Methods, systems, and apparatus, including medium-encoded computer program products for transmitting digital media streams. In one aspect, a computer-implemented method includes identifying and transmitting a sequence of frames in a digital video transmission, the sequence of frames comprising an initial frame and subsequent frames corresponding to the initial frame, the subsequent frames comprising data that incrementally updates the initial frame, and initiating a new transmission of the sequence of frames to a new device after sending one of the subsequent frames in the digital transmission, the initiating comprising generating information to cause the new device to inhibit presenting the new transmission until after frames between and including the initial frame and the one of the subsequent frames have been received by the new device, and transmitting, to the new device, the information and the frames between and including the initial frame and the one of the subsequent frames.
