Approaches for coping with bandwidth limitations Erling Hedkvist – SVP Networked Audio Video Lawo 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 Doing more with less has become a mantra in today’s broadcast operations. Higher utilization Resolution and format boosts: more data need to be transported Users expect agile, scalable, multi -purpose solutions AIMS IP Showcase IBC 2019 September 2019 Curated by Video Services Forum vsf.tv 2 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 3 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 4 Codec must allow for: Multiple encoding and decoding passes Low latency Mezzanine compression ratios typically range from 2:1 to 10:1 AIMS IP Showcase IBC 2019 September 2019 Curated by Video Services Forum vsf.tv 3 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 J2K: (J2K Part 1) Most widely used wavelet -based codec. Royalty free VC -2: (Dirac) Lightweight mezzanine codec developed by BBC.

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.
