Ameerika firmas 8×8 toodetud videotelefoni kaamerat saab juhtida kaugjuhtimise teel, sest kaamerasilma võib zoom’ida, pöörata, kallutada, pilti fokuseerida ja teha stoppkaadreid.
Videotelefoni tegelikku kasutuselevõttu on takistanud asjaolu, et see vajab palju suuremat ribalaiust kui tavaline telefon, olenemata sellest, kas on tegu analoog- või digitaaltelefoniga. Videotelefoni ribalaiust saab vähendada, kui kasutada minimaalset rahuldavat kujutise lahutusvõimet ja kasutades mitte värvilist, vaid mustvalget pilti, samuti edastades iga mõne sekundi järel liikumatuid pilte, mitte pidevalt liikuvat videopilti.
A still image video camera which can record, play back and erase a series of still images without sound. The images are stored on a floppy disk and can be played back through a television screen.
Video compression is measured by four basic criteria: compression ratio, picture quality, compression and decompression speeds, and the hardware and software resources required to achieve it. Use of compression with motion video is mandatory, but it also benefits still images, particularly in multimedia applications where the end-user should not be left waiting for things to happen on the screen. Processing of a single image in one second or less is generally acceptable for a still picture, but motion video requires at least 15 fps to produce the effect of smooth movement.
