Convergence is ongoing across the communications and entertainment markets. Video content is now accessible via numerous channels, beyond traditional services such as terrestrial, cable and satellite and towards online and mobile platforms. As a result, the online and broadcast markets are colliding, with video services making the move to the PC environment and web-based services becoming a core element of the TV viewing experience. There are an ever-expanding number of channels available for content to be distributed over and an ever-increasing range of technologies to aid the transmission.
