Abstract
Minimizing bandwidth consumption in rendering dynamic content, such as video streaming. Traditional streaming video applications utilize lossy protocols that often result in degraded user experiences. A dynamic content encoder/decoder allows a server based browser application to generate vector based rendering instructions for processing by a client based browser application. Additionally, as the dynamic content changes the content to be displayed, a server based browser application generates updated vector based instructions and encoded spatial and temporal differences to minimize the data transmitted to the client based browser.
Claims20
A computer-implemented method for digital content encoding comprising:
- identifying, based at least in part on digital content, a first plurality of objects from a graphics library;
- generating a first set of processing instructions for rendering the digital content at a first point in time, wherein the first set of processing instructions instruct a vector-based graphics engine to utilize the first plurality of objects to render the digital content at the first point in time, and wherein each processing instruction in the first set of processing instructions is associated with an object of the first plurality of objects;
- encoding the first set of processing instructions into first data;
- causing presentation of the digital content at the first point in time based, at least in part, on the first data;
- identifying, based at least in part on the digital content, a second plurality of objects from the graphics library;
- generating a second set of processing instructions for rendering the digital content at a second point in time, wherein the second set of processing instructions instruct the vector-based graphics engine to utilize the second plurality of objects to render the digital content at the second point in time, and wherein each processing instruction in the second set of processing instructions is associated with an object of the second plurality of objects;
- determining that the first plurality of objects includes a first object that is also included in the second plurality of objects, wherein the first set of processing instructions includes one or more first processing instructions associated with rendering the first object, and wherein the second set of processing instructions includes one or more second processing instructions associated with rendering the first object;
- determining that a vector-based difference exists between the one or more first processing instructions associated with rendering the first object and the one or more second processing instructions associated with rendering the first object;
- encoding the one or more second processing instructions into second data based, at least in part, on the vector-based difference;
- and
- causing presentation of the digital content at the second point in time based, at least in part, on the second data.
