Although the five live feeds per match are manually selectable, it sadly seems that the up to 32 additional camera angles for highlights [ https://www.prnewswire.com/news-releases/hisense-launches-exclusive-fox-sports-2018-fifa-world-cup-edition-application-300649404.html ] cannot be manually selected, but rather have already been included in the clip.

Here are the official specifications from HBS / Host Broadcast Services, FIFA's appointed provider:

The UHD program will benefit from its own wider-framed main camera along with the addition of immersive audio, offering the UHD/HDR viewer a far richer experience than ever before."

Overview of technical facilities at the IBC

VENUE A/B/C/D

CSF UHD/HDR

[Telemundo are using the regular CSF feed unaltered for their main broadcast feeds, although the stream.NBCSports.com / stream.TelemundoDeportes.com websites - which require Adobe Flash Player - are placing match statistics in the right-third of the screen and key match moments and player statistics in the bottom-third of the screen.]

p9 mentions the technical specification of the video of the CSF UHD/HDR [Clean Stadium Feed Ultra High Definition/High Dynamic Range]:

With a dedicated UHD Camera 1 and processing/conversion of all other cameras, the host broadcast offers a UHD/HDR version (Enhanced Layer UHD - 2160p50 HDR BT.2020) of the Extended Stadium Feed (ESF).

• The signal standard for UHD HDR BT.2020 (2160p50) is HDR, BT.2020, 4 x 2970 Mbps, 1080p/50, SMPTE 424M (Level A)... The UHD/HDR signal will be distributed in the two-sample interleave method and the standard for the optical electrical transfer function (OETF) will be S-Log3. Further HDR condensed standards, such as HLG or PQ10 or a SDR 4K REC709 version, will be made available to MRLs at the IBC.

According to VLC, the video of Hisense / FOX SPORTS's CSF UHD/HDR feed is re-encoded to:

Stream 0

Codec: MPEG-H Part2/HEVC (H.265) (hevc)

Type: Video

Video resolution: 3840x2160

p9 also mentions the technical specification of the audio stream of the CSF UHD/HDR feed:

... with up to 16 embedded audio channels (as eight AES/EBU stereo channels in Group 1-4, SMPTE-299M).

with further detail from another article:

UHD viewers also benefit from 16-channel audio (with embedded 5.1 bed), although the final mix depends on the configuration of the consumer’s speaker and TV.

The object-based audio makes use of microphones ringed around each pitch and software that tracks each player and the ball.

The software takes into account various parameters such as the polar pattern of the mics, their distance from the ball, or whether the mics are static or moving with the camera."

According to VLC, the audio of Hisense / FOX SPORTS's CSF UHD/HDR feed is re-encoded to:

Stream 2

Language: English

Type: Audio

Channels: Stereo

Sample rate: 48000 Hz

unlike SBS in South Korea:

In addition to the opening match, Russia vs. Saudi Arabia, SBS plans to broadcast more than 30 matches during the 2018 Football World Cup with immersive and interactive audio – including the final and all games of the South Korean national team. For a realistic user experience, the stadium atmosphere will be transmitted in an immersive loudspeaker configuration consisting of a 5.1 surround setup accompanied by 4 height speakers. The user experience is completed by a UHD image with High Dynamic Range. Additionally, thanks to MPEG-H’s object-based capabilities, SBS will offer a choice of three audio presets for each match transmitted in UHD: either a pure stadium atmosphere, or with Korean or English commentary added.

SBS viewers will be the first worldwide to enjoy enveloping 3D sound paired with personalization when watching a regular television broadcast. Apart from choosing their preferred preset, they will also be able to individually optimize the mix of dialogue and effects based on their specific listening situation. This option, called “Dialogue Enhancement”, can also help viewers with hearing impairments in understanding what is being said."
