Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail:
Fig. 4 is the flow chart of steps of the inventive method.As figure, the inventive method comprises the steps:
After step 402, described set-top box receive the time shift operation of described remote controller, set up unicast tunnel with described video service system and be connected, and carry out the reception of unicast media;
Fig. 1 is a device composition diagram of the present invention; Time shift system comprises as can be seen from Figure 1: remote controller 101, set-top box 102, video service system 103 and display device 104.
Remote controller 101 is provided with time shift control button, can send wireless signal, and set-top box 102 is done the time shift control operation.The time shift operating key is identical with the program request operating key, as be used for positioning control positioning key, increase key, reduce key, determine key, numerical key, the F.F., rewind down, suspending/resuming, a key that are used for broadcasting speed control are to keys such as pushing up, stop.Increase key wherein, reducing key can be by " volume+", " volume-" replaces, and also can adopt other keys to finish this function.Button both can be used word indicating, also can use graphic, or expression simultaneously.Following table is pointed out the diagrammatic representation way of part button.
Functions such as that set-top box 102 can be finished is live, program request can be resolved order and media data from video service system 103 according to the control and video service system 103 communications of remote controller 101.
Video service system 103 can provide the transmission of clean culture and multicast, and program request, live business can be provided according to the requirement of set-top box 102, for the time shift channel, can provide the business of recorded broadcast.Video service system 103 can be made corresponding response according to the request of set-top box 102.To the control request of time shift, can be according to responding accordingly and handle with the agreement interface of set-top box 102.
Display device 104 is responsible for set-top box 102 and is required the video of playing, the demonstration of image.
Control about the time shift channel between video service system 103 and the set-top box 102 is undertaken by the agreement interface.
The agreement interface is summarized as follows:
1) in set-top box one side:
For the broadcast of time shift channel, set-top box needs to set up signaling channel with video service system earlier and is connected, and connects such as RTSP (Real Time Streaming Protocol real-time streaming protocol), and is maintained into the reception end of this time shift channel always.Set-top box is the Media Stream of receiving group again, the broadcast of a programme televised live of beginning.When the user carries out the control operation of time shift, set-top box by the RTSP interface channel to the video service system request of giving an order.When receive that streaming media server sends multicast to the switching notice of clean culture the time, set-top box stops from the multicast channel receiving media data, but receives the media data of clean culture, shifting state when can be described as this moment by the RTSP interface channel.The time shifting state, if proceed the operation of time shift, then continue to carry out the Data Receiving of time shift control and clean culture at the RTSP interface channel.Carry out when what set-top box was received video service system notice that state switchings, VCR parameter modification, timestamp are changed, RTP (Real-time Transport Protocol between clean culture, multicast, be used for the last a kind of host-host protocol of Internet at multimedia data stream) when the bag sequence number changes, make corresponding processing.
2) in video service system one side:
Video service system is issued live media data in multicast channel.For the time shift channel, video service system can be recorded, the program request issue.When the RTSP from set-top box connects, tell the essential information of set-top box about this time shift channel, but time shift scope etc.When set-top box request time shift operation, multicast to the switching of clean culture by RTSP connecting channel announcement machine top box, and send corresponding media data.When moving to live time point at that time, or when a key was arranged to the request on top, the state that the announcement machine top box carries out single broadcast to multicast switched, and stops the transmission of unicast media data.Video service system also can send information such as VCR parameter modification, timestamp change, the change of RTP bag sequence number and give set-top box under corresponding situation.
Program request and common live flow process are known procedure, below in the embodiment communication interface that relates to the time shift part between set-top box and the video service system being done detailed description:
Signaling between set-top box and the video service system is used the RTSP agreement, and both sides follow following explanation, uses the received text of RTSP agreement for following NM part:
1, RTSP_PLAY order and response
Set-top box sends the RTSP_PLAY order can have " Range:npt=" field, can not be with yet, when having this field, if streaming media server is accepted, then must begin to send Media Stream from the position of this fields specify, if the streaming media server refusal then must send it back and should represent refusal.When set-top box sends the RTSP_PLAY order and does not have " Range:npt=" field, if streaming media server is accepted, then to represent defaultly to begin to send Media Stream from current location, the current location regulation is as follows:
A) when playing for the first time (first RTSP_PLAY order that this effective RTSP connects) is the original position of program for the request program current location, is the Media Stream position of the current reception of streaming media server for the programme televised live current location.
B) recovering under the halted state to play is the position that stopped at that time, if do not know this position then from the beginning broadcast.
C) skip forward/back is the current location that Media Stream sends under the broadcast state.
D) playing under the fast forwarding and fast rewinding state or continue fast forwarding and fast rewinding is the current location that Media Stream sends.
Streaming media server is for the response of RTSP_PLAY, when acceptance response, no matter whether the RTSP_PLAY order has " Range:npt=" field, all must comprise this field in the response, original position and the end position of representing current broadcast, for live, the end position of this field uses blank, as the form of " Range:npt=0.000-".
2, RTSP_DESCRIBE order and response
Set-top box adopts the DESCRIBE order of standard to initiate connection request to streaming media server, and streaming media server is responded, and when for request program, must have " a=range:npt=" field in the message entity, the starting and ending position of sign program; When being programme televised live, must not have " a=range:npt=" field in the message entity, identifying current is programme televised live, set-top box is maskable location, skip forward/back/operations such as time-out in view of the above.
3, the regulation of RTSP 455 responses
When streaming media server is not supported (receiving command fast forward as under the live state) for set-top box the current command, need send it back and answer the announcement machine top box, do not support this order under the expression current state.
4, the multicast interface of RTSP
Can use the multicast interface of the signaling realization ISMA MP4 of RTSP, basic procedure is equal to the program request interface, just adopts certain information to identify current multicast interface in the DESCRIBE of streaming media server responds,
Set-top box can be set up multicast channel voluntarily and receive, and can adopt field to represent the current multicast time-moving television that is in DESCRIBE responds.When comprising a multicast address in the streaming media server DESCRIBE reply field, just represent that it is that a multicast connects that current RTSP connects, multicast address is notified in this field.
Time-moving television is exactly the function that adds program request (time shift) on live basis, makes the live content of having been recorded can realize VCR (time-out/skip forward/back/recovery etc.) operation.Live realization is divided into clean culture and multicast dual mode, wherein mode of unicast and program request flow process basically identical, just do not support the VCR operation, for common live multicast mode, there is not signalling path, directly add multicast group and get final product the receiving group code stream, but for time-moving television, need keep a signalling path, be used to transmit the time shift signaling, need to keep a media channel simultaneously and be used to transmit time shift code stream.For simply, the unified regulation of present embodiment is as follows:
1, the flow process of time-moving television and signaling interface adopt the flow process and the signaling interface of RTSP program request, only on the concrete field of message, distinguished, see below continuous the description, if not otherwise specified, the corresponding command interface and the message field of time-moving television are same as the program request interface fully.
2, the transmission of RTSP signaling (TCP) passage is walked in the time shift part of media unification of time-moving television, no matter live part is multicast or UDP clean culture or TCP clean culture.
Fig. 2 is a time shift state transition graph of the present invention; The implementation and the handoff procedure of time-moving television are as follows:
1, (Uniform Resoure Locator: definition uniform resource locator): the URL of time shift and program request implementation are identical for the URL of time shift program
2, the sign of time shift channel.The playing request of time shift channel, URL and play-on-demand program are in full accord, set-top box can judge that to receiveing the response of DESCRIBE current program is live or program request (seeing 1.2) by streaming media server, for programme televised live, the DESCRIBE field of receiveing the response represents that this is a time shift channel.
For the time shift channel, when display shows its channel, on channel displayed number, do special marking: such as having added one " * " number, to be different from common direct broadcast band.The channel type that indicated is as " 12* ", and common frequency channel number is " 13 ".
3, the switching of time shift.
A) when set-top box is in fast-forward mode and be fast-forward to the tail place (catching up with live) of current recorded broadcast, should switch to the normal play of live channel this moment, streaming media server should the announcement machine top box switches to live media channel and receives, adopt the SET_PARAMETER order expansion of RTSP to realize this function, by order the announcement machine top box to switch to live at SET_PARAMETER still is recorded broadcast, and playback rate.
B) when set-top box is in backward mode and fall back on the head place of current recorded broadcast soon, should switch to the normal play of recorded broadcast content this moment, streaming media server should switch to the normal play state by the announcement machine top box, adopt the SET_PARAMETER order expansion of RTSP to realize this function, by switching to live still recorded broadcast and current playback rate at SET_PARAMETER order announcement machine top box.
C) set-top box at any time all can be followed two above-mentioned streaming media server control commands and switches, but for time-moving television, need follow certain user logic and guarantee to switch the use habit that meets the user, the detailed description of switching about time shift illustrates as follows.
When time shift is switched:
A. if whether rewind down allows rewind down, judge according to actual conditions by server, if do not allow then send it back and should cancel, if allow, then directly response can, and in added field, add message such as relevant time stamp, sequence number, the PLAY of standard responds and gets final product.When rewind down to the end the time, send message informing.To be that streaming media server is default play from the recorded broadcast head in the follow-up behavior of this moment.
B. if whether F.F. allows F.F., judge according to actual conditions by server, if do not allow then send it back and should cancel, if allow, then directly response can, and in added field, add message such as relevant time stamp, sequence number.When being fast-forward to current live position, server sends the field notice.The follow-up behavior of this moment is that the server end directly sends live code stream, does not need any response of set-top box.
C. if normal play, whether allow normal play, judge according to actual conditions by server, if do not allow then send it back and to cancel, if allow, then directly response can, and in added field, add message such as relevant time stamp, sequence number, and be the recorded broadcast mode this moment, note, the switching of direct-seeding is determined by server, according to aforementioned interface announcement machine top box.
Whether d. if suspend, allow to suspend, judged according to actual conditions by server, if do not allow then send it back and should cancel, if allow, then directly response can.When entering skip forward/back or normal play mode by time-out, by the RTSP order of standard, necessarily switch to the recorded broadcast code stream this moment, and when switching to skip forward/back or normal mode by time-out, flow process is described referring to appropriate section.
If positioning playing in the time of e., set-top box sends the RTSP PLAY order notice of standard during positioning playing, server responds can, and switch to the recorded broadcast mode, if set-top box navigates to current live position (scroll bar on earth), still by RTSP PLAY order notice server, expression is begun by current location set-top box, and the server response is accepted (also can send refusal) back and switched to live by sending SetParameter.
If f. Shi Yijian is to the top, set-top box is still ordered notice server by RTSP PLAY, and expression is begun by current location, and server responds and can accept to switch to live by sending SetParameter after (also can send 455 refusals).
4, about the response of time in the RTSP PLAY order.The zero-time of the RTSP_PLAY order that sends when set-top box is during greater than maximum time of current recorded broadcast, streaming media server is directly switch to live part and sends the medium code stream, and at first need by SET_PARAMETER announcement machine top box, the zero-time of the RTSP_PLAY order that sends when set-top box is during less than maximum time of current recorded broadcast, according to current time transmission code stream, when the zero-time in the RTSP_PLAY order that set-top box sends is 0, send code stream to set-top box from current recorded broadcast content heads.
The duration of recorded broadcast program is notified.The duration of recorded broadcast program notice adopts when initial the connection and orders the npt field in responding to realize example: Range=npt:2520.000-by first RTSP_PLAY.Represent that recorded broadcast program duration is 2520S.Set-top box utilizes this field to finish the location time shift.
Fig. 3 is a typical time shift control procedure flow chart of the present invention, as shown in the figure, comprising:
Step 301 enters the time shift program live play;
Step 302 is pressed the rewind down key;
Step 304 is pressed fast forward button;
Step 306 judges whether to receive the notice that the streaming media server single broadcast to multicast switches, and is execution in step 307 then, otherwise changes step 305;
Step 307 switches to multicast, withdraws from time shifting broadcasting.
As from the foregoing, the present invention has mainly provided a kind of time shift control method of programme televised live, promptly to programme televised live, can carry out the control method of similar program request.It is simple that the time shift control method that the present invention proposes has realization, objective interface, the characteristics of flexible and convenient operation.Adopt method of the present invention, can realize the time shift control of time shift channel, make the programme televised live playback flexibly of time shift, no longer be can only be passive the program of watching.Method of the present invention realizes simple, objective interface, flexible and convenient operation.The advantage and the competitiveness of IPTV set-top box have been strengthened greatly.
