Provided in the embodiments of the present disclosure is a video transmission device. In the video transmission device, a video transceiving unit has two functions of receiving a video and sending a video, and a wireless communication unit can implement transceiving of video data in a wireless manner, such that the video transmission device can be multipurpose, i.e., the video transmission device can be used as both a wireless video-transmission transmitting device and a wireless video-transmission receiving device, so as to adapt to different scenarios. In addition, the video transmission device can further be integrated with a display unit, allowing the video transmission device to function as a monitor regardless of whether same is used as the transmitting device or the receiving device, thereby facilitating a user in watching, anytime and anywhere, a video that is sent or received by the video transmission device, which is highly flexible and convenient.

An apparatus for processing a serialised stream of video data includes a receiver configured to receive the serialised stream of video data, which includes a plurality of video frames, each video frame including a plurality of frame lines, at least one frame line including a group of active pixels and one or more blanking pixels, a memory configured to buffer the serialised stream of video data until all of the active pixels of a frame line have been buffered, one or more processors configured to, for each group of active pixels of a frame line, generate a data structure including the group of active pixels and a frame line position indicator and omitting at least one blanking pixel, and a transmitter configured to intermittently onwardly transmit the data structures by pausing transmission after each data structure has been transmitted until a next data structure is ready for transmission.
