The station covers around 99% of the country stretching across 11 different time zones
Channel One still has a number of external production companies that produce and deliver on VT — and it will be some time before they are brought into a mindset of tapeless technology.” However, a process of
archiving the more than 70,000 hours of tape to files has begun. Central to that archiving process is a Dalet Media Life system. This core MAM platform at Channel One includes 100 Dalet web clients used for accessing the archive. The archive contains legacy content as well as newly produced content that will be saved into the same central storage as files. Formats that are available include IMX50, XDCAM HD50, and there is a proxy resolution of 2.5Mbps H.264.
The Dalet MAM system
integrates with other systems such as Tektronix Cerify (QC), Harmonic transcoders, and the Grass Valley K2 servers mentioned earlier. It also combines with a Content Storage Management system powered up by DIVArchive from Front Porch Digital. DIVArchive is an open central hub for storing media in multiple formats with a redundancy designed to protect assets. This system assists workflow by providing integration with a range of video devices such as nonlinear editing, MAM, newsroom, traffic and automation systems, and ingest/playout video servers. The DIVArchive system comes with DIVAprotect, which is a constant monitor of the system, gathering detailed information on the movement of content through the file infrastructure, logging statistics, success and failures, and providing a method for proactive content and storage management.
Maintaining control With its domestic output available across so many time zones, the Master Control Room (MCR) operation plays a crucial role in the broadcast chain. Here, transmission controllers for all the channels and time zones share the same room, with identical equipment for each outlet. Vision and audio switching is carried out using Grass Valley Maestro mixers, and TVLogic monitors provide the pictures working alongside Evertz multiviewers. Graphics for all the channels’ output comes from VizRT. Viz Engine is used for rendering
every graphic pixel on air. In order to manage the needs of time zone rebroadcasting, Viz Multichannel has been deployed as a single client that handles the playlist elements of the multiple channels.
Harris D Series automation provides the commands for the Viz Multichannel. Commercials are assembled
by the appropriate department and sent as clips to the automated playout equipment

in the MCR. Located in an area next to the MCR is an array of EVS machines. “These are used in live or near live events,” states Kalanchekaev. “For example, for occasions such as the Olympics, the
channel may wish to replay a particular happening and this can be executed right here in the MCR area. It also enables the channel to place a short delay in replaying a transmission that is coming in from outside, if
