Hitachi Information & Telecommunication Engineering, Ltd.

Receiving a maximum of 16 TSs, changing channels, and QAM modulation are all integrated in one device. The UM7000 contributes to reduced equipment costs and improved reliability by applying redundant configurations.


Functionality and Features

Output of a maximum 16 64-QAM channels

The UM7000 can receive a maximum 16 TSs over IP networks, and output them after 64-QAM modulation. You can specify independent frequencies for each of the 16 TSs.

Enables individual channel planning at each sub headends

NIT*3 edit function enables flexible operation of channel planning. UM7000 at sub headends can output 64-QAM signals in different frequency to master headend.

Supporting TSMF*4 transmission

The UM7000 can directly transmit TSMF-format signals widely used in CATVs (in Japan) It also supports IP transmission for digital terrestrial/satellite TV signals.

Redundant configuration for high-reliability operations

UM7000C (RF*5), a signal switching device , enables automated switch-over in redundant configurations.

Achieving IP-based video transmission between cable TV stations

Achieving IP-based video transmission between cable TV stations

  1. This is a conceptual example. Actual configuration may vary to meet real applications.
  2. A media converter, network device, or other items might be required separately.

TS (Transport Stream): TS is one of the standard transmission formats used for digital broadcasts in various countries, including digital terrestrial TV and DTH (digital sattelite TV) used in Japan. TS signal enables video and audio to be transmitted as a single transmission stream.
QAM (Quadrature Amplitude Modulation): QAM is a modulation scheme for changing digital data to waves.
NIT (Network Information Table): NIT is digital information included in broadcast waves that contain channel frequency used by a broadcast station.
TSMF (Transport Streams Multiplexing Frames): TSMF is a signal format used in Japanese CATV for efficient re-transmission of digital terrestrial/satellite broadcasts.
RF (Radio Frequency): RF is a high frequency wave used for video and audio of TV broadcast.
