Abstract:

This thesis deals with three among the major tasks of a receiver designed for Orthogonal Frequency Division Multiplex (OFDM): i) timing and frequency synchronization, ii) channel estimation and iii) data detection. These problems are very general, since OFDM is used in many different telecommunication environments, however the techniques involved are strongly dependent on the particular scenario. Here we focus on digital video broadcasting standards for terrestrial television. Terrestrial Digital Video Broadcasting, also known as DVB-T, is a broadcasting standard from the European consortium

Abstract:

In digital video broadcasting, sometimes many sources are used. When handling this broadcast a problem is a limited interface that has a fixed number to input channels but overcapacity in data transfer rate. To be able to connect more inputs to the interface a protocol that lets the user send more than one channel on a connection is needed. The important part for the protocol is that it keeps the input equal to the output both in timing and in what data is sent. These are done by encapsulating the data and use a header containing information for recreating the input. To solve the timing constr

Abstract:

The purpose of this thesis is to detect errors in Digital Multimedia Broadcasting (DMB) transport stream. DMB uses the MPEG-4 standard for encapsulating Packetized Elementary Stream (PES), and uses the MPEG-2 standard for assembling them in the form of transport stream packets. Recently many research works have been carried out about video stream error detection. They mostly do this by focusing on some decoding parameters related to frame. Processing complexity can be a disadvantage for the proposed methods. In this thesis, we investigated syntax error occurrences due to corruption in the head

Abstract:

碩士<br>國立交通大學<br>電信工程系所<br>93<br>This thesis proposes a new encoding and decoding method which can be applied to Digital Video Broadcasting (DVB) Systems. There are many kinds of error correction codes. Low Density Parity Check (LDPC) Code gets a lot of attention recently because its coding gain is near the Shannon limit. Moreover, the decoder is easy to implement and the hardware cost is low. Conventional Digital Video Broadcasting System uses two concatenated codes, an outer code (Reed-Solomon code) and an inner code (Convolutional code), respectively. These two codes have different interleav

碩士<br>國立中山大學<br>電機工程學系研究所<br>93<br>The topic of this thesis presents a digital front end (DFE) of the digital video broadcasting over terrestrial (DVB-T). The DVB-T system is similar to most of the prior digital communication system. It is roughly divided into two major parts, one for channel coding/decoding, and the other for modulation/demodulation. The thesis is mainly focused on the DVB-T digital video broadcasting demodulation part of the receiver and the integration of a complete digital front demodulation system. The major operational processor of the DFE is a 2K/8K dual-mode FFT proce

Abstract:

Currently, the best quality video that can be viewed on our TV is at a resolution of 1920 x 1080 pixels, standardized as High-definition (HD). To view a video even bigger and better than HD, a new resolution has recently been standardized as Ultra-High- Definition (UHD) at a resolution of 3840 x 2160 pixels. However, to broadcast a UHD video using the standard broadcast method, Digital Video Broadcasting (DVB), an exclusive DVB-UHD broadcast profile is being developed, which defines parameters for the content being transmitted, the transmitter-receiver equipment, and the television disp

碩士<br>真理大學<br>數理科學研究所<br>96<br>Watching TV by mobile devices can be realistic. The DVB-H (Digital Video Broadcasting-Handheld) is one of the main standards of mobile digital TV systems. The DVB-H involves the techniques of digital TV and mobile communications such that subscribers can access multimedia information by mobile devices. This theme presents a broadcasting protocol over DVB-H for near video-on-demand services. Based on the greedy approach, the proposed method can efficiently schedule the segments of a video for transmission. As a result, the proposed method can use the bandwidth eff

碩士<br>國立交通大學<br>電信工程系所<br>94<br>In this thesis, first we introduce a new structure of dual bandpass filter applying for IEEE 802.11a/b/g. By a serial configuration of a inductive coupled-line (ICL) filter and a capacitive coupled-line filter (CCL) filter, a dual bandpass filter can be designed with a transmission zero between the two passbands. By the two-poles Z matrix analysis, we find that the transmission coefficient of the dual bandpass filter has approximately the same behavior as the individual single-band filter around the corresponding pass-band. The measurements results also agree qu

Abstract:

碩士<br>國立中央大學<br>通訊工程研究所<br>93<br>Many digital signaling applications in broadcasting use Forward Error Correction, a technique in which redundant information is added to the signal to allow the receiver to detect and correct errors that may have occurred in transmission. Many different types of code have been devised for this purpose, but Reed-Solomon codes have proved to be a good compromise between efficiency and complexity. Reed-Solomon error correction has several applications in broadcasting, in particular forming part of the specification for the ETSI digital terrestrial television stand

The present research study investigated the perceived credibility of television news in relationship to the acquisition of knowledge of digital video compositing techniques. An experiment was carried out to verify if acquiring knowledge of digital video post-production techniques affected the perceived credibility of television news. Instrumentation for the experiment included a video stimulus produced with a readily available digital video compositing software package as well as an online post-test questionnaire. A scale for perceived credibility of television news was constructed based on

The essential idea of DVB is to replace analog services with digital ones, while DVB2.0 contains a roadmap for the development of digital broadcasting technology. The purpose of DVB 2.0 is to build bridges to the world of computing and telecommunications. With the evolvements of multimedia and Internet techniques, DVB starts to develop interactive TV, of which the data comes from the data

Abstract:

The rapid growth of wireless systems has shown little sign of ceasing, due to increased consumer demand for reliable interactive services. A key component of the development has centered on satellite networks, which allows provision of services in scenarios where terrestrial systems are not viable. The Digital Video Broadcasting-Satellite Second Generation (DVB-S2) standard was developed for use in satellite broadcast applications, the foremost being video broadcasting. Inherent to DVB-S2 is a powerful forward error correction (FEC) module, present in both the Physical and Data Link Layer. Imp
