Abstract:
1. A method for transmitting video information to a remote video receiver, the method comprising: receiving, by a video transmission device, a request for a unit of video information from the remote video receiver; determining a first transmission rate based, at least in part, on a real-time determination of available communication bandwidth between the video transmission device and the remote video receiver; for a first time period after receiving the request, transmitting a first portion of the unit of video information at the first transmission rate, wherein first program clock reference (PCR) information for the first portion of the unit of video information is modified based, at least in part, on the real-time determination of available communication bandwidth and in accordance with the first transmission rate that is faster than a typical steady-state transmission rate for the unit of video information, and wherein the first time period is determined according to a target latency and an estimated buffer size of the remote video receiver; and for a second time period after the first time period, transmitting a second portion of the unit of video information at the typical steady-state transmission rate for the unit of video information, wherein the second portion of the unit of video information comprises second PCR information, and wherein the first PCR information is different than the second PCR information.
