Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The present invention is according to the playing programs time point of user's input, send the program request information that comprises this playing programs time point to video server, video server is inquired about the program file of this program request information correspondence from video server or storage-playback according to the program request information that receives, the program file that inquires is adjusted to the playing programs time point that comprises in the program index information, from this playing programs time point this program file is sent to set-top box in the mode of Streaming Media, set-top box receives this program file and plays.
Fig. 1 shows the flow process of the digital television program player method that the embodiment of the invention provides, and details are as follows.
In step S101, receive the program progress monitoring enabled instruction of user's input, display program progress monitoring interface, wherein, this program progress monitoring interface includes the playing programs time point.
In specific implementation process, the user is when normally watching digital television program, and when needs were controlled the program progress, by " time-out " key input program progress monitoring enabled instruction of remote controller, this moment, picture suspended, display program progress monitoring interface.
As embodiments of the invention, this program progress monitoring interface further comprises title, current playing program time started and the current playing program concluding time of slider bar, current playing program.Wherein, this slider bar correspondence time of playing programs.In specific implementation process, when direct playing and playback, the slider bar time corresponding is the playing programs time in the display program progress monitoring interface, and when on-demand playback, the slider bar time corresponding is the relative time of playing programs in the display program progress monitoring interface.
In step S102, judge that whether the program time out surpasses the time limit of system default,, carries out step S103 in limited time when the program time out surpasses system default, the direct playing and playback menu interface is arrived in channel resource recovery or control system, otherwise carry out step S104.
Certainly, step S102 is an independently process, does not influence the carrying out of other steps.
After program progress monitoring interface display, because the scroll bar and the playing programs time at program progress monitoring interface are corresponding, the user can control the reproduction time of current playing program by the scroll bar at control program progress monitoring interface.
In order fully to satisfy the convenience that the user adjusts in the different time scope, can use different step units, for example 1 minute, 2 minutes and 5 minutes.When the user need a few minutes very among a small circle in when adjusting slide block, single gets final product by " F.F. " or " rewind down " key continuously, at this moment step units is 1 minute.If the user need reach scope far away fast, continuable pinning " F.F. " or " rewind down " key, the coding that this moment, remote controller sent is different with the single keys presses coding.5 codings stepping that set-top box is received is 1 minute, and the 6th beginning stepping changes 2 minutes into, and the 11st beginning stepping changes 5 minutes into.That is to say that 5 times " 1 " changes " 2 " afterwards into, 5 times " 2 " change " 5 " afterwards into, have so just reached the effect of " more and more faster ", are step units with time, can accurately navigate to the random time point, are user-friendly to.
As prior art, the user is dragged each time point of scroll bar slide block correspondence, all generate programme information, the tableaux of the corresponding video of time point and showing in video server request video flowing, so that the user observes playing progress rate, whether decision also needs to drag scroll bar.The user regulates playing progress rate by dragging scroll bar, can find out the program progress from scroll bar intuitively, can also pass through the wicket displays program information, is user-friendly to.
In step S104, receive the playing programs time point of user according to the input of program progress monitoring interface.
In step S105, send the program request information of the playing programs time point that comprises user's input to video server.
When video server returns the program file corresponding with program request information, carry out step S106, receive and that broadcast video server returns and the corresponding program file of playing programs time point user's input.
Fig. 2 shows the flow process of the digital television program data transmission method for uplink that the embodiment of the invention provides, and details are as follows.
In step S201, receive the program request information of the playing programs time point that comprises user's input.
In step S202, inquire about the program file of this program request information correspondence according to the program request information that receives.As embodiments of the invention, when inquiring about the program file of this program request information correspondence, from video server or storage-playback, inquire about according to the program request information that receives.
In step S203, the program file that inquires is adjusted to the playing programs time point that comprises in the program index information, from this playing programs time point this program file is sent to set-top box in the mode of Streaming Media.
Fig. 3 shows the structure of the digital television program playing device that the embodiment of the invention provides.
Program progress monitoring interface display control module 11 receives the program progress monitoring enabled instruction of user's input, display program progress monitoring interface, and wherein, this program progress monitoring interface includes the playing programs time point.
Time judgment module 12 judges whether the program time out surpasses the time limit of system default,, the direct playing and playback menu interface is arrived in channel resource recovery or control system in limited time when the program time out surpasses system default.
Playing programs time point information receiver module 13 receives the playing programs time point of user according to the input of program progress monitoring interface, and the user imports the process of playing programs time point and states at preamble, just repeats no more herein.Program request information sending module 14 sends the program request information of the playing programs time point that comprises described user's input to video server.
When video server returns program file, that program file playing module 15 receives and broadcast video server returns and the corresponding program file of playing programs time point user's input.
Fig. 4 shows the structure of the digital television program data sending device that the embodiment of the invention provides.
Program request information receiver module 21 receives the program request information of the playing programs time point that comprises user's input, the program request information that program file enquiry module 22 receives according to program request information receiver module 21 is inquired about the program file of this program request information correspondence, wherein, when carrying out file polling, in video server or storage-playback, carry out.
Program file sending module 23 is adjusted to the playing programs time point that comprises in the program index information with the program file that inquires, and from this playing programs time point this program file is sent to set-top box in the mode of Streaming Media.
The invention solves prior art and in video flowing, locate the complicated and shortcoming consuming time of I frame algorithm, can separate the accurately problem of positioning playing time point, also realized the quick location of coded image with more succinct method.
