Abstract: This document describes systems, methods, devices, and other techniques for determining media items to insert in a media stream. A first media client can play a primary media stream that is multicast to various media clients including the first media client and other media clients. The first media client identifies a start of a primary programming timeslot in the primary media stream, and in response, obtains and stores a secondary media item. After storing the secondary media item at the first media client, the first media client detects an insertion signal in the primary media stream that indicates a secondary programming timeslot is about to begin in the primary media stream. The first media client can then play the secondary media item in place of the primary media stream during the secondary programming timeslot.

Abstract: A video delivery system alters information (such as time stamp information) associated with one or more frames of a first compressed video file to allow for accurate rendering of frames within the first compressed video file prior to a transition to a second compressed video file. For example, a time stamp of a particular frame of a compressed video file is altered prior to transmission of the particular frame by a video transmission system such that the altered time stamp indicates a time that has already passed. The particular frame can be decoded by a display system that receives the particular frame so that information included in the particular frame can be used in rendering of subsequently received frames. The display system can bypass display of the particular frame due to the altered time stamp.
