       BACKGROUND OF INVENTION 
       [0006]    The present invention is in the technical field of video content. More particularly, this invention relates to the technical field of shooting and recording videos (with audio) with a mobile or other video recording device. It includes the process where a predefined or automated method is used to record a certain amount of time in one direction and followed with another period of time recording in other directions. Within the scope of this invention the recording device may be a single unit, yet have front and back microphone or camera and even more cameras pointing in different directions, and when the recording begins, it can record via the camera and microphone on the front of the device, and after a certain predefined time may automatically switch to the back or any other camera and microphone and record with those. 
         [0007]    Video and audio recording has been used to capture and document events. Expensive and hard to manage devices are often used by several people involved to do the recording. In recent years, more and more devices have been made and shipped and they include the popular handsets, smartphones or tablets. They may record easily at the touch of few options on the screen. They include front and back cameras, and the user can use either the front camera, then tap the button to switch control to the back and record with the back camera. 
         [0008]    In current methods of operating recording sessions at least 2 people are needed to achieve the same result. For example a reporter and the cameraman. While the reporter speaks the cameraman points the camera at the reporter and records the reporter&#39;s introduction, then the cameraman redirects the camera to another direction and records another scene the reporter is discussing or presenting. 
         [0009]    This invention unifies the two processes and eliminates the need for more than one person. 
       BRIEF SUMMARY OF INVENTION 
       [0010]    This invention is the method of automating or predefining the tasks of different directional recordings into one simple recording sequence, thereby with one person and one device the recording can begin with the front camera of the device and then automatically switch control to the back camera of the same device and continue recording with the back camera, or any other camera the user determines. 
         [0011]    Most recordings have the need to record different views from different directions, then combining the different directional recordings into one unified stream. For example recording of an introduction or a beginning part can be recorded first. This can be done with the use of the front camera. Soon after such introduction the person has to physically rotate the camera to the other side to continue to record the other side of the scene, yet this records unwanted areas between the front and back directions, and is not professional and is not desirable. 
         [0012]    The user can also stop the front camera recording and switch control to the back camera and start recording with the back camera. This is not very efficient and it creates two separate video clips which then need to be merged. 
         [0013]    This invention is the method by which by selecting a Switching Video mode of the device, the front camera begins to record for a predefined length of time and then the device automatically switches control to the back camera and the recording continues with the back camera. Other options for determining when the device switches from one camera to another include a hard button trigger, or a soft trigger such as a voice command.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0022]    This invention is the method of switching from one camera and microphone to another to take different directional recordings from different cameras and create one simple recording sequence, thereby with one person and one device the recording can begin with the front camera and then automatically switch control to the back camera or any other camera embedded in the device and continue recording with the chosen camera. 
         [0023]    During the recording sessions of current technologies, usually 2 or more people are needed to achieve the same result. The Cameraman uses the camera to record the video and audio of the reporter first, and after the reporter&#39;s introduction the cameraman points the camera to another direction and records the scene in question. Even by using two people in such a case, the cameraman has to stop and reorient the camera and restart the recording in the next direction, or if the cameraman continues recording while changing direction then the recording session may capture other unwanted scenes between the Reporter scene and the final scene. 
         [0024]    This invention automates this process, and enables only one person to both act as the reporter and the cameraman by using the same one device equipped with front and back cameras, and other directions, and utilizing this invention of Automatic Video switching. This produces, easy, multi-direction recording and it produces a merged sequence of recordings in one step. 
         [0025]    This invention includes several methods of recording for the Switching Video. The additional methods include: (i) Preset time for Front camera, (ii) Hard tap/Trigger to switch cameras, (iii) Soft embedded trigger to switch cameras. (iv) Front-Back-Front Camera method, (v) Multi-Camera method, (vi) Simul-record method, and (vii) sending content to other connected devices. 
         [0026]    (i) Preset time or Front Camera method provides the options for the user to start the recording with the front camera, where the time allocated for the front camera to record the introduction part pointed at the person is preset to a certain defined length of time, such as 5 or 15 or 30 seconds or any length of time selected by the cameraman. When the person starts to record, as soon as the preset time is reached the device automatically switches controls to the back camera and continues recording with the back camera until the user stops the recoding. 
         [0027]    Buttons on such devices can be mechanical or motion sensitive where the user must press or depress the button to start or stop an action of recording. In recent years, touch sensitive screen interface has been built, where the simple tap on an icon or an area on the screen will trigger and action. Some of the common ones are the Apple i-phone or Android Operating system-driven smart phone devices. These devices are loaded with specific software that show buttons and options on the screen, and the user simply taps on any icon on the screen to activate its function. Such i-phone or Android smart phone devices have also been built with two cameras, one on the front side and the other on the back side of the device. While cameras can capture video, a corresponding microphone captures the audio of the same video event. The device can be equipped with one microphone that captures the sounds from any direction, or can have one microphone on the front side that records the audio of the video recording being captured by the front camera, and another microphone on the back side of the phone that records the audio of the video recording being captured by the back camera. In all cases, the camera device, through its hardware and software combines the video (from the camera) and audio (from the microphone) to provide a unified video recording that includes video and its sound. In all cases where we refer to camera recording we refer to both the video and its corresponding audio recording done together. 
         [0028]      FIG. 1-1  shows the icon that the mobile device user taps in order to activate the front camera.  FIG. 1-2  shows the live image being captured by the front camera.  FIG. 1-3  shows the button the user must tap in order to begin the recording. The user then keeps their finger tapped on the said button to continue recording. Recording will stop when the user un-taps or removes their finger from that button. The same effect can be achieved by the use of another program application loaded in the same device, where the recording software application does not require the user to tap and hold on the button to continue recording, but rather the simple gesture of tapping once on the button begins the recording, and then tapping it again could stop the recording. 
         [0029]      FIG. 2-4  again shows the image being recorded;  FIG. 2-5  again shows the button to tap and hold to record.  FIG. 2-6  shows the timer that the user pre-sets for the duration of the front camera to record (in the case of the illustration, 5 seconds). As the user taps the recording button, the timer counts down to 0, after which the recording by the device automatically switches to the back camera and begins recording the content being captured through the back camera view. 
         [0030]      FIG. 3-7  shows the view through the back camera after the device has switched from the front to the back. At this point, the recording direction has gone from front to back camera.  FIG. 3-8  shows the recording button that the user continues to hold while the back camera continues to record.  FIG. 3-9  shows the pre-set duration the user has set for the back camera to record (in the case of the illustration, 15 seconds). As the user continues to record, the timer counts down to 0, after which the recording ends. The user can also simply remove their finger from the recording button to end the recording at any time. The same effect is also achieved by having the device start the recording when the user taps on the record button, the recording will record the first 5 seconds via the front camera, then will switch control to the back camera and continue recording on the back camera, until the user taps the record button again which will stop the recording. 
         [0031]    (ii) The hard tap/trigger method to switch cameras provides the options where there is no preset time for the introduction part of the recording being done by the front camera or other cameras. The user begins recording with the front camera by tapping the recording button (depicted in  FIG. 1-3 ), and when the user wishes to switch to the back camera, he or she taps the button again, causing the video to automatically begin recording through the back camera. 
         [0032]    (iii) Soft embedded trigger to switch cameras method provides an embedded soft trigger to switch cameras. For example this can be a unique or predefined word or a sound or a tonality that the person may say, at which point the program running the video switching will detect this and switch recording to the back camera. An example of this may be the words “and here it is”. The user begins recoding through the front camera by tapping the recoding button ( FIG. 1-3 ), and as soon as the person says the trigger words the switching video system detects this and switches controls to the back camera. 
         [0033]    (iv) Front-Back-Front Camera method includes a further elaboration of the basic Front and Back camera method, where recording may start with the Front Camera, then switch to the Back camera, and then for conclusion switch to the Front camera again. This can be accomplished through any of the three methods for switching: pre-set time, hard tap/trigger, or soft embedded trigger (voice). 
         [0034]    (v) Multi-Camera method includes the option that the device may have more than the two cameras, such as it may have four cameras, one on the front of the device, and three others one pointing to the right the other to the back and the other to the left. Using the same above basic methods of operating the recording, the user can control which cameras need to be activated for recording and in what sequence, using any method: pre-set times, hard tap trigger, soft (voice) trigger. 
         [0035]    (vi) Simul-recoding method includes the option that the device will record with the front and back cameras where some part of the screen shows the recording of one camera and the other part shows the recording of the other camera. Such display organization can be automatically preset by the software of the device or selected by the user, to have equal screen area on the screen such as in the top view of  FIG. 6 , or smaller and larger screen areas such as the bottom view in  FIG. 6 . When the cameraman taps the camera switch button or taps the icon, the screen rearranges the video into their appropriate positions. 
         [0036]    (vii) The method of capturing the camera and microphone switching video contents and instead of recording them to rather send them via mobile, wired, WiFi or wireless connectivity to other devices or to connected data storage services.
