Audio Description for Educational Videos on COVID-19 Response:A Corpus-Based Study on Linguistic and Textual Idiosyncrasies

Audio description(AD),unlike interlingual translation and interpretation,is subject to unique constraints as a spoken text.Facilitated by AD,educational videos on COVID-19 anti-virus measures are made accessible to the visually disadvantaged.In this study,a corpus of AD of COVID-19 educational videos is developed,named“Audio Description Corpus of COVID-19 Educational Videos”(ADCCEV).Drawing on the model of Textual and Linguistic Audio Description Matrix(TLADM),this paper aims to identify the linguistic and textual idiosyncrasies of AD themed on COVID-19 response released by the New Zealand Government.This study finds that linguistically,the AD script uses a mix of complete sentences and phrases,the majority being in Present Simple tense.Present participles and the“with”structure are used for brevity.Vocabulary is diverse,with simpler words for animated explainers.Third-person pronouns are common in educational videos.Color words are a salient feature of AD,where“yellow”denotes urgency,and“red”indicates importance,negativity,and hostility.On textual idiosyncrasies,coherence is achieved through intermodal components that align with the video’s mood and style.AD style varies depending on the video’s purpose,from informative to narrative or expressive.

Real-time Audio &Video Transmission System Based on Visible Light Communication

With the increasing popularity of solid sate lighting devices, Visible Light Communication (VLC) is globally recognized as an advanced and promising technology to realize short-range, high speed as well as large capacity wireless data transmission. In this paper, we propose a prototype of real-time audio and video broadcast system using inexpensive commercially available light emitting diode (LED) lamps. Experimental results show that real-time high quality audio and video with the maximum distance of 3 m can be achieved through proper layout of LED sources and improvement of concentration effects. Lighting model within room environment is designed and simulated which indicates close relationship between layout of light sources and distribution of illuminance.

Integrating Audio-Visual Features and Text Information for Story Segmentation of News Video

Video data are composed of multimodal information streams including visual, auditory and textual streams, so an approach of story segmentation for news video using multimodal analysis is described in this paper. The proposed approach detects the topic-caption frames, and integrates them with silence clips detection results, as well as shot segmentation results to locate the news story boundaries. The integration of audio-visual features and text information overcomes the weakness of the approach using only image analysis techniques. On test data with 135 400 frames, when the boundaries between news stories are detected, the accuracy rate 85.8% and the recall rate 97.5% are obtained. The experimental results show the approach is valid and robust.

Content-Based Hierarchical Analysis of News Video Using Audio and Visual Information

A schema for content-based analysis of broadcast news video is presented. First, we separate commercials from news using audiovisual features. Then, we automatically organize news programs into a content hierarchy at various levels of abstraction via effective integration of video, audio, and text data available from the news programs. Based on these news video structure and content analysis technologies, a TV news video Library is generated, from which users can retrieve definite news story according to their demands.

Patient interest in video recording of colonoscopy:A survey

AIM:To find if patients are interested in obtaining a video recording of their colonoscopy procedure.METHODS:We conducted a survey of outpatients presenting for colonoscopy regarding their interest in obtaining a video recording of their colonoscopy.RESULTS:Two hundred and forty-eight patients(mean age 57.9 years;57% male) were surveyed.Two hundred and one patients(81%) were interested in obtaining a video recording.No significant predictors of patients' interest in the video recording were identified.After reading a brief educational paragraph explaining missed lesions during colonoscopy,135 patients(54%) were more interested in having a video recording,and none were less interested.One hundred and fifty-six patients(63%) were willing to pay for a video recording.In multivariable analyses,younger age was predictive of willingness to pay for a video recording.Prior history of colorectal cancer and a family history of colorectal cancer were predictive of willingness to pay a greater amount.CONCLUSION:Patients undergoing colonoscopy expressed substantial interest in obtaining a videorecording of their procedure.Awareness of missing lesions during colonoscopy increased interest in having a videorecording.

Study on an Audio and Video Network Monitoring System for Weather Modification Operation

An audio and video network monitoring system for weather modification operation transmitting information by 3G, ADSL and Internet has been developed and applied in weather modification operation of Tai＇an City. The all-in-one machine of 3G audio and video network highly integrates all front-end devices used for audio and video collection, communication, power supply and information storage, and has advantages of wireless video transmission, clear two-way voice intercom with the command center, waterproof and dustproof function, simple operation, good portability, and long working hours. Compression code of the system is transmitted by dynamic bandwidth, and compression rate varies from 32 kbps to 4 Mbps under different network conditions. This system has forwarding mode, that is, monitoring information from each front-end monitoring point is trans- mitted to the server of the command center by 3G/ADSL, and the server codes＇and decodes again, then beck-end users call images from the serv- er, which can address 3G network stoppage caused by many users calling front-end video at the same time. In addition, the system has been ap- plied in surface weather modification operation of Tai＇an City, and has made a great contribution to transmitting operation orders in real time, monitoring, standardizing and recording operating process, and improving operating safety.

Video recording of neonatal resuscitation:A feasibility study to inform widespread adoption

AIM To determine the feasibility of introducing video recording(VR) of neonatal resuscitation(NR) in a perinatal centre.METHODS This was a prospective cohort quality improvement study on preterm infants and their caregivers.Based on evidence and experience of other centers using VR intervention,a contextually relevant implementation and evaluation strategy was designed in the planning phase.The components of intervention were pre-resuscitation team huddle,VR of NR and video debriefing(VD),all occurringon the same day.Various domains of feasibility and sustainability as well as feasibility criteria were predefined.Data for analysis was collected using quantitative and qualitative methods.RESULTS Seventy-one caregivers participated in VD of 14 NRs facilitated by six trained instructors.Ninety-one percent of caregivers perceived enhanced learning and patient safety and,48 issues were identified related to policy,caregiver roles,and latent safety threats.Ninety percent of caregivers expressed their willingness to participate in VD activity and supported the idea of integrating it into a resuscitation team routine.Eighty-three percent and 50% of instructors expressed satisfaction with video review software and quality of audio VR.No issues about maintenance of infant or caregivers' confidentiality and erasure of videos were reported.Criteria for feasibility were met(refusal rate of < 10%,VR performed on > 50% of occasions,and < 20% caregivers' perceiving a negative impact on team performance).Necessary adaptations to enhance sustainability were identified.CONCLUSION VR of NR as a standard of care quality assurance activity to enhance caregivers' learning and create opportunities that improve patient safety is feasible.Despite its complexity with inherent challenges in implementation,the intervention was acceptable,implementable,and potentially sustainable with adaptations.

audio和video

电视上看到一则某种牌子的电器之广告,内中有audio和video两个字,借贵刊一角谈一谈。不用说,这两个字都是和电器有关的。audio与“音”有关系,video则和“影”有关。 audio是指由声音、机械、或电力所造成的频率(audio frs-quency),具有这种频率的声波每秒钟振动十五至二万次,也就是所谓低周波,是人类所能听得见的。在电器制品中,andio 特指电唱机、收音机或电视机的发音部分,平常人们所说的音响设备就叫audio equipment。因此,audio现用来泛指一般与音响有关的东西。
