Compression of digital video data using

A vector quantizer based on artiicial neural networks is developed for use in digital video data compression applications. A series of experiments investigating the edge performance of various distortion measures and experiments exploring various vector sizes are presented. The paper then describes a diierential vector quantizer which preserves edge features and an adaptive algorithm, Frequency...

NED: a Network-Enabled Digital Video Recorder

Recent advances in low-cost high-capacity disk drives, and low-cost high-quality video compression and decompression cards are enabling new types of digital video storage and delivery capabilities. One prominent example of this trend is the emergence of Digital (sometimes called Personal) Video Recorders (DVRs) in the home. DVRs enable the digitization, compression, storage, and time-shifted vi...

Efficient Techniques for Securing Digital Video Data

With fast developments in digital media and communication, transmission of video data over Internet is unsecured due to various security threats. Digital video should be encrypted using any of the cryptographic methods in order to prevent security threats. Cryptography is used for encrypting and decrypting the digital data. Traditional cryptographic systems are often not enough for fast transmi...

LAN Addressing for Digital Video Data

1 Abstract Multicast addressing was chosen over the broadcast address and unicast address mechanisms for the transmission of video data over the LAN. Dynamic allocation of multicast addresses enables such features as the continuous playback of full motion video over a network with multiple viewers. Design of this video data transmission system permits interested nodes on a LAN to dynamically al...
