20090044244 | Apparatuses and Methods for Scanning Digital and Analog Television Channels - Apparatuses and methods for scanning channels in a television signal receiver. The apparatuses generally include a first acquisition circuit, a second acquisition circuit, and a controller. The first acquisition circuit is generally configured to determine, during a first time period, whether a selected radio frequency channel has a first format and to produce a first acquisition indicator in response thereto. The second acquisition circuit is generally configured to determine, during a second time period overlapping the first time period, whether the selected radio frequency channel has a second format and to produce a second acquisition indicator in response thereto. The controller is generally configured to scan a plurality of radio frequency channels by operating the first acquisition circuit and the second acquisition circuit for each one of the plurality of radio frequency channels. Embodiments advantageously provides for faster scanning and acquisition of television signals in a mixed-format (e.g., analog and digital) television distribution environment. | 02-12-2009 |
20100027610 | EQUALIZER AND EQUALIZATION METHOD - An equalizer generates an equalized sample from a plurality of received samples in which a forward equalizer filters a received sample to generate a FE output. A feedback equalizer filters the equalized sample to generate a FBE output. An integrator adds the FE and FBE outputs to generate the equalized sample. The feedback equalizer comprises first and a second sub-filters. The first sub-filter has a first bit-width capability to generate a first FBE output from the equalized sample. The second sub-filter has a second bit-width capability to generate a second FBE output from the equalized sample. The first bit-width is higher than the second bit-width, and the first and second FBE outputs jointly organize the FBE output. | 02-04-2010 |
20150181154 | METHOD AND SYSTEM FOR PLAYING VIDEO - The present invention discloses a method for playing a video, which includes the following steps: a selected video is played on a first display unit through a video player. A corresponding script related to the selected video is received through a handheld electrical device. A currently playing time of the selected video is received through the handheld electrical device from the video player. Metadata, which is related to the corresponding script and has a plurality of time stamps, is played through a second display unit of the handheld electrical device according to the currently playing time. During a process that the selected video is played on the first display unit, the handheld electrical device is utilized to re-receive the currently playing time of the selected video from the video player at a preset time interval. | 06-25-2015 |
