Digital Hubbub

About

Entertainment is the major aspect of any human‘s life. This brings out the importance of consumer electronics. Consumer electronics play a very important role in today’s household entertainment devices such as TV, VCR, music systems like CD player MP3 etc. A lot of innovations are taking place in the field of consumer electronics.

Neologism In Digital Hubbub

As far as an electronic component market is considered the success of a product relies on the compactness and cheapness of the product. As any electronic device digital hubbub is also required to be compact and cheap. Compactness is brought about by implementing chips with multi-functions or in other way it can be said as compactness can be brought by merging 2 or 3 chips to do a single function. There fore several electronics firm are doing lot of research and development to bring about a much compact and cheap digital hubbub.

Hardware

At the core of a home entertainment hub are

     ·       Central Processing Unit

     ·       Digital signal processing chips 

     ·       Hard disk drive

     ·       Universal serial bus port

     ·       PCMCIA connector

     ·       Ethernet jack

Central processing unit   :- As in a computer system , CPU is the master of the hub. It deals with the data transfer that takes between different peripherals and hub. It checks on the parallel operations taking place in hub.

Digital signal processing chips :- The analog signals from various peripherals like a TV set  or a tape recorder is received by analog to digital convertors .  These digitized data is accessed   by digital signal processing chips via their serial ports.

Hard Disk Drive  :- The hard disk drive is under a direct control of CPU via disk controller. As in any device a hard disk drive is used to store the data .

Universal Serial Bus (USB) :- The USB is a synchronous protocol that supports isochronous and asynchronous data and messaging transfers.

Personal Computer Memory card International Association (PCMCIA) :- PCMCIA cards are credit card size adapters which fit into PCMCIA slots found in most handheld and laptop computers.

Software

As in a normal personal computer software checks on user interface , applications etc . Software of digital hubbub can be considered as a series of layers. In the innermost is an operating system that manages resources such as storage or CPU timing . The next layer is the middle ware that handles such house keeping details as displaying text and graphics on TV screens. The middleware interpret the input from different panel or remote control and it enables the CPU to generate signals according to the concerned function. It also deals with the communication with the cable that supplies the digital video and data strings . The outermost layer handles several applications .

A436 Parallel Video Dsp Chip Overview

    ·       Highly optimized and efficient, general purpose, very high performance, 512b advanced imaging parallel DSP and 32b RISC processor (no MMU) in a single chip in a single instruction stream

    ·       Performance of 50,000 RISC MIPS for motion estimation and 3 billion MACS with only 100 MHz CPU clock.

    ·       Achieves very high performance with moderate CPU clock rate and main-stream fabrication

Abstract

As far as consumer electronics is considered the latest talk in the town is about 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 merged company intends to roll out Moxi's software on Motorola's set-top box hardware; it is also moving forward with tests of Moxi media center prototypes among subscribers to Echostar Communications Corp. (Littleton, Colo.), a satellite TV service. Established makers of set-top boxes, including Royal Philips Electronics (Amsterdam, the Netherlands) and Pioneer Corp. (Tokyo)—and, of course, Motorola—are building boxes that include high-speed data connections and home-network capabilities, in addition to the digital TV decoders of ordinary cable systems.
