Wireless receiving apparatus, data processing module, and data processing method, for receiving video image

A data processor comprising:

• a cyclic redundancy check (CRC) calculator configured to determine whether an error occurs in each of a plurality of sub-streams received from a plurality of wireless receiving apparatuses;
• a stream merger configured to, in response to determining that an error does not occur in any of the plurality of sub-streams, merge the plurality of sub-streams to generate a video frame;
• and
• a main controller configured to, in response to determining that an error does not occur in any of the plurality of sub-streams and a reception of the plurality of sub-streams constituting the video frame is completed within a total transmission period, transmit the video frame to a display that is electrically connected to the wireless receiving apparatus, and in response to determining that an error occurs in at least one of the plurality of sub-streams or the reception of the plurality of sub-streams constituting the video frame is not completed within the total transmission period, transmit an immediately-preceding video frame to the display.

A video reconstructing method of a wireless receiving apparatus, the method comprising:

• receiving a plurality of sub-streams constituting a video frame;
• determining whether an error occurs in each of the plurality of sub-streams;
• in response to determining that an error does not occur in any of the plurality of sub-streams and a reception of the plurality of sub-streams constituting the video frame is completed within a total transmission period, merging the plurality of sub-streams to generate the video frame;
• transmitting the video frame to a display that is electrically connected to the wireless receiving apparatus;
• and
• in response to determining that an error occurs in at least one of the plurality of sub-streams or the reception of the plurality of sub-streams constituting the video frame is not completed within the total transmission period, transmitting an immediately-preceding video frame to the display.
