Title (EN) AUDIO AND VIDEO PLAYBACK DEVICE AND AUDIO AND VIDEO PLAYBACK METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE LECTURE AUDIO ET VIDÉO
(ZH) 音视频播放设备和音视频播放方法
Abstract:
(EN) Provided in the embodiments of the present invention are an audio and video playback device and an audio and video playback method, the audio and video playback device comprising a system processor, a video processor, and a video format conversion bridge, the video processor respectively being coupled to the system processor and the video format conversion bridge; the video processor receives screen display menu data from the system processor and receives an external video signal from an external signal source, and superposes the screen display menu data and the external video signal or a main video signal selectively; after the superposed external video signal is received and the data format thereof is converted by means of the video format conversion bridge, the converted external video signal is transmitted to a display screen; the audio and video playback device is thus simultaneously provided with a high definition picture and is suitable for the execution of large-scale software functions, and the user experience and willingness to use the device are enhanced.
(FR) Des modes de réalisation de la présente invention concernent un dispositif de lecture audio et vidéo, ainsi qu'un procédé de lecture audio et vidéo. Le dispositif selon l'invention comprend un processeur système, un processeur vidéo et un pont de conversion de format vidéo, le processeur vidéo étant couplé respectivement au processeur système et au pont de conversion de format vidéo ; le processeur vidéo reçoit des données de menu d'affichage d'écran du processeur système et reçoit un signal vidéo externe provenant d'une source de signal externe, et superpose les données de menu d'affichage d'écran et le signal vidéo externe ou un signal vidéo principal de façon sélective ; après la réception du signal vidéo externe superposé et la conversion de son format de données au moyen du pont de conversion de format vidéo, le signal vidéo externe converti est transmis à un écran d'affichage ; le dispositif de lecture audio et vidéo est ainsi simultanément doté d'une image à haute définition et adapté à l'exécution de fonctions logicielles à grande échelle, et l'expérience de l'utilisateur ainsi que la propension de ce dernier à utiliser le dispositif sont améliorées.
(ZH) 本发明实施例提供一种音视频播放设备和音视频播放方法,该音视频播放设备包括系统处理器、视频处理器以及视频格式转换桥片,其中视频处理器分别耦接于系统处理器与视频格式转换桥片,视频处理器从系统处理器接收屏幕显示选单数据以及从外部信号源接收外部视频信号,并且将屏幕显示选单数据选择性的与外部视频信号或主视频信号进行叠加,然后通过视频格式转换桥片接收及转换叠加后的外部视频信号的数据格式,并且将转换后的外部视频信号传送至显示屏,让音视频播放设备兼具高清晰度画面以及适于执行大型软件的功能,而增进用户体验与使用意愿。
