摘要：A system transmits human interface data (HID) as ancillary data to a television

receiver over white space. Content on a user mobile device may be wirelessly displayedon an external display device. It may be desirable to have user interactions with themobile device (such as controls for video games) displayed on the external display devicein a manner that does not suffer from the latency of standard video being set to thedisplay device. The HID may be captured and processed separately from the video data.The HID may be formed into a transport stream for transmission over white space. TheHID may be included as ancillary data in the transport stream. Timestamps may be usedto coordinate the transmission of the HID as well as its processing when received by atelevision receiver.
