Abstract: A method for supporting communications includes establishing a packet-based audio communication link with a remote device and informing a local computing device of the audio communication link. A message requesting identification of enhanced media capabilities associated with the remote device is received from the local computing device and tunneled in the audio communication link to the remote device. A tunneled response in the audio communication link is received from the remote device and forwarded to the local computing device. The response identifies the enhanced media capabilities associated with the remote device.

Abstract: A method comprises receiving a bit stream associated with at least one video image, wherein the bit stream comprises at least one macroblock header and a plurality of macroblocks. The method continues by encrypting the at least one macroblock header. The method concludes by transmitting the bit stream such that the at least one macroblock header is in an encrypted format and at least one macroblock is in an unencrypted format.

Abstract: A method for supporting communications involves establishing a communications conference that includes multiple conference participants that each provide an audio stream. Audio data packets in the audio streams are identified, and audio information from selected audio data packets is mixed to generate a conference audio stream that is communicated to the conference participants. Enhanced media packets in at least one of the audio streams are identified, and the enhanced media packets are communicated to selected conference participants.

Abstract: A method comprises receiving a bit sequence associated with at least one file, the bit sequence comprising payload data in a compressed format and characterization data that maps the compressed format of the payload data. The method continues by encrypting the characterization data that maps the compressed format of the payload data. The method concludes by transmitting the bit sequence such that the characterization data is encrypted and at least a portion of the payload data is unencrypted.
