Basic Video Streaming Problems - Essay Example However, there are several drawbacks related to the concept of video streaming. Video streaming has its limitations on the internet because internet does not give any surety of any fixed bandwidth, delay or packet loss. It works on a â€Å"best effort service† (Apostolopoulos et al. 2002). These are considered to be variable factors that change with respect to the quality of internet connection. There have been many researches carried out over the years to induce more reliability and consistency in video streaming. These three issues are discussed in detail: As stated earlier, the bandwidth between two nodes is variable and might not be known. This variability causes problems in the traffic flow from one point to the other (Wu et al. 2001). If the sender sends data at a rate which is faster than the available bandwidth then congestion and low quality streaming is resulted. On the contrary, if the sender sends data at a rate which is slower than the available bandwidth then the receiver decodes a sub-optimal video quality (Apostolopoulos et al. 2002). A strategy to overcome this problem is to ensure a bandwidth that is acceptable to both the nodes; this can be done by estimating the available bandwidth and striking a balance between the estimated bandwidth and video bit rate transferred over the link. The degree of this issue varies from packet to packet. The variation in the delay of every packet depends on its respective queues on different routers. If there exist some variations in the end-to-end delays then it is known as delay jitter (Apostolopoulos et al. 2002). The main reason behind this problem lies in the fact that the receiver is designed to decode and thus display frames at a certain rate. Some frames may arrive at the receiver late due to this delay jitter; this can create a problem at the receiver because he is programmed to decode the frames at a certain rate. These late frames will cause jerks in the display of

Providing financial services to depository institutions, the U.S. government, and foreign official institutions, including playing a major role in operating the nation's payments system. Discussion Since the Federal Reserve Act of 1913 the Federal Reserve has been in governance of monetary policy. The policy is controlled by maintaining open market operations, reserve requirements, and discount rates (Monetary Policy, p.1). In section 2A of the Federal Reserve Act the objectives of the monetary policy read â€Å"The Board of Governors of the Federal Reserve System and the Federal Open Market Committee shall maintain long run growth of the monetary and credit aggregates commensurate with the economy's long run potential to increase production, so as to promote effectively the goals of maximum employment, stable prices, and moderate long-term interest rates† (About the Fed, p. 1). In this process the primary function of the central bank is to increase the credit and cash flow. The way this task is completed is by acting as a hub for the Federal Open Market Committee (FOMC). The Federal Reserve Bank relinquishes the funds from depository institutions into public funds. ... 1). Generally in order for the central bank to be successful at this agenda there has to be something of monetary value. The basic function of money is used as a stake horse for the Reserve bank. When the economy is in high demand of currency the Federal Reserve Bank issues it to institutions. When the demand for cash is low the bank will recover money from institutions and allow them to access a credit account (The Structure of the Federal Reserve, p. 1) These involvements along with the influence of the monetary policy will have a visible impact on the economic state. In light of the recent recession there has been some progress made toward fulfilling the monetary policy. The Federal Reserve Chairman, Ben S. Bernanke, made a testimonial over the recent effects of the economic recovery. Based on his report the new monetary policy has not yet had a positive effect. According to the report given by Bernanke the objective for the Federal Reserve to maximize employment and stabilize pri ces is near but offset by an expected decline of employment in 2011. It is expected that with the policy in place the unemployment rate will go down to 8% by 2012. The effects of the currently high unemployment rates force the economy into lower inflation periods. That force places us in range for deflation and is the cause of less production (Bernanke, p. 1). To enforce a consistent upward turn in the objectives of the monetary policy several Acts have been implemented. Of the lot, the Government Performance and Results Act Strategic Planning Document (2008-2011) outlines that the monetary policy goals will be met using the following objectives: 1. Stay abreast of recent developments in and prospects for the U.S. economy and financial markets, and in those abroad, so that monetary
