Abstract:
1. A method comprising: receiving at an intermediate network device interposed in a network path between a source and a receiver, video optimized for a wired network link located between the source and the network device; determining at the intermediate network device if the receiver is a wireless device operating in a wireless network; and if the receiver is a wireless device, identifying at the intermediate network device, video parameters used by the source to optimize the video for transmission over the wired network link and determining if said video parameters are optimal for wireless transmission in the wireless network, optimizing the video for said wireless transmission if said video parameters are not optimal for wireless transmission, and transmitting the video to the receiver; if the receiver is not a wireless device, transmitting the video from the intermediate network device to the receiver in its received format; wherein optimizing comprises reformatting or re-encoding the video for transmission over the wireless network to add greater protection and quality of experience in the expectation that wireless data loss may occur.
