Embodiment
The invention provides a kind of method and system arranging television image the ratio of width to height, the picture the ratio of width to height at every turn received arranges instruction, only arranges picture the ratio of width to height of current shown television channel, simplifies the operating process that user arranges television image the ratio of width to height.
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described in detail.
Embodiment one
Fig. 1 is a kind of embodiment of the method one flow chart arranging television image the ratio of width to height of the present invention, and described method comprises:
Step 101: store the display properties table arranged respectively to each television channel, described display properties table stores original picture the ratio of width to height of the television channel corresponding with it.
After TV first time completes television channel search, database arranges a display properties table to each television channel searched respectively.The original picture aspect ratio value corresponding with it is had in the display properties table of each indicated channel.Time initial, identical original picture aspect ratio value is set can to each television channel, different original picture aspect ratio value is set also can to different television channels, specifically arranges according to actual conditions.
Database gives the display properties table set by each television channel independent of one another, then the original picture aspect ratio value of each television channel is also independent of one another, when original picture aspect ratio value in the display properties table of one of them television channel changes, can not the picture aspect ratio value in the display properties table of other television channels be had an impact.
At present, generally, under initial condition, the original picture aspect ratio value arranged to each television channel is 16:9, i.e. original picture aspect ratio value in the display properties table of each television channel is 16:9.Picture aspect ratio value, except 16:9, also comprises 4:3,1.85:1,2.35:1 etc.
Step 102: the picture the ratio of width to height receiving the current shown television channel that user sends arranges instruction.
Suppose that the picture aspect ratio value in the display properties table of each television channel is 16:9, when user is transferred to another television channel from movie channel, the program pictures that described television channel is play is based on word, adopt the picture aspect ratio value of 16:9, word distortion in picture, now, user needs the picture aspect ratio value of current shown television channel to be adjusted to 4:3 from 16:9, user sends picture the ratio of width to height and arranges instruction, carries the required picture aspect ratio value regulated of user in the instruction of described picture the ratio of width to height.
The picture the ratio of width to height of the current shown television channel that described reception user sends arranges instruction two kinds of implementations:
The first implementation, user sends picture the ratio of width to height by remote controller and arranges instruction:
Current shown picture the ratio of width to height that reception user is sent by remote controller arranges instruction.
The second implementation, user sends picture the ratio of width to height by television operation panel and arranges instruction:
Current shown picture the ratio of width to height that reception user sends on television operation panel arranges instruction.
Above-mentioned two kinds of implementations, the first implementation arranges on a remote control to send the selection key that picture the ratio of width to height arranges instruction, and the second implementation is on television operation panel, arrange the selection key sending the instruction of picture the ratio of width to height.In actual product, remote controller and television operation panel all can be provided with the selection key that transmission picture the ratio of width to height arranges instruction, and user can adopt any one to send the mode of picture the ratio of width to height instruction by unrestricted choice.
Step 103: analyze described picture the ratio of width to height and arrange instruction, resolves described picture the ratio of width to height and arranges the new picture aspect ratio value of carrying in instruction.
Receive after picture the ratio of width to height arranges instruction, resolve described picture the ratio of width to height and the new picture aspect ratio value of carrying in instruction is set.Described new picture aspect ratio value gives the picture aspect ratio value set by picture of current shown television channel for user is required.Described new picture aspect ratio value is that user chosen when sending picture the ratio of width to height and arranging instruction, is the picture aspect ratio value that shown picture aspect ratio value current from described television channel is different.If the current shown picture aspect ratio value of described television channel is 16:9, then it is the picture the ratio of width to height being different from 16:9 that picture the ratio of width to height that user sends arranges new picture aspect ratio value entrained in instruction.
Step 104: utilize described new picture aspect ratio value to adjust picture the ratio of width to height of described television channel.
Adjust picture the ratio of width to height of current shown television channel, with the picture of the program of the described television channel of the wide height display of new picture.If the original picture aspect ratio value of described television channel is 16:9, new picture the ratio of width to height is 4:3, and after adjustment, the ratio of width to height of the program pictures of described television channel is 4:3.
Step 105: replace the original picture aspect ratio value in the display properties table of described television channel by described new picture aspect ratio value.
Original picture aspect ratio value in the display properties table of current shown television channel is upgraded, replaces original picture aspect ratio value by new picture aspect ratio value.It can thus be appreciated that, receive after picture the ratio of width to height that user sends arranges instruction, only replace the original picture aspect ratio value in the display properties table of current shown television channel by the new picture aspect ratio value of carrying in described picture the ratio of width to height.Do not affect original picture aspect ratio value in the display properties table of other television channels, the original picture aspect ratio value of other television channels is constant, and when being namely transferred to other television channels, other television channels still show with the original picture the ratio of width to height in its display properties table.And when recalling to current shown television channel again, be new picture aspect ratio value in the display properties table due to current shown television channel, then the picture that the television channel shown by current shows by new picture aspect ratio value.Certainly, if user is still unsatisfied with the picture shown by new picture the ratio of width to height, step 102 can also be returned and send a picture the ratio of width to height again instruction is set, reset picture aspect ratio value.
Illustrate below: suppose that the picture aspect ratio value that each television channel is given tacit consent to is 16:9, current shown television channel---the program pictures that education channel is play is based on word, adopt the picture aspect ratio value of 16:9, word distortion in picture, now, user needs the picture aspect ratio value of education channel to be adjusted to 4:3 from 16:9.The picture the ratio of width to height receiving the current shown television channel that user sends arranges instruction, and the new picture aspect ratio value of resolving user's setting of carrying in the instruction of described picture the ratio of width to height is 4:3.Utilize new picture aspect ratio value for picture the ratio of width to height of 4:3 adjustment education channel.The original picture aspect ratio value 16:9 in the display properties table of education channel is replaced with described new picture aspect ratio value 4:3.User is transferred to other television channels---and during movie channel, because the original picture aspect ratio value in the display properties table of movie channel is still 16:9, movie channel still shows the picture of its TV programme with original picture aspect ratio value 16:9.When user recalls to education channel from movie channel, owing to being new picture the ratio of width to height 4:3 in the display properties table of education channel, then education channel shows the picture of its program with new picture the ratio of width to height 4:3.
As can be seen here, adopt a kind of method that television image the ratio of width to height is set provided by the present invention, the picture the ratio of width to height receiving the current shown television channel that user sends arranges command value, only can change the picture aspect ratio value of current shown indicated channel, can not have an impact to the picture aspect ratio value of other television channels.That is, change the picture aspect ratio value of education channel, the picture aspect ratio value of movie channel can not be affected.
And when adopting in prior art the method arranging television image the ratio of width to height, because picture aspect ratio value is a global value, all television channels all adopt a unique picture aspect ratio value.When user watches education channel, change picture aspect ratio value into 4:3 from 16:9, then, when user is transferred to movie channel, movie channel also adopts the picture aspect ratio value of 4:3 to show the picture of its TV programme.Now, in order to there be better visual effect, user needs picture aspect ratio value to recall to original 16:9 from 4:3.But when user recalls to education channel again, education channel then adopts picture the ratio of width to height of 16:9 to show its TV programme, and user must adjust, bring complicated operation to user.In the present invention, the picture aspect ratio value only changing education channel can be realized, the picture aspect ratio value of movie channel is not had an impact, simplify the operation of user.
