20090097572 | USING BLACK DETECTION TO IMPROVE VIDEO SPLICING - In one embodiment, a network device analyzes an encoded video stream using black detection before splicing video into the encoded video stream. When black data is detected, the network device determines whether insertion of a black intra frame with the spliced video will improve viewing upon decoding. The network device may also determine whether a splicing boundary indication included in the encoded video stream is accurate based on an observed transition between the detected black data and other data, and compensate the video splice accordingly. | 04-16-2009 |
20090193454 | RESTAMPING TRANSPORT STREAMS TO AVOID VERTICAL ROLLS - In one embodiment, a network device analyzes an encoded stream to identify a timing value included in a packet before a splice point. Next, the device determines a difference between identified timing value and a timing value included in a packet of the encoded segment to be spliced. In conjunction with splicing, the network device formats timing values of packets according to the determined difference, which improves play out of the spliced stream. | 07-30-2009 |
20090313652 | AD SPLICING USING RE-QUANTIZATION VARIANTS - In one embodiment an apparatus for splicing an ad into a data stream includes an ad segmenter, an ad variant generator coupled to the ad segmenter, and an ad variant selector coupled to the ad variant generator. The ad segmenter designates end portions, including beginning and ending portions, of the ad and designates an intermediate portion between the end portions. The ad variant generator generates a plurality of variants of at least one end portion. Each variant corresponds to a unique bit-rate. The ad variant selector selects at least one variant for splicing into the data stream based on a buffer level of a data stream buffer. | 12-17-2009 |
20090320084 | PROVIDING PROGRAM RESTART FUNCTIONALITY IN A DIGITAL VIDEO NETWORK - A technique for providing program restart functionality in a digital video network involves receiving requests from different end-user devices to restart a program and servicing the program restart requests from the different end-user devices via a single broadcast stream. In an embodiment, program restart requests that are received within an established time interval, referred to as an aggregation interval, are serviced by the same broadcast stream. Additionally, during the aggregation interval and before the program restart begins, personalized content can be provided to the end-user devices via, for example, unicasting. Once the aggregation interval is over, all of the unicast streams are switched over to the same broadcast stream and the program broadcast is restarted. In an embodiment, a switch buffer is provided just before the restarted broadcast stream in order to ensure a smooth transition from each of the multiple unicast streams to the restarted broadcast stream. | 12-24-2009 |
20100129056 | Optimizing Ad Insertion By Removing Low Information Frames - Techniques are provided to perform seamless or non-seamless ad insertion using a low-complexity process. Delay is introduced into a transport stream to prevent decoder buffer overflow. Delay buildup in the transport stream is reduced by removing pre-identified redundant or near redundant frames. Pre-identification of frames for removal reduces the processing required at the splice points, while maintaining a minimum overall delay in the transport stream. | 05-27-2010 |
20110030001 | MINIMIZING BLACK VIDEO SEGMENTS DURING AD INSERTION - Black video segments in a video playlist may be minimized. Black detection may be utilized by a network device to identify true starting point and a true ending point of a video asset which includes black video segments in the playlist. Locations associated with the true starting and ending points may be recorded in metadata associated with the video asset. New black video segments may be added at the beginning and at the end of the playlist. Playback of the playlist may then be initiated to play the video asset only between the recorded location associated with the true starting point and the recorded location associated with the true ending point at the network device thereby minimizing the black video segments in the video asset. | 02-03-2011 |
