Abstract: Methods, systems, and apparatuses are provided for enabling three-dimensional video and additional graphics to be displayed together without interference. A media content signal is received. The media content signal includes graphics overlay data representative of a graphics overlay, first image data representative of a first image, and second image data representative of a second image. The first and second images are representative of three-dimensional content. An interference is detected between the graphics overlay and the three-dimensional content in a three-dimensional view volume. At least one of the graphics overlay data, the first image data, or the second image data is modified to cause the graphics overlay and the three-dimensional content to be non-interfering. The non-interfering graphics overlay and three-dimensional content are enabled to be viewed by a viewer based on the modified graphics overlay data, first image data, and/or second image data.

Abstract: Methods and apparatus for switching between a live video decoding and a recorded playback in a digital video and recording system. A received video data stream is transmitted to a first-in first-out video decoder buffer without first looping the video data stream through a playback buffer. The video data stream is transmitted from the video decoder buffer to a video decoder. If a “pause” command is received, the video data stream is transmitted to a first-in first-out playback buffer, while continuing to transmit the video data stream to the video decoder buffer. Transmission of the video data stream to the video decoder buffer is halted when the video decoder buffer fills up. The last byte of the video data stream that was transmitted to the video decoder buffer is marked. If a “play” command is received, the video data stored in the video decoder buffer is transmitted to the video decoder. The video data stored in the playback buffer is transmitted to the video decoder buffer starting at a point immediately after the data element that was marked previously.
Abstract translation: 用于在实时视频解码和数字视频和记录系统中的记录回放之间进行切换的方法和装置。 接收到的视频数据流被发送到先进先出的视频解码器缓冲器，而不用先通过重放缓冲器循环视频数据流。 视频数据流从视频解码器缓冲器发送到视频解码器。 如果接收到“暂停”命令，则将视频数据流发送到先进先出播放缓冲器，同时继续将视频数据流发送到视频解码器缓冲器。 当视频解码器缓冲器填满时，将视频数据流传输到视频解码器缓冲器。 发送到视频解码器缓冲器的视频数据流的最后一个字节被标记。 如果接收到“播放”命令，则将存储在视频解码器缓冲器中的视频数据发送到视频解码器。 存储在回放缓冲器中的视频数据从紧接在之前标记的数据元素之后的点开始被发送到视频解码器缓冲器。
