First Claim
1. A method, comprising:
- receiving by a video stream receive-and-process (VSRP) device in a first interval a first video stream, the first video stream corresponding to a first picture resolution format (PRF), the first video stream comprising a first video service in the first PRF, the first video service having an intended picture output as a sequence of pictures in the first PRF;
processing by the VSRP device the first video stream by allocating resources required to process the sequence of pictures of the first video service according to the first PRF of the intended picture output;
receiving by the VSRP device in a second interval a second video stream, the second video stream corresponding to a second PRF, the second video stream comprising a second video service in the second PRF, the second video service having an intended output as a sequence of pictures in the second PRF;
processing by the VSRP device the second video stream by allocating resources required to process the sequence of pictures of the second video service according to the second PRF of the intended picture output;
receiving by the VSRP device in a third interval a third video stream and auxiliary information, the third video stream comprising a third video service in the first PRF in a first portion of the third interval and in the second PRF in a second portion of the third interval, the first and second portions having a different intended picture output; and
processing by the VSRP device the third video stream by allocating a fixed number of resources based on the auxiliary information to process the first portion and the second portion.
