Description

Digital version school management method and digital version management agency

This request was submitted to the China Liberation Bureau on December 7, 2005.

200510102264.9, "The digital version of the management side of the first of its entire content cited in this book.

Wood field

This relates to the field of digital version school management, especially a digital version management method and digital version management agent for digital content segmentation management.

The background is wooden, and the sharing of information is faster and faster, but the benefits of information sharing are not explained. The problem of sharing digital content is more convenient than ever A age e is a household problem-solving problem.

The current digital version of school management R's idea is Hugh (O, ed ec)

(RO Rgh ec) The content of O is usually dense digital content, that is, the digital content is dense, and RO contains O line decryption, and also describes the allowed use, including d used a certain number of limited times, and so on. The user has to use the digital content, and wait until the appropriate RO can use it. Therefore, the security RO in the unified RO. Usually, O is optional, which is the super score (S e s b o). The following is a description of the existing wooden control plan of R uncontrolled broadcast times.

R is mainly composed of three major functions: the content owner (C Co e ss e) is responsible for the content, and the alumni (gh ss e) is responsible for the RO ’s sub-R agent (R age), which is the device of RM4 in the terminal. The executors of the local DR management strategy reside on each terminal. The end user can use the digital content agent to decrypt the virtual content to the virtual RO, and the user can display the digital content. The use of each content is subject to the restrictions described in R. In order to limit the number of tolerable broadcasts, the element (o) that sets the limit to the number of broadcasts is a natural number, which represents the number of times that O can be broadcasted. The following description exists

<o-ddco 5 </ o-ddco

It means that the RO contains 5 times of O to play the phase. The number of times of each phase of the O-phase is played. If the number of times of broadcasting in the RO has already been played, it will no longer have the number of times of broadcasting.

The modification of the existing wood-based solution is the med-co co element addition e media play e un

co is less than me Co value is not, so co can be me 0 ed-co

The existing solutions mentioned above have the following

(1 because of the non-cause (the terminal is not enough) that the co user is watching, even if it is played because the co has been played, it also reads the user unevenness.

(2) Even in med-co, the visual acuity can not be played once within a fixed time, but e is not very good, not big, and only some operations are effective.

(3) If the user wants to play to see whether the content can be returned to the front, there is no solution for the existing wood.

Content

The purpose of this book is to overcome the problem of providing digital version management methods and digital version management agents to solve the problem of direct broadcast user master positioning broadcast under a certain number of constraints.

To the above purpose, under the wood plan

According to the digital version management method of the present invention, the sub-file segmentation and the sub-file segmentation are described in the sub-file segmentation, and the terminal playback is controlled by the digital version management agent to play the segment-by-segment playback The rooted digital version management agents include digital version management agents, digital version school management agents include media rest file segmentation sheep, and control sheep

The Hugh file segmentation sheep, the Hugh file segmentation attribute at the root, the Hugh segmentation

Control the sheep to control the playback of the files in the segment by segment. For content with a limited number of times, the user is playing digital content. The function is to be arbitrarily played next time to locate the same location as the last time.

Play, in the same broadcast, the user independently fixes the fixed broadcast, and the user has a stronger master in the sight, enhances the user's rest, and the same user can use the complete number of times of the secondary broadcast in the previous broadcast In order to improve the management of the digital version.

Explanation

1 is the hierarchical playback process of the Hugh file provided by this

2 is the main positioning process of users in this book

3 is the sexual flow of the user's main positioning and playback in this fixed 2

4 is a schematic diagram of the unified management of the digital version of this book.

Hugh way

The following is the way to make peace and rest

The current digital version manages the limit of the number of broadcasts during the rest period o), and divides the rest document into several sheep (egme line management is also in

The number of Seme and non-mercury sheep (egme) in the RO is used to support the broadcast function. The maximum limit of the same sheep (eg e) is that they can only be seen in the former sheep (eg e), but not

Previous content.

This plan is off

The first is to increase in RO: the number of sheep (egme) and the size (Segme _Sze), which represent the number of hugh files and the size of sheep, one of which

The segme attribute is an integer. Jiexiu can follow different strategies (eg e's), d mouth can be according to time not] or according to size and other methods.

The most of the files (usually the most files) are completely played-the number of times played.

According to the above method, the rest of the same segment of the file is used in Ro. The following rest

<E E TO-dd: co #PCDATA

The representation of the number of times allows the number of sows to be sowed and the size of the sheep. In other words, the RO includes the number of content broadcasts, and the rest of the file segmentation, where the allowable number of playbacks refers to the number of rests. The above co-rest attributes include the size seg e sze □ sheep seg e s

</ o expemsso> The above example has the same segmentation for regular rest, so seg e is for the same sheep, and the force is divided. The above example shows that the rest file can be played five times and the rest file is divided into 3 and the size is 5.

If the position in a certain sheep is interrupted, the next time you have to make the rules, you must start playing the sheep from the last time or the sheep from the last time.

For example, suppose that the rule requires that the sheep in the previous broadcast start to broadcast, and the last broadcast uses the three broadcast times of the Hugh file in the second paragraph.

Before the broadcast is stopped, the complete broadcast is used to limit the broadcast of one segment of the content. The remaining two complete playbacks are limited to the second segment from the beginning to the playback of the file. .

For each broadcast, R Age will save the information before the update and the number of previous broadcasts, the number of previous broadcasts C e Seg e in the information, and the content of the playback segment, then the number of broadcasts before the update. Play times is the number of times before new play. Information will be kept safely in each

informational .

The Hugh file in the above can also be divided into several parts according to the size of the hierarchical file. The size of the Hugh file can be divided into several, such as the number of files is 1, then divided into 100. According to the subsection, this is no longer.

In addition, according to the proportion of the file, the size is more than 10 sheep. It can be the same or different from the previous method. R Age first rests the size of the file. The sheep size calculated by the ratio can be the same or the size, and the rest are similar.

If R Age is required, the rest size of the file must be described above. The attributes of the number of rest sheep and the size of the rest sheep can only be introduced. The rules for playing in R are as follows <EE TO-ddco co sa -ddco O-dd Segme s><TO-ddco#PCATA>

Or

! E E E TO-ddsegme sze #PC ATA In the user's request co, than the user 5 play co 5. And segme s or segme sze can be played or the size ratio of this value is relatively large. If it is larger, you can egme ze big fish or small fish.

The following refers to step 1 to explain how the purpose of this book.

The first step is the next step of the rest flow shown in this solution. R Age first check the counter co

If it is not greater than 0, then step 6, if co is greater than 0, then step 2. Step 2. Play start position before R Age.

If there is no file error in the last play, the start of the previous play can locate the start of the sheep that was last played.

If there is a complete play before, the file can be played at the beginning. The system can request that the file be played incompletely.

.

Step 3. Play Hugh content. Play seg e update e segme to make it 1.

Step 4: Whether to play, if the file has not been played recently, go to step 3 to download segme and update e seg e, then play step 5.

Step 5. This file is played immediately, and the file is modified by Age to make it 1, ce Seg e, which means the next time The file starts playing.

Step 6 The operation is repeated, that is, the user sees it directly.

For the reason that the user is in the broadcast file, for the next time, the next complete broadcast can still be played from the beginning of the previous seg e. Only the most sheep Seg e can be counted as a complete play to protect the user's.

Secondly, the segmented management of the rest files in this Mingming solves the user-to-play playback, which the user sees in a fixed garden.

If the maximum number of users playing in Yanggu in the previous time is to segme, so the maximum pre-broadcast has a husband, that is, if it is close to the previous segme, then the maximum is almost the size of the segme t, and the result is close to the beginning of segme The maximum is approximately 0.

Therefore, the size of the seg e should be the same. If the seg e is too large, the user broadcasts it. If only segme is introduced, then if the seg e is too small, then the user can fix it too small.

The following combines 2 to explain in detail how the user locates the main (or front) watch

w ed represents the broadcast location the user wants to reach, which is from the beginning of the file to the file a e represents the location of the user's final positioning.

step 1. If the desired playback position of the user is greater than the previous result Wa ed is greater than the seg e, then step 2, otherwise the age is equal to the segme, step 5.

Here, the sheep that are playing before, the sheep are playing, the sheep are playing, the sheep that are playing are also the same as before.

Step 2. RJ Age direct ge (q position) is equal to w e.

Step 3. If the position is greater than this, if yes, go to step 4; otherwise, go to step 5.

Step 4. Modify the value of e segme, step 5

Since the direction of the file may be combined across the previous seg e, so if ge is equal to w ed and greater than this seg e, you need to modify the value of e segme, That is, the position of the sheep before the sheep is the same, save the ce segme. In other words, the final positioning position is the same as the previous upper position.

Step 5. After the above operations are completed, R Age controls the playback and ge playback. In addition, in accordance with the user's playing regulations, which is the starting position of this segment, user-friendly reminders are also provided to enhance user rest. As shown in reference 3, under the rest mode

If the user has used it for the first time, whether the user has more than the number of play times before the birth of the segme, that is, if the co is greater than, if the number of remaining times can only be played, if there are still a few times, can a friendly reminder remind the user to go to the specified The location of this broadcast is about to be broadcast again, and another broadcast will be made. If the user agrees, another broadcast will be made. Relocating to the location specified by the user is a non-self mode. , But only prompts.

Similar to ed-co, the content consumption can also be e. If the content is not e, the content will not disappear.

For limited content broadcasting, users can watch the digital content for reasons, and the next broadcast can be played during the last time, while the simultaneous broadcast can be fixed broadcast, and the user has more control when watching, Enhance the user's rest, the user's, make D more perfect .

This provides the digital version of the management agent. Each includes a digital version of the management agent. 410 The digital version of the management agent. Hugh file segmentation sheep 411 and control sheep 412, Hugh file segmentation sheep 411. Hugh file segmentation properties in the root Hugh file segmentation

The control sheep 412 and the control off broadcast 420 are divided into segments and broadcasted one by one. Hugh Play 420 can be used in the digital version of the management agent shown in 4 or outside.

The control sheep 412 is close to the allowable number of pre-rest days described in Mercury greater than 0. Control the rest to play the pre-broadcast files before the broadcast.

In addition, the control sheep 412 is at the root of the location of the file playback from the user's instruction.

If the target position is less than the previous starting position, the position before the starting position before the starting position will be played or the position will be closed before the sheep is allowed.

If the position is greater than the previous end position, the position before the file will be broadcast, and the position of the sheep will be updated before the position.

The digital version of the management agent 410 can include a broadcast prompt sheep 413 in one step. Then, the control 412 step is such that the destination position is less than the previous starting position, and the broadcast prompt sheep terminal user prompts to wait for receiving the anti-information. Then the position is less than the previous position, before the position of the file, the position playback will receive the anti-information that does not use another playback before the update force of the position sheep, then the previous starting position broadcast

Play Prompt Sheep 413 The uncontrolled sheep communication received by the root, prompting the end user whether to use another play, will receive the counter message from the unterminal Control the sheep.

The above play prompts the sheep 416 Yugen to receive the uncontrolled sheep's notification whether the end user will use another time, and will return the unreceived end user's anti-information to the controlled sheep 413. Play Tips Yang 416 on the digital version of the school management agent 410. Although it is obviously at a better liter, it is not necessary to limit the book. Under the spirit and circumstances of the book, familiar with the field of wood can make changes or changes, but The changes may be based on

Required warranty.
