BANDWIDTH UTILIZATION FOR VIDEO MAIL
Video content is delivered in a bandwidth efficient manner to a destination device. The video content is analyzed and a compression operation is performed on the video content prior to delivery to the destination device. Any audio associated with the video content is maintained in synchronization with the video content. The compression of the video can be performed in a variety of manners including single transmission of static frames, combining substantially similar frames so that only a single frame representing the combination is transmitted, and only transmitting dynamically changing or active portions of the video content.

identifying a first frame group of contiguous frames of the plurality of video frames in which the video content is substantially static; and
the step of providing the processed video content to the destination further comprises providing only a single frame of the first frame group.
7 . The method of claim 6 , further comprising the steps of:
identifying a second frame group of contiguous frames of the plurality of video frames in which the video content is substantially static; and
the step of providing the processed video content to the destination further comprises providing only a single frame of the second frame group.
8 . The method of claim 7 , wherein the next frame provided after the single frame of the first frame group may be a single frame of a second frame group or a single independent frame.
9 . The method of claim 8 , wherein the audio content is synchronized with the plurality of video frames, and the step of providing the audio content further comprises maintaining synchronization of the audio content such that as the single frame of the first frame group is displayed, the audio content associated with the entire frame group is provided to the destination device and, when the next frame is provided to the destination group, the audio content associated with that next frame is provided.
10 . A telecommunications system that provides bandwidth efficient delivery of video content to a destination device on a digital wireless network, the telecommunications system comprising:
a transcoding gateway interfacing to the digital wireless network for receiving control, video and audio content and for providing response, video and audio content to the destination devices on the digital wireless network;
a message store for storing video and audio content;
a video media server interfacing to the transcoding gateway and the message store, and in response to receiving control content requesting the provision of video and audio content, being operable to:
retrieve the video and audio content associated with the control content request from the message store
process the video content through a compression technique;
provide the processed video content and audio content to the destination device in a synchronized manner.
11 . The telecommunications system of claim 10 , wherein the video media server is operable to:
process the video content through a compression technique by determining that the video content is a still image; and
provide the processed video and audio content to the destination device in a synchronized manner by providing the still image to the destination device a single time, independent of the manner for providing the audio content, and providing the audio content in a loop while the still image is being displayed on the destination device.
12 . The telecommunications system of claim 10 , wherein the video content comprises a plurality of video frames and the video media server is operable to provide the video content through a compression technique by:
determining that the video content of the plurality of video frames includes some active video portions;
separating the active video portions from static video portions; and
the video media server is operable to provide processed video and audio content to the destination device by:
initially providing and entire first frame that includes the active and static video portions; and
providing only the active portions of subsequent video frames.
13 . The telecommunications system of claim 12 , wherein the video content is a series of menu screens with menu items, the active portions of the video frames includes serially augmenting each menu item in the menu screen, and the audio content is associated with the menu items of the series of menu screens, and the video media server is operable to provide the audio content to the destination device by:
synchronizing the provision of the audio content with the video content such that as each menu item in the menu screen is augmented, the audio content associated with the augmented menu item is provided.
14 . The telecommunications system of claim 10 , wherein the video content comprises a plurality of video frames and the video media server is operable to process the video content through a compression technique by identifying a first frame group of contiguous frames of the plurality of video frames in which the video content is substantially static; and
the video media server is operable to provide the processed video and audio content to the destination device by providing only a single frame of the first frame group.
15 . The method of claim 14 , wherein the video media server is further operable to:
identify a second frame group of contiguous frames of the plurality of video frames in which the video content is substantially static; and
