DTH for Software Downloads and Updates

Here is an example how i feel a DTH portal can interleave with interactive optical/wireless networks on land.

Let us assume Simtel has a DTH Channel. They broadcast MS updates from 10.00 AM to 10.30 AM. Linux updates at 11.00AM and Mac at 9.00 AM. All updates, some repetitive in gzip format and a advance xml feed indicating and enabling parsing of content on a digital device.

DTH for Software Downloads and Updates

From 1.00 PM to 5.00 PM is subscriber time. "Your favorite software is 'played' at these times". A user can use his phone or tablet to request a media. paid or free. All software will be broadcast at the time slot. With a xml feed/sitemap.

The user transfers the software from dth box to his computer using usb/lan. If he has been mailed dual layer decrypt keys he will be able to unzip the paid software. Else he can look thru the formatted/presented xml for any free software/media he would like to use.

DTH software providers can monetize using software developers to publicize their demo versions. Other firms from computers to toothbrush providers can give a "Media Promotion Pack" with wallpapers/freeware/video/audio/presentations and discounted/free offers.

Auxiliary Software Media DTH Download Box - Reduce Net Congestion

# Either you connect the USB of this Download-Box to Router to make a media server for your Netbooks & Tablets or plug it to your Desktop PC.

# This has a Tiny LCD Touch Screen, Key in the URL & Press Get, Wait. Media ready beep will come in a few secs. Satellite Delays don't matter.

# Invent something like Satellite Software/Media Download DTH Service - Small dish on Roof, A Stand alone Box with One Tera Byte HDD and USB.

DTT an interweave of WiMax and DTH

DTT - Direct To Tablet is a Technology, That is required in the communication Infrastructure, both for wireless and wireline networking. At Least till Optic Fibers Reach Every home.

If the Satellite Broadcasting Technology and RF Wireless Semiconductor Technology, advances fast. It may be Possible for DTT as a small module in the Tablet. This is TV on Tablet with Interactivity, as we have TCP/IP as well on Wi-Fi. This method does not load the TCP/IP infrastructure with HD Videos or Audio.

The other way is Intermesh WiMax with DTH to make Interactive TV on Tablet. The HD Media is requested by a Net Protocol, then it is got form Sattelite on Local DTH and comes to Tablet over WiMax. This way a HD Video need not travel a long distance, around the globe, causing traffic jams.

DTT an interweave of WiMax and DTH

I am sure, still nobody got me, or what i am talking of, but its is pleasant that way. Here is an image i had done a couple of years back. Try incremental levitation of the thought process, then you shall perceive a Tux on the Clouds.

Directly or Indirectly it is Tux who has made tablets possible in most all of the tablets you see today. They have made it happen. - In fact all are, some admit, some do not.

Wireless Home Automation and Application Server

The PC has much Evolved, From XT to AT, then from 286 to 586, the evolutionary trend continues. The Speed: GHz, Space: GB and Software: Linux-XP, have grown rapidly. The other vital things Interface, Networking and Power Consumption moved a bit slower. So some suggestions on the New Desktop for Small Office and Home Standard, that is crucial in the present computing scenario.

Enterprise Level Hardware and Software can be extrapolated from this idea for a SOHO. An Enterprise is like a SOHO Cluster. One big Homogeneous Entity is unstable and unreliable. When small varied, self-dependent entities collaborate to form an Enterprise, it is a Cluster of SOHOs, which is a Reliable and Resilient Entity.

Wireless Home Automation and Application Server
From Nomadic Computing

A Green solution could be New Desktop Computing Standard - The quiescent losses in this is only the wifi server cube, which can serve 6 tablets or UMPC. So if 6-12 people are using computers, many desktops need not be on. Tablets, Laptops and Notebooks consume less power and run on batteries. Thin Custom Notebook and Tablet Clients can use one OpenOffice on the WiFi Application Server cube

SOHO Desktop Standard
  • The Desktop Home Computer is the Wireless Router, Power Server.
  • SMPS Power Supply runs Both on 230V-110V AC and 12-24 V DC.
  • Home Wifi Computer, Application and Web Server is just a Cube.
  • Wireless Networked Peripherals, Printers, Drives, Viewers, Inputs.
  • Desktop Wifi Server networks 6 Handhelds and 12 peripherals.
  • Wireless Ethernet LCD Monitor-Keyboard for System Admin.

Semtech Corporation - Analog and Mixed Signal

Semiconductor Solutions for a wide range of Applications, from Networking & Communications and Consumer Electronics like Smartphones, Digital Camera, HDTV and Devices like Netbooks and Set Top Box. They also manufacture High Rel Discrete Semiconductors.

Semtech Corporation - Analog and Mixed Signal

The Communication Chips are used in Wireless LAN Modems, Satellite Communication, Cellular Infrastructure, Optical Transport and Datacenters.

The SX1243 is an ultra-low-cost, fully integrated FSK or OOK transmitter suitable for operation between 310 and 450 MHz, 860 and 870 MHz, as well as 902 and 928 MHz.

Semtech SX1243
It contains a frequency synthesizer which is a fractional-N sigma-delta PLL. For frequency modulation (FSK), the modulation is made inside the PLL bandwidth. For amplitude modulation (OOK), the modulation is performed by turning on and off the output PA.

The frequency reference used by the PLL is generated by a 22, 24 or 26 MHz crystal oscillator, depending on the frequency band of interest.

The Power Amplifier (PA), connected to the RFOUT pin, can deliver 0 dBm or +10 dBm in a 50 Ω load. Each of these two output powers need a specific matching network when efficiency needs to be optimized.

Facts of EMI and RFI from the Inside

Electromagnetic interference (or EMI, also called radio-frequency interference or RFI when in radio frequency) is disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.
Electromagnetic interference Wiki

Vertical polarized VHF- UHF biconical antenna

Vertical polarized VHF- UHF biconical antenna
170 – 1100 MHz with omni directional H-plane pattern

Who would know better about Radio Frequency Interference and ElectroMagnetic Interference more than the Hams or Amateur Radio Community.

If they have to communicate effectively using limited resources, they have to deal with EMI/RFI effectively, While they build their equipment or combat Noise from other Machines and Installations nearby.

EMI RFI Mains Filters

This problem needs more practical involvement and experimentation to learn, compared to learning something like Digital Electronics.

Equipment and Electricals like SMPS, AC/DC Drives, Motors, Solenoids and CFL Lamps are to be built/reinforced for low EMI/RFI emission/radiation.

Sensitive Medical Equipment like ECG or even a Aircraft can be seriously affected by Noise.
