Systems and methods for clock synchronization are disclosed in which a primary node generates special physical laver clock sync symbols from the output of a reference clock and inserts the clock sync symbols within a symbol stream to one or more secondary nodes. Upon receiving a symbol stream, a secondary node can extract the clock sync symbols from the stream to synchronize its local clock with the reference clock of the primary node. In particular, the clock sync symbols can be inserted into the symbol stream at any arbitrary symbol location, e.g., even between consecutive symbols of a symbol encoded data frame. The clock sync symbols can also replace some control symbols in the symbol stream, such as idle or comma symbols. Accordingly, the clock sync symbols can be inserted into a symbol stream at fixed intervals, irregular intervals, or at any arbitrary time for high resolution clock synchronization.

The present invention provides a method for acquiring and allocating logical timestamps in a distributed database. The method comprises a timestamp proxy module on each server node that sends timestamp request requests to a global timestamp manager at fixed intervals and receives timestamps allocated by the global timestamp manager. The timestamp proxy module caches the requested timestamp time (Treq) and the allocated timestamp in a timestamp cache module. When processing a transaction, the transaction's requested timestamp time (Tstart) is compared with the timestamp cached by the timestamp cache module. If Treq ≥ Tstart, the currently cached timestamp is used as the transaction's timestamp. Otherwise, the transaction module is put into sleep mode for a set period of time, ensuring that the updated timestamp is ≥ Tstart, and the updated timestamp is used as the transaction's timestamp.

Chunk based video encoding involves dividing a video into chunks with varying lengths based on the content within those frames. In contrast, dividing the video at a fix interval is prone to generating chunks starting at the middle of hard to encode areas, which can lead to a loss of encoder rate-control efficiency and produce visual quality gaps at the beginning of such chunks. The system can identify a set of boundaries for dividing the video into chunks having similar lengths and with little to no impact on visual quality. The boundaries of the chunks are placed at locations (or frames) that are far from the complex (or hard to encode) areas of the video. To do so, the system evaluates the video using various complexity metrics to identify the complex areas that require more bits to encode relative to less complex areas.

The present invention facilitates the reduction of power consumption in a CPU when media data, which is repeatedly inputted by each user at fixed intervals, is inputted into a general-purpose server or the like and processed. In this invention, a type of processing to be performed on data of each user is specified such that each processing is subjected to classification by the processing type, and preferentially allocated to a different logical core or the like. Power saving control of each logical core is performed by reflecting processing characteristics for each processing type. In the case of transcoding, the classification of decoding, data conversion, and encoding, and differences in codecs is reflected in the allocation of logical cores or the like. The allocation of logical cores or the like is determined by reflecting a difference in distance corresponding to a hierarchical structure of a cache memory so as to improve a cache hit rate at a time when each logical core accesses the data. Data processing of the processing type having a large processing load is divided into a plurality of parts and allocated to the plurality of logical cores in a distributed manner. Data processing of the processing type that has a large processing load and cannot be performed only by a single logical core is allocated first.
