爱立信，英国电信展示前沿HEVC 4K直播技术
新德里: 2016年荷兰阿姆斯特丹广播电视设备展览会（IBC）上,爱立信,英国电信媒体和广播台，以及英国电信体育台借助交付4K超高清晰度电视
(UHDTV)首次展示了他们在高效视频编码(HEVC)方面的成果。
英格兰橄榄球超级联赛第2轮期间，英国电信体育台将通过使用高性能单片HEVC连接进行4K超高清晰度电视的交付(UHDTV)的球赛直播。直播将使用英国电信的新型直播车。
英国电信媒体和广播(BT M&B)与爱立信一同展示了UHDTV的内容是如何在没有任何信号缝合的情况下，通过单一信号发送的。爱立信的新编码/解码技术支持HEVC，在简化基于UHDTV的复杂AVC象限上取得了突破。
这项技术为电视服务提供商，在更大的网络带宽使用情况方面节省了高达40%的效率,它只需要使用一个编码器/接收器就能提供最佳的图像质量。
BT M&B将信号传送给爱立信位于阿姆斯特丹希尔弗瑟姆的播出中心，爱立信 (#1.D61)和BT M&B(O.C01)位于RAI阿姆斯特丹大会中心外围展区的展位将同时直播比赛实况。
爱立信和英国电信在共同合作UHDTV项目上深有渊源。追溯到2013年，爱立信和英国电信成功创造出了世界首例可供体育赛事使用的多摄像机模式产品，直播时使用AVC以达到4:2:2,10位分辨率,4K UHDTV信号以及60帧每秒的速度。去年，爱立信和BT Sport宣布将携手推出英国首个UHDTV频道。
Elisabetta Romano，爱立信的副总裁及电视媒体部门主管表示：“该演示很好的证明了我们使用单一信号传递所有的视频内容，能够提供高质量、操作便捷和高效率的宽带服务，从而在UHDTV交互方面产生更大的成本效益。这时UHDTV的一个转折点，使得4K直播体育赛事和重大事件更具可行性，首次实现低成本和高质量同在。”
BT M&B副总裁Mark Wilson-Dunn表示：“新设备和新UHD直播车的组合将为今年的观众带来无与伦比的高质量赛事直播。我期待着大家共同分享创新成果,以及如何与IBC其他行业人士一同为用户提供更好的服务。”
Ericsson, BT showcase cutting edge live HEVC 4K broadcast at IBC 2016
NEW DELHI: At IBC 2016, Ericsson, BT Media and Broadcast and BT Sport will showcase their first-ever live demonstration of
a high efficiency video coding (HEVC) contribution link used in the delivery of 4K ultra-high definition television
(UHDTV).
The high performance single-slice HEVC link will be used to broadcast live rugby matches on BT Sport in 4K ultra-high definition during Round 2 of the AVIVA Premiership. The broadcast will be delivered using BT’s new links truck.
Together with Ericsson, BT Media and Broadcast (BT M&B) is showing how UHDTV content can be broadcast through one single slice, without any signal stitching. Ericsson’s new encoding/decoding technology supports HEVC and removes the need for complex AVC quadrant based UHDTV contribution.
This technique offers TV service providers savings of up to 40 percent on bandwidth usage with far greater network efficiencies, as it only requires the use of one encoder/receiver to deliver optimal picture quality.
BT M&B will deliver the signal to Ericsson’s Playout Centre in Hilversum, Netherlands, and Ericsson will broadcast the rugby matches live and direct to Ericsson’s booth at IBC 2016 (#1.D61), as well as to BT M&B’s booth (O.C01), located in the outside exhibition area at the RAI Amsterdam Convention Centre.
Ericsson and BT have a strong history of working together with leadership in UHDTV. Back in 2013, Ericsson and BT also produced the world’s first multi-camera production of a sporting event, displaying it live in a 4:2:2, 10-bit resolution, 4K UHDTV signal at 60 frames per second using AVC. Last year, Ericsson and BT Sport announced that they would work together to launch the UK’s first UHDTV channel.
Elisabetta Romano, Vice President and Head of TV and Media, Ericsson, says: “This demonstration shows we can drive better quality, operational simplicity and bandwidth efficiency, giving far greater cost-efficiencies in UHDTV delivery by contributing all the video content in a single slice. This is a turning point in UHDTV, making 4K live sports and events a practical, cost-effective and high-quality reality for the first time.”
Mark Wilson-Dunn, Vice President at BT M&B, says: “The combination of the new equipment with our new UHD links truck will deliver unbeatable high-quality sports footage to viewers at this year’s event. I’m looking forward to sharing our joint innovation and how we’re delivering an even better service to our customers with the rest of the industry at IBC.”
