    • A method for accelerating channel changes from a previous channel to a new channel in a video decoding device is proposed. A salient idea is to monitor the time intervals between channel change events so as to detect when a user is looking forward quickly browsing a set of TV channels. The disclosed method comprises at least two operation modes : a normal operation mode and a burst operation mode. In case the time between two consecutive channel change events is below a first value, the disclosed method comprises operating the channel change into a burst operation mode, wherein operating the channel change in a burst operation mode comprises only a subset of the features comprised in operating the channel change in a normal operation mode.
    • 提出了一种用于在视频解码设备中加速从先前信道到新信道的信道改变的方法。 一个突出的想法是监视频道切换事件之间的时间间隔,以便检测用户何时快速浏览一组电视频道。 所公开的方法包括至少两种操作模式:正常操作模式和突发操作模式。 在两个连续的信道改变事件之间的时间低于第一值的情况下,所公开的方法包括将信道改变操作为突发操作模式,其中以突发操作模式操作信道改变仅包括操作中包括的特征的子集 频道在正常运行模式下改变。
