When these patterns are identified, certain predefined sequences of lights or effects can be activated. The programming of illumination and effects control file for the entire duration of the content can be carried out in this manner. Once the entire programming is completed, this can be converted into a second video package (master DLEP) in reference with a time code track to form the DLEP. The same time code track can be inserted in the audio track of the audio file. Hence the time code track from the master DLEP can synchronize the master DLEP. Each master DLEP can have a unique serial number in the time code track. This can help identify particular master DLEP when a number of them are loaded on the playback server together. The playback server can match the content serial number of the incoming time code from the cinema server and play the corresponding master DLEP.

[00097] FIG. 9 illustrates an exemplary a block diagram showing the major components of lighting system of the proposed system, in accordance with an embodiment of the present disclosure.

[00098] As illustrated, the lighting rigs can be of different types of lights installed in a fixed layout. This layout remains constant for every setup irrespective of the location like cinema or home. However, the number of lighting rigs can differ as per the size of the location. The sizes can be classified into three broad categories - approx. 30ft, approx. 60ft and approx. 90ft length from screen to back wall. Different combinations of lights with different powers are configured as per the size category. For example 30ft size has 4 nos moving heads on the side wall. This becomes 8 for 60ft and 12 for 90ft. In the 30ft setup, each of the 4 lights move individually. However, in the 60ft setup, the lights move in groups of 2 and in the 90ft setup, the lights move in groups of 3.

[00099] The sensors can be fitted on the opposite walls to measure the intensity of the light. There are sensors fitted on the back wall to measure the intensity of the projector. A calibration system can calibrate the intensity of each light to achieve standardization across different location. The overall intensity can then again be readjusted in respect to the illumination of the projector by projecting a white frame and measuring the light output. This can ensure that the correct ratio is maintained between projection and lights. Effects devices like fog machines and wind blasters can also be installed. This ensure that the light beams are visible. Normally, otherwise, the light can be visible only on the surface where it falls. Once the path contains some fog, the entire beam becomes visible.

[000100] FIG. 10 illustrates an exemplary illustration for identifying a white flash transition in a video frame by the proposed system, in accordance with an embodiment of the present disclosure.

[000101] As illustrated, in an embodiment, the computing unit 102 can be configured to detect at least one white video frame between two video frames of the video file and generate a corresponding second set of control signals based on the detected at least one white frame. The lighting rigs 116 and the effects devices 118 can be configured to receive the second set of control signals from the computing unit 102 and provide a white coloured illumination at cinema or home for a first predetermined period of time.

[000102] FIG. 11 illustrates an exemplary illustration for identifying a lightning effect in a video frame by the proposed system, in accordance with an embodiment of the present disclosure.

[000103] As illustrated, in an embodiment, the system can be configured to generate a third set of control signals when one or more elements present in the extracted at least one video frame remains unchanged and a fluctuation in a luminance value of the corresponding video frame is detected. The lighting rigs 116 and the effects devices 118 can be configured to receive the third set of control signals and provide a lightning effect at cinema or home for a second predetermined period of time

[000104] FIG. 12 illustrates an exemplary illustration for identifying music and beats in an audio frame and a color scheme in a video frame by the proposed system, in accordance with an embodiment of the present disclosure.

[000105] As illustrated, in an embodiment, the system can be configured to extract at least one audio frame from the plurality of audio frames and detect one or more acoustical attributes form the extracted at least one audio frame. The one or more acoustical attributes can include any or a combination of intensity, pitch, frequency, amplitude, beats per minute, and signal to noise ratio. [000106] In an embodiment, the computing unit 102 can identify music and the beats along with the color scheme of the lighting rigs 116. The system can detect the presence of music in the music track along with the beats at regular interval. From the time period between 2 beats, it gets the beats per minute. The computing unit 102 can then identify a color scheme from the picture. Based on the identified beats per minute and the color scheme the lighting pattern of the lighting rigs 116 an be triggered.

[000107] FIG. 13 illustrates an exemplary illustration for identifying an explosion in an audio frame and generating a corresponding fire effect in cinema or home by the proposed system, in accordance with an embodiment of the present disclosure.

[000108] As illustrated, in an embodiment, the system can be configured to detect an explosion sound in the at least one audio frame when the detected one or more acoustical attributes in the at least one audio frame exceeds a predefined level for a predefined period of time. The system can be configured to generate a fourth set of control signals when the system detects the explosion sound in the at least one audio frame and an average value of the most dominant color in the at least one video frame corresponding to the at least one audio frame is detected to be any or a combination of red and yellow. The lighting rigs 116 and the effects devices 118 can be configured to receive the fourth set of signals and provide a fire effect at cinema or home.

[000109] In an embodiment, the computing unit can be configured to generate an illumination and effects control file based on the first set of control signals, the second set of control signals, the third set of control signals, and the fourth set of control signals. The system can be configured to generate a second video package comprising the audio file, the video file and the generated illumination and effects control file.
