A method is provided for facilitating error recovery of media stream packets in an access node. The method comprises storing a plurality of data transmission units of a media stream in a buffer of an access node, receiving a request for retransmission of at least one designated data transmission unit for reception by a designated subscriber media decoder apparatus, accessing the at least one designated data transmission unit within the buffer in response to receiving the request for retransmission and transmitting the at least one designated data transmission unit from the access node for reception by the designated subscriber media decoder apparatus in response to successfully accessing the at least one designated data transmission unit.

A method is provided for enabling rapid media stream channel changes in conjunction with increasing network resource utilization efficiency. A media stream is multicast for reception by a plurality of requesting decoders. The media stream includes packets containing groups of pictures (GOPs), which are stored in a buffer of an access node. At least a portion of the packets are unicast from the access node for reception by a new requesting decoder in response to receiving from the new requesting decoder a request for reception designating a media stream identifier corresponding to the media stream. Thereafter, the media stream is multicast to the new decoder after bringing packet transmission of the unicast media stream into alignment with packet transmission of the multicast media stream.

Video signal processing apparatus and methods are disclosed. An access termination terminates an access communication link that operatively couples a video service customer site to a communication network in which communication signals comprising video signals are distributed to video service customer sites. A video signal processor is co-located with the access termination and is operable to receive communication signals from the access termination, to extract a video signal from the received communication signals, and to output the extracted video signal for transfer to a display system at the video service customer site. Control signals may be received by the video signal processor from the display system over the same connection used to transfer video signals to the display system, or through a different connection such as a wireless connection. Video functions including video recording and other functions normally associated with set top video decoders may also be supported.

Video display capabilities for use in the home continue to evolve. A method is described including receiving a video signal in a first format, determining at least one parameter associated with the signal and a display device, converting the signal to a signal in a second format based on the signal and display device parameters, and converting the second signal to a display signal based on the display device parameter. An apparatus is described including an input stream processor that decodes and separates a received signal, a controller that determines at least one characteristic of the signal and a display device, a video signal processor circuit that converts the signal to a second signal based on the characteristics and further converts the second signal to an output signal based on a characteristic of the display device, and an interface circuit that provides the output signal to the display device.

A system and method for searching content and user interface for presenting results of the search are provided, wherein visual elements representing the content are distributed in three dimensions on a display, with the various axes representing criteria that relate to a central starting point of the search and the proximity to the central point indicating the degree of relevance. The outer bounds of the display contain a large amount of varied material of various types to allow a user to select content of a different type, with the content at the periphery of the display being essentially random and representing little or no link to the starting point of the search. Any displayed element may be selected, as a source for a next level search, in which case content relationships will be re-drawn, with the selected content used as the center point for a next level search.

Automatic determination of the complexity associated with converting image content from 2-dimensions to 3-dimensions commences by first determining how many different scenes exist within the image content. Each scene then undergoes analysis to determine its complexity based on the motion, texture and occlusion within the scene. The scene complexities are added to the scene transition complexity and the total gets weighted to yield an overall indication of the complexity of converting of image content from 2-dimensions to 3-dimensions.

A method and apparatus for changing the recording of digital content are provided. The method (300) includes receiving (310) a data stream, recording (320) the stream, receiving (330) a notification identifying a change in at least a portion of the data stream, and outputting (370) a subset of the recorded data stream based on the notification. The apparatus (200) includes a receiver (202) that receives a data stream, a storage device (212) that records the stream, a controller (214) that creates a subset of the recorded stream based on a notification received by the signal receiver and identifying a change in at least a portion of the data stream, the notification received separate from the data stream, and a display interface (218) that outputs the subset of the recorded stream.
