Abstract: A video system such as a television signal receiver includes a touch screen that may be suitable for larger image screens. According to an exemplary embodiment, the video system includes a screen having first and second sides, wherein a depression of the screen on the first side produces an image detectable on the second side. At least one projector is disposed on the second side of the screen and projects a first video signal onto the screen. At least one camera is disposed on the second side of the screen and detects the image. A processor determines a location of the depression according to the detected image.

Abstract: A method for selecting antenna configurations in a satellite receiving system, the method comprising: selecting antenna configurations using a first mode of operation wherein frequency shift keying (“FSK”) of a frequency is implemented, or a second mode of operation wherein a DC level is implemented, and adaptively controlling a capacitor to condition a signal while the second mode is in use and removing the effects of the capacitor while the first mode is in use.

Abstract: A receiver, such as an HDTV receiver or a Personal Video Recorder (PVR), includes a plurality of tuners. Each tuner is adapted to receive television signals (RF1,RF2) comprising a plurality of channels and communicate the received television signals to a processor. A channel search or autoprogramming routine is disclosed for the detection of channels in the television signal wherein each tuner simultaneously tunes and interrogates a different channel in order to expedite the search. If a signal is not detected on a channel, that channel may be tuned and interrogated by a second tuner. A list is compiled of all the channels that contain a television signal to aid the viewer's selection.

Abstract: A method for enabling access to digital rights managed (DRM) content from a server to a portable playback device using a device that functions as a proxy for enabling communication between the server and the portable playback device. The method provides for establishing a connection with a device capable of operating as a gateway device for passing data between the portable playback device and the server, requesting that the device establish a connection with the server and operate as a proxy for enabling data exchange between the portable playback device and the server, sending to the server, upon establishing the connection with the server via the device operating as a proxy, data indicating DRM solutions supported by the portable playback device, and a list comprising requested DRM content to be downloaded to the portable playback device, and receiving from the server, via the device operating as a proxy, the requested DRM content and DRM rules associated with the received content.

Abstract: The invention relates to spatially scalable encoding and decoding processes using a method for deriving coding information. More particularly, it relates to a method for deriving coding information used to encode high resolution images from coding information used to encode low resolution images when the ratio between high resolution and low resolution images dimensions is a multiple of 3/2. The method mainly comprises the following steps: deriving a block coding mode for each 8×8 blocks of a prediction macroblock MBi_pred from the macroblock coding mode of the associated base layer macroblocks on the basis of the macroblock class of MBi and an the basis of the position of the 8×8 block within MBi_pred; deriving a macroblock coding mode for MBi_pred from the coding modes of the associated base layer macroblocks; and deriving motion information for each macroblock MBi_pred from the motion information of the associated base layer macroblocks.
