seminar on wireless network devices digital convergence

The wireless network digital electronic device includes a television signal receiver, a decoder, a processor, and a wireless network signal transceiver. The television signal receiver receives the television broadcasting signals, the decoder decodes the signals, and the processor encodes the decoded signals into wireless network signals. Subsequently, the wireless network signals are transmitted to the display device using the wireless network signal transceiver.

The proliferation of mobile computing devices including laptops, personal digital assistants (PDAs) and wearable computers has created a demand for wireless personal area networks (PANs). PANs allow proximal devices to share information and resources. The mobile nature of these devices places unique requirements on PANs, such as low power consumption, frequent make-and-break connections, resource discovery and utilization, and international regulations.

Communication demands compatibility, which is challenging in a heterogeneous marketplace. Yet by establishing and implementing compatible systems, manufacturers can offer more powerful and useful devices to their customers. Since these are, after all, digital devices living in a programmed digital world, compatibility and interoperation are possible.

The future of digital era exists in a digital convergence where every device interacts with other devises to make decisions and help human being in their daily life. A TV will interact with Phone and watch to display programs related to human interest and mod. A refrigerator will inform the about the milk when an owner is passing by a super market, and many more examples can be realized in near future. A great research is being carried out in this area and it can be realized with the presence of may conferences and research papers coming everyday.

Digital Convergence in the Wireless Era
Digital convergence generally means the integration of consumer electronic devices with intelligent information management devices. When you combine digital media with the ability to manipulate audio, video, text, and binary data of all types, you can create new types of applications, new types of devices all networked together. It's an area that you as a consumer should not take lightly because this technology will become a pervasive component of your everyday life.
An entertainment network should offer you the following capabilities:
• Simple connectivity for your devices (strive for device interoperability)
• A software framework built on standard methods for device discovery, configuration, and management (such as SNMP, the Simple Network Management Protocol)
• Standard media formats and transport or streaming protocols
• A standard way of managing your media within your framework
• A digital rights mechanism that protects intellectual copyrights so that everything is nice and legal

That's a tall order to fill (particularly on the software side), but the industry can achieve it in time. You should do all you can to strive for maintaining these characteristics in any home entertainment network that you choose to build; these are the elements you should look for when you purchase and install new components that will be part of your entertainment network.
The consumer electronics market dwarfs the computer market in scale. At the Comdex and Consumer Electronics Show in Las Vegas, that difference is very obvious. Consumer applications of computer technology have been a bright spot over the past three or four years in the computer industry, and computer vendors have been rushing to position themselves for what they see as an essential emerging new industry based around a home network (see Figure 14-1). The new products being introduced seek to take advantage of developments like HDTV, surround sound, digital cameras, the Personal Video Recorder (PVR), the Digital Versatile Disk (DVD) and other new storage devices, and home automation by integrating those technologies into their products. For example:
• Microsoft offers the Windows Media Center edition operating system for the home market and both Microsoft and Intel have connected home initiatives.
• Gateway has a best-selling plasma monitor to complement one of the better Media Center PCs (the Gateway Media Center FMC-901X) on the market, which is a natural extension of the company's pioneering efforts from its Destination PCTV series.
• Apple dominates the MP3 jukebox market with its iPod series.
• Epson offers the Livingstation HDTV projection TV, which comes with a dye sublimation printer and smart media support built in allowing you to print high-definition images on demand.
• Any number of companies including HP, Sony, Netgear, D-Link, SMC, and others sell wireless streaming media hubs or receivers.

The list of computer-related products coming from the traditional consumer electronics market is also actively growing, as evidenced by the fact that
• Comcast can offer you both high-speed broadband Internet access as well as on-demand video services (see Figure 14-2).
• LG Electronics is offering a networked/Internet refrigerator (something that Motorola demo'ed as a concept in 1999).
• Westinghouse has a line of connected home appliances that use the Windows CE .NET operating system. Its line includes a microwave oven, coffee maker, and bread maker, along with a home hub with a CD/FM/clock and Internet access and the iCEBOX kitchen PC with an LCD screen and wireless keyboard.
• Omnifi's DMP2 (omnifimediaproducts/omnifi_products.jsp) car audio/video player synchronizes content with either a USB or 802.11g connection with your home media servers so that you can play it in your car.
• Motorola's Home Theater System DCP501 provides a digital cable receiver, DVD/CD/MP3 player, 100 watts by 5-channel amplifier, and an AM/FM stereo receiver in one package.
