Network video processor RGB Networks announced today that its Simulcast Edge Processor (SEP) can aid cable operators’ subtitling capabilities on a neighborhood-by-neighborhood basis from a single headend.
RGB Networks’ SEP now supports SCTE-27-based subtitling for broadcast video programming, which allows cable operators to display subtitling in any language that is available in the programming.
RGB said the SEP takes advantage of the growing trend for programmers worldwide to encode their programming content with multiple subtitle tracks in order to reach more viewers. These subtitles are typically in several languages but are not visible to viewers.
Cable operators receive this programming at their central headends and select which subtitle track to display. With this method, only one subtitle track can be viewed by the subscribers served by that headend.
With RGB’s offering, operators can forward the programming from their central headends to outlying hubs that serve individual towns and neighborhoods. At these hubs, operators can use the SEP to select which subtitle track to display based on local demographics, thus delivering a more personalized viewing experience.
This capability is particularly useful for operators serving a multicultural subscriber base, in which multiple languages are spoken.
SCTE-27-based subtitles are based on a bitmap technique that enables support for subtitling in any language. The subtitle author is given complete control over the appearance of the characters.
