responding to a feedback marking signal, generating a feedback information segment according to the feedback marking signal, and sending the feedback information segment to a main broadcasting terminal, wherein the feedback marking signal comprises the marking request signal, and the feedback information segment is used for performing problem feedback on the main broadcasting terminal according to the live content data.
7. The live broadcast data processing method according to claim 6, wherein the preset color extraction method performs color extraction on the live broadcast content data in real time to generate color simulation data, and the step of performing color simulation coverage on the live broadcast additional information according to the color simulation data specifically includes:
acquiring the live broadcast media information in the live broadcast content data, and acquiring the color and brightness of the live broadcast media information in real time according to a preset edge sampling rule to generate a light source simulation rule, wherein the light source simulation rule is used for performing color simulation coverage on the live broadcast additional information;
establishing a position corresponding relation between the live media information and the live additional information, wherein the position corresponding relation is used for representing the nearest position relation of each position of the image of the live additional information corresponding to the live media information when the live content data is output through the image;
and generating a covering light source layer according to the light source simulation rule, and performing color simulation covering on the live broadcast additional information by using the covering light source layer according to the position corresponding relation, wherein the covering light source layer is a semitransparent layer.
8. The live data processing method of claim 7, wherein the edge sampling rule includes a sampling range setting and a sampling direction setting, the sampling range setting is used for representing a ring-shaped area formed along an edge of the live media information output image at an equal distance from the edge to the inner side;
the sampling direction is set to characterize a shortest path direction pointing along an inside edge to an outside edge of the ring-shaped region.
