As satellite dishes became smaller and more affordable, most satellite signal providers adopted various forms of encryption in order to limit reception to certain groups (such as hotels, cable companies, or paid subscribers) or to specific political regions. Early encryption attempts such as Videocipher II were common targets for pirate decryption as dismayed viewers saw large amounts of formerly-unencrypted programming vanishing. Nowadays some free-to-air satellite content in the USA still remains, but many of the channels still in the clear are ethnic channels, local over-the-air TV stations, international broadcasters, religious programming, backfeeds of network programming destined to local TV stations or signals uplinked from mobile satellite trucks to provide live news and sports coverage.

The first encryption methods used for big-dish satellite systems used a hybrid approach; analogue video and digital encrypted audio. This approach was somewhat more secure, but not completely free of problems due to piracy of video signals.
Direct broadcast satellites and digital cable services, because of their digital format, are free to use more robust security measures such as the Data Encryption Standard (DES) or the RSA and IDEA digital encryption standards. When first introduced, digital DBS broadcasts were touted as being secure enough to put an end to piracy once and for all. Often these claims would be made in press releases.
Two-way communication has also been used by designers of proprietary digital cable TV equipment in order to make tampering more difficult or easier to detect. A scheme involving the use of a high-pass filter on the line to prevent two-way communication has been widely promoted by some unscrupulous businesses as a means of disabling communication of billing information for pay-per-view programming but this device is effectively worthless as a cable operator remains free to unsubscribe a digital set-top box if two-way communication has been lost. As a device intended to pass signals in one direction only, the line filters offer nothing that couldn't be done (with the same results) by an inexpensive signal booster - a simple one-way RF amplifier already widely available cheaply and readily for other purposes. Also, many such boxes will disallow access to pay-per-view content after a set number of programs are watched before the box can transmit this data to the headend, further reducing the usefulness of such a filter.
Along with modifying original cards, it is possible to use the information provided by the smart card to create an encryption emulator. This, in turn, can be programmed into a cable or satellite receiver's internal software, and offered for download on the internet as a firmware upgrade. This allows access to the encrypted channels by those who do not even own a smart card. In recent times, many underground forum websites dedicated to the hobby of satellite piracy and encryption emulated Free To Air (FTA) receivers have been set up, giving up-to-date information on satellite and cable piracy, including making available firmware downloads for receivers, and very detailed encryption system information available to the public.
In some countries such as Canada and many Caribbean nations (except for the Dominican Republic), the black market in satellite TV piracy is closely tied to the gray market activity of using direct broadcast satellite signals to watch broadcasts intended for one country in some other, adjacent country. Many smaller countries have no domestic DBS operations and therefore few or no legal restrictions on the use of decoders which capture foreign signals.
The grey market for US satellite receivers in Canada at one point was estimated to serve as many as several hundred thousand English-speaking Canadian households. Canadian authorities, acting under pressure from cable companies and domestic broadcasters, have made many attempts to prevent Canadians from subscribing to US direct-broadcast services such as AT&T's DirecTV and Echostar's Dish Network.
While litigation has gone as far as the Supreme Court of Canada, no judicial ruling has yet been made on whether such restrictions violate the safeguards of the Canadian Charter of Rights and Freedoms which are intended to protect freedom of expression and prevent linguistic or ethnic discrimination. Domestic satellite and cable providers have adopted a strategy of judicial delay in which their legal counsel will file an endless series of otherwise-useless motions before the courts to ensure that the proponents of the grey-market systems run out of money before the "Charter Challenge" issue is decided.[citation needed]
Bell Satellite TV (as Bell ExpressVu) was sued by Vidéotron, a Québécor-owned rival which operates cable television systems in major Québec markets. Québécor also owns TVA, a broadcaster. Bell's inferior security and failure to replace compromised smartcards in a timely fashion cost Vidéotron cable subscribers, as viewers could obtain the same content for free from satellite under the compromised Nagra1 system from 1999 to 2005; pirate decryption also deprived TVA's French language news channel LCN of a monthly 48/subscriber fee. The Superior Court of Quebec awarded $339,000 and $262,000 in damages/interest to Vidéotron and TVA Group in 2012. Québec's Appeal Court ruled these dollar amounts "erroneus" and increased them in 2015; despite an attempt to appeal to the Supreme Court of Canada, a final award of $141 million in damages and interest was upheld.[20]
Itis worth noting that you need to get this correct on three planes, the east andwest direction, the elevation and the skew adjustment on the LNB itself. Thisis the part that makes allowance for the deviation off due south. For example,Sky and Freesat both use the Astra 2 satellites at 28.2 degrees East off duesouth, because it is beaming the signals down to earth from an angle adjustmentmust be made at the satellite dish to make allowances for this and so the LNBitself can differentiate between horizontally and vertically polarised signals. If you are aligning to foreign satellites from the UK, here are some guides on French, Polish and Italian satellite reception.
If you have a spare satellite receiver to hand it might beworth disconnecting your existing satellite receiver and trying the spare one.You should also bear in mind that if you are receiving encrypted TV serviceslike Sky that you will not be able to receive these without a compatible boxand viewing card. This will only affect the encrypted TV services however, likeSky 1, Sky Sports etc but could still be used for the free unencrypted serviceslike BBC, ITV and to see whether your satellite dish is working.
Google Earth Pro on desktop is now free and available to download for Windows, macOS, Android and Linux. Explore worldwide satellite imagery and 3D buildings and terrain for hundreds of cities. Zoom to your house or anywhere else, then dive in for a 360 perspective with Street View.
If you need street navigation and turn by turn directions, Google Maps is the better choice. If you're looking to explore places from a bird's eye view, then you should download Google Earth. Both services share map information from the same source, but which is better will depend on the use you plan to give them.
VNC Connect is the latest version of our remote access software for personal and commercial use. It consists of a VNC Server app for the computer you want to control, which must be licensed, and a VNC Viewer app that you are free to download to all the devices you want to control from.
If you have a Peloton unit at home and pay the $44/month all-access membership, then you can download and use the app for free. But if you just want the app without the bike, it will set you back $12.99 a month.
Spectral land surface albedo is an important parameter for describing the radiative properties of the Earth. Accordingly it reflects the consequences of natural and human interactions, such as anthropogenic, meteorological, and phenological effects, on global and local climatological trends. Consequently, albedos are integral parts in a variety of research areas, such as general circulation models (GCMs), energy balance studies, modeling of land use and land use change, and biophysical, oceanographic, and meteorological studies. Recent production of land surface anisotropy, diffuse bihemispherical (white-sky) albedo and direct beam directional hemispherical (black-sky) albedo from observations acquired by the MODIS instruments aboard NASA's Terra and &la satellite platforms have provided researchers with unprecedented spatial, spectral, and temporal information on the land surface's radiative characteristics. Cloud cover, which curtails retrievals, and the presence of ephemeral and seasonal snow limit the snow-free data to approximately half the global land surfaces on an annual equal-angle basis. This precludes the MOD43B3 albedo products from being used in some remote sensing and ground-based applications, &mate models, and global change research projects.
