  • Multi-channel electronic programming guide and soft picture-in-picture acquisition for use with digital television
    Patent number: 6212680
    Abstract: Multi-channel Electronic Program Guide acquisition and soft picture-in-picture system for use with digital television receiver. The digital television receiver uses its central processing unit (CPU) to perform a software decode of packets received from a main tuner and/or a picture-in-picture. This allows the CPU to display video from pictures within the same RF channel or within another channel simultaneously with video information decoded in real-time by a hardware decoder. Also, in the case of a digital television with two tuners, the CPU can acquire and accumulate EPG data from multiple channels.
