The arrival of the era of big data and integrated media has changed the way of media communication and broken the original single media narrative model. The interaction and communication between traditional media and emerging media have formed a new paradigm of narrative, i.e., cross-media narrative. Based on the purpose of studying the cross-media narrative ability cultivation system of screenwriting art talents, this paper analyzes the market growth of cross-media narrative works in the era of integrated media and the audience’s perceptions of cross-media narrative works such as IP adaptations using the K-means clustering method. From 2018 to 2021, the market share of cross-media narrative works grew from 21.1% to 35.3%, while traditional single-media narrative works declined by 34.76%. Faced with the surge of transmedia narrative works, 29.5% of viewers think the stories are unattractive, too homogeneous, and lack freshness. Another 24.6% of viewers think that the plot lacks originality and only copies novels. Another 33.2% of viewers think there is plagiarism and piracy. The current cross-media narrative works still have many problems, such as rough production and a lack of polished plots. The education of film and television scriptwriting should focus on the cultivation of cross-media narrative quality, the enhancement of cross-media narrative ability, and the training of cross-media narrative skills for scriptwriting talents to cultivate high-level applied scriptwriting talents who can connect with the industry.

In space laser communication, the wide divergence angle of beacon light leads to substantial spatial losses, compounded by background light and detector noise; this results in compromised precision in the detection of the beacon light position. To solve this problem, a high-precision detection technique and communication composite technology employing a four-quadrant detector (QD) with beacon spread-spectrum modulation are proposed. Pseudo-random sequences (PRNs) are employed to spread the beacon communication spectrum, with the spread-spectrum signal utilized to modulate the intensity of the transmitted beacon light at the transmitter end. At the receiver, QD photocurrent signals are cross-correlated with an identical PRN that is used for modulation. The strong auto-correlation properties of PRNs, which are uncorrelated with noise, enhance the output signal-to-noise ratio (SNR), enabling precise position detection and beacon communication under high-SNR conditions. Theoretical analysis is used to explore the effects of spreading gain on the sensitivity of system detection and the precision of position detection. The experimental results demonstrate that the beacon spread-spectrum modulation scheme effectively detects the position of the light spot. At a received optical power of −37 dBm and spreading sequence PRN depths of 1023, 127, and 31, the root-mean-square error (RMSE) values are 0.983 μm, 2.876 μm, and 7.275 μm, respectively. This corresponds to improvements of 14.96 dB, 10.29, dB, and 6.26 dB compared to direct detection precision (30.811 μm). Additionally, under an identical signal bandwidth, the sensitivity improves by 14.6 dB, 10.1 dB, and 6.4 dB, respectively. The proposed beacon spread-spectrum scheme mitigates the limitations of hardware reception sensitivity and position-detection precision, demonstrating its potential application in high-precision detection in long-distance interstellar laser communication.
