Technical Overview
BLANKOM IRD-6310 / IRD-6311 combines 1 RF tuner with ASI and IP reception, conditional-access processing and one HD/SD video decoder. It receives transport streams, selects the required service and delivers decoded video to SDI, HDMI and CVBS while retaining ASI/IP transport-stream outputs. More tuner inputs increase reception flexibility; they do not mean multiple independent video decoders.
The supported video formats include MPEG-2, AVC/H.264 and HEVC/H.265 with 4:2:0 sampling. Two independent CI slots accept compatible CAM modules; BISS-1/BISS-E is also specified. The two SDI connectors are mirrored outputs. The selected tuner hardware must match satellite or the required cable/terrestrial/regional broadcast standard.
The model difference is audio: IRD-6310 provides two stereo audio channels, whereas IRD-6311 provides one. The IP output is specified as one MPTS and 16 SPTS over Gigabit Ethernet. Configuration uses the front-panel LCD/buttons or built-in Web management; redundant dual power is optional.
Typical Applications
Broadcast and production reception
Receive the selected broadcast or IP service and decode it to SDI for a compatible production chain. HDMI or CVBS can provide local monitoring; the destination must support the selected picture and audio format.
Hybrid ASI/IP headend
Receive services from RF, ASI or IP and route the configured transport stream to ASI/IP equipment. Plan service selection, conditional access, programme identifiers and aggregate bitrate together.
Programme monitoring and audio selection
Monitor a selected TV service while using the stereo audio capacity required by the installation. Choose IRD-6310 for two stereo channels or IRD-6311 for one; tuner count and video decoding capacity remain separate selection criteria.

Engineering FAQ
How many RF tuners are fitted?
The IRD-6310 / IRD-6311 family has 1 RF tuner. Select the reception standard as part of the hardware configuration.
What differs between IRD-6310 and IRD-6311?
IRD-6310 provides two stereo audio channels; IRD-6311 provides one. The documented main reception and video features are otherwise shared.
Which additional transport inputs are available?
Two ASI inputs and 16 UDP/RTP/RTSP IP input streams are listed. Match the source stream format and aggregate bitrate to the receiving configuration.
How many video programmes can be decoded?
The technical table lists one video decoding channel. Tuner count, CAM count and IP service count do not multiply the number of decoded pictures.
Which video codecs are supported?
MPEG-2, MPEG-4 AVC/H.264 and HEVC/H.265 HD/SD decoding are specified. Confirm the source profile, resolution and frame rate against the technical table.
Are the two SDI outputs independent?
SDI1 and SDI2 are mirrored outputs of the selected decoded service. They do not provide two independently selected video programmes.
What can be delivered through IP?
The output specification lists one MPTS and 16 SPTS through Gigabit Ethernet, using UDP/RTP unicast or multicast and RTSP as documented.
How are encrypted services handled?
Two independent CI slots support compatible CAM modules. BISS-1/BISS-E descrambling is also specified; access rights and correct keys/modules are required.
Which audio and monitoring interfaces can be used?
HDMI, SDI and the specified audio connection or adapter configuration serve the installation. Multi-channel AC-3 output noted for HDMI/SDI must not be assumed for analogue stereo connectors.
How is the unit operated and is redundant power included?
Use the LCD/keypad or Web management. Redundant dual power supply is optional and must be included in the ordered configuration.
