Met@box 2000 Functionality

The met@box 2000 was made to be the multimedia centre of the living room. It supports a huge variety of common media formats. Whether you want to watch or record TV or Video, Listen to CD Audio or MP3 files, surf the net or read and write emails, the met@box 2000 will completely revolutionise the way we use our televisions.

With new interactivity standards on the way the television will become a thoroughly new entertainment experience. In the past standards were not in place thus hindering the advance of interactive enhanced television. Direct marketing, games, electronic programme guides, surveys, ecommerce applications, and much more will accompany the media-rich content we receive through television networks giving the audience more choice, variety, and fun than ever before.

What is the main purpose of the met@box 2000?

Basically, television has stayed the same for a number of decades. Apart from changing from black and white to colour, and mono to stereo, the resolution and broadcast standards have been kept the way they were. However, the transmission technologies are moving from analogue to digital and bandwidth is becoming available for digital data services. A wide range of applications like games, interactive TV, internet-browsing, MP3 downloads, video conferencing, and voice over IP will make the TV exciting again.

A combination of analogue and digital services would help audiences to take part in a new era of entertainment. To enable the new technology a platform is needed which is flexible and modular to accommodate both analogue and digital formats as well as different types of high-speed internet access devices. For this purpose the met@box 2000 was defined.

Network connectivity

The met@box 2000 is capable of handling standard modems as well as cable modems and other high-speed connections. In order to facilitate flexibility there is a slot dedicated to handling access to the internet which can handle both present and future networks.

Video and audio

Various MPEG standards have been adopted as current media formats. MPEG-II is without doubt the digital Video format for broadcasting. The newest form of audio compression is MPEG Audio layer III. This gives virtually no loss in recording quality but allows 10 songs to be recorded in the space of just one in PCM format. Video and audio Standards are moving very quickly so this feature is modular in order to keep pace with technology.

TV Tuner

There are several standards for TV tuners. Apart from different international broadcasting standards there are also various forms of transmission. Satellite offers both digital and analogue services. Cable networks also offer both types. Terrestrial transmission is also set to offer digital services. Even though this feature is not user-replaceable it is a part which can be specified by the purchaser in the shop. The tuner also acts as the BOT receiver

The DVD Module

Met@box AG placed a great deal of emphasis on the modularity of digital video to ensure supporting tomorrow's video standards. This may sound trivial but the logic on the board must be self-supporting in order to be fully replaceable in the event of a change of technology in future years.

The module is a video socket-card which supports DVD through the ATA bus connection. The DVD processor is controlled by the host processor through a gateway interface.

The module also allows various configurations of the met@box 2000 to be decided on in the production process. A device without a hard-disk, DVD ROM drive, and DVD module could act as an entry-level STB.

Standards supported by the DVD module:

  • ISO 9600 CD ROM
  • CD Audio
  • Video CD
  • DVD Video (MPEG-II)
  • Compressed Audio Disc (MP3)
  • Custom Met@box format DVD (key-encrypted MPEG-4)
  • MPEG-1 and MPEG-4 streamed from hard-disk
  • MPEG-1 and MPEG-4 streamed from network (VoD)


The results from the module can be in either analogue or digital form. The data is then transported to the graphics processor for display in a window or full screen depending on the application. Under no circumstances will any decryption keys be stored in permanent memory. The DVD module is far more complex than a standard DVD player. The module will allow a very high-level relationship between the player and the host processor. This will give more interactivity and support for emerging standards. The custom Met@box DVD format will use this special feature to request encryption keys.

MPEG-4 Whilst today's digital video broadcasting uses MPEG-II because of its clarity of picture the MPEG-4 standard is coming of age. High quality video at lower bit-rates make MPEG-4 an ideal compression standard for networks and high density discs. MPEG-4 is also the first widely-accepted interactive video standard for multimedia applications with high quality video requirements. The DVD module will be able to exploit the MPEG-4 standard and still comply to MPEG-II and MPEG-I. The Met@box custom DVD format will also implement many of the advanced features of MPEG-4 to ensure an abundance of quality material which can either encrypted or not.

Software

There is no solution today which addresses all the needs of a versatile STB with home computer functionality. The met@box 2000 has a combination of operating systems to ensure that programs will be available for every conceivable television application.

First of all, the met@box 2000 has a real-time pre-emptive operating system kernel to allow constant access to time-critical devices like BOT or Modem. Secondly, the met@box 2000 has a Linux operating environment to add file system functionality and device compatibility. Thirdly, the met@box 2000 has a JAVA virtual machine (JVM) to run highly portable applets from the internet. Fourthly, the met@box 2000 will have the latest JAVATV API which runs on the JVM to enhance the TV experience with interactive applications like electronic programme guide (EPG) and interactive television viewing.

New standards in interactive television to be supported by the met@box 2000

ATVEF (Advanced Television Enhancement Forum)
ATVEF was primarily designed to add interactivity to analogue and digital set-top-boxes. The idea is to provide a common platform for developing applications and content so that authoring is easier for content providers. Part of the specification demands compliance with certain HTML 4.0 commands and TV HTML extensions. Other ATVEF functions include overlays, windowing, transparency, positioning of components, triggers, URLs, CSS, and scripts.

ISO 7816 Smartcard systems
The standard for most of the present smart card systems is ISO/IEC 7816-3. This is supported by Mastercard MultOS, JavaCARD from Sun, Windows Smartcard, and VisaOpen to name just a few. ISO 7816-3 means that the device must read and write, normally through a serial interface. It must be able to load operate and manage applications. It must protect access to data and manage cryptographic algorithms. Smartcards are starting to play an important role in Ecommerce applications.

EPG (electronic programme guide)
EPG is basically an interactive television magazine. EPG is well defined in the JavaTV API so that all television channels can be compliant to all set-top-boxes that use JavaTV's EPG API. The idea behind EPG is that the audience will find it easier to search for and find content in today's multi-channel environment. One other important function is the booking of films, series, and pay-per-view events by marking certain programmes listed in the EPG. HTML is the format of content that was chosen to simplify the authoring of EPG. Advanced EPG can also support recording to VCR or Hard-disk.

PIP( Picture-in-Picture)
The met@box 2000 is capable of showing HTML and another data source simultaneously. This means that it is possible to view television or DVD in a window whilst still taking part in an interactive session on the internet. PIP stands for "picture in picture". The met@box 2000 is also equipped to size and resize the window or show it in transparent or full-screen mode.

BOT (Broadcast Online TV)
BOT is not an established standard but as a carrier of data it can be implemented in a common standard such as ATVEF. BOT has a near to real-time character meaning that applications like real-time stock brokerage or weather or news data can be as close to real-time as possible. BOT is packaged in the horizontal Blank interleave of a standard TV signal. The met@box 2000 uses it to carry up to 850 MB of HTML data a day without incurring online costs.

Video Overlay
Video overlay allows the mixing of digital and analogue signals so that they can be viewed simultaneously. One of the most well-known application for this is the Weatherman in front of a weathermap on a blue screen. The met@box 2000 uses this technology in order to display fonts, graphics, or animations on top of the TV or to display TV in a window of the browser. Video titling also uses Video overlay.

 

The remote Control is designed to let computer illiterates use very few buttons to achieve maximum results. To keep the typing of emails easy a keyboard is hidden within the remote control case.

This concept is new and will help the elderly to get accustomed to a new generation of devices.

 

 

The case was developed to be able to integrate storage devices normally typical to PCs or similar devices. DVD and Hard-disks can be installed in this case without the ugliness of slots and bays.

The smart card and on/off switch are easily accessible on the front of the device. A LED Display shows valuable information to the user like URL, Status, DVD or CD Audio title, or track number. The big @ Lamp is designed to let the user know when in standby mode

Possible applications for the met@box 2000

The met@box 2000 is an allround device which alleviates the need for several boxes in the living room. If such a device was already on the market today it would revolutionise the way we purchase consumer electronic products. The advantages of such a system are first of all price reduction, secondly, space saving, and thirdly, ease of use. Only one remote control to operate more than 10 different devices.
