    Abstract: Methods and systems for pre-conditioning a video stream are provided herein. For example, an apparatus comprising a memory and one or more processors configured to execute instructions stored in the memory are provided. The instructions: identify packets of a first bitstream in a transport stream, such first bitstream corresponding to a base layer; identify packets of a second bitstream in the transport stream, such second bitstream corresponding to an enhancement layer; identify an initial packet corresponding to an ith picture in the first bitstream; identify an initial packet corresponding to the ith picture in the second bitstream; and reorder packets in the transport stream such that the initial packet corresponding to the ith picture in the second bitstream occurs after the initial packet corresponding to the ith picture in the first bitstream.

    Abstract: A system for displaying electronic program guide information about a plurality of video items on a screen, the system including a display module to display a plurality of pages layering into the screen, each of the pages including a plurality of graphical panels associated with the video items, and a user input module to receive a user input to turn at least one of the pages such that the at least one page is peeled away from other ones of the pages in order to bring the graphical panels of the at least one page in or out of view, wherein the display module is operative to show the turning of the at least one page bringing the at least one page in or out of view. Related apparatus and methods are also described.

    Abstract: A method for facilitating multiple recordings via a single tuner includes isolating data packets associated with recording candidate media assets from at least two broadcast data streams, generating at least one broadcast recording data stream from a subset of the isolated data packets, broadcasting the at least one broadcast recording data stream in parallel with the at least two broadcast data streams, where the broadcast recording data stream is broadcast via at least one dedicated broadcast “recording” device, and the at least two broadcast data streams are broadcast via other broadcast devices, storing remaining data packets not included in the isolated data packets in broadband data segments, and transmitting the broadband data segments via an IP connection to facilitate reassembly of partially recorded the media assets, where the partially recorded media assets were recorded from the broadcast recording stream. Related methods and apparatus are also disclosed.

    Abstract translation: 一种用于通过单个调谐器促进多次记录的方法包括将与至少两个广播数据流中记录候选媒体资产相关联的数据分组隔离，从孤立数据分组的子集生成至少一个广播记录数据流，将至少一个 广播记录数据流与至少两个广播数据流并行，其中广播记录数据流经由至少一个专用广播“记录”设备广播，并且至少两个广播数据流通过其他广播设备广播，存储 不包括在宽带数据段中的孤立数据分组中的剩余数据分组，以及经由IP连接发送宽带数据段，以便于部分记录的媒体资产的重新组合，其中从广播记录流记录部分记录的媒体资产。 还公开了相关方法和装置。

    Abstract: Methods and systems for processing a video stream are disclosed. A first tier value may be assigned to each of a plurality of SHRAP pictures in a first video stream. A reference tier value may be assigned to pictures in the first video stream that may be used as reference pictures. A plurality of discard tier values may be assigned to pictures in the first video stream that may be discarded during trick mode operations and do not depend on other pictures assigned one of the plurality of discard tier values. A trick mode operation may then be performed, wherein the presentation of pictures in the first video stream is dependent upon assignment of tier values.
