A Review of Satellite Video on Demand with Evolutionary Computing

2019
As technology has developed, satellite TV has played an increasingly important role in the national economic construction. It has repeatedly provided outstanding services in situations such as earthquake relief, border posts, and foreign hotels by maintaining communication with the outside.

Smart multiplexing for satellite video transmission

16th International Communications Satellite Systems Conference, 1996
With the emergence of standards for digital video compression and transmission, digital video traffic over satellite links is on the rise. Link efficiencies can be greatly increased if multiple digital video streams are time-multiplexed and transmitted using a single carrier.

Video-Based Satellite Attitude Determination

SPIE Proceedings, 1987
The mission lifetime of future spacecraft will be greatly extended by the routine performance of repair and resupply operations. There will be significant cost and safety advantages if these operations can be performed with minimum human involvement. A key step in any such operation will be rendezvous and docking.

Digital video broadcasting: Satellite specification

Philips Journal of Research, 1996
Digital video transmission over satellite channels is described. Many systems have so far been proposed for satellite transmission, and exist in some form. Recently, the European Telecommunications Standard (ETS 300 421) has now been accepted by the Digital Audio-Video Interface Council (DAVIC) as the world standard.

Digital video broadcasting by satellite

1999
This Chapter reviews low-bit-rate digital transmission of television signals on satellites and placed it in a context of existing and developing television standards and a changing regulatory environment. Some of the systems aspects have been discussed and particular details of practical satellite systems already available commercially have been given.

Video Signals Demodulator for Satellite Communication

2013
This paper proposes a VLSI architecture to design a QPSK demodulator of video signals for satellite communication using baseband processing. The demodulator mainly consists of a multiplier, a root-raised cosine (RRC) filter designed using distributed arithmetic (DA) technique, and an adder to add I-channel and Q-channel signals.

Perceptual Video Quality measurement method for satellite broadcasting

Proceedings of the 2014 6th International Conference on Electronics, Computers and Artificial Intelligence (ECAI), 2014
Perceptual Video Quality (PVQ) is the main parameter in television (TV) broadcasting, since the best subjective video and audio quality for the viewers is the aim of any TV system. PVQ in TV satellite broadcasting is a major concern not only for satellite Direct to Home (DTH) TV providers, but it is also an important parameter for cable TV and DTT ...

Video image transmission over mobile satellite channels

Signal Processing: Image Communication, 2001
Abstract This paper addresses the transmission of low bit-rate video image sequences through mobile satellite channels to provide portable communications services to remote areas. The particularly challenging aspects of this transmission channel include (1) rapid fading and log-normal shadowing, (2) low signal-to-noise ratio (SNR) due to the noise ...
