The problem how to convey maximum distinguishable video information while consuming minimum resources has long been investigated since Shannon's source channel separation theorem. The theorem is derived under the condition that all transmission errors can be corrected by the channel coding to an arbitrarily low probability. However, such a condition usually does not hold in a practical mobile video communication system given the limited resources, such as time, bandwidth, power and space. Therefore, the problem in a practical system can be formulated by "Given the source, channel, resources...
