Abstract: According to an aspect. there is provided a treatment device (2; 400) for performing light-based treatment operations on or to a subject. The treatment device (2; 400) comprises a U-shaped light source (12; 202; 301; 402) for emitting a light pulse; a light exit window (10; 201) through which the light pulse is emitted from the treatment device (2; 400); and a reflector (302; 403) for reflecting the light pulse towards the light exit window (10; 201). The treatment device (2; 400) is configured to operate with the light source (12; 202; 301; 402) and the reflector (302; 403) in a first configuration (210; 310, 320) for performing hair removal on the subject. and with the light source (12; 202; 301; 402) and the reflector (302; 403) in a second configuration (220; 330) for performing skin rejuvenation on the subject.

Abstract: Embodiments are directed to pacing on-demand linear advertisement entries to appear as being live entries, to generating a sequential segment map from a parallel playlist and to consolidating linear ad and main content portions into a single linear chunklist. In one embodiment, a computer system receives video content updates for a portion of live video programming, and generates a parallel playlist with parallel playlist entries that identify a presentation that is to be played. The computer system then generates a sequential segment map from the parallel playlist that identifies which parallel playlist entry is to be played, monitors a live position for new media, determines that an on-demand linear advertisement is to be played at the live position, and appends on-demand linear advertisement chunks to a chunklist to replace the main content chunks and play the on-demand linear advertisement entries in a pseudo-live format as if they were live.
