Audio & Video Processing

As a leading expert in audio and video transmission, Beijing Oneband Communication Technology Co., Ltd. has provided industry-leading front-end system solutions based on IP architecture from Harri Company to meet the demands of transmitting audio and video services over telecom links. The introduction and use of this system will elevate digital audio and video transmission to a new level.

【Project Requirements】

Beijing Onebandintong Communication Technology Co., Ltd., a renowned expert in audio and video transmission, offers a digital terrestrial wireless transmission system based on the core products of Harmonic.

The system utilizes the Prostream 1000 stream processing platform produced by Harmonic, which serves as the core processor. It multiplexes, scrambles, shapes, and statistically multiplexes ASI and IP signals, significantly enhancing both usability and advancement for the front end of urban cable networks and terrestrial wireless systems.

DSNG abbreviation－－Digital Satellite News Gathering

Real-time, high-quality internet video streaming at low bit rates is essential to meet the growing demand for internet and mobile devices. The Haivision Promedia™ Live is a real-time video processing and encoding system that utilizes enhanced H.264 video codec technology to create high-quality adaptive bitrate video streams. It can transcode baseband SD and HD MPEG-2 or MPEG-4 AVC (H.264) content for optimized adaptive bitrate transmission of multiple data streams.

The Harrier Promedia 1200 application server supports Promedia Live and Promedia Package software products, which can be deployed separately or integrated into a seamless solution.

The Ellipse®3000 collection encoder leverages Hailey's industry-leading compression technology expertise, with a flexible system architecture that delivers new broadcast-level video quality and operational efficiency contributions. Its versatility in multiple formats and codecs, low latency, and optional integration

The modulator makes this new compressed ideal platform suitable for Digital Satellite News Gathering (DSNG) and fixed contributions. Its compact footprint and plug-and-play deployment offer additional benefits with lower ownership costs.

SmarDTV has launched a dual-slot CableCARD™ and DVB Common Interface chip for use in digital TV receivers. It is suitable for OpenCable™ or Common Interface single-slot or dual-slot designs. The CIMaX™ SP2HF is designed for high-frequency heads and MPEG decoding layers, supporting both serial and parallel bitstream interfaces; it also supports a power-saving standby mode; PQFP 128 package.

With the continuous expansion of HD and the introduction of MPEG-4 AVC, new digital services and the complexity of accelerated deployment have significantly increased the demand for traditional front-end devices. Today's baseband architectures are not equipped to handle this transition smoothly, as content comes from various sources and formats. Furthermore, cable, satellite, and telecom operators are rapidly advancing towards Video-over-IP technology and are seeking the best solution to enable a seamless migration to IP-based services.

The Ellipse 2000 (ELP2000) compact DSNG encoder fully integrates MPEG-2 standard definition 4:2:2/4:2:0 and MPEG-4 AVC high definition 4:2:0 encoders/modulators in a 1RU unit. Designed specifically for digital satellite news gathering applications, the Ellipse 2000 provides professional broadcast-quality encoding and features a built-in DVB-S, DVB-S2, and DVB-DSNG modulator with L-Band and IF outputs. The robust and user-friendly Ellipse 2000 is ideal for mobile satellite news gathering vehicles and flyaway kits operating in the C, Ku, or Ka bands.

Ellipse 1000 is an ideal choice for fixed backhaul applications over IP and traditional ATM/PDH/SDH networks. As a professional, high-quality encoder, the Ellipse 1000 provides effective bitrate utilization for high-quality video transmission. The Ellipse 1000 can encode input video simultaneously in MPEG-2 standard definition 4:2:0/4:2:2 and MPEG-4 AVC standard definition 4:2:0 formats, offering a smooth and cost-effective migration path from MPEG-2 CBR to MPEG-4 AVC CBR encoding methods.
