KDS-EN4 & KDS-DEC4 – Principles of Operation

Principles of Operation

Kramer KDS-EN4 Encoder and KDS-DEC4 Decoder units work in conjunction to provide unicast (one-to-one) or multicast (one-to-many) streaming over an IP network. Using the embedded web pages, you can manage your entire KDS-4 network from a single control unit.

Figure 2: KDS-EN4 & KDS-DEC4 Installation Setup

A Kramer KDS-4 environment is made up of five types of components connected to a network:

• Source – A video source connected to an encoder, for example, a media player, computer, or camera.

• KDS-EN4 Encoder – An encoder is needed for each source. An encoder captures compresses and packetizes the source video, so that it can be transmitted to a single decoder or to multiple decoders.

• Decoder – A decoder is needed for each acceptor. The decoder collects related IP packets from the network, de-compresses them and creates a solid video stream. The user can use KDS-DEC4 or a computer system using VideoLAN® VLC Media Player software as a video player.

• Acceptor – A video acceptor connected to a decoder, for example, a computer, display or projector.

• Control unit – A unit connected to the network that manages video stream routing.

KDS-EN4 & KDS-DEC4 – Technical Specifications

Resetting the Unit

Two types of reset can be performed:

• Reboot – Reboots your unit and keeps all your unit settings, including the IP address and password.

• Factory reset – Reboots your unit and restores all factory settings, including the IP address and password.

Resetting the decoder or encoder can be accomplished by using:

• The Front Panel Reset button.

• Protocol 3000 commands (see System Commands on page 33).

• Web pages – Device Settings Page > General tab (Figure 22)

• Kramer Network

To reset a decoder or encoder unit using the front panel:

• Press and hold the RESET Button with the tip of a paper clip:

▪ For reboot, hold for 2 seconds. ▪ For factory reset, hold for more than 5 seconds.

The device must be powered on when performing a reset.

KDS-EN4 & KDS-DEC4 – Protocol 3000

Protocol 3000

The KDS-EN4 & KDS-DEC4 HD Video Streamer Encoder & Decoder can be operated using the Kramer Protocol 3000 serial commands.

The command framing varies according to how you interface with a device. For example, a basic video input switching command that routes a layer 1 video signal to HDMI out 1 from HDMI input 2 (ROUTE 1,1,2), is entered as follows:

• Terminal communication software, such as Hercules:

The above image is for illustration purposes only.

The framing of the command varies according to the terminal communication software.

You can enter commands directly using terminal communication software (e.g., Hercules) by connecting a PC to the serial or Ethernet port on KDS-EN4 & KDS-DEC4. To enter CR press the Enter key (LF is also sent but is ignored by the command parser).

Commands sent from various non-Kramer controllers (e.g., Crestron) may require special coding for some characters (such as, /X##). For more information, refer to your controller’s documentation.

For more information about:

• Using Protocol 3000 commands, see Understanding Protocol 3000 on page 31

KDS-EN4 & KDS-DEC4 – Protocol 3000

Understanding Protocol 3000

Protocol 3000 commands are structured according to the following:

• Command – A sequence of ASCII letters (A–Z, a–z and -). A command and its parameters must be separated by at least one space.

• Parameters – A sequence of alphanumeric ASCII characters (0–9, A–Z, a–z and some special characters for specific commands). Parameters are separated by commas.

• Message string – Every command entered as part of a message string begins with a message starting character and ends with a message closing character.

A string can contain more than one command. Commands are separated by a pipe (|) character.

• Message starting character:

▪ # – For host command/query ▪ ~ – For device response

• Device address – K-NET Device ID followed by @ (optional, K-NET only)

• Query sign – ? follows some commands to define a query request

• Message closing character:

▪ ␍ – Carriage return for host messages (ASCII 13) ▪ ␍␊ – Carriage return for device messages (ASCII 13) and line-feed (ASCII 10)

• Command chain separator character – Multiple commands can be chained in the same string. Each command is delimited by a pipe character (|). When chaining commands, enter the message starting character and the message closing character only at the beginning and end of the string.

Spaces between parameters or command terms are ignored. Commands in the string do not execute until the closing character is entered. A separate response is sent for every command in the chain.

Kramer Protocol 3000 Syntax

The Kramer Protocol 3000 syntax uses the following delimiters:

• ␍ = Carriage return (ASCII 13 = 0x0D)

• ␊ = Line feed (ASCII 10 = 0x0A)

• ␠ = Space (ASCII 32 = 0x20)

Some commands have short name syntax in addition to long name syntax to enable faster typing. The response is always in long syntax.

The Protocol 3000 syntax is in the following format:

• Host Message Format:

Notes

Relevant only for the decoder. When the video is rendered with artifacts, use this command to add latency to the RTP jitter buffer to allow sufficient time for re-ordering the packet, thereby increasing the video quality. This command sets the network latency expected by the decoder, and not the video latency. However, increasing this value does increase the video latency already inherent in the hardware. To apply changes made with this command, you must send the KDS-ACTION command with the action value as 2 (see KDS-ACTION on page 50).

Parameters

value – scaling mode: 0 (pass-through), 1 (upscale) mode – the display resolution after upscaling:1920x1080p-60

Response Triggers

Notes

This command is relevant only for the decoder. Upscaling display resolution is always 1920x1080p@60Hz. However, if the maximum resolution of the sink is 720p60, the output video will be scaled to that resolution. To apply changes made with this command, you must send the KDS-ACTION command with the action value as 2 (see KDS-ACTION on page 50) and reboot the device.

Response

~nn@KDS-MULTICAST␠group_ip,TTL␍␊

Parameters

group_ip – Multicast group IP used for streaming packets in Multicast Streaming Method, in the following format: xxx.xxx.xxx.xxx. TTL - Time to Live of the streamed packets: 1 (restricted to the same subnet, won't be forwarded by a router), 2–31 (restricted to the same site, organization or department), 32–63 (restricted to the same region), 64–127 (restricted to the same continent), 128–254 (unrestricted in scope)

Response Triggers

Notes

This command is relevant only for the encoder. Multicast groups are identified by special IP addresses between the range of 224.0.0.0 and

239.255.255.255. Addresses within the 224.0.0.0 range are commonly reserved for local subnet communications. TTL (Time To Live) controls the lifetime of the datagram to avoid it being looped forever, due to routing errors. To apply changes made with this command, you must send the KDS-ACTION command with the action value as 2 (see KDS-ACTION on page 50).

Example

Set the group address to 224.0.0.0 and the TTL to 1: #KDS-MULTICAST 224.0.0.0,1<CR>
