For the slogan "Digital Family", even those who are not familiar with digital technology should be heard by the manufacturers and the media. Despite this, there are not many people who really understand the concept of "digital home", let alone the dream of creating a "digital family."
In fact, the digital home is not complicated, and in the current mature digital home computer and peripheral equipment, the average consumer wants to own his own digital home environment. Apart from budgetary considerations, the technical aspect is not a problem. As long as you understand the concept of a digital home, it may be easier to practice it than you think.
What is a digital home?
To be honest, there is currently no clear definition of the digital family. Different vendors in different fields have their own opinions, but the basic concepts should be common.
One simple statement is that “the digital home is centered on the living room and links all digital devices to integrate the multimedia entertainment needs of family membersâ€.
The concept of such a concept is the digitization of the "living room". The traditional living room is positioned in the family, in addition to being used to receive guests, more time is the entertainment place where the whole family gathers. Watching TV, watching movies, and singing karaoke together, the living room not only brings together "family", but also a place where all kinds of audio-visual appliances gather.
The broader digital home is not limited to multimedia applications. Other expansion concepts include: home appliance control, home website, security monitoring, telemedicine, home care, etc., and all kinds of home functions are almost all-encompassing. However, the current situation is still relatively mature with the digital home application of multimedia entertainment, and it is also the primary aspect of the full development of various manufacturers.
Living room-centered digital home concept
Second wave of living room revolution
If the "family theater" trend of a few years ago was regarded as the "first wave of living room revolution", then "digital home (living room)" will become the second wave of revolution.
In the trend of the "family theater", the audio-visual equipment in the living room has been greatly upgraded, trying to create entertainment in the home as well as small cinemas. Traditional tape recorders have been replaced by DVD players and DVD recorders; CRT TVs have been replaced by large-size flat-panel TVs, plasma TVs, LCD TVs, and even larger-screen projectors; stereo speakers built into TVs, Switched to a multi-channel speaker that connects to the surround amplifier. If you add karaoke equipment, you can also have the function of KTV.
Next, the second wave of revolution that the “digital home†will drive will bring all kinds of highly digital multimedia content to the home theater audio and video equipment, and obtain the vast digital content and numbers through the connection of the network. Services, internal communication of family members' personal computers and various digital devices.
"Digital Multimedia" is the first key, and today's digital electronic technology nearly fully digitizes traditional media content. In terms of films, in addition to the digital DVDs in the family theater era, there are now digital video, streaming video on the Internet and other technologies. In terms of music, the popularity of MP3 has replaced the CD, and almost everyone has a portable digital player. In terms of photos, there are digital cameras that make photography easier, more convenient and faster.
"Network Link" is the second key. In the age of broadband, such as the popularity of modern Internet, modern people are almost inseparable from the Internet every day, becoming the fastest and most basic tool for collecting information and interpersonal communication. In the digital home, the network plays the role of communicating digital devices, sharing archive data, and connecting with the world.
More importantly, "digital multimedia" and "network link" are contemporary technologies that most people are familiar with and use freely, but the current applications are limited to personal computers. Providing a variety of multimedia applications or connecting to a network with a mainstream computer is only a basic basic. The only problem is that the computer is in a personal room and is harder to share with other family members.
Key technologies for digital home maturity
Therefore, the digital family wants to achieve the purpose of “drawing digital entertainment out of the individual study roomâ€, and put the multimedia digital content in the living room with the big screen and surround sound of the home theater. The fastest and most direct way is to put it in the living room. The previous computer, replacing the TV tuner, DVD player, etc., became the new core of the home theater.
Such an idea is not the case now. Manufacturers began to scream the slogan "Digital Home" a few years ago, but the overall application has been delayed. The low acceptance of the market has always been regarded as the main problem, but we believe that a large part of the problem is that the hardware and software cannot cooperate. So until the recent new hardware and software, it has brought more hope for the maturity of the digital home.
Power-saving low-heat high-performance CPU
As a living room computer, the first important component is the CPU. Earlier low-end CPUs were cheaper, but they were more difficult to load and require multimedia editing and decoding, and they didn't save power at all. While high-end dual-core CPUs (such as the Pentium-D) are efficient enough, they are expensive and consume a lot of power. The noise from the fans used for cooling is even more unbearable.
The recent development of new CPUs is not small. The new dual-core micro-architecture not only has higher performance, but also enhances multimedia computing capabilities, even for HD high-definition movies. Moreover, the CPU heat is reduced, which makes the fan volume smaller, which avoids noise interference when listening to music. In addition, the new CPU is more power efficient, and of course it is more suitable for long-term multimedia applications, which can save users a large amount of electricity.
High-capacity hard disk
The living room computer also plays the role of a multimedia storage center. In addition to having to accommodate the multimedia files of the whole family, recording TV programs requires a lot of storage space. Fortunately, the current hard disk price is getting lower and lower, the capacity is getting bigger and bigger, and it depends on the vertical recording technology, and there is still room for a significant increase in the capacity of the hard disk in the future.
The popularization of technologies such as external hard drives, external disk arrays (RAID), and e-SATA high-speed interfaces also facilitates flexible expansion of storage space. In addition, there are also emerging home NAS products, which can be used as a storage center with network connection to provide file servo function independently of the computer, and greatly enhance the flexibility of expansion and setting.
Digital home composition equipment
After talking about the concept, let us see what the actual devices that make up the digital home are. To build the most basic digital home, there are three things that must be indispensable: the living room computer + display device + network equipment.
--Living room computer--MCPC
Everything that builds a digital home will begin with a computer in the living room. But not just a computer, choose a computer that supports digital home functions, you can save a lot of self-DIY installation settings, and future compatibility will be "better."
In order to facilitate consumers to distinguish which products support the digital home, there is Viiv multimedia entertainment platform in the Intel camp, AMD Live is launched in the AMD camp! Both are paired with the Windows XP MCE operating system, so in addition to the different component specifications, the function is not too different, can be commonly known as MCPC (Media Center PC).

When purchasing such a computer, you need to pay special attention to the "TV card" accessory. The MCPC with TV card can select and pre-record programs through convenient program schedules. Some high-end models also have two built-in TV cards, which can record two programs at the same time. If the MCPC has fewer TV cards, the use will be quite limited.

In addition, there are some products that are not computers, which can replace the functions of some MCPCs. They will use the SOC integrated single-chip system as the computing core, with the Linux operating system to provide functional interfaces, such as TiVo we have introduced.

Display device - TV or projector
With the living room computer, you have to have a display device to play the picture. The general MCPC considers compatibility and usually provides a variety of analog and digital video terminals, so the most traditional CRT TVs can be connected with AV terminals or S terminals; high-end flat TVs may use color difference terminals; the latest digital TV , you can use DVI or HDMI two digital interfaces.
Traditional TV can also enter the digital home, but the resolution is...
In terms of resolution or screen size, if you are installing with an existing TV, if you plan to install a new TV, you should try to support the 1080p specification as much as possible within the budget, and choose a 16:9 ratio. Wide screen large size model. So in the upcoming HD era, it will not fall back to the popular.

In addition, if the home environment space permits, projectors capable of projecting larger screens are also available as "second" display devices. Because the projector needs to turn off the light, it is not suitable for watching TV every day. Therefore, you should keep a TV for different situations.

Network equipment - wired or wireless
One of the key points of the digital home is the network connection, so of course, it is necessary to install network equipment. Usually we need a Router-level broadband sharer to tap ADSL or Cable broadband to connect the living room computer to the personal computer of the member.
Wireless router supporting MIMO--Asus WL-500W
We recommend that the broadband sharer can choose to have built-in wireless AP function, and there are four or so LAN Port products at the same time, no matter whether it is to support wired or wireless network, it will not be a problem. In addition, there is also an advanced router with a built-in hard disk or an external hard disk that can provide NAS functions. In addition to centrally storing files, it can also construct a home website, FTP, photo album, etc., and has the convenience of multi-purpose.

Digital home matching equipment
More PCs, NBs: Many people now have more than one computer. The problem is not that there are not enough computers to connect, but how to let these computers share files and remote access. The current setting in MCPC is not simple enough.
TV signal: Whether it is to watch the fourth, digital TV or satellite TV, of course, you must first have a TV signal source. As long as the TV card has support, the fourth and digital TV signals can be connected to the MCPC and can be viewed with Media Center. Satellite TVs require an additional selector, which is cumbersome.
Multi-channel theater audio: Connect the MCPC to the digital integrated amplifier with digital fiber, and then connect to the 5.1 or 7.1 surround speakers to achieve true theater-level audio and video enjoyment.

Expand storage devices: If you frequently record TV shows, you will find that the hard disk space is running out. At this time, if you still can't bear to delete the previous video, you have to back up some of the content to the DVD, or add an external hard drive to expand the space. The current external hard disk interface is more common with USB and IEEE 1394. The new e-SATA specification can fully utilize the high-speed transmission of SATA hard disk, which is a higher-order choice.
NAS Network Storage Center: If you are afraid that the computer in the living room is too wasteful to be powered on for 24 hours, you can consider using a home NAS as a file storage center. All computers in the home can access the above data through the network. Some models are also available. For home use, FTP, photo albums, etc.

Extender: MCE supports remote operation of the device network through "Extender" and access to the MCPC in the living room. It seems that you have a second MCPC. One of the more popular examples is Microsoft's own game console, the Xbox 360.

WebCam, IP Cam: The digital home system with these digital cameras can develop more life applications. For example, two families can go out and chat together through the network video in their living room. For monitoring purposes, a line or wireless IP Cam can be installed at the required location for access control security monitoring, home care for children or the elderly.
More peripherals: Digital homes that claim to connect all home appliances, of course, for digital Walkman, PDA, DC, mobile phones, etc. MCPC can immediately synchronize or directly play the digital content on these devices, and can also have convenient wireless connection through WiFi, Bluetooth and other technologies, and more magical applications will occur one after another.
Conclusion
This digital home theme is based on conceptual explanations and outlines the equipment needed to construct a digital home. I hope to help you get a first look at the overall concept. In the next few digital meta-family series, we will also continue to look forward to the DIY architecture digital home, the practical strategies for providing various life applications, and the procurement guide for various digital devices.
