Description
Technical field
The present invention relates to E-book reader, particularly in the technology of shared electronic book among readers.
Background technology
Electric ink is innovating technologies of a kind of display message.Naked eyes it seems electric ink as one bottle of common ink, but have millions of tiny microcapsules to be suspended in the electric ink liquid.Each capsule is the potpourri of dyestuff and pigment chip, and these tiny chips can receive charge effect.Can liken the microcapsules of electric ink to transparent plastic water-ball.Comprise tens tablees tennis in each water polo, what charge in the water polo is pigment water.If see water polo from the top, we can see that many white tablees tennis float on a liquid, so water polo seems to be white in color.See water polo from the bottom, what you only saw is pigment water, so water polo seems black in color.If you are put into a container to several thousand water polo, and through electric field these tablees tennis are moved between the top and bottom of water polo, you just can see that container is changing color.The basic functional principle of Here it is a kind of typical electronic ink.In fact these water polo are microcapsules of 100 microns of diameters.
Electric ink has many advantages, comprises legibility, and flexibility is prone to cheap manufacturing and low-power consumption etc.Compare with other display technique, the reflectivity and the contrast of electric ink are preferable.Seem the China ink on their sensitive papers, people are read and feel well when handling.Under light comprised direct sunlight, other display technique can feel that some is light and be difficult to read, and saw easily and read based on the demonstration of electric ink.

For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
First embodiment of the invention relates to a kind of transmission method of data of shared electronic book among readers.Its environment of applications is following:
N reader; Interconnect with Radio Link, a reader wherein preserving the electronic book data that remains to be shared is called main reader, and other reader is called from reader; This electronic book data is divided into mutual ind L section, and wherein N, L are the integer greater than 1.
Do not rely on mutually and be meant that every segment data all can resolve or show the page wherein independently, the data that need not rely in other section just can resolve or show.
In this embodiment, each page or leaf is divided into one section, even the page or leaf that will show so not from reader, also can obtain showing as early as possible.In some other embodiment of the present invention, other segmentation method can also be arranged, for example, as one section, perhaps every M page is as one section with each chapters and sections, and M is the integer greater than 1.Multipage as one section, possibly obtained higher compressibility when coding, reduce the wireless transmission data amount.
The flow process of first embodiment is as shown in Figure 1.
In step 101, main reader will send to this from reader from platform mode before the current page data that needs to show of reader.
The alleged foreground mode and the key distinction of background mode are that priority is different among the present invention.
Transmission in back way is meant and in master and slave reader, opens a background process (or thread), in background process, transmits.The priority of background process is lower than foreground process; When having incidents such as page turning or interface alternation to take place; By foreground process these incidents are handled; Conflict as upward having with background process in resource (comprising processor resource, wireless bandwidth resource etc.) when foreground process is handled, then background process can be given foreground process with the resource of conflict.
After this get into step 102, receive the data of wanting page displayed from reader after, show this page immediately.For example, the user selects to see a postscript that main reader passes to cover page from reader.Receive the data of cover page from reader after, show this cover page.
After this get into step 103, accomplish the current processing of wanting page displayed from reader after, master and slave reader startup background process.
After this get into step 104, main reader is transferred to remaining data in the e-book from reader through background process.
After this get into step 105, receive the e-book remaining data through background process from reader.For example, behind reader reception and display cover page or leaf, can receive remaining page data page by page since the 1st page.
After this get into step 106, receive data from the reader buffer memory.After this, when the pairing page or leaf of these data is translated in page turning, can directly show these pages or leaves from reader.
In advance electronic book data is divided into mutual ind multistage; Main reader will want a section of display page place to issue from reader with foreground mode from reader earlier; In back way remaining data in the e-book are issued from the reader buffer memory again; Can make from the reader page that needs of explicit user as early as possible, reduce user's stand-by period, promote user's reading experience.
In this embodiment, page displayed has two kinds of patterns on N the reader:
First kind of pattern is the multi-screen reading model; Be that N reader shows N adjacent page in the same e-book; This pattern can make full use of the hardware advantage of a plurality of readers, enlarges effective reading area, particularly double screen and reads (2 readers; One shows recto, and another shows verso) comparatively meet ordinary people's reading habit
Second kind of pattern is the information sharing model, and promptly page displayed is the same page on N reader.This pattern comparatively is fit to many people's meetings or common study.
In a preferred examples of this embodiment, adopt two readers interconnected with Bluetooth technology, i.e. N=2, the screen of reader adopts electronic ink technologies, to save the electric power protection eyes.
In addition, be appreciated that technical scheme of the present invention also is applicable to interconnected between 3 or the more a plurality of reader, each reader can be same model, also can be different model.The screen of reader can adopt electronic ink technologies, also can adopt other technology, as using liquid crystal display.Except that usable bluetooth connects, also can use WLAN (Wireless Local AreaNetwork is called for short " WLAN "), infrared ray, frequency modulation technology such as (Frequency Modulation are called for short " FM ") to connect between each reader.
Second embodiment of the invention relates to a kind of transmission method of data of shared electronic book among readers.Second embodiment has increased the support to redirect on a large scale on the basis of first embodiment.The flow process of second embodiment is as shown in Figure 2.
In step 201, after main reader was received user's jump instruction, to send the page jump instruction from reader, indication jumped to specified page from reader through wireless connections.
After this get into step 202, judge from reader whether specified page has been kept at buffer memory and,, otherwise get into step 203 if then get into step 209.Because through the remainder of this e-book of background mode transmission,, then might also not accomplish the data transmission of specified page if this background transfer is not also accomplished.
In step 203, from reader with specified page not the information buffer memory notify main reader.
Above-mentioned steps 202 and 203 also can merge, and changes by main reader to judge whether specified page have been passed to from reader.If pass, then get into step 209, if do not pass, then get into step 203.
After this get into step 204, master and slave reader suspends the transmission of background mode.
After this get into step 205, the one piece of data that main reader preferentially will comprise this specified page sends this from reader.This transmission is carried out with foreground mode.
After this get into step 206, receive this segment data and be buffered in this locality from reader.
After this get into step 207, show specified page from reader.
After this get into step 208, master and slave reader continues the transmission of background mode, accomplishes the transmission of this e-book remaining data.After this process ends.
In step 209, show specified page from reader.After this process ends.
When reader jumps to not by the specified page of local cache; Suspend background transfer, prioritised transmission contains the data of specified page, transmitted and show specified page after continue background transfer again; Thereby make from the reader page that needs of explicit user as early as possible, reduce user's stand-by period.
In other embodiment of the present invention, also can adopt other processing mode to redirect, for example wait for that background mode has passed to show again behind the one piece of data that comprises specified page etc.
Third embodiment of the invention relates to a kind of transmission method of data of shared electronic book among readers.The storage format of e-book has two types, just can show after a kind of will the parsing, and another kind just need not resolved and can directly be shown.What this embodiment was directed against is last type.Preceding two embodiments can be suitable for these two types.
The 3rd embodiment improves on the basis of second embodiment, and main improvements are:
In step 101 and 205, main reader is resolved passing to from the page of reader earlier, will pass to from reader through the page data of resolving again.
In step 104 and 208, when the platform mode is transmitted afterwards, main reader directly will be transferred to from reader without the electronic book data of resolving.
After step 106 and 108, receive in back way the data of transmission from reader after, also need resolve receiving data.
Currently issue from reader after wanting page displayed to resolve, after reader is received data, can directly show, need not to resolve, thereby further reduced the stand-by period by main reader.And when background transfer, biography be without the data of resolving, power consumption that on the one hand can balanced master and slave reader; Prolong the time of a plurality of readers as an entire system job; On the other hand, since less usually without the data of resolving, so can save the time of data transmission.
In some other embodiment of the present invention, also can adopt the other technologies scheme outside the 3rd embodiment.For example, can be all to resolve by main reader, what pass in the Radio Link all is the data of having resolved.And for example, can all pass without the data of resolving, the current page or leaf that will show no matter whether is all by resolving from reader.Or the like.
Each method embodiment of the present invention all can be realized with modes such as software, hardware, firmwares.No matter the present invention be with software, hardware, or the firmware mode realize; Instruction code can be stored in the storer of computer-accessible of any kind (for example permanent or revisable; Volatibility or non-volatile; Solid-state or non-solid-state, medium fixing or that change or the like).Equally; Storer can for example be programmable logic array (Programmable Array Logic; Abbreviation " PAL "), RAS (Random Access Memory; Abbreviation " RAM "), programmable read only memory (Programmable Read Only Memory is called for short " PROM "), ROM (read-only memory) (Read-Only Memory is called for short " ROM "), Electrically Erasable Read Only Memory (Electrically Erasable Programmable ROM; Abbreviation " EEPROM "), disk, CD, digital versatile disc (Digital Versatile Disc is called for short " DVD ") or the like.
Though through reference some preferred implementation of the present invention; The present invention is illustrated and describes; But those of ordinary skill in the art should be understood that and can do various changes to it in form with on the details, and without departing from the spirit and scope of the present invention.
