Harmonic, Motorola tout their respective IRDs/transcoders
Harmonic announced it is bringing its video compression tech to the integrated receiver-decoder (IRD) market with the introduction of the ProView 7100, while Motorola Mobility has introduced a family of combo IRD-transcoders.
The next-generation, multi-function ProView 7100 provides transcoding, transport stream descrambling and MPEG stream processing in a single rack unit. The IRD’s SD and HD MPEG-2 and MPEG-4 AVC video decoders and transcoders allow content providers, broadcasters, MSOs and telcos to address a wide range of full transport stream distribution and contribution applications, including DVB descrambling and digital turnaround processing.
The ProView 7100 performs multi-format video decoding with up to four stereo pairs of audio decoding, descrambles up to four transport streams and transcodes up to eight channels.
"The flexible, high-density multichannel solution allows users to deploy an IP headend easily and cost-effectively and launch added-value services such as HD and video-on-demand with excellent video quality," said Tom Lattie, vice president of product management at Harmonic.
Meanwhile, Motorola’s combo IRD-transcoders are designed to accept satellite video encoded in MPEG-4 and immediately transcode that video into MPEG-2, which is still more commonly used than MPEG-4 in many cable systems.
Motorola Mobility’s DSR-6400 family combines traditional IRD functions and transcoding functions into a single rack unit. The family includes single-, dual-, three- and four-channel configurations; each channel can independently transcode the input MPEG-4 HD video service into simultaneous MPEG-2 SD and HD video outputs.
Once the operation has shifted internally to MPEG-4, the 6400s remain in place, simply passing through MPEG-4 video.
Two members of the 6400 family have additional features. The DSR-6403 and DSR-6304 support a closed-loop statmux capability to maximize transmission bandwidth efficiency.
The DSR-6404 can be provisioned for constant bit rate (CBR) and variable bit rate (VBR) video encoding, allowing for high-quality video statmux in groups with up to four HD channels within a 256-QAM multiplex bit rate of 38.8 Mbps, Motorola said.
The DSR-6400 also utilizes AFD (Active Format Descriptor) to translate input HD services to an appropriate SD service with proper aspect ratio and resolution, ensuring that video is display-ready for screens of any size and format.
Bomar intros BNC E-Snap coax connector
Bomar Interconnect Products has expanded its E-Snap Series of edgeboard RF connectors to include the vertical or horizontal mount BNC E-Snap coax connector.
Developed for use with PCMICA cards in wireless applications, Bomar's BNC E-Snap connectors are the latest addition to the 50-ohm E-Snap Series. The miniature, lightweight construction promotes board retention and RF performance without the use of adhesives. And parts are engineered with small protrusions within their slots to allow devices to "snap" firmly into solder-pasted holes as they are slid onto the PC board.
Bomar's newest BNC coax connector is intended for use in a wide array of wireless applications and is suited for dense packaging arrangements where mechanical strength, high durability, high reliability and low VSWR are required. Devices accommodate a large variety of RG and industry-standard cables.
The E-Snap Series boasts a straight-through contact design, and the connectors feature gold-plated contacts. The series provides repeatable performance to 18 GHz standard, while high-frequency versions may be ordered with repeatable performance to 20 GHz.
Parts are supplied in male or female versions and are offered in standard and custom-plating alternatives.
Distributor pricing for Bomar’s vertical or horizontal mount BNC E-Snap edgeboard RF connectors starts at $4.59 each in quantities of 1,000.
