Target settings
This product can transmit encoded video and audio to an IP network and record them to a storage medium by configuring the target (streaming destination) settings. The target settings can be configured using LiveShell Studio. The target setting cannot be set using the main unit.
Overview of target settings
Target refers to the destination of the video and audio streams generated by this product's encoder, and can be broadly classified into two categories: network distribution and recording.
This product can send the same stream to up to three targets simultaneously. Therefore, this product can hold up to three different target settings that are active at any given time. On the other hand, there is no limit to the total number of target settings this product can store. For example, if there are seven targets stored in this product as shown in the figure below, any three of the seven targets can be enabled as the targets to be actually used. The enabled targets are specifically called "Channel".

Protocols available for live streaming network
The application protocols that can be used for live streaming network are as follows;
RTMP and RTMPS
RTMP and RTMPS are protocols used to send video and audio to the major live streaming platforms. RTMP sends the stream in plain text, whereas RTMPS encrypts using the Transport Security Layer. Some platforms specify to use RTMPS.
In general, doing live streaming via RTMP or RTMPS, an account must be issued by the live streaming platform, and an RTMP URL and stream key must be obtained. In addition, the recommended settings for the encoder etc, may vary depending on the streaming platform. Check these settings as well before configuring the device.
RTSP server mode
RTSP is a function for this product to act as a server and stream video and audio to connected clients. This protocol is suitable for use in local networks, such as viewing to check program output and live streaming within premises.
MPEG2-TS over UDP
MPEG2-TS over UDP is a mode in which multiplexed video and audio as MPEG2 Transport Stream are sent out as payload of UDP datagrams without any procedure. This protocol is suitable for video transmission to a video decoder or other device that can receive this protocol.
Stream recording
You can also set "recording" as one of the live streaming targets. In this case, the stream is recorded to the storage media attached to this product in MP4 container or MPEG2-TS format. The media that can be used as the recording target are as follows;
SD card
The recording target is the micro SD card inserted into the SD card slot of the main unit. A microSD card must be SD, SDHC, SDXC cards formatted in FAT32 or exFAT format.
USB Drive
A USB drive connected to the USB port on the unit is used as the recording target. The supported USB drive must be a mass storage device with a maximum capacity formatted in FAT32 or exFAT format.
