| 20100058385 | System and Method for Detecting Closed Captioning and Creating a Closed Captioning Electronic Programming Guide - A set-top box device includes a detector module and an electronic programming guide module. The detector module is configured to detect a closed captioning flag in a video stream, and to cache electronic programming guide information for the video stream if the video stream includes the closed captioning flag. The detector module is further configured to create a closed captioning electronic programming guide including the electronic programming guide information. The electronic programming guide module is in communication with the detector module, and is configured to output the closed captioning electronic programming guide. | 03-04-2010 |
| 20100058420 | APPARATUS AND METHOD FOR MANAGING DIGITAL TELEVISION OPERATIONS - A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to monitor spectral characteristics of a target channel, a first channel and a second channel, where the target channel is of a digital terrestrial television system, where the first channel is an upper adjacent channel to the target channel, and where the second channel is a lower adjacent channel to the target channel. The controller is adapted to generate an emission mask based on the monitored spectral characteristics and detect interference between the target channel and at least one of the first and second channels based at least in part on the emission mask. Other embodiments are disclosed. | 03-04-2010 |
