IPCM: Intra pulse-code modulation (similar in spirit to IPCM in AVC).
JM: Joint model – the primary software codebase that has been developed for the AVC standard.
JSVM: Joint scalable video model – another software codebase that has been developed for the AVC standard, which includes support for scalable video coding extensions.
LB or LDB: Low-delay B – the variant of the LD conditions that uses B pictures.
LC: Low complexity – a set of coding capabilities designed for reduced implementation complexity (contrast with HE). Often loosely associated with LD.
LD: Low delay – one of two sets of coding conditions designed to enable interactive real-time communication, with less emphasis on ease of random access (contrast with RA). Often loosely associated with LC. Typically refers to LB, although also applies to LP.
