DATA CHARACTER-A data character is a combination of a byte value with the control variable equal to D.

DWORD-A Dword is thirty-two (32) bits of data. A Dword may be represented as 32 bits, as two adjacent words, or as four adjacent bytes. When shown as bits the least significant bit is bit 0 and most significant bit is bit 31. The most significant bit is shown on the left. When shown as words the least significant word (lower) is word 0 and the most significant (upper) word is word 1. When shown as bytes the least significant byte is byte 0 and the most significant byte is byte 3.

DWORD SYNCHRINIZATION-The state in which a receiver has recognized the comma sequence and is producing an aligned data stream of Dwords (four contiguous bytes) from the zero-reference of the comma character.

ENCODED CHARACTER-An encoded character is the output of the 8b/10b encoder – the result of encoding a character. An encoded character consists of 10 bits, where bit 0 is the most significant bit and bit 9 is the least significant. The bits in an encoded character are symbolically referred to as “abcdeifghj” where “a” corresponds to bit 0 and “j” corresponds to bit 9.

ELASTICITY BUFFER-The elasticity buffer is a portion of the receiver where character slipping and/or character alignment is performed.

FIRST PARTY DMA ACCESS -First-party DMA access is a method by which a device accesses host memory.

FIRST PARTY DMA MODE (FPDMA) - A device which is operating in First-party DMA mode uses First- party DMA as a primary communications method between the host and the device. A software driver uses legacy mode commands to place the device into First-party DMA mode of operation. The legacy-mode command places the device into the First-party DMA mode of operation and the command protocol used between a device and host when in First-party DMA mode are not specified by this specification.

FIRST DATA PHASE- The FPDMA Data Phase is the period from the reception of a DMA Setup FIS until either the exhaustion of the associated data transfer count or the assertion of the ERR bit in the shadow Status register.

FIS-Stands for Frame Information Structure.

FRAME UNFIORMATION STRUCTURE-The user payload of a frame, does not include the SOF, CRC, and EOF delimiters.

Frame-A frame is an indivisible unit of information exchanged between a host and device. A frame consists of a SOF primitive, a Frame Information Structure, a CRC calculated over the contents of the FIS, and an EOF primitive-

LEGACY MODE-Legacy mo d e is the mode of operation which provides software-transparent communication of commands and status between a host and device using the ATA Command Block and Control Block registers.

LEGAL CHARACTER-Legal character is one for which there exists a valid decoding, either into the data character or control character fields. Due to running disparity constraints not all 10-bit combinations result in a legal character. Additional usage restrictions in Serial ATA result in a further reduction in the SATA defined control character space.

OOB SIGNAL DETECTOR-This block decodes Out of Band signal from the high speed input signal path.

This clarity is crucial for identifying details, whether for security purposes or monitoring activities around the clock. It can accommodate multiple camera inputs, allowing users to expand their surveillance network seamlessly.

One of the standout features of the M8-DVR is its remarkable storage capacity. Equipped with advanced hard disk technology, it can store several terabytes of footage, which can be further expanded using additional drives. This means that even with continuous recording, users won’t have to worry about running out of storage quickly. The device also incorporates efficient compression technologies, such as H.265, which allows for reduced file sizes without sacrificing video quality.

In terms of connectivity, the M8-DVR offers various options, including Ethernet ports for network connectivity, USB ports for data transfer, and HDMI output for direct connection to monitors. This versatility allows users to easily stream live footage or review recordings on larger screens. The device supports remote viewing through mobile applications, allowing users to monitor their property from virtually anywhere in real-time.

User experience is further enhanced by an intuitive interface that makes navigation simple and efficient. It includes features like motion detection and alerts, which notify users of any unusual activities. The advanced search function is another highlight, enabling users to quickly locate specific events in their recordings without long hours of scrolling.

The Samsung M8-DVR is also designed with durability in mind. It comes with robust security features to protect against unauthorized access and offers backup options to prevent data loss. With its blend of technology, storage capabilities, and user-friendly design, the Samsung M8-DVR stands out as a comprehensive solution for modern video surveillance needs, making it an essential tool for enhancing security and peace of mind in any environment.
