Airtel Digital TV Deploys Harmonic Headend To Improve HD Quality And Reduce Costs
Airtel Digital TV, the direct-to-home arm of Bharti Airtel, has deployed a compression headend solution from Harmonic to increase bandwidth efficiencies and significantly improve HD video quality while lowering operating expenses and total cost of ownership. The deployment enables Airtel Digital TV to expand its high-definition portfolio to over 50 premium channels, making it one of the largest HD bouquets in India today.
At the heart of the headend solution is Harmonic's Electra X2 advanced media processor, which enables high-quality, low-bandwidth MPEG-2 and MPEG-4 encoding of SD and HD video content for live DTH services. Powered by the Harmonic PURE Compression Engine, the Electra X2 media processors support a wide range of video formats and codecs for satellite delivery, including HEVC. This simplifies operations and future upgrades for Bharti Airtel, the companies note.
The Electra X2 media processors will be integrated with Harmonic's ProStream 9100 stream processor and ProView 7100 integrated receiver-decoder (IRD) at Airtel Digital TV. This solution is controlled by Harmonic's NMX video network management solution. The new headend caters for decoding, descrambling and multiplexing of multiple transport streams, MPEG-4 to MPEG-2 transcoding and statistical multiplexing.
"Harmonic's compression solution allows Airtel Digital TV to deliver superior video quality at low bit rates while adapting to next-generation video compression standards such as HEVC," explains Dan Taylor, General Manager, India, at Harmonic. "Our video infrastructure solutions help customers like Airtel Digital TV reduce OpEx and drive new business growth by simplifying the launch of additional HD channels."
