“…MPEG-2 standardised a higher-compression algorithm than MPEG-1, yet providing a better video quality [15,16]. MPEG-2 is used in most of the DTV standards worldwide, including the DVB, ATSC, ISDB and DTMB solutions.…”

Abstract-This paper is a survey of the transmission techniques used in digital television (TV) standards worldwide. With the increase in the demand for High-Definition (HD) TV, videoon-demand and mobile TV services, there was a real need for more bandwidth-efficient, flawless and crisp video quality, which motivated the migration from analogue to digital broadcasting. In this paper we present a brief history of the development of TV and then we survey the transmission technology used in different digital terrestrial, satellite, cable and mobile TV standards in different parts of the world. First, we present the Digital Video Broadcasting standards developed in Europe for terrestrial (DVB-T/T2), for satellite (DVB-S/S2), for cable (DVB-C) and for hand-held transmission (DVB-H). We then describe the Advanced Television System Committee standards developed in the USA both for terrestrial (ATSC) and for hand-held transmission (ATSC-M/H). We continue by describing the Integrated Services Digital Broadcasting standards developed in Japan for Terrestrial (ISDB-T) and Satellite (ISDB-S) transmission and then present the International System for Digital Television (ISDTV), which was developed in Brazil by adopteding the ISDB-T physical layer architecture. Following the ISDTV, we describe the Digital Terrestrial television Multimedia Broadcast (DTMB) standard developed in China. Finally, as a design example, we highlight the physical layer implementation of the DVB-T2 standard.

“…In the following, we choose three image sizes as the specification for the sake of comparison. The small size image (640×480) is used in regular definition video [15] while the medium (1920×1080) and large (3840×2160) size image are employed in recently proposed high efficiency video coding standard (HEVC) [16]. The input image and data path have 32-bit depth.…”

State-of-the-art DWT designs focus on improving hardware utilization and memory efficiency of DWT. In this paper, we consider energy efficiency as the key performance metric. Memory (external memory and on-chip memory) energy dominates the total energy consumption. We propose a DWT architecture with an overlapped block-based image scanning method that optimizes the number of external memory accesses and the on-chip memory size. Using the overlapped block-based scanning method, the required number of external memory accesses of the proposed architecture is reduced by up to 50% when compared with state-of-the-art designs. Besides, the on-chip memory size is also reduced. We implement the proposed architecture on a state-of-the-art FPGA for various image sizes. Our design sustains up to 80.2% of the peak energy efficiency of the device. Compared with the state-of-the-art design, the proposed architecture achieves up to 58.1% energy efficiency improvement.

“…On the other hand, the sequences of Cafe and Book Arrival consist of scenes with slow motions. The maximum number of delayed and advanced frames is set to 15, which is the same length as the group of pictures (GOP) of the Advanced Television Systems Committee (ATSC) standard [13]. The parameters of the bilateral filter are set to N = 5, the standard deviation for w s = 5, and the standard deviation for w r = 20.…”

Youngsoo PARK†a) , Student Member, Taewon KIM † †b) , and Namho HUR †c) , Nonmembers SUMMARY A method of frame synchronization between the color video and depth-map video for depth based 3D video using edge coherence is proposed. We find a synchronized pair of frames using edge coherence by computing the maximum number of overlapped edge pixels between the color video and depth-map video in regions of temporal frame difference. The experimental results show that the proposed method can be used for synchronization of depth-based 3D video and that it is robust against Gaussian noise with σ = less than 30 and video compression by H.264/AVC with QP = less than 44.
