Web-based live broadcast

A method for a live web-based broadcast, comprising:

• intercepting at least one frame of real-time graphics data from real-time graphics data captured by a camera;
• storing at least one texture object based on the at least one frame of real-time graphics data, the at least one texture object comprising a plurality of pixels;
• filtering out a reference color from the plurality of pixels in the at least one texture object;
• creating scene image data by integrating the at least one texture object into a pre-determined virtual background;
• generating a bit stream for a live web-based broadcast from encoding the scene image data;
• transmitting over a network to a server computer the bit stream for the live broadcast;
• wherein the method further comprises:
• assigning one of a plurality of colors as the reference color;
• determining a differential value between a color of one of the plurality of pixels and the reference color;
• normalizing the differential value;
• and
• determining an alpha channel value of the one of the plurality of pixels using a normalized differential value of the one of the plurality of pixels.

A non-transitory computer-readable storage medium bearing computer-readable instructions that upon execution on a computing device cause the computing device at least to:

• intercept at least one frame of real-time graphics data from real-time graphics data captured by a camera;
• store at least one texture object based on the at least one frame of real-time graphics data, the at least one texture object comprising a plurality of pixels;
• filter out a reference color from the plurality of pixels in the at least one texture object;
• create scene image data by integrating the at least one texture object into a pre-determined virtual background;
• generate a bit stream for a live web-based broadcast from encoding the scene image data;
• transmit over a network to a server computer the bit stream for the live broadcast;
• wherein the non-transitory computer-readable storage medium further comprises computer-readable instructions that upon execution on the computing device cause the computing device at least to:
• assign one of a plurality of colors as the reference color;
• determine a differential value between a color of one of the plurality of pixels and the reference color;
• normalize the differential value;
• and
• determine an alpha channel value of the one of the plurality of pixels using a normalized differential value of the one of the plurality of pixels.
