汤姆森 视频网络 today introduced a significant new capability for its state-of-the-art statistical multiplexing technology, Flextream 2.0. 现在，Flextream 2.0 has the ability to integrate variable bit-rate data streams within the video pool. The benefits are immediate: whenever the data bit-rate decreases, Flextream 2.0 automatically reallocates the freed bandwidth to the video to optimize bit-rate usage within a multiplex.
汤姆森 视频网络' statistical multiplexing technology automatically controls the company's ViBE MPEG-2/4 SD or HD encoders by dynamically allocating video bit-rates according to quality targets and service priorities. 以这种方式, it significantly optimizes bandwidth utilization and improves the resulting video quality, which is a continuous requirement for 卫星 Direct-to-首页, 地面或有线网络. Flextream 2.0 extends this technology to intermittent data streams; instead of reserving a fixed amount of bandwidth within the multiplex for passing these streams, Flextream 2.0 dynamically adapts the video pool bit-rate based on the quantity of data to be transmitted, 不超过预定义的阈值. Ideal for asynchronous data components or services, Flextream 2.0 offers a cost-effective and safe solution for broadcasting EMM, EPG, and interactive applications such as HbbTV (Hybrid Broadcast Broadband TV), 系统软件更新, 播放视频点播节目.
Flextream 2.0 applies a complementary approach to Opportunistic Data Insertion (ODI). Instead of adapting the data bit-rate to the audio/video services, it adapts the video pool bit-rate to the amount of data to broadcast (不超过预定义的阈值). It also comes with monitoring utilities that notify operators when the data streams exceed their maximum allowed bit-rate.
因为Flextream 2.0 reallocates every unused data packet to video transmission, it optimizes the usage of the bandwidth within a multiplex and improves the overall perceived video quality whatever the encoding format, 包括MPEG-2/4. 因此，Flextream 2.0 technology now allows operators to take advantage of every packet of a multiplex for conveying data or video. It also simplifies the operational workflow; for example, it's no longer necessary to modify multiplex configurations each time there's a need to broadcast a higher amount of data, 比如隔夜的传输. Instead, the system automatically adapts to real-time conditions.
"Flextream 2.0 is the latest example of 汤姆森 视频网络' ongoing innovation in compression and multiplexing technology, demonstrating our commitment to offering the most cost-effective solutions and delivering the highest video quality,埃里克·加利尔说, vice president of marketing at 汤姆森 视频网络.
Flextream 2.0 is available as a software option for 汤姆森 视频网络' NetProcessor video processing equipment, as well as the company's ViBE EM series of broadcast encoders. Flextream 2.0 can also be deployed easily on existing 汤姆森 headend platforms.
