Abstract: A method of coding and transmission of a 1080p or other higher resolution picture using a lower resolution differential signal overlay on top of a lower resolution existing video signal. The method may be useful for television service providers or other video related application providers in that the use of the lower resolution signals may allow the providers to utilize existing capabilities while providing a higher resolution picture.

Abstract: A method of facilitating transport of partially encrypted video is disclosed. The method re-packetizes or otherwise de-concatenates packets carrying the partially encrypted video into packets where all the video in each packet is either encrypted or unencrypted. The re-packetized video packets may include data that identifies whether the packet is carrying encrypted or unencrypted video.

Abstract: The scene is illuminated by light pulses at higher intensities at predetermined times than at times between the predetermined times. Images of the scene are captured at the predetermined times to provide a sequence of anchor frames in a stream of images, and images of the scene are captured at times between said predetermined times to provide non-anchor frames in the stream. The anchor and non-anchor frames are then compressed and processed to produce video with greater compression and reduced noise artifacts. The scene is illuminated by light pulses with wavelengths outside the visible range. Upon sensing motion, the scene is illuminated by light pulses to provide video in the visible wavelength range. The scene is illuminated by a sequence of light pulses of different wavelengths when motion is detected in the scene. Different wavelength images of the scene are combined to provide higher resolution colored images without color filtering.

Abstract: The present system for preventing the removal of advertising from digital television bitstreams detects the various advertising-specific factors, including: the time-wise predictability of advertisements, anomalies in the bitstream caused by the advertisement insertion process, and differences in the characteristics of advertisements versus the digital media content, then eliminates these characteristics from the digital media content bitstream. By eliminating the advertising-specific characteristics, there are no identifiable discontinuities in the digital media content bitstream that can be used to locate advertisements and therefore enable their removal from the digital media content bitstream.

Abstract: Disclosed is a system for allowing on-demand delivery of data, such as MPEG-2 compressed video data, to a subscriber from a content server. The system utilizes a managed IP network that is coupled to the one or more content servers that allows the content servers to deliver data such as video, audio, and textual data with a guaranteed quality of service that is at least as good as broadcast quality service. The managed IP network is connected to a head end or other local cable service provider where video is delivered locally to subscribers. The IP transport data is translated to MPEG transport data, multiplexed onto an MPEG transport system, digitally modulated onto an rf carrier and up-converted to a specific frequency channel. The signal is then applied to the cable for delivery to the subscriber. Upstream signaling occurs through a set top box or computer that is connected to the cable and subsequently to a digital modulator/demodulator and ISP to a managed IP network 66.
