Abstract
The invention provides a program continuous playing method of a set top box. The program continuous playing method comprises the following steps: encrypting a unique identification code of the set top box and a software code of the set top box by using a pre-set encryption algorithm to obtain a secret key, wherein the unique identification code is used for uniquely identifying the set top box; signing a random number of the secret key through a pre-set signature algorithm to obtain first signature data; writing the unique identification code, the first signature data and the random number into the set top box; when the set top box is started, reading the unique identification code, the software code, the random number and the first signature data; decrypting the secret key by using the unique identification code and the software code, and signing a random number of the decrypted secret key through the signature algorithm to obtain second signature data; judging whether the second signature data is the same as the first signature data or not; if so, starting the set top box. By the aid of the safety protection method, the safety protection can be provided for the set top box.
Description
Technical field
The present invention relates to set-top box technique field, particularly relate to a kind of program Continuous Play method of Set Top Box.
Background technology
Now, set-top box technique development, can watch more abundanter TV programme by Set Top Box.But because network reason there will be transmission delay between current Set Top Box and server, cause Set Top Box to have the loading procedure of blink when playing TV programme, this just causes Set Top Box to exist when switching TV program and plays discontinuous situation.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of program Continuous Play method of Set Top Box, can ensure broadcasting continuity during switching TV program.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of program Continuous Play method providing Set Top Box, comprise: the TV programme play before shutdown is play as current television program by Set Top Box acquiescence when starting shooting, and is stored in buffer area by the next TV programme of described current television program; When the next TV programme that Set Top Box switches to described current television program is to replace described current television program, from described buffer area, takes out the TV programme stored play; When the described next TV programme that described buffer area stores all is taken out, the next TV programme of described current television program is stored in described buffer area by described Set Top Box; When the TV programme that described buffer area has stored all do not taken out and described Set Top Box switch to described current television program next TV programme to replace described current television program time, described Set Top Box deletes the TV programme remaining in described buffer area and do not play, and the next TV programme of described current television program is stored in described buffer area.
Preferably, described buffer area is internal storage or the external memory storage of described Set Top Box.
Be different from the situation of prior art, the invention has the beneficial effects as follows: because Set Top Box is when playing TV programme, the next TV programme of meeting buffer memory current television program, when switching to next TV programme from current television program, can play without the need to loading, and the TV programme next TV programme that buffer memory is new again remaining and do not play is deleted when upper once switching TV program, thus broadcasting continuity when can ensure switching TV program, improve the viewing experience of user.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the program Continuous Play method of embodiment of the present invention Set Top Box.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, it is the schematic flow sheet of the program Continuous Play method of embodiment of the present invention Set Top Box.The program Continuous Play method of the present embodiment comprises:
S1: the TV programme play before shutdown is play as current television program by Set Top Box acquiescence when starting shooting, and the next TV programme of current television program is stored in buffer area.
Wherein, during set-top-box opening, buffer area can be empty, also can be preserve a given data.If preserve a given data, Set Top Box is storing next TV programme after these data being deleted.In the present embodiment, buffer area is internal storage or the external memory storage of Set Top Box.
S2: when the next TV programme that Set Top Box switches to current television program is to replace current television program, takes out the TV programme stored and play from buffer area.
Wherein, because Set Top Box is when switching TV program, need receive from the program source of server and play TV programme, if there is transmission delay, just need to load and could play blink, thus cause broadcasting discontinuous.And the next TV programme of current television program is stored in buffer area in advance, thus after switching TV program, directly take out TV programme from buffer area and play, thus do not need to communicate with service, thus can smooth playing, broadcasting continuity during switching TV program can be ensured.
S3: when the next TV programme that buffer area stores all is taken out, the next TV programme of current television program is stored in buffer area by Set Top Box; When the TV programme that buffer area has stored all do not taken out and Set Top Box switch to current television program next TV programme to replace current television program time, Set Top Box is deleted in buffer area and is remained the TV programme do not play, and the next TV programme of current television program is stored in buffer area.
Wherein, buffer area is due to limited storage space, buffer area is less than the broadcasting speed of TV programme usually stored in the speed of TV programme, so the television programme data that buffer area stores can be fewer and feweri, when TV programme is all taken out, Set Top Box is then direct to be received from program source and plays TV programme, thus allows the imperceptible loading procedure of user, achieves broadcasting continuity.TV programme is all taken out or TV programme is not all taken out, when Set Top Box is switched to next TV programme again, again the next TV programme of current television program is stored in buffer area, so as next time switching TV program time, repeat said process.
By the way, the program Continuous Play method of the Set Top Box of the embodiment of the present invention is when Set Top Box plays TV programme, the next TV programme of meeting buffer memory current television program, when switching to next TV programme from current television program, can play without the need to loading, and the TV programme next TV programme that buffer memory is new again remaining and do not play is deleted when upper once switching TV program, thus broadcasting continuity when can ensure switching TV program, improve the viewing experience of user.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
