| 20080273858 | Video Trick Mode System - A method for producing an auxiliary video stream arranged for reverse trick mode playback from a video stream including a plurality of uni-directional predicted frames, the method including producing the auxiliary video stream by performing the following steps copying each uni-directional predicted frame included in the video stream into a memory, thereby producing a plurality of copied frames in the memory, replacing each one of the plurality of copied frames with one corresponding supplemental frame, thereby producing a plurality of corresponding supplemental frames, and producing a copy of the video stream arranged in reverse processing order, the producing a copy including replacing each frame which corresponds to one of the plurality of copied frames with the one corresponding supplemental frame from among the plurality of corresponding supplemental frames. Related methods and systems are also described. | 11-06-2008 |
| 20090100186 | SYSTEM FOR DATA STREAM PROCESSING - A method for processing a data stream including receiving a transport stream (TS), storing at least a portion of the TS, the at least a portion of the TS having a beginning and including a plurality of TS packets, determining, from among the plurality of TS packets, at least one TS packet including a candidate access point, storing in an index store a byte offset of the candidate access point; and storing in the index store a plurality of indications of byte offset, each byte offset being associated with an arrival time of a received TS packet. | 04-16-2009 |
| 20090178073 | Method and system for control of broadcast content access - A method for controlling access to content, the method comprising: receiving content in an area in which access to the content is blacked out, the content corresponding to a blacked out event; preventing display of the content at the time of receipt; recording the received content; and allowing access to the recorded content after a time criterion is met, wherein the time criterion comprises an elapse of a predetermined period of time measured from a specified one of the following: commencement of the blacked out event and termination of the blacked out event. | 07-09-2009 |
| 20090199231 | Time shifted interactive television - Methods and apparatus for managing, implementing and using interactive applications and content that are digitally recorded and viewed in real-time and/or a time-shifted moded are provided. The interactive applications may be associated with television programs or may be unrelated thereto, and may be transmitted together with television programs or separately therefrom. Interactive applications that are employed in a time-shifted mode can be matched to current conditions and interactive content may be updated to include current data. Users may view and manipulate highlights of television programs and receive alerts of occurrence of real-time events during viewing of recorded material. Additional manipulations of interactive applications and content are also enabled. Related apparatus and methods are also described. | 08-06-2009 |
| 20100278229 | System for random access to content - A method for accessing a desired point in time-synchronized data within a stream, the stream being associated with time information, the method including providing a desired presentation time associated with a desired point within a time-synchronized data stream, determining a stream access point, decoding the stream beginning at the stream access point, and assigning a time associated with the stream access point as a utilization time. Related apparatus and methods are also disclosed. | 11-04-2010 |
