Abstract
A video communications method includes segmenting an image frame or an image frame portion into first and second source network packet blocks. The first source network packet block includes a first number of source network packets and the second network packet block includes a second number of source network packets. The method further includes encoding the first source network packet block to produce a first encoded network packet block and encoding the second source network packet block to produce a second encoded network packet block. The first encoded network packet block includes a first number of encoded network packets and the second encoded network packet block includes a second number of encoded network packets. Still further, the method includes transmitting the first and second encoded network packet blocks over a wireless network. A wireless device and a vehicle may utilize the video communications method.
