Digital video transmission using wireless technology is an important functionality in multimedia communication. Such wireless transmission considers various parameters of channel like reliability, quality of service (QoS), transmission rate, transmission delay etc. User datagram protocol (UDP) is a fast transmission protocol used by most of the real-time(More)
To improve the robustness of video transmission over heterogeneous wireless network various error resilient tools are deployed. The impact of bit errors on the perceived video quality depends on several factors, such as error resilience of the data format, error concealment mechanism used and characteristics of the bit error pattern. In this paper the(More)
In recent days, the introduction of third component in conventional turbo codes proved to be effective in improving the code performance. In such third component enabled turbo codes, the parameters such as permeability and permittivity rates seems to be very static and so such codes cannot perform under different noisy environments. In this paper, an(More)
Design and operation of an encoder involves the optimization of many decisions to achieve the best possible trade-off between rate and distortion under the given constraint on delay and complexity. In this paper, a new rate-control algorithm is proposed by optimal bit allocation and macroblock mode selection. It is low-complexity, single pass algorithm(More)
