Speckle Noise Reduction in Fiber Optic Analog Video Transmission Using Semiconductor Laser Diodes
IEEE Transactions on Communications, 1981This paper investigates the effects of speckle noise on analog video transmission systems using semiconductor laser diodes. The system linearity degradation due to speckle noise is examined using different fiber types. Then this paper proposes a new modulation technique employing a superimposed pulse scheme to reduce speckle noise. It is experimentally

Analog and digital wireless video transmission: a survey
Twelfth International Conference on Signal Processing Systems, 2021With the development of wireless video services, more video transmission schemes have emerged. Because of the cliff effect and a rapid decline in signal quality, the traditional wireless transmission scheme for broadcast and mobile application scenarios has some disadvantages.

Analog Versus Digital Antijam Video Transmission
IEEE Transactions on Communications, 1977This paper presents an evaluation of the relative performance provided by analog and digital video modulation approaches. Antijam (AJ) performance of these modulations is considered when used in concert with spread-spectrum techniques such as frequency hopping, and direct sequence pseudorandom modulation. These modulation approaches are compared on the

Optical-Fiber Video Transmission Using Analog Baseband Modulation
IEEE Transactions on Cable Television, 1978Optical-fiber technology provides a new medium for the transmission of video signals. Some of the advantages which optical fibers have over coaxial cables are: wide bandwidth without the need for equalization; freedom from RFI, crosstalk and loop problems; low attenuation; and small size and low weight.

Hybrid digital-analog scheme for video transmission over wireless
2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013In this paper, we propose a novel wireless video transmission scheme named HDA-Cast, which is a hybrid digital-analog (HDA) coding scheme that integrates the advantages of digital coding and analog coding. Relative to most state-of-the-art video transmission methods, it avoids the “cliff effect” provided that the channel quality is within the expected ...

Cooperative Hybrid Digital-Analog Video Transmission in D2D Networks
2018 25th IEEE International Conference on Image Processing (ICIP), 2018In this paper, we propose a cooperative video transmission scheme in D2D networks. This research is motivated by the growing interests in hybrid digital-analog video transmissions and device-to-device (D2D) communications. The framework of D2D communications can be generally modeled as a three-node network.

Analog video transmission systems
LEOS '95. IEEE Lasers and Electro-Optics Society 1995 Annual Meeting. 8th Annual Meeting. Conference Proceedings, 2002Analog video systems have been around for a long time. Although digital video is receiving extensive media coverage, analog video will continue to exist for many years to come, In this presentation, some important issues concerning analog video transmission systems are addressed. The role of analog video in future digital world is discussed.

Recursive Distortion Estimation for Hybrid Digital-Analog Video Transmission
2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018Recently, hybrid digital-analog (HDA) video transmission scheme has shown advantages in avoiding the cliff effect. However, most HDA schemes assume perfect transmission of digital signals, which is hardly the case in practice. This paper proposes a scheme named RDE-HDA that recursively estimates the decoder-side distortion from the encoder-side for HDA

Lightwave analog video transmission techniques
Optical Fiber Communication, 1990Subcarrier modulation has become an attractive technique for the transmission of digital,1 FM,2,3 and more recently amplitude-modulated (AM) vestigial-sideband (VSB) video information.4 Although the technology for FM or digital systems has long been in place, the popularity of such systems is limited by the incompatibility of the transmitted format ...

Progressive pseudo-analog transmission for mobile video live streaming
2015 Visual Communications and Image Processing (VCIP), 2015Mobile video live streaming is facing great challenges in offering high quality of experience (QoE) under varying channel conditions. In this paper, we propose a progressive pseudo-analog transmission scheme in which the received video quality gracefully adapts to both SNR and bandwidth variations.
