The method flow diagram of the split screen display video that Fig. 3 provides for the another embodiment of the application, its concrete steps are as follows:
Step 301:IPTV server obtains all programme informations that streaming media server provides, and all programs that convection media server provides are classified.
Particularly, IPTV server can according to common program classification mode, and all programs that convection media server provides are classified, and such as, are categorized as: love class program, war class program, amusement class program, sport category program etc.
Step 302:IPTV server, for each program category, sorts to all programs under this program category, generates the program sorted lists of this program category.
Different ordering rules can be adopted for different program categories, ordering rule such as:
One) popular sequence, namely adds up the video-on-demand times of each program respectively, according to video-on-demand times from more to less, sorts to program;
Two) show time sequence, namely according to each program show time from the close-by examples to those far off, program is sorted;
Three) star's films and television programs time-sequencing, namely first classifies to program according to the difference of star further, then to the program of each star, then according to each program show time from the close-by examples to those far off, program is sorted;
Four) direct films and television programs time-sequencings, namely first according to the difference of director, program classified further, then to the program of each director, then according to each program show time from the close-by examples to those far off, program is sorted.
Need to preset the ordering rule of the program under each program category, such as: star's films and television programs time-sequencing rule is adopted for love class program settings, popular ordering rule is adopted for amusement class program settings, etc.
Program sorted lists take program category as index, and the content of program sorted lists comprises: configuration file URL (Uniform Resource Locator, Uniform Resource Identifier) address, the program description etc. of each program.Program description is as programm name, video-on-demand times etc.
Step 303:IPTV server receives the registration request that IPTV client is sent, the information such as IP address, physical port number of this IPTV client is carried in this request, IPTV server is verified according to the IP address, physical port number etc. of this IPTV client, be verified, return the registration response indicating and succeed in registration to IPTV client.
The registration response that the instruction that step 304:IPTV client reception IPTV server returns is succeeded in registration, is divided into the display screen of self: video shows boss's split screen, video shows sub-split screen and video file information shows sub-split screen three part.
Particularly, IPTV client can be given tacit consent to and is divided into by the display screen of self: video display boss split screen, two each and every one videos show sub-split screen and a video file information shows sub-split screen; Or the video display boss split screen that IPTV client is inputted by telecontrol panel according to user, video show the display screen of number to self that sub-split screen and video file information show sub-split screen and divide.Usually, split screen number does not exceed 6, to avoid eye strain.
After split screen, the Aspect Ratio that video display boss's split screen and video show sub-split screen remains unchanged, and this Aspect Ratio is identical with the Aspect Ratio of the display screen of IPTV client usually.
The area of video display boss split screen is greater than the area that video shows sub-split screen, watches to facilitate user.
The display screen that Fig. 4 gives IPTV client carries out the exemplary plot after split screen division.
The program that before acquiescence plays split screen when video display boss split screen is initial, the display screen of IPTV client is play.
Video file information show sub-split screen initial time the acquiescence display video display boss split screen information of program play, as programm name, featured performer, program category, program playing duration, subsequent period TV guide title etc.
Step 305:IPTV client shows display program tabulation on sub-split screen at each video, when detect user arbitrary video show sub-split screen chooses a program classification time, programme type identification user chosen sends to each video to show self adaptation corresponding to sub-split screen and flows down a year middleware, each self adaptation flows down carries middleware respectively to IPTV server transmission URL Address requests, carry this programme type identification and program sequence number in this request, program sequence number is that this self adaptation flows down the sequence number of carrying video corresponding to middleware and showing sub-split screen.
Each video shows the corresponding self adaptation of sub-split screen and flows down a year middleware, and a video display boss split screen also corresponding self adaptation flows down a year middleware.
The sequence number that video shows sub-split screen is followed successively by: 1,2,3,4 ..., n, n be the number that video shows sub-split screen.
Step 306:IPTV server receives arbitrary self adaptation and flows down the URL Address requests of carrying middleware and sending, the programme type identification carried according to this request finds the program sorted lists of this program category, according to the program sequence number that this request is carried, in this sorted lists, find the configuration file URL address of corresponding program, this configuration file URL address is returned to this self adaptation and flow down a year middleware.
Such as: if the program sequence number of carrying in URL Address requests is m, 1≤m≤n, then IPTV server finds the configuration file URL address of the program coming m position in program sorted lists, this configuration file URL address is returned to this self adaptation and flows down a year middleware.
Arbitrary self adaptation of step 307:IPTV client flows down the URL address of carrying middleware reception IPTV server and returning, download the configuration file of corresponding program from streaming media server according to this URL address, preserve this configuration file, and the URL address of video source according to the lowest bitrate of this program recorded in this configuration file, download the video flowing of the video source of the lowest bitrate of this program from streaming media server, this video flowing is shown on sub-split screen at the video of correspondence and plays.
