Media stream mixing
First Claim
Patent Images
1. A method of forming an output media stream to be transmitted during a communication session from a portable communication device wherein said output media stream comprises signals of a first media type, the method comprising:
- generating in real time a first media stream in the portable communication device,combining in real time the first media stream with a second media stream to form the output media stream wherein combining comprises superposing, within the portable communication device, signals of the first media type from the first media stream on signals of the first media type from the second media stream to produce the output media stream, wherein the output media stream comprises portions of the first and second media streams which are configured to be presented in a substantially simultaneous time period, andtransmitting said output media stream,wherein the communication session includes a video telephony session,wherein the second media stream includes a prerecorded media stream that is user selectable, andwherein at least one of generating and/or combining is dependent on input data from a user of said portable communication device.

Abstract
The present invention is directed towards a method and a portable communication device (200) for forming a real time output media stream by mixing a first real time media stream with a second media stream. Provision of mixing of media streams provides a number of attractive functions, for instance. This invention concerns how to increase the usage of a mobile VT application and how to be able to handle integrity issues when used in a portable communication device.

-
generating in real time a first media stream in the portable communication device, combining in real time the first media stream with a second media stream to form the output media stream wherein combining comprises superposing, within the portable communication device, signals of the first media type from the first media stream on signals of the first media type from the second media stream to produce the output media stream, wherein the output media stream comprises portions of the first and second media streams which are configured to be presented in a substantially simultaneous time period, and transmitting said output media stream, wherein the communication session includes a video telephony session, wherein the second media stream includes a prerecorded media stream that is user selectable, and wherein at least one of generating and/or combining is dependent on input data from a user of said portable communication device. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 27)

19. Portable communication device configured to form an output media stream to be transmitted during a communication session from said portable communication device, wherein said output media stream comprises signals of a first media type, said portable communication device comprising:
-
at least one generating unit configured to generate a first media stream, a first combining unit, connected to said generating unit, wherein the first combining unit is configured to combine in real time the first media stream with a second media stream and wherein the first combining unit is configured to superpose, within the portable communication device, signals of the first media type from the first media stream on signals of the first media type from the second media stream to form the output media stream, wherein the output media stream comprises portions of the first and second media streams which are configured to be presented in a substantially simultaneous time period, a control unit configured to control the generating unit and the combining unit, in dependence of user input, and a transmitter configured to transmit said output media stream, wherein the communication session includes a video telephony session, wherein the second media stream includes a prerecorded media stream that is user selectable, and wherein at least one of the generating unit and/or the combining unit is configured to function in response to input data from a user of said portable communication device. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 28)
