Description

Multimedia video screen refreshing method

Technical Field

The invention relates to a method for refreshing a multimedia video, in particular to a method for refreshing a mobile phone call video.

Background

With the improvement of living standard and the development of media technology, multimedia video is more and more popular in the life of people, and simultaneously becomes more and more important in the life of people. Particularly, with the popularization of mobile phones and the enhancement of mobile phone functions, mobile phones have evolved from a simple communication tool to a multifunctional multimedia electronic portable device. Thereby providing a lot of convenience for the daily life and use of the consumers.

Multimedia devices need a technical solution involving the overlay of image sources when providing media video services to users. The video content displayed on the screen is actually displayed by overlapping multiple layers of images, for example, a television is watched by using a mobile phone, as shown in fig. 1, the video playing of fig. 1 is formed by overlapping two image sources, one is an image Interface (video decoding image) of a playing area, and the other is a Man-Machine Interface (MMI) image except the playing area, wherein the Man-Machine Interface (MMI) image comprises a status bar in the figure, a soft key zone where options are located, and a control area such as playing/pausing, and the two images are overlapped to form the video playing image which is seen by the user and is shown in the figure.

Two important concepts are referred to here, one is PORT and the other is RENDER, the relationship is shown in figure 2,

PORT: the buffer area is used for storing images, and the image data updated in real time is arranged inside the buffer area.

The method comprises the following steps: and the image superimposer superimposes all the PORTs associated to the register to a block according to the attribute information of the PORTs (such as the information of the position (x, y) of the PORT on the screen relative to the upper left corner of the screen, the transparency of the PORT and the like).

DISPLAY: namely, the display is the screen of our mobile phone, and the RENDER displays the superimposed image on the display through the driver.

The principle of image superposition is shown in fig. 3, there are three PORTs, which are PORT a, PORT B and PORT C, respectively, PORT a is on the uppermost layer of the image, PORT B is on the middle layer, and PORT C is on the lowermost layer, and the right image is formed by superposition of registers. In general, ports have five important attributes, represented by the following structure:

wherein,

x: port is at the x coordinate of the cell phone screen.

y: port is at the y coordinate of the cell phone screen.

And (2) width: port is the width of the cell phone screen.

height: port is at the height of the cell phone screen.

level: port hierarchy in Render.

Take a handset developed under the 6717 platform as an example. The 6717 platform is a TD mobile phone development platform of T3G company, the TD mobile phone supports video phones, and in the process of video call, as shown in fig. 5, its screen refreshing mechanism is also that PORT layers are overlapped, MMI belongs to one PORT, the video phone needs to display remote end and local end images, the two images are also two PORTs, the PORT of the remote end image and the PORT of the local end image are refreshing images all the time.

The user needs to press an OPTION button to pop up an OPTION menu, the menu is shown in fig. 4, the user can select various operations in the OPTION menu, such as muting, stopping sending video, stopping sending audio, and the like, when the OPTION menu is popped up, the PORT of the remote image and the PORT of the local image need to be hidden, however, since the PORT of the remote image and the PORT of the local image are refreshing the images all the time, the OPTION menu interface can be shown as a flower screen, in some cases, a technician can solve the problem by deleting the PORT of the remote image and the PORT of the local image first, when the OPTION menu disappears, the PORT of the remote image and the PORT of the local image are created again, but in this way, due to resource limitation, the risk is high, the reliability is low, and unpredictable problems can be caused by frequent doing the operations, such as crash.

Those skilled in the art are working on developing a video screen-swiping method that is safe and compact.

Detailed Description

Embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings in the specification, elements having similar structures or functions will be denoted by the same reference numerals. The drawings are intended to depict only typical embodiments of the invention, and therefore should not be considered as limiting the scope of the invention.

Fig. 6 is a schematic interface diagram of a user conducting a video call in an embodiment of the present invention, and it should be understood that fig. 6 only shows a part of the interface in a video session, so as to describe a video interface structure according to a preferred embodiment of the present invention. The interface may also include information such as the other party's calling number, last call time, etc.

In the present embodiment, the man-machine interface 610(MMI) includes a status bar, a video call party information bar, options, and a hang-up menu. The opposite side video 620 area is set on the left side of the interface and the present side video 630 is set on the right side of the interface. The origin position (0, 0) of the display screen interface is arranged at the upper left corner of the screen, so the position information of the status bar is (0, 0). The position information of the counterpart video interface is (0, 32). The position information of the present video interface is (180 ). The position coordinate information of the lower right corner of the screen is (240, 320).

Thus, the PORT attribute of fig. 6 is analyzed. The other image is PORT1, whose attribute is (0, 32, 180, 200, 0), the own image is PORT2, whose attribute is (180, 180, 60, 32, 0), the MMI is PORT 3, whose attribute is (0, 0, 240, 320, 255), the smaller the value of level, the higher the level of the level in the image, so that PORT1 and PORT2 are at the highest level in the image level, and PORT 3 is at the lowest level in the image level.

FIG. 7 is a logic flow diagram of a user invoking a menu of options in a call interface in accordance with an embodiment of the present invention. At step 710, the user clicks on the "options" menu. In step 720, the attribute of PORT1 is modified to (240, 320, 180, 200, 255). At step 730, the attribute of PORT2 is modified to (240, 320, 60, 32, 255), and at step 740, the attribute of PORT 3 is modified to (0, 0, 240, 320, 0). At step 750, an "options" menu is displayed. Therefore, both the Port1 and the Port2 are placed at the lower right corner, the remote video and the local video cannot appear in the superposed image in the Render, and the remote video and the local video cannot coincide with the video image source, so that refreshing of the MMI is not influenced, and accidental factors such as screen-up and crash are completely avoided.

FIG. 8 is a logic flow diagram of a user returning to a call interface from a menu of options in one embodiment of the present invention. At step 810, the user clicks the "back" menu on the option interface, at step 820, the attribute of PORT1 is modified to (0, 32, 180, 200, 0), at step 830, the attribute of PORT2 is modified to (180, 180, 60, 32, 0), at step 840, the attribute of PORT 3 is modified to (0, 0, 240, 320, 0), so that both PORT1 and PORT2 appear at the previous location and the distant video and the local video reappear.
