“…c) An example of a high-performance HEVC system uses an all-intra FPGA-accelerated encoder by Sjövall et al [129] and a GPU-accelerated decoder by Wang et al [145]. Since [129] does not specify encoded bitstream size, it is extracted form a follow-up demonstrator by Viitamäki et al [140] where the encoded bitstream was 21 Mb/s for a 4K@30FPS video. Both the encoder and the decoder require high-performance servers which limits their usability in consumer applications.…”

The next generation of wireless networks fosters the adoption of latency-critical applications such as XR, connected industry, or autonomous driving. This survey gathers implementation aspects of different image and video coding schemes and discusses their tradeoffs. Standardized video coding technologies such as HEVC or VVC provide a high compression ratio, but their enormous complexity sets the scene for alternative approaches like still image, mezzanine, or texture compression in scenarios with tight resource or latency constraints. Regardless of the coding scheme, we found inter-device memory transfers and the lack of sub-frame coding as limitations of current full-system and software-programmable implementations.
