System and method for coding and decoding of an asset having transparency

A method for decoding of a combined asset, the combined asset comprising one or more sequential combined frames, each combined frame comprising a first sub-image in proximity to a second sub-image, the method executed on at least one processing unit, the method comprising:

• receiving the combined asset;
• generating one or more sequential first portions and one or more sequential second portions by splitting each combined frame, the first portion comprising the first sub-image, the second portion comprising the second sub-image;
• and
• generating one or more sequential output frames in an output asset by:
• for each frame, assigning a value for a red channel, a green channel, and a blue channel for each pixel of the output asset frame with a value of the red channel, the green channel, and the blue channel of a respective pixel in the first portion respectively;
• and
• for each frame, assigning a value for a transparent channel for each pixel of the output asset frame with a value of a respective pixel in the second portion, the value of the transparent channel in the output asset is assigned the value of any one of a red channel, a green channel, and a blue channel in the combined frame that was assigned a value of the transparent channel of a frame image of an asset coded into the combined asset.

A system for coding of an input asset, the input asset having at least one area comprising a transparency, the asset comprising one or more sequential frames, the system comprising at least one processing unit and a data storage, the at least one processing unit in communication with the data storage and configured to execute:

• an obtainment module to receive the input asset, and obtain a frame image for each frame in the input asset, the frame image having a value for each of a red channel, a green channel, a blue channel, and a transparent channel;
• a coding module to generate a first sub-image and a second sub-image from each frame image, the first sub-image comprising a mask generated from the transparent channel, the second sub-image comprising a red channel, a green channel, and a blue channel generated from the red channel, the green channel, and the blue channel of the frame image respectively, and associate the first sub-image with the second sub-image, the first sub-image is generated by assigning, for each pixel, the value for such pixel in the transparent channel to the value for a respective pixel in at least one of the red channel, green channel, and blue channel of the mask;
• and
• a compiler module to generate a combined asset comprising one or more sequential combined frames, each combined frame comprising the first sub-image associated with the second sub-image.
