Please refer to shown in Figure 1ly, digital TV direct playing and playback system of the present invention comprises front end system 1, radio network 2 and two-way interactive network 3 and user's receiving terminal 4.Wherein front end system 1 is the core of digital TV direct playing and playback system; Radio network 2 is the cable TV transmission network network, and two-way interactive network 3 can be the Internet in the cable modem, also can be outer mutual network such as Ethernet or ADSL, digital TV set-top box or the digital TV integrated machine of user's receiving terminal 1 for having back transfer interface and direct playing and playback module.
Please refer to shown in Figure 2, the reciprocal process of set-top box and digital TV direct playing and playback system front end is as follows: when the user need suspend current in progress programme televised live, the set-top box forward end sends suspends request command, and institute's art request command includes the information of the information of indicating the user identity numbering, current program transport streams numbering and the information of the professional numbering of current program.After front end is received the time-out request instruction of set-top box, whether this programme televised live is recorded in the Query Database, and the title of the video file of recording, contrast relationship between the video file of noting the set-top box request and recording, and distribute the video server resource for the user, from video server, obtain the parameter of broadcast program simultaneously, send to suspend to set-top box and ask answer instruction notification set-top box to prepare to watch this program.When the user need begin again broadcast program from the position of suspending, forward end sends again the playing request instruction, after front end is received the instruction of playing request again of set-top box, the request video server begins to play corresponding video frequency program file from the position that user request stops, and replys instruction notification user program by playing request again and has play or asked and be rejected; If the user need carry out fast reverse operation to program, forward end sends the fast rewinding request instruction, after front end was received the fast rewinding request instruction of set-top box, the request video server was play corresponding rewind down file, and replied instruction notification user program by fast rewinding request and play or asked and be rejected; If the user need carry out forwarding operation to program, forward end sends the F.F. request instruction, after front end was received the F.F. request instruction of set-top box, the request video server was play corresponding F.F. file, and replied instruction notification user program by the F.F. request and play or asked and be rejected; If the user will turn back to the programme televised live broadcast state, promptly with the synchronous state of TV station's broadcast program, forward end sends returns request instruction, front end receive set-top box return request instruction after, the request video server stops broadcast program, and be released to the resource that this user distributes, and being accepted by returning request answer instruction notification user request simultaneously, set-top box will switch to original programme televised live voluntarily; If set-top box has been in when watching the direct playing and playback program state, the user sends and suspends request, then the set-top box forward end sends the simple request instruction that suspends, front end system can suspend the program of current broadcast after receiving this instruction, and sends and suspend request and reply instruction notification user request and adopted.
When the user directly asks fast reverse operation when watching programme televised live, then the automatic forward end of set-top box sends continuously and suspends request instruction, playing request instruction and three instructions of fast rewinding request instruction again, and receives to handle after sending every instruction and reply instruction accordingly and can realize fast reverse play; Directly the request forwarding operation is under an embargo and ignores when the user watches programme televised live, and is same, and the request pausing operation also is under an embargo and ignores when the user is in F.F. or rewind down state.
Please refer to shown in Figure 3ly, set-top box end program handoff procedure is as follows: the every forward end of set-top box is sent a request, must wait for replying of front end system, reply if can not receive, then to judge whether repeat to send this request,, then will carry out timeout treatment if reach maximum number of repetitions.
Set-top box is after instruction is replied in the time-out request of receiving front end, do not carry out program switches at once, and it is just that in progress program is static, wait for that the user further operates, have only after the user sends again the playing request instruction and receives that again playing request is replied instruction, just carry out program and switch, the program that the user can watch video server to play for this user.
During the user watches the program of video server for this user's broadcast, the user can carry out F.F., fast reverse operation at any time, video server is after receiving user's F.F., fast reverse operation instruction, can play and the corresponding F.F. of this program, rewind down file at original passage, user side does not need to carry out program and switches, and directly can watch F.F., rewind down program.The user will turn back to the normal play state from F.F., rewind down action, must send again playing request instructs to front end system, front end system is after receiving this instruction, can calculate the position of rewind down, forwarding operation end, and instruct video server begins from this position of this program to play, user side does not need to carry out program yet and switches, and directly can begin to watch this program from appointed positions.
When the user will be when the direct playing and playback state turns back to the programme televised live state, forward end sends returns request instruction, front end will discharge the resource that video server distributes for this user after the request of the end direct playing and playback state of receiving user side, notify the user to turn back to original programme televised live simultaneously.
Please refer to shown in Figure 4, the playing programs process of front end system is as follows, when front end system gets the command process server and receives user's time-out request command, at first search for program corresponding recording file with user's request, if this program is not recorded, then send the refusal instruction, user's request failure to the user.After finding recorded file, to position file, determine that the user sends the position in the instruction moment respective file, then to video server application channel resource, if passage application success then returns mutually deserved parameter to the terminal use, and notifies the user to ask to get the Green Light, otherwise, send the unaccepted instruction of request to the user.Notice that at this moment video server does not have real broadcast program, and just channel resource is kept to this user, front end system began and can regularly communicate with the user from this moment, to guarantee that the user also is in active state, if in case find that the user can't get in touch with, front end system can think that the user has shut down or interrupted communication link, and front end system can begin reprocessing work such as resource release automatically.
When front end system receives that the user is again during the playing request order, command process server notification video server is play the program of this user's request on the passage that this user applied for, the i.e. program file that when handle suspending request instruction, finds and definite position, if play instruction runs succeeded, then the request of announcement machine set-top box customer is accepted, otherwise sends the refusal instruction to the user.
When front end system is received user's F.F. or fast rewinding request instruction, at first search for the F.F. or the rewind down file of this program correspondence, if file not found, then send the refusal instruction, otherwise, in F.F. or rewind down file, find position, and the notice video server stops to play current program file on the passage that this user applied for the document location correspondence of current broadcast, begin to play F.F. or the rewind down file that finds from correct position, notify the user to ask to be accepted simultaneously.When program F.F. or rewind down arrive the afterbody of program or head, F.F. or rewind down action will stop automatically, wait for user's further operation.
Under F.F. or rewind down state, when front end system is received user's the instruction of playing request again, the command process server at first notifies video server to stop broadcast program on the passage that this user applied for, and F.F. or rewind down document location correspond to program file will stop to play the time, and beginning the broadcast program file from this position, the request of announcement machine set-top box customer is accepted then.
Under any state, when front end system receives that the user returns request instruction, command process server notification video server stops broadcast program on the passage that this user applied for, and discharges the channel resource that this user applies for, announcement machine set-top box customer request simultaneously is accepted.
The electronic program guide information that the programme televised live acquisition system carries according to programme televised live, automatically program is recorded, then according to the event information in the Event Information Table, generate the performance recording planning chart, and record corresponding program file according to recording planning chart, comprised information such as channel designation, date, programm name in the name of program file.The programme televised live acquisition system allows operating personnel to intervene and revises the performance recording plan, reason is that electronic program guide information is inaccurate sometimes, programme televised live might be postponed or in advance, at this moment operating personnel can carry out manual modification to the performance recording plan, to proofread and correct the performance recording time.System there is no need to keep for each user the copy of a TV programme, but adopt the method for prerecording, the user may TV programme interested and that need record be recorded, and a kind of opposite extreme situations is that system records in the TV programme of broadcasting all.When user's forward end system sends recording request, the program that front end system can guide user capture to prerecord, thereby make all need record the same copy of user capture of same program, and save the hard drive space that the front-end stores server need dispose greatly.
