How video works today is set out in universal video standards which are negotiated by two organisations working together – the Digital Production Partnership (DPP) and the Society of Motion Picture and Television Engineers (SMPTE). These are specified in a universal standard called TSP 2121. This means that the same material can be shown on different devices. Through the use of standards a video on a smartphone or mobile device can be shown on a big television screen – a very different type of device. Video standards enable the automatic conversion from one device to another. 

By inserting the SafeCast HeadCode labels within the TSP 2121 standard it will be possible to enable filtering of content to protect children. This involves amending just one field in the definitions in TSP 2121 to include a SafeCast HeadCode. Once the HeadCode is included in the standards definition then lightweight filters in browsers and middleware can sift and remove inappropriate content by reading the HeadCode label. 

When this change is made to the TSP 2121 video standard then all devices will be capable of sifting content following a software update. National telecommunications regulators can require software updates to implement child protection on all devices.
