Method and set-top box that assurance program provided by the invention is play continuously have the following advantages:
1. make full use of the internal memory of set-top box, need not to increase the outer expense of hard disk or server single-candidate;
2. because the internal memory of set-top box is less, therefore, the data of general storage are all few, only as interim storage, and in fact, when the client watches TV programme, the little meeting of many times just leaving, and the TV programme that will store in the so short time is less, therefore is well suited for adopting internal memory to store.Data just because of storage are few, therefore adopt the method for quickening broadcast, guarantee the continuity of program.
Description of drawings
Fig. 1 is a workflow diagram of the present invention.
Embodiment
The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
Be illustrated in figure 1 as workflow diagram of the present invention.
Step 1: set-top box is stored in the TV programme that receives from program source the internal memory, takes out TV programme then and play from internal memory;
Step 2: in the time of when the user televiews by set-top box, need midway leaving, in order not miss the highlight that leaves during this period of time, can press the Pause key of remote controller, then set-top box receives program time-out play command, stop to take out from internal memory TV programme, simultaneously, the TV programme that continues to receive from program source still is stored in the internal memory, be that set-top box begins recording TV program, and data recording is kept in the internal memory;
Step 3: after the user returns, by determining that key continues to play, then set-top box receives program continuation play command, for the progress that falls behind during catching up with, then adopt 4 times of speed or 8 times of speed of normal tv playing programs speed to play, the TV Festival destination data of storing in internal memory drops to pre-set threshold.
Existing set-top box with recording function all be to adopt whole TV programme storage normal speed to play then, but such broadcast mode needs bigger memory space, stores while could play like this.If restart but the user repeatedly suspends, the then data increase that can not stop, this needs bigger memory space just can realize.
But the method that the present invention adopts, owing to just be stored in internal memory, the space of internal memory is less, can not the too many data of storage.Therefore adopt the method for quickening broadcast, prevent the redundancy of data on the one hand, on the other hand,, therefore quicken broadcast and can't watch program to cause bigger influence the user because the data that will play again are few.
Threshold value can be determined according to following mode:
Set-top box is when the normal play TV programme, and the mean value of the TV Festival destination data that statistics is stored in internal memory is as threshold value.
Because after set-top box receives program time-out play command, the TV Festival destination data of storing in the internal memory can sharply increase, in order to get rid of interference to the threshold value accuracy, therefore when receiving program, set-top box suspends play command, then stop to add up the TV Festival destination data of storing in the internal memory, continue play command when set-top box receives program, the TV Festival destination data of storing in internal memory drops to pre-set threshold, then adds up the TV Festival destination data of storing in the internal memory again.
Certainly, this threshold value also can preestablish by experience.Also can be set at the percentage of internal memory.
For example, in save as 256M, when normal play, because continuous received television program and playing, the data of depositing in internal memory can be float value, but by calculating mean value, such as one hour, can draw a mean value, as 30M, can be threshold setting 30M then.
Suspend play command when set-top box receives program, then threshold value still is set at 30M, need not to change.When set-top box receives after program continues play command, owing to adopt doubly speed to play, so the data in the internal memory can reduce, and when reducing to 30M, then adopt original normal speed forward.With this is basic point constantly, adds up the storage data of internal memory in hour once more, and calculating mean value, obtains a new threshold value, as 29M, then with 29M as a new threshold value.
