BVMS – Technical RECAP Cameras
Foundations: H.264
 All current available Bosch IP encoders and cameras encode video in H.264 format.
 H.264 / MPEG-4-Part 10 / MPEG-4-AVC (ISO/IEC 14496-10)
are common names for the same video compression standard.
 H.264 is the most widely used video compression nowadays.
The successor of H.264 is H.265:
 HEVC stands for High Efficiency Video Coding
 A lot of Bosch cameras support also H.265. The “I” at the end
of the product name is an indicator for H.265 support. e.g. Flexidome IP 5000i

BVMS – Technical RECAP Cameras
Foundations: H.264 Compression
 Why is compression needed?
 If no compression is used, the bandwidth would be approx. 216 Mbit/s. This means that a normal DVD (8GB)
would only hold about 5 minutes of video.
JPEG: Each frame is completely encoded
H.264: Frame 1 and 5 are I-frames.
Frames 2,3,4 are P-frames.

BVMS – Technical RECAP Cameras
Foundations: Group Of Pictures (GOP)
 H.264 based IP Video is encoded in a GOP. The GOP can consist of up to three types on frames:
 I-Frame: An intra-frame is the reference (full) frame
(or anchor) frame. All GOP’s start with an I-frame.
 P-Frame: A predicted frame is coded with respect
to the nearest previous I-(or P) frame.
 B-Frame: Bi-directional predictive frames use both
past and future frames for reference
(B-frames are never used as a reference).

BVMS – Technical RECAP Cameras
Foundations: Group Of Pictures (GOP) – B-frames
GOP is a Group Of Pictures that starts with an
I-Frame and ends before the next I-Frame comes.
I-Frame distance shows how many frames is the GOP
made of. I-Frame distance 10 = 9 P&B-Frames + 1 I-Frame
i.e. every 10th frame is an I-Frame.
…
B I B P B P B P B P B I B P B …
GOP generated by an encoder with structure IBP and I-Frame distance 10
 B-Frames reduce bandwidth and storage usage as they are smaller in size than P-Frames.
 B-Frames in the GOP structure IBP and IBBP
were introduced in BVMS9.0 besides of the
IP structure.
 B-Frames have references to previous (frames generated before the B-Frame) and to following frames
(frames which will be generated after the B-Frame)
 Question: Is there an impact on a Live Stream of a camera when using a GOP structure with B-Frames?

Foundations: Video Quality in general
 When planning a IP Video project you have to consider three important things:
‒ Number of channels (camera, encoders)
‒ Bandwidth of each camera
‒ Storage (most expensive part)
 Resolution + Frames per Second (FPS or IPS) equals Bandwidth generated
 Bandwidth is the main factor influencing Storage demand for recording and viewing quality!

Networking: Multicast deployment
Multicast Streaming
What to consider when deploying a Multicast capable network environment?
 Specifications of switches: IGMP protocol support ? Internet Group Management Protocol is required to manage the multicast
groups https://en.wikipedia.org/wiki/Internet_Group_Management_Protocol
 Specifications of switches: How many IGMP groups are supported? Each camera stream is one multicast group.
Two streams of a camera requires 2 multicast groups on the switch.
 When deploying several switches it may ease the later troubleshooting when choosing the same switch vendor for all
 Skilled network staff for the initial setup and later troubleshooting is required

BVMS – Technical RECAP Cameras
Fundamentals: Streaming
Unicast
Maximum 5 Streams in parallel
All Bosch encoders and cameras have configurable streams:
 Availability of streaming options varies depending on product family (Check out the data sheet!)
 Unicast is limited to 5 Clients (e.g. BVMS Operator Clients) in parallel which can get simultaneously a
stream from the camera.
 Design Advice: More than 5 Clients need to see a live stream from a camera in parallel?
 Go for Multicast!
 Only one type of multicasting is supported in BVMS: On-request (RCP+ Back Channel to every camera)
 H.264 Stream 1 and Stream 2 of the camera can be configured independently for BVMS usage.
Example: Stream 1: 1080p Resolution with 30FPS and Stream 2: 1080p with 15FPS => 2 Encoders of the
camera are utilized. 3rd Stream “Type” e.g. 720p with 30fps is not possible at the same time.
