A video clip level content management and control method and system

ActiveCN121792808BReduce CPU usageEliminate microstuttering
This invention relates to the field of multimedia video processing and playback control technology, specifically a video segment-level content management and control method and system, comprising: a time-series discrete mapping step: obtaining a server-side rule set and mapping it to a time-series state index structure with video durations divided into discrete-time graticles; an asynchronous look-ahead detection step: calculating the look-ahead time based on the current playback time using an independent asynchronous thread and reading the corresponding graticle data from the bitmap; an instruction generation and caching step: generating instruction objects based on graticle control identifiers using preprocessing logic and pushing them sequentially into an instruction circular queue; and a frame-level synchronous application step: checking the queue during main playback thread rendering, and applying the instruction if the current time matches the instruction trigger time. This invention reduces playback CPU usage, eliminates micro-stuttering caused by main thread blocking, and ensures accurate triggering of control logic at the frame level.

Address conversion-based capacity expansion method, system, device, storage medium and program product for fixed-length counting array counting overflow

PendingCN122507656Asave memory spaceInterest rates are highData classAlgorithm
This invention discloses a method, system, device, storage medium, and program product for expanding the capacity of a fixed-length counting array based on address translation to prevent overflow. The method includes the following steps: Step 1: Determine the data type and length of the array counting, and allocate contiguous memory; Step 2: Check if the highest column of the array counting has overflowed. If not, increment the count; if overflowed, jump to Step 3; Step 3: Check the non-highest bit. If the lower 15 bits of the address are not all zeros, jump to Step 4; if they are all zeros, jump to Step 5; Step 4: Calculate the new address position based on the offset of the lower 15 bits, and jump to Step 6; Step 5: Allocate a new memory block, record the offset between the new and old addresses in the lower 15 bits of the original address, and jump to Step 6; Step 6: Increment the uint32 type count of the new address by 1, check if the highest bit is 1. If the highest bit is 1, overflow occurs again, and steps 5 to 6 are repeated. This invention provides an address translation-based scheme that can continue to collect counts and avoid copying existing memory, thus avoiding memory waste, and providing efficient statistical and query performance.
