Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a method for displaying a pre-monitored screen according to a first embodiment of the present application includes the following steps:
s11, converting the pre-monitoring frequency signal from a first signal format to a second signal format to obtain a converted video signal;
s12, carrying out image processing on the converted video signal to obtain a processed video signal;
s13, compressing and coding the processed video signal to generate streaming media; and
s14, the stream media is associated to the target link address, so that the stream media player plays the stream media through the target link address.
Each step of the display method of the pre-monitoring screen will be described in further detail below.
In step S11, the pre-monitoring frequency source is generally a High Definition Multimedia Interface (HDMI) signal format, and needs to be converted into a signal format suitable for other interfaces, such as a Camera Serial Interface (CSI) signal format based on the MIPI (Mobile Industry Processor Interface) standard. Of course, those skilled in the art will appreciate that the first signal format may be other than HDMI; the second signal format may be other than MIPICSI, depending on the source of the particular pre-monitor signal. The conversion of the format of the pre-monitor frequency signal may be implemented by a Converter (Converter), which may be in a hardware form, a software form, or a combination of hardware and software.
In step S12, the image Processing on the converted video signal is implemented by using an Image Signal Processing (ISP) unit, and the image Processing may be color space conversion Processing and/or image format conversion Processing, but may also be other Processing, such as linear correction, noise elimination, dead pixel repairing, color interpolation, white balance correction, exposure correction, and the like. The image processing may optimize the converted video signal for further processing.
In step S13, compression encoding the processed video signal to generate streaming media is performed by using a codec unit. The compression coding may be h.264 compression coding or h.265 compression coding. The 1080P resolution 30Hz refresh rate streaming media coded by the H.264 format compression algorithm needs about 4Mbps of network bandwidth, and the network deployed by departments such as general governments, public security, schools, traffic police and the like can meet the bandwidth requirement. The compression efficiency of the H.265 format is higher, the requirement on network bandwidth is lower, and more people can watch the video simultaneously.
In step S14, the streaming media is used as a playback source and is associated with a target link address, where the target link address is a Uniform Resource Locator (URL) address, which may be a website of a local area network such as ethernet or an internet website. The association action is realized through a Streaming media Server (Server), which is built on a System-on-Chip (SOC) and may be a Real Time Streaming Protocol (RTSP) Streaming media Server, a Real Time Messaging Protocol (RTMP) Streaming media Server, or other types of Streaming media servers. After the streaming media is associated with the target link address, one or more users can play the streaming media through the target website by using a streaming media player at a computer (PC) terminal or a handheld device terminal. The streaming media player is not limited, and may be various streaming media players commonly used in the current network.
As can be understood by those skilled in the art, the embodiment of the present application achieves two technical effects by generating streaming media from the pre-monitor frequency signal and associating the generated streaming media to the target link address: on one hand, the pre-monitoring of the pre-monitoring frequency signal can be realized in a long distance because the pre-monitoring frequency signal is not limited by a cable of the pre-monitoring frequency signal due to network transmission; on the other hand, the method is not restricted by the pre-monitoring equipment and does not increase the expense of the pre-monitoring equipment, and the pre-monitoring of the pre-monitoring frequency source can be realized through various modes such as a computer terminal, a handheld equipment terminal and the like, so that better use convenience is provided.

The converter 12 is configured to convert the pre-monitor frequency signal provided by the pre-monitor frequency source 11 from a first signal format to a second signal format to obtain a converted video signal. The pre-monitor frequency signal provided by the pre-monitor frequency source 11 is generally in an HDMI signal format, and needs to be converted into a signal format suitable for the SOC13, such as an MIPICSI signal format. Of course, it will be understood by those skilled in the art that the converter 12 may convert between other signal formats in addition to converting the pre-monitor signal from HDMI to MIPICSI.
The system-on-chip 13 is configured to perform image processing on the converted video signal to obtain a processed video signal, perform compression coding on the processed video signal to generate a streaming media, and associate the streaming media with a target link address, so that a streaming media player plays the streaming media through the target link address.
Specifically, the image signal processing unit 131 is configured to perform image processing on the converted video signal to obtain a processed video signal. The image processing may be color space processing, image format processing, etc., but may also be other processing, such as linear correction, noise removal, dead pixel inpainting, color interpolation, white balance correction, exposure correction, etc. The image processing may optimize the converted video signal.
The codec unit 132 is configured to perform compression coding on the processed video signal to generate streaming media. The compression coding may be h.264 compression coding or h.265 compression coding. The 1080P resolution 30Hz refresh rate streaming media coded by the H.264 format compression algorithm needs about 4Mbps of network bandwidth, and the network deployed by departments such as general governments, public security, schools, traffic police and the like can meet the bandwidth requirement. The compression efficiency of the H.265 format is higher, and the requirement on network bandwidth is lower.
The streaming media server 133 is configured to associate the streaming media as a playing source to a target link address, where the target link address is a Uniform Resource Locator (URL) address, and may be a website of a local area network, such as an ethernet, or a website of the internet. The streaming server 133 may be an RTSP streaming server, an RTMP streaming server, or other type of streaming server. After the streaming media is associated with the target website, one or more users can play the streaming media through the target link address by using a streaming media player at a computer (PC) terminal or a handheld device terminal. The streaming media player is not limited, and may be various streaming media players commonly used in the current network.
As will be understood by those skilled in the art, the SOC13 also integrates a Central Processing Unit (CPU), a memory, and the like. It should be noted that, in other embodiments, the Image Signal Processing (ISP) unit 131, the codec unit 132 and the streaming Server (Server)133 may not be integrated on the SOC13, but may be independent elements.
As will be understood by those skilled in the art, the embodiment of the present application achieves two technical effects by building the streaming media server 133 on the SOC13 and associating the pre-monitored frequency signal provided by the pre-monitored frequency source 11 into streaming media to the target link address: on one hand, network transmission is not limited by cables of the pre-monitoring frequency source 11, and pre-monitoring of pre-monitoring frequency signals can be realized in a long distance; on the other hand, the method is not restricted by the pre-monitoring equipment and does not increase the expense of the pre-monitoring equipment, and can realize the pre-monitoring of the pre-monitoring frequency signal in various modes such as a computer terminal, a handheld equipment terminal and the like, thereby providing better convenience.
