Generally, the intelligent device can perform local picture display on the image/video data collected by the camera, or form a recorded file for convenient subsequent storage. Specifically, after the camera collects video, a photosensitive component circuit and a control component in the camera encode the video to generate an encoded video stream, and then the encoded video stream is input into the intelligent device through a parallel port or USB connection; the intelligent equipment decodes the coded video stream input by the camera, and the decoded video stream can be subjected to local preview display through application software in the intelligent equipment; meanwhile, the intelligent equipment can also encode the decoded video stream to form a recorded file.

The smart device is biased towards decoding capability and weaker encoding capability than the camera. In the prior art, in order to ensure that the intelligent device can record video, the camera is arranged to output a coded video stream with a lower specification, but the high coding capability of the camera is obviously not fully utilized, and the high decoding capability of the intelligent device is not fully utilized.

In summary, there is a need for an intelligent device and a video recording method for solving the problem that the intelligent device cannot encode and record a high-specification video stream.

For example, the smart device 200 is controlled using an application running on the smart device. The application program, by configuration, can provide various controls to the user in an intuitive User Interface (UI) on a screen associated with the smart device.

In some embodiments, the mobile terminal 300 may install a software application with the smart device 200 to implement connection communication through a network communication protocol for the purpose of one-to-one control operation and data communication. Such as: the mobile terminal 300 and the intelligent device 200 can be used for establishing a control instruction protocol, the remote control keyboard is synchronized to the mobile terminal 300, and the functions of the intelligent device 200 are controlled by controlling the user interface on the mobile terminal 300.

As also shown in fig. 1, the smart device 200 is also in data communication with the server 400 via a variety of communication means. The smart device 200 may be permitted to make communication connections via a Local Area Network (LAN), a Wireless Local Area Network (WLAN), and other networks. The server 400 may provide various content and interactions to the smart device 200. By way of example, the smart device 200 receives software program updates, or accesses a remotely stored digital media library by sending and receiving information, as well as Electronic Program Guide (EPG) interactions. The server 400 may be a cluster, or may be multiple clusters, and may include one or more types of servers.

The smart device 200 may be a television, a camera, a smart box, a network box, a monitoring device, etc. The particular smart device type, size, resolution, etc. are not limited, and those skilled in the art will appreciate that the smart device 200 may be subject to some changes in performance and configuration as desired.

The smart device 200 may additionally provide a smart network television function of a computer support function, including, but not limited to, a network television, a smart television, an Internet Protocol Television (IPTV), etc., in addition to the broadcast receiving television function.

The camera may be mounted on the smart device 200, such as the camera 501 (e.g., a camera carried by the smart device 200 or a camera removably connected to the smart device 200); the smart device 200, such as the camera 502, may also be remotely connected.

Fig. 2 illustrates a smart device for video recording, the smart device including a video interface, a video processor, and a display.

The video interface is used for receiving the coded video stream output by the camera and sending the coded video stream to the video processor;

the video processor is used for decoding the coded video stream output by the camera to form a decoded video stream; transmitting the decoded video stream to a display for local preview display;

A display for playing the decoded video stream formed by the video processor;

and the video processor is also used for encoding the decoded video stream formed by the video processor and packaging the decoded video stream into a recorded video file.

However, for the above scheme, in most cases, the smart device is biased to decoding capability and encoding capability is weaker than the camera. For example, the decoding capability of the camera ISP (image signal processing) supports 4K@30HZH264/H265 at maximum, and the encoding capability supports 4K@30HZH264/H265 at maximum; the decoding capability of the television SOC supports 4K@30HZH264/H265 at maximum, and the encoding capability supports 1080p@30HZH264 at maximum. Wherein 4K and 1080p refer to the resolution of the video image, namely the number of pixels contained in the video image, which is used for representing the definition of the video image, and the higher the resolution is, the higher the definition is; 30HZ and 60HZ refer to the refresh rate of the video, namely the number of times that a screen is refreshed every second of pictures, and are used for representing the fluency of video images, and the higher the refresh rate is, the better the fluency is; h264 and H265 refer to video compression formats, and H265 has lower code rate and higher definition than H264, saves more bandwidth or storage space, and improves efficiency. The above indicators and numbers of codec capability are merely examples, and are not limiting.

It can be seen that the decoding capability of the television is comparable to that of the camera, while the encoding capability is poor. Thus, when the camera inputs a high-specification coded video stream, such as a resolution of 4K, the smart device can decode it without the ability to encode it. Therefore, if the intelligent device is required to record video, the camera needs to output a lower-specification coded video stream, for example, the resolution is 1080p, which obviously does not fully utilize the capability of the camera to output a high-specification coded video stream (the camera has the coding capability of 4K resolution); meanwhile, the method is limited by the coding capability of the intelligent equipment, the intelligent equipment cannot generate video recording files with high specification, the definition, the fluency, the compression format and the like are influenced, and the user experience is greatly reduced; in addition, the intelligent equipment is complicated in coding process, more computing resources of the intelligent equipment can be occupied, and video recording efficiency is reduced.

In addition, in the method, a matching process of the encoding capability of the camera and the decoding capability of the intelligent device is not available. Therefore, under the condition that the intelligent equipment does not configure the coding capability of the camera and the decoding capability of the intelligent equipment, the camera blindly codes according to the set coding format and outputs the coded video stream, and the intelligent equipment does not have the corresponding decoding capability and cannot decode the coded video stream.

In order to solve the problems, the embodiment of the invention provides an intelligent device, which is used for solving the problems that the encoding capability of a camera is wasted, the intelligent device cannot encode and record a high-specification video stream, the video recording efficiency is low, and the intelligent device cannot decode and display the video stream.

In some embodiments, a user may input a user command at a displayed Graphical User Interface (GUI), and the user input interface receives the user input command through the Graphical User Interface (GUI). Alternatively, the user may input the user command by inputting a specific sound or gesture, and the user input interface recognizes the sound or gesture through the sensor to receive the user input command.

In some embodiments, a "user interface" is a media interface for interaction and exchange of information between an application or operating system and a user that enables conversion between an internal form of information and a form acceptable to the user. A commonly used presentation form of the user interface is a graphical user interface (Graphic User Interface, GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It may be an interface element such as an icon, a window, a control, etc. displayed in a display screen of the electronic device, where the control may include a visual interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget, etc.

A main processor for performing some operations in a pre-power-up mode and/or displaying a picture in a normal mode. One or more sub-processors for one operation in a standby mode or the like.

In this embodiment, the controller 210 is configured to encapsulate the first video stream into a recording file when determining that the second encoding capability of the video processor is lower than the first encoding capability based on the video recording instruction.

Based on the hardware configuration block diagram of the smart device 200 shown in fig. 3, the embodiment of the present invention further provides a video recording method, as shown in fig. 4.

Step 401, the intelligent equipment receives a video recording instruction aiming at the currently played video; the current playing video is a second video stream obtained by decoding a first video stream which is encoded by the camera according to the first encoding capability by the intelligent device according to the first decoding capability; the first encoding capability is the highest encoding capability matched with the decoding capability of the intelligent device in the encoding capability of the camera;

step 402, when the second encoding capability of the intelligent device is lower than the first encoding capability, the intelligent device encapsulates the first video stream into a recording file.

For example, the camera supports two encoding capabilities of 4K@30HZH265, 1080p@30HZH265, the television supports two decoding capabilities of 4K@30HZH265, 1080p@30HZH265, and supports two encoding capabilities of 1080p@30HZH264, 720 p@30HZH264, as shown in Table 1. Based on the principle that the coding capacity of the camera is matched with the decoding capacity of the television and is the highest coding capacity of the camera, the first coding capacity of the camera is configured to be 4K@30HZH265, and the first decoding capacity of the television is 4K@30HZH265. The camera outputs a first video stream according to the first coding capability of 4K@30HZH265, the television decodes the first video stream according to the first decoding capability of 4K@30HZH265 to obtain a second video stream with the format of 4K@30HZ, and the television plays the second video stream with higher definition, smoothness and compression format. And the user clicks a video recording key on the television to send a video recording instruction to the television. After receiving the video recording instruction, the television determines that the second coding capacity of the television is 1080p@30HZH264 with the highest specification in the coding capacities, and the television cannot code the second video stream with the format of 4K@30HZ. The television directly packages the first video stream with the format of 4K@30HZH265 into a recorded file, the encoding process is not performed any more, and the format of the video recorded file generated in the way is 4K@30HZH265, and the definition, fluency, compression format and the like are equal to those of the encoded video stream output by the camera. The above is merely an example, which is not limiting in this respect.

Camera supported encoding capability	Television-supported decoding capability	Coding capability for television support
			4K@30HZ H265	4K@30HZ H265	1080p@30HZ H264
1080p@30HZ H265	1080p@30HZ H265	720p@30HZ H264

TABLE 1

Therefore, the decoding capability of the intelligent device is equivalent to the encoding capability of the camera, so that the first encoding capability of the camera is set to be the highest encoding capability matched with the decoding capability of the intelligent device, the first video stream output by the camera can be ensured to be the highest specification of the camera, the encoding capability of the intelligent device is not considered, the capability that the camera can output the high-specification encoded video stream is fully utilized, and the limitation of the lower encoding capability of the intelligent device is avoided. When the second coding capacity of the intelligent device is lower than the first coding capacity, the intelligent device directly packages the first video stream output by the camera according to the first coding capacity into a recording file, so that the intelligent device can generate a video recording file with high specification based on the first video stream with high specification, but not encode the second video stream obtained according to the first decoding capacity based on the second coding capacity, thereby improving the definition, fluency, compression format and the like of the recording video file and greatly enhancing user experience; in addition, the intelligent device directly encapsulates the first video stream, so that a complicated encoding process is omitted, the computing resources of the intelligent device are released, and the efficiency of forming video recording files is effectively improved.

Based on the intelligent device, the embodiment of the invention also provides a method for recording the following videos:

For example, the camera supports two encoding capabilities 720 p@30HZH265, the television supports 720 p@30HZH265 a decoding capability, and supports two encoding capabilities 720 p@30HZH264 and 720 p@30HZH264, as shown in Table 2. Based on the principle that the coding capacity of the camera is matched with the decoding capacity of the television and is the highest coding capacity of the camera, the first coding capacity of the camera is 720 p@30HZH265, and the first decoding capacity of the television is 720 p@30HZH265. The camera outputs a first video stream according to the first coding capability of 720 p@30HZH265, the television decodes the first video stream according to the first decoding capability of 720 p@30HZH265 to obtain a second video stream with the format of 720p@30HZ, and the television plays the second video stream. And the user clicks a video recording key on the television to send a video recording instruction to the television. After receiving the video recording instruction, the television determines that the second coding capacity of the television is 1080p@30HZH264, which is higher than the specification of the first video stream, namely the first coding capacity. Thus, the television encodes the second video stream with a second encoding capability of 1080p@30HZH264 and then encapsulates it into a video recording file. The above is merely an example, which is not limiting in this respect.

TABLE 2

step 503, the intelligent device configures the coding capability of the camera to be the first coding capability and starts the camera.

For example, the camera supports two encoding capabilities of 4K@30HZH265, 1080p@30HZH265, the television supports two decoding capabilities of 4K@30HZH265, 1080p@30HZH265, based on the principle that the coding capacity of the camera is matched with the decoding capacity of the television and is the highest coding capacity of the camera, the first coding capacity of the camera is configured to be 4K@30HZH265, and the decoding capacity of the television is 4K@30HZH265.
