Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Please refer to Fig. 1, be the flow chart of the method for embodiment of the invention play multimedia files,
The method of the said play multimedia files of present embodiment comprises:
Step S101 reads preset file, and here, said preset file is for be stored in the equipment and changeless encrypt file in advance.The information that said preset file comprises is multimedia messages or Rule Information; Said multimedia messages comprises that multimedia messages comprises multimedia file address information, play mode information and playing duration information, and said Rule Information comprises the address information of rule file.
Step S102, deciphering is also resolved this document, and file described herein comprises the preset file of encryption and the rule file of encryption.Through encrypting address information and the copyright information thereof that to protect multimedia file, safe and reliable.Before deciphering, need the said file of verification whether to damage; Remind the user if said file corruption then reports an error, otherwise decipher said file, obtain the information that said file comprises.
Step S103 judges whether the information that file comprises is multimedia messages.
Step S104 if the information that said file comprises is multimedia messages, then downloads multimedia file according to said multimedia messages and waits for broadcast.
Particularly, the pattern of play multimedia files comprises live, program request and intercuts.
For example, theing contents are as follows behind the said file decryption:
<?xml?version='1.0'?encoding='UTF-8'?>
<node>
<item>
<playUrl>xxxp://8.8.8.8/allVideo/ad1.avi</playUrl>
</item>
</node>
Explain that then the information that said file comprises is multimedia messages, particularly, comprised the address information of multimedia file in this file.Download multimedia file according to the multimedia file address information in the said multimedia messages; If said multimedia messages also contains play mode information and playing duration information, the pattern and the time of then playing according to the play mode information in the said multimedia messages and playing duration information Control.
S105; If the information that said file comprises is not multimedia messages; The Rule Information that then comprises according to file obtains rule file, and the information that said rule file comprises is multimedia messages or Rule Information, and execution in step S102 and step S103 also constantly circulate until obtaining multimedia messages.
For example, theing contents are as follows behind the said file decryption:
<?xml?version=’1.0’?encoding=’UTF-8’?>
<node>
<item>
<ruleUrl>xxxp://8.8.8.8/allres/rule1</ruleUrl>
</item>
</node>
Explain that then information that said file comprises is not multimedia messages but Rule Information, according to Rule Information visit < ruleUrl >, obtain after the rule file again execution in step S102 and step S103 and constantly circulation until obtaining multimedia messages.
Particularly, when the fileinfo that obtains thes contents are as follows:
<?xml?version='1.0'?encoding='UTF-8'?>
<node>
<item>
<playType>Live</playType>
<playUrl>xxxp://8.8.8.8:8080/allVideo/living?</playUrl>
<playBeginTime>19:00</playBeginTime>
<playEndTime>19:30</playEndTime>
</item>
</node>
Then explain this document requirement the address of < playUrl>is carried out live, and the live time be limited in 19:00 to 19:30 according to < playBeginTime>and < playEndTime >.
When determining documentation requirements certain address is carried out need judging also whether file has other requirement live the time, like the requirement of time, or requirement such as program level.If live is clock news, then when the equipment time reached this integral point, the switching foreground is shown as needed live multimedia messages content.
When the fileinfo that obtains thes contents are as follows:
<?xml?version='1.0'?encoding='UTF-8'?>
<node>
<item>
<playType>Intercut</playType>
<playUrl>xxxp://8.8.8.8/allVideo/ad1.avi</playUrl>
</item>
</node>
After then downloading the multimedia file and storage well of this < playUrl>address, judge the residing running status of current device.If equipment is in the network blockage state, then switch the foreground and show, play the good multimedia file of storage.
When the fileinfo that obtains thes contents are as follows:
<?xml?version='1.0'?encoding='UTF-8'?>
<node>
<playType>Program request</playType>
<item>
<playName>Video 1</playName>
<playUrl>xxxp://8.8.8.8/allVideo/ad1.avi</playUrl>
