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 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.
