We do not support shipping items in a single order to multiple shipping addresses. To ship items to an additional address, please place a new order to us. Unless otherwise specified, delivery charge at the rate of HK$300 will be imposed on each delivery. We currently offer free delivery for each order over HK$1,000.

For international shipping please contact our sales team via email - sales@chinam.com.hk

Deliver Time

  • Once your order has been handed over to the carrier for delivery, you will receive a shipment notification email with an estimated delivery date. Please note that it is not possible to expedite your delivery and receive your package earlier than the scheduled delivery date. Therefore, we are unable to accept requests for expedited delivery. Our carriers are unable to provide an exact time of day for your delivery. If you ordered multiple items, you may receive separate shipments.
  • All estimates are based on business days. We only make deliveries in the specified areas of Hong Kong from Monday to Sunday except on the first two days of the Lunar New Year and when typhoon warning signal No. 8 or above or black rainstorm warning is in force.
  • All rescheduling of delivery, additional purchases, new sales memos and amendments must be made 3 days before the scheduled delivery date. Otherwise, a double delivery charge will be incurred.
  • We may deliver the merchandise in one or more installments, and some of the merchandises may be delivered directly from suppliers. Any times and dates given for dispatch of merchandise, or the length of time that merchandise will take to be delivered, are only estimates. If we are unable to meet any stated dispatch or delivery dates or times we will inform you as to the progress of your order. You agree and accept that under no circumstances will we accept cancellation of order or refund.

Signature On Delivery

  • Most of our shipments contain valuable items. If you will not be in attendance to accept delivery of your purchase, consider shipping to someone you trust will be able to sign for your package. For your convenience, you may prefer to have your order delivered to your office address. If you choose this option, please include the name of your business in the address. Please note, if you choose this option, goods may be left with reception or the Mail Room.
  • As our carriers require a signature on delivery, the carrier will leave a calling card if you are not at home. Please contact the carrier to reschedule delivery.
  • For postal deliveries, no signature is required and order status tracking is not available.
  • Delivery failure due to no one answering the door upon the arrival of goods at the appointed time, or to circumstantial limitations such as the entrance being too small, will require a rescheduled delivery and therefore incur double delivery charges.
  • We will deliver the merchandise ordered by you to the address you give us for delivery at the time you make your order through our staff or a third party provider. You agree to present your photo identification upon request when you acknowledge receipt of the merchandise. The merchandise shall be, and shall be deemed to be, delivered and accepted by you when the merchandise are delivered to the address you give us for delivery. You agree and accept that we are entitled, at our option, to charge you additional costs or cancel your order in the event of your failure to accept delivery for whatever reasons.

Powerful Compact HEVC Field Unit for On-the-go Live Streaming

The LU300 is a small-sized, cost-effective and reliable HEVC encoder, enabling broadcasters and other content creators to transmit high-quality video on-the-go.

With LiveU's professional-grade hardware HEVC technology as its core, the LU300 combines high-quality video performance with extreme bandwidth efficiency. Content creators can provide the same video quality as H.264 while using about half the bandwidth. In cases where original H.264 bitrate is maintained, the LU300 HEVC offers greatly improved video quality.

Native 5G field unit for extra reliability

With inherent support for 5G, the LU300 delivers the highest bandwidth and ultra-low latency. Two external LiveU 5G cellular modem sticks can be connected for higher bandwidth productions and greater reliabilit. The LU300 offers rock-solid reliability in the most challenging scenarios.

Mission-critical IP bonding in a small form-factor

Weighing just over 900 g (2 lb), the LU300 offers resilient bonding in a compact and lightweight portable unit! Supporting up to 12 Mbps with PRO licenese, the unit combines up to six IP connections: 4 cellular, WiFi and LAN, based on LiveU’s patented HEVC bonding technology.

LRT™ (LiveU Reliable Transport)

LiveU’s unique Reliable Transport protocol (LRT™) is at the heart of LiveU products to deliver optimized video performance. LRT™ enables reliable, low delay live video streaming over non-guaranteed IP networks and ensures reliable transport over the most unreliable of networks, including cellular networks - allowing you to acquire exciting live content in even the most remote locations.


LRT uses numbered packets so that the packets can be re-ordered when they arrive out of order. Packet Ordering is an absolute requirement with connection bonding, where data usually arrives in a different order than intended.


Forward Error Correction (FEC) adds some overhead to the stream to recover lost data faster. LRT automatically varies the FEC parameters based on monitored network conditions.


LRT can acknowledge large groups of packets if they all arrived. If some did not arrive, it can inform the streaming engine to resend needed data. By acknowledging large groups of packets at a time, LRT uses less overhead and latency. Unlike UDP, LRT gives complete feedback loop so the user knows that the data is arriving correctly.


As the bandwidth condition changes, LRT automatically recognizes this and informs the video encoder to allow it to adapt the bit rate of video it is delivering and keep the best possible stream within the available bandwidth at any given moment.
