20090175355 | Method and Apparatus for Compressing Video Sequences - A method and apparatus for compressing a plurality of video sequences, is provided where each sequence has information that is common with other video sequences. The ensemble encodes the video sequences into an MPEG compliant transport stream using less predicted frame information than separately encoding each video sequence. One illustrative application involves efficiently encoding and transmitting a user interface such as a program guide, interactive program guide, electronic program guide, navigator and the like. The user interface is illustratively embodied in an interactive program guide (IPG). | 07-09-2009 |
20100146554 | Temporal Slice Persistence Method and Apparatus for Delivery of Interactive Program Guide - Techniques to efficiently deliver interactive program guide (IPG) to a number of terminals. Each IPG page can be decomposed into a guide portion that is specific to each IPG page and a background portion that is common for all IPG pages. The background portion can be further decomposed into a time-varying video portion and other static portions. One method includes receiving a viewer selection for imagery, where the imagery includes at least one intracoded slice and at least one predictively coded slice, and each of the intracoded and predictively codes slices are associated with respective bitstreams. Packets from the at least one bitstream corresponding to the at least one intracoded slice of the selected imagery are extracted, and packets from the at least one bitstream corresponding to the at least one predictively coded slice of the selected imagery are also extracted. The payload portions of the extracted packets are then arranged to form the selected imagery. | 06-10-2010 |
20100296574 | APPARATUS AND METHOD FOR COMBINING REALTIME AND NON-REALTIME ENCODED CONTENT - A terminal for decoding and presenting encoded realtime and non-realtime interactive program guide (IPG) content including a realtime video portion and a non-realtime guide graphics portion. The terminal includes a demodulator operative to receive and demodulate a modulated signal to provide a transport stream, and a transport demultiplexer coupled to the demodulator and operative to receive and process the transport stream to provide a sequence of transport packets re-timestamped to synchronize encoded realtime content and encoded non-realtime content included therein. At least one video decoder is coupled to the transport demultiplexer and operative to receive and decode the encoded realtime and non-realtime contents to recover the realtime and non-realtime contents for the user interface. | 11-25-2010 |
20110022961 | Interactive User Interface - A user interface for an interactive information distribution system comprising a graphics region, a video region and a mask/reveal layer. The user interface is generated in a head end of the system as a digital bitstream and transmitted to subscriber equipment for display. Operation of the user interface is facilitated by functions on both a local level with the subscriber equipment and on a system level within the head end. One embodiment of the user interface is an interactive program guide. | 01-27-2011 |
20110314500 | Method and System for Providing a Program Guide and Multiple Video Streams Using Slice-Based Encoding - Methods for slice-based encoding of program guides and user interfaces. The program guides include multiple video streams for picture-in-picture and other applications. A method for encoding the program guide includes encoding a first set of slices for each of a plurality of graphics pages; and encoding a second set of slices for each of a plurality of video streams. | 12-22-2011 |
20140137155 | SERVER-CENTRIC CUSTOMIZED INTERACTIVE PROGRAM GUIDE IN AN INTERACTIVE TELEVISION ENVIRONMENT - Techniques to create, generate, and deliver customized interactive program guide (custom-IPG). In one embodiment, selections indicative of a set of channels to be included in the custom-IPG are received. In response, one or more custom-IPG screens including the set of selected channels are rendered at a headend. Custom-IPG screens can be formed as subsets of the regular IPG screens, or as new screens. The rendered custom-IPG screens are provided from the head end to a set top terminal upon receiving a viewer request for the custom-IPG. Commands indicative of a particular location at which to overlay the custom-IPG screens may also be received, and the custom-IPG screens are re-rendered at the indicated location. Custom-IPG screens can be overlaid on a video sequence provided on a particular channel being viewed, used to carry regular program guide, or a channel independent of the channel used to carry regular programming and program guide. | 05-15-2014 |
20140189749 | Apparatus and Method for Combining Realtime and Non-Realtime Encoded Content - A terminal for decoding and presenting encoded realtime and non-realtime interactive program guide (IPG) content including a realtime video portion and a non-realtime guide graphics portion. The terminal includes a demodulator operative to receive and demodulate a modulated signal to provide a transport stream, and a transport demultiplexer coupled to the demodulator and operative to receive and process the transport stream to provide a sequence of transport packets re-timestamped to synchronize encoded realtime content and encoded non-realtime content included therein. At least one video decoder is coupled to the transport demultiplexer and operative to receive and decode the encoded realtime and non-realtime contents to recover the realtime and non-realtime contents for the user interface. | 07-03-2014 |

20120308942 | Oil burner, regulating device and regulating method therefor - A method for regulating a temperature of a combustion medium in a mixing zone of a burner and a method for regulating a burner, in particular an oil burner, a burner performance being modulated. A heating system including a burner, which includes a regulating device, and a regulating device for a burner, in particular an oil burner. The method/system is intended to provide as constant a temperature as possible in the mixing zone during the different operating modes and with changed burner performance. The combustion air flows through a first supply tract in a first operating mode and in adjustable proportions through the first and/or a second supply tract in a second operating mode, and the combustion air is supplied with heat via a heating element, which may be switched on and off, in the first supply tract, and with heat from a combustion zone in the second supply tract. | 12-06-2012 |
20130344447 | OIL PREMIX BURNER - An oil premix burner comprising: a combustion element; a burner surface on the outer lateral surface; a distribution chamber below the burner surface; a central oil injection device; a combustion air channel connected to a blower situated upstream as well as an air heat exchanger for the preheating of the combustion air in the area of the burner surface. In each case, the annular space formed between the inner tube and the outer tube of all the double tube elements opens out into an annular-shaped collecting chamber, and the preheated combustion air, starting from the collecting chamber, flows inwards via a swirl-generating device into the area around the oil injection device into the distribution chamber. | 12-26-2013 |

20110108422 | EX VIVO MULTI-DIMENSIONAL SYSTEM FOR THE SEPARATION AND ISOLATION OF CELLS, VESICLES, NANOPARTICLES AND BIOMARKERS - Devices and techniques are described that involve a combination of multidimensional electrokinetic, dielectrophoretic, electrophoretic and fluidic forces and effects for separating cells, nanovesicles, nanoparticulates and biomarkers (DNA, RNA, antibodies, proteins) in high conductance (ionic) strength biological samples and buffers. In disclosed embodiments, a combination of continuous and/or pulsed dielectrophoretic (DEP) forces, continuous and/or pulsed field DC electrophoretic forces, microelectrophoresis and controlled fluidics are utilized with arrays of electrodes. In particular, the use of chambered DEP devices and of a properly scaled relatively larger electrode array devices that combines fluid, electrophoretic and DEP forces enables both larger and/or clinically relevant volumes of blood, serum, plasma or other samples to be more directly, rapidly and efficiently analyzed. The invention enables the creation of “seamless” sample-to-answer diagnostic systems and devices. The devices and techniques described can also carry out the assisted self-assembly of molecules, polymers, nanocomponents and mesoscale entities into three dimensional higher order structures. | 05-12-2011 |
