Can you play 720p on composite cable?

Composite video signals are used with standard definition video. There is no composite encoding system for HD signals. As 720p, 1080i and 1080p are all HD signals, they cannot be carried on a composite signal.

Can lime effectively be used to decompose dead bodies"?

Yes, lime can be used to help decompose dead bodies by accelerating the process of decomposition.


What are the differences between the Fourier and Laplace transforms and how do they each contribute to the analysis of signals and systems?

The Fourier transform is used to analyze signals in the frequency domain, showing the signal's frequency components. It is mainly used for periodic signals. The Laplace transform, on the other hand, is used for analyzing signals in the complex frequency domain, showing both frequency and decay rates. It is more versatile and can handle non-periodic signals and systems with memory. Both transforms are essential tools in signal and system analysis, providing different perspectives and insights into the behavior of signals and systems.

What is the exact definition of Composite Video Signal?

A composite video signal is one in which several signals are combined. The signals are: Horizontal synchronising pulse Vertical synchronising pulse Luma signal (the brightness of the image) 2 chroma signals (the color information of the image) The signal is multiplexed so that image information is delivered between the sync signals. The luma signal is mixed with one of the chroma signals on one line and with the other chroma signal on the next line. The signal refreshes a complete frame by delivering odd numbered lines in the first field and all even numbered lines in the second field. Therefore, two fields are used to generate a complete frame. The use of two fields per frame was an early form of compression and allowed the frame rate to be fixed at 25 or 30 frames per second without a noticeable flicker appearing in the image. The color encoding system has three variants. North America uses NTSC encoding, Europe uses PAL while France chose a third system called SECAM. All color encoding systems use the composite signal in the same way but carry slightly different chroma signals. Composite signals are used only for standard definition signals. HD signals do not use encoded color signals and are always carried as three separate signals, whether in analog or digital form. Frame rates and line counts are not part of the composite signal definition but generally, NTSC encoded signals use 60Hz field rates with 480 visible lines (525 lines including lines that are not used for the image). PAL signals generally use a 50Hz field rate with 576 visible lines (625 lines in total including non-visible lines). SECAM signals are in line with PAL rates and line counts.

Can you use ps2 component cables through composite?

You can, but I'd suggest that it's used only for short runs, maybe up to 6 feet, max. The picture quality will probably suffer due to internal signal reflections, causing ghosting of the image or ssome smearing of the video, but it'll work.


Is composite biodegradable?

Composite materials can vary widely in their biodegradability depending on their components. Some composites, particularly those made from natural fibers and biodegradable resins, can break down over time in the environment. However, many composites, particularly those that include synthetic plastics or non-biodegradable materials, do not decompose easily and can contribute to environmental pollution. It's essential to evaluate the specific materials used in a composite to determine its biodegradability.


What would you say is the main difference between materials that decompose and those that don't?

Materials that decompose can be used to plant other foods. Materials that do not decompose have paper, peeling and left over foods in it.


What is the meaning of DVD Component In for a color tv and what will happen if a TV don't have that?

Component video signals are in fact three separate signals. One carries brightness information and the other two carry color information. It is the format used in broadcast environemnts and provides the best video quality. Please note that component is NOT an RGB signal, as used in VGA signals. Even if a DVD player has component output, it will also support composite signals, which use a single signal cable. The connection will be on an RCA or phono connector or perhaps on a scart connector in Europe. Most players will also have an S-video output as well as composite. Check that the television has either a composite input or an S-video input and the player should work without any problem. S-video is a better quality signal than composite and should be used if there is a choice between the two. All of the signals mentioned so far are analog. Most modern televisions and DVD players now have HDMI or DVI links. Although these are both interfaces designed to support high definition, they also operate at standard definitions. HDMI carries sound on the same cable and therefore provides a convenient and high quality interface.
