Need to prove, in this step, that sets up between set-top box and the terminal equipment is connected to network connection, the network that uses between set-top box and the terminal equipment can be cable network, for example, IP (Internet Protocol, iso-ip Internetworking protocol ISO-IP) network, it also can be wireless network, for example, WiFi (Wireless Fidelity, Wireless Fidelity) network, the technical staff is the network connection between selector top box and the terminal equipment as the case may be, is not specifically limited in the present invention.

S12, the tuning resource query instruction that the set-top box receiving terminal apparatus sends, described tuning resource query instruction are used for the enquiry machine top box and whether have the tuning resource that terminal equipment can be used.

At first need to prove, set-top box needs digital TV tuner to obtain the TS data of digital television program, and usually, each digital TV tuner only can obtain the TS data of the digital television program of a channel.In the embodiment of the invention, the digital TV tuner in the set-top box is called tuning resource, is provided with a plurality of digital TV tuners in the set-top box, be i.e. the tuning resource of many groups.

In a set-top box, the number of digital TV tuner is limited, and namely tuning resource is limited.Be subject to the restriction of tuning resource, if the same time, a plurality of terminal equipments are wanted to play digital television program by set-top box, the insufficient situation of tuning resource of set-top box may occur.

For this situation, after set-top box and terminal equipment are set up network connection, terminal equipment at first sends tuning resource query instruction to set-top box, and described tuning resource query instruction is used for inquiring about described set-top box and whether has the tuning resource that described terminal equipment can be used.

S13, according to the tuning resource query instruction that receives, set-top box is determined the current tuning resource that terminal equipment can be used that whether has.

In this step, set-top box is according to the tuning resource query instruction that receives, determine the current tuning resource that terminal equipment can be used that whether has, and in one embodiment of the invention, can be according to the result who determines, send tuning resource state information to terminal equipment, this tuning resource state information has indicated set-top box whether to have the tuning resource that described terminal equipment can be used.If tuning resource state information has indicated set-top box not have the tuning resource that terminal equipment can be used, the user can resend playing request and parameter to terminal equipment, again to inquire whether have available tuning resource at present, perhaps, the user abandons playing TV programme at this terminal equipment.

S14, when set-top box determine current when having the tuning resource that terminal equipment can use, playing request and the play parameter of the digital television program that the set-top box receiving terminal apparatus sends.

In this step, when set-top box is determined the current tuning resource that terminal equipment can be used that has, when the user starts the digital television program playing function of terminal equipment, set-top box will receive this playing request and play parameter, namely, terminal equipment informs that by this playing request and play parameter STB terminal equipment asks the digital television program of playing, for example, this playing request and parameter are used for informing the digital television program of set-top box users appointment broadcast, usually can comprise the parameters such as channel of the digital television program channel of user selection.

In one embodiment of the invention, result that can be definite according to tuning resource query instruction, send tuning resource state information to terminal equipment, if tuning resource state information has indicated set-top box to have the tuning resource that terminal equipment can be used, terminal equipment will send playing request, have in the indication of tuning resource state information in the situation of the tuning resource that terminal equipment can use, set-top box receives playing request and the parameter of the digital television program that terminal equipment sends.

S15, set-top box is according to playing request and play parameter, uses the TS data of the tuning resource acquisition digital television program that terminal equipment can use.

In this step, concrete, set-top box is according to playing request and play parameter, the channel of corresponding digital television program in locking playing request and the play parameter, carrying out the digital television protocol stack switches, and obtain the TS data from this digital television protocol stack, and from these TS data, filter the audio, video data of non-current channel, keep complete PSI (Program Specific Information, the special information of program)/SI (Service Information, business information) audio, video data of data and current channel, thus get access to the TS data of digital television program corresponding to playing request and play parameter.

Be understandable that, if do not specify out the TV programme that will play of user selection in playing request and the parameter, set-top box can be according to the TS data that set in advance the digital television program channel that obtains acquiescence, and set-top box can also be obtained the TS data of the last digital television program channel of playing of this terminal.

Need to prove, set-top box is obtained the mode of the TS data of digital television program can be same as the prior art, is not described further here.

S16, set-top box sends the TS data that it obtains to terminal equipment, so that terminal equipment is play digital television program.

After terminal equipment receives these TS data, will be according to this TS data playback digital television program.

The method that the digital television program that the embodiment of the invention provides is shared, after set-top box and terminal equipment were set up network connection, terminal equipment sent the resource query instruction to set-top box and whether has a tuning resource that described terminal equipment can be used so that definite set-top box is current; Next, terminal equipment sends playing request and the parameter of digital television program to set-top box, so that set-top box is obtained the TS data of digital television program; Set-top box sends this TS data to terminal equipment after obtaining the TS data of digital television program, so that terminal equipment is according to this TS data playback digital television program.Therefore, the user can realize sharing digital television program at the terminal equipment except the television set of junctor top box.

Optionally, in order to guarantee the fail safe of transfer of data, in one embodiment of the invention, obtain the transport stream TS data of digital television program in step S13 set-top box after, before step S14 set-top box sent the TS data to terminal equipment, the method was further comprising the steps of:

Set-top box is encrypted processing to the TS data of obtaining;

In this case, step S14 set-top box comprises to terminal equipment transmission TS data:

Set-top box sends TS data after the encryption to terminal equipment.

Be understandable that, set-top box before sending these data, need to be carried out caching process to these TS data usually after the TS data of obtaining are encrypted processing, and set-top box sends the data of buffer memory to terminal equipment afterwards.

Be understandable that, in one embodiment of the invention, terminal equipment can with tuning resource be the tuning resource of current free time of set-top box.

Further, for the tuning resource that solves on the set-top box inadequate, can not effectively guarantee the problem that terminal equipment can the normal play digital television program, a kind of priority scheduling strategy of tuning resource is provided in the embodiment of the invention, below this priority policy is elaborated:

At first, for each can watch that the terminal equipment of digital television program arranges a priority by set-top box, the priority of each terminal equipment can be identical or different, for example, according to grade from high to low, priority can be divided into franchise priority, limit priority, inferior high priority, normal priority, inferior low priority, lowest priority etc., and the present invention is not construed as limiting at this.

When the tuning resource query instruction that receives certain terminal equipment, whether set-top box will at first inquire about available free tuning resource, if current do not have an idle tuning resource, set-top box will be according to the priority of this terminal equipment, and whether inquiry has the tuning resource that the other-end equipment except idle tuning resource can be used.

In this case, terminal equipment can with tuning resource can comprise idle tuning resource, also comprise at least a in the tuning resource that tuning resource that terminal equipment can take and terminal equipment can share.Wherein, the tuning resource that terminal equipment can take is for distributing to the tuning resource that priority is lower than the other-end equipment of this terminal equipment, the tuning resource that terminal equipment can share is for to distribute to the tuning resource that priority is not less than the other-end equipment of this terminal equipment, and the other-end equipment that described priority is not less than this terminal equipment comprises that priority is higher than and/or is equal to the other-end equipment of this terminal equipment.

In one embodiment of the invention, terminal equipment can with tuning resource comprise the tuning resource that idle tuning resource and terminal equipment can take.Terminal device prioritizes is used idle frequency modulation resource, if without idle frequency modulation resource, terminal equipment can take other of priority that priority is lower than it and distribute the frequency modulation resource of the terminal equipment of tuning resource, has distributed the frequency modulation resource of the terminal equipment of tuning resource but cannot take other of priority that priority is higher than it.Suppose to be provided with franchise priority, the tuning resource that the terminal equipment of franchise priority distributes cannot be shared by other-end equipment.

In one embodiment of the invention, terminal equipment can with tuning resource comprise the tuning resource that idle tuning resource and terminal equipment can share.Terminal device prioritizes is used idle frequency modulation resource, if without idle frequency modulation resource, terminal equipment can share other of priority that priority is not less than it and distribute the frequency modulation resource of the terminal equipment of tuning resource.Need to prove, if and other have distributed the terminal equipment of tuning resource to share the frequency modulation resource, that terminal equipment is play is that it shares, distributed the digital television program of the current broadcast of terminal equipment of tuning resource, and the program that can not affect this terminal equipment that has distributed tuning resource is play.
