  • Patent number: 8260263
    Abstract: A video messaging service is compatible with multiple transport technologies (such as 2G and 3G networks), and operable to render an integrated video message having voice and corresponding video in a matter consistent with the capabilities of the recipient device. The video messaging service receives a voice (audio) and identifies a video component, computes a video format compatible with an intended recipient device, and generates an integrated video message renderable on the recipient device. The video messaging service identifies the initiator and recipient as 2G or 3G network conversant, and identifies the rendering capabilities of the recipient device, such as memory and mailboxes. The system employs MMS (Multimedia Message Service) to encapsulate independent audio and video components as an integrated message including a voice message and a video source. Depending on the capabilities of the recipient device, a .gif ( ) video rendering or a so-called 3GP rendering is also provided.
