摘要： A method and apparatus is described to reduce delay when changing channels in a television environment. The method may comprise receiving a plurality of television channels from a remote content provider wherein each channel includes channel information required to display the channel. At least one channel of the plurality of channels may be identified as a stored channel and channel information of the at least one stored channel may be stored in storage (e.g. in a circular buffer). Thereafter, upon selection of the stored channel, the stored channel information is accessed for display. In an example embodiment, the storage may be updated to maintain a most recently received I-frame and subsequent MPEG signals of the stored channel. Accordingly, when changing channels it may not be necessary to wait for the next I-frame to display a newly selected channel.
摘要翻译：描述了在电视环境中改变频道时减少延迟的方法和装置。该方法可以包括从远程内容提供商接收多个电视频道，其中每个频道包括显示频道所需的频道信息。多个信道中的至少一个信道可以被识别为存储的信道，并且至少一个存储的信道的信道信息可以存储在存储器中（例如，在循环缓冲器中）。此后，在选择所存储的频道后，存储所存储的频道信息以进行显示。在示例实施例中，可以更新存储以维持最近接收的存储信道的I帧和后续MPEG信号。因此，当改变频道时，可能不需要等待下一个I帧来显示新选择的频道。
