on demand server at any time, the multimedia on demand server of the present invention monitors the running state of the mobile terminal in real time through the timed heartbeat report mode of the mobile terminal, and saves the session information of the mobile terminal in time when the mobile terminal is in abnormal conditions such as network disconnection, so that the mobile terminal does not need to log in again after being connected with the network again, the flow interaction between the mobile terminal and the multimedia on demand server is reduced, and the operation before network disconnection is continuously executed.
