Description

METHOD AND DEVICE FOR PLAYING VIDEO CONTENT
PRIORITY CLAIM AND RELATED APPLICATION
This application claims priority to Chinese Patent Application No. 201310615936.0, entitled "Video Playing Method and Apparatus"filed on November 27, 2013, which is incorporated by reference in its entirety.
TECHNICAL FIELD
The disclosed implementations relate generally to the field of information processing, and in particular, to methods and devices for playing video content on a content page.
BACKGROUND
With the rapid development of computer and network technologies, Internet and instant messaging technologies play a more and more important role in daily life, study and work of people. Furthermore, with the development of mobile Internet technology, the Internet also develops to a mobile trend. Today's society has entered a highly-developed information age, and the enterprise competition has changed from the former single competition mainly depending on products'functions and quality, to competitions of taking the enterprise image, commodities, brands and the like as the important measure and major trend. The change of this trend is inseparable from the rapid development of modern media display and interaction manner.
In the traditional video interaction activities, basic elements such as media owners, media contents, media content receivers, and media presentation reflect the level of civilization of each period to some extent. All the image elements reflect the time trace of the society and economy to different extents as a culture. In some examples for video media promotion, the video media are shown in a manner of a pop-up window at the lower right corner of the webpage. However, the pop-up window is not triggered by the user actively, and many websites propagate fraud information by using a pop-up box at the lower right corner, so that such pop-up method raises a potential internet security concern.
Furthermore, since the video playing has strict requirements on the dimensions of a playing slot on the webpage, the video cannot be played in any arbitrary unoccupied slot on the webpage, and the video playing efficiency is lower. It is therefore desirable to have improved devices and methods for playing media content on various display slots without the limitations of dimensions.

DETAILED DESCRIPTION
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the subject matter presented herein. But it will be apparent to one skilled in the art that the subject matter may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.
The following clearly and completely describes the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
In some embodiments of the present application, the traditional video media content may be played in any display slot regardless of the limitation imposed by the original dimensions of the display slot and the predetermined dimensions of the video media content, so that the efficiency of playing the video media is improved. Video content such as video advertisements can thus enjoy more display opportunities that were not traditionally available to the video content, and thus attract more profit for advertisers and publishers of the display slots alike.
Figure 1 is a block diagram of an advertisement (Ad) environment 100 in accordance with some embodiments. As shown in Figure 1, Ad environment 100 includes device module 102 executed on a terminal device 104, and Ad module 106 executed on an Ad server 108 which is included in a server system 112. Device module 102 communicates with Ad module 106 through one or more networks 110. Ad server 108 also includes an Ad database 114 for storing various Ad media content used in online marketing. For example, Ad module 106 retrieves one or more Ad content from the Ad database 114 upon an Ad request from the terminal device 104, and delivers the Ad content to webpage visitors associated with the terminal device 104. Device module 102 provides various functionalities, such as displaying webpage contents, instant messaging, social networking services, and payment processing, and communications with a server system including Ad server 108. At the server system 112, Ad module 106 of the Ad server 108 provides server-side functionalities associated with Ad services, such as selecting and providing media content (e.g. , video content or image content) related to online marketing (i.e. , Ads) for displaying on the terminal device 104. The environment 100 may include any number of terminal devices like the terminal device 104, each operating independently in its interaction with the server system 112.
As shown in Figure 1, the Ad environment 100 also includes a publisher server 122 communicating with the Ad server 108 through the one or more networks 110. The publisher of content pages controls the content pages containing display slots. For example, a publisher of content pages designs the layout of the content pages including the formatting, locations, and dimensions of the display slots as well as the main content of the content pages. The publisher of content pages stores the content pages at the publisher server 122, such that the content pages may be downloaded by terminal devices. The publisher servers 122 may be a web server providing  webpages to a terminal device based on a URL submitted by the terminal device. When the terminal device 104 downloads a content page from the publisher server 122, the device module 102 (e.g. , a web browser) renders and displays the content page on the terminal device, e.g. , in a browser window. The environment 100 may include any number of publisher servers like the publisher server 122, each operating independently (e.g. , serving different content pages) in its interaction with a given terminal device.
In some embodiments, one or more content request scripts are embedded in a content page downloaded by the terminal device. Each script corresponds a respective display slot that requires dynamic insertion of media content (e.g. , an image Ad or a video Ad) when the content page is rendered at the terminal device 104. In some embodiments, the script generates the request for media content and sends the request to the ad server 108. In some embodiments, the request specifies the media selection criteria imposed by the publisher of the content page. In some embodiments, the request further includes information related to the publisher, the content page, the terminal device, the user of the terminal device, and the display slot to be filled, such that the ad server can select the media content for the display slot based on the selection criteria imposed by the advertiser. For example, when a user browses a webpage using the terminal device 104, the device module 102 executes an ad script for a display slot embedded in the webpage, and the script generates an Ad request and sends it to the Ad server 108 to request for advertising media for the display slot. The Ad request may include one or more information items associated with characteristics of the display slot (Ad slot) , characteristics of the user viewing the content page, the content of the content page, the current time and location, and the requirements on Ads imposed by the publisher of the content page. Upon receipt of the Ad request, the Ad server 108 selects the media content based on the information items contained in the ad request, and sends the selected media content to the terminal device 104 for display. Conventionally, the ad request may include the original dimensions of the display slot, such that the Ad server can select media content that fits well within the original dimensions of the display slot. Thus, conventionally, the ad server only selects video content for a display slot, if the original dimensions of the display slot are substantially equal to the predetermined display dimensions of the video content. As disclosed herein, in some embodiments, the ad request generated by the script does not include dimensions of the display slot； instead, the ad request allows the ad server to select video content for the display slot regardless of the dimensions of the display slot or the dimensions of the video content. Thus, display opportunities for the video content can be increased. As disclosed herein, the script associated with the display slot can be used to generate representative media for the display slot, and adjust the size of the display slot to accommodate the display size of the received video content, such that the  display quality and visual impact of the video content are not diminished by the mismatch between the display slot and the received video content. Other functions of the script are described in other parts of the present disclosure.
In some embodiments, the server system 112 includes one or more processors, database (e.g. , Ad database 114) , an I/O interface (not shown) to one or more terminal devices 104. In some embodiments, server system 112, including the Ad server 108, is implemented on one or more standalone data processing apparatuses or a distributed network of computers. In some embodiments, server system 112 also employs various virtual devices and/or services of third party service providers (e.g. , third-party cloud service providers) to provide the underlying computing resources and/or infrastructure resources of server system 112.
In some embodiments, the publisher server 122 includes one or more processors, databases, an I/O interface (not shown) to one or more terminal devices 104. In some embodiments, the publisher server is implemented on one or more standalone data processing apparatuses or a distributed network of computers. In some embodiments, publisher server 122 also employs various virtual devices and/or services of third party service providers (e.g. , third-party cloud service providers) to provide the underlying computing resources and/or infrastructure resources of publisher server 122.
Examples of terminal device 104 include, but are not limited to, a handheld computer, a wearable computing device, a personal digital assistant (PDA) , a tablet computer, a laptop computer, a desktop computer, a cellular telephone, a smart phone, an enhanced general packet radio service (EGPRS) mobile phone, a media player, a navigation device, a game console, a television, a remote control, or a combination of any two or more of these electronic devices or other electronic devices. 
Examples of one or more networks 110 include local area networks (LAN) and wide area networks (WAN) such as the Internet. One or more networks 110 are, optionally, implemented using any known network protocol, including various wired or wireless protocols, such as Ethernet, Universal Serial Bus (USB) , FIREWIRE, Global System for Mobile Communications (GSM) , Enhanced Data GSM Environment (EDGE) , code division multiple access (CDMA) , time division multiple access (TDMA) , Bluetooth, Wi-Fi, voice over Internet Protocol (VoIP) , Wi-MAX, or any other suitable communication protocol.
Ad environment 100 shown in Figure 1 includes both a terminal device portion (e.g. , device module 102) and a server-side portion (e.g. , Ad module 106) . In some embodiments, data processing is implemented as a standalone application installed on terminal device 104. In addition, the division of functionalities between the terminal device and server portions of client environment data processing can vary in different embodiments.
Figure 2 is a block diagram illustrating a representative terminal device 104 associated with a user in accordance with some embodiments. Terminal device 104, typically, includes one or more processing units (CPUs) 202, one or more network interfaces 204, memory 206, and one or more communication buses 208 for interconnecting these components (sometimes called a chipset) . Client device 104 also includes a user interface 210. User interface 210 includes one or more output devices 212 that enable presentation of media content, including one or more speakers and/or one or more visual displays. User interface 210 also includes one or more input devices 214, including user interface components that facilitate user input such as a keyboard, a mouse, a voice-command input unit or microphone, a touch screen display, a touch-sensitive input pad, a camera, a gesture capturing camera, or other input buttons or controls. Furthermore, some client devices 104 use a microphone and voice recognition or a camera and gesture recognition to supplement or replace the keyboard. Memory 206 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices； and, optionally, includes non-volatile memory, such as one or more magnetic disk storage devices, one or more optical disk storage devices, one or more flash memory devices, or one or more other non-volatile solid state storage devices. Memory 206, optionally, includes one or more storage devices remotely located from one or more processing units 202. Memory 206, or alternatively the non-volatile memory within memory 206, includes a non-transitory computer readable storage medium. In some implementations, memory 206, or the non-transitory computer readable storage medium of memory 206, stores the following programs, modules, and data structures, or a subset or superset thereof:

○user data 244 storing data authored, saved, liked, or chosen as favorites by the user of client device 104 on webpage or in various application platforms.
Each of the above identified elements may be stored in one or more of the previously mentioned memory devices, and corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e. , sets of instructions) need not be implemented as separate software programs, procedures, modules or data structures, and thus various subsets of these modules may be combined or otherwise re-arranged in various implementations. In some implementations, memory 206, optionally, stores a subset of the modules and data structures identified above. Furthermore, memory 206, optionally, stores additional modules and data structures not described above.
In some embodiments, at least some of the functions of client device 104 are performed  by server system 112, and the corresponding sub-modules of these functions may be located within server system 112 rather than client device 104. Ad environment 100 and terminal device 104 shown in Figures 1-2, respectively, are merely illustrative, and different configurations of the modules for implementing the functions described herein are possible in various embodiments.
Figure 3 is a flowchart diagram of a method 300 for playing video content in accordance with some embodiments. As shown in Figure 3, the method starts with a step 301 for acquiring video content. In some embodiments, the video content may be acquired through various manners such as from a local file or a network video stream. The method 300 proceeds to step 302 for showing a first media content in a first slot. The first slot may be at any unoccupied and available slot on a webpage.
In some embodiments, when the dimension of the first slot matches the dimension of the video content, the first content is the video content as acquired, and the video content is played in the first slot. In some embodiments, when the dimension of the video content is played in the first slot, audio component associated with the video content is suppressed.
In some embodiments, when the first slot does not match the video content, the first media content is media content related to the video content and extracted from the video content, and the media content related to the video content is shown in the first slot. In some embodiments, the media content related to the video content may be in forms of text, thumbnail, or audio. In some examples, the thumbnail related to the video content may be generated based on a pixel interpolation algorithm. In some examples, a subtitle file of the video content is acquired. In some examples, a text outline of the video content is generated according to the subtitle file； or an audio outline of the video content is generated according to an audio stream of the video content.
In some embodiments, the method of extracting the media content from to the video content may comprise generating the thumbnail related to the video content based on the pixel interpolation algorithm. In this embodiment, showing the media content related to the video content in the first slot comprises showing the thumbnail in the first slot.
In some embodiments, the method of extracting the media content related to the video content may comprise acquiring the subtitle file of the video content, and generating a text outline of the video content based on the subtitle file. In this embodiment, showing the media content related to the video content in the first slot comprises displaying the text outline in the first slot.
In some embodiments, the method of extracting the media content related to the video content may comprise generating an audio outline of the video content according to the audio stream  of the video content. In this embodiment, showing the media content related to the video content in the first slot comprises showing the audio outline in the first slot.
The method 300 proceeds to step 303 for expanding (303) the first slot to form a second slot based on a triggering command, and playing (303) the video content in the second slot. In some embodiments, when the triggering command is detected in the first slot playing the video content, the first slot is expanded to a second slot with a predetermined dimension for playing the video content in the second slot. In some embodiments, the audio output of the video content is also played while playing the video content in the second slot.
In some embodiments, the triggering command includes a mouse clicking event or a keyboard triggering event from a user in the first slot. When the user triggering command is detected in the first slot playing the video content, the first slot playing the video content is smoothly expanded to the second slot having a predetermined dimension. In some embodiments, a length-width ratio of the predetermined dimension matches with an aspect ratio of the video content. In some embodiments, the audio output of the video content is also played, so that the video may be played with audio output.
In some embodiments while playing the video content in the second slot, when a triggering command is detected in the second slot having the predetermined dimension, the second slot restores to the first slot, and the former video content is played in the restored first slot, and the audio output of the video content is suppressed. In some embodiments, the triggering command may be a mouse clicking event or a keyboard triggering event, from the user in the second slot (with the predetermined dimension) .
In some embodiments, when the user triggering event is detected in the first slot showing the media content related to the video content, the first slot is expanded to the second slot with predetermined dimension, and the video content is played in the second slot.
In some embodiments, when the triggering command is detected in the second slot with the predetermined size, the second slot restores to the first slot, and the media content related to the video content is displayed in the first slot.
In some embodiments, expanding the first slot to the second slot with the predetermined dimension comprises: gradually expanding the width and height of the first slot to the predetermined width and height, and gradually expanding the play bar width of the first slot to the predetermined play bar width, wherein the predetermined dimension is defined by the predetermined width and height.
The first slot may have a predetermined original dimension. It is then determined whether the length-width ratio of the original dimension of the slot matches the aspect ratio of the  video content. If so, the video content is played in the first slot (with the original dimension) ； if not, the generated media content related to the video content is shown in the second slot (with the enlarged dimension) .
In some embodiments, a frame dimension of the video content basically comprises: (1) A full screen: a frame of 4:3, where the whole screen is an effective frame area for projection； (2) a flat widescreen: adding black bars above and below a frame to shield some part of the frame； (3) an anamorphic widescreen: a film in the picture format is most widely employed internationally at present. For the picture format, the film is shot by an anamorphic widescreen lens, and projected also by an anamorphic lens. For example, the standard picture size of the anamorphic widescreen is 16:9.
In some embodiments, when the aspect ratio of the video content is 4:3, and the length-width ratio of the original dimension of the video playing slot is 4:3, then it is determined that the dimension of the video content matches the dimensions of the video playing slot. In some embodiments, when whether the video content matches the video playing slot is determined, some mismatch range, for example 5-15％, may be allowed based on different specific requirements and application environments. It is evident that the present application provides a solution of showing video contents on the webpage in the self smooth expansion manners.
Figures 4A is a schematic diagram illustrating mismatching between a video playing slot 404 and video content 402 on a webpage 400 in accordance with some embodiments. As shown in Figure 4A, in the left figure, a display slot 404 (shown as the broken line box) is longer, and the length-width ratio of the display slot 404 has a greater difference from the aspect ratio (shown as the solid line box) of the playing video content 402, so that the video playing slot 404 does not match the video content 402. In the right figure of Figure 4A on the webpage 405, the display slot 408 (shown as the broken line box) is higher, and the length-width ratio of the display slot 408 has a greater difference from the aspect ratio (shown as the solid line box) of the playing video content 406, so that the video playing slot 408 does not match the video content 406.
Figure 4B are schematic diagrams illustrating matching (scene I) and mismatching (scene II) between a video playing slot and video content in accordance with some embodiments. On the webpage, the first slot is appropriate to play the video, and the first slot has the dimension within an acceptable matching range compared with the dimension of the video content, and may be adapted to play the video content in an adjustment manner (uniform video scaling or tensile deformation) , which is collectively referred to as "ascene I"in the following paragraphs. The scene I is suitable for playing the video directly. On the webpage, the second slot is the area inappropriate to play the video, for example, the dimension of the second slot has a greater difference from the dimension of video content and the dimension is not within an acceptable matching range when  compared with the dimension of the video content, and may not be adapted to playing in the adjustment manner, which is collectively referred to as "a scene II" in the following paragraphs. Images or other files related to the video contents may be displayed first in the scene II.
Figure 5A is a schematic diagram of an expanded video playing slot in accordance with some embodiments. With respect to the scene I, under the condition that the original dimension of the video playing slot matches the video content, video playing comprises two states: playing the normal dimension of the video content, and playing the maximum dimension of the video content.
In the normal dimension, the video is played automatically without audio output. When a mouse is moved by a user into the video scope, the playing slot is smoothly expanded, and the audio output of the video is enabled at the same time. Furthermore, when the video playing slot is changed between the normal size and the maximum size, when it is detected that the mouse is moved outside the scope of the video playing slot, the video playing slot restores back to the original size automatically, and the audio output of the video is suppressed.
When the video playing slot is expanded to the maximum size, an icon with a cross ( “close” icon) 502 button appears in the video playing slot. By clicking the “close” icon 502, and the video playing slot restores back to the normal size by clicking the “close” icon 502. After the video playing slot is expanded to the maximum size, if the mouse is moved outside the video playing area, the video playing area will not be restored automatically. When a user instruction indicating the user wants to load a video with higher definition is received, video content with higher definition is received, loaded, and played. If the user does not want a higher definition video content, the original video is kept.
With respect to the scene II, under the condition that the original dimension of the video playing slot does not match the video content, the media content, such as images or other non-video contents, may be shown in the video playing slot in the original size. In this embodiment, the video playing slot comprises two states: the normal dimension, and maximum dimension.
In the normal dimension (namely the original dimension) , image advertisements or other media files associated with the video content are shown in the video playing slot, where the video content is not played. In this embodiment, when it is detected that the mouse is moved by the user into the video playing slot, the video playing slot may be smoothly expanded. During the resizing of the video playing slot between the normal dimension and the maximum dimension, if the mouse is detected to move outside the scope of the video playing slot, the video playing slot restores automatically.
After the video playing slot is expanded to the maximum dimension, the display of the image advertisements or other media content associated with the video content stops, the video  content starts playing, and the “close” icon 502 appears. The video playing slot may shrink to the normal dimension by clicking the cross icon. At this moment, when the mouse is moved outside the video playing slot with the maximum dimension, the video playing slot will not shrink automatically. In some embodiments, the user request may be further received, and whether the user wants to load video content with higher definition is determined. When it is determined that the user wants video content with a higher definition, video content with higher definition is received, loaded, and played. When it is determined that the user does not want video content with a higher definition, the original video content is kept. After completing the video content, the video content may be replayed or the media content of the video content may be displayed.
Figure 5B are schematic diagrams illustrating a smooth self expansion of a video playing slot in accordance with some embodiments. In some embodiments as shown in Figure 5B, when the video playing slot 512 is in the normal/original dimension, if a mouse-over event is detected, the smooth expansion starts. As shown in Figure 5B, instead of overlaying the context or popping out windows, video playing slot with the original dimension 512 is resized to a dimension 522. The dimension 522 may be a maximum dimension for playing the video content. The dimension 522 may also be the predetermined dimension of the video content as received at the terminal device. During the resizing process from dimension 512 to dimension 522, the playing of video content is not interrupted.
In some embodiments, the expansion process is shown as follows: the width and height of the video slot changes from the original dimension 512 to the maximum dimension 522 gradually； and the width of a playing bar is increased to be maximum gradually； when the video slot reaches the maximum dimension 522, the “close” icon 502 appears at the upper right corner of the video content. In some embodiments, various show bar components 504 of Figure 5A appear in the surrounding areas as shown in Figure 5A. The show bar components 504 may appear on any suitable locations, such as on the left side and the right side of, above, below, and any combination of the video playing slot. Various additional media contents, such as an identification, promotion information, contact information, a two-dimension code, and a lottery component related to the video recommendation object, a control related to a social network chain, may be shown in the show bar components 504. The control related to the social network chain may comprise at least one of a triggering control including forwarding to a friend of the user, a control for receiving a friend comment, a control for prompting a friend’s comment, a control for displaying forwarded times.
Figure 6 are schematic diagrams illustrating expansions of a video playing slot in various directions in accordance with some embodiments. As shown in images (1) - (5) of Figure 6, the video playing slot may be smoothly expanded according to different situations, and the ways of  expansion may comprise: (1) expansion rightward, (2) expansion leftward, (3) expansion upward, (4) expansion downward, and (5) expansion around. In some embodiments, the selection of the expansion directions depends on the composition and layout of the content page. For example, if the display slot is located on the left side of the content page, the display slot may use the expansion mode shown in configuration (1) of Figure 6. If the display slot is located in the center of the content page, the display slot may use the expansion mode shown in configuration (5) of Figure 6. In some embodiments, the expansion may be in both directions horizontally, but have different expansion rates in the two directions based on the horizontal location of the display slot. Similarly, in some embodiments, the expansion may be in both directions vertically, and have different expansion rates in the two directions based on the vertical location of the display slot.
Figure 7A-7D illustrate a flowchart diagram of a method 700 for playing video content on a content page in accordance with some embodiments. In some embodiments, method 700 is performed by a terminal device 104 with one or more processors, memory, and a display. For example, in some embodiments, method 700 is performed by terminal device 104 (Figures 1-2) or a component thereof (e.g. , device module 102, Figures 1-2) . In some embodiments, method 700 is governed by instructions that are stored in a non-transitory computer readable storage medium and the instructions are executed by one or more processors of the terminal device. In some embodiments, the instructions are contained in a script downloaded with the content page, and executed by a browser application at the terminal device. Optional operations are indicated by dashed lines (e.g. , boxes with dashed-line borders) .
The terminal device 104 receives (702) video content from a server system (e.g. , Ad server 108, Figure 1) for dynamic insertion into a display slot available on a content page. The content page contains visual content in addition to the display slot as shown in Figure 5B. In some embodiments, the video content includes a video advertisement file or a beginning portion of the video advertisement file. In some embodiments, the video content is received after an advertisement request is sent from the browser on the terminal device 104 to the Ad server 108 in accordance with the Ad script embedded in the source code of the content page. In some examples, the content page is a webpage, or other types of content interface displayed on the terminal device 104. In some embodiments, the Ad request include various information specifying characteristics of the display slot on the content page, such as the characteristic of the user who is viewing the content page using the terminal device, the content of the content page, the current time and location, the requirements on advertisements imposed by the publisher of the content page. After receiving the Ad request, the Ad server 108 selects the video content based on the information contained in the Ad request.
In some embodiments, the display slots on a content page are surrounded by other visual content (e.g. , visual content 514 of Figure 5B) , such as text, images, and/or icons. The video content and the display slots are arranged in accordance with the dimension of the browser window, or in accordance with the layout imposed by the publisher of the content page.
In some embodiments, the display slot is (704) a dynamic advertisement slot. The terminal device 104 transmits (706) an Ad request from the terminal device to the Ad server 108. In some embodiments, the Ad request does not include information relevant to the display dimensions of the display slot on the content page, and thus the selection of the Ad is no longer constrained by the size and aspect ratio of the display slot. Therefore according to some embodiments of the present application, video Ads receive more display opportunities on the content pages containing non-video-sized Ad slots.
In some embodiments, the terminal device 104 compares (708) the predetermined display dimensions of the received video content with the original dimensions of the display slot on the content page. In some embodiments, the predetermined display dimensions of the received video content and the original dimensions of the display slot are compared to determine whether the predetermined display dimensions are equal to the original dimensions of the display slot. In some embodiments, when it is determined that the predetermined display dimensions are not equal to the original dimensions of the display slot, the terminal device determines whether the predetermined dimensions match the original dimensions according to the predetermined matching criteria.
In some embodiments, by comparing the predetermined display dimensions with the original dimensions, it is directly determined whether the predetermined display dimensions are equal to the original dimensions, or the predetermined display dimensions match the original dimensions according to the predetermined matching criteria, or the predetermined display dimensions do not match the original dimensions based on the predetermined matching criteria.
In some embodiments, the predetermined display dimensions of the video content include one or more selected from: number of pixels in the width dimension and the height dimension, and/or an aspect ratio between the width dimension and the height dimension.
By determining whether predetermined display dimensions of the received video content are equal to the original dimensions of the display slot, the browser can decide whether to display the video content (or the first frame of it) without any change in the display dimension of the video or the dimension of the display slot. In some embodiments, if no dimension change is required, (e.g. , it is determined that the predetermined display dimensions are equal to the original dimensions) , the video content can be played directly in the display slot in its original dimension without playing  its audio component. In some embodiments, if a trigger event indicating user interest is detected, the audio component is played with the video content.
In some embodiments, in accordance with a determination that the predetermined display dimensions of the received video content are not equal to the original dimensions of the display slot, the terminal device displays (710) a visual representation of the received video content in the display slot on the content page.
In some embodiments, in accordance with a determined that the predetermined display dimensions of the received video content are not equal to the original dimensions of the display slot, the browser needs to generate or obtain a visual representation of the received video content, such that the visual representation can be displayed in the display slot instead of the video content. The visual representation has a dimension that fit the display slot.
In some embodiments, the display dimensions of the video content is determined to have the same aspect ratio as the display slot, and the video content has sufficient original resolution to fit within the display slot by only adjusting its pixel resolution (i.e. , no change in aspect ratio is needed) . In such an embodiment, the visual representation of the received video content is basically a rescaled video with its audio component silenced.
In some other embodiments, the display slot has a slightly different aspect ratio than the video content (e.g. , within 10-15％) . In such an embodiment, the visual representation is generated by stretching the aspect ratio of the video file to fit the aspect ratio of the display slot, and a change in video resolution may or may not be needed. In some embodiments, the visual representation also has its audio component suppressed or removed.
In accordance with a determination that the predetermined display dimensions of the received first video file match the original dimensions of the display slot in accordance with predetermined matching criteria, the terminal device adjusts (718) the predetermined display dimensions of the received video content to generate an adjusted video content in accordance with the original dimensions of the display slot. In some embodiments, displaying the visual representation of the received video content includes displaying the adjusted video content in the display slot, and the adjusted video content has the original dimensions of the display slot.
In some embodiments, it is determined that the predetermined dimensions of the received video file match the display dimensions of the display area, when a difference between the predetermined dimensions of the received video file and the display dimensions of the display area is within a predetermined threshold. For example, the threshold includes a difference between a parameter of the predetermined dimensions of the received video file and a parameter of the display dimensions of the display area is determined to be less than about 15％. The parameter of the  predetermined dimensions and the parameter of the display dimensions are one or more selected from a width, a height, and an aspect ratio. In some embodiments, displaying the adjusted video content in the display slot includes suppressing (720) an audio component associated with the received video content while playing the adjusted video content.
In some other embodiments, the display slot has a greatly different aspect ratio and dimension from those of the video content, therefore, a simple rescaling, alone or in combination with a minor stretch of the aspect ratio won’t be sufficient. In such an embodiment, the visual representation may take on a more drastically different form than the original video content.
In accordance with a determination that the predetermined display dimensions of the received video content do not match the original dimensions of the display slot, the terminal device 104 extracts (722) one or more media files from the received video content. In some embodiments, displaying the visual representation of the received video content in the display slot includes displaying the one or more extracted media files in the display slot in accordance with the original dimensions of the display slot. In some embodiments, each of the one or more media files is selected from a set consisting of one or more video frames, thumbnail images, and text files extracted from the received video content.
In some embodiments, it is determined that the predetermined dimensions of the received video content do not match the display dimensions of the display slot, when a difference between the predetermined dimensions of the received video content and the original display dimensions of the display slot is beyond the predetermined threshold, for example, the aspect ratios, the height, or the width of the display slot differs greatly from that of the video content. In some embodiments, in addition to displaying the one or more extracted media files in the display slot, the audio component associated with the received video content is also played while displaying the one or more extracted media files in the display slot.
In some embodiments, displaying the one or more extracted media files in the display slot includes one or more selected from: scrolling (724) the one or more media files in the display area along a predetermined direction, and organizing (724) the one or more media files in the display slot in a grid view. In some embodiments, the media files include a sequence of representative video frames extracted from the video content, and the representative video frames are displayed in a sequence scrolling across the long display slot (e.g. , a banner slot) . In some embodiments, each media file includes a short sequence of representative video frames, and the media files are displayed in a grid in a big Ad display slot, and the sequence of video frames may be rotated in each sub-slot of the grid one by one. In some embodiments, the media files are displayed as still images. In some  embodiments, other arrangement of the media files is possible, as long as the display of the one or more media files observe the original dimensions of the display slot.
In some embodiments, the terminal device detects (712) a first trigger event indicating user interest in the displayed visual representation of the received video content. In some embodiments, the first trigger event includes a mouse-over event (or touch event) within the boundaries of the display slot. In some embodiments, a minimum duration of the mouse-over event is required for the trigger event indicating user interest. In some embodiments, a click event on the visual representation is required.
In some embodiments, in response to detecting the first trigger event, the terminal device gradually resizes (714) the display slot on the content page to accommodate the predetermined display dimensions of the received video content. In some embodiments, the gradual resizing of the display slot causes concurrent rearrangement of the visual content around the resized display slot. In some embodiments, the gradual resizing of the display slot includes expanding and/or shrinking gradually in any direction, as shown in Figure 6. In some embodiments, the direction (s) in which the gradual expansion or shrinking takes depends on the layout of the content page. For example, if the display slot is in the central region of the content page, the expansion may be in both the left and right directions, and/or both up and right directions (e.g. , situation (5) of Figure 6) . If the display slot is near the left edge of the content page, the expansion may only be in the right direction (e.g. , situation (1) of Figure 6) . In some embodiments, the expansion in two opposite directions may take on different rates (e.g. , expands faster to the right than to the left if the display slot is located closer to the left edge of the content page) .
In some embodiments, while the expansion of the display slot is in progress, the visual content surrounding the display slot are rearranged concurrently to fit the shape and size of the display slot. For example, the text and images and other ad slots may be reflowed in the content page to accommodate the current size, location, and dimensions of the resizing Ad display slot. The resizing of the display slot differs from a pop-up window being generated and floated over the content page for displaying the video content.
In some embodiments, the terminal device 104 plays (716) the received video content in the resized display slot on the content page. In some embodiments, in response to the trigger event indicating the user interest, the terminal device plays (726) the received video content in the display slot while the display slot is being gradually resized.
In some embodiments, the terminal device plays the received video content as the resizing of the display slot is in progress, such that the transition between the display of the visual representation of the video content and the display of the video content itself is smooth. This works  well when the displayed visual representation is a rescaled or lightly stretched version of the original video content. In some embodiments, some visual extrapolation is inserted during the transition between the display of the visual representation and the display of the original video content. In some embodiments, playing the received video content includes playing an audio component of the received video content. The audio component of the video content is resumed during the transition between the display of the visual representation and the display of the original video content, and before the display slot is fully resized to play the received video content in its original dimensions.
In some embodiments, in response to the trigger event indicating user interest, the terminal device displays (728) one or more bar components (e.g. , show bar components 504 of Figure 5A) in proximity to the resized display slot. In some embodiments, the bar components include various formats of advertisements, for example, the bar components include one or more items selected from product logo, barcode, QR code, lottery, and product commercial image. In some embodiments, the bar components can be used to display one or more secondary Ads that are associated with the video advertisement, where the dimension of the secondary Ads may match well with the dimension of the bar components.
In some embodiments, while the gradual resizing of the display slot is in progress, the terminal device detects (730) a second trigger event indicating cessation of user interest in the displayed video content. In response to detecting the second trigger event, the terminal device restores (730) the display slot to the original dimensions of the display slot.
In some embodiments before the displaying of the received video content is completed, the terminal device detects (732) a second trigger event indicating cessation of user interest in the displayed video content. In response to detecting the second trigger event, the terminal device restores (732) the display slot to the original dimensions of the display slot, and the terminal device retrieves (732) alternative content to replace the received video content for dynamic insertion into the display slot. In some embodiments, the second trigger event includes moving the mouse out of the resized display area. In some embodiments, the second trigger event includes moving the mouse to some other defined region. In some embodiments, the second trigger event includes explicitly closing the display slot by the user by clicking on the “close” icon (e.g. , “close” icon 502 of Figure 5A) .
In some embodiments, in response to the second trigger event, the device may send another request to the server system to retrieve an alternative content. The alternative content is sent from the server system without checking the dimensions of the alternative content. After receiving the alternative content at the device, the dimension of the alternative content is compared with the display dimension of the display slot. When the dimension of the alternative content is not equal to, but matches the display dimension of the display slot, the dimension of the alternative content is  adjusted to match the display dimension of the display slot, and the adjusted alternative content is displayed in the display slot. When the dimension of the alternative content does not match the display dimension of the display slot, a visual representative of the alternative content is extracted from the alternative content and displayed in the display slot. One or more processes for displaying the alternative content may be substantially similar to those with respect to displaying the received video content as discussed in the present application.
In some embodiments, after the display slot is resized to the predetermined display dimensions of the received video content, the terminal device displays (734) an icon on the display slot while playing the received video content in the display slot. For example, the icon is on the upper right corner of the video playing in the display slot as shown in Figure 5B. In response to an instruction from the user by clicking on the icon, the terminal device restores (734) the resized display slot to the original dimensions of the display slot.
In some embodiments, after the first video file is completed with playing, the terminal device performs one or more selected from: replaying (736) the received video content； restoring (736) the display slot to the original dimensions of the display slot, and displaying (736) the visual representation of the received video content in the restored display slot； and restoring (736) the display slot to the original dimensions of the display slot, and displaying (736) a representation of alternative video content for the received video content in the restored display slot.
In some embodiments, an instruction of requesting for video content related to the currently received video content in a higher definition format is detected at the terminal device. In accordance with detecting the request for the higher definition video content, the terminal device requests for the video content in higher definition format from the Ad server； adjusts the display slot according to the dimension of the video content in higher definition if necessary, and plays the video content in the received higher definition format in the adjusted display slot.
