Fig. 2 is the signaling process figure of the TSTV control method for playing back of the embodiment of the invention two.In the embodiment of the invention two, to adopt before the above-mentioned control method for playing back, it is example that set-top box is in live state.Concrete application scenarios is, the current live signal of playing of set-top box, TSTV user uses set-top box to watch live TV programme, in the case, if TSTV user need to watch the program of having play before the current time, then can carry out Play Control according to flow process as shown in Figure 2.As shown in Figure 2, the method comprises following process.
At first, adopt the TSTV control method for playing back of the embodiment of the invention two, before the user assigns the Play Control order, need to carry out first following steps 201 to step 205, carry out pre-configured to the equipment in the TSTV system.
Step 201: the programme information of content management system stores time shifting channel information and time shifting channel.
In this step, can create time shifting channel at Content Management System by TSTV system maintenance personnel, and the programme information of time shifting channel information and time shifting channel is set, Content Management System is stored the time shifting channel information that arranges and the programme information of time shifting channel.
Step 202: Content Management System sends time shifting channel to the VOD server request message is set.
In this step, Content Management System arranges the time shifting channel information that comprises storage in the step 201 in the request message to the time shifting channel of VOD server transmission.
Step 203:VOD Servers installed time shifting channel.
In this step, the VOD server arranges time shifting channel according to the time shifting channel information that time shifting channel arranges in the request message.
Step 204: Content Management System is to the programme information of two-way EPG server sync time shifting channel information and time shifting channel.
In this step, Content Management System is to the programme information of the time shifting channel of two-way EPG server sync, might be the time shifting channel programme information according to the time sequencing ordering, also might be the time shifting channel programme information that does not sort according to time sequencing.
Step 205: the programme information of two-way EPG server stores time shifting channel information and time shifting channel.
In this step, the programme information of the time shifting channel of two-way EPG server stores is the time shifting channel programme information according to the time sequencing ordering.Particularly, step 205 comprises two kinds of situations.Situation one: if Content Management System is programme information according to the time shifting channel of time sequencing ordering to the programme information of the time shifting channel of two-way EPG server sync in the step 204, then in step 205, two-way EPG server is the programme information according to the time shifting channel of time sequencing ordering obtained from Content Management System of storage directly.Situation two: if Content Management System is not according to the programme information of the time shifting channel of time sequencing ordering to the programme information of the time shifting channel of two-way EPG server sync in the step 204, then two-way EPG server at first to the programme information of the time shifting channel that obtains from Content Management System according to time-sequencing, obtain the programme information according to the time shifting channel of time sequencing ordering, then store the programme information according to the time shifting channel of time sequencing ordering of obtaining after the above-mentioned ordering.
Above-mentioned steps 201 to step 205 can be carried out behind the opening of device such as foregoing management system, VOD server, two-way EPG server and set-top box immediately, the moment that also can after the said equipment is opened, determine to trigger execution by TSTV system maintenance personnel, but must before above-mentioned steps 206, finish execution in step 201 to the process of step 205.Then, carrying out above-mentioned steps 201 to step 205, when TSTV user uses set-top box to watch live TV programme, set-top box is in live state, if this moment, TSTV user need to watch the program of having play before the current live time, then can send program redirect signal to set-top box, enter following steps 206.
Step 206: set-top box is obtained program redirect signal.
In this step, the program redirect signal that obtains of set-top box is that TSTV user issues.Particularly, the remote controller that TSTV user can be by set-top box or be arranged on triggering key on the set-top box sends program redirect signal to set-top box.In the embodiment of the invention two, the user issues program redirect signal when watching programme televised live, therefore this program redirect signal can only point to the program of having play before the current live time, the current live time is the standard time of TSTV system, for example, the standard time of TSTV system is 10:00 in the morning, and then the current live time is 10:00 in the morning, program redirect signal can only point to the program of having play before the 10:00 in the morning, for example the morning 9:00 program.The program redirect signal that the user issues is used to indicate this user and wishes the target program that jumps to.Playing is separated by specifies the program of number to this target program in order to return from current program.For example, when specifying number to be 1, this target program is a upper program of current program, in the case, a kind of better execution mode is, TSTV user can be arranged on the remote controller or is arranged on " a upper program " button on the set-top box by pressing, and issues program redirect signal to set-top box.This specifies number can also be for greater than other integer of 1, for example, when specifying number to be 3,3rd program of this target program for having play before broadcasting at current program, in the case, a kind of embodiment is, can be on remote controller or set-top box the button of " return and specify the number program " is set, " returning 2 programs " button for example is set respectively, the button etc. that " returns 3 programs ", the user can be according to the desired program of watching and current program number apart, press corresponding button, for example press " returning 3 programs " button, issue program redirect signal to set-top box; Perhaps, another kind of embodiment is, can at remote controller " returning " key and the numerical keys such as " 1 ", " 2 ", " 3 " be set, the user can be according to the desired program of watching and current program number apart, press successively " returning " key and corresponding numerical key, for example press successively " returning " key and " 3 " key, issue program redirect signal to set-top box.
Step 207: set-top box sends target programme information request message to two-way EPG server.

When the target program of the program redirect signal designation that obtains when set-top box in the step 206 is play the number of being separated by greater than 1 program for returning from current program, for example the target program is the 3rd program that current program is play before, set-top box not only comprises in the target programme information request message of two-way EPG server transmission: redirect directioin parameter, channel ID and current reproduction time, and comprise: redirect program number.For example, if the target program is the 3rd program that current program is play before, then redirect program number is 3.
Step 208: two-way EPG server obtains the time started information of target program according to target programme information request message.
In this step, two-way EPG server according to the concrete grammar that target programme information request message obtains the time started information of target program is: at first, two-way EPG server is according to the channel ID in the target programme information request message and current reproduction time, the programme information according to the time shifting channel of time sequencing ordering of inquiry storage is obtained the time started information of current program.After getting access to the time started information of current program, comprise two kinds of dispositions: be the situation of a upper program for the target program, two-way EPG server is according to the time started information of the redirect directioin parameter in the target programme information request message and current program, the programme information according to the time shifting channel of time sequencing ordering of inquiry storage, obtain time started information on the redirect direction and current program and be divided into mutually 1 time started information, as the time started information of target program.For the target program for return the situation of number greater than 1 program of being separated by of playing from current program, two-way EPG server is according to the time started information of redirect directioin parameter, redirect program number and current program, the programme information according to the time shifting channel of time sequencing ordering of inquiry storage, obtain time started information on the redirect direction and current program and be separated by and specify the time started information of redirect program number, as the time started information of target program.
Further, after two-way EPG server obtains the time started information of current program, in the time started information of the programme acquisition of information target program of the time shifting channel by inquiry storage, can also get access to simultaneously one or more the combination in the following information of target program: heading message, profile information and concluding time information.Step 209: two-way EPG server returns the time started information of target program to set-top box.
In this step, two-way EPG server returns the time started information of target program to set-top box.Further, needs according to practical application, two-way EPG server can also return one or more combination in the following information of target program to set-top box: heading message, profile information and concluding time information in time started information from the target program to set-top box that return.
Step 210: set-top box sends time shift positioning playing request message to the VOD server.
In this step, the time started information of the target program that set-top box is returned according to two-way EPG server sends time shift positioning playing request message to the video on demand server.Set-top box comprises in the time shift positioning playing request message of VOD server transmission: the time started information of target program.Further, needs according to practical application, comprise the time started of target program in the time shift positioning playing request message that set-top box sends to the VOD server when information, can also comprise one or more the combination in the following information of target program: heading message, profile information and concluding time information.
Step 211:VOD server pushes corresponding programme content according to the time started information of target program to set-top box.
In this step, the VOD server at first should programme content corresponding to time started information according to the time started acquisition of information of target program, then pushes this programme content to set-top box.Further, the VOD server can also obtain corresponding programme content according to one or more the combination in the following information of the time started combining target program of target program, comprising: the heading message of target program, profile information and concluding time information.
Step 212: set-top box is play the programme content of VOD server push.
In this step, set-top box is play the programme content corresponding to time started information of the target program of VOD server push.
In the embodiment of the invention two, when set-top box is in live state, the user issues program redirect signal in conjunction with digital keys to set-top box by " a upper program " button or " returning " button, shifting state when set-top box is switched to from live state, set-top box is obtained first the time started information of target program from two-way EPG server by target programme information request message, obtain programme content corresponding to this time started information according to the time started information of target program from the VOD server again, thereby can play-over the required program of watching according to the program order, thereby improved the Play Control efficient of TSTV, and the flexibility that has improved the Play Control of TSTV.
