Channel 4 is a British free-to-air public broadcast television channel owned and operated by the state-owned Channel Four Television Corporation. It is publicly owned but, unlike the BBC, it receives no public funding and is instead funded entirely by its own commercial activities, including publicity. It began its transmission in 1982 and was established to provide a fourth television service in the United Kingdom. At the time, the only other channels were the licence-funded BBC One and BBC Two, and a single commercial broadcasting network ITV. Originally a subsidiary of the Independent Broadcasting Authority (IBA), the station is now owned and operated by Channel Four Television Corporation, a public corporation of the Department for Culture, Media and Sport, which was established in 1990 and came into operation in 1993. Until 2010, Channel 4 did not broadcast in Wales, but many of its programmes were re-broadcast there by the Welsh fourth channel S4C. In 2010, Channel 4 extended se

A tight bound on the performance of a minimal-delay joint source-channel coding scheme

Marius Kleiner, Bixio Rimoldi

An analog source is to be transmitted across a Gaussian channel in more than one channel use per source symbol. This paper derives a lower bound on the asymptotic mean squared error for a strategy that consists of repeatedly quantizing the source, transmitting the quantizer outputs in the first channel uses, and sending the remaining quantization error uncoded in the last channel use. The bound coincides with the performance achieved by a suboptimal decoder studied by the authors in a previous paper, thereby establishing that the bound is tight.

Asymptotically Optimal Joint Source-Channel Coding with Minimal Delay

Marius Kleiner, Bixio Rimoldi

We present and analyze a joint source-channel coding strategy for the transmission of a Gaussian source across a Gaussian channel in n channel uses per source symbol. Among all such strategies, the scheme presented here has the following properties: i) the resulting mean-squared error scales optimally with the signal-to-noise ratio, and ii) the scheme is easy to implement and the incurred delay is minimal, in the sense that a single source symbol is encoded at a time.
