Referring to fig. 1, which is a functional block diagram of an audio/video playing apparatus 10 according to an embodiment of the present invention, the audio/video playing apparatus 10 may be a common multimedia audio/video playing device (such as, but not limited to, a Digital Light Processing (DLP) projector, a smart lcd tv, etc.) having an audio/video playing function and a playing mode (such as a game mode, a movie mode, etc.) switching function, and may be connected to a network search engine 12 (such as, for example, a google, a yahoo, a Bing, or other network search services) through a network (in a wireless or wired connection manner), as shown in fig. 1, the audio/video playing apparatus 10 includes an audio/video playing device 14, an audio/video Processing device 16, and a network transmission device 18.
The video playback device 14 (e.g., a video projection lens, a liquid crystal display panel, etc.) can be used to play video contents (e.g., electronic games, movies, etc.), and the video processing device 16 can be a microprocessor (e.g., a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), etc.) for performing image-related processing in the video playback device 10 and is electrically connected to the video playback device 14, so as to capture content-related data, such as frame images (e.g., game title images, movie titles, etc.), video content description information (e.g., game types, movie names, etc.), for the video content played by the video playback device 14 for subsequent network searching. The network transmission device 18 can be a network interface card (such as a wireless network card) commonly used for network signal transmission and is electrically connected to the video processing device 16, so that the network transmission device 18 can transmit the web page search result generated by the network search engine 12 according to the content-related data back to the video processing device 16. Therefore, when the audio/video processing device 16 analyzes and compares the web page search result to determine that the classified keyword exists, the audio/video processing device 16 can control the audio/video playing device 14 to execute the playing mode switching operation, so as to adjust the audio/video playing parameter setting of the currently played audio/video content, and thus the audio/video playing device 10 can automatically switch to the audio/video scene mode meeting the current viewing requirement, so as to improve the viewing experience of the user.
Please refer to fig. 1 and fig. 2, fig. 2 is a schematic flow chart of a playback mode switching method according to an embodiment of the present invention, and the playback mode switching method for performing playback mode switching operation by using an audio-visual playback device 10 of the present invention includes the following steps:
step S20: the video/audio playing device 14 plays video/audio content;
step S22: the video processing device 16 retrieves content-related data for video content and uploads the content-related data to the network search engine 12;
step S24: the network search engine 12 returns the web page search result to the video/audio processing device 16 according to the content-related data;
step S26: the video processing device 16 analyzes and compares the web page search result to determine whether there is a classification keyword in the web page search result; if yes, go to step S32; if not, executing step S28;
step S28: the video processing device 16 performs a definition search on the web page search result through the network search engine 12 to generate an advanced web page search result;
step S30: the video/audio processing device 16 analyzes and compares the advanced web page search result to determine whether there is a classification keyword in the advanced web page search result; if yes, go to step S32; if not, executing step S22;
step S32: when determining that the keyword exists, the audio/video processing device 16 controls the audio/video playing device 14 to perform a playing mode switching operation.
The following is a detailed description of the above steps. First, in step S20, the user can control the av playback device 14 to play back the av content to be watched, such as playing a game picture using a projector, playing a movie using a liquid crystal television, and the like. At this time, the av processing device 16 may extract content-related data for the av content and upload the content-related data to the network search engine 12 (step S22), and in more detail, the content-related data may include at least one frame of image in the av content (such as, but not limited to, a first frame of game image, which may also be other frame of game image or a plurality of frame of game images within a certain playing time interval), and the network transmission device 18 uploads the extracted frame of image to the network search engine 12 for image recognition to generate a corresponding web search result (step S24), for example, the extracted game title of image may be uploaded to the google picture search engine, and the google picture search engine may compare and recognize the uploaded game title of image, and send the web search results presented in a high-to-low arrangement manner back to the av processing device 16 via the network transmission device 18.
After receiving the web page search result returned from the network search engine 12, the audio/video processing device 16 may analyze and compare the web page search result to determine whether there is a category keyword in the web page search result (step S26), in more detail, in this embodiment, the audio/video processing device 16 may compare the web page format information (e.g., JSON format program code content) in the web page search result returned from the google image search engine by way of program syntax analysis (parsing) to determine whether there is a category keyword (e.g., game or sport, etc.) that can be used as a basis for switching the play mode. It is to be understood that the program syntax analyzing method can be implemented in other specific embodiments, and the present invention is not limited thereto as long as the same purpose or effect can be achieved.
In the above process, when the audio/video processing device 16 determines that the web page search result contains the classification keyword, the audio/video processing device 16 correspondingly controls the audio/video playing device 14 to execute the playing mode switching operation (step S32), for example, if the web page search result contains the game-related classification keyword (e.g., game), the audio/video processing device 16 switches the current image playing mode of the audio/video playing device 14 to the corresponding audio/video scene mode (i.e., game mode) to control the audio/video playing device 14 to adjust the audio/video playing parameter setting of the audio/video content (e.g., increase the image brightness and contrast, but not limited thereto), so that the audio/video playing apparatus 10 can automatically switch to the audio/video scene mode meeting the current viewing requirement of the user without manual adjustment by the user, thereby effectively improving the viewing experience of the user. In addition, after step S32 is executed, the audio/video playing apparatus 10 is operable to adjust at least one audio/video playing parameter (such as image brightness, contrast, definition, color saturation, etc.) in the adjusted audio/video playing parameter setting, so as to allow a user to perform fine adjustment on the audio/video playing parameter after the audio/video playing apparatus 10 completes the automatic switching operation of the playing mode, so that the audio/video content played by the audio/video playing apparatus 10 can better conform to the viewing preference of the user, thereby generating the viewing experience optimization effect.
It should be noted that the video processing device 16 may further perform a definition search on the web page search result through the network search engine 12 to generate an advanced web page search result and obtain corresponding advanced category keywords, so as to switch the video playback device 14 to a video scene mode more meeting the user's requirements, for example, if the first web page search result is a game name, such as "Sonic at the electrolytic game-Tokyo", the video processing device 16 may upload "at the Sonic game-Tokyo 2020" to the network search engine 12 for a definition search according to the google definition search syntax, and the network search engine 12 may correspondingly transmit the advanced web page search results presented in a high-to-low arrangement manner to the video processing device 16 through the network transmission device 18.
Next, the av processing device 16 can analyze and compare the web page format information (e.g., JSON format program code content) in the advanced web page search result by the above syntax analysis to determine whether there is an advanced classification keyword, such as sports Game (SPG) or First Personal Game (FPG).
In this way, when the audio/video processing device 16 determines that the advanced web page search result includes the advanced classification keyword, the audio/video processing device 16 further controls the audio/video playing device 14 to perform the playing mode switching operation, for example, if the audio/video processing device 16 analyzes that the advanced classification keyword is SPG, the audio/video processing device 16 switches the image playing mode of the audio/video playing device 14 from the game mode to the sports game mode, so as to control the audio/video playing device 14 to perform advanced adjustment (for example, increase the display update frequency or image sharpness, etc.) according to the audio/video playing parameter setting of the audio/video content, thereby further optimizing the viewing experience of the user.
On the other hand, if the av processing device 16 determines that there is no category keyword in the web page search result, the av processing device 16 performs a definition search on the web page search result by the network search engine 12 to generate an advanced web page search result (step S28), for example, the av processing device 16 may upload the web page name of the first web page search result to the network search engine 12 for a definition search according to the google definition search syntax, and the network search engine 12 may transmit the advanced web page search results presented in a high-to-low arrangement with relevance back to the av processing device 16 via the network transmission device 18.
Next, the av processing device 16 can analyze and compare the advanced web page search result to determine whether the advanced web page search result has a classification keyword (step S30). In this step, the audio/video processing device 16 can also compare the web page format information (e.g. JSON format program code content) in the advanced web page search result by means of program syntax analysis to determine whether there is a sort key (e.g. live, sport, video, etc.) that can be used as the basis for switching the playback mode.
In the above process, if the audio/video processing device 16 determines that the advanced web page search result has the classification keyword, the audio/video processing device 16 correspondingly controls the audio/video playing device 14 to perform the playing mode switching operation (step S32), for example, if the advanced web page search result has the classification keyword (e.g., video) related to the video, the audio/video processing device 16 will switch the audio/video scene mode of the current audio/video playing device 14 to the movie mode to control the audio/video playing device 14 to adjust the audio/video playing parameter setting of the audio/video content (e.g., increase the video color saturation and contrast), so that the audio/video playing apparatus 10 can automatically switch to the audio/video scene mode meeting the current viewing requirement of the user without manual adjustment by the user, thereby effectively optimizing the viewing experience of the user.
Otherwise, if the av processing device 16 determines that the classification keyword does not exist in the advanced web page search result, the av processing device 16 will capture other content-related data (e.g. capture a plurality of frame images in another playing time segment) for the av content again and upload the content-related data to the network search engine 12 for searching (step S22), and execute the above-mentioned related steps again until the classification keyword is determined to switch the av playback device 10 to the av scene mode meeting the user' S viewing requirement.
To sum up, compared with the prior art, the invention searches the content-related data of the audio-visual content through the network search engine to obtain the web page search result, and executes the play mode switching operation of the audio-visual play equipment according to the classification keywords obtained after analyzing and comparing the web page search result, so as to achieve the effect that the audio-visual play equipment can automatically switch to the audio-visual scene mode meeting the current viewing requirement of the user without manual adjustment of the user.
It should be noted that the present invention is not limited to the above-mentioned picture searching method, and may also adopt a text searching method instead, in another embodiment, if the content-related data includes content description information (such as game type, movie name, etc.) in the audio-visual content, the audio-visual processing device 16 may upload the retrieved content description information to the google search engine, and the google search engine may perform keyword search on the uploaded content description information, and return the corresponding web page search result to the audio-visual processing device 16 via the network transmission device 18 to serve as a judgment basis for the subsequent playback mode switching operation, and refer to the above-mentioned embodiment for other related descriptions, which will not be described herein again.
In addition, the method for switching the playing mode of the present invention can also be applied to automatically switch the sound effect mode (e.g. theater mode, music mode, etc.), for example, if the web page search result includes the classification keyword (e.g. video) related to the movie, the audio/video processing device 16 will switch the sound effect playing mode of the current audio/video playing device 14 to the theater sound effect scene mode to control the audio/video playing device 14 to adjust the sound effect playing parameters of the audio/video content (e.g. enhance the subwoofer effect), and for other relevant descriptions of the automatic switching operation of the sound effect scene mode, it can refer to the above embodiments to analogize, and thus, it is not described herein again.
The present invention has been described in relation to the above embodiments, which are only examples of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that the invention be covered by the appended claims without departing from the spirit and scope of the invention.
