One of the major challenges for video collaboration lies in video conferencing in low bandwidth and low cost. In this paper we discuss about a server less desktop based video conferencing application that has been built around a highly bandwidth efficient H.264 video compression technology. The proposed solution offers a low cost multiparty video conferencing solution suitable for corporate environment...
Over the years it has been observed that a hacker, finds it less difficult to break any encryption key, even though it may require large number of attempts, specially with advent of high-speed machines. Therefore, an encryption method alone is not sufficient for copyright protection and ownership authentication of stored and streamed videos. Digital watermarking techniques have been proposed for this...
This paper presents a method for adaptive rate control in a video conferencing solution over a variable bandwidth channel. The bandwidth is estimated using the round-trip delay of probe packets. Based on the estimated bandwidth, the video rate adaptation is done in two folds; one in the H.264 video encoder based on adaptive basic unit selection and the other by generation of fragments for encoding...
This paper introduces three embedded solutions based on H.264 video codec on TI DaVinci processor. These solutions are remote video consultation system for the healthcare industry, point to point video chat and place-shifting system for the consumer industry. The main value additions in these solutions are bandwidth efficiencies and at the same time a better video quality as these systems are built...
The potential need of the video compression algorithms is to decode a digital video bit-stream in different ways and it is likely that a number of different video representations may need to coexist in a single system thereby requiring a high degree of flexibility with a high performance. This paper presents a high-performance re-configurable video architecture which eliminates the inflexibility of...
