Abstract: A method of annotating stored media information may include outputting stored media information based on an associated index file and receiving an annotation request at a point in the index file. The method may also include receiving and storing annotation information associated with the annotation request. The index file may be modified at the point at which the annotation request was received to reference the stored annotation information.

Abstract: A system and method for a ratings-based electronic guide. One method includes generating a ratings-based electronic guide based on content, related guide data and a content ratings list, where the content ratings list may include the ratings of the content for one or more of a specified location and a specified timeframe.

Abstract: A system and method for a content-centric electronic guide. The method may include receiving content and related guide data at a device, receiving an indication of favorite content of one or more viewers at the device and generating, by the device, a content-centric electronic guide based on the content, the related guide data and the indication of favorite content.

Abstract: A system and method for a content history-based electronic guide. One method includes tracking content accessed by a viewer; updating a history buffer based on the accessed content; and generating a content history-based electronic guide based on content, related guide data and the history buffer.

Abstract: According to some embodiments, content filtering is provided for a digital audio signal.

Abstract: A method and system for allowing time-shifted access to multiple programs or channels at the same time. A resource manager receives a request to change to a first channel. As a first personal video recorder (PVR) engine writes a media stream of the first channel to a first circular buffer, a playback engine reads the media stream of the first channel from the first circular buffer and sends the media stream to a display. The playback engine discontinues the reading of the media stream of the first channel once the resource manager receives a request to change to a second channel. Here, the first PVR engine continues to write the media stream of the first channel. A second PVR engine writes a media stream of the second channel to a second circular buffer while the playback engine reads the media stream of the second channel from the second circular buffer and sends the read media stream to the display.

Abstract: A method of program restoration may include outputting a first stream of media information until a triggering event and outputting a second stream of media information after the triggering event. The method may include monitoring the first stream of media information for one or more characteristics that reflect a change in the first stream of media information. The second stream of media information may be ceased and the first stream of media information may be output upon detection of the one or more characteristics of the first stream of media information.

Abstract: A method of annotating stored media information may include outputting stored media information based on an associated index file and receiving an annotation request at a point in the index file. The method may also include receiving and storing annotation information associated with the annotation request. The index file may be modified at the point at which the annotation request was received to reference the stored annotation information.

Abstract: A variety of different languages and formats can be displayed based on closed caption or other types of encoded text data. In one embodiment the invention includes receiving a video signal with encoded text data, decoding the encoded text data, translating the decoded text data, and combining the translated text data with a video portion of the video signal for display.
