    摘要: A format converter for converting an input signal having a specified format to a digital signal of a pre-existing format, and for converting the digital signal back to the input signal automatically, loads an active data portion of the input signal into an input first-in/first-out (FIFO) buffer at a first data rate and reads the active data portion together with dummy filler samples from the FIFO at a second data rate as the digital signal. The number, location and/or values of the filler samples identify the specified format. In reverse the filler samples are stripped from the digital signal and the resulting active samples are loaded into an output FIFO at the second data rate. The stripped filler samples are used to determine the specified format of the original source of the data signal, and the active samples are read from the output FIFO at the first data rate in the specified format to reproduce the input signal.

    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.
