Today's video contribution networks are evolving rapidly, driven both by increased demand, including high definition TV, and a need for reduced cost of ownership. The Cisco® DCM Series D9901 Digital Content Manager (DCM) IP Video Gateway, shown in Figure 1, is a compact 1 rack unit (1RU), serial digital interface (SDI) video gateway platform capable of supporting the delivery at full quality of a high number of uncompressed video signals, as well as JPEG2000 compressed video signals over cost-effective Ethernet links.
Figure 1. Cisco DCM Series D9901 Digital Content Manager - IP Video Gateway
The DCM Series D9901 IP Video Gateway provides simultaneous transport of uncompressed standard-definition (SD), high-definition (HD), and 3G high definition (3G-HD) SDI video, as well as compressed video using JPEG2000. At the transmitter site, the DCM IP Video Gateway enables SDI video to be carried over 1 Gigabit Ethernet or 10 Gigabit Ethernet. At the receiving site, the DCM IP Video Gateway converts the IP-encapsulated stream back to a baseband SDI video signal.
Because of its quality, flexibility, and very compact design, the DCM Series D9901 IP Video Gateway is adaptable for a wide range of applications, including professional broadcast contribution, studio-to-studio media exchange, in-house signal distribution and routing, post-production, and live event coverage, including transport of full resolution 3D signals.
As IP is becoming more and more the transport network of choice, it's important to maximize quality of service. The DCM IP Video Gateway's extensive set of IP over Gigabit Ethernet features including extensive protocol support allows for a seamless integration with these IP networks. For highest quality of service transport the DCM IP Video Gateway provides a Hitless Merge feature that allows for uninterrupted video transport in case of severe network failures.
The DCM IP Video Gateway comes in a compact 1RU chassis. The unit can be configured with up to two gateway cards, with each card having dual Gigabit Ethernet ports and up to six SDI video ports.
The gateway cards can be individually configured with either electrical video interfaces or optical video interfaces, or a combination of both.
With electrical interfaces, the gateway can be equipped with either six electrical SDI inputs, or six electrical SDI outputs, or the combination of three SDI inputs and three SDI outputs. With optical interfaces, the gateway can be equipped with either six optical ports, or a combination of three optical SDI ports and three electrical SDI ports (either three inputs or three outputs). The optical ports are based on unidirectional video small form-factor pluggables (SFPs). The user defines the port direction by plugging in either a receiver SDI SFP or a transmitter SDI SFP.
Each gateway card is equipped with a main and a backup Ethernet port. The ports are software switchable to function as either 1 Gigabit Ethernet or 10 Gigabit Ethernet. With 1 Gigabit Ethernet, the ports can be equipped with SFP connectors, giving each card a total throughput of 1 Gbps bidirectional. With 10 Gigabit Ethernet, the ports can be equipped with SFP+ connectors, giving each card a total throughput of 10 Gbps.
Each gateway card can optionally be equipped with a JPEG2000 plug-in that enables encoding or decoding of the video while still allowing video to be transported uncompressed. For example, this enables uncompressed transport of SD video while compressing HD signals in order to fit onto a 1 Gigabit Ethernet. With 10 Gigabit Ethernet connectivity, you can have uncompressed transport of up to six SD/HD video signals, or any combinations of uncompressed transport of HD and SD while simultaneously compressing other input signals using JPEG2000.
The Cisco DCM IP Video Gateway has been designed to provide processing of up to 12 video signals. However, the platform is scalable in hardware as well as in software. The chassis can be equipped with one card only, and a basic card always comes with one SD video stream enabled. If the physical configuration is for three inputs and three outputs, the network operator can freely select either to transmit or receive a video stream over IP. The operator can choose over time to enable additional video signals to be processed, as well as to add HD video, Forward Error Correction (FEC) and Hitless Merge (redundancy features described in the next section), and 10 Gigabit Ethernet through software licenses. The capital expenses can therefore be adapted to the existing situation and subsequently to future growth needs.
Redundancy and Reliability
The DCM IP Video Gateway has been designed to allow operators to configure highly reliable networks. The DCM IP Video Gateway supports hot-swappable and redundant power supplies and hot-swappable cooling fans. In addition, each DCM IP Video Gateway Card is also hot-swappable. When the chassis is equipped with two cards, one of the cards can be hot-swapped while the other card continues to operate uninterrupted.
The DCM IP Video Gateway can be configured in a hot 1:1 configuration to support a maximum uptime with minimum switchover interruption.
Each DCM IP Video Gateway card optionally supports a very powerful redundancy mechanism to protect against network failures. The feature is called Hitless Merge, and it relies on dual transmission of the stream in a diverse-path mode. The transmitting DCM IP Video Gateway card provides a copy of the stream on the two Ethernet ports, and the receiving DCM IP Video Gateway card receives the two streams on the two individual Ethernet ports as well. The receiving Gateway card performs a Hitless Merge of the two streams and ensures there is no impact on the outgoing SDI video signal in case of network failures impacting one of the two streams. Hitless Merge is supported with unicast as well as multicast transport.
In applications and networks where dual streaming is not viable, the DCM IP Video Gateway provides forward error correction (FEC) to protect against packet loss.
User Interface and Management
You control the DCM IP Video Gateway through an easy and intuitive GUI. To keep things simple, there is no software to load: the GUI of the DCM IP Video Gateway is a pure HTML-based user interface that can be opened using Microsoft Internet Explorer 6.0 and later or Firefox 3.0 or later. The GUI supports simple program provisioning through drag and drop functionality. The interface provides detailed information, including the DCM IP Video Gateway configuration, input and output video integrity monitoring, and video stream alarms as well as other information.
For integrated network monitoring and control, the DCM IP Video Gateway is integrated with ROSA
® Network Management and Control (NMC) system.
