Description
Technical field
The present invention relates to a kind of channel method for pushing of communication technical field, specifically is a kind of based on the channels of network TV method for pushing of user channel switching with rating.
Background technology
Web TV is called Broadband TV (IPTV) again, is to utilize broadband network that a kind of business of interactive multimedia service is provided for the user.IPTV is the result that the Internet and traditional tv merge mutually, video flowing is through being broadcast on the IP network behind the compressed encoding efficiently, and the Internet Protocol Television headend by being positioned at the broadband network edge is live telecast, IPTV such as video and individual's video recording serves and sends the user to as required.The user can use the IPTV business by " IP set-top box+TV " or PC dual mode.The main feature of IPTV is its interactivity and real-time.But different with traditional cable TV is that generally, IPTV is professional by sharing a transmission network with data service, digitized audio and video stream media is sent to user's set-top box.In such network, normally hundreds of Kbps is to 100Mbps for user's access rate, and all TV programme can not be broadcast to all users' set-top box simultaneously as cable TV.Therefore, network need be pushed to specific channel user's set-top box selectively according to user's the demand of watching the action of user's switching channels (promptly according to).In case a user requires switching channels by set-top box, set-top box is at first sent solicitation message to the network equipment, the network equipment is received solicitation message, through after a series of authentication processing flow processs, the content of this channel is pushed to user's set-top box by the multicast mode.Therefore, whole channel comprises switching time: the message that the user sends application is delivered to network equipment time, network equipment authentication processing time and the network equipment content is pushed to time of set-top box, and this time is that institute is non-existent in the traditional cable TV rating mode.At present, it is generally acknowledged that this time is 2-3 second, in addition longer.In order to allow the user obtain good rating is experienced, must narrow down to this stand-by period minimum.Existing method is normally improved this problem by the interFrameGap of adjusting buffer size and video coding is set.
Find through retrieval prior art, U.S. Cisco System Co. (Cisco Systems) is at the white paper of in July, 2005 issue: Managing Delay inIP Video Networks Version 1.0, mention normally by the interFrameGap of adjusting buffer size and video coding is set and improve channel switching time that Cisco System Co. reduces time delay by the control that strengthens that multicast group adds, withdraws from etc.But these methods all only hypothesis once push a programs to the user, therefore can only partly shorten time delay, and can't avoid the time delay that causes by network (comprising authentification of user, network control etc.).Greatly influence the acceptance level of user to IPTV because rating is experienced, thereby influence the large scale deployment of IPTV, therefore, channel change delay has become the problem that presses for solution.
Summary of the invention
The objective of the invention is to deficiency, provide a kind of based on the channels of network TV method for pushing of channel switching with rating at the prior art existence.Make it in the IPTV network, reduce the user and send channel change command (clicking remote controller or television set control panel) to watching that the stand-by period between the TV programme of wanting to see (is to explain for simplicity, to claim that below this stand-by period is a channel change delay), thus realize utilizing less expense to make the user obtain rating experience preferably.
The present invention is achieved by the following technical solutions.The user selects whether to push multiple programs by remote controller or set-top box, if user's not enabled pushes multiple programs, then when the channel switching takes place in the user, network is according to the request of the method process user of routine, promptly stop to push current TV programme, begin to push the TV programme of the new request of user, if the user has started the propelling movement multiple programs, then when the channel switching takes place in the user, network switches historical information according to now pushed program situation and user channel, definite needs stop to push and increasing the program of propelling movement, and push program again according to this result.
Below the present invention is further illustrated, step is as follows:
1) user starts shooting, and selects whether enable the propelling movement multiple programs by remote controller or set-top box, and the storage user is last in the set-top box selects.If this does not elect the user, then keep last selection;
2), and it is pushed to the user by the propelling movement control module if the still non-selected propelling movement multiple programs of enabling of user then reads the program that the user shut down and watch before last time; When the channel switching takes place in the user, push control module and stop to push this programs, need push the new channel of selecting of user according to the user;
3) if the user has selected to enable the propelling movement multiple programs, then at first read the user shut down last time before pushed channel list, and these channels are pushed to the user by pushing control module;
When 4) the channel switching takes place in the user, according to user's input (i.e. the new channel of Xuan Zeing), just in pushed channel list and user's history channel switching historical information, calculate new propelling movement channel list by user behavior statistical module and PREDICTIVE CONTROL module, and begin to push new tabulation by pushing control module.If it is overlapping that new propelling movement channel list and the preceding pushed tabulation of channel switching have, then the lap channel does not change, and the audience rating statistical module is upgraded viewership information as required;
When 5) users with channel switches, the pushed program that set-top box recording is new;
6) user makes amendment when pushing option, the user option that set-top box recording is new.
Described audience rating statistical module, the audience ratings of adding up each channel in certain rating zone (for example Shanghai City, the whole nation), the predicted control module of its statistics is used.The audience rating statistical module is the unique functional module of Network TV Station (perhaps operator) overall situation.This module is upgraded the audience ratings of each TV station in real time according to the information of user behavior statistical module report.Here adopt the notion of average audience ratings, watch in special time period that promptly the spectators of a certain column (perhaps a certain channel) account for the ratio of televiewer's sum in the analyzed area.
Described user behavior statistical module, record and statistics unique user history channel change action, the predicted control module of its statistics is used.The user behavior statistical module is the functional module all relevant with each set-top box.When the channel switching took place the user, this module need be upgraded the corresponding statistics with this user.
Described PREDICTIVE CONTROL module, the result according to audience rating statistical module and user behavior statistical module provide makes prediction when the user sends channel change command, and will predict the outcome and submit to the propelling movement control module.
Described propelling movement control module according to predicting the outcome that the PREDICTIVE CONTROL module provides, is pushed to user side with suitable channel.
The inventive method is compared with traditional method that only pushes a programs to the user, and have following characteristics: 1) user can select whether push multiple programs by remote controller or set-top box panel; 2) if the user selects to push multiple programs, network may push multiple programs to the user; 3) set-top box and network switch historical information according to user channel, and decision needs most pushed program, and it is pushed to the user.
Statistical information and program audience rating information that the present invention utilizes user channel to switch, the user channel switching behavior is predicted, under the prerequisite of not changing existing IPTV propelling movement flow process, the present invention can be by being pushed to multiple programs user's set-top box simultaneously, reduce the time delay of user's switching channels effectively, thereby allow the user obtain rating experience preferably.

1) if the user " enables " channel prediction by remote controller or set-top box setting, then when the user sent channel change command, the channel prediction method came into operation;
2) user's channel change command is received and record by set-top box;
3) the user behavior statistical module writes down this switching behavior, and upgrades historical data;
4) user behavior statistical module notice PREDICTIVE CONTROL module starts forecasting process;
5) PREDICTIVE CONTROL module notice pushes control module and sends channel switching information to access network device;
6) network access equipment is pushed to the subscriber computer top box with Media Stream.
(2) centralized implementation method
As shown in Figure 3, user behavior statistical module and PREDICTIVE CONTROL module push on the controlled entity access network device or of linking to each other with access network device and realize.This implementation method helps centralized control, be convenient to management and upgrading, but extensibility is bad.The audience rating statistical module can realize in identical entity, also can realize in different entities, utilizes certain interface and this entity interaction.
1) if the user " enables " channel prediction by remote controller or set-top box setting, the user sends channel change command;
2) user's channel change command is received and record by set-top box;
3) the user behavior statistical module writes down this switching behavior, and upgrades historical data;
4) user behavior statistical module notice audience rating statistical module channel handover event;
5) the audience rating statistical module is upgraded audience ratings;
6) user behavior statistical module notice PREDICTIVE CONTROL module starts forecasting process;
7) PREDICTIVE CONTROL module notice pushes control module and sends channel switching information to access network device;
8) network access equipment is pushed to the subscriber computer top box with Media Stream.
The present invention reduces the time delay of user's switching channels effectively by multiple programs being pushed to simultaneously user's set-top box.
