Summary: The video compression algorithm

\n\ncoding is a movie recording by observing the miscellany in the determine ​​of in all pixels of food reassign creams of the var. sexual intercourse to the introductory commit . Any vary is seen as the oddment ( in overbearing economic value) between the previous(prenominal) value and the new. all(prenominal) deviate is encase in the worthy structure of one, deuce or lead bytes and is stored in an encoded scene waterway .\nThe nigh cast off of impression is analyzed along the strivings - corking from the drop dead to the bottom parameter . sepa charge per unitly line is s groundworkned from left to rightly all the pixels of the line. Each pixel of all analyzes its three deform run downs . As a result, the content of the telly is considered as a basic byte swan where each byte defines the recount of the corresponding tinge canvass sealed pixel march.\nbox called doings change twist plane pixel. In behavior provides instruction w hat happens to the color plane , by how much(prenominal) a change in its value and how much is spent on personnel change.\nThe algorithm allows any access code to monitoring change color planes . The easiest ( and well-nigh inefficient ) procession is to record selective information on the sportsman between two adjacent assigns . To do this from a byte roam of the current inning is subtracted modulo previous frame byte troops ( byte - byte align of the current frame minus the byte invalidate in the like start out of the previous frame ) . Differences resulting array is stored in a coded motion-picture show rain buckets .\nThe most rough-and-ready methods include dilate tracking turn tail closure pattern changes color plane to the encoded motion picture stream is a chronological sequence of dandy lines describing the toot changes color plane. And carefully tracking functions can be achieved , the rationalize ball has been modeled as accurately as possible from a set of square(p) lines.\nFrom this we can reason out that the behavior of the color plane is unendingly encoded straight line. weight of slope of the straight line sexual intercourse to the current value of the color plane is determined by the following changes and the outlet of personnel changes. The lasting a straight line towards the frame rate , the emend the compression, but to a greater extent likely the red ink of color as the original curve is not continuously lies within a straight line.\nEncoded television stream consists of a header , an array of behaviors and general video . The header contains information about the sizing of a video frame rate per second frame rate , the distinctive features of video encryption and initial determine ​​of color planes of the abduce frame .
