Public Service Broadcasting, Creative Industries and Innovation Infrastructure: The Case of ABC's Pool

The proliferation of media services enabled by digital technologies poses a serious challenge to public service broadcasting rationales based on media scarcity. Looking to the past and future, we articulate an important role that the Australian Broadcasting Corporation (ABC) might play in the digital age. We argue that historically the ABC has acted beyond its institutional broadcasting remit to facilitate cultural development and, drawing on the example of Pool (an online community of creative practitioners established and maintained by the ABC), point to a key role it might play in fostering network innovation in what are now conceptualised as the creative industries.

iLectures - Exploring the interactive lecture using web-based broadcasting technology

The continued use of traditional lecturing across Higher Education as the main teaching and learning approach in many disciplines must be challenged. An increasing number of studies suggest that this approach, compared to more active learning methods, is the least effective. In counterargument, the use of traditional lectures are often justified as necessary given a large student population. By analysing the implementation of a web based broadcasting approach which replaced the traditional lecture within a programming-based module, and thereby removed the student population rationale, it was hoped that the student learning experience would become more active and ultimately enhance learning on the module. The implemented model replaces the traditional approach of students attending an on-campus lecture theatre with a web-based live broadcast approach that focuses on students being active learners rather than passive recipients. Students ‘attend’ by viewing a live broadcast of the lecturer, presented as a talking head, and the lecturer’s desktop, via a web browser. Video and audio communication is primarily from tutor to students, with text-based comments used to provide communication from students to tutor. This approach promotes active learning by allowing student to perform activities on their own computer rather than the passive viewing and listening common encountered in large lecture classes. By analysing this approach over two years (n = 234 students) results indicate that 89.6% of students rated the approach as offering a highly positive learning experience. Comparing student performance across three academic years also indicates a positive change. A small data analytic analysis was conducted into student participation levels and suggests that the student cohort's willingness to engage with the broadcast lectures material is high.

Special issue on design and programming of signal processors for multimedia communication:Special issue on design and programming of signal processors for multimedia communication

The technical challenges in the design and programming of signal processors for multimedia communication are discussed. The development of terminal equipment to meet such demand presents a significant technical challenge, considering that it is highly desirable that the equipment be cost effective, power efficient, versatile, and extensible for future upgrades. The main challenges in the design and programming of signal processors for multimedia communication are, general-purpose signal processor design, application-specific signal processor design, operating systems and programming support and application programming. The size of FFT is programmable so that it can be used for various OFDM-based communication systems, such as digital audio broadcasting (DAB), digital video broadcasting-terrestrial (DVB-T) and digital video broadcasting-handheld (DVB-H). The clustered architecture design and distributed ping-pong register files in the PAC DSP raise new challenges of code generation.

'Strange Visitor From Another Planet': Genre, Corporate Identity and the Arrival of American Telefantasy on British Television

While the BBC had been broadcasting television Science Fiction productions from as early as 1938, and Horror since the start of television in 1936, American Telefantasy had no place on British television until ITV’s broadcast of Adventures of Superman (1952-1958) in 1956. It would be easy to assign this absence to the avoidance of popular American programming, but this would ignore the presence of Western and adventure serials imported from the US and Canada for monopoly British television. Similarly, it would be inaccurate to suggest that these imports were purely purchased as thrilling fare to appease a child audience, as it was the commercial ITV that was first to broadcast the more adult-orientated Science Fiction Theatre (1955-7) and Inner Sanctum (1954). This article builds on the work of Paul Rixon and Rob Leggott to argue that these imports were used primarily to supply relatively cheap broadcast material for the new channel, but that they also served to appeal to the notion of spectacular entertainment attached to the new channel through its own productions, such as The Invisible Man (1958-1959) and swashbucklers such as The Adventures of Robin Hood (1955-60). However, the appeal was not just to the exciting, but also to the transatlantic, with ITV embracing this conception of America as a modern place of adventure through its imports and its creation of productions for export, incorporating an American lead into The Invisible Man and drawing upon an (inexpensive) American talent pool of blacklisted screenwriters to provide a transatlantic style and relevance to its own adventure series. Where the BBC used its imported serials as filler directed at children, ITV embraced this transatlantic entertainment as part of its identity and differentiation from the BBC.

HIGH-FIDELITY MUSIC CODING AT 4 BITS.

A very high-quality sub-band ADPCM music coding scheme which compresses high-fidelity music signals, bandlimited to 15kHz, to an equivalent PCM representation of only 4 bits per sample, is described. By processing music sampled at 32 kHz, this coder exhibits a total bit rate of only 128kbit/s and is consequently applicable to the ISDN. Subjective tests conducted with this coder have shown that music recovered from the compression scheme is essentially indistinguishable from the original material. The results obtained are of major importance, not only for ISDN and broadcasting, but also for other digital audio technology such as compact disc (CD) and digital audio tape.
