Design a Cinema Auditorium, How To – Rolv Gjestland

There should be laws against putting this much data, with this much nuance, with this much extraordinary organization and pictures and explanation. …or, awards perhaps. Yes, awards.

There is a new document online from the European cinema organization named UNIC. Subtitled as the Practical Guidelines for Architects, Cinema Owners and Others Involved in Planning and Building Cinemas, the How to Design A Cinema Auditorium book is 65 pages of very strait forward and coherent information. It can be downloaded from <https://unic-cinemas.org/fileadmin/CinemaAuditoriumDesign_v1.0.pdf>  

Rolv Gjestland has been working for the Norwegian Cinema nonprofit trade organisation Film&Kino since 1984. He is their consultant in cinema technology and cinema design.

Technicolor Starting On the Long Glossary Road

Back in the late 80’s the digital transition grabbing the attention of engineers was in the broadcast business…no, in the post-production equipment business…no, it was in the potential of both…actually, memory was still expensive and processing power was still locked by unreleased new versions of the Motorola 68000 and other chips which drove everyone’s imagination with expectations of clever glued matrixes of parallel’d A/V ideas…most all failed as the latest versions didn’t arrive until too late – well, not too late for those companies who bought the dreamer companies for pennies on the dollar.

Notwithstanding that tangent, it was interesting times with new names and acronyms and uses for ideas – and the clever folks at Quantel issued their first industry glossary. It got better and better with each edition. The latest is the 20th Edition, released in 2015…and available at this link: Quantel Digital Factbook

There are plenty of other Glossaries at the DCinemaTools Glossary page.

Technicolor has started on the road to a new glossary named the Next Gen Premium Entertainment Experiences, which sounds like something that should be given out by the Event Cinema Association. Instead, it is pages of explanations of better bits. Click on the title.

Five Reasons Classic Ethernet Switches Won’t Support the Cloud

When a company starts looking at providing cloud services to its clients, or consuming cloud services itself, it often becomes quickly apparent that the network needs to be upgraded to support this new service delivery model.


From an Internet.com article: 
Five Reasons Classic Ethernet Switches Won’t Support the Cloud.
By Drew Robb


“External and hybrid cloud models mean that computing resources are remote, and access/ communications with those workloads will have to traverse a wide area or Internet network link,” says Jim Frey Managing Research Director of analyst firm Enterprise Management Associates. “This introduces substantially greater latency (and bandwidth constraints) than are normal for traditional campus/data center-based computing.”

Before implementing cloud computing, therefore, it is critical to examine the strength of the network to make sure that any weak points are located and eliminated. This helps to ensure …

1. Classic Ethernet Networks are Hierarchical

Ethernet typically relies on a hierarchy of three or more tiers. Moving traffic between different server racks, for example, requires transitioning up and down this logical tree. The important point here is that each step along the path adds to the total latency. To avoid bridge loops between different network segments, IEEE 802.1D Spanning Tree Protocol (STP) allows only one active path at a time between two switches. However, …

2. Classic Ethernet Networks are Unintelligent

Classic switches are designed to connect physical, not virtual, resources. Each port is individually configured with the QoS, security, VLAN traffic and other network policies required by that particular server. In a virtual world, however, VMs move from one box to another depending on traffic loads or maintenance requirements. Unless the port configuration follows the VM to its new physical location, …

3. Classic Ethernet Networks Don’t Scale

Since Classic Ethernet networks are designed to allow only a single connection between switches, this limits the amount of traffic they can carry.

“The scalability of traditional Ethernet is problematic, especially if an organization assumes, as it nearly always will, that cloud infrastructures will grow,” says Charles King, Principal Analyst at Pund-IT, Inc. “That said, …

To reduce the impact of this bottleneck, link aggregation groups (LAGs) permit multiple physical links to share the ISL. But this requires …

4. Classic Ethernet Networks Are Inefficient

Due to the limitations of STP, only one link or LAG can be active at a time, lowering the utilization rate. Adding or removing a new link causes the entire network to pause …

5. Classic Ethernet Networks Are Complex

With classic Ethernet networks, each port on each switch needs to be configured with the applicable VLANs, QoS, security, network policies and protocols. As servers are added, …

Switching to Fabric

To eliminate the various bottlenecks caused by traditional Ethernet architectures, switch vendors have begun to adopt fabric architecture into their Ethernet switches. This eliminates or mitigates each of the problems listed above.

Fabric switches flatten the network, reducing latency by eliminating unnecessary steps and preventing bottlenecks …

Classic or Fabric?

When is a classic Ethernet network adequate and when should one change to an Ethernet fabric? It depends on the applications. Some applications require large amounts of raw throughput; transaction systems are sensitive to latency.

“It comes back to what is the workload one is trying to project up into the cloud,” says Dan Kusnetzky, analyst and founder of the Kusnetzky Group. “Until we know more about the application and its requirements, … Ultimately, though, some network upgrades and enhancements will be in your future.”
