摘要： A method and apparatus is provided that converts video content from a first format type into a second format type so that the video content can be viewed with other video content that has the second video format type. The method includes determining a first format of a first stream of video content (702) and determining a second format of a second stream of video content (704, 706). The method also includes converting (806, 808) the format of the second stream of video content into the format of the first stream and combining (812) the first stream of video content with the converted second stream of video content to form. In order to display the first and second video content streams the method decodes the combined first and converted second stream of video content using the first format.

摘要： In embodiments of broadcast content to HTTP client conversion, a client converter (118) receives video content (108) as an input (204) of broadcast content data streams from a content distribution system (102). The client converter can join a content data stream of the broadcast input, and convert the content data stream to unicast HTTP data, such as video content segments (124) that are buffered for communication to a client device (120) or to a media player (138) of a client device (134). An HTTP server (122) of the client converter can then communicate the unicast HTTP data to the client device or to the media player for playback of the video content.

摘要： A three-dimensional (3D) video encoder includes a first encoder, a second encoder, and a multiplexer. The first encoder is configured to encode a base view to form a first independently compressed video stream associated with video content. The second encoder is configured to encode a nonbase view to form a second independently compressed video stream associated with the video content. The multiplexer is configured to multiplex the first and second independently compressed video streams associated with the video content to form a transport stream. The transport stream is operable to be processed to render a 3D video using the base and nonbase views.

摘要： Data are received at a receiving device from a server, where the data are encoded into one of a plurality of different versions, each version having a different fidelity level. A data stream having a buffer with an initial maximum window size for buffering received data is requested from the server, wherein the data stream initially has a first fidelity level. The maximum window size is managed to prevent the current window size from falling below a threshold that might trigger an adjustment by the server in the fidelity level of the data stream sent by the server, unless and until the accumulation of data in the buffer due to a decrease in the present processing capabilities of the controller of the receiving device falls below a threshold of processing power necessary for processing the data stream at the higher fidelity level for more than a transitory period of time.

摘要： A content moving device which enables providing content stored on a first user device, such as a DVR, in a first format and resolution to be provided to a second user device, such as a portable media player (PMP) in a second format and resolution. The content moving device identifies content on the first user device as candidate content which may be desired by the PMP and assigns a priority level to the content. The content moving device transcodes the candidate content in order of highest priority first and lowest priority last. The content moving device may also use the priority level to manage deletion of the transcoded content from the storage on the content moving device. The lowest priority level content may be deleted first as storage space is needed.

摘要： In a method of encoding video content, bits of a first view and a second view of a three-dimensional (3D) video content are manipulated to occupy a first slice of video and a second slice of video, wherein a boundary is configured to be formed between the first and second slices. In addition, the bits of each of the first slice and the second slice are encoded separately from each other to form a first independently compressed video slice and a second independently compressed video slice. The first and second independently compressed video slices are then multiplexed to form at least one transport stream operable to be processed to render at least one of two-dimensional (2D) and 3D video.

摘要： A method for determining quantization parameters is provided. The method includes determining one or more first units of video content in a grouping of units and analyzing whether the one or more first units of video content within a region in the grouping of units have coefficients for the video content that are zero. The method then determines whether a quantization parameter for one or more second units of video content different from the one or more first units of video content is to be used to derive the quantization parameter for the one or more first units of video content. When the quantization parameter for the one or more second units of video content is to be used, the quantization parameter for the one or more first units of video content is derived from the quantization parameter for the one or more second units of video content.

摘要： Video data is received in 2D or 3D format from different channels as a user scrolls through an electronic guide. The video data may be displayed in a portion of the on screen display along with graphic and text associated with the EPG data. The received video data may be converted to a suitable format to be displayed with Electronic Program Guide (EPG). The video data may be converted from a 3D to a 2D format to be displayed with the EPG data. The video data may be converted from a 2D format to a 3D format, while the EPG data displays in a 2D format. The video data may be converted from one 3D format to another 3D format for display with the EPG data. The selection of converting the received video data can be based on a display format of a previously viewed channel prior to requesting the EPG to be displayed.
摘要翻译： 当用户滚动通过电子指南时，以不同频道的2D或3D格式接收视频数据。 视频数据可以显示在屏幕显示的一部分以及与EPG数据相关联的图形和文本中。 所接收的视频数据可以被转换成与电子节目指南（EPG）一起显示的适当格式。 视频数据可以从3D转换成2D格式以与EPG数据一起显示。 视频数据可以从2D格式转换成3D格式，而EPG数据以2D格式显示。 视频数据可以从一种3D格式转换成另一种3D格式，以便与EPG数据一起显示。 转换所接收的视频数据的选择可以基于在请求显示EPG之前先前观看的频道的显示格式。
