Title (EN) METHOD AND SYSTEM FOR IMPROVING SMOOTHNESS OF DISPLAY OF IMAGE
(FR) PROCÉDÉ ET SYSTÈME PERMETTANT D'AMÉLIORER LA NETTETÉ DE L'AFFICHAGE D'UNE IMAGE
(ZH) 一种提高图像流畅度的方法及系统
Abstract:
(EN) Disclosed is a method for improving smoothness of display of an image, comprising: detecting a current transmission frame rate of image data; and dynamically adjusting, according to the current transmission frame rate of the image data, data storing and reading rates in dual threads. The present invention employs a dual-thread technique, in which a thread a is used to receive and store network data, and a thread b is used to decode and display an image. When a CPU has poor performance, image decoding in the thread b becomes slower, but reception of network data in the thread a is less affected, thereby avoiding occurrence of network packet loss. Moreover, the present invention detects a current transmission frame rate of image data and dynamically adjusts, according to the transmission frame rate of the image data, data storing and reading rates in dual threads, thereby improving smoothness of display of an image, reducing lag time, effectively solving problems of screen abnormality, long lag times and poor smoothness, and enhancing stability and compatibility of a system.
(FR) L'invention concerne un procédé pour améliorer la netteté d'affichage d'une image, comprenant les étapes consistant : à détecter une fréquence de trame de transmission actuelle de données d'image ; et à régler dynamiquement, en fonction de la vitesse de trame de transmission actuelle des données d'image, des vitesses de stockage et de lecture de données dans des fils doubles. La présente invention utilise une technique à double fil, dans laquelle un fil a est utilisé pour recevoir et stocker des données de réseau, et un filb est utilisé pour décoder et afficher une image. Lorsqu'une CPU a une performance médiocre, le décodage d'image dans le fil b devient plus lent, mais la réception de données de réseau dans le fil a est moins affectée, ce qui permet d'éviter l'apparition d'une perte de paquet de réseau. De plus, la présente invention détecte une fréquence de trame de transmission actuelle de données d'image et règle dynamiquement, en fonction de la fréquence de trame de transmission des données d'image, des vitesses de stockage et de lecture de données dans des fils doubles, ce qui améliore la régularité de l'affichage d'une image, réduit le temps de latence, résout efficacement les problèmes d'anomalie d'écran, de temps de latence longs et de netteté médiocre, et améliore la stabilité et la compatibilité d'un système.
(ZH) 本发明公开一种提高图像流畅度的方法,包括检测当前的图像数据发送帧率,双线程中的数据存储及读取速率根据当前图像数据发送帧率动态调节。本发明利用双线程技术,线程a用于网络数据接收存储。线程b用于图像解码显示。当CPU性能较低时,只会导致线程b图像解码较慢,但是对线程a的网络接收影响较小,不会引起网络丢包情况的发生。同时本发明检测当前图像数据发送帧率,根据图像数据发送帧率动态调节双线程中数据存储及读取速率,能够提升画面显示的流畅度、降低延时,有效地解决了图像花屏、延时加深及流畅度降低的问题,增强了系统的稳定性和兼容性。
