A viewer who signs up for a high definition television entertainment package is outfitted with a high definition satellite receiver at no additional charge to the viewer.
The viewer subscribes to Dish Network programming and receives a satellite receiver in order to prevent non-subscribers from viewing the encrypted information and pirating the programming. The satellite receiver decrypts the programming and transmits the signal that the users television displays as an intelligible image. The programming is compressed in order for the satellites and the cable connecting the satellite dish to transmit the data which comprises the actual channels of programming available to the viewer with a paid subscription.
The DISH Network receiver is the component that decompresses the data received by the satellite. High definition television has a higher picture resolution with an aspect ratio of 16:9 which differs from standard television which has an aspect ratio of 4:3. In addition to the higher quality video image, high definition television incorporates a more comprehensive audio format. These factors cause high definition television to be more data intensive than regular television. In HDTVs uncompressed form, this type of programming can require up to ten times the bandwidth for transmission as standard television. The electromagnetic waves that carry Dish Networks programming are not restricted to any realistic bandwidth limitations, however, the transmitted programming experiences congestion when the data information is carried to the satellites and the cables connecting the satellite dish to the users receiver due to the physical limitations of these technologies. Because of this phenomenon, dish Networks programming is compressed into MPEG-2 format before it is transmitted to the satellites. High Definition television contains more data and is further compressed into MPEG-4 format. This discrepancy is the reason that a customer that subscribes for high definition TV service must use the specific Dish Network HDTV receiver in order to decompress the MPEG-4 programming in addition to the MPEG-2 programming. A viewer can watch both standard television (in MPEG-2 format) and high definition (MPEG-4 format) on a Dish Network HDTV receiver but not the converse configuration (viewing MPEG-4 on a receiver configured to decompress MPEG-2 only).
Standard television has 480 horizontal lines of resolution whereas high definition television has either 720 horizontal lines of resolution or 1,080 horizontal lines of resolution. Dish Networks high definition television satellite receivers configure all of these issues which enables the user to view the appropriate picture on the screen for the programming the user is watching.
DVR Recording functions are user-friendly and can be initiated by selecting a program from the Electronic Program Guide (EPG), by conducting a search for a particular program, or by setting manual timers. Because of the multiple tuners and output features, the viewer can be recording three different programs and watching two other recorded programs on two different televisions. Total recording time depends upon format but, generally it's 200 hours of SD and up to 30 hours of HD.
The interactive Electronic Program Guide is a huge benefit of subscribing to satellite television. It holds nine days worth of programming and can be used to set recording and other timers (auto tuning or reminder). An additional function is an on-screen caller-id for identifying phone calls, and further interactive features for news, sports info, and games. Finally, Video On Demand (VOD) is a recently added service/feature which allows the viewer to do exactly as the name suggests, watch videos when personally desired and not to be restricted by broadcasting time.
