Posted on Wednesday, 24 July 2013 by

Mobile TV has become a key, if not the key, application that mobile operators need to deploy to attractnew subscribers, or simply retain their existing base. Even before the business models and killerapplications for mobile video have been fully explored, mobile operators and broadcasters already face a wide variety of mobile video distribution standards, devices, and applications that deeply impact the way in which those services are deployed.This presentation will focus on the knowledge gained from early deployments of MPEG-4 encoders for.Mobile TV. Featured highlights include case studies on the Orange 3GPP deployment, with an overview of its technical challenges as well as current requirements for successful Mobile TV deployments.Mobile TV deployments can only be considered a success if they contribute positively to an operator's business. Most operators are looking beyond user subscription fees as the sole revenue source for the service by adding revenue from targeted advertising and other paid content. Operators also see tangential benefits of improved subscriber adoption.

XML ENCRYPTION PPT FREE DOWNLOAD

by

As XML becomes a predominant means of linking blocks of information together, there is a requirement to secure specific information. That is to allow authorized entities access to specific information and prevent access to that specific information from unauthorized entities. Current methods on the Internet include password protection, smart card, PKI, tokens and a variety of other schemes. These typically solve the problem of accessing the site from unauthorized users, but do not provide mechanisms for the protection of specific information from all those who have authorized access to the site.
Now that XML is being used to provide searchable and organized information there is a sense of urgency to provide a standard to protect certain parts or elements from unauthorized access. The objective of XML encryption is to provide a standard methodology that prevents unauthorized access to specific information within an XML.

MPEG-7 Seminar ppt Free Download

by

The Moving Picture Experts Group (MPEG) is developing a new standard called the “Multimedia Content Description Interface" also known as MPEG-7. The goal of MPEG-7 is to enable fast and effective searching and filtering of multimedia content. The effort is being driven by requirements taken from a large number of applications related to multimedia databases, interactive media services (music, TV pro-grams), video libraries, and so forth. MPEG-7 is  achieving this goal by developing an XML-Schema based standard for describing features of multimedia content. In this tutorial, we study the emerging MPEG-7 standard and describe the new challenges for MPEG-7 multimedia databases.The ultimate goal and objective of MPEG-7 is to provide interoperability among systems and applications, used in management, distribution, and consumption of audio-visual content descriptions. Such descriptions of streamed or stored media help users or applications to identify, retrieve, or filter audio-visual information. Examples of applications include broadcast media selection.


Firewall ppt Free Download

by

Every computer needs a firewall. When we access internet the firewall must control(what information goes out   and what information comes in)  and protect  our  personal computer or internal network such as LAN.Firewall acts as a basic security system of our computer or internal network.One of the main function of firewall is to examine application or protocol that tries to establish a communication channel on our computer and everytime alart  the user  for takes action such as allows or block.Firewall are becoming more sophisticated day by day.A firewall provides  a single point of defense between two networks .it protects one network from another.A  firewall is software or hardware-based network security system that controls the incoming and outgoing network traffic by analysing the data packets and determining whether they should be allowed through or not, based on a rule set. A network's firewall builds a bridge between the internal network or computer it protects, upon securing that the other network is secure and trusted, usually an external (inter)network, such as the Internet, that is not assumed to be secure and trusted.Many personal computer operating systems include software based firewalls to protect against viruses from public network.Many router that controls packet data include firewall components.


OPTICAL MOUSE ppt Free Download

by


The main goal of any mouse is to translate the motion of your hand into signals that the computer can use. Almost all mice today do the translation using five components. Two rollers inside the mouse touch the ball. One of the rollers is oriented so that it detects motion in the X direction, and the other is oriented 90 degrees to the first roller so it detects motion in the Y direction. When the ball rotates, one or both of these rollers rotate as well. The following image shows the two white rollers on this mouse. On either side of the disk there is an infrared LED and an infrared sensor. The holes in the disk break the beam of light coming from the LED so that the infrared sensor sees pulses of light. The rate of the pulsing is directly related to the speed of the mouse and the distance it travels. An on-board processor chip reads the pulses from the infrared sensors and turns them into binary data that the computer can understand. The chip sends the binary data to the computer through the mouse's cord.
