Family, which can be used, can easily access network, easily enjoy richer media resource and diversified service.
At the same time, the presentation of media resource will be more than simple video, and audio, subtitle, medium type will be more next
It is more rich and varied.Media source is also more than specific content supplier, and more and more producers participate, including very much
Personal user is also offer and the producer of content simultaneously.There is various associations to close for these contents from different suppliers
System, in order to meet the individual demand of different user, these association contents generally require synchronous presentation.In such circumstances, isomery
The inexorable trend that the network integration develops as next generation network has absolutely proved that following communication is no longer certain specific access
Technology, but a variety of access technologies and deposit, cooperate.
In the environment of dissimilar medium network, the media resource that terminal is presented can be transmitted across from multiple transmission channels simultaneously
Come, such as radio network and broadband networks.Presentation for this heterogeneous network terminal has one kind to be based on that information-CI is presented,
The multi-source content distribution mechanisms of Composition Information.CI provides media data using technologies such as HTML5 and XML
Time and spatial information, allow multi-medium data to carry out diversified presentation in terminal.
In the environment of this heterogeneous network, terminal can request related content from server end according to the information in signaling,
But server end, when receive request, related content may have been prepared for, may be not yet.If related content does not have also
It is ready to, the request of terminal just will fail, and then request again, until obtaining related content.This is very big bear to terminal
Load, while also will increase network burden.
Since present some media networks, such as broadband network need to be forwarded content in multiple nodes, therefore deposit
The network delay big even network congestion the problems such as.Therefore receiving end needs that resource content is made requests and cached down in advance
Come, can not be played or the problem of media resource can not be played simultaneously with coping with terminal content.
Therefore, how a new generation dissimilar medium network transmission system in be dynamically added the resource retrievable time, just
As urgent problem to be solved.

Detailed description of the invention
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other feature of the invention,
Objects and advantages will become more apparent upon:
Fig. 1 is the flow chart that client process new in one embodiment of the invention newly sends signaling；
Fig. 2 is the flow chart that client process old in one embodiment of the invention newly sends signaling.
Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection scope.
Nowadays, the diversified webpage user terminal based on heterogeneous network has become the trend of development.It is wide in viewing high quality
While broadcasting video program, people are also higher and higher for the demand of diversified network media services.By multiple types net
In the heterogeneous system of network composition, the time and space layout of client terminal playing media resource is controlled by CI, realizes media resource
Synchronization.In general, there is the delay of very little and fixation by the media resource that broadcast channel comes, therefore for media resource
Synchronous impact it is little；And the contents such as media resource to come from broadband such as audio-video, subtitle, multimedia application are vulnerable to current IP
Network influences, and generates larger and shake delay, brings problem to content synchronization；Meanwhile the content to come from broadband, often
There are problems that effective access period, i.e., it is accessible since some time point, before arriving some time point effectively.Therefore the present invention
The effective time information of content is given, and devises a kind of letter for servicing transmitting terminal and sending the resource correlation available time in advance
The mechanism of order.
In order to solve the problems, such as, first in original signaling or other places are all added newly to every part of media resource content
Attribute: available_begin and available_end, to illustrate that the media resource is ready to and can at server-side
The time of request.
It is embodied as follows
One, takes out a bit as available_time_flag in the reserved field of MPT, is used to refer to current
Server-side whether have sent resource can acquisition time information.
In order to consider existed system compatibility, and in the signaling inform client resource can acquisition time be
It is no it is found that take a bit in the reserved field of MPT as indicating bit, be used to indicate whether current server-side has sent money
Source can acquisition time information.
Reserved field in MPT defines avialable_time_flag, specifically:
Available_time_flag: be used to indicate media resource can acquisition time whether send；If field is set to
0, indicate media resource can acquisition time be not yet ready for, do not send；If field is set to 1, indicate media resource can
Acquisition time information is sent with signaling.
The new definition position in MPT available_time_flag is as follows:
MP table syntax
Two, increase media resource can acquisition time attribute
Newly added attribute available_begin and available_end can be placed on the positions such as signaling, CI, MPU,
Two kinds of specific solutions are given below.
1. increasing descriptor AT descriptor in the signaling can acquisition time for describing media resource
It, can acquisition time for transmit current media asset by increasing a new descriptor AT descriptor
Information.The asset_descriptors { } that AT descriptor is attached to MPT when sending inner is sent together
AT descriptor is defined as follows:
1. introducing
One AT descriptor contains resource and is ready to and retrievable temporal information in sender.If media
Resource can acquisition time it is known that AT descriptor can be contained in MPT.
2. grammer
The syntactic definition of AT descriptor has three ways, such as follows:
One AT descriptor syntax of mode
Mode one defines six attributes, respectively descriptor_tag, descriptor_length in table,
Available_time_count, location_index, available_begin, available_end.In this case
Server-side only sends an AT descriptor, comprising all address sources can acquisition time information.Wherein available_
Time_count indicate be location_type different in MPT it is corresponding have can acquisition time information quantity.
Location_index attribute provide in previous cycle can it be different in MPT corresponding to acquisition time information
The index of location address sources, and by the index by can acquisition time to should be able to obtain resource.
Two AT descriptor syntax of mode
Mode two defines six attributes, respectively descriptor_tag, descriptor_length in table,
Location_count, location_index, available_begin, available_end.In this case server-side
Only send an AT descriptor, comprising all address sources can acquisition time information.Wherein location_count table
What is shown is the quantity in the source location different in MPT.Location_index attribute is provided and can be obtained in previous cycle
The index in its difference source location in MPT corresponding to temporal information, and will be to resource should be able to be obtained by the index
Can acquisition time.If the resource in some source location can acquisition time it is unknown, by available_begin and
Available_end attribute all sets ' 0 '.
Three AT descriptor syntax of mode
Mode three defines five attributes, respectively descriptor_tag, descriptor_length in table,
Location_index, available_begin, available_end.In this case, server-side can send multiple AT
Descriptor, respectively indicate different address source can acquisition time information.Location_index attribute provides currently
In circulation can its difference location address sources in MPT corresponding to acquisition time information index, and pass through index
By can acquisition time to should be able to obtain resource.
3. semantic
The label value of the current descriptor of descriptor_tag-, corresponds to this descriptor, takes herein
Descriptor reserved label value 0x8000；
Descriptor_length-illustrates the length from next field to this descriptor trailer field
MMT_general_ corresponding to the time of the current descriptor description of location_index-expression
Index for address information in location_info.
Available_begin-media resource is earliest can acquisition time.If field all sets 0, show this resource most
Early can acquisition time it is unknown；If field all sets 1, show this resource earliest can acquisition time earlier than current time；
Available_end-media resource the latest can acquisition time.If field all sets 0, show this resource the latest
Can acquisition time it is unknown；If field all sets 1, show that this resource can be just acquired always after being ready to；
Corresponding have can acquisition time information by different location_type in available_time_count-MPT
Quantity；
The quantity in the different sources location in location_count-MPT；
Wherein the usage of available_begin and available_end is as follows:
That is:
(1) if certain resource can be acquired in a period of time, the new attribute that adds distinguishes assignment are as follows:
Available_begin is assigned a value of initial time " UTC1 ", and available_end is assigned a value of the end time
"UTC2"；
(2) it can be acquired always if certain resource starts at a certain moment, newly added attribute distinguishes assignment are as follows:
Available_begin is assigned a value of initial time " UTC1 ", and available_end field all sets 1；
(3) if certain resource can be all acquired at any time, newly added attribute distinguishes assignment are as follows:
Available_begin field all sets 1, available_end field and all sets 1；
(4) if the retrievable situation of certain resource is not known, newly added attribute distinguishes assignment are as follows:
Available_begin field all sets 0, available_end field and all sets 0.
For this scheme, because even without available_time_flag, AT descriptor also can be from
It is identified in descriptor tag, therefore available_time_flag is optional.
2. addition resource can acquisition time information in MMT_general_location_info () descriptor
Increase below addition in the MMT_general_location_info () in MPT can acquisition time method:
MMT_general_location_info () descriptor in MPT provides coming for media resource and related signaling
Source information, wherein location_type be 0x00~0x06 and the value of 0x0C it is corresponding be asset resource location information,
The value of 0x07~0x0B corresponds to the information in signaling source, and 0x0D~0x9F is the field reserved to ISO, and 0xA0~0xFF is
The field reserved to dedicated system.In order to consider the compatibility with former system, select in reserved location_type value
In, use this eight reserved values of 0xA0~0xA7, in the corresponding field of every kind of location_type, described position
The field definition of confidence breath is consistent with 0x00~0x06,0x0C, and in the last addition of each description location information field
Available_begin and available_end attribute.
Increased definition field available_begin and available_end are as follows:
MMT_general_location_info Syntax
Available_begin-media resource is earliest can acquisition time.If field all sets 0, show this resource most
Early can acquisition time it is unknown；If field all sets 1, show this resource earliest can acquisition time earlier than current time；
Available_end-media resource the latest can acquisition time.If field all sets 0, show this resource the latest
Can acquisition time it is unknown；If field all sets 1, show that this resource can be just acquired always after being ready to；
Wherein the usage of available_begin and available_end is as follows:
That is:
(1) if certain resource can be acquired in a period of time, the new attribute that adds distinguishes assignment are as follows:
Available_begin is assigned a value of initial time " UTC1 ", and available_end is assigned a value of the end time
"UTC2"；
(2) it can be acquired always if certain resource starts at a certain moment, newly added attribute distinguishes assignment are as follows:
Available_begin is assigned a value of initial time " UTC1 ", and available_end field all sets 1；
(3) if certain resource can be all acquired at any time, newly added attribute distinguishes assignment are as follows:
Available_begin field all sets 1, available_end field and all sets 1；
(4) if the retrievable situation of certain resource is not known, newly added attribute distinguishes assignment are as follows:
Available_begin field all sets 0, available_end field and all sets 0.
The reserved field being used herein as corresponding to location_type in 0xA0~0xFF, it is possible to use 0x0D~0x9F
In reserved field, the location_type newly defined respectively in 0x00~0x06,0x0C these types location_type's
On the basis of increase can acquisition time information.
Newly added location_type is described as follows:
Value of location_type
