Digital Error Modulation Rate Video
 Compressed Video Communications by Abdul H. Sadka, "Compressed Video Communications" addresses the compression and transmission of coded video streams over mobile IP networks. By analysing a broad spectrum of compression techniques and error resilience algorithms this book provides realistic solutions to the problems of quality degradation and transmission error. Features include: Discussion of the real-time transmission of coded video streams over mobile IP packet networks such as GPRS and UMTS, at both application and transport level. Descriptions of relevant rate control schemes such as bit rate regulation, scaleability and resolution reduction. Evaluation of the performance of compression techniques and comparison of available video coding standards. Comprehensive overview of homogeneous and heterogeneous video transcoding algorithms and error resilient transcoders. Examination of error control in video communications including coverage of error resilience and decoder-based error concealment. Accompanying CD-ROM containing 50 video clips illustrating the temporal and spatial quality achieved by the compression techniques outlined in the text. Highlighting the quality of service issues associated with transmission over mobile networks, "Compressed Video Communication"s is an essential guide for communications engineers and multimedia systems designers. This overview of the basic technologies and applications of digital video compression will also appeal to researchers and graduate students in the field.
 Digital Signal Processing in Communication Systems by Marvin E. Frerking, A great deal of modern communications equipment is being converted from analog to digital technology. This timely book explains many of the important concepts related to digital signal processing in easy-to-understand discussions of communications techniques, data transmission, filters, and hardware. Readers are given practical information on how to apply theory and algorithms to the design of radio receivers and transmitters. Among the areas discussed are analog to digital conversion - with emphasis on noise and distortion performance; manipulation of complex signals - positive and negative frequencies, plus Hilbert transformers; digital filters - guidelines for performance in communications, plus decimation and interpolation; hardware - multiplier accumulators, fast Fourier transform processors, digital signal processors, data flow techniques in equipment, and hardware simulation and testing; and speech processing - linear predictive coding (LPC), code excited linear predictive coding (CELP), and how to digitize speech at low data rates. Development of algorithms for oscillators, detectors, modulators, automatic gain control circuits, and other devices is clearly explained. Specific algorithms are provided for AM modulation, frequency modulation, FM detection, threshold extension, audio compression, automatic gain control, and squelch circuitry. Explanations of basic concepts of digital signal processing and data transmission are accompanied by reviews of signal representations, sampling, convolution, and z-transforms. Extensive real-world examples contribute to expertise in many facets of incorporating digital technology into devices. This hands-on treatment of DSP will helpcommunications engineers upgrade their skills in digital signal processing and make a smooth transition into the design of more advanced systems. It also meets the needs of students who want to bolster their knowledge in communications.
Digital television - Digital television (DTV) uses digital modulation and compression to broadcast video, audio and data signals to television sets. Adaptive modulation - Adaptive modulation is a transmission scheme in digital communications where the transmitter adapts its transmission mode in accordance with the channel. Depending on the condition of the channel, the transmitter could be adapting one or more of the following: constellation size, code rate, and power. Average bit rate - Average bit rate refers to the average amount of data transfered per second. This is commonly refered to for digital music or video. DVB-T - DVB-T stands for Digital Video Broadcasting - Terrestrial and it is the DVB European consortium standard for the broadcast transmission of digital terrestrial television. This system transmits an MPEG-2 family digital audio/video stream, using OFDM modulation with concatenated channel coding.
