Provided herein are apparatus and methods for improving transmission efficiency of video content for Wireless Fidelity (Wi-Fi). An apparatus for a Wi-Fi device comprises a Radio Frequency (RF) interface and processing circuitry coupled with the RF interface. The processing circuitry is to encode a Medium Access Control (MAC) frame, to carry video content to be transmitted to one or more other Wi-Fi devices connected with the Wi-Fi device; encapsulate the MAC frame into a physical (PHY) frame, the PHY frame is to include an additional byte in a high-efficiency signal-A (HE-SIG-A) field, to indicate whether the MAC frame is encoded as an original MAC frame including one Frame Check Sequence (FCS) or a video content specific MAC frame including more than one FCSs; and transmit the PHY frame, via the RF interface, to the one or more other Wi-Fi devices.
