The latest talk in the consumer electronics industry is about digital hubbub. This device is used as a hub to interconnect various any home devices. Along with the interconnecting capability hub also incorporates several functions like recording, play backing etc of data streams from various electronic devices in the house. The electronic devices mentioned include a TV, VCR, Camcorder, personal computers etc. The digital hub would be expected to access high-capacity storage and data access devices provide and inputs for devices such as TV tuner, digital cameras, digital video, and broadband digital data. Apart from this it must be capable of distributing these files and information using connection mechanisms like a cable or digital subscriber line (DSL) modem on the front end of the hub. Additionally an efficient user interface is a must and should be a file browser like that of a PC desktop, modified for a TV screen, and a remote control to provide a familiar interface and ease of access. How does the Digital Hubbub system manage to solve all these challenges? What forms the internal core components of the Digital Hubbub system? Various disparate technologies will need to be married into a single device to provide control and connectivity features in an efficient manner. Another facet of the Digital Hubbub system is the Software. What will be the design of the component? The functionality of the system will directly depend on the design and power of the software layer. What will determine the future of the Digital Hubbub technology? The need for a uniform standard for product development among the product engineers is just as important as the actual device itself
Human being is always looking for single device that can be used for various purposes. We can connect various devices either it is the case of personal computers or home devices that we use in our day to day life. Interconnection is for easy accessing of information or data stored on other devices. This is fine when we are connecting the PCs but when you talk about house devices such as TV, VCR, Cam recorder, personal computers etc. It looks pretty odd. We are very much familiar about Hub. Hub is electronic device that connect Small office, home office (SOHO) applications typically use a single Hub, or an all-purpose converged device such as gateway access to small office/home office broadband services such as DSL router or cable, Wi-Fi router. We have something same device faster in comparison with hub that is Switch. A lot of innovations are taking place in the field of consumer electronics. The latest talk is about a single device which can interconnect all these entertainment devices and provide many functions such as record, archive, and playback music and videos, organize digital photo and albums, and distribute signal media around the home. So companies gave birth to a new electronic device which is known as DIGITAL HUBBUB. his device is used as a hub to interconnect various any home devices .Along with the interconnecting capability hub also incorporates several functions like recording play backing etc of data streams from various electronic devices in the house . The electronic devices mentioned include a TV, VCR, Camcorder, personal computers etc. The hub consists of a software part and hardware part. Hardware comes along with CPU. It has Digital signal processing chips in a memory and different ports for interfacing. Hard disk drive, Universal Serial bus port, PCMCIA and Ethernet jack are also core of hubbub. Software has got 3 layers an inner layer, a middle layer and an outer layer. These layers are divided on the basis of various functions they have to do. To Apple and Microsoft, it looks like a computer. To cable and satellite companies like Charter, EchoStar, or DirecTV and their suppliers, it's a set-top box. To consumer electronics companies like Philips or Samsung, it's a stereo component. Various companies are now trying to make their dream possible, as a company which brought digital hubbub. Some of the companies like Moxi digital (Palo Alto, California), Digeo Inc. (Kirkland, Washington), Motorola Inc. (Schaumburg, Ill.) and cable company Charter Communications Inc. (St. Louis, Mo.) are interested in building boxes that include high-speed data connections and home-network capabilities, in addition to the digital TV decoders of ordinary cable systems.
2. Hub as a Factotum
Factotum means an employ that does a lot of things. This is what digital hubbub does by recording, archiving, store digital photos and albums and distribute digital media around home. This can be done from sources like CD library, broadcast TV, and the internet. They will also be able to store and play video games. And they will organize all your media files in an easy-to-browse fashion and play them back on demand, making available features such as pause, rewind, and several varieties of skip and fast-forward. Typically, the digital hub would be expected to access high-capacity storage and data access devices provide and inputs for devices such as TV tuner, digital cameras, digital video, and broadband digital data. Apart from this it must be capable of distributing these files and information using connection mechanisms like a cable or digital subscriber line (DSL) modem on the front end of the hub. Additionally an efficient user interface is a must and should be a file browser like that of a PC desktop, modified for a TV screen, and a remote control to provide a familiar interface and ease of access On the output side, a digital hub would serve audio and video to every TV set, computer, and stereo in your home .This would require a wiredâ€or preferably wirelessâ€ network, with cheap receivers scattered around the house to capture the digital signals and return them to analog form. Inside, a hub may look much like an oddball PC from the last decade: a 32-bit CPU ticking over at a few hundred megahertz, with some multiple of 8MB of RAM, a video interface, and a digital signal-processing (DSP) chip or two to compress and decompress the video and transform the stored data into a format for display. It will also need 20GB of disk space and up, as good video requires about a gigabyte an hour, and audio needs about a megabyte a minute. (Once you have the CPU and DSP chips for encoding and decoding the streams of digital video compressed for broadcast or storage on a DVD, most of the other functions of a home entertainment gateway, including the user interface and music storage, are close to free).
TV, VCR, Digital camera etc. are connected by cable wire or wireless. Wireless network is done by connecting devices by cheap receivers. All heavy appliances are connected to hubbub via home network while light appliances are connected directly to hubbub by USB ports.
3. Under The Hood Under this heading we deal with the elements which make up digital hubbub. Just like a personal computer it also got a hardware side and a software side is same way it has also two parts.
• At the core of a hubbub is
• Central Processing Unit
• Digital signal processing chips
• Hard disk drive
• Universal serial bus port
• PCMCIA connector
• Ethernet jack
