Embodiment
In order to make technical scheme of the present invention and advantage clearer, below in conjunction with accompanying drawing, exemplary embodiment of the present invention is described in more detail, obviously, described embodiment is only a part of embodiment of the present invention, instead of all embodiment's is exhaustive.
The invention provides a kind of part that has realized television broadcasting channel for broadcasting a kind of broadcast control method and the system broadcast with whole group of generation; in improving TV station's broadcast system fail safe, can greatly reduce the construction cost of broadcast system, and the free of discontinuities having solved 7 × 24 hours is broadcasted the contradiction that need shut down maintenance with main/slave link.Fig. 1 is the flow chart of steps of the broadcast control method of the embodiment of the present invention.As shown in Figure 1, the concrete steps of the broadcast control method of the embodiment of the present invention are as follows:
Step S101, broadcasts channel to routine and divides into groups, and forms multiple conventional broadcast system groups.Wherein, each conventional broadcast system group comprises several conventional channels that broadcasts, and each conventional channel that broadcasts comprises master control link and standby control link.Preferably, the conventional channel that broadcasts divides into groups according to the similitude of channel broadcast program.As the channel of the news category of often broadcasting news report is divided into one group, the life kind channel that often broadcasts shopping cuisines is divided into one group.Such packet mode is also highly beneficial for sharing of broadcast items, has avoided same program need repeatedly be transferred to the efficiency of reorganizing and outfit that different video server brings, and has improved space utilisation simultaneously.
Step S102, sets up backup broadcast system group.Wherein, backup broadcast system group comprises several backup broadcast channels, and each backup is broadcasted channel and comprised master control link and standby control link.
Complete the grouping multiple conventional broadcast system groups of formation and setting up after backup broadcast system group, in order to step S103, whether program normally broadcasts.If normally broadcasted, execution step S104, is broadcasted by conventional broadcast system group.If there is broadcasting fault in conventional broadcast system group mid band; or the master control link of channel or standby control link are shut down maintenance and are caused program normally not broadcast; execution step S105, replaces conventional broadcast system group mid band to broadcast by backup broadcast system group mid band.
Wherein, when backup broadcast system group mid band replaces conventional broadcast system group mid band to broadcast, can select part generation to broadcast or whole group of generation broadcast.In part generation, is broadcast when the part referring in conventional broadcast system group is conventional to be broadcasted channel and occur broadcasting fault, in backup broadcast system group, choose with conventional broadcast system group in there is broadcasting failed channel equal number backup broadcast channel and replace and broadcasting.When in whole group of generation, is broadcast the part that refers in conventional broadcast system group or whole group of channel and occurs broadcasting fault, in backup broadcast system group, choose with conventional broadcast system group in conventional backup of broadcasting channel equal number broadcast channel and replace and broadcasting.
In addition, conventional master control link and the standby control link of broadcasting in channel, and it is identical with standby control link framework to back up the master control link broadcasting in channel.Master control link comprises that main broadcaster goes out controller and main negater, and standby control link comprises standby controller and the standby negater of broadcasting.Wherein, main broadcaster goes out controller by core wire jumper and the communication of standby broadcast controller, to realize the synchronous of Broadcast Control emergency operation.Main broadcaster goes out controller and is connected with main negater and standby negater, and the standby controller that broadcasts is connected with main negater and standby negater; The standby controller that broadcasts is provided with the general object interface GPI being connected with main negater and triggers card, for finding that at the standby controller that broadcasts main broadcaster goes out controller and occurs when abnormal, by the main negater of GPI command triggers, switching to standby control channel.Above-mentioned master control link and standby control link control mode are mixes active and standby control mode.Adopt the benefit of this control mode to be, as found that when the standby controller that broadcasts main broadcaster goes out controller and occurs when abnormal, can be at once by the main negater of GPI command triggers, switch in standby control channel, the standby like this control link of broadcasting controller and all devices is connected, control that can all controlled plants of seamless pipe, guarantees that program normally broadcasts.And, mix active and standby control mode and use main negater and standby 2 negaters of negater.Wherein, main broadcast video server born by main negater and other control of broadcasting switching device is switched, and the passage control that standby negater is only born standby broadcasting server is switched.Like this, even if main broadcaster goes out controller at the instant failure that sends Play order, only cause the quiet frame of main video server, and standby video server is by standby Broadcast Control work station control, the not impact of acceptor's Broadcast Control work station, can recover rapidly normal broadcast.
For making technical scheme of the present invention be easier to understand, describe below in conjunction with a concrete application scenarios of broadcast control method of the present invention.For example certain large-scale tv platform, its formal channel quantity externally broadcasting is 40.Adopt broadcast control method provided by the invention, can divide by the strategy of one group of every 10 channel, be divided into 4 conventional broadcast system groups.Meanwhile, build the backup broadcast group of 10 channels as the motor-driven unified backup broadcast system group of conventional broadcast system group.Fig. 2 is the schematic diagram of the grouping back mechanism of the embodiment of the present invention.As shown in Figure 2, the broadcast system group of certain large-scale tv platform comprises 4 conventional broadcast system groups and 1 backup broadcast system group, amounts to 50 channels.And the each channel in broadcast system group is built according to mixing active and standby control mode, to realize the link design requirement without single point of bursting in active and standby control link.Be in each broadcast system group, be divided into active and standby two video servers bunch, and the configuration of active and standby video server bunch is identical, mirror back-up.From framework, the framework of five systems is identical.In the time that the planned shutdown of main/slave link some or multiple channels in conventional broadcast system group is safeguarded or occur broadcasting when fault, can carry out part or whole group of channel is emergent for broadcasting in backup broadcast system group.The broadcast control method that the present invention proposes has ensured reliability and the fail safe of broadcast system, has realized the mobility of the 3rd backup broadcast security mechanism.
From construction cost, in certain large-scale tv platform, there are 40 channels to need to broadcast, as built the independent the 3rd standby mode of broadcasting by tradition, need are built to 40 the 3rd backup broadcast systems that broadcast channel, the construction cost of whole system will increase by 50%.And by broadcast control method of the present invention, because 40 channels have only been built 10 the 3rd backup broadcast channels, back up broadcast by motor-driven mode for other broadcasts channel, not only the fail safe of system is guaranteed, and makes the construction cost of whole system reduce by 75% simultaneously.
In addition, the present invention broadcast by part generation or all for the technical scheme of broadcasting, the free of discontinuities having solved 7 × 24 hours is broadcasted the contradiction that need shut down maintenance with main/slave link.In prior art, shut down maintenance when the primary link of channel, when switching standby link and the 3rd standby link simultaneously and broadcasting; now standby link and the 3rd standby link are discrete; as standby link occurs broadcasting fault, standby link and the 3rd standby link cannot be accomplished seamless switching, can produce single point of bursting.And adopt technical scheme provided by the invention; in the time that the primary link in conventional broadcast system group or standby link need to be shut down maintenance; can transfer to the channel in unified backup broadcast system group to replace broadcast by whole this group group; now, the primary link of the channel in backup broadcast system group and standby link substitute primary link and the standby link in conventional broadcast system group completely.Now, even fault is broadcasted in arbitrary appearance in the primary link in backup broadcast system group or standby link, mix active and standby control mode because the present invention adopts, primary link and standby link in backup broadcast system group also can be accomplished seamless switching, normally broadcast.After conventional broadcast system group has been overhauled, again control is returned to this routine broadcast system group and broadcast, be able to good solution thereby make to shut down maintenance with the contradiction between free of discontinuities broadcast in 7 × 24 hours.
Above embodiment is only in order to technical scheme of the present invention to be described, but not is limited.Therefore,, in the situation that not deviating from spirit of the present invention and essence thereof, those skilled in the art can make various changes, replacement and modification.Obviously, but within these changes, replacement and modification all should be covered by the protection range of the claims in the present invention.
