多摄像头体育网络广播与NDI和TriCaster TC1

我们真的很喜欢我们的运动，不是吗? 我们怎么也看不够. 我们把季节和我们参加的比赛联系在一起. We have game-day food that we always eat when watching at home. If we can’t watch, we’re sure to keep checking the live scores on our phones.

有些人更喜欢现场游戏的体验. I clearly remember attending Atlanta Braves games at Fulton County Stadium and later Turner Field with my parents back in the ’90s when the “dream team” was in the playoffs every season. 就像我们走进走廊去找座位一样, 球迷们安静的吼声会慢慢变大, and the otherworldly b正确的 lights would make the players’ white uniforms stand out against the fresh-cut, 翠绿的田野. The smells and the sounds made for a memorable experience that is unrivaled.

But for many, watching at home is the only way to go for enjoying sports. 环绕声系统, 高清或4K广播, and being closer than otherwise possible to the action make the parking hassle, 昂贵的食物, 和小, 不舒服的体育场座位很容易让人抗拒. Now we can watch hockey and golf and know exactly where the pucks and dimpled balls are at all times. It’s simply much cheaper to enjoy sports from the living room rather than the stadium, 而且观看质量也在不断提高.

The NewTek TriCaster has been a favorite option for live sports production for years, 以及2017年在拉斯维加斯举行的NAB展会, 新科技推出TriCaster TC1 (下面的图1). The TC1 offers 4K 60P (SMPTE 2036 UHDTV1) recording and broadcasting. 起价15美元,000, it’s one of the most affordable professional UHD broadcasting solutions on the market. With 16 SDI inputs, it’s sure to handle any multicam production you can throw at it. 但TC1的摄影技巧还不止于此. It also supports NewTek’s own Network Device Interface (NDI) technology, 它允许一连串的设备通过IP连接到TC1. Combining NDI cameras with SDI sources can give you more angles than you can shake a hockey stick at.

即时重放

Those familiar with TriCaster systems have likely heard of NewTek’s 3Play instant replay hardware (下面的图2). Since instant replay is practically expected in any sports production today, TC1提供了一个内置的即时回放系统. The 60-frame recording provides silky smooth replays that can be scrubbed at multiple speeds from a DDR. The differentiation between the built-in replay of the TC1 and the dedicated replay system of 3Play primarily lies in versatility.

NewTek’s Chris Burgos explained the TC1 replay system this way: “The replay functions of the TC1 allow for a user to cut simple replay clips in production. Once the replay feature is enabled and the DDR of choice is selected, the user can click the channel of record they want to replay and it will create a growing file in the DDR. 该文件可以转换为, and it will play out a clip of a preset length and then transition back to gameplay. 因为文件在变大, the user can change its in point and out point to adjust for a better fitting replay, DDR文件可以在直播前预览. The angle can be selected (as long as the camera was coming directly to the TC1), and the replay trigger takes you a number of seconds back in time. This workflow is simple and designed for teams without the resources for full replay capabilities.”

Sounds great for high school sports or smaller colleges and universities with limited budgets and staff, 正确的? 以下是专为3Play网制作的弹簧, according to Burgos: “3Play is a full-scale replay solution that allows for users to quickly cut multi-angle replays, 回放高光片段, 启用慢动作和倒转功能, 全部来自一个单元. 3Play allows for operators to adhere to broadcast styles of workflow and playout and even has a dedicated control surface to help for its specific purpose.”
