The International Review of Research in Open and Distance Learning (IRRODL) has dedicated a special issue to “Connectivism: Design and Delivery of Social Networked Learning” (March 2011), edited by George Siemens (Athabasca University, Canada) and Grainne Canole (Open University, UK).

This special issue is not meant as a definitive sum on connectivism but rather, as Terry Anderson, editor of IRRODL, put it in his announcement on the Instructional Technology Forum mailing list:

… a challenge and request that we spend more effort into trying to understand if connectivism has approaches and delivers important insights and practical designs into the increasing networked learning context in which we function.

Online Multimedia: Italian Imperialism

Accessibility 4 All by Claude Almansi

Italian bill on multimedia services

The Italian parliament is presently examining a government proposal of a decree that would modify the law on TV and radio towards the implementation of  “Directive 2007/65/EC [Webcite archived version] of the European Parliament and of the Council of 11 December 2007 amending Council Directive 89/552/EEC on the coordination of certain provisions laid down by law, regulation or administrative action in Member States concerning the pursuit of television broadcasting activities.”

The human-readable “schede di lettura” (reading notes) of the Camera dei deputati (Lower House) are available online [Webcite archived version]. The actual bill in legalese has not been officially published online, but an unofficial scan of a fax version is available from several sites, e.g., mcreporter.info/documenti/ac169.pdf (3.7 MB).

Online video = television

While the EU directive’s purpose is to take into account new on demand television offers, the definition of multimedia services in article 4 of the Italian bill also equates Web sites/platforms that offer online video to multimedia services subject to the same obligations stipulated by the bill as television broadcasters, unless their use of video is merely “incidental.” Among these obligations: editorial control, which means – in the case of web sites/platform offering videos – provider’s liability.

Jurisdiction

Article 2 of the Italian bill stipulates that media service providers – including sites/platforms hosting videos in a “non incidental” way, see above – situated in Italy are subject to Italian jurisdiction, i.e., to the bill. The bill’s definition of “situated in Italy” includes media service providers:

  • whose main seat is in Italy, even if editorial decisions are taken in another State of the EU
  • whose main seat is in Italy, even if service decisions are taken in another State of the EU
  • who use an earth-satellite up-link based in Italy

Moreover, article 3, about cross-border broadcasting, of the Italian bill stipulates that Italy  can ask, at the request of EU members, for the block of broadcasts from non-EU countries for motives of:

  • public order
  • protection of public health
  • safeguard of public safety, including national defense
  • consumers’ and investors’ protection

and impose a fine of Euro 150.00 – 150’000.00 if the non-EU provider does not comply with the blocking demand.

Paradox of timing restrictions for adult (pornographic, violent) content

One of the paradoxes of considering sites/platforms that offer videos as televisions subject to the bill appears in its article 9, about the protection of minors. This article stipulates that adult (pornographic or violent) content cannot be broadcast between 7 am and 11 pm.

As to the absurdity of applying such a timing limitation to videos offered on the web, see Kine’s ironic remark in the discussion Decreto Romani – Stop ai film vietati in TV e sul Web [Webcite archived version] started Jan. 21, 2010: “Come sarebbe anche al WEB scusa? Non [l]i guardo i film su youjizz dalle 7 alle 23?” (“What, also on the WEB? Can’t I watch videos on youjizz from 7 am to 11 pm?”)

Threat to accessibility

The Italian bill creates a similar absurdity for accessibility: it keeps the EU directive’s audiodescription and  captioning requirements for TV, but it threatens the possibility to use Web sites / platforms offering videos by submitting them to the same  conditions as TV channels. And even if a text-only offering of information and knowledge will pass automated accessibility tests, multimedia is a very important part of real accessibility for all.

The paradox here is that Italy has probably the best legal tools for furthering computer accessibility in EU, and maybe in the world, and actually works at implementing them. See the accessibile.gov.it site of the official observatory for accessibility in the public administration, which recently published Roberto Ellero’s tutorial on Accessibilità e qualità dei contenuti audiovisivi [Webcite archived version]  (Accessibility and quality of audiovisual content).

This tutorial fully integrates a text part and a video provided with Italian and English subtitles:

Webmultimediale

In the text part, Roberto Ellero refers to several pages of www.webmultimediale.org, the main site of  Webmultimediale, a project he founded for the study of online multimedia, and in particular of how the accessibility requirements for online multimedia can be a stimulus for creativity and a great help in education because these requirements also cater to various learning styles.

Webmultimediale is among the projects directly threatened by the bill’s equating of online videos with TV offerings. Not only does its www.webmultimediale.org site make a “non incidental” use of video, but it also has an open video hosting part, www.webmultimediale.it, where people upload their videos with a time-coded transcript in order to caption them. No way either could be maintained if the bill passes. Which means that Roberto Ellero’s tutorial on Accessibilità e qualità dei contenuti audiovisivi [Webcite archived version], commissioned by the government’s Observatory of accessibility in the public administration, would be severely maimed.

I happen to participate in the Webmultimediale project. The jurisdiction conditions in the bill made me think of a discussion about Web accessibility Roberto and I animated at the end of last November. Roberto lives in Venice; I, in Geneva. The discussion venue was the Instructional Technology Forum mailing list, based at the University of Georgia (US) but with subscribers from all over the world, and how we all used variously hosted e-mail accounts. So where were “editorial” decisions made, in so far as there were any? Were they made, e.g., when I embedded a California-hosted YouTube video, made by Roberto in Venice, in the Florida-hosted wiki that we used for background material and, later, to gather the discussion threads? Under what jurisdiction did I do that?

Threat to education

Beyond the Webmultimediale example above, it is the use of multimedia in Italian education that is put at risk by the bill. If it becomes law, what teachers and educational institutions will dare offer a video podcast of lectures, scientific experiments, and use of video in teaching under the threat of being asked to comply with the administrative requirements imposed by the bill for TV broadcasters? Even if they try to upload the videos on a foreign platform and link to them, there would still be a risk that the foreign platform will be considered a television broadcaster and blocked in Italy.

Live Radio Captioning for the Deaf

Thanks to:

  • Sylvia Monnat, director of captioning at Télévision Suisse Romande (French-speaking Swiss television www.tsr.ch) for the explanations she gave me by phone on live captioning through re-speaking.
  • Neal Stein, of Harris Corporation (www.harris.com), for the authorization to publish on YouTube the video excerpt shown below, and for his explanations on the US live radio captioning project.

Why Caption Radio?

Making radio accessible for deaf and hard of hearing persons is not commonly perceived as a priority. For instance, the new version of the Swiss law and ordinance on Radio and Television that came into force in 2007 does add several dispositions about accessibility for people with sight and hearing disabilities but does not mention captioning radio. See art. 7 [1] of the law and art. 7 [2] and 8 [3] of the ordinance (in French). According to most non-deaf people’s “common sense,” deaf persons don’t use radio – just as many non-blind people still believe that blind people can’t use computers.

Yet deaf persons are interested in accessing radio content through captioning, as Cheryl Heppner, Executive Director of NVRC [4], explains in this video:

The video is from the January 8, 2008, I-CART introductory press conference at CES 2008. The full video can be downloaded from www.i-cart.net. Transcript of the above excerpt:

I’m one of 31 million people in the United States who are deaf or hard of hearing. A number that continues to grow. NPR Labs and its partners are on the verge of making many of my dreams come true. Beyond having that really crucial emergency information, captioned radio could also open up a world I’ve never had, because I lost my hearing before my seventh birthday.

When I am stuck in Washington’s legendary Beltway gridlock, I could check the traffic report and find out why, what my best route would be. I could check the sports scores and follow the games for all my favorite teams. I could know why my husband is always laughing so uproariously when he listens to “Car Talk.” And I could annoy him by singing along badly to the lyrics of his favorite songs.

I can’t wait. Thank you.

NPR’s Live Captioned Broadcast of Presidential Election

The work by NPR Labs and its partners, mentioned by Cheryl Heppner in this January 2008 conference, led to the broadcasting of live captioned debates on NPR during the US election campaign a few months later. The assessment by deaf and hard of hearing people of this experiment was extremely positive. According to the press release “Deaf and Hard of Hearing Vote Yes on New Radio Technology During NPR’s Live Captioned Broadcast of Presidential Election” (Nov. 13, 2008) [5]:

  • 95% were happy with the level of captioning accuracy, a crucial aspect for readability and comprehension
  • 77% said they would be interested in purchasing a captioned radio display unit when it becomes available
  • 86% indicated they would be interested in purchasing a “dual-view” screen display for a car (which would enable a deaf passenger to see the captioned radio text while the driver listens to the radio).

How Are Radio Captions Transmitted?

A digital radio signal can be divided to transmit audio and text, and the text can be read on the radio display. In fact, text messages are already being sent micro4_serviceon car radio displays through Radio Data System (RDS). For instance, this is how the Swiss traffic information service Inforoutes updated drivers in real time – or almost – about the state of traffic jams due to work in the Glion tunnel in 2004. (See “Service,” in French, on page 4, in the May 2004 newsletter of Les Radios Francophones Publiques [6].)

The radio devices used in the experience conducted by NPR Labs and its partners that Cheryl Heppner mentions have a bigger display. For the exact technical explanation of how the captions work, see the presentations section of www.i-cart.net.

Stenocaptioning vs. Respeaking

The NPR experiment mentioned above used “stenocaptioned,” i.e., they were written with a stenotype [7] whose output gets translated into captions in normal English by computer software. Live stenocaptioning – whether for news broadcasts or for in-presence events in specially equipped venues – seems to be the preferred solution in countries such as the US and Italy that have a tradition of stenotyping court proceedings or parliamentary debates.

In most other European countries, according to Ms. Sylvia Monnat, director of captioning at Télévision Suisse Romande (French-speaking Swiss TV – www.tsr.ch), broadcasters tend to prefer “respeaking,” which works with speech-to-text technology: the software gets trained to recognize the voice of respeakers, and then converts what they repeat into captions.

Ms. Monnat further explained that, on the one hand, the advantages of respeaking involves training. In fact, countries without a stenotyping tradition do not offer courses for it, whereas existing interpretation schools can arrange respeaking courses since it is a normal exercise in the training of conference interpreters. Moreover, respeaking is easier to learn than stenotyping.

On the other hand, it takes time to, first, train the speech-to-text software to recognize the respeakers’ voices and, second, to add words not present in its basic thesaurus for each respeaker’s voice. Moreover, enough respeakers have to be trained so that one whose voice is recognized by the software will be available when needed. Whereas once a new word has been added to the thesaurus of the stenocaptioning software, it can be used by any stenocaptioner.

Outlook

The fast evolution of technology makes it difficult to foresee the issues of live captioning, even in the near future. Radio and television are merging into “multimedia broadcasting.” And, in turn, the line between broadcasting and the internet is gradually fading (see the HDTV offer by internet providers). Speech-to-text technology will probably continue to improve. Mutimedia devices are also evolving rapidly.

However, the response of the deaf and hard of hearing people who participated in the NPR Live captioning experiment seems to allow one safe surmise: live radio captioning is here to stay, whatever the means it will use tomorrow.
