… vad konsumenter anser vara en tillfredställande ljudnivå för NICAM- och MPEG-ljud i nyhetssändningar sända för kabel-TV i Luleå. Målet med studien är att se om ljudnivån är lika eller olika för respektive TV-kanaler och vilken lyssningsnivå som föredras av konsumenter …
… animations. It describes a standard for handling human face animations, the MPEG-4 Face Animation, and shows the process of designing, implementing and evaluating applications compliant to this standard. First, it presents changes introduced to the existing components of the …
… coder, network link and image player. The image coding has been focused on MPEG and wavelets. The wavelet technique is not a well known coding principle for video applications. Although as a coding technique for still images the technique is well known. For instance it is used …
… tests are made to investigate the features of the digital video standard MPEG-2. Both the coding delay and the image quality are of great interest. Another digital video standard, DV, is considered as an alternative to MPEG-2. Apart from different coding techniques, this work …
… capacity. As an environment to work with we have used a video system called QMPEGv2. A set of experiments were carried out to evaluate the performance of the algorithm. Through experiments, we show that the system can adapt to dynamic changes in network conditions and provide …
TV and radio services have always been distributed over analogue broadcasting networks and been received on a TV -set or a radio receiver. Today this situation is changing due to digitalization and convergence between broadcasting, telecommunications and data communications …
The goal of this project was to implement and compare Invere Discrete Cosine Transform using three methods i.e. by bit parallel, digit serial and bit serial. This application describes a one dimensional Discrete Cosine Transform by bit prallel method and has been implemented by …
… vector quantization, in spite of it's simplicity, has clear advantages over MPEG-4 encoding.
IDCT (Inverse Discrete Cosine Transform) is a common algorithm being used with image and sound decompression. The algorithm is a Fourier related transform which can occur in many different types like, one-dimensional, two-dimensional, three-dimensional and many more. The goal …
En studie av strömmande videoprotokoll
… på vilka protokoll som dom använder.Rapporten undersöker även hur Apple och FFmpeg har implementerat HTTPLive streaming med avseende på hur mycket data som behövs läsas i en filinnan videon kan börja spelas upp. Rapporten visar att det inte är så storaskillnader mellan de fyra …
