The present television system was designed nearly 50 years ago. Since then, there have been significant developments in technology, which are highly relevant to the television industry. For example, advances in the very large scale integration (VLSI) technology and signal processing theories make it feasible to incorporate frame-store memory and sophisticated signal processing capabilities in a...

In the past, viewers were constrained to watch television in front of a receiver in their home. Today, people watch video at any time and in any place. A viewer can now browse video on their desktop PC, or watch a movie outdoors on a mobile handheld device, or view HDTV (High Definition Television) in their own home theater system or at Digital Cinemas within a well controlled viewing environment.

The present television system was designed nearly 35 years ago. Since then, there have been significant developments in technology which are highly relevant to the television industries. For example, advances in the very large scale integration (VLSI) technology and signal processing theories make it feasible to incorporate frame-store memory and sophisticated signal processing capabilities in ...

This thesis presents the design and evaluation of a software 8-VSB receiver for ATSC digital television (DTV). Based on an unique software radio architecture, employing wideband digitization and a conventional workstation, this receiver uses novel software algorithms to achieve carrier and timing synchronization. Carrier and timing synchronization are typically accomplished with analog techniqu...

This study was designed to explore the usability of three remote controls that operate a specific digital set top box (Logik LDR V3) amongst consumers who may have more difficulty than most in accessing and using digital television equipment. Participants were UK consumers (a) aged over 75 years with various sensory, physical and/or cognitive impairment, (b) aged under 45 years with learning di...

ITH the advent of ultra-high-frequency television and the subsequent allocation of specific UHF channels, the need for a VHF-UHF television tuner becomes apparent. This tuner should ideally make the maximum use of the same components on VHF and UHF, so that there would be a minimum duplication of parts. This design should be one which would give optimum performance and still be easy to fabricat...

Korea has made a plan to transfer from analog television to Digital Television (DTV). Therefore, TV White Spaces (TVWS)are the unused TV broadcast channels which can be available for wireless communication systems. This paper assumes that DTV operates on Channel 34 and Long Term Evolution (LTE) is assumed that it uses Frequency Division Duplexing (FDD), and then upper 4 MHz of Channel 32 and ch...

For the ATSC-Mobile DTV standard has much more training-sequence than the conventional ATSC digital television standard, in this paper, we propose a modified channel estimation structure using the additional training sequence to track the channel changes, which can fast start-up the receiver equalizer of ATSC-M/H digital television system in time varying mobile broadcasting channel. A dual thre...

This paper proposes an architecture for the development of interactive digital television systems accessible via voice. The proposed architecture is applicable to any interactive digital television application developed under the MHP standard, which runs on an interactive receiver equipped with return channel via Ethernet. The user needs only a mobile device with audio I/O, capable of running a...
