Ikegami announces UHK-X700RF wireless television camera
Ikegami has expanded its UNICAM-XE camera line-up with the launch of the UHK-X700RF, a wireless portable camera that retains the core features, ergonomics and lightweight design of its wired counterpart, the UHK-X700. Designed to meet the demands of modern broadcast production, the UHK-X700RF offers broadcasters increased creative freedom across a range of applications, from live news and sports to stage and studio events.
Gisbert Hochguertel, Ikegami Europe Product Specialist, said: 'UNICAM-XE series cameras are designed to allow fast and easy setup, versatile operation and secure delivery of broadcast quality video. They share the robust build quality and intuitive control structure that have made Ikegami UNICAM camera systems a popular choice among television control producers in Europe and around the world. The UHK-X700RF opens a wide vista of creative perspectives for applications such as news, OB sports and coverage of stage events. Even in fully rehearsed studio projects, it offers producers the freedom to introduce unusual-angle shots at short notice.'
The UHK-X700RF is powered by a native 4K UHD sensor with 3840 x 2160 resolution and global shutter technology, ensuring clear, natural images under various lighting conditions. It supports both UHD (2160p at 50/59.94 fps) and HD (1080p/i at 50/59.94 fps) video formats. Like other models in the UNICAM-XE family, it includes a dual filter wheel for independent light and colour control, plus space for effect filters or optical low-pass filters to reduce moiré and aliasing. It also offers automatic vignetting correction when used with OVC-compatible B4-mount zoom lenses.
The camera's wireless transmitter operates within the 2 to 2.7 GHz range, tunable in 250 kHz steps, with a 100 mW output. It features two antennas, one for video and another for telemetry, and uses multichannel antenna diversity for strong signal stability across a 500-metre transmission range. For extended coverage, up to 22 IP-Mesh data transceivers can be integrated into a single system. The camera delivers ultra-low latency encoding at just 40 milliseconds for both UHD and HD formats.
The system's receiver and decoder unit fits a half-width 19-inch rack and supports DVB-T modulation in QPSK, 16QAM and 64QAM, with adjustable bandwidths from 5 to 8 MHz. To ensure robust performance under various conditions, the DVB-T guard interval and forward error correction settings are user-configurable. The unit accommodates multiple video codecs including H.265-HEVC, H.264-AVC, and MPEG-2, and supports all common HD and UHD broadcast frame rates in SDR, HDR (BT.2100), and BT.2020 wide color gamut formats.
The receiver features four SDI outputs (1.5G, 3G, and 12G) with embedded audio, two XLR analog audio outputs, a genlock BNC input, and a 12V DC XLR power input. It can connect directly to up to eight downconverters via BNC cables, supporting cable lengths up to 100 meters. To increase distance between receiving antennas and the Sapphire-RXD4, users can utilise a fibre base unit and extension module connected via SMPTE hybrid fibre/copper cables with LEMO connectors—offering an extension range of up to 1 km with power supplied through the same cable.
With the UHK-X700RF, Ikegami continues to push the boundaries of live production technology, offering a robust and flexible wireless camera system tailored for today's fast-paced broadcasting environments.

Striking Boeing defense workers turn to US Congress
"We respectfully ask you to join us in supporting this vitally important, highly skilled workforce," the machinist union said in letters to the Missouri congressional delegation, describing Boeing's latest offer as "substandard." Some 3,200 members of the International Association of Machinists & Aerospace Workers District 837 have been on strike since August 4 after rejecting a contract proposal. The two sides have not held talks since the walkout, representatives of both sides said. The strike affects Boeing facilities in St. Louis and St. Charles, Missouri and Mascoutah, Illinois. "We ask you to urge the Boeing Company to promptly return to the bargaining table with new ideas and proposals in order to seek a fair and equitable settlement to this disagreement," said a letter signed by IAM International President Brian Bryant. Products produced at the affected sites include the F-15 and F-18 combat aircraft, the T-7 Red Hawk Advanced Pilot Training System and the MQ-25 unmanned aircraft. Prioirties for the union include fair compensation, with wages that meet the cost of living and "a contract that respects seniority and experience," the IAM said. Boeing said its offer includes 40 percent average wage increases, as well as more vacation and sick leave. "We're surprised to hear the IAM International call our offer 'substandard' after hailing it as a 'landmark' agreement which they endorsed just three weeks ago," said Boeing Air Dominance vice president Dan Gillian. "We remain ready and willing to listen to any constructive proposals from the union." The St. Louis local's stoppage follows a bruising Boeing strike last fall in the Pacific Northwest region of some 33,000 workers that halted production at factories that assemble Boeing commercial planes. Boeing executives have characterized the St. Louis strike as manageable, noting that they had prepared for a stoppage before the workers joined the pickets.

AT&T considers selling-off its Mexican business
AT&T has met with advisors to sell-off its mobile business in Mexico for more than $2 billion after competing against billionaire Carlos Slim for years. Bloomberg reported discussions are ongoing as a final decision is yet to be made. It also stated there's no guarantee AT&T will find a buyer. A representative for AT&T told Mobile World Live the company does not comment on rumours or speculation. In 2014, AT&T paid $2.5 billion to buy Mexican mobile operator Iusacell from Grupo Salinas and then announced a $1.9 billion deal to acquire the Mexican business of NII Holdings a year later. The news agency stated AT&T has about 18 per cent of the mobile market share in Mexico, compared to Telcel's 64 per cent. Telcel is part of Mexico-based America Movil which is controlled by Slim and his family. Bloomberg noted AT&T has invested more than $10 billion in Mexico. As of December 2024, it had more than 23 million total subscribers. During last month's Q2 earnings, the mobile operator reported revenue in its Latin America division was down 4.4 per cent year-over-year to $1 billion. Source: Mobile World Live Image Credit: AT&T
