'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.

Parent Issues: How Life on Mars Negotiates a Television Generation Gap

In defining what he termed 'Television's Second Golden Age', Robert J.Thompson refers to characteristics such as being 'not regular TV', internal continuity, mixed genres but an aspiration towards 'realism', complex writing, self-consciousness and intertextuality. Such characteristics are displayed by the BBC series Life on Mars (2006-2007) which intermingles the Seventies tough cop show with psychological fantasy. This chapter examines the way that the series can be understood as a dramatisation of the negotiation that the creators undertook with their Seventies source material to update it for the values and qualities of contemporary television drama. It will emphasise the importance of television in the generation of the imagined 1973 and its characters, but also as an ongoing connection between the real and the imagined within the programme, including forming a breach of the boundaries between the two. Sam's actions within his Seventies world to remake it to include his own ideas of justice and due process while retaining the passion and freedom of action that the milieu provides will also be be examined in relation to the series' creators' needs to remake the Seventies tough-cop show in the light of modern social and media mores. The paper will also consider how Sam has to come to terms with his father's crimes, as the series' creators had to come to terms with the 'crimes' of taste, morality and approach of their 'parent' programmes from the Seventies' Golden Age.

Experimental Moments: R.U.R. and the Birth of British Television Science Fiction

Drawing on material from the BBC Written Archive Centre, this article examines the earliest sf dramas broadcast by the BBC Television Service: two adaptations of Karel Capek's "R.U.R." ("Rossum's Universal Robots") from 1938 and 1948. These productions are used as sites of formal experimentation with the possibilities of the new medium, representing one aspect of contemporary debates about the purpose of television and the style it would assume.

64-point Fourier transform chip for digital television applications

A 64-point Fourier transform chip is described that performs a forward or inverse, 64-point Fourier transform on complex two's complement data supplied at a rate of 13.5MHz and can operate at clock rates of up to 40MHz, under worst-case conditions. It uses a 0.6µm double-level metal CMOS technology, contains 535k transistors and uses an internal 3.3V power supply. It has an area of 7.8×8mm, dissipates 0.9W, has 48 pins and is housed in a 84 pin PLCC plastic package. The chip is based on a FFT architecture developed from first principles through a detailed investigation of the structure of the relevant DFT matrix and through mapping repetitive blocks within this matrix onto a regular silicon structure.

An enantioselective imprinted receptor for Z-glutamate exhibiting a binding induced color change

Using 1-(4-styryl)-3-(3-nitrophenyl)urea as host monomer for the imprinting of Z-(D or L)-Glu, a polymeric receptor exhibiting strong enantioselectivity and a change in color intensity upon binding of the guest was obtained.

A theoretical color-velocity correlation for supernovae associated with gamma-ray bursts

We carry out the first multi-dimensional radiative transfer calculations to simultaneously compute synthetic spectra and light curves for models of supernovae driven by fast bipolar outflows. These allow us to make self-consistent predictions for the orientation dependence of both color evolution and spectral features. We compare models with different degrees of asphericity and metallicity and find significant observable consequences of both. In aspherical models, we find spectral and light curve features that vary systematically with observer orientation. In particular, we find that the early-phase light curves are brighter and bluer when viewed close to the polar axis but that the peak flux is highest for equatorial (off-axis) inclinations. Spectral line features also depend systematically on observer orientation, including the velocity of the Si II 6355 Å line. Consequently, our models predict a correlation between line velocity and color that could assist the identification of supernovae associated with off-axis jet-driven explosions. The amplitude and range of this correlation depends on the degree of asphericity, the metallicity, and the epoch of observation but we find that it is always present and acts in the same direction. © 2012.

Real-time GPU color-based segmentation of football players

In this paper, we propose a multi-camera application capable of processing high resolution images and extracting features based on colors patterns over graphic processing units (GPU). The goal is to work in real time under the uncontrolled environment of a sport event like a football match. Since football players are composed for diverse and complex color patterns, a Gaussian Mixture Models (GMM) is applied as segmentation paradigm, in order to analyze sport live images and video. Optimization techniques have also been applied over the C++ implementation using profiling tools focused on high performance. Time consuming tasks were implemented over NVIDIA's CUDA platform, and later restructured and enhanced, speeding up the whole process significantly. Our resulting code is around 4-11 times faster on a low cost GPU than a highly optimized C++ version on a central processing unit (CPU) over the same data. Real time has been obtained processing until 64 frames per second. An important conclusion derived from our study is the scalability of the application to the number of cores on the GPU. © 2011 Springer-Verlag.

Anisotropy parameters in two-color two-photon above-threshold ionization

We employ the time-dependent R-matrix (TDRM) method to calculate anisotropy parameters for positive and negative sidebands of selected harmonics generated by two-color two-photon above-threshold ionization of argon. We consider odd harmonics of an 800-nm field ranging from the 13th to 19th harmonic, overlapped by a fundamental 800-nm IR field. The anisotropy parameters obtained using the TDRM method are compared with those obtained using a second-order perturbation theory with a model potential approach and a soft photon approximation approach. Where available, a comparison is also made to published experimental results. All three theoretical approaches provide similar values for anisotropy parameters. The TDRM approach obtains values that are closest to published experimental values. At high photon energies, the differences between each of the theoretical methods become less significant.

Design methodology for low power and arametric robustness through output-quality modulation:Application to color-interpolation filtering

Power dissipation and robustness to process variation have conflicting design requirements. Scaling of voltage is associated with larger variations, while Vdd upscaling or transistor upsizing for parametric-delay variation tolerance can be detrimental for power dissipation. However, for a class of signal-processing systems, effective tradeoff can be achieved between Vdd scaling, variation tolerance, and output quality. In this paper, we develop a novel low-power variation-tolerant algorithm/architecture for color interpolation that allows a graceful degradation in the peak-signal-to-noise ratio (PSNR) under aggressive voltage scaling as well as extreme process variations. This feature is achieved by exploiting the fact that all computations used in interpolating the pixel values do not equally contribute to PSNR improvement. In the presence of Vdd scaling and process variations, the architecture ensures that only the less important computations are affected by delay failures. We also propose a different sliding-window size than the conventional one to improve interpolation performance by a factor of two with negligible overhead. Simulation results show that, even at a scaled voltage of 77% of nominal value, our design provides reasonable image PSNR with 40% power savings. © 2006 IEEE.
