Wireless integrated security controller
First Claim
Patent Images
1. A method for improving transmission of video information over a wireless network comprising:
- the selective application of erasure coding to a digital video data stream according to the type of video frame, wherein additional erasure coding is applied to I video frames as opposed to B or P video frames;
interleaving data at the transmitter, wherein said interleaving resequences a set of data packets before transmitting them to a receiver;
allocating blocks based upon detection of one or more errors;
monitoring a health of said network;
applying a MAC layer protocol enhancement; and
receiving selective acknowledgement from said receiver and retransmitting more important packets as requested by said receiver.

Abstract
A system and method are disclosed for improved video transmission, particularly in security settings. An improved security controller combines the interfaces and functionality for high quality video delivery over often less-than-perfect wireless networks, multi-camera analog/digital video controllers and encoders, multi-frequency wireless camera support, connectivity for serial controllers, network switching, and distributed digital video recording with optional object and motion detection. The video transmission in enhanced using wireless adaptive video encoding, mobile viewing optimization, and wireless bandwidth improvement.
