Abstract
A method and apparatus are provided for implementing reduced video stream bandwidth requirements when remotely rendering a complex computer graphics scene. Complexity of a scene is reduced at a server, prior to rendering a video stream that comprises the scene and transmitting the video stream to a client. Reducing the complexity of a scene at the server includes adjusting predefined scene configuration parameters. The order and degree to which predefined scene configuration parameters are adjusted is based upon a required stream bandwidth reduction to be made.
Claims11
An apparatus for implementing reduced video stream bandwidth requirements when remotely rendering a complex computer graphics scene comprising:
- a processor,
- a controller tangibly embodied in a non-transitory machine readable medium used to implement reduced video stream bandwidth requirements;
- said processor using said controller, receiving action data and identification of input scene data from a client to configure preferences by each user and reducing complexity of a scene at a server, prior to rendering a video stream that comprises the scene and transmitting the video stream to a client by:
- processing each data packet to be transmitted by identifying and storing history including a packet ID, an action, and a result;
- for each data packet ID, said action including a stored action for a plurality of performance levels with said result of a performance change;
- for each data packet ID, determining performance of transmission of the video stream for a previous packet and storing said result of identified performance change in history data;
- adjusting predefined scene configuration parameters responsive to the history data including providing an order and a degree for predefined scene configuration parameters adjustments based upon a required stream bandwidth reduction to be made by providing action data including a respective background level and a respective action to achieve a selected one of a plurality of performance levels;
- storing a flag for each respective input scene data object responsive to a combination of said received action data, said identification of input scene data, and said adjusted predefined scene configuration parameters;
- creating output scene data for each object from the input scene data by performing a selected action assigned to the flag for each respective input scene data object to create objects in the output scene data, and
- rendering the output scene data into the video stream and transmitting the video stream to the client.
