“…The well-known Lagrange-based framework used in JPEG2000 provides significant improvements, but at the expense of computation cost [5]. The solution proposed in this paper is similar with the method proposed on Rate Control based on the ρ-domain for H.264/MPEG AVC [6] for a low complexity. It mainly consists in building a global model to estimate the rate/distortion behavior of the codec.…”

-This paper presents a joint quality control (QC) and rate distortion optimization (RDO) algorithm applied to a still image codec called Locally Adaptive Resolution (LAR). LAR supports scalability in resolution for both lossy and lossless coding and has low complexity. This algorithm is based on the study of the relationship between compression efficiency and relative parameters. The RDO model is proposed firstly to find suitable parameters. Relying on this optimization, relationships between the distortion of reconstructed image and quantization parameter can be described with a new linear model. This model is used for parametric configuration to control compression distortion. Experimental results show that this algorithm provides an effective solution for an efficient one pass codec with automatic parameters selection and accurate QC. This algorithm could be extended to codecs with similar functions, such as High Efficiency Video Coding (HEVC).

“…We are focusing our research on power consumption of constant bit rate video only. One source of constant bit rate video data is a single-layer codec with rate control mechanism that helps to achieve constant bit rate of the compressed video data [36,37]. Constant bit rate transmission of variable bit rate stored video may be performed e.g.…”

a b s t r a c tThis paper presents an analysis of the power consumption of video data transmission with constant bit rate over 3G mobile wireless networks. The work includes the description of the radio resource control transition state machine in 3G networks, followed by a detailed power consumption analysis and measurements of the radio link power consumption. Based on this description and analysis, we propose our power consumption model. The power model was evaluated on a smartphone Nokia N900, which follows 3GPP Release 5 and 6 supporting HSDPA/HSUPA data bearers. We also propose a method for parameter selection for the 3GPP transition state machine that allows to decrease power consumption on a mobile device taking signaling traffic, buffer size and latency restrictions into account. Furthermore, we discuss the gain in power consumption vs. PSNR for transmitted video and show the possibility of performing power consumption management based on the requirements for the video quality.

“…On the other hand, those rate control algorithms which make use of the r (the percentage of zeros among the quantized transform coefficients)-domain source model [4] are well-known for their accurate estimation of the characteristics of the video, and show better performances in the existing video standards [6]. Many rate control algorithms were developed to attain the practicability of the rdomain source model-based rate control for H.264/ MPEG-4 AVC [5,9,13]. He and Chen proposed a rate control algorithm for H.264/MPEG-4 AVC using linear rate model also known as r-domain source model [5].…”
