Abstract: Methods and systems for compressing video content are presented. The methods and systems include analyzing a sequence of media frames stored in the memory device and calculating a displacement level of each of the media frames. The displacement level indicates how different each of the media frames is to a previous media frame. The sequence of media frames is divided into a plurality of cuts where each cut ends at a media frame having a substantially high displacement level. Frames to be removed from the sequence of media frames are identified in each cut based upon the frame's displacement level. The identified frames are then removed.

Abstract: A system and method for stitching separately encoded MPEG video fragments, each representing a different rectangular area of the screen together into one single full-screen MPEG encoded video fragment.

Abstract: Systems and methods for push-based dynamic bandwidth allocation deliver addressable, advertising content in a digital network. Bandwidth is allocated on a push basis in response to receiving a trigger from a content distribution stream. The trigger contains data indicating an addressable break. A portion of bandwidth is then allocated to an addressable content stream based on the data of the trigger. The addressable content stream is then streamed to a receiver during the addressable break and the receiver is tuned from the broadcast stream to the addressable content stream for the duration of the addressable break. The additional bandwidth is de-allocated at the end of the addressable break.

Abstract: In accordance with the present invention, systems and methods that allow a television broadcast facility or a headend to insert in-band messages, where the inserted message allow receivers to switch to, insert, or otherwise show addressable advertisements to its viewers.

Abstract: The invention relates to a method for packaging media and data for transmission over a broadband communications network link for display at a terminal destination. Features of the method included creating desired media segments for transmission to the terminal destination and for creating targeting information, for example in whole or in part in the form of metadata, for transmission to the terminal destination. Other features include packaging the created media segments and the created targeting information in a single package and unpacking the single package for display of the targeted media at the terminal destination.

Abstract: A method of preparing data streams to facilitate seamless switching between such streams by a switching device to produce an output data stream without any switching artifacts. Bi-directional switching between any plurality of data streams is supported. The data streams are divided into segments, wherein the segments include synchronized starting points and end points. The data rate is increased before an end point of a segment, to create switch gaps between the segments. Increasing the data rate can include increasing a bandwidth of the plurality of data streams, for example by multiplexing, or compressing the data. The present invention can be used, for example, with MPEG or AC-3 encoded audio and MPEG encoded video segments that are multiplexed into MPEG-2 transport streams. Also included are specific methods for preparing MPEG video streams and multiplexing MPEG video with MPEG or AC-3 audio streams to allow a receiver to create seamless transitions between individually encoded segments.

Abstract: A system and method for masking/reducing the switch time from an analog or digital television channel to another digital television channel and back. Various optimizations which may be used individually or in combination to minimize the potential disruption to the viewer. This optimization is especially important when the channel switch is made automatically by the receiver, such as the case where the presentation of one television program is temporarily continued on another channel.
