In one embodiment, a method for ransomware-aware file backup is implemented on a computing device and includes: backing up a target population of files from a target file location in a backup transaction, computing a backup delta score for the backup transaction, where the computing comprises comparing backup data from the backup transaction with backup data from a previous backup transaction, determining whether the computer backup delta score exceeds a pre-defined threshold, and upon the computed backup delta score exceeding the pre-defined threshold: determining that the backup transaction is indicative of a ransomware infection, and performing at least one counter-measure in response to the ransomware infection.

Intelligent backup system

A system comprising a decoder to receive an encoded video stream including video frames including reference and non-reference frames, and decode the reference frames, a processor to receive a request from an end-user rendering device requiring a first reference frame as part of decoding the encoded video stream of the first channel from the middle of a group of pictures of the encoded video stream, wherein a second reference frame is a reference frame for the first reference frame in the received encoded video stream, an encoder to encode the decoded first reference frame yielding a re-encoded first reference frame so that decoding the re-encoded first reference frame is not dependent upon the second reference frame, and a transmitter to transmit the re-encoded first reference frame to the end-user rendering device. Related apparatus and methods are also described.

Mid-GOP fast channel-change

A fast channel change (FFC) system including a tuner arrangement to receive at least one transport stream including an aggregated video service (AVS) and TV channels, each video frame of the AVS including some video data of each channel, a demultiplexer arrangement to demultiplex a first channel and the AVS, a FCC buffer to buffer the video frames of the AVS, a decoder arrangement to decode the first channel, a controller to instruct the decoder arrangement to switch from decoding the first channel to decoding the AVS from the FCC buffer, and a graphic engine to extract the video data of a second channel from the AVS yielding a full-screen video, and output the full-screen video to a display device, wherein the controller is operative to instruct the decoder arrangement to switch from decoding the AVS to decoding the second channel. Related apparatus and methods are also described.

Fast channel change via a mosaic channel

A device including a module to receive a stream including an insertion content item and first timecodes, a module to record the stream, a module to receive a live stream including a timeslot and second and third timecodes, a clock to provide a clock reading updated based on at least some of the third timecodes, a module to retrieve the recorded stream so that the insertion content item can be at least partially rendered during at least part of the timeslot, a module to calculate a desired timecode of the first timecodes from which to start rendering the recorded stream for output at real-time speed based one of the first timecodes, second timecodes, and third timecodes or the clock reading, and a module to render the recorded stream for output at real-time speed from the desired timecode. Related apparatus and methods are also described.

Splicing system

A system for switching from a first () to a second () audio/video sequence, the second sequence () including a splice point time stamp (), the system including a disk () to store the first sequence (), a receiver to receive the second sequence as live audio/video, a demultiplexer arrangement () to demultiplex at least some of the first sequence () from the disk () and the second sequence () from the receiver, demultiplex the first sequence fast enough so that the demultiplexing of the second sequence () can commence a number of frames prior to the splice point time stamp (), a buffer () to receive for storage from the demultiplexer arrangement (), the demultiplexed audio/video of the first sequence () and at least part of the second sequence (), and a decoder () to decode the demultiplexed audio/video stored in the buffer () including decoding the first sequence () and then the second sequence () from the splice point time stamp (). Related apparatus and methods are also described.

A Headend system including a video codec to encode a video sequence yielding an encoded video sequence having video packets, a multiplexer, a signal generator to receive a notification of a splice point, analyze at least some of the encoded video packets based on the notification in order to find a random-access-point-packet, the random-access-point being a point from which to start decoding the encoded video sequence by the rendering device so that the video sequence may be rendered for output from the splice point, create a timing signal estimating a location of the random-access-point-packet in the encoded video sequence, and output the timing signal to the multiplexer or transmission equipment. Related apparatus and methods are also described.
