A method for processing a packet-based scrambled stream, the method including receiving a plurality of scrambled packets in a packet stream, descrambling any of the scrambled packets, and transmitting a modified packet stream including at least one of the descrambled packets and at least one of the scrambled packets. Related apparatus and methods are also described.

Scrambled packet stream processing

This invention discloses a method for displaying advertisements transmitted to a user unit, the method includes receiving, at the user unit, at least one advertisement tagged with a delay tag indicating whether display of the at least one advertisement can be delayed and only if the delay tag allows delaying display of the at least one advertisement, storing the at least one advertisement at the user unit, retrieving the at least one advertisement and displaying the at least one advertisement. A billing system for reporting a commercial broadcast to a multiplicity of users is also disclosed.

Advertisements in an end-user controlled playback environment

A method for switching from playing a first compressed data segment to playing a second compressed recorded data segment, the method including playing an uncompressed copy of a start of the second compressed recorded data segment upon switching from playing the first compressed data segment, decoding the second compressed recorded data segment from a preceding random access point, the preceding random access point preceding, in the second compressed recorded data segment, a point at which playing is to be switched to the second compressed recorded data segment, stopping the decoding of the second compressed recorded data segment when reaching a point beyond a point currently being played in the uncompressed copy, and switching to playing the second compressed recorded data segment when playing the uncompressed copy of a start of the second compressed recorded data segment reaches the point at which the decoding of the second compressed recorded data segment was stopped. Related apparatus and methods are also provided.

Splicing system

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.

Method and system for control of broadcast content access

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.

System for data stream processing

A method for controlling access to content, including preventing access to content that corresponds to a blacked out event, until at least one of a time criterion and payment criterion is met. Related methods and apparatus are also disclosed.

A method for performing a computation task in a secure processor removably operatively associated with a host including a memory external to the secure processor. The method includes computing a portion of the task in the secure processor, obtaining a setting representation of settings of processing components of the secure processor at the end of the computing step, transmitting the setting representation to the external memory, retrieving the setting representation from the external memory, providing the setting representation to the secure processor, and resuming computation of the task in the secure processor by employing the setting representation.
