The opportunity that the multi-screen business is brought is that it makes various communications and entertainment business become more flexible, and better user experience quality (QoE, Quality of Experience) is provided.Fig. 1 shows the sketch map of multi-screen operation system according to exemplary embodiment of the present invention.This new business of multi-screen can support whenever and wherever possible that the user uses various device to visit video frequency program, and it waits for user's PC, TV, mobile hand-held device (like mobile phone, MP3, portable game machine) to bring is that seamless connection and seamless broadcast are experienced.Allow the entertainment selection of user individual customization oneself and promote the user to share happy ability with the family and friends.Such as, adopting the multi-screen technology, the user can accomplish:
● the TV programme of watching the user to subscribe to mobile phone;
● the video of on portable computer, watching video tape recorder to record;
● browse YouTube on TV; Perhaps,
● send to own content of multimedia on friend's the TV with the mobile phone creation.
On the possibility that chance just is to be brought through this multi-screen solution, and not retrained by a kind of single screen or access technology.In brief, be exactly the content of multimedia that available at any time any device access user is collected or subscribe to.In fact; Every kind of screen all has its unique attribute; In consumer mind, every kind of screen also all has its certain location, and the multi-screen video is not that " transplanting " a kind of viewing experience is on the another kind screen; Neither be such as the simple superposition of plurality of devices such as TV, personal computer and portable movable equipment, the multi-screen business also comprise stride kinds of platform such as data warehouse managements such as television services telemanagement, programme content management, ordering informations, reach advertising management alternately.Through this integration, the multi-screen business has been expanded the ability of various screens and has been integrated, and lets each screen give play to its best one side, thereby can enjoy for the user provides a kind of unprecedented perfect video.
There is some evidence that multi-screen will be the next professional main trend in wire/wireless broadband.All members on its industrial chain; Comprise SP of traditional business provider (for example Incumbent and full-service operator) and non-traditional SP (for example Google, Yahoo, Microsoft, Apple etc.); Equipment vendors and content manufacturer all take active action one after another, carry out Product Definition and plan to catch this opportunity.And experience based on the dizzy color multi-screen of true connection, can also cause many new business, for the consumer provides better service, and then brought more business opportunity.
The professional every kind of screen (for example, mobile phone screen, PC screen, TV screen) of multi-screen all has its unique attribute, and in consumer mind, every kind of screen also all has its certain location.The most significantly, the size of every kind of screen is different, and the full HD film of 1080P possibly could fully be showed its full HD resolution on TV, for the mobile phone screen, can send the code stream that adapts with its small screen.In addition, the user is transportable, out of doors, in moving, perhaps can't use the TV screen, therefore possibly switch to mobile phone screen or PC screen.
Especially, as the typical services that many nets merge, the multi-screen business is the network integration and the integrated services emerging service that produces that crosses, and has great vitality and attraction, has also embodied the development main trend of the present integration of three networks.For instance, the multi-screen business can be crossed over three kinds of heterogeneous networks: mobile communications network, internet (can be that the fixed network access also can be the Wi-Fi wireless access), IPTV net.Every kind of network is different to the bandwidth at its terminal.Even if with a kind of network, the user can the actual bandwidth that takies also be different when the spare time, when busy.
Fig. 2 shows the sketch map of multi-screen service access network according to exemplary embodiment of the present invention.Can find out that according to Fig. 2 the professional every kind of terminal (for example television set TV 206, notebook computer 207, mobile phone 208, PC 209 etc.) of multi-screen can be corresponding to access network separately.What for instance, TV 206 (comprising the IPTV STB) was corresponding is IPTV access network 203; What PC 209 was corresponding is Internet access network 205; What mobile phone 208 (comprising other handhold portable equipment) was corresponding is mobile communication access network (for example the 3G mobile communication access network shown in Fig. 3 also can be carried out mobile video class business in Long Term Evolution LTE/4G mobile communications network), or the like.Can carry out recognition of devices according to its access network when in the exemplary embodiment, the user logins.Should be noted that Fig. 2 only carries out exemplary description as the example of multi-screen service access network, in fact, the present invention can be applicable to comprise 4G mobile communications network other communication network of (wherein can not contain radio network controller (RNC) as shown in Figure 2).
According to exemplary embodiment of the present invention, the professional pairing login door in every kind of terminal of multi-screen can be different.What for instance, TV (through the IPTV STB) was corresponding is IPTV portal website; What PC was corresponding is Internet portal website; What mobile phone was corresponding is WAP portal website; Or the like.In exemplary embodiment of the present invention, when logining, the user can (but being not limited to) carry out recognition of devices according to its pairing login door.
According to exemplary embodiment of the present invention, every kind of professional terminal of multi-screen is to set up video to connect employed agreement also can be different.What for instance, TV (through the IPTV STB) used is RTP/RTCP Real-time Transport Control Protocol (RTP/RTCP) agreement; What PC used is the HTTP(Hypertext Transport Protocol) agreement; What mobile phone used is third generation partner program (3GPP) and the special-purpose Streaming Media host-host protocol (for example, packet switching streaming media service PSS) of 3GPP; Or the like.Further, can know from Fig. 2 that the route that the video at every kind of terminal that multi-screen is professional connects also can be different, although they can shared multi-screen business platform.Therefore, according to employed agreement of terminal equipment and/or route, the multi-screen business platform can carry out type identification to the employed equipment of user in fact at any time.
Can find out according to aforementioned content; Because the multi-screen service-user (for example can be crossed over different heterogeneous networks; Cellular mobile communication networks, internet and IPTV network etc.), therefore need a kind of network handover scheme of intelligence to solve the professional screen adjustment of multi-screen.A kind of possible solution is that system's automatic screen adapts to solution, and in this scheme, which kind of equipment what system can automatically discern user's use is, and carries out the adaptability transmission of business tine by its device category.Such as, for the mobile phone screen, send the code stream that adapts with its small screen through mobile communications network.For instance, the multi-screen business platform can adopt the technology of finding out based on device type, and the converting video content is adapted to distinct device automatically.As shown in Figure 2; System can be through such as at least a type that identifies subscriber equipment in the access network of subscriber equipment, login door, employed agreement, the route connection etc.; Then according to the type of subscriber equipment; Automatically carry out the adaptive of subscriber equipment and Internet resources thereof, and can remind the user to carry out the network switching.In addition, system can also provide the differentiated service of different service quality (QoS).Such as, any moment of VIP client, its bandwidth that takies all was constant, but not VIP client can carry out the QoS degradation when Internet resources are nervous.
Yet, in the epoch of stressing personalized service, the needs that the screen of user individual adapts to (such as, certain user needs certain zone on the enlarged and displayed screen) also to satisfy.For instance, the consumer has more individual demand, and meanwhile, every kind of screen has unique attribute (especially screen size), and various screen has different consumer's use habits.Thereby challenge that multi-screen is professional and chance are to allow the consumer to make its amusement personalized.In other words, the multi-screen user should choose any part with scalable whole screen area (frame of video), and on his/her a certain type of multi-screen terminal, plays.For example, when the multi-screen user watched the talk show video content on its mobile phone when, perhaps he only wanted to watch talk show star's face.
Generally speaking, multimedia service needs very big bandwidth.Yet, such as indoor some such places of suburb and depth bad or unsettled cellular mobile communication signal being arranged but, such signal can't be supported in the normal multimedia service on the mobile phone.In this case, in order to ensure the continuity of video content, might the user can be ready to abandon some non-piths of screen area (frame of video), so that reduce bandwidth demand.For example; The multi-screen user watches video on its portable computer; When this user entered into cell edge, he can't obtain enough bandwidth and support this video, in this case; This user can selecting video central portion assign to watch because perhaps bandwidth only enough supports this middle body.Certainly, video player can expand to this middle section full frame, but the definition of this middle section can decrease.
Moreover, when the multi-screen user watches video content on its TV/PC (even under the situation of not watching this video content), might want to record this video content and the video clipping of being recorded is sent to mobile phone via the multi-screen platform.Because the screen of mobile phone is little, this user can be ready to abandon the non-pith (for example, marginal portion) of screen area.For instance, the multi-screen user wants to record 10 minutes talk show video content (only being middle body) and it is stored in his mobile phone, this user even can the video clipping of being recorded be transferred to his friend's mobile phone.
Above about changing or select the demand of screen area in order to satisfy, the invention provides a kind of is multi-screen service selection and/or the solution of recording the part screen area.This is a kind of professional brand-new scheme of multi-screen that is used for, and it has brought many functions and corresponding advantage for the multi-screen user.For instance, therefore scheme of the present invention can satisfy each consumer's individual demand owing to support the multi-screen user to select and/or record the part screen area, and guarantees real-time performance and reduce the bandwidth demand to the support video playback.In addition, the present invention also supports to stride the screen video record.Through adopting scheme of the present invention, can improve multi-screen user's QoE (Quality of experience), this is very favorable under bad or unsettled radio channel condition.
Following indicative flowchart is generally set forth as logical flow chart.Therefore, an embodiment of the step of shown order and the institute's mark method representing to be proposed.Can expect being equivalent to the one or more steps of described method or other step and the method for its part aspect function, the logic OR effect.In addition, form that is adopted and symbol provide for the logic step of explaining this method, and are understood that not limit the scope of this method.Although in flow chart, can adopt the various arrow types and the line style of type, yet they are understood that not limit the scope of corresponding method.In fact, some arrow or other connector possibly only be used to indicate the logic flow of this method.For example, the wait of unspecified duration or supervision phase between the listed step of method shown in arrow can be indicated.In addition, the order that ad hoc approach takes place can in strict accordance with shown in the order of corresponding step, perhaps, can be not in strict accordance with shown in the order of corresponding step.
Fig. 3 has explained the flow chart that is used for the professional method of multi-screen that can realize at the subscriber equipment place according to exemplary embodiment of the present invention.The process of this method can be applicable to hope obtain the professional subscriber equipment/client of multi-screen from network side (such as core net or service provider), and such subscriber equipment/client can include but not limited to mobile phone, personal computer, television set etc.In fact, this method can be regarded as the professional user's active screen adaptation solution of multi-screen.For instance, through using this method, the user can both choose certain piece zone arbitrarily on various terminal screens, can this piece zone be displayed in full screen, and can carry out that this locality is recorded or the backstage is striden screen and recorded to this piece zone video content.This scheme can be given user's initiative, allows the user to select interested screen area according to the wish of oneself, and in real time, dynamically adjusts the size of resolution and code stream.
Can know that according to previous description the multi-screen business can be crossed over different heterogeneous networks usually, for example mobile radio communication, Internet net (can be fixed network insert also can be the Wi-Fi wireless access), IPTV net, or the like.Every kind of network can be different to the bandwidth at its terminal.Even if with a kind of network, the user at the networking when not busy, can the actual bandwidth that takies also can be different when busy.For instance, the bandwidth of mobile communications network is so unstable comparatively speaking, its possibly receive the user position, translational speed, the influence of many factors such as noiseless is arranged.As shown in Figure 2, subscriber equipment (such as television set 206, notebook computer 207, mobile phone 208 and PC 209) can visit multi-screen business platform 201 via corresponding network (such as IPTV Access Network 203, wireless access network, Internet Access Network 205).For instance; For the user who uses mobile phone 208 or PC 209; In fact this user also knows the display effect of unlikely obtaining as IPTV large screen television that kind; Also there is no need to show the whole video pictures on the TV under a lot of in fact situation, display centre area contents or user's interest screen area get final product.In this case, the multi-screen user is just very possible to hope to select interested screen area according to the wish of oneself, so that on undersized mobile phone screen or PC screen, full frame watching carried out in this zone.The user is also very possible to hope to select display resolution according to the wish of oneself with own real-time network condition; Such as; When network condition is good; The demonstration of selection high-resolution in network condition bad (as meeting with congested or interference), selects low resolution to show to guarantee the continuous of video.
According to exemplary embodiment of the present invention; As shown in Figure 3; In step 302, the multi-screen service user device can obtain the video area option that is provided by the multi-screen platform, and said video area option is represented corresponding video area, the different screen zone content with equipment respectively.For instance, through the device screen area dividing being become different piece (for example middle part, upper left quarter, right lower quadrant, full frame, or the like), can various video area option be provided for the multi-screen user.In the exemplary embodiment, said equipment can be one or more different equipment, includes but not limited to mobile phone, portable terminal, personal computer, television set, wireless device etc.Correspondingly; What the video area option that is provided by the multi-screen platform can be directed against is the different screen zone (for example at least a portion screen area) of every kind of equipment in one or more equipment; The user can select the video content of at least a portion screen area thus, so that for example on corresponding apparatus, play.
Fig. 4 shows the sketch map of screen area option according to exemplary embodiment of the present invention.Only show six kinds of video area options [option one: middle part (greatly) although should be noted that Fig. 4; Option 2: upper left quarter (greatly); Option 3: upper right quarter (greatly); Option 4: lower left quarter (greatly); Option 5: right lower quadrant (greatly); Option 6: middle part (little)], but when actual embodiment of the present invention, can wait according to user's needs, channel conditions and/or appointed condition and prepare more or less video area option in advance.For example; Additionally or alternatively; Can be provided for the video content of the first half screen area is amplified (or dwindle or normally) rendering preferences, also can be provided for video content with the left-half screen area and amplify (or dwindle or normally) rendering preferences, or the like.These video area options that offer the multi-screen user can be represented different video area contents.
Consider if use existing message source and channel joint coding method (for example the content source end of multi-screen business platform carries out in real time video coding according to user's selection); Need between user and platform signaling mutual back and forth like this; Especially video coding needs the regular hour, and then real-time can't guarantee.For instance, the content source end executes video coding, indefinite changed (time variation of wireless channel is especially obvious) of network bandwidth conditioning theory again by the time.This also is the reason that existing message source and channel joint coding method never has practicability.In view of this, the present invention has adopted a kind of new scheme.According to this scheme; Can choose some kinds of typical screen selection schemes (six kinds of options that example is as shown in fig. 4 or more or less option) in advance; And encode in advance at the content source end of multi-screen business platform (for the real-time coding that can walk abreast of streaming programme televised live), the user is as long as select on terminal equipment.As shown in Figure 4, outside big square frame can be the screen of full screen display, can be the screen area of choosing in the middle little square frame, and corresponding option is listed in it down.Obviously, under the constant situation of display resolution, if required transmission bandwidth then can significantly be reduced in the zone chosen of transmission only.Adopt such scheme, Signalling exchange very simple (only need upload option gets final product) between user and platform, time delay is very short, because video coding is preprepared or parallel real-time coding, has no the extra scramble time to consume fully.So just guaranteed fully that this kind screen adapts to the operation professional real-time of multi-screen down, and then had the great potential of practicability.
Return with reference to Fig. 3, in step 304, according to multi-screen user's input, subscriber equipment can be at least in part based on being used for the equipment of displaying video area contents, from the option of video area, select corresponding option.According to exemplary embodiment, multi-screen user's input can comprise the selection to the video area option that is provided.For example; The user can adopt the mode of text input to specify selected option; Also can specify selected option according to the templating information that the multi-screen platform is provided; Can also specify selected option through the respective menu content of selecting the multi-screen platform to be provided, even can adopt any combination of aforesaid way to specify selected option.In a further exemplary embodiment; Multi-screen user's input can further include the equipment mark symbol that will be used for playing selected video area content; For example the IP address of the identify label of portable terminal (such as telephone number), personal computer, the number of the account of TV user, or the like.This identifier can be the identifier of the employed current device of multi-screen user, also can be the identifier of miscellaneous equipment.According to exemplary embodiment; The multi-screen user can adopt corresponding pattern of the input or template based on employed device type and/or individual preference at least in part; The link of for example OMA order, SMS order, SIP order or the WAP/Web page; Or the like, so that form the multi-screen user instruction message that will send to the multi-screen platform.
