Performance characterization of a low-cost video codec on portable devices

Bandwidth and processing requirements of conventional multimedia applications typically exceed capabilities of current technology portable terminals. Applications should hence be able to accommodate their requirements to run on these devices. In this paper we provide a complete performance characterization of a prototypal video codec based on techniques which trade-off complexity with reproduction quality. Comparison with standard codecs like H263 and MPEG-4 demonstrates a remarkable reduction of coding times, potentially enabling real-time processing of multimedia data on low-power devices. However, these performance gains are achieved at expenses of PNSR, making the approach suited to applications like videoconferencing only if a limited quality is acceptable. Our analysis also points out and quantifies some limitations of current technology lowpower devices.
