What is Analog Video Signature?
535203
A relatively low cost, easy to operate video signature comparator and a corresponding method by which a known signature is visually compared to a sample signature to determine whether both signatures were made by the same individual. The signator comparator has particular application to forgery detection or to applications for verifying the authenticity of a signature. An electronic circuit is disclosed which displays video signals that are representative of the known and sample signatures. The circuit enhances video image density variations through extreme contrast and brightness adjustment and forces the lighter regions of each signature to white, such that only the dark stroke lines (indicative of those regions having the greatest density where the maker applied the most pressure) are displayed on video monitor. By visually comparing the characteristic density/pressure variations of the known signature to the sample, an observer can more accurately determine whether both signatures originated from the same maker.

Good day:\n\nCircular buffer is very important to store analog data before transfering to digital format. Circular buffer is effective to swicth to many devices simultaneously. Intel webiste provide lots of DSP information!\n\nThank you, bye!

Successive approximation A/D's work similar to a binary search algorithm.  The result can be very accurate if the A/D is designed correctly and the rate of the analog signal is relatively slow compared to the clock of the A/D, or a sample and hold block is used.  \nhere is an example of the operation (for this example a 4bit and that the input voltage is 1.2V):\n1.  using a DAC apply 1000 as a reference the  "1" is the test bit (say 1000 =1V)\n2.  Compare analog signal to this reference (result true) therefore the test bit is kept\n3.  Now apply the next test bit and the kept bit 1100 (the one in the 4's place is the new test bit and the one in the 8's place is the kept bit 1100= 1.5V)\n4.  Compare analog signal to this reference (result is false 1.2V <1.5V) therefore test bit is not kept\n5.  Now apply the next test bit and the kept bit 1010 (the one in the 2's place is the new test bit and the "10" in the 8,4's place is the kept bits 1010= 1.25V)\n6. Compare analog signal to this reference (result is false 1.2V <1.25V) therefore test bit is not kept.\n7. Now apply the next test bit and the kept bit 1001 (the one in the 1's place is the new test bit and the "100" in the 8,4,2's place is the kept bits 1001= 1.125V)\n8. Compare analog signal to this reference (result is true 1.2V >1.125V) therefore test bit is kept.\nResult is 1001\n\nHope this helps

Pretty sure yes. If anything, digital would be easier to spy on than analog.

Discrete Signal :\nObtained by sampling the analog signal at disctrete instants of time. However the magnitude of the discrete signals is same as that of the analog signal at that point in time. (Discrete only in time)\n\nDigital Signal :\nWhen the magnitude of the discrete signal is quantized to the the nearest integer, we get a digital signal. (Which is both discrete in magnitude & time)\n\nExample:\nSay, after sampling the analog signal, we get discrete signal as below\nx[0] = 0\nx[1] = 0.9\nx[2] = 1.8\nx[3] = 2.6\nx[4] = 2.1\nx[5] = 1.8 ....\n\nWhen you want to digitize this signal, you pass it through the ADC & the output would be as below.\nx[0] = 0\nx[1] = 1\nx[2] = 2\nx[3] = 3\nx[4] = 2\nx[5] = 2...\n\nThe above output depends upon the resolution of the ADC .\nMore the resolution, less the quantization error.\n\nI hope i answered your question.

Beta Max, I wanted one of those so bad. It was a good thing while they had both on the market. Beta had no macro-code readers, where VHS did. But, if you copied a video from VHS to Beta the Beta had no idea what it was so your copy was intact. No need for a macro-decoder. Great way to pirate rentals when you had little kids that watched a lot of Disney Movies. They were so friggin' expensive. Yeah, I know, I didn't set a good example. :-{\nOOPS, I am rambling. Life did pass me by. I figured that one out when my sister gave birth to twins on the 7th. I looked at these precious boys in the incubator and I said "Grandma's here!" All six of my grandchildren are older than they are.\nYeah, I know, I am a redneck, too.

AGP-Video card is the hardware board, supports to monitor device. Without AGP there is no out device for monitor.\n\nMore you can saw by picture based examples on below mentioned sites.

Hi there,\n\nMy recommendation is you can use Xilisoft Video Converter from http://www.xilisoft.com\n\nIt can convert multiple format (3GP, MOV, RM, AVI, MPG, etc)\n\nHope this information helpful\n\nCheers

"MPEG-7 is a multimedia content description standard. Thus, it is not a standard which deals with the actual encoding of moving pictures and audio, like MPEG-1, MPEG-2 and MPEG-4. It uses XML to store metadata, and can be attached to timecode in order to tag particular events, or synchronise lyrics to a song, for example."\nwikipidia \n\nIt is more of a time based tagging system. it is not a compression format.\n\n"MPEG-7 goes beyond the domain of audiovisual coding and focuses on efficient search and retrieval, filtering and semantic description of content." \n\nthis system can be used with audio, video and (audio with video)\n\nWhy you and me don't use it:\nthe fact that it is not all that useful to the average person.

Well i'm not sure specificially but my guess is your looking for some kind of video controller thing?  You might try a search at digikey.com for such a thing.  Also if you wanted the exercise you could use a state machine and some sram to output the correct signals.  An easier way might be to make a high speed DAC device that constantly plays the same pice of sram at a really high frequency then use software to write the correct NTSC signal.  kind of like a really fast sound card.  If you have some old isa video cards see if one has a DIP ramdac, then use a torch to carefully desolder it.    voila, instant analog front end for the project.  some even have a palette ram built right in?\n\nThe best place i've found for datasheets is http://alldatasheet.com/
