Motion and audio detection based webcamming and bandwidth control

A method for processing a selected video frame for transmission across a network, the method comprising:

• receiving a first video frame;
• comparing the received first video frame with a reference video frame;
• determining if the comparison of the first video frame and the reference video frame deviates from a threshold value;
• transmitting the first video frame in response to deviating from the threshold value;
• and
• discarding the first video frame in response to not deviating from the threshold value.

A video processing system configured to transmit a selected video frame across a network, the system comprising:

• a means for receiving a first video frame;
• a means for comparing the first video frame with a reference video frame to determine movement in the first video frame;
• a means for determining whether the comparison of the first video frame and the reference video frame deviates from a threshold value;
• and
• a means for transmitting the first video frame to the network in response to deviating from the threshold value.

A method for selectively transmitting video frames across a network, the method comprising:

• receiving a video frame having a first value from a video input;
• retrieving a reference video frame having a second value from a memory;
• retrieving a threshold value from the memory;
• comparing the first value with the second value to determine a difference value;
• capturing the video frame in the memory in response to the difference value deviating from the threshold value;
• transmitting the captured video frame to the network;
• replacing the reference video frame with the captured video frame so that the captured video frame is the reference video frame;
• and
• discarding the video frame in response to the difference value not deviating from the threshold value.

A system for processing at least one from a group of a video frame and an audio frame for transmission across a network, the system comprising

• an input mechanism configured to receive a frame, the frame including at least one from a group comprising a video frame and an audio frame;
• a detection mechanism configured to compare the received frame with a reference frame, the reference frame comprising a reference video frame in response to the received frame being a video frame or comprising a reference audio frame in response to the received frame being an audio frame, the detection mechanism further configured to generate a detection signal in response to the comparison between the reference frame and the received frame deviating from a threshold value;
• and
• a web cam application configured to transmit the received frame to the network in response to receiving the detection signal and configured to determine an update of the reference frame with a new reference frame.
