Fig. 1 is the building-block of logic of apparatus of digital television receiving embodiment one of the present invention;
Fig. 2 is the flow chart of the method embodiment one of apparatus of digital television receiving sectional drawing of the present invention.
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.
As shown in Figure 1, in the building-block of logic of apparatus of digital television receiving embodiment one of the present invention, this apparatus of digital television receiving comprises central processing unit 100, erasable programmable memory (hereinafter to be referred as memory) 101, timer 102, sectional drawing module 103 and input module 104, wherein, memory 101, timer 102, sectional drawing module 103 and input module 104 are connected with central processing unit 100 respectively, will be described in detail various piece below:
Memory 101 stores the sectional drawing option, and described sectional drawing option comprises: entry condition, blanking time, recording time, working channel and mode of operation, and wherein, the entry condition option comprises: come into force, next time start comes into force, specifies come into force start-up time; The mode of operation option comprises visible mode, stealth mode, and visible mode is meant that the demonstration task is carried out on the screen of apparatus of digital television receiving, and stealth mode is the task executions situation that do not show on the screen;
Input module 104 is used to be provided with the sectional drawing option, input module can be OSD, direction increasing-and-decreasing key by graphic user interface comes the respective option in the sectional drawing option is provided with, for example, between the respective option of sectional drawing option, switch to choose certain option by up and down arrow keys, then the option of choosing is provided with, is specially: during " entry condition " option, can between three options of entry condition, switch in elected by the left and right directions key; In elected during " blanking time " option, can first select time unit, as second, branch, the time, import the numerical value of blanking time then, as 8,3 etc.; In elected during " recording time " option, can first select time unit, as minute, the time, the sky, import recording time numerical value then; In elected when " working channel ", can be chosen in and broadcast channel or input specified channel number, number be 2 as the specified channel of input; When " mode of operation ", can select visible mode or stealth mode in elected;
When apparatus of digital television receiving is worked, at first, judge that whether entry condition comes into force, and is specially: entry condition is " next time, start came into force ", promptly judges whether start; Whether entry condition is " specify start-up time come into force ", because apparatus of digital television receiving all carries crystal oscillator, can be consistent with extraneous clock, judge therefore whether entry condition comes into force promptly to judge and specify arrive start-up time; Entry condition is " coming into force ", thinks that promptly the current time entry condition comes into force.
Then, after entry condition comes into force, central processing unit 100 starts timer 102 beginning fixed time interval time and recording times, in recording time, central processing unit 100 control sectional drawing module 103 was once gathered the picture of working channel present frame every a blanking time, to being stored to memory after its name, be specially: at the working channel option is when broadcasting channel, central processing unit 100 is received the instruction of timer arrival 102 blanking times, send the control command of sectional drawing then to sectional drawing module 103, sectional drawing module 103 reads the picture data of present frame in the screen buffer, and according to current time spanned file name, the picture data with present frame writes specified file then; Working channel with broadcasting channel when inconsistent, be 1 for example broadcasting channel, working channel number is 2, after entry condition comes into force, central processing unit 100 writes tuner with channel 2 corresponding channel frequencies, the video code flow of tuner receiving channels number 2 correspondences, and deposit it in screen buffer, when central processing unit 100 is judged when arriving blanking time, send the control command of sectional drawing to sectional drawing module 103, sectional drawing module 103 reads the picture data of present frame in the screen buffer, and according to current time spanned file name, the picture data with present frame writes specified file then.Finished the collection of a frame picture data like this.
After the collection of finishing a frame picture, wait for a blanking time, gather the next frame picture again, finish up to recording time.
In addition, also can be provided with by input module 104 first the respective option to the sectional drawing option before starting sectional drawing, for example be provided with: be 18:00 on January 1 start-up time; Be 5 seconds blanking time; Recording time is 1 hour; Working channel is 2; Mode of operation is a visible mode.
Should be noted that, present embodiment only is used to explain the present invention, for example timer 102 is that the picture data of the present frame that is external in central processing unit, gathered is named according to time corresponding, but present embodiment also is not used in qualification the present invention, for example, timer 102 also can be built in central processing unit, also can adopt alternate manner to come the picture data of present frame is named, for example, sequence numbers etc., the description in its operation principle and the foregoing description is similar, does not do at this and gives unnecessary details.
In the flow chart of the sectional drawing method embodiment one of the apparatus of digital television receiving shown in Fig. 2, may further comprise the steps:
S101. receive the configuration information of input module, described configuration information comprises entry condition, blanking time, recording time, working channel and the mode of operation that the sectional drawing option is set; For example, can select the sub-option in the following option, the sub-option under " entry condition " option: come into force, next time start comes into force, specifies come into force start-up time; Sub-option under " mode of operation " option: visible mode, stealth mode; Sub-option under " working channel " option: broadcasting channel, specified channel; The concrete numerical value of following option can be set, the channel of " specified channel " option; The time value of " blanking time " option; The time value of " recording time " option;
S102. the described configuration information of step S101 is stored to memory;
S103. judge and specify whether arrive start-up time, for example, specify be set to 18:00 on January 1 start-up time, judge by crystal oscillator January 1, whether 18:00 arrived, if not, repeated execution of steps S103; If then change step S104;
S104. central processing unit startup timer comes fixed time interval time and recording time, at first timer is resetted, and the count value with blanking time and recording time writes timer respectively then;
S105. judge whether recording time arrives, promptly judge whether will finish to record, if, then finish, if not, then change step S106;
S106. judge whether arrive blanking time, if then change step S107; If not, then repeated execution of steps S106 promptly waits for blanking time;
S107. timer resets, and retimes blanking time;
S108. the picture data of sectional drawing module collecting work channel present frame;
S109. store the picture data of present frame, and with the current time be according to the spanned file name, change step S105 then, repeated execution of steps S105～S109 arrives up to recording time.
In embodiments of the invention two, entry condition selects start next time to come into force, and then step S103 is for judging whether start, and the description among all the other steps and the embodiment one is similar, does not do at this and gives unnecessary details.
In embodiments of the invention three, entry condition is selected to come into force, and then can omit step S103, and the description among all the other steps and the embodiment one is similar, does not do at this and gives unnecessary details
