Abstract: Techniques described herein are directed to the inline switching of video and/or audio codecs for video and/or audio data. A first device encodes data that includes portion(s) that are encoded using a first codec and portion(s) that are encoded using a second codec. The encoder may further encode supplemental information in the data. The supplemental information is used by the decoder to determine a transition between the first and second portion(s). The decoder can thus anticipate the transition and properly switch the codec used to decode the data in real-time. Techniques described herein are also directed to the splicing of locally-stored content into content received from a remotely-located source. For example, targeted advertisements that are stored locally may be played back during commercial breaks of live content. The locally-stored targeted advertisements may replace the commercials provided via the remotely-located source.

Abstract translation: 本文描述的技术涉及用于视频和/或音频数据的视频和/或音频编解码器的在线切换。 第一设备对包括使用第一编解码器编码的部分和使用第二编解码器编码的部分的数据进行编码。 编码器可以进一步编码数据中的补充信息。 解码器使用补充信息来确定第一和第二部分之间的转变。 因此，解码器可以预期转换并且实时地适当地切换用于解码数据的编解码器。 本文描述的技术还涉及将本地存储的内容拼接到从远程位置的源接收的内容中。 例如，本地存储的定向广告可以在实况内容的商业中断期间播放。 本地存储的有针对性的广告可以替代通过远程位置的源提供的广告。
