...analog cable TV systems like the non-addressability and the capacity constraints. In the digital addressable systems, service providers can offer more channels and consumers can select the channels of their choice.Also, the digital addressable system opens out additional business opportunities to the service providers in the form of value added and interactive services. It would enable provision of broadband and triple play (voice, video and data) services. In addition,other stakeholders in the value chain would also potentially benefit - broadcasters by way of increase in subscription revenues, government via increase in service tax collections, and customers from an enhanced television viewing experience.

...includes huge dish shaped antennas that are placed on top of the cable operator’s office or house. Customers were able to get a connection by paying a deposit and a monthly subscription charges. This set up includes the laying of cables through narrow streets and pathways alongside buildings. Any disruption to service due to rain or other reason led to poor signals transmission. Around 90 million television analog signals in India will have to be converted into digital signals in four phases as per the Cable Television Networks (CTN) Amendment Bill 2011. India's four metros - Delhi, Mumbai, Chennai and Kolkata - will replace all analog television networks with digital transmission from July 1, 2012. After this, the target will be 38 cities with a population above 10 lakh each and finally the rest of India. This has led to a rush between multi-system operators (MSOs) and DTH operators, to grab business opportunities and acquire a large subscriber base. With digitization of cable services, cable operators need to carry only digitized signals. An STB for decoding in digital format is required to get these digitized signals. Cable operators will have to provide an STB to every subscriber, resulting in an upfront cost to the customer. DTH operators who use satellite and dish antennae are well placed to corner the business from cable operators. DTH players are leaving no stone unturned to attract consumers to switch from analog cable to digital DTH services. They have been gearing...

INTERNAL GSM BSS Network KPI (MOS) Optimization Manual Key words: MOS, interference, BER, C/I, power control, DTX, frequency hopping, PESQ, PSQM /PSQM+, PAMS Abstract: With the development of the radio network, mobile operators become more focused on end users’ experience instead of key performance indicators (KPIs). The improvement of the end users’ experience and the improvement of the network capacity are regarded as KPIs. Therefore, Huawei must pay close attention to the improvement of the soft capability of the network quality as well as the fulfillment of KPIs. At present, there are three methods of evaluating the speech quality: subjective evaluation, objective evaluation, and estimation. Among the three methods, objective evaluation is the most accurate. The PESQ algorithm defined by the ITU can objectively evaluate the speech quality of the communication network. This document uses the mean opinion score (MOS) to label the speech quality after objective evaluation. This...

...2.0. 1.0 INTRODUCTION 3.1. 1.1 INTRODUCTION OF THE CASE This case is about the impact of an environmental factor (External issue) on dividend policy of the firm (Internal issue). The environmental disaster was Hurricane Katrina which was caused the huge destruction across the south-eastern United States. Because of the storm, the stock market notably fell down. Since it is possible that the price of the shares once more increase even more than before in the near future, Ashley Swenson, chief financial officer (CFO) of Gainesboro Machine Tools Corporation has the dilemma to buy back stock or to spend the money as dividend the shareholders. In fact, the question is: How can she forecast the fortune of the stock market? In the other word, what are the driving forces (as the external factors) which are affecting on internal factors such as dividend policy? 3.2. STATEMENT OF THE PROBLEM Ashley Swenson, chief financial officer (CFO) in mid-September 2005 needed to submit recommendation to Gainesboro’s board of directors regarding the company’s dividend policy. The Gainesboro’s stock also fallen 18%to $22.15 due to post impact of the Hurricane Katrina. Now, Ashley Swenson’s dividend decision problem was compounded by the dilemma of whether to use company funds to pay shareholder dividends or to buy back stock. 3.3. HISTORY OF THE COMPANY Gainesboro Corporation was a company who designed and manufactured a number of machinery parts, including metal presses, dies...

...can they be addressed. You are expected to illustrate your answer using relevant diagrams and/ or equations. ECN256 ASYMMETRIC INFORMATION ECN256 ASYMMETRIC INFORMATION Salespersons, being boundary spanners between the organization and customers, play a critical role in enhancing customer satisfaction in order to maintain the buyer–seller relationship in situations involving service failures (Naylor & Frank, 2000). Companies hire sales people as employee’s or on a commission basis. According to the question, the firm is hiring a salesperson that will be paid an hourly rate. Paying hourly rate at start is preferable compare to that of commission. Because if the firm and its product is popular and the sales person effort level is high; therefore, in order to motivate the salesperson fixed hourly rate is advisable because whether the salesperson sales or not they still have their fixed hourly rate and also is independent of how much the firm sell or their ability to sell. Unlike commission, the higher you sale the higher you are been compensated and the lower you sale the lower you are been commissioned. Salespersons that are been commissioned, tend to feel ownership of their accounts, therefore, as a result of that they are prone to leaving you and taking your customers with them. While a fixed hourly rate salesperson, may not be as driven but they may excel at service and building relationships. There are issues involved in hiring salesperson; these include; The willingness...

...Grantham 209538112 i “Seminar 4- Capital structure and information asymmetry (2013)” Abstract This study is going to discuss capital structure choices of companies in an environment of information asymmetry. Firstly we discuss information asymmetry and how firms attempt to avoid a pooling equilibrium by signalling the quality of the firm. Quality can be signalled through the use of debt. The use of long term debt is a sign that a firm can make the payment obligations of the long term debt which is shown to signal good quality. The pecking order theory makes use of a hierarchy of financing sources and indicates internally generated funds should be used first. Following this, short term debt should be used before long term debt because of the risk and costs involved. Due to the costs involved in issuing equity in an environment of information asymmetry, firms should make use of equity as a last resort. The maturity structure of debt should also match the maturities of those firms’ assets to reduce costs. Empirical evidence suggests there is no common result for which theory is followed in practice; however it is shown that small firms who are high growth firms tend to follow a pecking order and larger firms follow a trade-off model. Due to the clear complexity involved in capital structure decisions, it is advised that a company sets out its objectives before choosing a model to follow. ii “Seminar 4- Capital structure and information asymmetry (2013)” Table of...

...A SEMINAR REPORT ON DTH(DIRECT TO HOME TELIVISION) ABSTRACT DTH is a new technology and it has matured to its full potential in other parts of the world. There are many application has been found everyday for exploitation of benefits of DTH. The word ‘DTH’ is synonymous with transmission of digital video channel to home subscriber’s using a small dish antenna. The DTH utilizes a technology which enables a home to receive high speed internet broadband access data communication, voice over internet protocol (IP) telephony and much more using an open standard Digital Video Broadcasting (DVB) technology. The video channels are received with a suitable set top box. Capable of demodulating Motion Picture Engineering Group (MPEG-2) standard videos. It is for the return channel required for other services such as voice over internet protocol and broadband access data communications, that a return channel is also required for the home terminal. The return channel via the satellite is called RCS and is an open standard. Hardware compatible with DVB-RCS technology are readily available in the market in both Ku-band and C-band. DVB-RCS is an international open standard for multimedia satellite network where the return data rates in access of 2 Mbps are possible using low cost user terminals. The forward ink is usually at 40 Mbps. Today, most satellite TV customers in developed television markets get their programming through a direct broadcast satellite...

...Genichi Taguchi to improve the quality of manufactured goods and, more recently, to biotechnology [1], marketing and advertising. Taguchi methods are considered controversial among some traditional Western statisticians but others accept many of his concepts as being useful additions to the body of knowledge. Taguchi's principal contributions to statistics are: 1. Taguchi loss-function; 2. The philosophy of off-line quality control; and 3. Innovations in the design of experiments. [pic]Loss functions Taguchi's reaction to the classical design of experiments methodology of R. A. Fisher was that it was perfectly adapted in seeking to improve the mean outcome of a process. As Fisher's work had been largely motivated by programmes to increase agricultural production, this was hardly surprising. However, Taguchi realised that in much industrial production, there is a need to produce an outcome on target, for example, to machine a hole to a specified diameter or to manufacture a cell to produce a given voltage. He also realised, as had Walter A. Shewhart and others before him, that excessive variation lay at the root of poor manufactured quality and that reacting to individual items inside and outside specification was counter-productive. He therefore, argued that quality engineering should start with an understanding of the cost of poor quality in various situations. In much conventional industrial engineering the cost of poor quality is simply represented by the...

...technology. While its predecessor, 1G, made use of analog radio signals, 2G uses digital radio signals. Based on what type of multiplexing is employed, 2G technologies may be categorized by whether they are based on time division multiple access (TDMA) or code division multiple access (CDMA). Code division multiple access is a digital radio system that transmits streams of bits (PN Sequences). It permits several radios to share the same frequencies. Unlike time division multiple access, all radios can be active all the time, because network capacity does not directly limit the number of active radios. Since larger numbers of phones can be served by smaller numbers of cell-sites, CDMA-based standards have a significant economic advantage over TDMA-based standards. The main 2G TDMA standard is: * GSM (Global System for Mobile communications)--is the most popular standard for mobile phones in the world. GSM accounts for over 80% of all subscribers around the world. It makes international roaming very common between mobile phone operators, enabling subscribers to use their phones in many parts of the world. GSM differs from 1G in that both signaling and speech channels are digital. The main 2G CDMA standard is: * IS-95 (Interim Standard 95) is the first CDMA-based digital cellular standard pioneered by Qualcomm. The brand name for IS-95 is cdmaOne.

...message signal to a bandpass signal at frequencies that are very high compared to the baseband frequency. Baseband signal is called modulating signal.Bandpass signal is called modulated signal. In telecommunications, modulation is the process of conveying a message signal, for example a digital bit stream or an analog audio signal, inside another signal that can be physically transmitted. Modulation of a sine waveform transforms a baseband message signal into a passband signal. A modulator is a device that performs modulation. A demodulator is a device that performs demodulation, the inverse of modultion. A modem (from modulator–demodulator) can perform both operations. Types of modulation • Analog modulation • Digital modulation Analog modulation- The aim of analog modulation is to transfer an analog baseband (or lowpass) signal, for example an audio signal or TV signal, over an analog bandpass channel at a different frequency, for example over a limited radio frequency band or a cable TV network channel. • Digital modulation The aim of digital baseband modulation methods, also known as line coding, is to transfer a digital bit stream over a baseband channel, typically a non-filtered copper wire such as a serial bus or a wired local area network. AMPLITUDE MODULATION(AM) ■ Amplitude Modulation (AM) ❑ Changes the amplitude of the carrier signal according to the amplitude of the message signal ...

...then being a cost leader does not generate a sustained competitive advantage for a firm. The ability of a valuable cost-leadership competitive strategy to generate a sustainted competitive advantage depends on that strategy being rare and costly to imitate. Sources of cost advantage * Economies of scale Economies of scale One of the most cited sources of cost advantage for a firm is its SIZE.There is a relationship between firm size measured in terms of volume of production - and costs - measured in terms of average costs per unit of production. The optimal volume of production is reached when the average costs per unit of production is minimum. Sources of economies of scale : volume of production and specialized machines : Acompany with a high level of production, it is able to purchase and use specoalized manufacturing tools that cannot be kept in operation in small companies. volume of production and cost of plant and equipement : Ahigh volume of production may allow a firm to build larger manufacturing operations. Large-volume firms will be able to build lower per unit cost manufacturing operations and will have lower average costs of production. volume of production and employees specialization : High volumes of production are also associated with high levels of employee specialization. Adam Smith first observed that cost advantages may be associated withe the division of labor. volume of production and overhead costs : A firm with high volumes of production can...
