Description
The present invention relates to the display packing of electronic program guides (ElectricalProgram Guide EPG) in a kind of digital cable TV system, more specifically, relate in a kind of digital cable TV system and make electronic program guides show the method for more information.
Now, cable television network progressively strides into digitlization, and in the digital cable TV net, the program that transmits on coaxial cable increases exponentially, for helping the user to select to watch that different programs, electronic program guides become indispensable service in the digital television program.Electronic program guides also becomes the highest part of user watched rate.The information that shows in electronic program guides will become the information that the user the most often sees, and for example advertisement of information of therefore playing in electronic program guides will be that information is propagated effective and efficient manner.
Electronic program guides (EPG) generally is made up of two parts as shown in Figure 1, i.e. the programme information of EPG background and foreground demonstration.Wherein, the programme information that the foreground shows is the program stream from cable TV station's downing code flow among Fig. 1, shows various programme contents; The EPG background generally is a piece image, also some literal can be arranged above the image.Background can design in advance and generate and be stored in the set-top box, or is dynamically obtained from code stream by set-top box.During demonstration, the programme information that the foreground shows covers on the background image, synthetic complete electronic program guide web pages.
In the formation of this existing electronic program guides, because the EPG background is the fixing image of a view picture that occupies whole screen, and programme information only occupies the screen of a part as a rule, like this, much can be used for the part of display message on the screen originally, and fail to be utilized fully.
For the shortcoming that the value that solves existing electronic program guides fails to be fully utilized, the present invention proposes a kind of other information of in electronic program guides, inserting, do not influence the method that normal electronic program guides shows simultaneously.
The present invention compares with existing electronic program guides, has following three characteristics:
1, programme information still superposition show that on the EPG background but the EPG background no longer always occupies the piece image of whole screen, also occupy the piece image of part screen.
2, when the EPG background is an entire image, the screen area that is occupied by the content of programme information can not be processed into transparent viewing area, so that show other information therein.
3, when the EPG background only occupies a part of screen, form blank viewing area in the place that does not have the EPG background, can be used for showing other information.
The present invention is achieved by the following technical solutions: the invention provides a kind of method that makes electronic program guides show more information in the digital cable TV system, described electronic program guides is by constituting the programme information superposition on background parts, described programme information transmits to client terminal by the downing code flow of digital cable TV system, utilize not in the zone that partly occupied by described programme information and/or the described background parts can removed zone as information carrier, and after being written into information, show with described programme information superposition on screen.
When described background parts has occupied whole screen, it is after the transparent viewing area that described client terminal calculates in each program pages the zone that can not be removed in programme information part and the background parts outside the occupied zone of part, and the information beyond the electronic program guides content is presented in the described transparent viewing area.
When described background parts has only occupied the part screen, it is after the blank viewing area that described client terminal calculates in each program pages not by programme information part and the occupied zone of all background parts, and the information beyond the electronic program guides content is presented in the described blank viewing area.

Embodiment 1
In the present embodiment, the information of the programme information of electronic program guides and background parts is all from downing code flow.Fig. 2 A represents the page when the preceding electronic program guides of insertion information of present embodiment, and Fig. 2 B represents the page of electronic program guides after insertion information.In the present embodiment, the programme information on foreground is literal such as " channel, program, CCTV-1～CCTV-5 ".And the EPG background comprises word segments such as " radio and television, ESG, ROXUS, BROADCAST " and do not have the background parts of literal, wherein, part with literal has constituted the part of the content of electronic program guides, can not remove part so also can be called.In addition, the background parts that does not have literal can be a kind of color, also can be the pattern that various color combinations becomes.In Fig. 2 A, the EPG background has occupied whole screen, but on screen, except the word segment of programme information and EPG background, also have some vacant places, these vacant zones because being the programme information superposition with the foreground, electronic program guides on background, form, so can be described as transparent viewing area.In the present embodiment, the transparent viewing area of this piece is used for showing some and the incoherent information of electronic program guides content, advertising message etc. for example is to call these in the following text and the incoherent information of electronic program guides content is insertion information.Electronic program guide web pages after the insertion information is shown in Fig. 2 B.
Because size and position from the transparent viewing area that produces behind the programme information of downing code flow and the background word segment superposition, meeting is selected different electronic program guides displaying contents along with the user and is changed, sometimes, normal electronic program guides content also can occupy whole screen.So in the present embodiment, proposed elder generation and calculated the size and the position of a transparent viewing area, utilized this transparent viewing area to show the method for insertion information again at the set-top box display end.Because the displaying contents of electronic program guides is to be synthesized according to user's the input and the data message of electronic program guides by the set-top box display end, set-top box can calculate in each display page not by electronic program guides content occupation space.
In order to make insertion information not have influence on the demonstration of foreground program guide, will insert above-mentioned transparent viewing area with the information that the electronic program guides content has nothing to do, carry out according to following method.
In the method, the information that needs are inserted transmits by downing code flow.When set-top box enters the electronic program guides state, whenever enter a page, set-top box all calculates the size and the shape of current transparent viewing area, and each pixel in the transparent viewing area is alternative with a kind of specific color pixel, (this colored pixels can not be that the pixel in the program guide displaying contents is used).When set-top box is intercepted and captured the information that will insert from code stream, and after parsing image, the display message of program guide is analyzed.When running into specific colored pixels, just use the pixel of the insertion frame of correspondence position to substitute.Image after merging like this is the image in the transparent viewing area of electronic program guides, is the background image of dynamic change.
Insertion information is inserted with a variety of modes in downing code flow, for example use a specific identity position (Packet Identification PID) to transmit insertion information, and this specific identity position can be indicated to the set top box decodes end in BAT (Banquet association table).
The process of display message generally is such in transparent viewing area.After set-top box enters the electronic program guides show state, the displaying contents of every replacing primary electron program guide, set-top box will be calculated the size and the position of the transparent viewing area of a current page, then under pass in the code stream insertion information of seeking.After insertion information was acquired, set-top box calculated the required minimum viewing area size of this insertion information, if the size of desired minimum viewing area less than current transparent viewing area size, set-top box is presented at this section display message in the current transparent viewing area.If the size of desired minimum viewing area is greater than the size of current transparent viewing area, set-top box will be abandoned this section display message, and seek another section display message in code stream, up to finding suitable display message to be presented in the transparent viewing area.
The insertion information of each section electronic program guides can be carried the information of one section link, any one service that is provided in this CATV transmission can be provided in this link, a channel in the TV programme, also internet address, or the video request program that provides on the television network and online shopping or the like.
Link can attach in the front of each section electronic program guides background, and its form can be with the form of the common approval of any front end and set top box decodes end.
For example advertisement is interested in the content in the insertion information as if the user, can import command adapted thereto, and implicit link information can point to the mode that more relevant information is provided.Interested such as the user for the information of selling fast of the automobile in the viewing area first, after having selected this advertisement, link information can notify front end that the video of one section detailed explanation to this this a automobile is put into mobile code stream, the user just can obtain more information about this automobile, link also can be pointed to the shopping center on the wired network, the user to the ad content interested after, can directly buy on the net.
Embodiment 2
In the present embodiment, the information of the part of the programme information of electronic program guides and background is all from downing code flow.Fig. 3 A represents the electronic program guide web pages before present embodiment information is inserted, and Fig. 3 B represents the electronic program guide web pages after the insertion information.In the present embodiment, the formation of electronic program guides is identical substantially with embodiment 1.As different from Example 1, in Fig. 2 A, the EPG background has occupied whole screen, and in Fig. 3 A, the EPG background does not occupy whole screen, but has only occupied the part of screen.Because this part was not both occupied by the programme information of electronic program guides, was not occupied by background parts, so can be called blank viewing area yet.In the present embodiment, utilize the blank viewing area of this piece that insertion information is shown.Insertion information is put into electronic program guides behind the blank viewing area shown in Fig. 3 B.
Owing to blank viewing area can show that content changes along with the user selects different electronic program guidess, so in the present embodiment, proposed elder generation and calculated the size and the position of a blank viewing area, utilized this blank viewing area to show the method for insertion information again at the set-top box display end.Since blank viewing area be in screen with behind the programme information of electronic program guides and the background parts superposition vacant zone, set-top box can calculate in each display page not by programme information and background parts occupation space.
In order to make the information that is inserted into blank viewing area not have influence on the demonstration of foreground program guide, will insert above-mentioned blank viewing area with the information that the electronic program guides content has nothing to do is to carry out according to following method.
In the method, with the information inserted as one group of object of encoding respectively.Wrist-watch shown in Fig. 3 B and price can be used as two objects and encode respectively.When set-top box enters the electronic program guides state, whenever enter a page, all calculate the size and the position of current blank viewing area, the group objects with advertisement parses again, and with the method for certain scene combination, superposition is in blank viewing area.
The insertion of displaying contents can have a variety of forms, for example, can come the transmitting and displaying content with a special-purpose PID, and in BAT this PID be indicated to the set top box decodes end.
The process of display message generally is such in blank viewing area.After set-top box enters the electronic program guides show state, the displaying contents of every replacing primary electron program guide, set-top box will be calculated the size and the position of the blank viewing area of a current page, then under pass in the code stream insertion information of seeking.After insertion information was acquired, set-top box calculated the required minimum viewing area size of this insertion information, if the size of desired minimum viewing area less than current blank viewing area size, set-top box is presented at this section display message in the current blank viewing area.If the size of desired minimum viewing area is greater than the size of current blank viewing area, set-top box will be abandoned this section display message, and seek another section display message in code stream, up to finding suitable display message to be presented in the blank viewing area.
The insertion information of each section electronic program guides can be carried the information of one section link, and any one service that is provided in this CATV transmission can be provided in this link.Identical about the content relevant with embodiment 1 with the information that links.
