Broadband is a high-speed, high-capacity data transmission medium that can carry multiple signals by dividing the total capacity into multiple channels Broadband Television (BTV) is the provision of linear, scheduled television services and Video on Demand (VOD) services over a two-way broadband ifinfrastructure prov iddbided by te lecommun icat ions carr iers to en d consumers, who use the service via a set top box and display, or via an integrated TV receiver.

The results are given in the Article published in the EBU Technical Review in April 2005. Main conclusions: BTV has a great market potential. It is able to provide a bundle of media services (e.g. triple play) including IPTV - managed television services over IP based networks Internet TV – unmanaged television services. These TV services consist of Linear TV (channels) Video on Demand (()VoD) Near VoD and Catch-up TV Scheduled VoD (push overnight) Video Podcasting EBU TECHNICAL - your reference in media technology and innovation IPTV deppyloyments All major western countries and most developed economies have IPTV deployments The world's leading markets for IPTV for now are France (over 4 million subscriptions) Free Orange Neuf Cegetel South Korea (1.8 million subscriptions), Hong Kong Japan Italy, Spain, Belgium, China, Switzerland, Slovenia, Croatia, Scandinavia UK launched IPTV early but has been slow to Significant plans exist in countries such as Poland and Russia.

Broadcaster’ s branding needs to be visible across all platforms. Broadcast content should be repurposed to suit optimally to different displays and pipelines. BdtBroadcast con ttdtbtent needs to be secured dd and prot ttdected. Visibility of broadcasters’ content in programme guides should be appropriate and adapted to media situation in a given market . Broadcasters desire to maintain end-to-end control of signal quality. No filtering of associated services and metadata is allowed.
