Royalty free VC -2: (Dirac) Lightweight mezzanine codec developed by BBC. Royalty free Tico: Lightweight mezzanine codec from intoPIX JPEG XS : A new JPEG standard from Fraunhofer and intoPIX HT -J2K : (J2K Part 15) Based on JPEG 2000.

Software -definable processing blades 3. Blades become "containers" or "nodes", i.e. processing clusters AIMS IP Showcase IBC 2019 September 2019 Curated by Video Services Forum vsf.tv 4 I P S H O W C A S E T H E AT R E AT I B C 2 0 1 9 : 1 3 –1 7 S E P T 2 0 1 9 7 Cluster: a group of processing units that work together towards a common goal Defined amount of processing instances selected by user One processing unit = master, all others = slaves Any slave takes over from a defective one Master is automatically replaced when necessary I P S H O W C A S E T H E AT R E AT I B C 2 0 1 9 : 1 3 –1 7 S E P T 2 0 1 9 8 Replaceable instances perform a given task. Users only care about aggregate output Inherently self -healing Ability to easily scale up/down by adding/removing capacity Ability to prioritize: highest availability for important results Load balancing Easy management via master (single point of contact) Freely mix and match interface speeds (10, 25, 40, 50, 100…) AIMS IP Showcase IBC 2019 September 2019 Curated by Video Services Forum vsf.tv 5 I P S H O W C A S E T H E AT R E AT I B C 2 0 1 9 : 1 3 –1 7 S E P T 2 0 1 9 9 Example: Lawo V__matrix vm_dmv distributed multiviewer application I P S H O W C A S E T H E AT R E AT I B C 2 0 1 9 : 1 3 –1 7 S E P T 2 0 1 9 10 The open standards -based IP technology employed allows cluster members to be: Co -located on -campus and/or next to one another Distributed over multiple sites and accessed via WAN AIMS IP Showcase IBC 2019 September 2019 Curated by Video Services Forum vsf.tv 6 I P S H O W C A S E T H E AT R E AT I B C 2 0 1 9 : 1 3 –1 7 S E P T 2 0 1 9 11 Responsible users: allocate processing units according to the m+n principle: m: number of units required for a given task n: number of spare units set aside for redundancy purposes.
