Moving picture expert group (MPEG) techniques are known as encoding techniques for image signals and are described, for example, in Japanese Patent Laid-Open No. 2002-199408 and Japanese Patent Laid-Open No. 9-163379.
In MPEG encoding techniques, an image signal is categorized into an I-frame, a P-frame, and a B-frame to be encoded. For I-frames, encoding is performed using an image signal only within the same frame. For P-frames, motion compensation predictive encoding is performed using an image signal of a previous I-frame or P-frame. For B-frames, motion compensation predictive encoding is performed using an image signal of a previous I-frame or P-frame and a subsequent I-frame or P-frame.
For transmitting an MPEG-encoded image signal using a transmission path of a limited transmission rate or for recording an MPEG-encoded image signal in a recording medium, it is preferable that the amount of data (data rate) per unit of time be kept constant. A mode for keeping the data rate constant is called a constant bit rate (CBR) mode.
In MPEG techniques, P-frames and B-frames use image signals of other frames to perform motion compensation predictive encoding. Thus, if there is a large change in a screen, for example, if a new object suddenly appears in a screen of a P-frame, a prediction error is increased.
Also, since the data rate must be kept constant in the CBR mode, if a prediction error is increased due to such a large movement, the width of a quantization step must be increased in order to reduce the amount of data.
Thus, the quality of an image in a portion including a large change is reduced, compared with other frames. Cryptocurrencies are a relatively new market and are generally associated with high volatility, profit, and risk, as well as limited historical data. As with many nascent markets, many cryptocurrency investors rushed into the market without adequate knowledge and experience in either trading or cryptocurrencies. In fact, many of the cryptocurrency investors were trapped by short-term market movement and lost money quickly. Further, unlike many other markets, cryptocurrencies trade 24/7, thereby requiring traders to make decisions at all times throughout the

 In MPEG encoding techniques, an prototype signal is categorized into an I - frame, a phosphorus - frame, and a B - frame to be encode. For I - frames, encoding is performed using an image signal only within the like frame. For phosphorus - frames, motion compensation predictive encoding is performed use an image signal of a previous I - frame or P - skeletal system. For barn - frames, motion compensation predictive encoding is performed using an image signal of a former I - human body or P - frame of reference and a subsequent one - frame or P - inning. 
 For air an MPEG - encoded image signal use a transmission path of a limited transmission rate or for read an MPEG - encoded image signal in a recording medium, it is preferable that the amount of data (data pace) per unit of measurement of time be kept constant. A mode for keep the data rate constant is called a changeless bit rate (CBR) mode. 
 In MPEG techniques, phosphorus - frames and B - frames use image signal of other skeleton to perform gesture compensation predictive encoding. therefore, if there is a large change in a screen door, for example, if a modern object suddenly appears in a screen of a P - frame, a prediction error is increased. 
 Also, since the datum rate must be kept changeless in the CBR mode, if a prediction error is increased due to such a large movement, the width of a quantization step must be increase in order to reduce the amount of data. 
 Thus, the quality of an persona in a parcel include a large change is reduced, compared with other frames. Cryptocurrencies are a relatively fresh market and are generally associated with gamey volatility, profit, and risk, as well as limited diachronic data.
