Cheng Tu.In 302, equipment (for example, equipment 10) can send viewing first content item to server (for example, server 20)
Request.Equipment can be connected to server via network (such as network 28), to receive content.Watch asking for first content item
The selection of certain content title can be included by asking.For example, user can select specific movie or television program to come from by equipment
The media interface viewing of display.In some embodiments, user can be by selecting specific channel come request content, specific frequency
Road may or may not be associated with digital value.Due to the characteristic of on-demand content, interface is possible need not be by channel and digital correlation
Connection.For example, channel can be represented by network station name or identifier (for example, PBS).It is in which case it is possible to use each
Kind technology, such as letter or the personalized order based on user profiles, come the channel that sorts.User can also be by selecting specific
The option of preview (such as surfing) content item carrys out request content in classification.For example, classification may include new issue, it is popular, push away
Recommend etc..In another example, the classification of content can include school.For example, interface may include action, comedy, drama,
The schools such as suspense, terror, documentary film, individual production, children, physical culture.For example, user can ask preview action film, with right
The content for being categorized as action movie carries out surfing.In addition, user can select the labeled content item of preview user, it can be wrapped
Include the content item for being for example marked as liking or being added to playlist.
In 304, equipment can receive first content stream corresponding with first content item from server.Server can make
Asked content is provided with for example suitable Flow Technique.Flow Technique can include such as real-time streaming protocol (RTSP), HTTP
The content stream protocol of dynamic self-adapting stream (DASH), HTML 5 or other present or futures on live TV stream (HLS), HTTP or
Technology.As described above, content item mentioned in this article can be classified as on-demand content.Therefore, server can use usual
It is described as the stream protocol of unicast transmission to provide content, and server can use the stream for being described generally as multicast transmission to assist
Discuss to provide the content of other forms, such as live telecast.For example, server (for example, content server) can be to by unique
Individual equipment (such as set top box) the transmission unicast transmission (for example, content item of stream transmission) of address mark.
In 306, equipment can provide first content item, to be output to the display for being operatively coupled to equipment.Example
Such as, equipment can include set top box, and it provides content item as the output on coupled television set.In order to allow user without
The lingeringly additional content item of preview (for example, as further described herein, substantially immediately), equipment can be automatically from service
Device receives additional content stream.
In 308, equipment can receive content stream set from server.The content stream set can include not passed by streaming
The defeated additional content to equipment.The content stream set can send the request of viewing different content item in equipment (for example, user)
It is received by the device before.For example, the request of viewing different content item can include, such as channel changes or the user of the next item down moves
Make.Therefore, the final request of different projects is watched prior to user in advance, receives these additional streams.By in advance prior to such
Ask transmission content, equipment can with buffer content with provide be similar to surfing traditional broadcast television experience.For example, for tradition
Radio and television, analog broadcast signal include the signal for each available channel, and therefore, TV tuner is only in response to user
Change channel and " tuning " into different channel.By contrast, generally only stream transmission is interior for currently checking for on-demand content
Hold the content of item.For example, program request interface generally only buffers the content in sequence or in user in selecting content item.In order at this
Another content item is watched in the interface of sample, user must exit or terminate to check part, then navigate in a menu to select
Another.Once user have selected another, user have to wait for the project loading (such as stream transmission sufficient amount number
According to), then user can start to check content item.With the appearance for the high-definition content for needing sizable bandwidth, this loading
Process is more and more heavier.Therefore, current program request interface is substantially absent from surfing or relatively quick content pre-viewing.As herein
Described, equipment can shift to an earlier date receiving stream set, therefore, the preview of additional content item can be provided from buffered data.
The content stream set received by equipment can be corresponding with the collection of content items of recommendation.If for example, to buffer in 5
Rong Xiang, then can as the equipment receive corresponding to 5 content streams set.Content item can be based on by equipment or can replacing
The recommendation that selection of land is determined by server.In embodiments, recommend can based on user ask and transmitted as a stream
The first content item of equipment.For example, if user watches action movie, can be wrapped in the collection of content items of the recommendation
Include additional action movie.In another example, the recommendation set can include extensive school, with provide a user it is various can
The content of preview.In addition, the collection of content items of the recommendation can include random content, in order to which user chances on content.Push away
Recommending can also the profile information based on user.For example, profile information can check history including user.This may include checking
Preference, the content type liked such as user.For example, can be based on the item previously checked content school and with performer,
Other preferences of director, playwright, screenwriter, producer etc. determine preference.This checks that history can also be included based on explicit information or implicit
Information checks behavior.For example, the grading that explicit information can include user-defined preference or user provides.For example, user
Content can be graded by grading scale (such as 1 to 5), or like/do not like content item.Implicit information can be based on
Such as determine that user checks the time span of specific content item to determine.In another example, if it is determined that user is being known
Change channel during scene that Wei be not terrified, then recommend the interior perhaps scene that can not include similar classification.Profile information may be used also
With the demographic information including user.For example, in the prevalence of other users that feature is learned with similar demographics
Holding item can be included in recommendation set.It should be noted that preference can also be arranged to keep anonymous or not store all by user
Such as check the profile information of history or demographic information etc.
In embodiments, the content stream received can transmit as a stream since predetermined scene.For example, predetermined field
Scape can be associated with indicating the identifier of scene type.These may include being used for the identifier for describing special scenes, such as
Such as act, be dramatic, having mystery, comedy, romance and terror.For example, determine that user has to dynamic if based on profile information
Make the preference of film, then one or more of the adfluxion received is closed stream may begin at the field for being identified as acting fragment
Scape.Therefore, equipment can provide a user the preview for more having information content by starting content item in interesting joining place.When from spy
When determining scene offer content, equipment can provide the option transmitted as a stream since originating preview item purpose.In addition, stream can be with base
Specific content item is previously watched in user, since recovery point.For example, if user previously have viewed the first half of film,
Then film can be since user terminates previously to check the point of part.In another example, content item can include preview
Piece, therefore, user can before certain movie is selected the multiple trailers of preview.
In embodiments, equipment can be by the way that including channel, come organising content, therefore content stream can be with specific channel
It is associated.For example, channel can be by numeric sorting and mark.In another example, channel can not have to numeral to identify, and
It is to be identified with the school of content.For example, interface can include the channel for action movie and another frequency for comedy
Road etc..In the content embodiment associated with channel, the content stream set of reception can be with the same channel phase currently checked
Adjacent channel set is associated.If for example, the content that user is being watched on channel 10, the content stream received can be with
The content of channel 5 to 9 and 11 to 15 is corresponding.
In 310, equipment can buffer received content stream set.Equipment can delay the content stream set received
Memory (such as storage device 15) is flushed to while being provided to show first content item.As described above, interface can
To carry out organising content using channel set.In such embodiment, equipment can buffer adjacent with currently viewing channel
Channel (for example, channel corresponding with first content item).In addition, equipment can buffer multiple content items and using efficient
Buffer technology.Equipment can be based on each associated channel relative to the close of the first channel (such as the channel currently checked)
