A Subband Coding Method for HDTV
نویسندگان
چکیده
This paper introduces a new HDTV coder based on motion compensation, subband codling, and high order conditional entropy coding. The proposed coder exploits the temporal and spatial statistical dependencies inherent in the HDTV signal by using intraand inter-subband conditioning for coding both the motion coordinates and the residual signal. The new framework provides an easy way to control the system complexity and performance, and inherently supports multiresolution transmission. Experimental results show that the coder outperforms MPEG-2, while still maintaining relatively low complexity.

Perfect reconstruction filter banks for HDTV representation and coding
Subband decomposition of HDTV signals is important both for representation purposes (to create compatible subchannels) and for coding (several proposed compression schemes include some subband division). We first review perfect reconstruction filter banks in multiple dimensions in the context of arbitrary sampling patterns. Then we concentrate on the special case of quincunx subsampling and der...
متن کاملSubband/VQ coding of color images with perceptually optimal bit allocation
The combination of subband coding and vector quantization can provide a powerful method for compressing color images. The use of properties of the human visual system can increase the performance of such a system and allow one to achieve very high quality reconstructed images at compression ratios exceeding 10:1. In this paper, we design a color subband-vector quantization system, and formulate...
متن کاملSignal Processing for High-Definition Television
This thesis presents new design techniques for source coding of video signals. The main application is high-definition television (HDTV), characterized by roughly twice the vertical and horizontal resolution of current systems; aggressive source coding is required to compress the large amount of video information into the relatively narrow channels envisioned for the new service. Video source c...
متن کاملA Review of Subband Coding of Seismic
In this paper, the literature published on lossy compression of seismic data using the popular subband coding technique is reviewed. The strong links between subband coding, transform coding, and the more recent discrete wavelet transform coding are described. The performance of seismic data subband coding depends on the proper choice of lter bank and frequency partitioning in the subband domai...

Communication and multimedia have been developed rapidly in recent years. Digital media and services found in daily life include, such as digital cameras, VCD (Video Compact Disc), DVD (Digital Video Disc), HDTV (High-Definition TeleVision) and video conferences. Several well-known compression schemes, such as Differential Pulse Code Modulation (DPCM)-based method (Habibi & Hershel, 1974), DCT-...
